b46d393061 Switch the Cascadia projects to til::color where it's easily possible to do so (#5847)
This pull request moves swaths of Cascadia to use `til::color` for color
interop. There are still some places where we use `COLORREF`, such as in
the ABI boundaries between WinRT components.

I've also added two more til::color helpers - `with_alpha`, which takes
an existing color and sets its alpha component, and a
`Windows::UI::Color` convertor pair.

Future direction might include a `TerminalSettings::Color` type at the
idl boundary so we can finally stop using UInt32s (!) for color.

## Validation Steps Performed
Tested certain fragile areas:
* [x] setting the background with OSC 11
* [x] setting the background when acrylic is in use (which requires
  low-alpha)

6394e5d70b Remove the JSON reserializers (except for AKB) (#5918)
The AKB serializer is used in the tracelogging pipeline.

Chatted with @zadjii-msft about ganking the deserializers. The form
they'll take in the future is probably very different from this.

We'll need to have some better tracking of the _source_ or _pass_ a
setting was read during so that we can accurately construct an internal
settings attribution model. Diffing was very extremely cool, but we
didn't end up needing it.

This apparently drops our binary size by a whopping _zero bytes_ because
the optimizer was smarter than us and actually totally deleted it.

c39f9c6626 CodepointWidthDetector: reclassify U+25FB, U+25FC as Narrow (#5914)
This seems to be in line with the emoji-sequences table in the latest
version of the Unicode standard: those glyphs require U+FE0F to activate
their emoji presentation. Since we don't support composing U+FE0F, we
should not present them as emoji by default.

Fixes #5910.

Yes, I hate this.

2453e8e1ed Rename propsheet/TerminalPage to propsheet/TerminalPropsheetPage (#5882)
My workflow is to use Sublime's <kbd>Ctrl+P</kbd> shortcut to navigate to files by name. However, the propsheet version of the files _always_ comes up before the `TerminalApp` one does. This results in me having to close the file and re-open the right one.

This PR renames the propsheet one, so it's unambiguous which one I'm opening.

It's really the most trivial nit.

1422714af6 Manually close tabs when they're closed while dragging them (#5883)
## Summary of the Pull Request

When we're dragging the tab around, if you execute a `ClosePane`/`CloseTab`, then we should make sure to actually activate a new tab, so that focus doesn't just fall into the void.

## References

* This is almost exactly #5799, but with rearranging tabs

## PR Checklist
* [x] Closes #5559
* [x] I work here
* [ ] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments
We suppress `_OnTabItemsChanged` events during a rearrange, so if a tab is closed while we're rearranging tabs, the we don't fire the `SelectionChanged` event that we usually do during a close that would select the new tab.

## Validation Steps Performed
* Tested manually
  - Confirmed that tragging a tab out, closing it, then dragging it back in does nothing.

b4c33dd842 Fix an accidental regression from #5771 (#5870)
This PR reverts a relatively minor change that was made incorrectly to
ConPTY in #5771.

In that PR, I authored two tests. One of them actually caught the bug
that was supposed to be fixed by #5771. The other test was simply
authored during the investigation. I believed at the time that the test
revealed a bug in conpty that was fixed by _removing_ this block of
code. However, an investigation itno #5839 revealed that this code was
actually fairly critical. 

So, I'm also _skipping_ this buggy test for now. I'm also adding a
specific test case to this bug.

The problem in the bugged case of `WrapNewLineAtBottom` is that
`WriteCharsLegacy` is wrapping the bottom row of the ConPTY buffer,
which is causing the cursor to automatically move to the next line in
the buffer. This is because `WriteCharsLegacy` isn't being called with
the `WC_DELAY_EOL_WRAP` flag. So, in that test case, 
* The client emits a wrapped line to conpty
* conpty fills the bottom line with that text, then dutifully increments
  the buffer to make space for the cursor on a _new_ bottom line.
* Conpty reprints the last `~` of the wrapped line
* Then it gets to the next line, which is being painted _before_ the
  client emits the rest of the line of text to fill that row.
* Conpty thinks this row is empty, (it is) and manually breaks the row. 

However, the test expects this row to be emitted as wrapped. The problem
comes from the torn state in the middle of these frames - the original
line probably _should_ remain wrapped, but this is a sufficiently rare
case that the fix is being punted into the next release. 

It's possible that improving how we handle line wrapping might also fix
this case - currently we're only marking a row as wrapped when we print
the last cell of a row, but we should probably mark it as wrapped
instead when we print the first char of the _following_ row. That work
is being tracked in #5800

### The real bug in this PR

The problem in the `DeleteWrappedWord` test is that the first line is
still being marked as wrapped. So when we get to painting the line below
it, we'll see that there are no characters to be printed (only spaces),
we emit a `^[20X^[20C`, but the cursor is still at the end of the first
line. Because it's there, we don't actually clear the text we want to
clear.

So DeleteWrappedWord, #5839 needs the `_wrappedRow = std::nullopt;`
statement here.

cf62922ad8 Revert some emoji back to narrow width
A couple of codepoints, namely the card suites, male and female signs,
and white and black smiling faces were changed to have a two-column
width as part of #5795 since they were specified as emoji in Unicode's
emoji list v13.0[1]. 

These particular glyphs also show up in some of the most fundamental
code pages, such as CP437[2] and WGL4[3]. We should
not be touching the width of the glyphs in these codepages, as suddenly
changing a long-time-running narrow glyph to use two-columns all of a
sudden will surely break (and has already broken) things.

fcd5bb39f0 Stop trying to set selection endpoints when there's no selection (#5855)
It turns out that we weren't really adequately guarding calls to
SetSelectionEnd and friends.

We're clearing the active selection when the window resizes, but we're
doing so by nulling out the std::optional<Selection> it lives in. Later,
though, when we set the selection endpoint we're using "_selection->".

Optional's operator-> has undefined behavior when the optional doesn't
have a value in it.

In our case, it looks like it was returning whatever the value was prior
to it being emptied out. PivotSelection would attempt to access an
out-of-bounds coordinate when the buffer got smaller during a resize.

The solution is to guard both levels of selection endpoint manipulation
in a check for an active selection.

Apparently, this accounts for somewhere between 7% and 14% of our
crashes on 1.0RC1.

Repro was:
Use Win+Arrow to snap the window while in the middle of a selection.

d01317c9db Add renderer settings to mitigate blurry text for some graphics devices
## Summary of the Pull Request
Adds user settings to adjust rendering behavior to mitigate blurry text on some devices.

## References
- #778 introduced this, almost certainly.

## PR Checklist
* [x] Closes #5759, mostly
* [x] I work here.
* [ ] We need community verification that this will help.
* [x] Updated schema and schema doc.
* [x] Am core contributor. Discussed in Monday sync meeting and w/ @DHowett-MSFT. 

## Detailed Description of the Pull Request / Additional comments
When we switched from full-screen repaints to incremental rendering, it seems like we exposed a situation where some display drivers and hardware combinations do not handle scroll and/or dirty regions (from `IDXGISwapChain::Present1`) without blurring the data from the previous frame. As we're really close to ship, I'm offering two options to let people in this situation escape it on their own. We hope in the future to figure out what's actually going on here and mitigate it further in software, but until then, these escape hatches are available.

1. `experimental.rendering.forceFullRepaint` - This one restores the pre-778 behavior to the Terminal. On every single frame paint, we'll invalidate the entire screen and repaint it.
2. `experimental.rendering.software` - This one uses the software WARP renderer instead of using the hardware and display driver directly. The theory is that this will sidestep any driver bugs or hardware variations.

One, the other, or both of these may be field-applied by users who are experiencing this behavior. 

Reverting #778 completely would also resolve this, but it would give back our largest performance win in the whole Terminal project. We don't believe that's acceptable when seemingly a majority of the users are experiencing the performance benefit with no detriment to graphical display.

## Validation Steps Performed
- [x] Flipped them on and verified with the debugger that they are being applied to the rendering pipeline
- [ ] Gave a private copy to community members in #5759 and had them try whether one, the other, or both resolved their issue.

e7a2732ffb Refactor the SGR implementation in AdaptDispatch (#5758)
This is an attempt to simplify the SGR (Select Graphic Rendition)
implementation in conhost, to cut down on the number of methods required
in the `ConGetSet` interface, and pave the way for future improvements
and bug fixes. It already fixes one bug that prevented SGR 0 from being
correctly applied when combined with meta attributes.

* This a first step towards fixing the conpty narrowing bugs in issue
  #2661
* I'm hoping the simplification of `ConGetSet` will also help with
  #3849.
* Some of the `TextAttribute` refactoring in this PR overlaps with
  similar work in PR #1978. 

## Detailed Description of the Pull Request / Additional comments

The main point of this PR was to simplify the
`AdaptDispatch::SetGraphicsRendition` implementation. So instead of
having it call a half a dozen methods in the `ConGetSet` API, depending
on what kinds of attributes needed to be set, there is now just one call
to get current attributes, and another call to set the new value. All
adjustments to the attributes are made in the `AdaptDispatch` class, in
a simple switch statement.

To help with this refactoring, I also made some change to the
`TextAttribute` class to make it easier to work with. This included
adding a set of methods for setting (and getting) the individual
attribute flags, instead of having the calling code being exposed to the
internal attribute structures and messing with bit manipulation. I've
tried to get rid of any methods that were directly setting legacy, meta,
and extended attributes.

Other than the fix to the `SGR 0` bug, the `AdaptDispatch` refactoring
mostly follows the behaviour of the original code. In particular, it
still maps the `SGR 38/48` indexed colors to RGB instead of retaining
the index, which is what we ultimately need it to do. Fixing that will
first require the color tables to be unified (issue #1223), which I'm
hoping to address in a followup PR.

But for now, mapping the indexed colors to RGB values required adding an
an additional `ConGetSet` API to lookup the color table entries. In the
future that won't be necessary, but the API will still be useful for
other color reporting operations that we may want to support. I've made
this API, and the existing setter, standardise on index values being in
the "Xterm" order, since that'll be essential for unifying the code with
the terminal adapter one day.

I should also point out one minor change to the `SGR 38/48` behavior,
which is that out-of-range RGB colors are now ignored rather than being
clamped, since that matches the way Xterm works.

## Validation Steps Performed

This refactoring has obviously required corresponding changes to the
unit tests, but most were just minor updates to use the new
`TextAttribute` methods without any real change in behavior. However,
the adapter tests did require significant changes to accommodate the new
`ConGetSet` API. The basic structure of the tests remain the same, but
the simpler API has meant fewer values needed to be checked in each test
case. I think they are all still covering the areas there were intended
to, though, and they are all still passing.

Other than getting the unit tests to work, I've also done a bunch of
manual testing of my own. I've made sure the color tests in Vttest all
still work as well as they used to. And I've confirmed that the test
case from issue #5341 is now working correctly.

7ae34336da Make most emojis full-width (#5795)
The table that we refer to in `CodepointWidthDetector.cpp` to determine
whether or not a codepoint should be rendered as Wide vs Narrow was
based off EastAsianWidth[1].  If a codepoint wasn't included in this
table, they're considered Narrow. Many emojis aren't specified in the
EAW list, so this PR supplements our table with emoji codepoints from
emoji-data[2] in order to render most, if not all, emojis as full-width. 

There are certain codepoints I've added to the comments (in case we want
to add them officially to the table in the future) that Microsoft
decided to give an emoji presentation even if it's specified as
Narrow/Ambiguous in the EAW list and are _not_ specified in the Unicode
emoji list. These include all of the Mahjong Tiles block, different
direction pencils (✎✐), different pointing index fingers (☜, ☞) among
others. I have no idea if I've captured all of them, as I don't know of
an easy way to detect which are Microsoft specific emojis.

## Validation Steps Performed
I have looked at so many emojis that I dream emoji.

These screenshots aren't encompassing _all_ emoji but I've tried to grab
a couple from all across the codepoint ranges:

38472719d5 Fix wrapped lines in less in Git for Windows (#5771)
## Summary of the Pull Request

This PR resolves an issue with the Git for Windows (MSYS) version of `less`. It _doesn't_ use VT processing for emitting text tothe buffer, so when it hits `WriteCharsLegacy`, `WC_DELAY_EOL_WRAP` is NOT set.

When this happens, `less` is writing some text that's longer than the width of the buffer to the last line of the buffer. We're hitting the 
```c++
    Status = AdjustCursorPosition(screenInfo, CursorPosition, WI_IsFlagSet(dwFlags, WC_KEEP_CURSOR_VISIBLE), psScrollY);
```
call in `_stream.cpp:560`.

The cursor is _currently_ at `{40, 29}`, the _start_ of the run of text that wrapped. We're trying to adjust it to `{0, 30}`, which would be the start of the next line of the buffer. However, the buffer is only 30 lines tall, so we've got to `IncrementCircularBuffer` first, so we can move the cursor there.

When that happens, we're going to paint frame. At the end of that frame, we're going to try and paint the cursor position. The cursor is still at `{40, 29}` here, so unfortunately, the `cursorIsInDeferredWrap` check in `XtermEngine::PaintCursor` is `false`. That means, conpty is going to try to move the cursor to where the console thinks the cursor actually is at the end of this frame, which is `{40, 29}`.

If we're painting the frame because we circled the buffer, then the cursor might still be in the position it was before the text was written to the buffer to cause the buffer to circle. In that case, then we DON'T want to paint the cursor here either, because it'll cause us to manually break this line. That's okay though, the frame will be painted again, after the circling is complete.

## Detailed Description of the Pull Request / Additional comments

### Background
- We want the Terminal to be fast at drawing. To be fast at drawing, we perform differential drawing, or only drawing what is different from the previous frame. We use DXGI's `Present1` method to help us with this as it helps us compose only the deltas onto the previous frame at drawing time and assists us in scrolling regions from the previous frame without intervention. However, it only works on strictly integer pixel row heights.
- Most of the hit testing and size-calculation logic in both the `conhost` and the Terminal products are based on the size of an individual cell. Historically, a cell was always dictated in a `COORD` structure, or two `SHORT` values... which are integers. As such, when we specify the space for any individual glyph to be displayed inside our terminal drawing region, we want it to fall perfectly inside of an integer box to ensure all these other algorithms work correctly and continue to do so.
- Finally, we want the Terminal to have font fallback and locate glyphs that aren't in the primary selected font from any other font it can find on the system that contains the glyph, per DirectWrite's font fallback mechanisms. These glyphs won't necessarily have the same font or glyph metrics as the base font, but we need them to fit inside the same cell dimensions as if they did because the hit testing and other algorithms aren't aware of which particular font is sourcing each glyph, just the dimensions of the bounding box per cell.

### How does Terminal deal with this?
- When we select a font, we perform some calculations using the design metrics of the font and glyphs to determine how we could fit them inside a cell with integer dimensions. Our process here is that we take the requested font size (which is generally a proxy for height), find the matching glyph width for that height then round it to an integer. We back convert from that now integer width to a height value which is almost certainly now a floating point number. But because we need an integer box value, we add line padding above and below the glyphs to ensure that the height is an integer as well as the width. Finally, we don't add the padding strictly equally. We attempt to align the English baseline of the glyph box directly onto an integer pixel multiple so most characters sit crisply on a line when displayed. 
- Note that fonts and their glyphs have a prescribed baseline, line gap, and advance values. We use those as guidelines to get us started, but then to meet our requirements, we pad out from those. This results in fonts that should be properly authored showing gaps. It also results in fonts that are improperly authored looking even worse than they normally would.

### Now how does block and line drawing come in?
- Block and Line drawing glyphs are generally authored so they will look fine when the font and glyph metrics are followed exactly as prescribed by the font. (For some fonts, this still isn't true and we want them to look fine anyway.)
- When we add additional padding or rounding to make glyphs fit inside of a cell, we can be adding more space than was prescribed around these glyphs. This can cause a gap to be visible.
- Additionally, when we move things like baselines to land on a perfect integer pixel, we may be drawing a glyph lower in the bounding box than was prescribed originally.

### And how do we solve it?
- We identify all glyphs in the line and block drawing ranges.
- We find the bounding boxes of both the cell and the glyph.
- We compare the height of the glyph to the height of the cell to see if we need to scale. We prescribe a scale transform if the glyph wouldn't be tall enough to fit the box. (We leave it alone otherwise as some glyphs intentionally overscan the box and scaling them can cause banding effects.)
- We inspect the overhang/underhang above and below the boxes and translate transform them (slide them) so they cover the entire cell area.
- We repeat the previous two steps but in the horizontal direction.

d77745d035 Manually select a new tab when we're in fullscreen mode (#5809)
If we're fullscreen, the TabView isn't `Visible`. If it's not `Visible`,
it's _not_ going to raise a `SelectionChanged` event, which is what we
usually use to focus another tab. Instead, we'll have to do it manually
here.

So, what we're going to try to do is move the focus to the tab to the
left, within the bounds of how many tabs we have.

EX: we have 4 tabs: [A, B, C, D]. If we close:
* A (`tabIndex=0`): We'll want to focus tab B (now in index 0)
* B (`tabIndex=1`): We'll want to focus tab A (now in index 0)
* C (`tabIndex=2`): We'll want to focus tab B (now in index 1)
* D (`tabIndex=3`): We'll want to focus tab C (now in index 2)

`_UpdatedSelectedTab` will do the work of setting up the new tab as the
focused one, and unfocusing all the others.

Also, we need to _manually_ set the SelectedItem of the tabView here. If
we don't, then the TabView will technically not have a selected item at
all, which can make things like ClosePane not work correctly.

[Git2Git] Merged PR 4644345: conhost: disable the DX renderer in inbox builds

We're going to be taking on some changes to the Dx renderer that are at
the very least annoying and at the very most inconsequential to the
inbox console. This commit removes support for the DX renderer from the
inbox console.

SizeBench reports that ConRenderDx contributes 55.1kb to the conhost
image (as its third largest constituent library), so this should net us
a couple pleasant WPG improvements down the line.

7a251d85f7 Don't set the new tab button colors for now (#5749)
This is actually related to another issue we have, #3917. I think if the system is set to "Dark" theme, but the app is set to light theme, then the brush lookup in `_ClearNewTabButtonColor` still returns to us the dark theme brushes.

Fortunately, since we're not actually setting the color of the new tab button anymore, we can just remove the call to that method now, and loop back on it later.

9fe624ffbc Make sure that EraseAll moves the Terminal viewport (#5683)
The Erase All VT sequence (`^[[2J`) is supposed to erase the entire
contents of the viewport. The way it usually does this is by shifting
the entirety of the viewport contents into scrollback, and starting the
new viewport below it. 

Currently, conpty doesn't propagate that state change correctly. When
conpty gets a 2J, it simply erases the content of the connected
terminal's viewport, by writing over it with spaces. Conpty didn't
really have a good way of communicating "your viewport should move", it
only knew "the buffer is now full of spaces".

This would lead to bugs like #2832, where pressing <kbd>ctrl+L</kbd> in
`bash` would delete the current contents of the viewport, instead of
moving the viewport down.

This PR makes sure that when conpty sees a 2J, it passes that through
directly to the connected terminal application as well. Fortunately, 2J
was already implemented in the Windows Terminal, so this actually fixes
the behavior of <kbd>ctrl+L</kbd>/`clear` in WSL in the Terminal.

## References

* #4252 - right now this isn't the _most_ optimal scenario, we're
  literally just printing a 2J, then we'll perform "erase line" `height`
  times. The erase line operations are all redundant at this point - the
  entire viewport is blank, but conpty doesn't really know that.
  Fortunately, #4252 was already filed for me to come through and
  optimize this path.

624a553d23 Add support for setting a tab's color at runtime w/ context menu (#3789)
This commit introduces a context menu for Tab and a new item,
"Color...", which will display a color picker.

A flyout menu, containing a custom flyout, is attached to each tab. The
flyout displays a palette of 16 preset colors and includes a color
picker. When the user selects or clears color, an event is fired, which
is intercepted by the tab to which the flyout belongs.

The changing of the color is achieved by putting the selected color in
the resource dictionary of the tab, using well-defined dictionary keys
(e.g. TabViewItemHeaderBackground). Afterwards the visual state of the
tab is toggled, so that the color change is visible immediately.

Custom-colored tabs will be desaturated (somewhat) by alpha blending
them with the tab bar background.

The flyout menu also contains a 'Close' flyout item.

## Validation Steps Performed
I've validated the behavior manually: start the program via the start
menu. Right click on the tab -> Choose a tab color.

The color flyout is going to be shown. Click a color swatch or click
'Select a custom color' to use the color picker. Use the 'Clear the
current color' to remove the custom color.

Closes #2994. References #3327.

<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
This fixes the RTL regression caused in #4747. We create the rectangle taking the direction (through the BiDi Level) into account, and then the rendering works again. The GlyphRun shaping could still probably use some work to be a polished thingy, and there are still issues with RTL getting chopped up a lot when there's font fallback going on, but this fixes the regression, and it's now functional again.

## Detailed Description of the Pull Request / Additional comments
The baseline is actually direction dependent. So when it was being initialized, the unconditional baseline as left broke it, setting the box off to right of the text. We just check if the `GlyphRun->bidiLevel` is set, and if so, we adjust it so that the baseline lines up with the right, not with the left.

7612044363 Implement a pair of shims for cls, Clear-Host in conpty mode (#5627)
## Summary of the Pull Request

This PR implements a pair of shims for `cmd` and `powershell`, so that their `cls` and `Clear-Host` functions will clear the entire terminal buffer (like they do in conhost), instead of just the viewport. With the conpty viewport and buffer being the same size, there's effectively no way to know if an application is calling these API's in this way with the intention of clearing the buffer or the viewport. We absolutely have to guess. 

Each of these shims checks to see if the way that the API is being called exactly matches the way `cmd` or `powershell` would call these APIs. If it does, we manually write a `^[[3J` to the connected terminal, to get he Terminal to clear it's own scrollback.

~~_⚠️ If another application were trying to clear the **viewport** with an exactly similar API call, this would also cause the terminal scrollback to get cleared ⚠️_~~

* [x] Should these shims be restricted to when the process that's calling them is actually `cmd.exe` or `powershell.exe`? Can I even do this? I think we've done such a good job of isolating the client process information from the rest of the host code that I can't figure out how to do this.
  - YES, this can be done, and I did it.
* [ ] **TODO**: _While I'm here_, should I have `DoSrvPrivateEraseAll` (the implementation for `^[[2J`, in `getset.cpp`) also manually trigger a EraseAll in the terminal in conpty mode?

b6a21de802 Intentionally leak our Application, so that we DON'T crash on exit (#5629)
We've got a weird crash that happens terribly inconsistently, but pretty
readily on migrie's laptop, only in Debug mode. Apparently, there's some
weird ref-counting magic that goes on during teardown, and our
Application doesn't get closed quite right, which can cause us to crash
into the debugger. This of course, only happens on exit, and happens
somewhere in the `...XamlHost.dll` code.

Crazily, if we _manually leak the `Application`_ here, then the crash
doesn't happen. This doesn't matter, because we really want the
Application to live for _the entire lifetime of the process_, so the only
time when this object would actually need to get cleaned up is _during
exit_. So we can safely leak this `Application` object, and have it just
get cleaned up normally when our process exits.

* [x] I'm pretty sure there's not an actual bug on our repo for this

3246c4250a Bundle the entire CRT with our branded Release packages (#5661)
For our release builds, we're just going to integrate the UWPDesktop CRT
into our package and delete the package dependencies.  It's very
difficult for users who do not have access to the store to get our
dependency packages, and we want to be robust and deployable everywhere.
Since these libraries can be redistributed, it's easiest if we simply
redistribute them.

Our package grows by ~550kb per architecture (compressed) because of
this. I've added validation that we don't have both the libs _and_ the
dependencies in the same package.

Fixes #3097.

17bd8b5750 Grab the write lock before updating the font (#5654)
## Summary of the Pull Request
Based on the discussion in #5479, it seems that the crash is caused by a race condition due to not obtaining the write lock before calling `TriggerFontChange`.

I'm not totally sure if my approach is the right one, but I've taken the lock out of `_RefreshSize` since it seems like all calls of `_RefreshSize` come after a `TriggerFontChange`/`UpdateFont`. Then I just 
made sure all calls of `TriggerFontChange`/`UpdateFont` are preceded with a `LockForWriting`.

If a class has a constructor which can be called with a single argument,
then this constructor becomes conversion constructor because such a
constructor allows conversion of the single argument to the class being

In some header files, there were constructors that took a value that
could involve implicit conversions, so I added explicit to ensure that
does not happen.

## Detailed Description of the Pull Request / Additional comments

Basically, during a resize, we try to restore the viewport position
correctly, and part of that checks where the current commandline ends.
However, when we do that, the commandline's _current_ state still
reflects the _old_ buffer size, so resizing to be smaller can cause us
to throw an exception, when we find that the commandline doesn't fit in
the new viewport cleanly.

By hiding it, then redrawing it, we avoid this problem entirely. We
don't need to perform the check on the old commandline contents (since
they'll be empty), and we'll redraw it just fine for the new buffer size

## Validation Steps Performed

1ce86f8f1a Clamp the new rows scrolling value to a positive number (#5630)
## Summary of the Pull Request

This PR clamp the "new rows" scrolling value to a positive number. We can't create a negative number of new rows. It also adds a test.

## Detailed Description of the Pull Request / Additional comments

The origin of this bug is that as newlines are emitted, we'll accumulate an enormous scroll delta into a selection region, to the point of overflowing a `SHORT`. When the overflow occurs, the `Terminal` would fail to send a `NotifyScroll()` to the `TermControl` hosting it.

For this bug to repro, we need to:
- Have a sufficiently large buffer, because each newline we'll accumulate a delta of (0, ~bufferHeight), so (bufferHeight^2 + bufferHeight) > SHRT_MAX
- Have a selection

db5d2fe0a5 Add and enforce minimum width (#5599)
## Summary of the Pull Request
Enforces a minimum width of 460 wide. This allows tabs to always be seen (albeit partially).

NOTE: A minimum height was originally added to allow the About menu to be seen. This minimum height was removed from this PR because we don't foresee a circumstance where your Terminal is in that state, and you can't just resize it to make the content fit properly.

64f8bbf5ff Adjust TSFInputControl alignment (#5609)
This PR fixes a couple of issues with TSFInputControl alignment:

1. The emoji picker IME in particular would show up overlapping the
   current buffer row because I stupidly didn't realize that
   `TextBlock.ActualHeight` is 0 right after initialization and before
   it has any text. So, the emoji picker will show up on the bottom of
   the 0 height TextBlock, which overlaps the current buffer row. This
   isn't a problem with CJK because inputting text _causes_ the IME to
   show up, so by the time the IME shows up, the TextBlock has text and
   accordingly has a height.
2. It turns out the emoji picker IME doesn't follow the `TextBlock`
   bottom, unlike Chinese and Japanese IME, so if a user were to compose
   near the edge of the screen and let the `TextBlock` start line
   wrapping, the emoji IME doesn't follow the bottom of the `TextBlock`
   as it grows. This means that the `TextBlock` position doesn't update
   in the middle of composition, and the `LayoutRequested` event that it
   fires at the beginning of composition is the only chance we get to
   tell the emoji IME where to place itself. It turns out when we reset
   `TextBlock.Text`, the ActualHeight doesn't get immediately reset back
   to the min size. So if a user were to bring up the emoji IME before
   `ActualHeight` is reset, the IME will show up way below the current
   buffer row.
3. We don't currently `TryRedrawCanvas` when the window position changes
   (resizing, dragging the window around), so sometimes dragging or
   resizing the Terminal doesn't update the position of the IME. Ideally
   it should be listening to some "window position changed" event, but
   alas we don't have that and it would be much harder than this
   incoming fix. We'll just track the window bounds as part of
   `TryRedrawCanvas` and redraw if it changes. For the most part, this
   will allow the IME to update to where the new window position is, but
   it'll only be called if we receive a `LayoutRequested` event.

214163ebb7 Replace the HRGN-based titlebar cutout with an overlay window (#5485)
Also known as "Kill HRGN II: Kills Regions Dead (#5485)"

Copying the description from @greg904 in #4778.

--- 8< ---
My understanding is that the XAML framework uses another way of getting
mouse input that doesn't work with `WM_SYSCOMMAND` with `SC_MOVE`. It
looks like it "steals" our mouse messages like `WM_LBUTTONDOWN`.

Before, we were cutting (with `HRGN`s) the drag bar part of the XAML
islands window in order to catch mouse messages and be able to implement
the drag bar that can move the window. However this "cut" doesn't only
apply to input (mouse messages) but also to the graphics so we had to
paint behind with the same color as the drag bar using GDI to hide the
fact that we were cutting the window.

The main issue with this is that we have to replicate exactly the
rendering on the XAML drag bar using GDI and this is bad because:
1. it's hard to keep track of the right color: if a dialog is open, it
   will cover the whole window including the drag bar with a transparent
   white layer and it's hard to keep track of those things.
2. we can't do acrylic with GDI

So I found another method, which is to instead put a "drag window"
exactly where the drag bar is, but on top of the XAML islands window (in
Z order). I've found that this lets us receive the `WM_LBUTTONDOWN`
messages.
--- >8 ---

Dustin's notes: I've based this on the implementation of the input sink
window in the UWP application frame host.

Tested manually in all configurations (debug, release) with snap,
drag, move, double-click and double-click on the resize handle. Tested
at 200% scale.

98ac196cec Lock when changing selection endpoint on wheel/auto-scroll (#5551)
Takes the lock inside two routines in `TermControl` that were changing
the selection endpoint while a rendering frame was still drawing,
resulting in several variants of graphical glitches from double-struck
selection boxes to duplicated line text.

## References

* [x] Manual tests passed since it's visual.
* [x] No extra doc besides the comments.
* [x] Am core contributor: Roar.

The renderer base and specific renderer engine do a lot of work to
remember the previous selection and compensate for scrolling regions and
deltas between frames. However, all that work doesn't quite match up
when the endpoints are changed out from under it. Unfortunately,
`TermControl` doesn't have a robust history of locking correctly in step
with the renderer nor does the renderer's `IRenderData` currently
provide any way of 'snapping' state at the beginning of a frame so it
could work without a full lock. So the solution for now is for the
methods that scroll the display in `TermControl` to take the lock that
is shared with the renderer's frame painter so they can't change out of
sync.

## Detailed Description of the Pull Request / Additional comments

Basically, if you use cleartype on a light background, what you'll get today is the text foreground color _added_ to the background. This will make the text look basically invisible. 

So, what I did was use some trickery with `PushLayer` to basically create a layer where the text would be forced to render in grayscale AA. I only enable this layer pushing business when both:
  * The user has enabled cleartype text
  * The background opacity < 1.0

This plumbs some information through from the TermControl to the DX Renderer to make this smooth.

## Validation Steps Performed

Opened both cleartype and grayscale panes SxS, and messed with the opacity liberally.

a76cee1d98 Include Cascadia Mono in-package, switch to it by default (#5505)
It was brought to our attention that shipping a font with ligatures as our default
font could be an accessibility issue for the visually-impaired. Unfortunately, we
don't have a renderer setting to disable ligatures (#759). Fortunately however, we
DO already have a version of Cascadia that doesn't have ligatures.

If we ship that and set it as our default font, we'll at least let people _opt_ to
have ligatures enabled by switching from `Cascadia Mono` to `Cascadia Code`.

7bf6163e63 Make sure background color is opaque when attrs are reversed (#5509)
In order to support a transparent background for the acrylic effect, the
renderer sets the alpha value to zero for the default background color.
However, when the _reversed video_ attribute is set, the background is
actually filled with the foreground color, and will not be displayed
correctly if it is made transparent. This PR addresses that issue by
making sure the rendered background color is opaque if the reversed
video attribute is set.

## References

* This is not a major issue at the moment, since the _reverse video_
  attribute is not typically forwarded though conpty, but that will
  change once #2661 is fixed.

## Detailed Description of the Pull Request / Additional comments

This simply adds an additional check in `Terminal::GetBackgroundColor`
to make sure the returned color is opaque if the _reverse video_
attribute is set. At some point in the future this check may need to be
extended to support the `DECSCNM` reverse screen mode, but for now
that's not an issue.

## Validation Steps Performed

I've run the test case from issue #5498, and confirmed that it now works
as expected. I've also got an experimental fix for #2661 that I've
tested with this patch, and that now displays _reverse video_ attributes
correctly too.

If Terminal is spawned by a shortcut that requests that it run in a new process group

cause WT to start with Ctrl-C disabled. This wouldn't matter, because it's a Windows-subsystem

a weird way, ^C stops working inside the terminal. Mad.

## Detailed Description of the Pull Request / Additional comments

**WAS:**
- We were using implicit DPI scaling on the `ID2D1RenderTarget` and running all of our processing in DIPs (Device-Independent Pixels). That's all well and good for getting things bootstrapped quickly, but it leaves the actual scaling of the draw commands up to the discretion of the rendering target.
- When we don't get to explicitly choose exactly how many pixels tall/wide and our X/Y placement perfectly, the nature of floating point multiplication and division required to do the presentation can cause us to drift off slightly out of our control depending on what the final display resolution actually is.
- Differential drawing cannot work unless we can know the exact integer pixels that need to be copied/moved/preserved/replaced between frames to give to the `IDXGISwapChain1::Present1` method. If things spill into fractional pixels or the sizes of rows/columns vary as they are rounded up and down implicitly, then we cannot do the differential rendering.

**NOW:**
- When deciding on a font, the `DxEngine` will take the scale factor into account and adjust the proposed height of the requested font. Then the remainder of the existing code that adjusts the baseline and integer-ifies each character cell will run naturally from there. That code already works correctly to align the height at normal DPI and scale out the font heights and advances to take an exact integer of pixels.
- `TermControl` has to use the scale now, in some places, and stop scaling in other places. This has to do with how the target's nature used to be implicit and is now explicit. For instance, determining where the cursor click hits must be scaled now. And determining the pixel size of the display canvas must no longer be scaled.
- `DxEngine` will no longer attempt to scale the invalid regions per my attempts in #5185 because the cell size is scaled. So it should work the same as at 96 DPI.
- The block is removed from the `DxEngine` that was causing a full invalidate on every frame at High DPI.
- A TODO was removed from `TermControl` that was invalidating everything when the DPI changed because the underlying renderer will already do that.

* Cleaning up the whitelist a bit.

  * Every successful run on master now logs its suggested cleanup, e.g. for 5740e197c2 has https://github.com/microsoft/terminal/runs/596271627#step:4:37 
* ⚠️ This check-spelling 0.0.15a+ tolerates Windows line endings in the `whitelist.txt` file (another project I touched had some `.gitconfig` magic which required supporting them).
  This means that if someone edits the file w/ something that likes Windows line endings, the file will successfully convert (instead of it being ignored and check-spelling complaining about everything). Most likely anyone else who then edits the file will use something that will maintain the line endings.

e3e57081a2 UIA: Prevent crash from invalid UTR endpoint comparison (#5399)
## Summary of the Pull Request
This is a quick-and-easy solution to #5309. If the ITextRangeProvider API allows us to take in two UiaTextRanges, we need to verify that they are both valid.

With this PR, we make sure they both fit in the current TextBuffer. If not, we return `E_FAIL`. Though this doesn't prove that both UiaTextRanges are from the same TextBuffer, at the very least we don't crash and in cases where we can't make a valid comparison, we return an HRESULT failure.

## References
#5406 - This should be the proper solution to this problem. Each UiaTextRange needs to be aware of which TextBuffer it came from.

## PR Checklist
* [X] Closes #5309

## Validation Steps Performed
1. generate enough output to cause the terminal to scroll
2. execute `nano` to make us go into the alternate buffer
This previously crashed, now NVDA seems to detect that there was an error and keeps moving along.

bceeb4523e Fix a deadlock and a bounding rects issue in UIA (#5385)
The scroll locking rework that landed with the DxRenderer's partial
invalidation change introduced a deadlock. UIA locks the buffer for
reading before asking it to scroll (which now requires a write lock.)

Scrolling is probably _okay_ to have a little bit of torn state that
might arise from us unlocking the read lock early before triggering the
write lock down the line.

While investigating this, I also noticed that our bounding rects stopped
being viewport-relative (and were instead buffer-relative.) That
regressed with the switch to `GetTextRects` in #4991

f04b7aae87 wpf: add support for VT mouse mode (#5375)
## Summary of the Pull Request

This pull request ports the VT mouse code from TermControl to WpfTerminalControl. Our WPF control is a lot closer to Win32 than to Xaml, so our mouse event handler looks _nothing_ like the one that we got from Xaml. We can pass events through almost directly, because the window message handling in the mouse input code actually came from _conhost_. It's awesome.

Neither TermControl nor conhost pass hover events through when the control isn't focused, so I wired up focus events to make sure we acted the same.

Just like Terminal and conhost, mouse events are suppressed when <kbd>Shift</kbd> is held.

## Validation Steps Performed
Tested with MC, and tested by manually engaging SGR events in an Echo terminal.

c186c7d683 Rework error handling and state flow in the Azure connection (#5356)
This commit fixes a number of problems and code quality/health issues
with the AzureConnection.

This is a general tidying-up of the azure connection. It improves error
logging (like: it actually emits error logs...) and retry logic and the
state machine and it audits the exit points of the state machine for
exceptions and removes the HRESULT returns (so they either succeed and
transition to a new state or throw an exception or are going down
anyway).

There's also a change in here that changes how we display tenants. It
adds the "default domain" to the name, so that instead of seeing this:

Conhost (aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa)
Default Directory (bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb)

you see this

Conhost (conhost.onmicrosoft.com)
Default Directory (dustinhowett.onmicrosoft.com)

Changes:

* rework tenant/tenant storage and fix display names

  Switch to the 2020 tenant API.

  Instead of passing around four loose variables, create a Tenant class
  and use that for packing/unpacking into/out of json (and the windows
  credential store, where we "cleverly" used json for the tenant info
  there too).
  
  When displaying a tenant, use its display name if there is one, the
  unknown resource string if there isn't, and the default domain if
  there is one and the ID if there isn't.
  
  Fixes #5325.

* use {fmt} for formatting request bodies
* remove dead strings
* rework/rename Request/HeaderHelper to
  Send(Authenticated)ReqReturningJson
* rewrite polling to use std::chrono
* remove HR returns from state machine
* rename state handlers from _XHelper to _RunXState
* cleanup namespaces, prefix user input with >, remove namespaces
* Rework error handling
  - _RequestHelper no longer eats exceptions.
  - Delete the "no internet" error message.
  - Wrap exceptions coming out of Azure API in a well-known type.
  - Catch by type.
  - Extract error codes for known failures (keep polling, invalid
    grant).
  - When we get an Invalid Grant, dispose of the cached refresh token
    and force the user to log in again.
  - Catch all printable exceptions and print them.
  - Remove the NoConnect state completely -- just bail out when an
    exception hits the toplevel of the output thread.
  - Move 3x logic into _RefreshTokens and pop exceptions out of it.
  - Begin abstracting into AzureClient

Fixes #5325 (by addressing its chief complaint).
Fixes #4803 (by triggering auth flow again if the token expires).
Improves diagnosability for #4575.

fe3f528827 Show a double width cursor for double width characters (#5319)
# Summary of the Pull Request
This PR will allow the cursor to be double width when on top of a double width character. This required changing `IsCursorDoubleWidth` to check whether the glyph the cursor's on top of is double width. This code is exactly the same as the original PR that addressed this issue in #2932. That one got reverted at some point due to the crashes related to it, but due to a combination of Terminal having come further since that PR and other changes to address use-after-frees, some of the crashes may/may not be relevant now. The ones that seemed to be relevant/repro-able, I attempt to address in this PR.

The `IsCursorDoubleWidth` check would fail during the `TextBuffer::Reflow` call inside of `Terminal::UserResize` occasionally, particularly when `newCursor.EndDeferDrawing()` is called. This is because when we tell the newCursor to `EndDefer`, the renderer will attempt to redraw the cursor. As part of this redraw, it'll ask if `IsCursorDoubleWidth`, and if the renderer managed to ask this before `UserResize` swapped out the old buffer with the new one from `Reflow`, the renderer will be asking the old buffer if its out-of-bounds cursor is double width. This was pretty easily repro'd using `cmatrix -u0` and resizing the window like a madman.

As a solution, I've moved the Start/End DeferDrawing calls out of `Reflow` and into `UserResize`. This way, I can "clamp" the portion of the code where the newBuffer is getting created and reflowed and swapped into the Terminal buffer, and only allow the renderer to draw once the swap is done. This also means that ConHost's `ResizeWithReflow` needed to change slightly.

In addition, I've added a WriteLock to `SetCursorOn`. It was mentioned as a fix for a crash in #2965 (although I can't repro), and I also figured it would be good to try to emulate where ConHost locks with regards to Cursor operations, and this seemed to be one that we were missing.

## PR Checklist
* [x] Closes #2713
* [x] CLA signed
* [x] Tests added/passed

## Validation Steps Performed
Manual validation that the cursor is indeed chonky, added a test case to check that we are correctly saying that the cursor is double width (not too sure if I put it in the right place). Also open to other test case ideas and thoughts on what else I should be careful for since I am quite nervous about what other crashes might occur.

dc43524eb2 Emit lines wrapped due to spaces at the end correctly (#5294)
## Summary of the Pull Request

When WSL vim prints the initial empty buffer (the one that's just a bunch of '\~'s), it prints this by doing the following:
* Print '\~' followed by enough spaces to clear the line
* Use CUP (`^[[H`) to move the cursor to the start of the next line
* repeat until the buffer is full

When we'd get the line of "\~     "... in conhost, we'd mark that line as wrapped. 

Logically, it doesn't really make any sense that when we follow that up by moving the cursor, the line is wrapped. However, this is just how conhost is right now. 
This wasn't ever a problem in just conhost before, because we really didn't care if lines in the alt buffer were "wrapped" or not. Plus, when vim would get resized, it would just reprint it's own buffer anyways. Nor was this a problem in conpty before this year (2020). We've only just recently added logic to conpty to try and preserve wrapped lines. 

Initially, I tried fixing this by breaking the line manually when the cursor was moved. This seemed to work great, except for the win32 vim.exe. Vim.exe doesn't emit a newline or a CUP to get to the next line. It just _goes for it_ and keeps printing. So there's _no way_ for us to know the line broke, because they're essentially just printing one long line, assuming we'll automatically move the cursor.

So instead, I'm making sure to emit the proper number of spaces at the end of a line when the line is wrapped. We won't do any funny business in that scenario and try to optimize for them, we'll _just print the spaces_.

348f46866a Update the virtual bottom location if the cursor moves below it (#5317)
If an application writes to the screen while not in VT mode, and the
user has scrolled forward in the screen buffer, the _virtual bottom_
location is not updated to take that new content into account. As a
result, the viewport can later jump back to the previous _virtual
bottom_, making the content disappear off screen. This PR attempts to
fix that issue by updating the _virtual bottom_ location whenever the
cursor moves below that point.

## PR Checklist
* [x] CLA signed. 
* [x] Tests added/passed

## Detailed Description of the Pull Request / Additional comments

This simply adds a condition in the
`SCREEN_INFORMATION::SetCursorPosition` to check if the new _Y_
coordinate is below the current _virtual bottom_, and if so, updates the
_virtual bottom_ to that new value.

I considered trying to make it only update when something is actually
written to the screen, but this seemed like a cleaner solution, and is
less likely to miss out on a needed update.

## Validation Steps Performed

I've manually tested the case described in issue #5302, and confirmed
that it now works as expected. I've also added a unit test that checks
the virtual bottom is updated correctly under similar conditions.

9dd5f6e8b9 Remove singleLine copy from Shift+Click, CopyOnSelect (#5346)
This fixes an issue where a shift+click selection with `copyOnSelect`
enabled would result in copying the content as a single line.

## Detailed Description of the Pull Request / Additional comments
I've been thinking a lot about this issue and how it relates to the
copy/paste discussions we've been having over the past few weeks.
Considering that the majority of users want regular copy, it makes sense
to default to that in this case too.

If a user wants to perform a special form of copy, it makes sense that
they should use their custom keybinding to accomplish that. This kind of
behavior aligns with that kind of philosophy.

## Validation Steps Performed

The following scenarios were tested with `copyOnSelect` enabled.
| scenario                                | behavior                      |
|-----------------------------------------|-------------------------------|

e61968ca87 Add support for renderer backoff, don't FAIL_FAST on 3x failures, add UI (#5353)
## Summary of the Pull Request
Renderer: Add support for backoff and auto-disable on failed retry

This commit introduces a backoff (150ms * number of tries) to the
renderer's retry logic (introduced in #2830). It also changes the
FAIL_FAST to a less globally-harmful render thread disable, so that we
stop blowing up any application hosting a terminal when the graphics
driver goes away.

In addition, it adds a callback that a Renderer consumer can use to
determine when the renderer _has_ failed, and a public method to kick it
back into life.

Fixes #5340.

This PR also wires up TermControl so that it shows some UI when the renderer tastes clay.

## Validation Steps Performed

I tested this by dropping the number of retries to 1 and forcing a TDR while doing `wsl cmatrix -u0`. It picked up exactly where it left off.

As a bonus, you can actually still type into the terminal when it's graphically suspended (and `exit` still works.). The block is _entirely graphical_.

114e462669 Import fmtlib/fmt@6.2.0, a C++20-style format library (#5336)
We received a request from our localization team to switch from
printf-style format strings (%s, %u) to format strings with positional
argument support. I've been hoping for a long time to take a dependency
on C++20's std::format, but we're just not somewhere we can do that.
Enter fmt. fmt is _exactly_ the library we need.

Minor comparison:

std::wstring_view world = /* ... */;
auto str{ wil::str_printf<std::wstring>(L"hello %.*s",
	   gsl::narrow_cast<size_t>(world.size()),
	   world.data()) };

---

auto str{ fmt::format(L"hello {0}", world) };

If you really want to use the print specifiers:

auto str{ fmt::printf(L"hello %s", world) };

It's got optional compile-time checking for format strings and is
MIT-licensed. Eventually, we should be able to replace fmt:: with std::
and end up pretty much where we left off.
What more could you ask for?

79684bf821 Render row-by-row instead of invalidating entire screen (#5185)
## Summary of the Pull Request
Adjusts DirectX renderer to use `til::bitmap` to track invalidation
regions. Uses special modification to invalidate a row-at-a-time to
ensure ligatures and NxM glyphs continue to work.

## References
Likely helps #1064

## PR Checklist
* [x] Closes #778
* [x] I work here.
* [x] Manual testing performed. See Performance traces in #778.
* [x] Automated tests for `til` changes.
* [x] Am core contributor. And discussed with @DHowett-MSFT.

## Detailed Description of the Pull Request / Additional comments
- Applies `til::bitmap` as the new invalidation scheme inside the
  DirectX renderer and updates all entrypoints for collecting
  invalidation data to coalesce into this structure.
- Semi-permanently routes all invalidations through a helper method
  `_InvalidateRectangle` that will expand any invalidation to cover the
  entire line. This ensures that ligatures and NxM glyphs will continue
  to render appropriately while still allowing us to dramatically reduce
  the number of lines drawn overall. In the future, we may come up with
  a tighter solution than line-by-line invalidation and can modify this
  helper method appropriately at that later date to further scope the
  invalid region.
- Ensures that the `experimental.retroTerminalEffects` feature continues
  to invalidate the entire display on start of frame as the shader is
  applied at the end of the frame composition and will stack on itself
  in an amusing fashion when we only redraw part of the display.
- Moves many member variables inside the DirectX renderer into the new
  `til::size`, `til::point`, and `til::rectangle` methods to facilitate
  easier management and mathematical operations. Consequently adds
  `try/catch` blocks around many of the already-existing `noexcept`
  methods to deal with mathematical or casting failures now detected by
  using the support classes.
- Corrects `TerminalCore` redraw triggers to appropriately communicate
  scrolling circumstances to the renderer so it can optimize the draw
  regions appropriately.
- Fixes an issue in the base `Renderer` that was causing overlapping
  scroll regions due to behavior of `Viewport::TrimToViewport` modifying
  the local. This fix is "good enough" for now and should go away when
  `Viewport` is fully migrated to `til::rectangle`.
- Adds multiplication and division operators to `til::rectangle` and
  supporting tests. These operates will help scale back and forth
  between a cell-based rectangle and a pixel-based rectangle. They take
  special care to ensure that a pixel rectangle being divided downward
  back to cells will expand (with the ceiling division methods) to cover
  a full cell when even one pixel inside the cell is touched (as is how
  a redraw would have to occur).
- Blocks off trace logging of invalid regions if no one is listening to
  optimize performance.
- Restores full usage of `IDXGISwapChain1::Present1` to accurately and
  fully communicate dirty and scroll regions to the underlying DirectX
  framework. This additional information allows the framework to
  optimize drawing between frames by eliminating data transfer of
  regions that aren't modified and shuffling frames in place. See
  [Remarks](https://docs.microsoft.com/en-us/windows/win32/api/dxgi1_2/nf-dxgi1_2-idxgiswapchain1-present1#remarks)
  for more details.
- Updates `til::bitmap` set methods to use more optimized versions of
  the setters on the `dynamic_bitset<>` that can bulk fill bits as the
  existing algorithm was noticeably slow after applying the
  "expand-to-row" helper to the DirectX renderer invalidation.
- All `til` import hierarchy is now handled in the parent `til.h` file
  and not in the child files to prevent circular imports from happening.
  We don't expect the import of any individual library file, only the
  base one. So this should be OK for now.

## Validation Steps Performed
- Ran `cmatrix`, `cmatrix -u0`, and `cacafire` after changes were made.
- Made a bunch of ligatures with `Cascadia Code` in the Terminal
  before/after the changes and confirmed they still ligate.
- Ran `dir` in Powershell and fixed the scrolling issues
- Clicked all over the place and dragged to make sure selection works.
- Checked retro terminal effect manually with Powershell.

6f0f245dd0 Don't wait for a connection to finish when a control is closed (#5303)
## Summary of the Pull Request

When a pane is closed by a connection, we want to wait until the connection is actually `Closed` before we fire the actual `Closed` event. If the connection didn't close gracefully, there are scenarios where we want to print a message to the screen.

However, when a pane is closed by the UI, we don't really care to wait for the connection to be completely closed. We can just do it whenever. So I've moved that call to be on a background thread.

## PR Checklist
* [x] Closes #1996
* [x] I work here
* [ ] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments
Previously we'd wait for the connection to close synchronously when closing tabs or panes. For misbehaving applications like `ssh.exe`, that could result in the `Close` needing to `WaitForSingleObject` _on the UI thread_. If the user closed the tab / pane either with a keybinding or with some other UI element, they don't really care to see the error message anymore. They just want the pane closed. So there's no need to wait for the actual connection to close - the app can just continue on with whatever it was doing.

## Validation Steps Performed
Messed around with closing tabs, panes, tabs with many panes, the entire window. Did this with keybindings, or by clicking on the 'x' on the tab, the 'x' on the window, or using middle-click.

I'm always scared of things like this, so there's a 50% chance this makes things horribly worse.

This pull request makes sure we still get a usable (for troubleshooting purposes) version number in the about dialog and settings file when the user is running unpackaged.

This introduces a magic LCID constant (0x0409).B y default, Package ES emits
version resource information that says we're localized to ... language zero.
It also emits a language-coded version block for 0x0409 (en-US).

2d09dfd48b Add support for the DSR-OS operating status report (#5300)
This adds support for the VT escape sequence that requests the
terminal's operating status. There is no attempt to actually verify the
status of the app, though. We always return a response indicating a good
operating condition (the same as most terminal emulators).

## PR Checklist
* [x] CLA signed.
* [x] Tests added/passed

## Detailed Description of the Pull Request / Additional comments

This required an update to the `OutputStateMachineEngine` to accept the
`DSR-OS` type, since it only dispatches types that it recognises (I
think that's unnecessary, but that's an issue for another day).

The actual processing of the request is handled in the `AdaptDispatch`
class, where it simply responds with a hard coded sequence (`CSI 0 n`),
indicating a good operating condition.

## Validation Steps Performed

I've added unit tests to confirm that the request is dispatched
correctly, and the appropriate response is returned. I've also manually
confirmed that the test of the _Device Status Report_ in _Vttest_ is now
succeeding.

6fabc4abb7 Fix copying wrapped lines by implementing better scrolling (#5181)
Now that the Terminal is doing a better job of actually marking which
lines were and were not wrapped, we're not always copying lines as
"wrapped" when they should be. We're more correctly marking lines as not
wrapped, when previously we'd leave them marked wrapped.

The real problem is here in the `ScrollFrame` method - we'd manually
newline the cursor to make the terminal's viewport shift down to a new
line. If we had to scroll the viewport for a _wrapped_ line, this would
cause the Terminal to mark that line as broken, because conpty would
emit an extra `\n` that didn't actually exist.

This more correctly implements `ScrollFrame`. Now, well move where we
"thought" the cursor was, so when we get to the next `PaintBufferLine`,
if the cursor needs to newline for the next line, it'll newline, but if
we're in the middle of a wrapped line, we'll just keep printing the
wrapped line.

A couple follow up bugs were found to be caused by the same bad logic.
See #5039 and #5161 for more details on the investigations there.

5622f230a8 Control: Start the connection outside of lock (#5286)
When the connection printed text immediately, synchronously, as part of
Start() it would cause terminal to deadlock. We should start the

The ConptyConnection would do this when it failed to launch something
(trivial repro: `wt -- xyz`).

The TelnetConnection would do this all the time, because local loopback

761bee80c0 Localize the profile name for cmd, change it to Command Prompt (#5287)
This commit introduces another template replacement for the user's
default settings, COMMAND_PROMPT_LOCALIZED_NAME, which will be replaced
with the contents of the CommandPromptDisplayName resource.

By default, that will be "Command Prompt." This name change will apply
only for new users, and only on first launch. Changes in the system
locale after first launch will not impact the name of the profile.

If the user _removes_ the name from their command prompt profile, its
name will revert irrecoverably to "Command Prompt". They will not be
given a chance to regenerate a localized name.

a9c9714295 Delegate all character input to the character event handler (#4192)
My basic idea was that `WM_CHAR` is just the better `WM_KEYDOWN`.
The latter fails to properly support common dead key sequences like in
#3516.

As such I added some logic to `Terminal::SendKeyEvent` to make it return
false if the pressed key represents a printable character.
This causes us to receive a character event with a (hopefully) correctly
composed code unit, which then gets sent to `Terminal::SendCharEvent`.
`Terminal::SendCharEvent` in turn had to be modified to support
potentially pressed modifier keys, since `Terminal::SendKeyEvent` isn't
doing that for us anymore.
Lastly `TerminalInput` had to be modified heavily to support character
events with modifier key states. In order to do so I merged its
`HandleKey` and `HandleChar` methods into a single one, that now handles
both cases.
Since key events will now contain character data and character events
key codes the decision logic in `TerminalInput::HandleKey` had to be
rewritten.

## PR Checklist

## Validation Steps Performed

* See #3516.
* I don't have any keyboard that generates surrogate characters. Due to
  this I modified `TermControl::_SendPastedTextToConnection` to send the
  data to `_terminal->SendCharEvent()` instead. I then pasted the test
  string ""𐐌𐐜𐐬" and ensured that the new `TerminalInput::_SendChar`
  method still correctly assembles surrogate pairs.

This pull request introduces unexpanded variables (`%DEFAULT_PROFILE%`,

While doing this, I ran into a couple things that needed to widen from

application name and version detection up to AppLogic and expose the
AppLogic singleton.

The dynamic profile generation logic had to be moved to before we inject
the templated variables, as the new default profile depends on the
generated dynamic profiles.

38803d7d05 Make RIS switch back to the main buffer (#5248)
## Summary of the Pull Request

If we receive a _Reset to Initial State_ (`RIS`) sequence while in the alternate screen buffer, we should be switching back to the main buffer. This PR fixes that behavior.

## PR Checklist
* [x] Closes #3685
* [x] CLA signed. If not, go over [here](https://cla.opensource.microsoft.com/microsoft/Terminal) and sign the CLA
* [x] Tests added/passed
* [ ] Requires documentation to be updated
* [ ] I've discussed this with core contributors already. If not checked, I'm ready to accept this work might be rejected in favor of a different grand plan. Issue number where discussion took place: #xxx

## Detailed Description of the Pull Request / Additional comments

I've added a condition at the start of the `AdaptDispatch::HardReset` method to check whether we're using the alt buffer, and if so, call the `ConGetSet::PrivateUseMainScreenBuffer` API to switch back to the main buffer.

Calling `AdaptDispatch::UseMainScreenBuffer` would probably be neater for this, but it would also attempt to restore the cursor state, which seems pointless when we're in the process of resetting everything anyway.

## Validation Steps Performed

I've added a screen buffer test to confirm that the `RIS` sequence does actually switch back to the main buffer. I've also manually confirmed that the test case in issue #3685 does now behave as expected.

6d4c44f3a4 Prevent the cursor type being reset when changing the visibility (#5251)
A side effect of the `SetConsoleCursorInfo` API is that it resets the
cursor type to _Legacy_. This makes it impossible to change the cursor
visibility via the console APIs without also resetting the user's
preferred cursor type. This PR attempts to fix that limitation, by only
resetting the cursor type if the size has also been changed.

## PR Checklist
* [x] Closes #4124
* [x] CLA signed
* [ ] Tests added/passed
* [ ] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments

I suspect the reason for the original behaviour was because the
`SetConsoleCursorInfo` API sets both the visibility and the size, and if
you're setting the size, it's assumed you'd want the _Legacy_ cursor
type, because that's the only style for which the size is applicable.

So my solution was to only reset the cursor type if the requested cursor
size was actually different from the current size. That should be
reasonably backwards compatible with most size-changing code, but also
allow for changing the visibility without resetting the cursor type.

## Validation Steps Performed

I've tested the example code from issue #4124, and confirmed that it now
works correctly without resetting the cursor type.

I've also tested the console's _mark mode_, which temporarily changes
the cursor size while selecting. I've confirmed that the size still
changes, and that the original cursor type is restored afterwards.

4f8acb4b9f Make CodepointWidthDetector::GetWidth faster (#3727)
This is a subset of #3578 which I think is harmless and the first step towards making things right.
References #3546 #3578 

## Detailed Description of the Pull Request / Additional comments

For more robust Unicode support, `CodepointWidthDetector` should provide concrete width information rather than a simple boolean of `IsWide`. Currently only `IsWide` is widely used and optimized using quick lookup table and fallback cache. This PR moves those optimization into `GetWidth`.

## Validation Steps Performed

API remains unchanged. Things are not broken.

94215535cd doc: remove "globals" from schema (#5229)
## Summary of the Pull Request
Minor cleanup on the schema. Globals isn't accepted anymore,
so the schema should not help you autocomplete anymore.

## Validation Steps Performed
Imported the new schema. You do _not_ get a warning when globals
is in. But, the schema won't suggest things when inside globals.
It's just treated as an unknown item.

However, "defaultProfile" is still required (more of a sanity test)

286af380c9 Add more object ID tracing for Accessibility (#5215)
## Summary of the Pull Request

In preparation for getting more accessibility-related issues, I added an ID to the `ScreenInfoUiaProvider` (SIUP) and abstracted the one from `UiaTextRange`. Using this, I noticed that we are creating SIUPs when a new tab/pane is created. This is _good_. This means that we need to somehow notify a UIA Client that out structure has changed, and we need to use the new SIUP because the old one has been removed.

I'll be investigating that more after this PR lands.

9513d543b7 Force all our dialogs into the application theme, forcibly (#5224)
Because we cannot set RequestedTheme at the application level, we
occasionally run into issues where parts of our UI end up themed
incorrectly.  Dialogs, for example, live under a different Xaml root
element than the rest of our application. This makes our popup menus and
buttons "disappear" when the user wants Terminal to be in a different
theme than the rest of the system.  This hack---and it _is_ a
hack--walks up a dialog's ancestry and forces the theme on each element
up to the root. We're relying a bit on Xaml's implementation details
here, but it does have the desired effect.

It's not enough to set the theme on the dialog alone.

Fixes #3654.
Fixes #5195.

64489b1ec1 rename profiles.json to settings.json, clean up the defaults (#5199)
This pull request migrates `profiles.json` to `settings.json` and removes the legacy roaming AppData settings migrator.

It also:

* separates the key bindings in defaults.json into logical groups
* syncs the universal terminal defaults with the primary defaults
* removes some stray newlines that ended up at the beginning of settings.json and defaults.json

Fixes #5186.
Fixes #3291.

### categorize key bindings

### sync universal with main

### kill stray newlines in template files

### move profiles.json to settings.json

This commit also changes Get*Settings from returning a string to
returning a std::filesystem::path. We gain in expressiveness without a
loss in clarity (since path still supports .c_str()).

NOTE: I tried to do an atomic rename with the handle open, but it didn't
work for reparse points (it moves the destination of a symbolic link
out into the settings folder directly.)

(snip for atomic rename code)

```c++
auto path{ pathToSettingsFile.wstring() };
auto renameBufferSize{ sizeof(FILE_RENAME_INFO) + (path.size() * sizeof(wchar_t)) };
auto renameBuffer{ std::make_unique<std::byte[]>(renameBufferSize) };
auto renameInfo{ reinterpret_cast<FILE_RENAME_INFO*>(renameBuffer.get()) };
renameInfo->Flags = FILE_RENAME_FLAG_REPLACE_IF_EXISTS | FILE_RENAME_FLAG_POSIX_SEMANTICS;
renameInfo->RootDirectory = nullptr;
renameInfo->FileNameLength = gsl::narrow_cast<DWORD>(path.size());
std::copy(path.cbegin(), path.cend(), std::begin(renameInfo->FileName));

a12a6285f5 Manually pass mouse wheel messages to TermControls (#5131)
## Summary of the Pull Request

As we've learned in #979, not all touchpads are created equal. Some of them have bad drivers that makes scrolling inactive windows not work. For whatever reason, these devices think the Terminal is all one giant inactive window, so we don't get the mouse wheel events through the XAML stack. We do however get the event as a `WM_MOUSEWHEEL` on those devices (a message we don't get on devices with normally functioning trackpads).

This PR attempts to take that `WM_MOUSEWHEEL` and manually dispatch it to the `TermControl`, so we can at least scroll the terminal content.

Unfortunately, this solution is not very general purpose. This only works to scroll controls that manually implement our own `IMouseWheelListener` interface. As we add more controls, we'll need to continue manually implementing this interface, until the underlying XAML Islands bug is fixed. **I don't love this**. I'd rather have a better solution, but it seems that we can't synthesize a more general-purpose `PointerWheeled` event that could get routed through the XAML tree as normal.

8585bc6bde Clamp parameter values to a maximum of 32767. (#5200)
## Summary of the Pull Request

This PR clamps the parameter values in the VT `StateMachine` parser to 32767, which was the initial limit prior to PR #3956. This fixes a number of overflow bugs (some of which could cause the app to crash), since much of the code is not prepared to handle values outside the range of a `short`.

## References

#4254 - one example of a crash caused by the higher range

## Detailed Description of the Pull Request / Additional comments

The DEC STD 070 reference recommends supporting up to at least 16384 for parameter values, so 32767 should be more than enough for any standard VT sequence. It might be nice to increase the limit to 65535 at some point, since that is the cap used by both XTerm and VTE. However, that is not essential, since there are very few situations where you'd even notice the difference. For now, 32767 is the safest choice for us, since anything greater than that has the potential to overflow and crash the app in a number of places.

## Validation Steps Performed

I had to make a couple of modifications to the range checks in the `OutputEngineTest`, more or less reverting to the pre-#3956 behavior, but after that all of the unit tests passed as expected.

I manually confirmed that this fixes the hanging test case from #5160, as well as overflow issues in the cursor operations, and crashes in `IL` and `DL` (see https://github.com/microsoft/terminal/issues/4254#issuecomment-575292926).

9a0b6e3b69 Reimplement the VT tab stop functionality (#5173)
## Summary of the Pull Request

This is essentially a rewrite of the VT tab stop functionality, implemented entirely within the `AdaptDispatch` class. This significantly simplifies the `ConGetSet` interface, and should hopefully make it easier to share the functionality with the Windows Terminal VT implementation in the future.

By removing the dependence on the `SCREEN_INFORMATION` class, it fixes the problem of the the tab state not being preserved when switching between the main and alternate buffers. And the new architecture also fixes problems with the tabs not being correctly initialized when the screen is resized.

## References

This fixes one aspect of issue #3545.
It also supersedes the fix for #411 (PR #2816).
I'm hoping the simplification of `ConGetSet` will help with #3849.

## Detailed Description of the Pull Request / Additional comments

In the new tab architecture, there is now a `vector<bool>` (__tabStopColumns_), which tracks whether any particular column is a tab stop or not. There is also a __initDefaultTabStops_ flag indicating whether the default tab stop positions need to be initialised when the screen is resized.

The way this works, the vector is initially empty, and only initialized (to the current width of the screen) when it needs to be used. When the vector grows in size, the __initDefaultTabStops_ flag determines whether the new columns are set to false, or if every 8th column is set to true.

By default we want the latter behaviour - newly revealed columns should have default tab stops assigned to them - so __initDefaultTabStops_ is set to true. However, after a `TBC 3` operation (i.e. we've cleared all tab stops), there should be no tab stops in any newly revealed columns, so __initDefaultTabStops_ is set to false.

Note that the __tabStopColumns_ vector is never made smaller when the window is shrunk, and that way it can preserve the state of tab stops that are off screen, but which may come into range if the window is made bigger again.

However, we can can still reset the vector completely after an `RIS` or `TBC 3` operation, since the state can then be reconstructed automatically based on just the __initDefaultTabStops_ flag.

## Validation Steps Performed

The original screen buffer tests had to be rewritten to set and query the tab stop state using escape sequences rather than interacting with the `SCREEN_INFORMATION` class directly, but otherwise the structure of most tests remained largely the same.

However, the alt buffer test was significantly rewritten, since the original behaviour was incorrect, and the initialization test was dropped completely, since it was no longer applicable. The adapter tests were also dropped, since they were testing the `ConGetSet` interface which has now been removed.

I also had to make an addition to the method setup of the screen buffer tests (making sure the viewport was appropriately initialized), since there were some tests (unrelated to tab stops) that were previously dependent on the state being set in the tab initialization test which has now been removed.

I've manually tested the issue described in #4669 and confirmed that the tabs now produce the correct spacing after a resize.

ca6b54e652 Redraw TSFInputControl when Terminal cursor updates (#5135)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
This PR will allow TSFInputControl to redraw its Canvas and TextBlock in response to when the Terminal cursor position updates. This will fix the issue where during Korean composition, the first symbol of the next composition will appear on top of the previous composed character. Since the Terminal Cursor updates a lot, I've added some checks to see if the TSFInputControl really needs to redraw. This will also decrease the number of actual redraws since we receive a bunch of `LayoutRequested` events when there's no difference between them.

dfc15780c7 add til::math, use it for float conversions to point, size (#5150)
This pull request introduces the `til::math` namespace, which provides some casting functions to be used in support of `til::point` and `til::size`. When point/size want to ingest a floating-point structure, they _must_ be instructed on how to convert those floating-point values into integers.

This enables:

```
Windows::Foundation::Point wfPoint = /* ... */;
til::point tp{ til::math::rounding, wfPoint };
```

Future thoughts: should the TilMath types be stackable? Right now, you cannot get "checked + rounding" behavior (where it throws if it doesn't fit) so everything is saturating.

ef80f665d3 Correct scrolling invalidation region for tmux in pty w/ bitmap (#5122)
Correct scrolling invalidation region for tmux in pty w/ bitmap

Add tracing for circling and scrolling operations. Fix improper
invalidation within AdjustCursorPosition routine in the subsection about
scrolling down at the bottom with a set of margins enabled.

## References
- Introduced with #5024 

## Detailed Description of the Pull Request / Additional comments
- This occurs when there is a scroll region restriction applied and a
  newline operation is performed to attempt to spin the contents of just
  the scroll region. This is a frequent behavior of tmux.
- Right now, the Terminal doesn't support any sort of "scroll content"
  operation, so what happens here generally speaking is that the PTY in
  the ConHost will repaint everything when this happens.
- The PTY when doing `AdjustCursorPosition` with a scroll region
  restriction would do the following things:

1. Slide literally everything in the direction it needed to go to take
   advantage of rotating the circular buffer. (This would force a
   repaint in PTY as the PTY always forces repaint when the buffer
   circles.)
2. Copy the lines that weren't supposed to move back to where they were
   supposed to go.
3. Backfill the "revealed" region that encompasses what was supposed to
   be the newline.

- The invalidations for the three operations above were:

1. Invalidate the number of rows of the delta at the top of the buffer
   (this part was wrong)
2. Invalidate the lines that got copied back into position (probably
   unnecessary, but OK)
3. Invalidate the revealed/filled-with-spaces line (this is good).

- When we were using a simple single rectangle for invalidation, the
  union of the top row of the buffer from 1 and the bottom row of the
  buffer from 2 (and 3 was irrelevant as it was already unioned it)
  resulted in repainting the entire buffer and all was good.

- When we switched to a bitmap, it dutifully only repainted the top line
  and the bottom two lines as the middle ones weren't a consequence of
  intersect.

- The logic was wrong. We shouldn't be invalidating rows-from-the-top
  for the amount of the delta. The 1 part should be invalidating
  everything BUT the lines that were invalidated in parts 2 and 3.
  (Arguably part 2 shouldn't be happening at all, but I'm not optimizing
  for that right now.)

- So this solves it by restoring an entire screen repaint for this sort
  of slide data operation by giving the correct number of invalidated
  lines to the bitmap.

## Validation Steps Performed
- Manual validation with the steps described in #5104
- Automatic test `ConptyRoundtripTests::ScrollWithMargins`.

Closes #5104

d7123d571b Convert the About and Close All Tabs dialogs to xaml (#5140)
## Summary of the Pull Request

This pull request replaces about a hundred lines of manual xaml DOM code with a few lines of actual xaml, and wires up bound properties and event handlers in the good and correct way.

As part of this change, I've replaced the giant TextBlock in the about dialog with StackPanels, and replaced the Hyperlinks with HyperlinkButtons. This is in line with other platform applications.

URLs are _not_ localizable resources, so I moved them into the about dialog's xaml. Per #5138, we'll likely change them so that they get localization for "free" (dispatching based on the browser's language, without having to localize the URL in the application).

  fixtures has been moved into the constructor.
* Event handlers how more uniformly check `_closing` if they interact
  with the _terminal.
* Swap chain attachment has been cleaned up and no longer uses a
  coroutine when it's spawned from the UI thread.
   * We have to register the renderer's swapchain change notification
     handler after we set the swap chain, otherwise it'll call us back
     when it initializes itself.
* `InitializeTerminal` now happens under the `_terminal`'s write lock
   * Certain things that InitializeTerminal were calling themselves
     attempted to take the lock. They no longer do so.
* TermControlAutomationPeer cannot take the read lock, because setting
  the scrollbar's `Maximum` during `InitializeTerminal` will trigger
  vivification of the automation peer tree; if it attempts to take the
  lock it will deadlock during initialization.
* `BlinkCursor` was renamed to `CursorTimerTick` because it's the "Tick"
  handler for the "CursorTimer".
* `DragDropHandler` was converted into a coroutine instead of just
  _calling_ a coroutine.

Caveats:

Terminal may not have a `_buffer` until InitializeTerminal happens.
There's a nasty coupling between RenderTarget and TextBuffer that means
that we need to have a renderer before we have a buffer.

There's a second nasty coupling between RenderThread and Renderer: we
can't create a RenderThread during construction because it needs to be
given a renderer, and we can't create a Renderer during construction
because it needs a RenderThread. We don't want to kick off a thread
during construction.

Testing:

I wailed on this by opening and closing and resizing terminals and panes
and tabs, up to a hundred open tabs and one tab with 51 panes. I set one
tab to update the title as fast as it possibly could and tested
teardown, zoom, resize, mouse movement, etc. while this was all
happening.

Closes #4613.

d47da2d617 Add a "debug tap" that lets you see the VT behind a connection (#5127)
This commit adds a debugging feature that can be activated by holding
down Left Alt _and_ Right Alt when a new tab is being created, if you
have the global setting "debugFeatures" set to true. That global setting
will default to true in DEBUG builds.

That debugging feature takes the form of a split pane that shows the raw
VT sequences being written to and received from the connection.

When those buttons are held down, every connection that's created as
part of a new tab is wrapped and split into _two_ connections: one to
capture input (and stand in for the main connection) and one to capture
output (and be displayed off to the side)

Closes #3206

b3fa88eaed Process actions sync. on startup; don't dupe nonexistent profile (#5090)
This PR has evolved to encapsulate two related fixes that I can't really
untie anymore.

#2455 - Duplicating a tab that doesn't exist anymore

This was the bug I was originally fixing in #4429. 

When the user tries to `duplicateTab` with a profile that doesn't exist
anymore (like might happen after a settings reload), don't crash.

As I was going about adding tests for this, got blocked by the fact that
the Terminal couldn't open _any_ panes while the `TerminalPage` was size
0x0. This had two theoretical solutions: 

* Fake the `TerminalPage` into thinking it had a real size in the test -
  probably possible, though I'm unsure how it would work in practice.
* Change `Pane`s to not require an `ActualWidth`, `ActualHeight` on
  initialization. 

Fortuately, the second option was something else that was already on my
backlog of bugs. 

#4618 - `wt` command-line can't consistently parse more than one arg

Presently, the Terminal just arbitrarily dispatches a bunch of handlers
to try and handle all the commands provided on the commandline. That's
lead to a bunch of reports that not all the commands will always get
executed, nor will they all get executed in the same order. 

This PR also changes the `TerminalPage` to be able to dispatch all the
commands sequentially, all at once in the startup. No longer will there
be a hot second where the commands seem to execute themselves in from of
the user - they'll all happen behind the scenes on startup. 

This involved a couple other changes areound the `TerminalPage`
* I had to make sure that panes could be opened at a 0x0 size. Now they
  use a star sizing based off the percentage of the parent they're
  supposed to consume, so that when the parent _does_ get laid out,
  they'll take the appropriate size of that parent.
* I had to do some math ahead of time to try and calculate what a
  `SplitState::Automatic` would be evaluated as, despite the fact that
  we don't actually know how big the pane will be. 
* I had to ensure that `focus-tab` commands appropriately mark a single
  tab as focused while we're in startup, without roundtripping to the
  Dispatcher thread and back

## References

#4429 - the original PR for #2455
#5047 - a follow-up task from discussion in #4429
#4953 - a PR for making panes use star sizing, which was immensly
        helpful for this PR.

## Detailed Description of the Pull Request / Additional comments

`CascadiaSettings::BuildSettings` can throw if the GUID doesn't exist.
This wraps those calls up with a try/catch.

It also adds a couple tests - a few `SettingsTests` for try/catching
this state. It also adds a XAML-y test in `TabTests` that creates a
`TerminalPage` and then performs som UI-like actions on it. This test
required a minor change to how we generate the new tab dropdown - in the
tests, `Application::Current()` is _not_ a `TerminalApp::App`, so it
doesn't have a `Logic()` to query. So wrap that in a try/catch as well.

While working on these tests, I found that we'd crash pretty agressively
for mysterious reasons if the TestHostApp became focused while the test
was running. This was due to a call in
`TSFInputControl::NotifyFocusEnter` that would callback to
`TSFInputControl::_layoutRequested`, which would crash on setting the
`MaxSize` of the canvas to a negative value. This PR includes a hotfix
for that bug as well.

0461a2adbc ci: spelling: remove branch / tag filtering (#5126)
This repository tends to use `/`s in branch names.
Unfortunately, `branch: "*"` at present only matches a single
level, which means it would match a branch named `foo` but not `bar/foo`.

Given that I don't think this repository is actively using tags,
and given that the general cost for the spell checker isn't particularly
high, it's better to remove the filtering so that all branches get
checked.

Worst case, a branch that is also tagged and has spelling errors
will get two comments complaining about those spelling errors.

f90239d8d7 ci: update spelling allowlists/dictionaries (#5124)
This is just some minor whitelisting/additions to dictionaries to catch
up between when the spell checker PR was written and when it was finally
merged.

This is basically taking the spelling output from
499f24a29e and putting it into files.

The choice of files is arbitrary. I'm adding a `math.txt` dictionary
because it's a reasonable example.

The goal here is to get master to a green check mark

gave me a check mark: https://github.com/jsoref/terminal/runs/534783276

499f24a29e Rework and simplify selection in TermControl (#5096)
This commit rewrites selection handling at the TermControl layer.
Previously, we were keeping track of a number of redundant variables
that were easy to get out of sync.

The new selection model is as follows:

* A single left click will always begin a _pending_ selection operation
* A single left click will always clear a selection (#4477)
* A double left click will always begin a word selection
* A triple left click will always begin a line selection
* A selection will only truly start when the cursor moves a quarter of
  the smallest dimension of a cell (usually its width) in any direction
  _This eliminates the selection of a single cell on one click._
  (#4282, #5082)
* We now keep track of whether the selection has been "copied", or
  "updated" since it was last copied. If an endpoint moves, it is
  updated. For copy-on-select, it is only copied if it's updated.
  (#4740)

Because of this, we can stop tracking the position of the focus-raising
click, and whether it was part of click-drag operation. All clicks can
_become_ part of a click-drag operation if the user drags.

We can also eliminate the special handling of single cell selection at
the TerminalCore layer: since TermControl determines when to begin a
selection, TerminalCore no longer needs to know whether copy on select
is enabled _or_ whether the user has started and then backtracked over a
single cell. This is now implicit in TermControl.

Fixes #5082; Fixes #4477

680577f55c Update til::bitmap to use dynamic_bitset<> + libpopcnt (#5092)
This commit replaces `std::vector<bool>` with `dynamic_bitset<>` by
@pinam45 (https://github.com/pinam45/dynamic_bitset) and with
`libpopcnt` for high-performance bit counting by @kimwalisch
(https://github.com/kimwalisch/libpopcnt).

* [x] In support of performance, incremental rendering, and Terminal
  "not speed enough" as well as my sanity relative to
  `std::vector<bool>`
* [x] Tests updated and passed.
* [x] `LICENSE`, `NOTICE`, and provenance files updated.
* [x] I'm a core contributor. I discussed it with @DHowett-MSFT and
  cleared the licensing checks before pulling this in.

## Details `std::vector<bool>` provided by the Microsoft VC Runtime is
incapable of a great many things. Many of the methods you come to expect
off of `std::vector<T>` that are dutifully presented through the `bool`
variant will spontaneously fail at some future date because it decides
you allocated, resized, or manipulated the `vector<bool>` specialization
in an unsupported manner. Half of the methods will straight up not work
for filling/resizing in bulk. And you will tear your hair out as it will
somehow magically forget the assignment of half the bits you gave it
part way through an iteration then assert out and die.

As such, to preserve my sanity, I searched for an alternative. I came
across the self-contained header-only library `dynamic_bitset` by
@pinam45 which appears to do as much of `boost::dynamic_bitset` as I
wanted, but without including 400kg of boost libraries. It also has a
nifty optional dependency on `libpopcnt` by @kimwalisch that will use
processor-specific extensions for rapidly counting bits. @DHowett-MSFT
and I briefly discussed how nice `popcnt` would have been on
`std::vector<bool>` last week... and now we can have it. (To be fair, I
don't believe I'm using it yet... but we'll be able to easily dial in
`til::bitmap` soon and not worry about a performance hit if we do have
to walk bits and count them thanks to `libpopcnt`.)

This PR specifically focuses on swapping the dependencies out and
ingesting the new libraries. We'll further tune `til::bitmap` in future
pulls as necessary.

## Validation
* [x] Ran the automated tests for bitmap.
* [x] Ran the terminal manually and it looks fine still.

1e30b53867 Fix broken Chinese IME when deleting composition (#5109)
## Summary of the Pull Request
This PR fixes an out of bounds access when deleting composition during Chinese IME. What's happening is that we're receiving a CompositionCompleted before receiving the TextUpdate to tell us to delete the last character in the composition. This creates two problems for us:
1. The final character gets sent to the Terminal when it should have been deleted.
2. `_activeTextStart` gets set to `_inputBuffer.length()` when sending the character to the terminal, so when the `TextUpdate` comes right after the `CompositionCompleted` event, `_activeTextStart` is out of sync.

This PR fixes the second issue, by updating `_activeTextStart` during a `TextUpdate` in case we run into this issue. 
The first issue is trickier to resolve since we assume that if the text server api tells us a composition is completed, we should send what we have. It'll be tracked here: #5110.
At the very least, this PR will let users continue to type in Chinese IME without it breaking, but it will still be annoying to see the first letter of your composition reappear after deleting it.

69d99a7a2b deps: upgrade CppWinRT to 2.0.200316.3, gsl to v2.1.0 (#4536)
This commit upgrades C++/WinRT to 2.0.200316.3 and fixes a couple of the
transitive dependency issues we had in the process.

Because the latest version has better dependency resolution, we're able
to properly depend on Microsoft.UI.Xaml and the Toolkit in TerminalApp
and TerminalAppLib so we no longer need to manually include .dll and
.pri files.

Because of nebulous _other_ changes in dependency resolution,
WindowsTerminalUniversal isn't picking up transitive .winmd dependencies
from TerminalApp, and needs to include them as ProjectReferences
directly. This was already happening transitively, so now it's explicit.

I've also taken the time to upgrade GSL to v2.1.0, the last release
before they removed span::at and blew up our world.

ca33d895a3 Move ConPTY to use til::bitmap (#5024)
## Summary of the Pull Request
Moves the ConPTY drawing mechanism (`VtRenderer`) to use the fine-grained `til::bitmap` individual-dirty-bit tracking mechanism instead of coarse-grained rectangle unions to improve drawing performance by dramatically reducing the total area redrawn.

## PR Checklist
* [x] Part of #778 and #1064 
* [x] I work here
* [x] Tests added and updated.
* [x] I'm a core contributor

## Detailed Description of the Pull Request / Additional comments
- Converted `GetDirtyArea()` interface from `IRenderEngine` to use a vector of `til::rectangle` instead of the `SMALL_RECT` to banhammer inclusive rectangles.
- `VtEngine` now holds and operates on the `til::bitmap` for invalidation regions. All invalidation operation functions that used to be embedded inside `VtEngine` are deleted in favor of using the ones in `til::bitmap`.
- Updated `VtEngine` tracing to use new `til::bitmap` on trace and the new `to_string()` methods detailed below.
- Comparison operators for `til::bitmap` and complementary tests.
- Fixed an issue where the dirty rectangle shortcut in `til::bitmap` was set to 0,0,0,0 by default which means that `|=` on it with each `set()` operation was stretching the rectangle from 0,0. Now it's a `std::optional` so it has no value after just being cleared and will build from whatever the first invalidated rectangle is. Complementary tests added.
- Optional run caching for `til::bitmap` in the `runs()` method since both VT and DX renderers will likely want to generate the set of runs at the beginning of a frame and refer to them over and over through that frame. Saves the iteration and creation and caches inside `til::bitmap` where the chance of invalidation of the underlying data is known best. It is still possible to iterate manually with `begin()` and `end()` from the outside without caching, if desired. Complementary tests added.
- WEX templates added for `til::bitmap` and used in tests.
- `translate()` method for `til::bitmap` which will slide the dirty points in the direction specified by a `til::point` and optionally back-fill the uncovered area as dirty. Complementary tests added.
- Moves all string generation for `til` types `size`, `point`, `rectangle`, and `some` into a `to_string` method on each object such that it can be used in both ETW tracing scenarios AND in the TAEF templates uniformly. Adds a similar method for `bitmap`.
- Add tagging to `_bitmap_const_iterator` such that it appears as a valid **Input Iterator** to STL collections and can be used in a `std::vector` constructor as a range. Adds and cleans up operators on this iterator to match the theoretical requirements for an **Input Iterator**. Complementary tests added.
- Add loose operators to `til` which will allow some basic math operations (+, -, *, /) between `til::size` and `til::point` and vice versa. Complementary tests added. Complementary tests added.
- Adds operators to `til::rectangle` to allow scaling with basic math operations (+, -, *) versus `til::size` and translation with basic math operations (+, -) against `til::point`. Complementary tests added.
- In-place variants of some operations added to assorted `til` objects. Complementary tests added.
- Update VT tests to compare invalidation against the new map structure instead of raw rectangles where possible.

## Validation Steps Performed
- Wrote additional til Unit Tests for all additional operators and functions added to the project to support this operation
- Updated the existing VT renderer tests
- Ran perf check

cb3bab4ea8 Fix the Alternate Scroll Mode when DECCKM enabled (#5081)
## Summary of the Pull Request

If the _Alternate Scroll Mode_ is enabled, the terminal generates up/down keystrokes when the mouse wheel is scrolled. However, the expected escape sequences for those keys are dependent on the state of the _Cursor Keys Mode_ ( `DECCKM`), but we haven't taken that into account. This PR updates the alternate scroll implementation to make sure the appropriate sequences are sent for both `DECCKM` modes.

## Detailed Description of the Pull Request / Additional comments

I've simply added a condition in the `TerminalInput::_SendAlternateScroll` method to send a different pair of sequences dependent on the state of `_cursorApplicationMode`  flag.

## Validation Steps Performed

Manually tested in VIM (although that required me enabling the _Alternate Scroll Mode_ myself first). Also added a new unit test in `MouseInputTest` to confirm the correct sequences were generated for both `DECCKM` modes.

99fa9460fd Gracefully handle json data with the wrong value types (#4961)
## Summary of the Pull Request

Currently, if the Terminal attempts to parse a setting that _should_ be a `bool`
and the user provided a string, then we'll throw an exception while parsing the
settings, and display an error message that's pretty unrelated to the actual
problem.

The same goes for `bool`s as `int`s, `float`s as `int`s, etc.

This PR instead updates our settings parsing to ensure that we check the type of
a json value before actually trying to get its parsed value.

## Detailed Description of the Pull Request / Additional comments

I made a bunch of `JsonUtils` helpers for this in the same vein as the
`GetOptionalValue` ones.

Notably, any other value type can safely be treated as a string value.

1e57dde30b Set the ComponentResourceLocation for our DLL projects (#5031)
These projects load Xaml components that have Uids, but those Uids just
weren't working because Xaml components are, by default, loaded in
"Application" scope. Application scope is great if the resource producer
is the EXE project.

Application scope means that resources are looked up at the resource
root, but DLLs with resources don't produce resources at the root. They
produce resources at a root named after the DLL.

Setting the Xaml component resource location to Nested makes sure the
Xaml resource loader loads resources from the right places.

5672636568 Allow IME Text Wrapping (#5005)
## Summary of the Pull Request
This PR turns on TextWrapping on `TSFInputControl::TextBlock`. Once the TextBlock hits the end of the Terminal window, it will wrap downwards, but the TextBlock will have as much width as it had when composition started. Unfortunately, this means if composition starts right at the end of the Terminal with enough width for just one character, there will be a vertical line of characters down the right side of the Terminal 😅. It's definitely not ideal, and I imagine this won't be the last time we visit this issue, but for now users can see what they're typing.

f141d86280 Merged PR 4447792: Fix two bugs with DOSKEY
The first issue is in the console host: when we erase a command history,
we also clear its _allocated_ flag. It's supposed to remain allocated
but become "reset". When we later check that a command history that
exists in the list is allocated, we fail loudly because allocated has
been cleared.

The second is that in Windows Server 2003, we rewrote the console client
APIs (in kernelbase!) regarding command history and changed one internal
function from taking char** to taking char*. Since the signature was
_actually_ void** and that changed to void*, the compiler didn't notice
when in only one single place we continued to pass a char** instead of a
char*.  This caused us to send the wrong filename length for the ExeName
in SetConsoleNumberOfCommands.

ae3f8f3759 Add explicit to bool operators of Point and Rect (#4948)
Found a bug where the following won't work:
```c++
COORD inclusiveEnd{ _end };
```
where `_end` is a `til::point`.

The only fix for this is to replace these instances with this:
```c++
COORD inclusiveEnd = _end;
```

What was happening in the first notation is the implicit conversion of `til::point` to `bool` to `SHORT`. The constructor for COORD only sees one SHORT so it thinks the value should be the definition for X, and Y should stay as 0. So we end up getting `1, 0`.

By adding the explicit keyword to the bool operators, we prevent the accident above from occurring.

9e9473cfb2 til::bitmap (#4967)
## Summary of the Pull Request
Introduces type `til::bitmap` which implements an NxM grid of bits that can be used to track dirty/clean state on a per-cell basis throughout a rectangle.

## PR Checklist
* [x] In support of Differential Rendering #778
* [X] I work here.
* [x] Tests added/passed
* [x] I'm a core contributor.

## Detailed Description of the Pull Request / Additional comments
- Adds `const_iterator` to `til::rectangle` that will walk from top to bottom, left to right every position in the rectangle as a `til::point` and associated test.
- Adds `bool til::rectangle::contains(til::point)` to determine if a point lies within the rectangle and the associated test
- Adds complementary methods to `til::rectangle` of `index_of(til::point)` and `point_at(ptrdiff_t)` which will convert between a valid `point` position that lies inside the `rectangle` and the index as a count of cells from the top left corner (origin) in a top to bottom & left to right counting fashion (and associated tests).
- Adds `til::some<T, N>::clear()` to empty out the contents of the `some` and associated test.
THEN with all that support...
- Adds `til::bitmap` which represents a 2 dimensional grid of boolean/bit flags. This class contains set and reset methods for the entire region, and set only for a single `til::point` or a subregion as specified by a `til::rectangle` (and associated tests.) 
- Adds convenience methods of `any()`, `one()`, `none()`, and `all()` to the `til::bitmap` to check some of its state.
- Adds convenience method of `resize()` to `til::bitmap` that will grow or shrink the bitmap, copying whatever is left of the previous one that still fits and optionally filling or blanking the new space.
- Adds a `const_iterator` for `til::bitmap` that will walk top to bottom, left to right and return a `til::rectangle` representing a run of bits that are all on sequentially in a row. Breaks per row. Exactly as we expect to be drawing things (and associated tests.)

## Validation Steps Performed
- See automated tests of functionality.

d50409b901 Fix VT sequences for Ctrl+Alt+? input (#4947)
## Summary of the Pull Request

Ctrl+/ and Ctrl-? are complicated in VT input.

* C-/ is supposed to be `^_` (the C0 character US)
* C-? is supposed to be `DEL`
* C-M-/ is supposed to be `^[^_` (ESC US)
* C-M-? is supposed to be `^[^?` (ESC DEL)

The astute reader will note that these characters also share the same key on a
standard en-us keyboard layout, which makes the problem even more complicated.
This PR does a better job of handling these weird cases.

## Summary of the Pull Request

This is 100% on me. Even after mucking around in this function for the last 3
months, I missed that there was a single addition where we weren't doing a

cddac25726 Ignore KeyDown events during Alt-Numpad Input (#4965)
## Summary of the Pull Request
Alt-Numpad# input would be escaping each numkey before sending it through. This would result in some weird behavior, for example, in powershell, where the first alt-numpad# would start digit argument and once the user releases alt, a character is sent through and digit argument would repeat that character X times. To resolve this, we simply need to ignore KeyDowns where Alt is held and a Numpad# is pressed. 

Once Alt is released, we'll receive a character through `TSFInputControl`, not `TermControl::CharacterHandler`. It seems that the `CoreTextEditContext` in `TSFInputControl` intercepts the character before it gets to `TermControl`. TSF will then send the received character through as normal.

8211ed9fa6 Fix unbinding keys in v0.10 (#4988)
## Summary of the Pull Request

We (the royal "we") broke key unbinding in #4746. We didn't run the local tests after this, which actually would have caught this. The comment even suggests what we should have done here. We need to make sure that when we bail, it's because there's a parsing function that returned nothing. `null`, `"unbound"`, etc actually don't even have a parsing function at all, so they should just keep on keepin' on.

c0d704e734 Add cursorColor to color scheme (#4651)
Add the option to set the cursor color as part of the color scheme.

This is very useful for light themes, where the cursor disappears unless its color
is set in the profile.

Related to issue #764, but doesn't fully resolve it.

## Validation
I tested this manually by creating a light color scheme, setting the cursor color
to black and setting the profile color scheme to the newly created color scheme.
I validated the cursor is black, then set the cursor color in the profile (to red)
and saw it trumps the cursor color from the color scheme.

7621994b46 Make loop in IInputEvent more consistent and modern (#4959)
In IInputEvent, there are two for loops. One is a range based loop operating on "records", and the other is a classic for-loop doing the same. For consistency, the for-loop was changed into the more modern variation via a compiler refactoring, which has the exact same behavior as the other for-loop in the main function.

Yes, of course this was tested manually and with the unit tests.

# Validation Steps
Unit testing passed. In addition, for the manual validation tests, I compared the output for sample values between the two loops ensuring the same results.

8a9475aeb2 Update comments in the ITermDispatch interface to better indicate the VT commands that are supported. (#4752)
## Summary of the Pull Request

Most of the methods in the `ITermDispatch` interface have a comment following them that indicates the VT function that they implement. These comments are then used by the script in PR #1884 to generate a table of supported VT functions. This PR updates some of those comments, to more accurately reflect the functions that are actually supported.

## References

PR #1884 

## PR Checklist
* [ ] Closes #xxx
* [x] CLA signed.
* [x] No new tests.
* [x] No new docs.
* [ ] I've discussed this with core contributors already. If not checked, I'm ready to accept this work might be rejected in favor of a different grand plan. Issue number where discussion took place: #1884

## Detailed Description of the Pull Request / Additional comments

In some cases there are methods that implement multiple VT functions which are essentially aliases. Originally the comments listed only one of the functions, so I've now updated them to list both. This includes `HPA` as an alias of `CHA`, and `HVP` as an alias of `CUP`.

Similarly, some control characters are implemented in terms of another VT function, but only the main function was listed in the comment. Again I've now updated the comments to list both the main function and any related control characters. This includes `BS` (sharing the same method as `CUB`), `HT` (the same method as `CHT`), and `LF`, `FF`, and `VT` (the same method as `IND` and `NEL`).

Then there were some minor corrections. The `DeviceAttributes` method was commented as `DA`, but it really should be `DA1`. `DesignateCharset` was simply commented as _DesignateCharset_, when it should be `SCS`. The `DECSCNM` comment was missing a space, so it wasn't picked up by the script. And the `SetColumns` comment mistakenly included `DECSCPP`, but we don't actually support that.

Finally there is the `DeviceStatusReport` method, which potentially covers a wide range of different reports. But for now we only support the _Cursor Position Report_, so I've commented it as `DSR, DSR-CPR` to more clearly indicate our level of support. In the long term we'll probably need a better way of handling these reports though.

## Validation Steps Performed

I've run the script from PR #1884 and confirmed that the output is now a more accurate reflection of our actual VT support.

When WSL.exe would hang for users, WslDistroGenerator would also hang
while waiting for its `wsl.exe --list` call to return. The timeout was
`INFINITE` in the `WaitForSingleObject` call, but we should slap a

times out, we should also just return profiles and let the Terminal
continue to start up without the WSL distro profiles loaded.

## Summary of the Pull Request

This PR ensures that Conpty properly treats `^[^Z` and `^[^X` as

and <kbd>Ctrl+x</kbd>.

## References

## PR Checklist

* [x] I work here
* [x] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments

`^Z` and `^X` are special control characters, SUB and CAN. For the output state
machine, these characters are supposed to be executed from _any_ state. However,
we shouldn't do this for the input engine. With the current behavior, these
characters are immediately executed regardless of what state we're in. That
means we end up synthesizing <kbd>Ctrl+z/x</kbd> for these characters. However,
for the InputStateMachine engine, when these characters are preceeded by `^[`
(ESC), we want to treat them as <kbd>Ctrl+Alt+z/x</kbd>.

This just adds a check in `StateMachine` to see if we should immediately execute
these characters from any state, similar to many of the other exceptions we
already perform in the StateMachine for the input engine.

## Summary of the Pull Request
Always use the system's locale to render text to ensure the correct font variants are used.

`_ResolveFontFaceWithFallback()` overrides the last argument with the locale name of the font, but users normally configure fonts with latin alphabet only and use font linking to display non-latin characters, which causes the the locale names of the latin fonts are used to render the non-latin fonts. https://github.com/microsoft/terminal/issues/4508#issuecomment-598552472

## Summary of the Pull Request

This _actually_ implements `\033c`

I thought I had done this in #4433, but that PR actually only passthrough'd
`\x1b[3J`. I didn't realize at the time that #2715 was mostly about hard reset,
not erase scrollback.

Not only should conpty pass through RIS, but the Terminal should also be
prepared to actually handle that sequence. So this PR adds that support as well.

## Summary of the Pull Request

Currently, when the user resizes the Terminal, we'll snap the visible viewport back to the bottom of the buffer. This PR changes the visible viewport of the Terminal to instead remain in the same relative location it was before the resize.

## Detailed Description of the Pull Request / Additional comments

We already hated the `std::optional<short>&` thing I yeet'd into #4741 right at the end to replace a `short*`. So I was already going to change that to a `std::optional<std::reference_wrapper<short>>`, which is more idomatic. But then I was looking through the list of bugs and #3494 caught my eye. I realized it would be trivial to not only track the top of the `mutableViewport` during a resize, but we could use the same code path to track the _visible_ viewport's start as well. 

So basically I'm re-using that bit of code in `Reflow` to calculate the visible viewport's position too.

Gotta love just resizing things all day, errday

38058a7a86 Add support for setting the cursor visibility in Terminal (#4902)
Adds support for setting the cursor visibility in Terminal. Visibility
is a property entirely independent from whether the cursor is "on" or
not. The cursor blinker _should_ change the "IsOn" property. It was
actually changing the "Visible" property, which was incorrect. This PR
additionally corrects the naming of the method used by the cursor
blinker, and makes it do the right thing.

I added a pair of tests, one taken straight from conhost. In
copy-pasting that test, I took it a step further and implemented
`^[[?12h`, `^[[?12l`, which enables/disables cursor blinking, for the
`TerminalCore`. THIS DOES NOT ADD SUPPORT FOR DISABLING BLINKING IN THE
APP. Conpty doesn't emit the blinking on/off sequences quite yet, but
when it _does_, the Terminal will be ready.

c530d2a0d3 Don't draw the cursor if it's outside the viewport (#4901)
## Summary of the Pull Request

This changes the renederer to make sure to not draw the cursor when it is placed outside the viewport. When the window height isn't an exact multiple of a row's height, then there's a little bit of space below the last line we're actually drawing. If cursor is on the line below the viewport, then it can actually get drawn into this space. Since we're not drawing the text for that line, this is a little odd. 

This PR fixes the issue by simply ensuring the cursor is in the veiwport before we draw it.

f919a46caf Optimize rendering runs of spaces when there is no visual change (#4877)
cmatrix is somewhat of a pathological case for our infrastructure: it
prints out a bunch of green and white characters and then updates them a
million times a second.

It also maintains a column of space between every green character. When
it prints this column, it prints it in "default" or "white". This ends
up making runs of text that look like this:

(def: G=green B=bright white W=white *=matrix char  =space)

G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W

As characters trickle in:

G*W G*W G*W G*W G*W G*W G*W B*W
G*W G*W G*W G*W G*W G*W G*W G W
G*W G*W G*W B*W G*W G*W G*W G W
G*W B*W G*W G W G*W G*W G*W G*W
G*W G W G*W G W G*W B*W G*W G*W
B*W G W G*W G W G*W G W B*W G*W
G W G W G*W G W G*W G W G W B*W
G W G W B*W G W G*W G W G W G W

Every one of those color transitions causes us to break up the run of
text and start rendering it again. This impacts GDI, Direct2D *and*
ConPTY. In the example above, there are 120 runs.

The problem is, printing a space doesn't **use** the foreground color!

This commit introduces an optimization. When we're about to break a text
cluster because its attributes changed, we make sure that it's not just
filled with spaces and doesn't differ in any visually-meaningful way
(like underline or strikethrough, considering global invert state).

This lets us optimize both the rendering _and_ the PTY output to look
like this:

G*   *   *   *   *   *   *  B*G
G*   *   *   *   *   *   *
G*   *   *  B*G  *   *   *
G*  B*G  *       *   *   *   *
G*       *       *  B*G  *   *
B*G      *       *      B*G  *
G        *       *          B*G
G       B*G      *

Text will be printed at best line-by-line and at worst only when the
visible properties of the screen actually change. In the example
above, there are only 21 runs.

This speeds up cmatrix remarkably.

93b31f6e3f Add support for "reflow"ing the Terminal buffer (#4741)
This PR adds support for "Resize with Reflow" to the Terminal. In
conhost, `ResizeWithReflow` is the function that's responsible for
reflowing wrapped lines of text as the buffer gets resized. Now that
#4415 has merged, we can also implement this in the Terminal. Now, when
the Terminal is resized, it will reflow the lines of it's buffer in the
same way that conhost does. This means, the terminal will no longer chop
off the ends of lines as the buffer is too small to represent them. 

As a happy side effect of this PR, it also fixed #3490. This was a bug
that plagued me during the investigation into this functionality. The
original #3490 PR, #4354, tried to fix this bug with some heavy conpty
changes. Turns out, that only made things worse, and far more
complicated. When I really got to thinking about it, I realized "conhost
can handle this right, why can't the Terminal?". Turns out, by adding
resize with reflow, I was also able to fix this at the same time.
Conhost does a little bit of math after reflowing to attempt to keep the
viewport in the same relative place after a reflow. By re-using that
logic in the Terminal, I was able to fix #3490.

I also included that big ole test from #3490, because everyone likes
adding 60 test cases in a PR.

## EDIT: Changes to this PR on 5 March 2020

I learned more since my original version of this PR. I wrote that in
January, and despite my notes that say it was totally working, it
_really_ wasn't.

Part of the hard problem, as mentioned in #3490, is that the Terminal
might request a resize to (W, H-1), and while conpty is preparing that
frame, or before the terminal has received that frame, the Terminal
resizes to (W, H-2). Now, there aren't enough lines in the terminal
buffer to catch all the lines that conpty is about to emit. When that
happens, lines get duplicated in the buffer. From a UX perspective, this
certainly looks a lot worse than a couple lost lines. It looks like
utter chaos.

So I've introduced a new mode to conpty to try and counteract this
behavior. This behavior I'm calling "quirky resize". The **TL;DR** of
quirky resize mode is that conpty won't emit the entire buffer on a
resize, and will trust that the terminal is prepared to reflow it's
buffer on it's own.

This will enable the quirky resize behavior for applications that are
prepared for it. The "quirky resize" is "don't `InvalidateAll` when the
terminal resizes". This is added as a quirk as to not regress other
terminal applications that aren't prepared for this behavior
(gnome-terminal, conhost in particular). For those kinds of terminals,
when the buffer is resized, it's just going to lose lines. That's what
currently happens for them.  

When the quirk is enabled, conpty won't repaint the entire buffer. This
gets around the "duplicated lines" issue that requesting multiple
resizes in a row can cause. However, for these terminals that are
unprepared, the conpty cursor might end up in the wrong position after a
quirky resize.

The case in point is maximizing the terminal. For maximizing
(height->50) from a buffer that's 30 lines tall, with the cursor on
y=30, this is what happens: 

  * With the quirk disabled, conpty reprints the entire buffer. This is
    60 lines that get printed. This ends up blowing away about 20 lines
    of scrollback history, as the terminal app would have tried to keep
    the text pinned to the bottom of the window. The term. app moved the
    viewport up 20 lines, and then the 50 lines of conpty output (30
    lines of text, and 20 blank lines at the bottom) overwrote the lines
    from the scrollback. This is bad, but not immediately obvious, and
    is **what currently happens**. 


  * With the quirk enabled, conpty doesn't emit any lines, but the
    actual content of the window is still only in the top 30 lines.
    However, the terminal app has still moved 20 lines down from the
    scrollback back into the viewport. So the terminal's cursor is at
    y=50 now, but conpty's is at 30. This means that the terminal and
    conpty are out of sync, and there's not a good way of re-syncing
    these. It's very possible (trivial in `powershell`) that the new
    output will jump up to y=30 override the existing output in the
    terminal buffer. 

The Windows Terminal is already prepared for this quirky behavior, so it
doesn't keep the output at the bottom of the window. It shifts it's
viewport down to match what conpty things the buffer looks like.

What happens when we have passthrough mode and WT is like "I would like
quirky resize"? I guess things will just work fine, cause there won't be
a buffer behind the passthrough app that the terminal cares about. Sure,
in the passthrough case the Terminal could _not_ quirky resize, but the
quirky resize won't be wrong.

64ac0d25e0 vt: make sure to Flush the entire parsed sequence (#4870)
When we had to flush unknown sequences to the terminal, we were only
taking the _most recent run_ with us; therefore, if we received `\e[?12`
and `34h` in separate packets we would _only_ send out `34h`.

This change fixes that issue by ensuring that we cache partial bits of
sequences we haven't yet completed, just in case we need to flush them.

## Detailed Description of the Pull Request / Additional comments
- The most common case for VT rendering is formatting a few numbers into a sequence. For the most part, we can already tell the maximum length that the string could be based on the number of substitutions and the size of the parameters.
- The existing formatting method would always double-call. It would first call for how long the string was going to be post-formatting, allocate that memory, then call again and fill it up. This cost two full times of running through the string to find a length we probably already knew for the most part.
- Now if a size is provided, we allocate that first and attempt the "second pass" of formatting directly into the buffer. This saves the count step in the common case.
- If this fails, we fall back and do the two-pass method (which theoretically means the bad case is now 3 passes.)
- The next biggest waste of time in this method was allocating and freeing strings for every format pass. Due to the nature of the VT renderer, many things need to be formatted this way. I've now instead moved the format method to hold a static string that really only grows over the course of the session for all of these format operations. I expect a majority of the time, it will only be consuming approximately 5-15 length of a std::string of memory space. I cannot currently see a circumstance where it would use more than that, but I'm consciously trading memory usage when running as a PTY for overall runtime performance here.

## Validation Steps Performed
- Ran the thing manually and checked it out with wsl and cmatrix and Powershell and such attached to Terminal
- Wrote and ran automated tests on formatting method

- Some of my ideas for the `DxEngine` require the ability to specify multiple smaller rectangles instead of one giant one, specifically to mitigate the case where someone refreshes just one cell in two opposite corners of the display (which currently coalesces into refreshing the entire display.)
- This is pulled out into an individual PR to make it easier to review that concept changing.

## Validation Steps Performed

d954ad68f2 Suppress run breaking for abs. differences < 0.001 in advance (#4861)
With certain font faces at certain sizes, the advances seem to be
slightly more than the pixel grid; Cascadia Code at 13pt (though, 200%
scale) had an advance of 10.000001.

This commit makes it so that anything sub-1/100 of a cell won't make us
break up runs, because doing so results in suboptimal rendering.

Fixes #4806.

61d635367b Show InputPanel on focus and pointer press (#4867)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
I originally thought that setting `TSFInputControl::_editContext.InputPaneDisplayPolicy` to be Automatic would allow the InputPanel to show and hide automatically when `TSFInputControl` gains and loses focus. It doesn't seem to behave that way, so we'll show the InputPanel manually. 

I'll show the panel during `PointerPressedHandler` and during `GotFocusHandler`. A user will have the on-screen keyboard pop up when getting focus, but if they close the keyboard, they can simply re-tap on the terminal to bring it back up.

75f4240adc Reveal the taskbar when the user has the Terminal maximized or fullscreen (#4857)
## Summary of the Pull Request

When we are maximized or fullscreened, check for the presence of the taskbar in auto-hide mode. If the Terminal finds the taskbar on any side of the monitor, adjust our window rect by just a little bit, so that the taskbar can still be revealed by the user mousing over that edge.

## Detailed Description of the Pull Request / Additional comments

Note to future code archeologists:
This doesn't seem to work for fullscreen on the primary display. However, testing a bunch of other apps with fullscreen modes and an auto-hiding taskbar has shown that _none_ of them reveal the taskbar from fullscreen mode. This includes Edge, Firefox, Chrome, Sublime Text, Powerpoint - none seemed to support this. 

This does however work fine for maximized.

## Validation Steps Performed

I'm maximized and fullscreened the Terminal a lot in the last two days.

<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
Right clicking on a focused tab while Copy On Select is active currently copies any active selection. This is because `PointerReleasedHandler` doesn't check for the mouse button that was released. 
During a mouse button release, only the left mouse button release should be doing anything.

These are the scenarios I've tested. They're a combination of in focus/out of focus, Copy On Select on/off, left/right click pressed and their move and release variants.

From Out of Focus:
- Left Click = Focus
- Left Click Move = Focus + Selection
- Left Click Release
  - CoS on = Copy
  - CoS off = Nothing
- Shift Left Click = Focus
- Right Click 
  - Focus 
  - CoS on = Paste
  - CoS off = Copy if Active Selection, Paste if not.
- Right Click Move = Nothing
- Right Click Release = Nothing

From In Focus
- Left Click = Selection if CoS off
- Left Click Move = Selection
- Left Click Release
  - CoS on = Copy
  - CoS off = Nothing
- Shift Left Click = Set Selection Anchor
- Right Click 
  - CoS on = Paste
  - CoS off = Copy if Active Selection, Paste if not.

## Summary of the Pull Request

Add a `SizeChanged` handler to the titlebar content UI element. It's possible that this element's size will change after the dragbar's. When that happens, the drag bar won't send another `SizeChanged` event, because the dragbar's _size_ didn't change, only it's position.

a34a957cf7 Send TSF input buffer starting from _activeTextStart to the end of the buffer (#4836)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
Emoji composition was only being shown one letter at a time. This is because of the way I expected `CoreTextTextUpdatingEventArgs.Range` to be provided to TSFInputControl during composition (for Chinese/Japanese IME). Emoji IME composition gives the `StartCaretPosition` as the same as `EndCaretPosition`, unlike how for Chinese/Japanese IME, `StartCaretPosition` is usually the start of the composition and `EndCaretPosition` is the latest character in the composition. The solution is to change the `_inputBuffer.substr()` call to simply grab all of the buffer starting from `_activeTextStart`. This way I can ensure that I grab all of the "active text", instead of trusting the given `args.Range` to tell me the active text.

e79a421f3a Abstract GetTextForClipboard() for UIA (#4578)
## Summary of the Pull Request
`GetTextForClipboard` already exists in the TextBuffer. It makes sense to use that for UIA as well. This changes the behavior or `GetText()` such that it does not remove leading/trailing whitespace anymore. That is more of an expected behavior.

## References
This also contributes to...
- #4509: UIA Box Selection
- #2447: UIA Signaling for Selection
- #1354: UIA support for Wide Glyphs
Now that the expansion occurs at before render-time, the selection anchors are an accurate representation of what is selected. We just need to move GetText to the TextBuffer. Then we can have those three issues just rely on code from the text buffer. This also means ConHost gets some of this stuff for free 😀

## Detailed Description of the Pull Request / Additional comments
- `TextBuffer::GetTextForClipboard()` --> `GetText()`
- `TextBuffer::GetText()` no longer requires GetForegroundColor/GetBackgroundColor. If either of these are not defined, we return a `TextAndColor` with only the `text` field populated.
- renamed a few parameters for copying text to the clipboard for clarity
- Updated `UiaTextRange::GetText()` to use `TextBuffer::GetText()`

## Validation Steps Performed
Manual tests for UIA using accessibility insights and Windows Terminal's copy action (w/ and w/out shift)

Added tests as well.

a3d68d2b21 Tunnel F7 keypresses directly into special handlers in TermControl (#4807)
The Xaml input stack doesn't allow an application to suppress the "caret
browsing" dialog experience triggered when you press F7.

The official recommendation from the Xaml team is to catch F7 before we
hand it off.

This commit introduces a special F7 handler and an ad-hoc implementation of event bubbling.
Runtime classes implementing a custom IF7Listener interface are
considered during a modified focus parent walk to determine who can
handle F7 specifically.

If the recipient control handles F7, we suppress the message completely.

This event bubbler has some minor issues -- the search box will not be
able to receive F7 because its parent control implements the handler.
Since search is already mostly a text box, it doesn't _need_ special
caret browsing functionality as far as I can tell.

TermControl implements its OnF7Pressed handler by synthesizing a
keybindings event and an event to feed into Terminal Core directly.

It's not possible to create a synthetic KeyPressRoutedEvent; if it were,
I would have just popped one into the traditional input queue. :)

Fixes #638.

c6879d75af Make Korean IME input more consistent (#4796)
## Summary of the Pull Request
Korean IME was not working correctly due to way we were clearing the input buffer inside of `TSFInputControl`. We wanted to clear our input buffer and tell TSF to clear its input buffer as well when we receive a `CompositionCompleted` event. This works fine in some IME languages such as Chinese and Japanese. However, Korean IME composes characters differently in such a way where we can't tell TSF to clear their buffer during a `CompositionCompleted` event because it would clear the character that triggered the `CompositionCompleted` event in the first place.

The solution in this PR is to keep our `_inputBuffer` intact until the user presses <kbd>Enter</kbd> or <kbd>Esc</kbd>, in which case we clear our buffer and the TSF buffer. I've chosen these two keys because it seems to make sense to clear the buffer after text is sent to the terminal with <kbd>Enter</kbd>, and <kbd>Esc</kbd> usually means to cancel a current composition anyway.

This means we need to keep track of our last known "Composition Start Point", which is represented by `_activeTextStart`. Whenever we complete a composition, we'll send the portion of the input buffer between `_activeTextStart` and the end of the input buffer to the terminal. Then, we'll update `_activeTextStart` to be the end of the input buffer so that the next time we send text to the terminal, we'll only send the portion of our buffer that's "active".

44c4a8c925 AzCon: improve input, usability, reliability (4 commits) (#4756)
* Azure: rewrite user input handler

This commit replaces the AzureConnection's input handler with one that
acts more like "getline()". Instead of the Read thread setting a state
and WriteInput filling in the right member variable, the reader blocks
on the user's input and receives it in an optional<string>.

This moves the input number parsing and error case handling closer to
the point where those inputs are used, as opposed to where they're
collected.

It also switches our input to be "line-based", which is a huge boon for
typing tenant numbers >9. This fixes #3233. A simple line editor
(supporting only backspace and CR) is included.

It also enables echo on user input, and prints it in a nice pretty green
color.

It also enables input queueing: if the user types anything before the
connection is established, it'll be sent once it is.

Fixes #3233.

* Azure: display the user's options and additional information in color

This commit colorizes parts of the AzCon's strings that include "user
options" -- things the user can type -- in yellow. This is to help with
accessibility.

The implementation here is based on a discussion with the team.
Alternative options for coloration were investigated, such as:

* Embedding escape sequences in the resource file.
  This would have been confusing for translators.
  The RESW file format doesn't support &#x1B; escapes, so we would need
  some magic post-processing.
* Embedding "markup" in the resource file (like #{93m}, ...)
  This still would have been annoying for translators.

We settled on an implementation that takes resource names, colorizes
them, and string-formats them into other resources.

* Azure: follow the user's shell choice from the online portal

Fixes #2266.

* Azure: remove all credentials instead of just the first one

## Summary of the Pull Request
Adjusts column padding code in `CustomTextLayout` to only pad out for surrogate pairs, not anything that reports two columns.

## References
- See also #4747

## PR Checklist
* [x] Closes #4780
* [x] I work here.
* [x] Manual tests.
* [x] No doc, this fixes code to match comment. Oops.
* [x] Am core contributor. Also discussed with @leonMSFT. 

## Detailed Description of the Pull Request / Additional comments
For surrogate pairs like high Unicode emoji, we receive two wchar_ts but only one column count (which is usually 2 because emoji are usually inscribed in the full-width squares.) To compensate for this, I added in a little padding function at the top of the `CustomTextLayout` construction that adds a column of 0 aligned with the second half of a surrogate pair so the text-to-glyph mapping lines up correctly.

Unfortunately, I made a mistake while either responding to PR feedback in #4747 or in the first place and I made it pad out extra 0 columns based on the FIRST column count, not based on whether or not there is a trailing surrogate pair. The correct thing to do is to pad it out based on the LENGTH of text associated with the given column count. This means that full width characters which can be represented in one wchar_t, like those coming from the IME in most cases (U+5C41 for example) will have a column count of 2. This is perfectly correct for mapping text-to-glyphs and doesn't need a 0 added after it. A house emoji (U+1F3E0) comes in as two wchar_ts (0xD83C 0xDFE0) with the column count of 2. To ensure that the arrays are aligned, the 2 matches up with the 0xD83C but the 0xDFE0 needs a 0 on it so it will be skipped over. (Don't worry, because it's a surrogate, it's naturally consumed correctly by the glyph mapper.)

The effect was that every OTHER character inserted by the IME was scaled to 0 size (as an advance of 0 was expected for 0 columns).
The fix restores it so those characters don't have an associated count and aren't scaled.

## Validation Steps Performed
- Opened it up
- Put in the house emoji like #4747 (U+1f3e0)
- Put in some characters with simplified Chinese IME (fixed now)
- Put in the utf83.txt sample text used in #4747

## Detailed Description of the Pull Request / Additional comments
- The `_CorrectGlyphRun` function now walks through and uses the
  `_glyphClusters` map to determine the text span and glyph span for each
  cluster so it can be considered as a single unit for scaling.
- The total number of columns expected across the entire cluster
  text/glyph unit is considered for the available spacing for drawing
- The total glyph advances are summed to see how much space they will
  take
- If more space than necessary to draw, all glyphs in the cluster are
  offset into the center and the extra space is padded onto the advance of
  the last glyph in the range.
- If less space than necessary to draw, the entire cluster is marked for
  shrinking as a single unit by providing the initial text index and
  length (that is back-mapped out of the glyph run) up to the parent
  function so it can use the `_SetCurrentRun` and `_SplitCurrentRun`
  existing functions (which operate on text) to split the run into pieces
  and only scale the one glyph cluster, not things next to it as well.
- The scale factor chosen for shrinking is now based on the proportion
  of the advances instead of going through some font math wizardry
- The parent that calls the run splitting functions now checks to not
  attempt to split off text after the cluster if it's already at the end.
  This was @DHowett-MSFT's crash.
- The split run function has been corrected to fix the `glyphStart`
  position of the back half (it failed to `+=` instead of `=` which
  resulted in duplicated text, sometimes).
- Surrogate pair emoji were not allocating an appropriate number of
  `_textClusterColumns`. The constructor has been updated such that the
  trailing half of surrogate pairs gets a 0 column width (as the lead is
  marked appropriately by the `GetColumns()` function). This was the
  exception thrown.
- The `_glyphScaleCorrections` array stored up over the calls to
  `_CorrectGlyphRun` now uses a struct `ScaleCorrection` as we're up to 3
  values.
- The `ScaleCorrection` values are named to clearly indicate they're in
  relation to the original text span, not the glyph spans.
- The values that are used to construct `ScaleCorrection`s within
  `_CorrectGlyphRun` have been double checked and corrected to not
  accidentally use glyph index/counts when text index/counts are what's
  required.

## Validation Steps Performed
- Tested the utf82.txt file from one of the linked bugs. Looked
  specifically at Burmese through Thai to ensure restoration (for the most
  part) of the behavior
- Ensured that U+1f3e0 emoji (🏠) continues to draw correctly
- Checked Fixedsys Excelsior font to ensure it's not shrinking the line
  with its ligatures
- Checked ligatureness of Cascadia Code font 
- Checked combining characters U+0300-U+0304 with a capital A

0e672fac08 Move rect expansion to textbuffer; refactor selection code (#4560)
- When performing chunk selection, the expansion now occurs at the time
  of the selection, not the rendering of the selection
- `GetSelectionRects()` was moved to the `TextBuffer` and is now shared
  between ConHost and Windows Terminal
- Some of the selection variables were renamed for clarity
- Selection COORDs are now in the Text Buffer coordinate space
- Fixes an issue with Shift+Click after performing a Multi-Click
  Selection

## References
This also contributes to...
- #4509: UIA Box Selection
- #2447: UIA Signaling for Selection
- #1354: UIA support for Wide Glyphs

Now that the expansion occurs at before render-time, the selection
anchors are an accurate representation of what is selected. We just need
to move `GetText` to the `TextBuffer`. Then we can have those three
issues just rely on code from the text buffer. This also means ConHost
gets some of this stuff for free 😀

### TextBuffer
- `GetTextRects` is the abstracted form of `GetSelectionRects`
- `_ExpandTextRow` is still needed to handle wide glyphs properly

### Terminal
- Rename...
    - `_boxSelection` --> `_blockSelection` for consistency with ConHost
    - `_selectionAnchor` --> `_selectionStart` for consistency with UIA
    - `_endSelectionPosition` --> `_selectionEnd` for consistency with
      UIA
- Selection anchors are in Text Buffer coordinates now
- Really rely on `SetSelectionEnd` to accomplish appropriate chunk
  selection and shift+click actions

## Validation Steps Performed
- Shift+Click
- Multi-Click --> Shift+Click
- Chunk Selection at...
    - top of buffer
    - bottom of buffer
    - random region in scrollback

2f60cf0e91 Fix RenderThread's notify mechanism (#4698)
## Summary of the Pull Request

Fix a bug where the `Renderer::PaintFrame` method:
1. is not called until the next `RenderThread::NotifyThread` call but needs to be called because there the terminal was updated (theoretical bug)
2. is called twice but needs to be called only once (verified bug)

## References

The bug was introduced by #3511.

## Detailed Description of the Pull Request / Additional comments

### Before

#### First bug

In the original code, `_fNextFrameRequested` is set to `true` in render thread because `std::atomic_flag::test_and_set` is called.

This is wrong because it means that the render thread will render the terminal again even if there is no change after the last render.

I think the the goal was to load the boolean value for `_fNextFrameRequested` to check whether the thread should sleep or not.

The problem is that there is no method on `std::atomic_flag` to load its boolean value. I guess what happened was that the "solution" that was found was to use `std::atomic_flag::test_and_set`, followed by `std::atomic_flag::clear` if the value was `false` originally (if `std::atomic_flag::test_and_set` returned `false`) to restore the original value. I guess that this was believed to be equivalent to just a simple load, without doing any change to the value because it restores it at the end.

But it's not: this is dangerous because if the value is changed to `true` between the call to `std::atomic_flag::test_and_set` and the call to `std::atomic_flag::clear`, then the value ends up being `false` at the end which is wrong because we don't want to change it! And if that value ends up being `false`, it means that we miss a render because we will wait on `_hEvent` during the next iteration on the render thread.

Well actually, here, this not even a problem because when that code is ran, `_fPainting` is `false` which means that the other thread that modifies the `_fNextFrameRequested` value through `RenderThread::NotifyPaint` will not actually modify `_fNextFrameRequested` but rather call `SetEvent` (see the method's body).

But wait! There is a problem there too! `std::atomic_flag::test_and_set` is called for `_fPainting` which sets its value to `true`. It was probably unintended. So actually, the next call to `RenderThread::NotifyPaint` _will_ end up modifying `_fNextFrameRequested` which means that the data race I was talking about _might_ happen!

#### Second bug

Let's go back a little bit in my explanation. I was talking about the fact that:

> I guess what happened was that the "solution" that was found was to use `std::atomic_flag::test_and_set`, followed by `std::atomic_flag::clear` if the value was `false` originally (if `std::atomic_flag::test_and_set` returned `false`) to restore the original value.

The problem is that the reverse was done in the implementation: `std::atomic_flag::clear` is called if the value was _`true`_ originally!

So at this point, if the value of `_fNextFrameRequested` was `false`, then `std::atomic_flag::test_and_set` sets its is set to `true` and returns `false`. So for the next iteration, `_fNextFrameRequested` is `true` and the render thread will re-render but that was not needed.

### After

I used `std::atomic<bool>` instead of `std::atomic_flag` for `_fNextFrameRequested` and the other atomic field because it has a `load` and a `store` method so we can actually load the value without changing it.

I also replaced `_fPainting` by `_fWaiting`, which is basically the opposite of `_fPainting` but stays `true` for a little shorter than `_fPainting` would stay `false`. Indeed, I think that it makes more sense to directly wrap/scope _just_ the call to `WaitForSingleObject` by setting my atomic variable to `true` _just_ before and to `false` _just_ after because:
* It makes more sense while you're reading the code: it's easier IMO to understand what the purpose of `_fWaiting` is (that is, to call `SetEvent` from `RenderThread::NotifyPaint` if it's `true`).
* It's probably a tiny bit better for performance because it will become `true` for a little shorter which means less calls to `SetEvent`.

#### Warning

I don't really understand [std::memory_order](https://en.cppreference.com/w/cpp/atomic/memory_order)s.

So I used the default one (`std::memory_order_seq_cst`) which is the safest.

I believe that if no read or write are reordered in the two threads (`RenderThread::NotifyPaint` and `RenderThread::_ThreadProc`), then the code I wrote will behave correctly.

I think that `std::memory_order_seq_cst` enforces that so it should be fine, but I'm not sure.

## Validation Steps Performed

**I tried to reproduce the second bug that I described in the first section of this PR.**

I put a breakpoint on `RenderThread::NotifyPaint` and on `Renderer::PaintFrame`. Initially they are disabled. Then I ran the terminal in Release mode, waited a bit for the prompt to display and the cursor to start blinking. Then I enabled the breakpoints.

### Before

Each `RenderThread::NotifyPaint` is followed by 2 `Renderer::PaintFrame` calls.  

### After

Each `RenderThread::NotifyPaint` is followed by 1 `Renderer::PaintFrame` call. ✔️

e5182fb3e8 Make Conpty emit wrapped lines as actually wrapped lines (#4415)
## Summary of the Pull Request

Changes how conpty emits text to preserve line-wrap state, and additionally adds rudimentary support to the Windows Terminal for wrapped lines.

## References

* Does _not_ fix (!) #3088, but that might be lower down in conhost. This makes wt behave like conhost, so at least there's that
* Still needs a proper deferred EOL wrap implementation in #780, which is left as a todo
* #4200 is the mega bucket with all this work
* MSFT:16485846 was the first attempt at this task, which caused the regression MSFT:18123777 so we backed it out.
* #4403 - I made sure this worked with that PR before I even sent #4403

## PR Checklist
* [x] Closes #405
* [x] Closes #3367 
* [x] I work here
* [x] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments

I started with the following implementation:
When conpty is about to write the last column, note that we wrapped this line here. If the next character the vt renderer is told to paint get is supposed to be at the start of the following line, then we know that the previous line had wrapped, so we _won't_ emit the usual `\r\n` here, and we'll just continue emitting text.

However, this isn't _exactly_ right - if someone fills the row _exactly_ with text, the information that's available to the vt renderer isn't enough to know for sure if this line broke or not. It is possible for the client to write a full line of text, with a `\n` at the end, to manually break the line. So, I had to also add the `lineWrapped` param to the `IRenderEngine` interface, which is about half the files in this changelist.

## Validation Steps Performed
* Ran tests
* Checked how the Windows Terminal behaves with these changes
* Made sure that conhost/inception and gnome-terminal both act as you'd expect with wrapped lines from conpty

d7ea526c3c Don't split surrogate pairs when breaking runs for scaling. Affects emoji rendering. #4704 (#4731)
## Summary of the Pull Request
- Surrogate pairs are being split in half with the run splitting check.

## References
- Related to #4708 but not going to fix it.

## PR Checklist
* [x] Closes #4704
* [x] I work here.
* [x] I am a core contributor.

## Detailed Description of the Pull Request / Additional comments
- The adjustment of the run heights in the correction function reports back a text index and a scaling factor. However, I didn't remember at the time that the text is being stored as UTF-16. So the index given can be pointing to the high surrogate of a pair. Thus adding 1 to split "after" the text character, then backing up by 1 isn't valid in if the index given was for a high surrogate.

The quick fix is to advance by two if it's a high surrogate and one otherwise.

## Validation Steps Performed
- Used the sample code from #4704 to print the house emoji in various situations into the buffer.

61e5917fe8 Allow IME input in Search Box (#4723)
## Summary of the Pull Request
Currently, when the user attempts to type using IME while the Search Box is focused, the input goes to the terminal instead. This is due to the fact that the `TSFInputControl` assumes it's in control whenever TermControl gets focus. So, it'll intercept IME input before the Search Box receives it. We simply need to modify `TermControl::GotFocus` to check if the SearchBox has focus. If it does, `TSFInputControl::NotifyFocusEnter` shouldn't be called.

As a small side fix, I've also disabled the terminal cursor blinking when the Search Box has focus.

Thinking a little further, if we have more features in the future that behave like search box (i.e. advanced tab switcher, or any other XAML controls that pop up) and require text input, we might need to create a sort of "AnyOtherTextControlInFocus" function to see if TSFInputControl should receive focus or not.

## Validation Steps Performed
Search works as expected with IME. Composition picker appears underneath Search Box when typing IME in the Search Box. Clicking outside of the Search Box still returns control to TSFInputControl/TermControl.

Terminal Cursor blinks when it has focus, and doesn't when the Search Box has focus.

31c9d19a72 Display Emojis, Kaomojis, and symbols while in IME mode (#4688)
## Summary of the Pull Request
Currently, while in IME mode, selections with the Emoji/Kaomoji/Symbol Picker (which is brought up with <kbd>win+.</kbd>) are not displayed until the user starts a new composition. This is due to the fact that we hide the TextBlock when we receive a CompositionCompleted event, and we only show the TextBlock when we receive a CompositionStarted event. Input from the picker does not count as a composition, so we were never showing the text box, even if the symbols were thrown into the inputBuffer. In addition, we weren't receiving CompositionStarted events when we expected to.

We should be showing the TextBlock when we receive _any_ text, so we should make the TextBlock visible inside of `TextUpdatingHandler`. Furthermore, some really helpful discussion in #3745 around wrapping the `NotifyTextChanged` call with a `NotifyFocusLeave` and a `NotifyFocusEnter` allowed the control to much more consistently determine when a CompositionStarted and a CompositionEnded.

I've also went around and replaced casts with saturating casts, and have removed the line that sets the `textBlock.Width()` so that it would automatically set its width. This resolves the issue where while composing a sentence, the textBlock would be too small to contain all the text, so it would be cut off, but the composition is still valid and still able to continue.

b8e33560f9 make sure caching of partials still works if the string consists of a single lead byte only (GH#4673) (#4685)
## Summary of the Pull Request
Fixes a flaw that happened if `til::u8u16` received a single lead byte.

## PR Checklist
* [x] Closes #4673 
* [x] Tests added/passed

## Detailed Description of the Pull Request / Additional comments
The loop for caching partials didn't run and thus, the lead byte was
converted to U+FFFD. That's because the loop starts with `sequenceLen`
initialized with 1. And if the string has a length of 1 the initial
condition is `1<1` which is evaluated to `false` and the body of the
loop was never executed.

## Validation Steps Performed
1) updated the code of the state class and tested manually that `printf
   "\xE2"; printf "\x98\xBA\n"` prints a U+263A character
2) updated the unit tests to make sure that still up to 3 partials are
   cached
3) updated the unit tests to make sure caching also works if the string
   consists of a lead byte only
4) tested manually that #4086 is still resolved

671110c88a Clip text to within the row we expect (#4671)
## Summary of the Pull Request
Adjusts `DrawGlyphRun` method inside DirectX renderer to restrict text
to be clipped within the boundaries of the row.

## PR Checklist
* [x] Closes #1703
* [x] I work here.
* [x] No tests.
* [x] No docs.
* [x] I am core contributor.

## Detailed Description of the Pull Request / Additional comments
For whatever reason, some of these shade glyphs near U+2591 tend to
extend way above the height of where we expect they should. This didn't
look like a problem in conhost because it clipped every draw inside the
bounds. This therefore applies the same clip logic as people don't
really expect text to pour out of the box.

It could, theoretically, get us into trouble later should someone
attempt zalgo text. But doing zalgo text is more of a silliness that
varies in behavior across rendering platforms anyway.

4420950337 Restrict DX run height adjustment to only relevant glyph AND Correct PTY rendering on trailing half of fullwidth glyphs (#4668)
## Summary of the Pull Request
- Height adjustment of a glyph is now restricted to itself in the DX
  renderer instead of applying to the entire run
- ConPTY compensates for drawing the right half of a fullwidth
  character. The entire render base has this behavior restored now as
  well.

## Detailed Description of the Pull Request / Additional comments
Two issues:
1. On the DirectX renderer side, when confronted with shrinking a glyph,
   the correction code would apply the shrunken size to the entire run, not
   just the potentially individual glyph that needed to be reduced in size.
   Unfortunately while adjusting the horizontal X width can be done for
   each glyph in a run, the vertical Y height has to be adjusted for an
   entire run. So the solution here was to split the individual glyph
   needing shrinking out of the run into its own run so it can be shrunk.
2. On the ConPTY side, there was a long standing TODO that was never
   completed to deal with a request to draw only the right half of a
   two-column character. This meant that when encountering a request for
   the right half only, we would transmit the entire full character to be
   drawn, left and right halves, struck over the right half position. Now
   we correct the cursor back a position (if space) and draw it out so the
   right half is struck over where we believe the right half should be (and
   the left half is updated as well as a consequence, which should be OK.)

The reason this happens right now is because despite VIM only updating
two cells in the buffer, the differential drawing calculation in the
ConPTY is very simplistic and intersects only rectangles. This means
from the top left most character drawn down to the row/col cursor count
indicator in vim's modeline are redrawn with each character typed. This
catches the line below the edited line in the typing and refreshes it.
But incorrectly.

We need to address making ConPTY smarter about what it draws
incrementally as it's clearly way too chatty. But I plan to do that with
some of the structures I will be creating to solve #778.

## Validation Steps Performed
- Ran the scenario listed in #2191 in vim in the Terminal
- Added unit tests similar to examples given around glyph/text mapping
  in runs from Microsoft community page

7d6738cde7 Shim the AzureConn through a conhost to stop VT bleeding (#4652)
This commit introduces a small console-subsystem application whose sole
job is to consume TerminalConnection.dll and hook it up to something
other than Terminal. It is 99% of the way to a generic solution.

I've introduced a stopgap in TerminalPage that makes sure we launch
TerminalAzBridge using ConptyConnection instead of AzureConnection.

As a bonus, this commit includes a class whose sole job it is to make
reading VT input off a console handle not terrible. It returns you a
string and dispatches window size change callbacks.

Fixes #2267.
Fixes #4589.

360c655acc UIA: Fix GetVisibleRanges() and add Tracing (#4495)
## Summary of the Pull Request
Debugging our custom UIA providers has been a painful experience because outputting content to VS may result in UIA Clients getting impatient and giving up on extracting data.

Adding tracing allows us to debug these providers without getting in the way of reproducing a bug. This will help immensely with developing accessibility features on Windows Terminal and Console.

This pull request additionally contains payload from #4526:
* Make GetVisibleRanges() return one range (and add tracing for it).
`ScreenInfoUiaProvider::GetVisibleRanges()` used to return one range per line of visible text. The documentation for this function says that we should return one per contiguous span of text. Since all of the text in the TermControl will always be contiguous (at least by our standards), we should only ever be returning one range.

## PR Checklist
* [x] Closes #1914. Closes #4507.
* [x] CLA signed

## Detailed Description of the Pull Request / Additional comments
`UiaTracing` is a singleton class that is in charge of registration for trace logging. `TextRange` is used to trace `UiaTextRange`, whereas `TextProvider` is used to trace `ScreenInfoUiaProviderBase`.

`_getValue()` is overloaded to transform complex objects and enums into a string for logging.

`_getTextValue()` had to be added to be able to trace the text a UiaTextRange included. This makes following UiaTextRanges much simpler.

## Validation Steps Performed
Performed a few operations when under NVDA/Narrator and manually checked the results.

d0c8221c6e Make ScreenInfoUiaProvider::GetSelection() Return One Selection (#4466)
## Summary of the Pull Request
We used to return multiple text ranges to represent one selection. We only support one selection at a time, so we should only return one range.

Additionally, I moved all TriggerSelection() calls to the renderer from Terminal to TermControl for consistency. This ensures we only call it _once_ when we make a change to our selection state.

2dec894515 Fix duplicate copyOnSelect when clicking on an unfocused terminal (#4596)
## Summary of the Pull Request
Currently, clicking on an unfocused terminal with a selection active will trigger `copyOnSelect`. This is because the check for `copyOnSelect` and copying to the clipboard is bound to when the Pointer is released. This works fine for when a user performs a click-drag selection, but it inadvertently also triggers when the user performs a single click on an unfocused terminal. We expect `copyOnSelect` to trigger only on the first time a selection is completed. 

This PR will allow the user to single click on an unfocused terminal that has a selection active without triggering a copyOnSelect. It also ensures that any click-drag selection, whether it's on an unfocused or focused terminal, will trigger copyOnSelect.

8392d6b647 Fix touchpad and touchscreen scrolling (#4554)
Fixed inconsistent scrolling when using both touchscreen and precision
touchpad.

Scrolling jumpiness is caused by rounding errors. Instead of retrieving
the current scrolling value from `GetScrollOffset`, which is already
rounded in `int`, let the scrolling operation to operate on
`_scrollBar`'s `Value` directly (which uses `double`) in
`TermControl.cpp`.

TermControl now also respects WHEEL_DELTA, which it was previously
ignoring, to determine how many scroll wheel detents were used.

Testing scrolling on the following scenario manually:

- nonscrollable terminal (e.g. the window is large enough to contain the
  current buffer).
- scrolling to the topmost and bottom-most.
- scrolling TUI apps such as `nano` and `more` in WSL.
- after clearing the terminal, both in cmd and WSL.

... has the same behavior between using touchscreen or precision trackpad
and regular mouse wheel.

7836da07dd Fix click-drag selection on an unfocused Terminal (#4506)
## Summary of the Pull Request
This PR tries to address some of the weird interactions with pointer pressed events when the Terminal isn't in focus. Here's the four things that have changed as part of this PR;

1. This PR will allow the user to be able to make a selection with a click-drag without having to first perform a single click on a tab/pane to bring it to focus. 
2. Another weird bug that's fixed in this PR is where trying to make a selection on an unfocused tab when it already has a selection active will simply extend the existing selection instead of making a new one.
3. Not related to the issue that his PR closes: a right click will now focus the tab/pane.

I've made sure that we still have the existing functionality where a single click on an unfocused tab/pane does not make a single-cell selection and just focuses the tab/pane.

19ee4277c9 When patching profiles in, copy the user's indentation (#4555)
This will attempt to match the style of the user's JSON.

Caveats:
1. If the user has no profiles, it'll explode. This isn't new.
2. If the user's indentation style if `{profile}, {profile}, {profile}` (that is: no indentation), you'll get this:

```
{profile}, {profile}, {profile},
 {
     new profile content
 }
```

There may be something better we can do by copying their newline (or lack thereof) and using it in our generator or detecting the indentation of their members as well.
That's an exercise for later.

## Detailed Description of the Pull Request / Additional comments
The following data is collected with examples of the types of questions we intend to answer:
1. What is the name of the executable attached to the PTY? (What shells are popular? Should we focus our testing on them? Are there any common ones we are blind to that we should know about?)
- "Microsoft.Windows.Terminal.Connection" {e912fe7b-eeb6-52a5-c628-abe388e5f792}
- "ConPtyConnected" event
- "SessionGuid" value = WT_SESSION 
- "Client" value = Name of EXE
2. Is Acrylic used on a tab? And with what opacity? (Do people really want acrylic? Should it be default? What opacity is most pleasing in our context?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "TabInformation" event
- "EventVer" value is now 1u
- "UseAcrylic" value is now TRUE/FALSE on the setting choice
- "TintOpacity" value is now Float on the setting choice
3. What font are people choosing? (Do people move away from Cascadia Code? Which ones are the most popular for us to validate when updating the renderer?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "TabInformation" event
- "FontFace" value is now string font from settings
4. What keybindings do people choose to customize (Add or Remove)? (Are there extremely common keys that folks bind or unbind that we should have adjusted by default in a fresh install?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "CustomKeybindings" event
- "Keybindings" value is the entire JSON segment that describes the user keybindings from `settings.json`.
5. Do people change their default profile from the PowerShell one we set? If so, to what? (Should we not set PowerShell as the default? Should we adjust the ranking of our dynamic generators to favor the most popular ones to bubble to the top?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "CustomDefaultProfile" event
- "DefaultProfile" value is the GUID of the chosen profile

543f5339d7 Fix the crash when closing Terminal containing multiple tabs. (#4538)
The Terminal would crash when closing it when there are multiple tabs
open. This was due to `TerminalPage` attempting to select a nonexistent
tab.

The block of code that was removed was causing issues when trying to
close all tabs at once. The way we close all our tabs in
`_CloseAllTabs()` was by repeatedly calling
`_RemoveTabViewItemByIndex(0)` until `_tabs.Size() == 0`. The problem
was that `_RemoveTabViewItemByIndex` would eventually call a coroutine
to set the next tab as the `SelectedItem` after removing a tab. The
coroutine would then pass control back to `_CloseAllTabs()` to finish
its loop, and by the time the coroutine resumes control, `_tabs` and
`TabView().TabItems()` would both be empty and it would crash attempting
to focus a tab.

Luckily, the functionality that this block of code provided is really no
longer needed . This code was used to focus on the next tab after
closing a  tab. This might have been written way back when TabView
didn't have this functionality built in. It seems now that after
removing a `TabItem` from the `TabView`, the `SelectedItem` of the
TabView automatically updates, making this block of code unnecessary.

## Validation Steps Performed
Did a lot of multiple tab open and closings and closing the window after
opening a ton of tabs. No crashes seem to occur anymore!
Test cases still pass.

be614c2d48 uia: add support for scrolling the viewport (#4525)
The UIA Provider now scrolls the viewport when necessary. This just fills in the missing virtual function in Terminal to have the same behavior as what it does in ConHost.

* [X] Closes #2361 
* [X] CLA signed.

`ChangeViewport` is now a virtual function at the `ScreenInfoUiaProvider` layer to have access to the TermControl.

In ConHost, we pass this call up to the WindowUiaProvider layer. In Terminal, we don't need to do that because the concept of updating the viewport is handled at the TermControl layer. So we just call that function and _voila_!

a241dbdac0 Move cursor in conpty correctly after a backspace when we've delayed an EOL wrap (#4403)
## Summary of the Pull Request

This is a fix that technically was caused by #357, though we didn't have the Terminal at the time, so I only fixed conhost then. When a client app prints the very last column in the buffer, the cursor is often not _actually_ moved to the next row quite yet. The cursor usually just "floats" on the last character of the row, until something happens. This could be a printable character, which will print it on the next line, or a newline, which will move the cursor to the next line manually, or it could be a backspace, which might take the cursor back a character. 

Conhost and gnome-terminal behave slightly differently here, and wt behaves differently all together. Heck, conhost behaves differently depending on what output mode you're in. 

The scenario in question is typing a full row of text, then hitting backspace to erase the last char of the row.

What we were emitting before in this case was definitely wrong - we'd emit a space at that last row, but then not increment our internal tracker of where the cursor is, so the cursor in conpty and the terminal would be misaligned. The easy fix for this is to make sure to always update the `_lastText` member appropriately. This is the `RightExclusive` change.

The second part of this change is to not be so tricksy immediately following a "delayed eol wrap". When we have just printed the last char like that, always use the VT sequence CUP the next time the cursor moves. Depending on the terminal emulator and it's flags, performing a BS in this state might not bring the cursor to the correct position.

## Detailed Description of the Pull Request / Additional comments

There are two ways scroll can happen:
- the user scrolls using the scroll bar and the `Terminal` is notified
- the `Terminal` changed the viewport and the scroll bar is updated to reflect the change

The code to notify the `Terminal` that the user scrolled is in the event handler for when the scroll bar's value changes. However this poses a problem because it means that when the `Terminal` changes the viewport, the scroll bar is updated so it would then also notify the `Terminal` that the scroll changed. But it already knows because it's coming from itself!

To fix this, the `TermControl` class had a member called `_lastScrollOffset` that would be set when the `Terminal` decides to change the viewport so that the event handler for the scroll bar could check the new scroll value against `_lastScrollOffset` and if it matches, then everything is fine and there is nothing to update.

This is what happens when the `Terminal` changes the viewport:
1. set `_lastScrollOffset`
2. dispatch job on the UI thread: update the scrollbar which is going to call the event handler which is going to check for `_lastScrollOffset` and clear it

There are two bugs introduced by this approach:
1. (I am not sure about this.) The dispatcher appears to store jobs in a LIFO stack so it sometimes reorders the "update the scrollbar" jobs when there are too many. When I run `1..10000` on PowerShell, then I get this from the event handler (format: `_lastScrollOffset newValue`):
    ```
    8988 8988
    8989 8989
    8990 8990
    8992 8991
    8993 8992
    ...
    9001 8997
    9001 8998
    9001 8999
    9001 9000
    9001 9001
    9001 8985
    9001 8968
    9001 8953
    ...
    9001 7242
    9001 7226
    9001 7210
    ```
    This causes the following issues:
    1. `_lastScrollOffset` wouldn't be reset because it wouldn't be equal to the current scroll bar value (see example above) so the next scrolls wouldn't do anything as the event handler would still be waiting for an event with the good scroll bar value which would never happen because it happened earlier
    2. the `TermControl` would notify the `Terminal` about its own scroll
2. If the `Terminal` didn't actually changed its viewport but still called the `TermControl::_TerminalScrollPositionChanged` method, then it would set the `_lastScrollOffset` member as usual but the scroll bar value change event handler would not be called because it is only called when the value actually changes so the `_lastScrollOffset` member wouldn't be cleared and subsequent scroll bar value change events would be ignored because again the event handler would still be waiting for an event with the good scroll bar value which would never happen. This is actually the reason for #1494: when the window is resized, the `Terminal` will call `TermControl::_TerminalScrollPositionChanged` even if the scroll position didn't actually change (444de5b166/src/cascadia/TerminalCore/Terminal.cpp (L183)). Maybe this should also be fixed in another PR?

I replaced `_lastScrollOffset` by a flag `_isTerminalInitiatedScroll`. I set the flag just before and unset it just after the terminal changes the scrollbar on the UI thread to eliminate the race conditions and the bug when the scroll bar's value doesn't actually change.

Other changes:
- I also fixed a potential bug where if the user scrolls just after the terminal updates the viewport, it would en up ignoring the user scroll. To do this, when the user scrolls, I cancel any update with `_willUpdateScrollBarToMatchViewport`.
- I also removed the original `ScrollViewport` method because it was not used anywhere and I think it can potentially create confusion (and therefore bugs) because this method updates the viewport but not the scroll bar unlike `KeyboardScrollViewport` which functions as you would expect. I then renamed `KeyboardScrollViewport` into `ScrollViewport`. So, now, there is only one method to scroll the viewport from the `TermControl`. Please, tell me if this shouldn't be in this PR.
- I also removed `_terminal->UserScrollViewport(viewTop);` in the `KeyboardScrollViewport` method because it will be updated later anyways in the scroll bar's value change event handler because of the `_scrollBar.Value(viewTop);`.

<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed

I tested manually by doing this:
- For bug 1:
    1. Start the terminal
    2. Run the `1..30000` command in PowerShell and wait for it to end (maybe more if you have a fast  computer?)
    3. Hold left click on the scrollbar slider and start moving it
- For bug 2:
    1. Start the terminal
    2. Run the `1..100` command in PowerShell and wait for it to end
    3. Resize the window horizontally
    4. Hold left click on the scrollbar slider and start moving it

Without this patch, the viewport doesn't update.
With the patch, the viewport updates correctly.

This fixes a crash caused by Narrator starting *before* terminal.

Fixes #2907.

For context,

```
// We must initialize the main thread as a single-threaded apartment before
// constructing any Xaml objects. Failing to do so will cause some issues
// in accessibility somewhere down the line when a UIAutomation object will
// be queried on the wrong thread at the wrong time.
// We used to initialize as STA only _after_ initializing the application
// host, which loaded the settings. The settings needed to be loaded in MTA
// because we were using the Windows.Storage APIs. Since we're no longer
// doing that, we can safely init as STA before any WinRT dispatches.

86706d7698 Move tests to invoke te.exe directly instead of using VSTest runner (#4490)
Moves the tests from using the `vstest.console.exe` route to just using `te.exe`.

PROs:
- `te.exe` is significantly faster for running tests because the TAEF/VSTest adapter isn't great.
- Running through `te.exe` is closer to what our developers are doing on their dev boxes
- `te.exe` is how they run in the Windows gates.
- `te.exe` doesn't seem to have the sporadic `0x6` error code thrown during the tests where somehow the console handles get lost
- `te.exe` doesn't seem to repro the other intermittent issues that we have been having that are inscrutable. 
- Fewer processes in the tree (te is running anyway under `vstest.console.exe`, just indirected a lot
- The log outputs scroll live with all our logging messages instead of suppressing everything until there's a failure
- The log output is actually in the order things are happening versus vstest.

CONs:
- No more code coverage.
- No more test records in the ADO build/test panel.
- Tests really won't work inside Visual Studio at all.
- The log files are really big now
- Testing is not a test task anymore, just another script.

Refuting each CON:
- We didn't read the code coverage numbers
- We didn't look at the ADO test panel results or build-over-build velocities
- Tests didn't really work inside Visual Studio anyway unless you did the right incantations under the full moon.
- We could tone down the logging if we wanted at either the te.exe execution time (with a switch) or by declaring properties in the tests/classes/modules that are very verbose to not log unless it fails.
- I don't think anyone cares how they get run as long as they do.

99a28f9e9e Convert Tab to a WinRT type (#4350)
## Summary of the Pull Request
This PR will make the existing `Tab` class into a WinRT type. This will allow any XAML to simply bind to the `ObservableVector` of Tabs. 

This PR will be followed up with a future PR to change our TabView to use the ObservableVector, which will in turn eliminate the need for maintaining two vectors of Tabs. (We currently maintain `_tabs` in `TerminalPage` and we also maintain `TabView().TabViewItems()` at the same time as described here: #2740)

## References
#3922 

## PR Checklist
* [x] CLA signed.
* [x] Tests added/passed

## Detailed Description of the Pull Request / Additional comments
I've currently only exposed a Tab's Title and IconPath to keep things simple. I foresee XAML elements that bind to Tabs to only really need these two properties for displaying.

I've also converted `TerminalPage`'s `std::vector<std::shared_ptr> _tabs` into a `IObservableVector<winrt::TerminalPage::Tab> _tabs` just so that future PRs will have the ground set for binding to this vector of tabs.

## Validation Steps Performed
Played around with Tabs and Panes and all sorts of combinations of keybindings for interacting with tabs and dragging and whatnot, it all seemed fine! Tab Tests also all pass.

0d92f71e45 Add support for VT100 Auto Wrap Mode (DECAWM) (#3943)
## Summary of the Pull Request

This adds support for the [`DECAWM`](https://vt100.net/docs/vt510-rm/DECAWM) private mode escape sequence, which controls whether or not the output wraps to the next line when the cursor reaches the right edge of the screen. Tested manually, with [Vttest](https://invisible-island.net/vttest/), and with some new unit tests.

## Detailed Description of the Pull Request / Additional comments

The idea was to repurpose the existing `ENABLE_WRAP_AT_EOL_OUTPUT` mode, but the problem with that was it didn't work in VT mode - specifically, disabling it didn't prevent the wrapping from happening. This was because in VT mode the `WC_DELAY_EOL_WRAP` behaviour takes affect, and that bypasses the usual codepath where `ENABLE_WRAP_AT_EOL_OUTPUT` is checked,

To fix this, I had to add additional checks in the `WriteCharsLegacy` function (7dbefe06e41f191a0e83cfefe4896b66094c4089) to make sure the `WC_DELAY_EOL_WRAP` mode is only activated when `ENABLE_WRAP_AT_EOL_OUTPUT`  is also set.

Once that was fixed, though, another issue came to light: the `ENABLE_WRAP_AT_EOL_OUTPUT` mode doesn't actually work as documented. According to the docs, "if this mode is disabled, the last character in the row is overwritten with any subsequent characters". What actually happens is the cursor jumps back to the position at the start of the write, which could be anywhere on the line.

This seems completely broken to me, but I've checked in the Windows XP, and it has the same behaviour, so it looks like that's the way it has always been. So I've added a fix for this (9df98497ca38f7d0ea42623b723a8e2ecf9a4ab9), but it is only applied in VT mode.

Once that basic functionality was in place, though, we just needed a private API in the `ConGetSet` interface to toggle the mode, and then that API could be called from the `AdaptDispatch` class when the `DECAWM` escape sequence was received.

One last thing was to reenable the mode in reponse to a `DECSTR` soft reset. Technically the auto wrap mode was disabled by default on many of the DEC terminals, and some documentation suggests that `DECSTR` should reset it to that state, But most modern terminals (including XTerm) expect the wrapping to be enabled by default, and `DECSTR` reenables that state, so that's the behaviour I've copied.

## Validation Steps Performed

I've add a state machine test to confirm the `DECAWM` escape is dispatched correctly, and a screen buffer test to make sure the output is wrapped or clamped as appropriate for the two states.

I've also confirmed that the "wrap around" test is now working correctly in the _Test of screen features_ in Vttest.

## PR Checklist

## Detailed Description of the Pull Request / Additional comments

### Modifications to `InputStateMachineEngine`
I introduced various enum types...
- `CsiIntermediateCodes`: our supported intermediate codes. Currently only `<`
- `CsiEndCodes`: the last code used for SGR Mouse Mode
- `CsiMouseButtonCodes`: which button was pressed. Mutually exclusive. Buttons beyond button 11 are ambiguous.
- `CsiMouseModifierCodes`: bitfield of modifiers active for SGR Mouse Mode.

`CsiIntermediateCodes` is used first in `ActionCsiDispatch` to detect the VT Sequence. This kicks off a chain of function calls...
- `_GetXYPosition()`: figure out where the mouse was clicked
- `_UpdateSGRMouseButtonState`: read in what we found and update our internal state
- `_WriteMouseEvent()`: generate an INPUT_RECORD and send it off

### Modifications to Testing Suite
read below.
Also, made the test state a globally accessible/modifiable variable.

## Validation Steps Performed
Added tests that cover...
- button clicks
- button clicks with modifiers
- mouse movement
- mouse movement and entering/exiting a state where multiple buttons were pressed

#3279 - Make Search a shared component
#4018 - UiaTextRange Refactor

I removed it from the two different kinds of UiaTextRange and put it in the base class.

I needed a very minor change to ensure we convert from an inclusive end (from Search) to an exclusive end (in UTR).

Worked with `FindText` was globally messed with in windows.h. So we had to do a few weird things there (thanks Michael).

No need for additional tests because it _literally_ just sets up a Searcher and calls it.

29df540174 Refactor UiaTextRange For Improved Navigation and Reliability (#4018)
## Summary of the Pull Request
This pull request is intended to achieve the following goals...
1) reduce duplicate code
2) remove static functions
3) improve readability
4) improve reliability
5) improve code-coverage for testing
6) establish functioning text buffer navigation in Narrator and NVDA

This also required a change to the wrapper class `XamlUiaTextRange` that has been causing issues with Narrator and NVDA.

See below for additional context.

## References
#3976 - I believe this might have been a result of improperly handling degenerate ranges. Fixed here.
#3895 - reduced the duplicate code. No need to separate into different files
#2160 - same as #3976 above
#1993 - I think just about everything is no longer static

## PR Checklist
* [x] Closes #3895, Closes #1993, Closes #3976, Closes #2160 
* [x] CLA signed
* [x] Tests added/passed

## Detailed Description of the Pull Request / Additional comments

### UiaTextRange
- converted endpoints into the COORD system in the TextBuffer coordinate space
- `start` is inclusive, `end` is exclusive. A degenerate range is when start == end.
- all functions are no longer static
- `MoveByUnit()` functions now rely on `MoveEndpointByUnit()` functions
- removed unnecessary typedefs like `Endpoint`, `ScreenInfoRow`, etc..
- relied more heavily on existing functionality from `TextBuffer` and `Viewport`

### XamlUiaTextRange
- `GetAttributeValue()` must return a special HRESULT that signifies that the requested attribute is not supported. This was the cause of a number of inconsistencies between Narrator and NVDA.
- `FindText()` should return `nullptr` if nothing was found. #4373 properly fixes this functionality now that Search is a shared module

### TextBuffer
- Word navigation functionality is entirely in `TextBuffer` for proper abstraction
- a total of 6 functions are now dedicated to word navigation to get a good understanding of the differences between a "word" in Accessibility and a "word" in selection

As an example, consider a buffer with this text in it:
"  word   other  "
In selection, a "word" is defined as the range between two delimiters, so the words in the example include ["  ", "word", "   ", "other", "  "].
In accessibility , a "word" includes the delimiters after a range of readable characters, so the words in the example include ["word   ", "other  "].

Additionally, accessibility word navigation must be able to detect if it is on the first or last word. This resulted in a slight variant of word navigation functions that return a boolean instead of a COORD.

Ideally, these functions can be consolidated, but that is too risky for a PR of this size as it can have an effect on selection.

### Viewport
- the concept of `EndExclusive` is added. This is used by UiaTextRange's `end` anchor as it is exclusive. To signify that the last character in the buffer is included in this buffer, `end` must be one past the end of the buffer. This is `EndExclusive`
- Since many functions check if the given `COORD` is in bounds, a flag must be set to allow `EndExclusive` as a valid `COORD` that is in bounds.

### Testing
- word navigation testing relies more heavily on TextBuffer tests
- additional testing was created for non-movement focused functions of UiaTextRange
- The results have been compared to Microsoft Word and some have been verified by UiAutomation/Narrator contacts as expected results.

7e2f51face A pair of fixes related to cursor movement in conpty (#4372)
## Summary of the Pull Request

This is a pair of related fixes to conpty. For both of these bugs, the root cause was that the cursor was getting set to Off in conpty. Without the `CursorBlinkerTimer`, the cursor would remain off, and frames that only had cursor movements would not update the cursor position in the terminal.

## References

## PR Checklist
* [x] Closes #4102 
* [x] Closes #2642
* [x] I work here
* [ ] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments

Recall that there's a bunch of cursor state that's hard to parse without looking up:
* `Visibility` This controls whether the cursor is visible _at all_, regardless if it's been blinked on or off
* `Blinking` controls whether the blinker timer should do something, or leave the cursor alone.
* `IsOn`: When the cursor is blinking, this alternates between true and false. 

The trick here is that we only `TriggerCursorMoved` when the cursor is `On`, and there are some scenarios where the cursor is manually set to off. 

Fundamentally, these two bugs are similar cases, but they are triggered by different things:
* #2642 was caused by `DoSrvPrivateAllowCursorBlinking(false)` (`^[[?12l`) also manually turning the cursor off.
* #4102 was caused by the client calling `SetConsoleScreenBuffer` to change the active buffer. `win-curses` actually uses that API instead of the alt buffer.

c69757ec9e Remove unneeded VT-specific control character handling (#4289)
## Summary of the Pull Request

This PR removes all of the VT-specific functionality from the `WriteCharsLegacy` function that dealt with control characters, since those controls are now handled in the state machine when in VT mode. It also removes most of the control character handling from the `Terminal::_WriteBuffer` method for the same reason.

## References

This is a followup to PR #4171

* [x] CLA signed. If not, go over [here](https://cla.opensource.microsoft.com/microsoft/Terminal) and sign the CLA

## Detailed Description of the Pull Request / Additional comments

There are four changes to the `WriteCharsLegacy` implementation:

1. The `TAB` character had special case handling in VT mode which is now no longer required. This fixes a bug in the Python REPL editor (when run from a cmd shell in Windows Terminal), which would prevent you tabbing past the end of the line. It also fixes #3971.

2. Following on from point 1, the `WC_NONDESTRUCTIVE_TAB` flag could also now be removed. It only ever applied in VT mode, in which case the `TAB` character isn't handled in `WriteCharsLegacy`, so there isn't a need for a non-destructive version.

3. There used to be special case handling for a `BS` character at the beginning of the line when in VT mode, and that is also no longer required. This fixes an edge-case bug which would prevent a glyph being output for code point 8 when `ENABLE_PROCESSED_OUTPUT` was disabled. 

4. There was quite a lot of special case handling for control characters in the "end-of-line wrap" implementation, which is no longer required. This fixes a bug which would prevent "low ASCII" characters from wrapping when output at the end of a line.

Then in the `Terminal::_WriteBuffer` implementation, I've simply removed all control character handling, except for `LF`. The Terminal is always in VT mode, so the control characters are always handled by the state machine. The exception for the `LF` character is simply because it doesn't have a proper implementation yet, so it still passes the character through to `_WriteBuffer`. That will get cleaned up eventually, but I thought that could wait for a later PR.

Finally, with the removal of the VT mode handling in `WriteCharsLegacy`, there was no longer a need for the `SCREEN_INFORMATION::InVTMode` method to be publicly accessible. That has now been made private.

## Validation Steps Performed

I've only tested manually, making sure the conhost and Windows Terminal still basically work, and confirming that the above-mentioned bugs are fixed by these changes.

685720a767 Add just the test infrastructure bits from #4354 (#4382)
## Summary of the Pull Request

#4354 is a pretty complicated PR. It's got a bunch of conpty changes, but what it also has was some critical improvements to the roundtrip test suite. I'm working on some other bugfixes in the same area currently, and need these tests enhancements in those branches _now_. The rest of #4354 is complex enough that I don't trust it will get merged soon (if ever). However, these fixes _should_ be in regardless.

## PR Checklist
* [x] Taken directly from #4354
* [x] I work here
* [x] Tests added/passed
* [n/a] Requires documentation to be updated

## Detailed Description of the Pull Request / Additional comments

This is four main changes:
* Enable conpty to be fully enabled in unittests. Just setting up a VT renderer isn't enough to trick the host into being in conpty mode - it also needs to have some other flags set.
* Some minor changes to `CommonState` to better configure the common test state for conpty
* Move some of the verify helpers from `ConptyRoundtripTests` into their own helper class, to be shared in multiple tests
* Add a `TerminalBufferTests` class, for testing the Terminal buffer directly (without conpty).

This change is really easier than

🛑 **STOP** 🛑 - have you read #3495 yet? If you haven't, go do that now.

This PR adds support for three initial sub-commands to the `wt.exe` application:
* `new-tab`: Used to create a new tab.
* `split-pane`: Used to create a new split.
* `focus-tab`: Moves focus to another tab.

These commands are largely POC to prove that the commandlines work. They're not totally finished, but they work well enough. Follow up work items will be filed to track adding support for additional parameters and subcommands

Important scenarios added:
* `wt -d .`: Open a new wt instance in the current working directory #878
* `wt -p <profile name>`: Create a wt instance running the given profile, to unblock  #576, #1357, #2339
* `wt ; new-tab ; split-pane -V`: Launch the terminal with multiple tabs, splits, to unblock #756

e675de3a88 Add support for the DECSCNM screen mode (#3817)
## Summary of the Pull Request

This adds support for the [`DECSCNM`](https://vt100.net/docs/vt510-rm/DECSCNM.html) private mode escape sequence, which toggles the display between normal and reverse screen modes. When reversed, the background and foreground colors are switched. Tested manually, with [Vttest](https://invisible-island.net/vttest/), and with some new unit tests.

## References

This also fixes issue #72 for the most part, although if you toggle the mode too fast, there is no discernible flash.

* [ ] I've discussed this with core contributors already. If not checked, I'm ready to accept this work might be rejected in favor of a different grand plan. Issue number where discussion took place: #xxx

## Detailed Description of the Pull Request / Additional comments

I've implemented this as a new flag in the `Settings` class, along with updates to the `LookupForegroundColor` and `LookupBackgroundColor` methods, to switch the returned foreground and background colors when that flag is set. 

It also required a new private API in the `ConGetSet` interface to toggle the setting. And that API is then called from the `AdaptDispatch` class when the screen mode escape sequence is received.

The last thing needed was to add a step to the `HardReset` method, to reset the mode back to normal, which is one of the `RIS` requirements.

Note that this does currently work in the Windows Terminal, but once #2661 is implemented that may no longer be the case. It might become necessary to let the mode change sequences pass through conpty, and handle the color reversing on the client side.
 
## Validation Steps Performed

I've added a state machine test to make sure the escape sequence is dispatched correctly, and a screen buffer test to confirm that the mode change does alter the interpretation of colors as expected.

I've also confirmed that the various "light background" tests in Vttest now display correctly, and that the `tput flash` command (in a bash shell) does actually cause the screen to flash.

cbb87b98b7 Add support for the HPR and VPR escape sequences (#4297)
## Summary of the Pull Request

This PR adds support for the `HPR` and `VPR`  escape sequences from the VT510 terminal. `HPR` moves the cursor position forward by a given number of columns, and `VPR` moves the cursor position downward by a given number of rows. They're similar in function to the `CUF` and `CUD` escape sequences, except that they're not constrained by the scrolling margins.

## References

#3628 provided the new `_CursorMovePosition` method that made these operations possible

## Detailed Description of the Pull Request / Additional comments

Most of the implementation is in the new `_CursorMovePosition` method that was created in PR #3628, so all we're really doing here is hooking up the escape sequences to call that method with the appropriate parameters.

## Validation Steps Performed

I've extended the existing state machine tests for CSI cursor movement to confirm that the `HPR` and `VPR` sequences are dispatched correctly, and also added screen buffer tests to make sure the movement is clamped by the screen boundaries and not the scrolling margins (we don't yet support horizontal margins, but the test is at least in place for when we do eventually add that support).

I've also checked the `HPR` and `VPR` tests in Vttest (under _Test non-VT100 / ISO-6429 cursor-movement_) and confirmed that they are now working as expected.

## Detailed Description of the Pull Request / Additional comments

Currently, it seems like CustomTextLayout::_CorrectGlyphRun generally assumes that glyphs and characters have a 1:1 mapping relationship - which holds true for most trivial scenarios with basic western scripts, and also many, but unfortunately not all, monospace "programming" fonts with programming ligatures.

This change makes terminal correctly processes glyphs that represents multiple characters, by properly accumulating the column counts of all these characters together (which I believe is more close to what this code originally intended to do).

There are still many issues existing in both CustomTextLayout as well as the TextBuffer, and the correct solution to them will likely demand large-scale changes, at least at the scale of #3578. I wish small changes like this can serve as a stop gap solution while we take our time to work on the long-term right thing.

* Then I got crazy and thought _"what if I could take that output and dump it straight into the `Terminal`"_? Hence, the `ConptyRoundtripTests` were born, into the TerminalCore unit tests.

## Detailed Description of the Pull Request / Additional comments

From the comment in `ConptyRoundtripTests`:
> This test class creates an in-proc conpty host as well as a Terminal, to
> validate that strings written to the conpty create the same resopnse on the
> terminal end. Tests can be written that validate both the contents of the
> host buffer as well as the terminal buffer. Everytime that
> `renderer.PaintFrame()` is called, the tests will validate the expected
> output, and then flush the output of the VtEngine straight to th

Also, some other bits had to be updated:
* The renderer needed to be able to survive without a thread, so I hadded a simple check that it actually had a thread before calling `pThread->NotifyPaint`
* Bits in `CommonState` used `NTSTATUS_FROM_HRESULT` which did _not_ work outside the host project. Since the `NTSTATUS` didn't seem that important, I replaced that with a `HRESULT`
* `CommonState` likes to initialize the console to some _weird_ defaults. I added an optional param to let us just use the defaults.

77dd51af39 Fix crash related to unparseable/invalid media resource paths (#4194)
WT crashes when an unparseable/invalid `backgroundImage` or `icon`
resource path is provided in `profiles.json`. This PR averts the crash
by the validating and correcting resource paths as a part of the
`_ValidateSettings()` function in `CascadiaSettings`.
`_ValidateSettings()` is run on start up and any time `profiles.json` is
changed, so a user can not change a file path and avoid the validation
step. 

When a bad `backgroundImage` or `icon` resource path is detected, a
warning screen will be presented.

References #4002, which identified a consistent repro for the crash.

To validate the resource, a `Windows::Foundation::Uri` object is
constructed with the path. The ctor will throw if the resource path is
invalid. Whether or not this validation method is robust enough is a
subject worth review. The correction method for when a bad resource path
is detected is to reset the `std::optional<winrt::hstring>` holding the
file path. 

The text in the warning display was cribbed from the text used when an
invalid `colorScheme` is used. Whether or not the case of a bad
background image file path warrants a warning display is a subject worth
review.

Ensured the repro steps in #4002 did not trigger a crash. Additionally,
some potential backdoor paths to a crash were tested: 

- Deleting the file of a validated background image file path
- Changing the actual file name of a validated background image file
  path
- Replacing the file of a validated background image file path with a
  non-image file (of the same name)
- Using a non-image file as a background image

In all the above cases WT does not crash, and instead defaults to the
background color specified in the profile's `colorScheme`. This PR does
not implement this recovery behavior (existing error catching code
does).

Closes #2329

0586955c88 Dispatch more C0 control characters from the VT state machine (#4171)
This commit moves the handling of the `BEL`, `BS`, `TAB`, and `CR`
controls characters into the state machine (when in VT mode), instead of
forwarding them on to the default string writer, which would otherwise
have to parse them out all over again.

This doesn't cover all the control characters, but `ESC`, `SUB`, and
`CAN` are already an integral part of the `StateMachine` itself; `NUL`
is filtered out by the `OutputStateMachineEngine`; and `LF`, `FF`, and
`VT`  are due to be implemented as part of PR #3271.

Once all of these controls are handled at the state machine level, we
can strip out all the VT-specific code from the `WriteCharsLegacy`
function, which should simplify it considerably. This would also let us
simplify the `Terminal::_WriteBuffer` implementation, and the planned
replacement stream writer for issue #780.

On the conhost side, the implementation is handled as follows:

* The `BS` control is dispatched to the existing `CursorBackward`
  method, with a distance of 1.
* The `TAB` control is dispatched to the existing `ForwardTab` method,
  with a tab count of 1.
* The `CR` control required a new dispatch method, but the
  implementation was a simple call to the new `_CursorMovePosition` method
  from PR #3628.
* The `BEL` control also required a new dispatch method, as well as an
  additional private API in the `ConGetSet` interface. But that's mostly
  boilerplate code - ultimately it just calls the `SendNotifyBeep` method.

On the Windows Terminal side, not all dispatch methods are implemented.

* There is an existing `CursorBackward` implementation, so `BS` works
  OK.
* There isn't a `ForwardTab` implementation, but `TAB` isn't currently
  required by the conpty protocol.
* I had to implement the `CarriageReturn` dispatch method, but that was
  a simple call to `Terminal::SetCursorPosition`.
* The `WarningBell` method I've left unimplemented, because that
  functionality wasn't previously supported anyway, and there's an
  existing issue for that (#4046).

## Validation Steps Performed

I've added a state machine test to confirm that the updated control
characters are now forwarded to the appropriate dispatch handlers. But
since the actual implementation is mostly relying on existing
functionality, I'm assuming that code is already adequately tested
elsewhere. That said, I have also run various manual tests of my own,
and confirmed that everything still worked as well as before.

2fec1787a0 Improve the VT cursor movement implementation (#3628)
## Summary of the Pull Request

Originally there were 3 different methods for implementing VT cursor movement, and between them they still couldn't handle some of the operations correctly. This PR unifies those operations into a single method that can handle every type of cursor movement, and which fixes some of the issues with the existing implementations. In particular it fixes the `CNL` and `CPL` operations, so they're now correctly constrained by the `DECSTBM` margins.

## References

If this PR is accepted, the method added here should make it trivial to implement the `VPR` and `HPR` commands in issue #3428.

## Detailed Description of the Pull Request / Additional comments

The new [`AdaptDispatch::_CursorMovePosition`](d6c4f35cf6/src/terminal/adapter/adaptDispatch.cpp (L169)) method is based on the proposal I made in issue #3428 for the `VPR` and `HPR` comands. It takes three arguments: a row offset (which can be absolute or relative), a column offset (ditto), and a flag specifying whether the position should be constrained by the `DECSTBM` margins.

To make the code more readable, I've implemented the offsets using [a `struct` with some `constexpr` helper functions for the construction](d6c4f35cf6/src/terminal/adapter/adaptDispatch.hpp (L116-L125)). This lets you specify the parameters with expressions like `Offset::Absolute(col)` or `Offset::Forward(distance)` which I think makes the calling code a little easier to understand.

While implementing this new method, I noticed a couple of issues in the existing movement implementations which I thought would be good to fix at the same time.

1. When cursor movement is constrained horizontally, it should be constrained by the buffer width, and not the horizontal viewport boundaries. This is an issue I've previously corrected in other parts of the codebase, and I think the cursor movement was one of the last areas where it was still a problem.

2. A number of the commands had range and overflow checks for their parameters that were either unnecessary (testing for a condition that could never occur) or incorrect (if an operation overflows, the correct behavior is to clamp it, and not just fail). The new implementation handles legitimate overflows correctly, but doesn't check for impossible ranges.

Because of the change of behavior in point 1, I also had to update the implementations of [the `DECSC` and `CPR` commands](9cf7a9b577) to account for the column offset now being relative to the buffer and not the viewport, otherwise those operations would no longer work correctly.

## Validation Steps Performed

Because of the two changes in behavior mentioned above, there were a number of adapter tests that stopped working and needed to be updated. First off there were those that expected the column offset to be relative to the left viewport position and constrained by the viewport width. These now had to be updated to [use the full buffer width](49887a3589) as the allowed horizontal extent.

Then there were all the overflow and out-of-range tests that were testing conditions that could never occur in practice, or where the expected behavior that was tested was actually incorrect. I did spend some time trying to see if there was value in updating these tests somehow, but in the end I decided it was best to just [drop them](6e80d0de19) altogether.

For the `CNL` and `CPL` operations, there didn't appear to be any existing tests, so I added some [new screen buffer tests](d6c4f35cf6) to check that those operations now work correctly, both with and without margins.

## Detailed Description of the Pull Request / Additional comments

I've added a `LineFeed` method to the `ITermDispatch` interface, with an enum parameter specifying the required line feed type (i.e. with carriage return, without carriage return, or dependent on the [`LNM` mode](https://vt100.net/docs/vt510-rm/LNM.html)). The output state machine can then call that method to handle the various line feed control characters (parsed in the `ActionExecute` method), as well the `NEL` and `IND` escape sequences (parsed in the `ActionEscDispatch` method).

The `AdaptDispatch` implementation of `LineFeed` then forwards the call to a new `PrivateLineFeed` method in the `ConGetSet` interface, which simply takes a bool parameter specifying whether a carriage return is required or not. In the case of mode-dependent line feeds, the `AdaptDispatch` implementation determines whether the return is necessary or not, based on the existing _AutoReturnOnNewLine_ setting (which I'm obtaining via another new `PrivateGetLineFeedMode` method).

Ultimately we'll want to support changing the mode via the [`LNM` escape sequence](https://vt100.net/docs/vt510-rm/LNM.html), but there's no urgent need for that now. And using the existing _AutoReturnOnNewLine_ setting as a substitute for the mode gives us backwards compatible behaviour, since that will be true for the Windows shells (which expect a linefeed to also generate a carriage return), and false in a WSL bash shell (which won't want the carriage return by default).

As for the actual `PrivateLineFeed` implementation, that is just a simplified version of how the line feed would previously have been executed in the `WriteCharsLegacy` function. This includes setting the cursor to "On" (with `Cursor::SetIsOn`), potentially clearing the wrap property of the line being left (with `CharRow::SetWrapForced` false), and then setting the new position using `AdjustCursorPosition` with the _fKeepCursorVisible_ parameter set to false.

I'm unsure whether the `SetIsOn` call is really necessary, and I think the way the forced wrap is handled needs a rethink in general, but for now this should at least be compatible with the existing behaviour.

Finally, in order to make this all work in the _Windows Terminal_ app, I also had to add a basic implementation of the `ITermDispatch::LineFeed` method in the `TerminalDispatch` class. There is currently no need to support mode-specific line feeds here, so this simply forwards a `\n` or `\r\n` to the `Execute` method, which is ultimately handled by the `Terminal::_WriteBuffer` implementation.

## Validation Steps Performed

I've added output engine tests which confirm that the various control characters and escape sequences trigger the dispatch method correctly. Then I've added adapter tests which confirm the various dispatch options trigger the `PrivateLineFeed` API correctly. And finally I added some screen buffer tests that check the actual results of the `NEL` and `IND` sequences, which covers both forms of the `PrivateLineFeed` API (i.e. with and without a carriage return).

I've also run the _Test of cursor movements_ in the [Vttest](https://invisible-island.net/vttest/) utility, and confirmed that screens 1, 2, and 5 are now working correctly. The first two depend on `NEL` and `IND` being supported, and screen 5 requires the `VT` control character.

## Detailed Description of the Pull Request / Additional comments

In `SCREEN_INFORMATION::ResizeScreenBuffer`, the screenbuffer needs to create a new buffer, and copy the contents of the old buffer into the new one. I'm moving that "copy contents from the old buffer to the new one" step to it's own helper, as a static function on `TextBuffer`. That way, when the time comes to implement this for the Terminal, the hard part of the code will already be there.

## Validation Steps Performed

Ideally, all the tests will still pass.

1ca29128d4 Fix redundant CR in formatted text copy (#4190)
## Summary of the Pull Request

When `GenHTML` or `GenRTF` encountered an empty line, they assumed that `CR` is the last character of the row and wrote it, even though in general `CR` and `LF` just break the line and instead of them either `<BR>` in HTML or `\line` in RTF is written. Don't know how I missed that in #2038.

Another question is whether the `TextAndColor` structure which these methods receive and which is generated by `TextBuffer::GetTextForClipboard` should really contain `\r\n` at the end of each row. I think it'd be cleaner if it didn't esp. that afaik these last 2 characters don't have associated valid color information.

bf86a961f0 Reverse the behavior of the IS_GLYPH_CHAR macro so its function now matches its name. (#4209)
## Summary of the Pull Request

This PR reverses the behaviour of the `IS_GLYPH_CHAR` macro, so it now actually returns true if the given char is a glyph, and false if it isn't. Previously it returned the opposite of that, which meant it had to be called as `!IS_GLYPH_CHAR` to get the correct result.

## Detailed Description of the Pull Request / Additional comments

The original implementation returned true if the given character was a C0 control, or a DEL:

    #define IS_GLYPH_CHAR(wch) (((wch) < L' ') || ((wch) == 0x007F))

It's now the exact opposite, so returns true for characters that are _not_ C0 controls, and are not the DEL character either: 

    #define IS_GLYPH_CHAR(wch) (((wch) >= L' ') && ((wch) != 0x007F))

The macro was only used in one place, where is was being called as `!IS_GLYPH_CHAR` when the intent was actually to test whether the char _was_ a glyph. That code could now be updated to remove the `!`, so it makes more sense.

## Validation Steps Performed

I've just tested manually and confirmed that basic output of text and control chars still worked as expected in a conhost shell.

4129ceb904 stab in the dark to fix x86 tests. (#4202)
## Summary of the Pull Request
Perform checking on `std::basic_string_view<T>.substr()` calls to
prevent running out of bounds and sporadic Privileged Instruction throws
during x86 tests.

## PR Checklist
* [x] Closes the x86 tests failing all over the place since #4125 for no
  apparent reason
* [x] I work here
* [x] Tests pass 

## Detailed Description of the Pull Request / Additional comments
It appears that not all `std::basic_string_view<T>.substr()` calls are
created equally. I rooted around for other versions of the code in our
source tree and found several versions that were less careful about
checking the start position and the size than the one that appears when
building locally on dev machines. 

My theory is that one of these older versions is deployed somewhere in
the CI. Instead of clamping down the size parameter appropriately or
throwing correctly when the position is out of bounds, I believe that
it's just creating a substring with a bad range over an
invalid/uninitialized memory region. Then when the test operates on
that, sometimes it turns out to trigger the privileged instruction
NTSTATUS error we are seeing in CI.

## Test Procedure
1. Fixed the thing
2. Ran the CI and it worked
3. Reverted everything and turned off all of the CI build except just
   the parser tests (and supporting libraries)
4. Ran CI and it failed
5. Put the fix back on top (cherry-pick)
6. It worked.
7. Ran it again.
8. It worked.
9. Turn all the rest of the CI build back on

## Summary of the Pull Request

This PR introduces a new project, `TestHostApp`. This project is largely taken from the TAEF samples, and allows us to easily construct a helper executable and `resources.pri` for running TerminalApp unittests.

* [x] is Tests
* [n/a] Requires documentation to be updated
* [x] **Waiting for an updated version of TAEF to be available**

## Detailed Description of the Pull Request / Additional comments

Unittesting for the TerminalApp project has been a horrifying process to try getting everything pieced together just right. Dependencies need to get added to manifests, binplaced correctly, and XAML resources need to get compiled together as well. In addition, using a MUX `Application` (as opposed to the Windows.UI.Xaml `Application`) has led to additional problems. 

This was always a horrifying house of cards for us. Turns out, the reason this was so horrible is that the test infrastructure for doing what we're doing _literally didn't exist_ when I started doing all that work last year.

So, with help from the TAEF team, I was able to get rid of our entire house of cards, and use a much simpler project to build and run the tests.

Unfortunately, the latest TAEF release has a minor bug in it's build rules, and only publishes the x86 version of a dll we need from them. But, the rest of this PR works for x86, and I'll bump this when that updated version is available. We should be able to review this even in the state it's in.

3ac32af848 Converts Dispatcher().RunAsync to WinRT Coroutines (#4051)
<!-- Enter a brief description/summary of your PR here. What does it fix/what does it change/how was it tested (even manually, if necessary)? -->
## Summary of the Pull Request
This PR turns all* instances of `Dispatcher().RunAsync` to WinRT coroutines 👌. 
This was good coding fodder to fill my plane ride ✈️. Enjoy your holidays everyone!

*With the exception of three functions whose signatures cannot be changed due to inheritance and function overriding in `TermControlAutomationPeer` [`L44`](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalControl/TermControlAutomationPeer.cpp#L44), [`L58`](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalControl/TermControlAutomationPeer.cpp#L58),  [`L72`](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalControl/TermControlAutomationPeer.cpp#L72).

## Detailed Description of the Pull Request / Additional comments
My thought pattern here was to minimally disturb the existing code where possible. So where I could, I converted existing functions into coroutine using functions (like in the [core example](https://github.com/microsoft/terminal/issues/3919#issue-536598706)). For ~the most part~ all instances, I used the format where [`this` is accessed safely within a locked scope](https://github.com/microsoft/terminal/issues/3919#issuecomment-564730620). Some function signatures were changed to take objects by value instead of reference, so the coroutines don't crash when the objects are accessed past their original lifetime. The [copy](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1132) and [paste](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1170) event handler entry points were originally set to a high priority; however, the WinRT coroutines don't appear to support a priority scheme so this priority setting was not preserved in the translation.

<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
Compiles and runs, and for every event with a clear trigger repro, I triggered it to ensure crashes weren't introduced.

[Git2Git] Merged PR 4177564: Use CopyTo when returning WindowUiaProvider child to ensure proper ref count

`WindowUiaProvider` was giving up copies of the pointer to its child `ScreenInfoUiaProvider` without `AddRef`ing them. This means that the receiver of those pointers was `Release`ing them at some later time, causing the internal count to decrement, sometimes all the way to zero.

The crash occurs when a `Signal` comes in and `WindowUiaProvider` attempts to resolve it through `ScreenInfoUiaProvider` but it is already gone because it has been `Release`d all the way to 0 (despite the pointer still being held by `WindowUiaProvider`). The crash then manifests in a bunch of different stacks depending on what part of `ScreenInfoUiaProvider` gets the most unlucky at executing through the now uninitialized memory.

I searched the codebase for more instances of `*ppProvider` and assignments of bare pointers. @<Carlos Zamora> appears to have already got nearly all of them in a previous refactoring operation to prepare our classes to use `WRL` more broadly. These were the only two I could find remaining.

97232b8c49 Merged PR 3344119: Change ParseNext function in UTF16 parser to never yield invalid data… (GH1129)
Change ParseNext function in UTF16 parser to never yield invalid data… (GH1129)

The solution here isn't perfect and isn't going to solve all of our problems. I was basically trying to stop the crash while not getting in the way of the other things coming down the pipe for the input channels.

I considered the following:
1. Remove the fail fast assertion from the buffer
  - I didn't want to do this because it really is invalid to get all the way to placing the text down into the buffer and then request a string of 0 length get inserted. I feel the fail fast is a good indication that something is terribly wrong elsewhere that should be corrected.
2. Update the UTF16 parser in order to stop returning empty strings
  - This is what I ultimately did. If it would ever return just a lead, it returns �. If it would ever return just a trail, it returns �. Otherwise it will return them as a pair if they're both there, or it will return a single valid codepoint. I am now assuming that if the parse function is being called in an Output Iterator and doesn't contain a string with all pieces of the data that are needed, that someone at a higher level messed up the data, it is in valid, and it should be repaired into replacements.
  - This then will move the philosophy up out of the buffer layer to make folks inserting into the buffer identify half a sequence (if they're sitting on a stream where this circumstance could happen... one `wchar_t` at a time) and hold onto it until the next bit arrives. This is because there can be many different routes into the buffer from many different streams/channels. So buffering it low, right near the insertion point, is bad as it might pair loose `wchar_t` across stream entrypoints.
3. Update the iterator, on creating views, to disallow/transform empty strings.
  - I considered this solution as well, but it would have required, under some circumstances, a second parsing of the string to identify lead/trail status from outside the `Utf16Parser` class to realize when to use the � character. So I avoided the double-parse.
4. Change the cooked read classes to identify that they pulled the lead `wchar_t` from a sequence then try to pull another one.
   - I was going to attempt this, but @adiviness said that he tried it and it made all sorts of other weirdness happen with the edit line.
   - Additionally, @adiviness has an outstanding series of effort to make cooked read significantly less horrible and disgusting. I didn't want to get in the way here.
5. Change the `GetChar` method off of the input buffer queue to return a `char32_t`, a `wstring_view`, transform a standalone lead/trail, etc.
    - The `GetChar` method is used by several different accessors and API calls to retrieve information off of the input queue, transforming the Key events into straight up characters. To change this at that level would change them all.  Long-term, it is probably warranted to do so as all of those consumers likely need to become aware of hand ...

8b092f003d Merged PR 3344047: Flush input queue before running test. #1137 (#1139)
Flush input queue before running test. #1137 (#1139)

Flushes the input queue on RawReadUnpacksCoalescedInputRecords test to ensure that other tests cannot cause failure by leaving extraneous input records behind after they run.

This only failed in the core operating system gate tests. This is because those tests run a subset of the complete test suite (subtracting the ones that do not make sense in a core environment). Apparently one of the tests that was skipped that normally runs prior to the UnpacksCoalesced test ensured that the input queue was clean enough for this test to succeed. But in the core environment, the test that ran prior left stuff behind.

To resolve this, I'm making the Coalesced test more resilient by cleaning out the queue prior to performing its operations.

(Also, bonus, I'm fixing the typo in the name Coalesced.)

This is less complicated/expensive than tracking down the tests that are leaving garbage behind, should prevent issues in the future related to ordering (since the tests run alphabetically, by default), and isn't as expensive as running the test in isolation (with its own conhost stood up for just the one test.)

Validated by running te.exe Microsoft.Console.Host.FeatureTests.dll /name:*InputTests* against a core operating system variant. Prior to change, this test failed. After the change, this test succeeded.

This will be automatically double-checked by the gates run after check-in.

If items relate to a ...
* binary file (or some other file you wouldn't want to check at all).
Please add a file path to the `excludes.txt` file matching the containing file.
File paths are Perl 5 Regular Expressions - you can [test](
https://www.regexplanet.com/advanced/perl/) yours before committing to verify it will match your files.
`^` refers to the file's path from the root of the repository, so `^README\.md$` would exclude [README.md](
../tree/HEAD/README.md) (on whichever branch you're using).
* well-formed pattern.
If you can write a [pattern](https://github.com/check-spelling/check-spelling/wiki/Configuration-Examples:-patterns) that would match it,
try adding it to the `patterns.txt` file.
Patterns are Perl 5 Regular Expressions - you can [test](
https://www.regexplanet.com/advanced/perl/) yours before committing to verify it will match your lines.
Note that patterns can't match multiline strings.

# Allow files are lists of words to accept unconditionally
While check spelling will complain about an expected word
which is no longer present, you can include things here even if
they are not otherwise present in the repository.
E.g., you could include a list of system APIs here, or potential
contributors (so that if a future commit includes their name,
it'll be accepted).
## Files
| File | Description |
| ---- | ----------- |
| [Allow](allow.txt) | Supplements to the dictionary |
| [Chinese](chinese.txt) | Chinese words |
| [Japanese](japanese.txt) | Japanese words |
| [Microsoft](microsoft.txt) | Microsoft brand items |
| [Fonts](fonts.txt) | Font names |
| [Names](names.txt) | Names of people |
| [Colors](colors.txt) | Names of color |

These terms are things which temporarily exist in the project, but which
aren't necessarily words.
If something is a word that could come and go, it probably belongs in a

Each line is a Perl 5 regular expression.
Nothing is guaranteed about the order in which they're merged.

Note: order of the contents of these files can matter.
Lines from an individual file are handled in file order.
Files are selected in alphabetical order.
* [n](0_n.txt), [r](0_r.txt), and [t](0_t.txt) are specifically to work around
a quirk in the spell checker:
it often sees C strings of the form "Hello\nwerld". And would prefer to
spot the typo of `werld`.

# Comment management is handled through a secondary job, for details see:
# https://github.com/check-spelling/check-spelling/wiki/Feature%3A-Restricted-Permissions
#
# `jobs.comment-push` runs when a push is made to a repository and the `jobs.spelling` job needs to make a comment
# (in odd cases, it might actually run just to collapse a commment, but that's fairly rare)
# it needs `contents: write` in order to add a comment.
#
# `jobs.comment-pr` runs when a pull_request is made to a repository and the `jobs.spelling` job needs to make a comment
# or collapse a comment (in the case where it had previously made a comment and now no longer needs to show a comment)
# it needs `pull-requests: write` in order to manipulate those comments.
# Updating pull request branches is managed via comment handling.
# For details, see: https://github.com/check-spelling/check-spelling/wiki/Feature:-Update-expect-list
#
# These elements work together to make it happen:
#
# `on.issue_comment`
# This event listens to comments by users asking to update the metadata.
#
# `jobs.update`
# This job runs in response to an issue_comment and will push a new commit
# to update the spelling metadata.
#
# `with.experimental_apply_changes_via_bot`
# Tells the action to support and generate messages that enable it
# to make a commit to update the spelling metadata.
#
# `with.ssh_key`
# In order to trigger workflows when the commit is made, you can provide a
# secret (typically, a write-enabled github deploy key).

If you want to debug code in the Cascadia package via Visual Studio, your breakpoints will not be hit by default. A tweak is required to the *CascadiaPackage* project in order to enable this.
1. Right-click on *CascadiaPackage* in Solution Explorer and select Properties.
2. Change the *Application process* type from *Mixed (Managed and Native)* to *Native Only*.
2. Change the *Application process* type from *Mixed (Managed and Native)* to *Native Only*.
## Popping into the Debugger from Running Code
Sometimes you will encounter a scenario where you need to break into the console or terminal code under the debugger but you cannot, for whatever reason, do so by launching it from the beginning under the debugger. This can be especially useful for debugging tests with TAEF which usually launch through several child processes and modules before hitting your code.
To accomplish this, add a `DebugBreak()` statement somewhere in the code and ensure you have a Post-Mortem debugger set.
**NOTE:** `conhost.exe` already has a provision for a conditional `DebugBreak()` very early in the startup code if it was built in debug mode. Set `HKCU\Console` with `DebugLaunch` as a `REG_DWORD` with the value of `1`.
### Setting Visual Studio as Post Mortem Debugger
Go to `Tools > Options` and then make sure that `Native` is checked as the `Just-In-Time Debugging` provider. (Checking the box, if it is not checked, will require that Visual Studio is launched as Administrator.)
![image](https://user-images.githubusercontent.com/18221333/72091481-1b870100-32c5-11ea-8235-cebb9a383c32.png)
Then when you run something with `DebugBreak()` in it, you will see this:
![image](https://user-images.githubusercontent.com/18221333/72091543-42453780-32c5-11ea-8b4b-83a362eb73df.png)
The top ones will be new instances of the Visual Studios installed on your system. The bottom ones will be the running instances of Visual Studio. You can see in the image that one is open already. If you choose the bottom one, VS will attach straight up as if you F5'd from the solution at the point from the `DebugBreak()`. Step up to get out of the break and back into the code.
### Setting WinDBG as Post Mortem Debugger
From an elevated context (a command prompt or whatnot...), run `windbg /I`. This will install the debugger as Post Mortem.
Then run the thing and it will pop straight into a new WinDBG session. Step up to get out of the break and back into the code.
**Caveat:** If you are on an x64 system, you may need to do `windbg /I` with both the x64 and x86 versions of the debugger to catch all circumstances (like if you're trying to run x86 code.)

If I had to take an educated guess as to what is making us faster than pretty much any other application on Windows at putting your text on the screen... I would say it is because that is literally our only job! Also probably because we are using darn near the oldest and lowest level APIs that Windows has to accomplish this work.

We have one bare, super un-special window with no additional controls attached to it. We get our keys fed into us from just barely above the kernel given that we're processing them from window messages and not from some sort of eventing framework common to pretty much any other more complicated UI framework than ours (WPF, WinForms, UWP, Electron). And we dump our text straight onto the window surface using GDI's [PolyTextOut](https://docs.microsoft.com/en-us/windows/desktop/api/wingdi/nf-wingdi-polytextoutw) with no frills.

# How to build Openconsole
# How to build OpenConsole
Openconsole can be built with Visual Studio or from the command line. There are build scripts for both cmd and PowerShell in /tools.
This repository uses [git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules) for some of its dependencies. To make sure submodules are restored or updated, be sure to run the following prior to building:
```shell
git submodule update --init --recursive
```
OpenConsole.sln may be built from within Visual Studio or from the command-line using a set of convenience scripts & tools in the **/tools** directory:
When using Visual Studio, be sure to set up the path for code formatting. This can be done in Visual Studio by going to Tools > Options > Text Editor > C++ > Formatting and checking "Use custom clang-format.exe file" and choosing the clang-format.exe in the repository at /dep/llvm/clang-format.exe by clicking "browse" right under the check box.
## Building with cmd
### Building in PowerShell
The cmd scripts are set up to emulate a portion of the OS razzle build environment. razzle.cmd is the first script that should be run. bcz.cmd will build clean and bz.cmd should build incrementally.
```powershell
Import-Module .\tools\OpenConsole.psm1
Set-MsBuildDevEnvironment
Invoke-OpenConsoleBuild
```
There are a few additional exported functions (look at their documentation for further details):
- `Invoke-OpenConsoleBuild` - builds the solution. Can be passed msbuild arguments.
- `Invoke-OpenConsoleTests` - runs the various tests. Will run the unit tests by default.
- `Start-OpenConsole` - starts Openconsole.exe from the output directory. x64 is run by default.
- `Debug-OpenConsole` - starts Openconsole.exe and attaches it to the default debugger. x64 is run by default.
- `Invoke-CodeFormat` - uses clang-format to format all c++ files to match our coding style.
### Building in Cmd

## Build with Powershell
## Running & Debugging
Openconsole.psm1 should be loaded with `Import-Module`. From there `Set-MsbuildDevEnvironment` will set up environment variables required to build. There are a few exported functions (look at their documentation for further details):
To debug the Windows Terminal in VS, right click on `CascadiaPackage` (in the Solution Explorer) and go to properties. In the Debug menu, change "Application process" and "Background task process" to "Native Only".
- `Invoke-OpenConsolebuild` - builds the solution. Can be passed msbuild arguments.
- `Invoke-OpenConsoleTests` - runs the various tests. Will run the unit tests by default.

- `Debug-OpenConsole` - starts Openconsole.exe and attaches it to the default debugger. x64 is run by default.
- `Invoke-CodeFormat` - uses clang-format to format all c++ files to match our coding style.
You should then be able to build & debug the Terminal project by hitting <kbd>F5</kbd>.
> 👉 You will _not_ be able to launch the Terminal directly by running the WindowsTerminal.exe. For more details on why, see [#926](https://github.com/microsoft/terminal/issues/926), [#4043](https://github.com/microsoft/terminal/issues/4043)
## Configuration Types

AuditMode is an experimental mode that enables some additional static analysis from CppCoreCheck.
## Updating Nuget package references
Certain Nuget package references in this project, like `Microsoft.UI.Xaml`, must be updated outside of the Visual Studio NuGet package manager. This can be done using the snippet below.
> Note that to run this snippet, you need to use WSL as the command uses `sed`.
To update the version of a given package, use the following snippet
`git grep -z -l $PackageName | xargs -0 sed -i -e 's/$OldVersionNumber/$NewVersionNumber/g'`
where:
- `$PackageName` is the name of the package, e.g. Microsoft.UI.Xaml
- `$OldVersionNumber` is the version number currently used, e.g. 2.3.191217003-prerelease
- `$NewVersionNumber` is the version number you want to migrate to, e.g. 2.4.200117003-prerelease
Example usage:
`git grep -z -l Microsoft.UI.Xaml | xargs -0 sed -i -e 's/2.3.191217003-prerelease/2.4.200117003-prerelease/g'`
## Using .nupkg files instead of downloaded Nuget packages
If you want to use .nupkg files instead of the downloaded Nuget package, you can do this with the following steps:
1. Open the Nuget.config file and uncomment line 8 ("Static Package Dependencies")
2. Create the folder /dep/packages
3. Put your .nupkg files in /dep/packages
4. If you are using different versions than those already being used, you need to update the references as well. How to do that is explained under "Updating Nuget package references".

## Background Images and Icons
Some Terminal settings allow you to specify custom background images and icons. It is recommended that custom images and icons are stored in system-provided folders and are referred to using the correct [URI Schemes](https://docs.microsoft.com/en-us/windows/uwp/app-resources/uri-schemes). URI Schemes provide a way to reference files independent of their physical paths (which may change in the future).

# Formatted Copy
## Abstract
When copying text, the Terminal should provide the option of including formatting. Not all apps that receive text allow for picking which format you want when pasting. The default should be to only copy plain text, based on the response from this poll on Twitter.
![Twitter poll](twitter-poll.png)
## Solution Proposals
A proposal for the right click behavior as well as two user settings proposals are described below. The conclusion the team arrived at is at the bottom under the [Conclusions section](#conclusions).
1. [Settings option 1 - global setting](#settings-option-1---global-setting)
2. [Settings option 2 - key binding argument](#settings-option-2---key-binding-argument)
3. [Right click behavior](#right-click-behavior)
### Settings option 1 - global setting
We could have a global setting that when enabled, would copy formatting to the clipboard on all copy operations.
### Settings option 2 - key binding argument
We could add an argument to the `copy` key binding argument to allow for formatted copying when the user chooses to do so.
### Right click behavior
By default, right clicking to copy would only copy the plain text.
## UI/UX Design
### Settings option 1 - global setting
a. The user could list which kinds of formats they want included when they copy. When right clicking, they would copy with these formats.
`"copyFormats": ["html","rtf","plain"]`
b. We could also just combine html and rtf into a single boolean. Users would either get plain text only (`false`) or all formatting (`true`) onto their clipboard. If this is set to `true`, the default right click behavior is reversed: right clicking copies the formatting.
`"copyFormatting": true`
### Settings option 2 - key binding argument
a. Just like the `trimWhitespace` argument you can add to the `copy` key binding, we could add one for text formatting. This would not change the right click behavior.
`{"command": {"action": "copy", "keepFormatting": true}, "keys": "ctrl+a"}`
b. We could also split out the html and rtf formats. The right click behavior would still stay as default.
`{"command": {"action": "copy", "formats": ["html","rtf","plain"]}, "keys": "ctrl+a"}`
## Capabilities
### Accessibility
This shouldn't affect accessibility.
### Security
This does not affect security.
### Reliability
This does not affect reliability.
### Compatibility
This breaks the existing behavior of always copying the formatting. The justification for breaking this default behavior is in response to the community saying the default should be plain text only.
### Performance, Power, and Efficiency
## Potential Issues
One possible issue is that discovering how to copy the formatting might be difficult to find. We could mitigate this by adding it into the settings.json file and commenting it out.
## Conclusions
The team has decided to have plain text as the default copy behavior and to enable formatted copying with a global setting that accepts a boolean value (settings option 1 - global setting, option b). In the future, we can modify this setting to also accept an array, so the user can specify which formats they would like to copy. Additionally, a key binding can be added to allow for greater flexibility.
## Future considerations
We could always add an additional option if people want more flexibility. For example, if we ship a global setting now, we could ship a key binding later that lets you choose how you want to copy, and vice versa. Additionally, we can add functionality to the global setting that allows for specific formats or styles to be copied.

# Commandline Arguments for the Windows Terminal
## Abstract
This spec outlines the changes necessary for Windows Terminal to support
commandline arguments. These arguments can be used to enable customized launch
scenarios for the Terminal, such as booting directly into a specific profile or
directory.
## Inspiration
Since the addition of the "execution alias" `wt.exe` which enables launching the
Windows Terminal from the commandline, we've always wanted to support arguments
to enable custom launch scenarios. This need was amplified by requests like:
* [#576], which wanted to add jumplist entries for the Windows Terminal, but was
blocked because there was no way of communicating to the Terminal _which_
profile it wanted to launch
* [#1060] - being able to right-click in explorer to "open a Windows Terminal
Here" is great, but would be more powerful if it could also provide options to
open specific profiles in that directory.
* [#2068] - We want the user to be able to (from inside the Terminal) not only
open a new window with the default profile, but also open the new window with
a specific profile.
Additionally, the final design for the arguments was heavily inspired by the
arguments available to `tmux`, which also enables robust startup configuration
through commandline arguments.
## User Stories
Lets consider some different ways that a user or developer might want want to
use commandline arguments, to help guide the design.
1. A user wants to open the Windows Terminal with their default profile.
- This one is easy, it's already provided with simply `wt`.
2. A user wants to open the Windows Terminal with a specific profile from their
list of profiles.
3. A user wants to open the Windows Terminal with their default profile, but
running a different commandline than usual.

## Solution Design
### Proposal 1 - Parameters
Initially, I had considered arguments in the following style:
* `--help`: Display the help message
* `--version`: Display version info for the Windows Terminal
* `--list-profiles`: Display a list of the available profiles
- `--all` to also show "hidden" profiles
- `--verbose`? To also display GUIDs?
* `--open-settings`: Open the settings file
* `--profile <profile name>`: Start with the given profile, by name
* `--guid <profile guid>`: Start with the given profile, by GUID
* `--startingDirectory <path>`: Start in the given directory
* `--initialRows <rows>`, `--initialCols <rows>`: Start with a specific size
* `--initialPosition <x,y>`: Start at an initial location on the screen
* `-- <commandline>`: Start with this commandline instead
However, this style of arguments makes it very challenging to start multiple
tabs or panes simultaneously. How would a user start multiple panes, each with a
different commandline? As configurations become more complex, these commandlines
would quickly become hard to parse and understand for the user.
### Proposal 2 - Commands and Parameters
Instead, we'll try to separate these arguments by their responsibilities. Some
of these arguments cause something to happen, like `help`, `version`, or
`open-settings`. Other arguments act more like modifiers, like for example
`--profile` or `--startingDirectory`, which provide additional information to
the action of _opening a new tab_. Lets try and define these concepts more
clearly.
**Commands** are arguments that cause something to happen. They're provided in
`kebab-case`, and can have some number of optional or required "parameters".
**Parameters** are arguments that provide additional information to "commands".
They can be provided in either a long form or a short form. In the long form,
they're provided in `--camelCase`, with two hyphens preceding the argument
name. In short form, they're provided as just a single character preceded by a
hyphen, like so: `-c`.
Let's enumerate some possible example commandlines, with explanations, to
demonstrate:
### Sample Commandlines

# Start cmd.exe, then split it vertically (with the first taking 70% of it's
# space, and the new pane taking 30%), and run wsl.exe in that pane (user story 13)
wt cmd.exe ; split-pane --target 0 -V -% 30 wsl.exe
wt cmd.exe ; split-pane -% 30 wsl.exe
# Create a new window with the default profile, create a vertical split with the
# default profile, then create a horizontal split in the second pane and run
# "media.exe" (user story 13)
wt new-tab ; split-pane -V ; split-pane --target 1 -H media.exe
wt new-tab ; split-pane -V ; split-pane -t 1 -H media.exe
```
## `wt` Syntax
The `wt` commandline is divided into two main sections: "Options", and "Commands":
`wt [options] [command ; ]...`
Options are a list of flags and other parameters that can control the behavior
of the `wt` commandline as a whole. Commands are a semicolon-delimited list of
commands and arguments for those commands.
If no command is specified in a `command`, then the command is assumed to be a
`new-tab` command by default. So, for example, `wt cmd.exe` is interpreted the
same as `wt new-tab cmd.exe`.
To take this a step further, empty commands surrounded by semicolons will also
be interpreted as `new-tab` commands with the default parameters, so `wt ; ; ;`
can be used to open the windows terminal with **4** new tabs. Effectively, that
commandline expands to `wt new-tab ; new-tab ; new-tab ; new-tab`.
<!--
### Aside: What should the default command be?
These are notes from my draft intentionally left here to help understand the
conclusion that new-tab should be the default command.
Should the default command be `new-window` or `new-tab`?
`new-window` makes sense to take params like `--initialPosition`,
`--initialRows`/`--initialCols`, and _implies_ `new-tab`. However, chained
commands that want to open in the same window _need_ to specify `new-tab`,
otherwise they'll all appear in new windows.
If it's `new-tab`, then how do `--initialRows` (etc) work? `new-tab` generally
_doesn't_ accept those parameters, because it's going to be inheriting the
parent's window size. Do we just ignore them for subsequent invocations? I
suppose that makes sense, once the first tab has set those, then the other tabs
can't really change them.
When dealing with a file full of startup commands, we'll assume all of them are
intended for the given window. So the first `new-tab` in the file will create
the window, and all subsequent `new-tab` commands will create tabs in that same
window.
-->
### Options
#### `--help,-h,-?,/?,`
Runs the `help` command.
#### `--version,-v`
Runs the `version` command.
#### `--session,-s session-id`
Run these commands in the given Windows Terminal session. Enables opening new
tabs in already running Windows Terminal windows. This feature is dependent upon
other planned work landing, so is only provided as an example, of what it might
look like. See [Future Considerations](#Future-Considerations) for more details.
#### `--file,-f configuration-file`
Run these commands in the given Windows Terminal session. Enables opening new
tabs in already running Windows Terminal windows. See [Future
Considerations](#Future-Considerations) for more details.
### Commands
#### `help`
`help`
Display the help message.
#### `version`
`version`
Display version info for the Windows Terminal.
#### `open-settings`
`open-settings [--defaults,-d]`
Open the settings file. If this command is provided alone, it does not open the
terminal window.
**Parameters**:
* `--defaults,-d`: Open the `defaults.json` file instead of the `profiles.json`
file.
#### `list-profiles`
`list-profiles [--all,-A] [--showGuids,-g]`
Displays a list of each of the available profiles. Each profile displays it's
name, separated by newlines.
**Parameters**:
* `--all,-A`: Show all profiles, including profiles marked `"hidden": true`.
* `--showGuids,-g`: In addition to showing names, also list each profile's
guid. These GUIDs should probably be listed _first_ on each line, to make
parsing output easier.
#### `new-tab`
`new-tab [--initialPosition x,y]|[--maximized]|[--fullscreen] [--initialRows rows] [--initialCols cols] [terminal_parameters]`
Opens a new tab with the given customizations. On its _first_ invocation, also
opens a new window. Subsequent `new-tab` commands will all open new tabs in the
same window.
**Parameters**:
* `--initialPosition x,y`: Create the new Windows Terminal window at the given
location on the screen in pixels. This parameter is only used when initially
creating the window, and ignored for subsequent `new-tab` commands. When
combined with any of `--maximized` or `--fullscreen`, an error message will be
displayed to the user, indicating that an invalid combination of arguments was
provided.
* `--initialRows rows`: Create the terminal window with `rows` rows (in
characters). If omitted, uses the value from the user's settings. This
parameter is only used when initially creating the window, and ignored for
subsequent `new-tab` commands. When combined with any of `--maximized` or
`--fullscreen`, an error message will be displayed to the user, indicating
that an invalid combination of arguments was provided.
* `--initialCols cols`: Create the terminal window with `cols` cols (in
characters). If omitted, uses the value from the user's settings. This
parameter is only used when initially creating the window, and ignored for
subsequent `new-tab` commands. When combined with any of `--maximized` or
`--fullscreen`, an error message will be displayed to the user, indicating
that an invalid combination of arguments was provided.
* `[terminal_parameters]`: See [[terminal_parameters]](#terminal_parameters).
#### `split-pane`
`split-pane [--target,-t target-pane] [-H]|[-V] [--percent,-% split-percentage] [terminal_parameters]`
Creates a new pane in the currently focused tab by splitting the given pane
vertically or horizontally.
**Parameters**:
* `--target,-t target-pane`: Creates a new split in the given `target-pane`.
Each pane has a unique index (per-tab) which can be used to identify them.
These indices are assigned in the order the panes were created. If omitted,
defaults to the index of the currently focused pane.
* `-H`, `-V`: Used to indicate which direction to split the pane. `-V` is
"vertically" (think `[|]`), and `-H` is "horizontally" (think `[-]`). If
omitted, defaults to "auto", which splits the current pane in whatever the
larger dimension is. If both `-H` and `-V` are provided, defaults to vertical.
* `--percent,-% split-percentage`: Designates the amount of space that the new
pane should take as a percentage of the parent's space. If omitted, the pane
will take 50% by default.
* `[terminal_parameters]`: See [[terminal_parameters]](#terminal_parameters).
#### `focus-tab`
`focus-tab [--target,-t tab-index]`
Moves focus to a given tab.
**Parameters**:
* `--target,-t tab-index`: moves focus to the tab at index `tab-index`. If omitted,
defaults to `0` (the first tab).
#### `focus-pane`
`focus-pane [--target,-t target-pane]`
Moves focus within the currently focused tab to a given pane.
**Parameters**:
* `--target,-t target-pane`: moves focus to the given `target-pane`. Each pane
has a unique index (per-tab) which can be used to identify them. These
indices are assigned in the order the panes were created. If omitted,
defaults to the index of the currently focused pane (which is effectively a
no-op).
#### `move-focus`
`move-focus [--direction,-d direction]`
Moves focus within the currently focused tab in the given direction.
**Parameters**:
* `--direction,-d direction`: moves focus in the given `direction`. `direction`
should be one of [`left`, `right`, `up`, `down`]. If omitted, does not move
the focus at all (resulting in a no-op).
#### `[terminal_parameters]`
Some of the preceding commands are used to create a new terminal instance.
These commands are listed above as accepting `[terminal_parameters]` as a
parameter. For these commands, `[terminal_parameters]` can be any of the
following:
`[--profile,-p profile-name] [--startingDirectory,-d starting-directory] [commandline]`
* `--profile,-p profile-name`: Use the given profile to open the new tab/pane,
where `profile-name` is the `name` or `guid` of a profile. If `profile-name`
does not match _any_ profiles, uses the default.
* `--startingDirectory,-d starting-directory`: Overrides the value of
`startingDirectory` of the specified profile, to start in `starting-directory`
instead.
* `commandline`: A commandline to replace the default commandline of the
selected profile. If the user wants to use a `;` in this commandline, it
should be escaped as `\;`.
Fundamentally, there's no reason that _all_ the current profile settings
couldn't be overridden by commandline arguments. Practically, it might be
unreasonable to create short form arguments for each and every Profile
property, but the long form would certainly be reasonable.
The arguments listed above represent both special cases of the profile settings
like `guid` and `name`, as well as high priority properties to add as arguments.
* It doesn't really make sense to override `name` or `guid`, so those have been
repurposed as arguments for selecting a profile.
* `commandline` is a bit of a unique case - we're not explicitly using an
argument to identify the start of the commandline here. This is to help avoid
the need to parse and escape arguments to the client commandline.
* `startingDirectory` is a _highly_ requested commandline argument, so that's
been given priority in this spec.
## Implementation Details
Following an investigation performed the week of Nov 18th, 2019, I've determined
that we should be able to use the [CLI11] open-source library to parse
our arguments. We'll need to add some additional logic on top of CLI11 in order
to properly separate commands with `;`, but that's not impossible to achieve.
CLI11 will allow us to parse commandlines as a series of options, with a
possible sub-command that takes its own set of parameters. This functionality
will be used to enable our options & commands style of parameters.
When commands are parsed, each command will build an `ActionAndArgs` that can be
used to tell the terminal what steps to perform on startup. The Terminal already
uses these `ActionAndArgs` to perform actions like opening new tabs, panes,
moving focus, etc.
In my initial investigation, it seemed as though the Terminal did not initialize
the size of child controls initially. This meant that it wasn't possible to
immediately create all the splits and tabs for the Terminal as passed on the
commandline, because they'd open at a size of 0x0. To mitigate this, we'll
handle dispatching these startup actions one at a time, waiting until the
Terminal for an action is initialized or the command is otherwise completed
before dispatching the next one.
This is a perhaps fragile way of handling the initialization. Ideally, there
should be a way to dispatch all the commands _immediately_, before the Terminal
fully initializes, so that the UI pops up in the state as specified in the
commandline. This will be an area of active investigation as implementation is
developed, to make the initialization of many commands as seamless as possible.
### Implementation plan
As this is a very complex feature, there will need to be a number of steps taken
in the codebase to enable this functionality in a way that users are expecting.
The following is a suggestion of the individual changelists that could be made
to iteratively work towards fulling implementing this functionality.
* [x] Refactor `ShortcutAction` dispatching into its own class
- Right now, the `AppKeyBindings` is responsible for triggering all
`ActionAndArgs` events, but only based upon keystrokes while the Terminal is
running. As we'll be re-using `ActionAndArgs` for handling startup events,
we'll need a more generic way of dispatching those events.
* [x] Add a `SplitPane` `ShortcutAction`, with a single parameter `split`,
which accepts either `vertical`, `horizontal`, or `auto`.
- Make sure to convert the legacy `SplitVertical` and `SplitHorizontal` to use
`SplitPane` with that arg set appropriately.
* [x] Add a `TerminalParameters` winrt object to `NewTabArgs` and `SplitPane`
args. `TerminalParameters` will include the following properties:
```c#
runtimeclass TerminalParameters {
String ProfileName;
String ProfileGuid;
String StartingDirectory;
String Commandline;
}
```
- These represent the arguments in `[terminal_parameters]`. When set, they'll
both `newTab` and `splitPane` will accept [`profile`, `guid`, `commandline`,
`startingDirectory`] as optional parameters, and when they're set, they'll
override the default values used when creating a new terminal instance.
- `profile` and `guid` will be used to look up the profile to create by
`name`, `guid`, respectively, as opposed to the default profile.
- The others will override their respective properties from the
`TerminalSettings` created for that profile.
* [x] Add an optional `"percent"` argument to `SplitPane`, that enables a pane
to be split with a specified percent of the parent pane.
* [x] Add support to `TerminalApp` for parsing commandline arguments, and
constructing a list of `ActionAndArgs` based on those commands.
- This will include adding tests that validate a particular commandline
generates the given sequence of `ActionAndArgs`.
- This will _not_ include _performing_ those actions, or passing the
commandline from the `WindowsTerminal` executable to the `TerminalApp`
library for parsing. This change does not add any user-facing functional
behavior, but is self-contained enough that it can be its own changelist,
without depending upon other functionality.
* [ ] When parsing a `new-tab` command, configure the `TerminalApp::AppLogic` to
set some initial state about itself, to handle the `new-tab` arguments
[`--initialPosition`, `--maximized`, `--initialRows`, `--initialCols`]. Only
set this state for the first `new-tab` parsed. These settings will overwrite
the corresponding global properties on launch.
* [ ] When parsing a `help` command or a `list-profiles` command, trigger a
event on `AppLogic`. This event should be able to be handled by
WindowsTerminal (`AppHost`), and used to display a `MessageBox` with the given
text. (see [Potential Issues](##subsystemwindows-or-subsystemconsole) for a
discussion on this).
* [ ] Add support for performing actions passed on the commandline. This
includes:
- Passing the commandline into the `TerminalApp` for parsing.
- Performing `ActionAndArgs` that are parsed by the Terminal.
- At this point, the user should be able to pass the following commands to the
Terminal:
- `new-tab`
- `split-pane`
- `move-focus`
- `focus-tab`
- `open-settings`
- `help`
- `list-profiles`
* [ ] Add a `ShortcutAction` for `FocusPane`, which accepts a single parameter
`index`.
- We'll need to track each `Pane`'s ID as `Pane`s are created, so that we can
quickly switch to the nth `Pane`.
- This is in order to support the `-t,--target` parameter of `split-pane`.
## Capabilities
### Accessibility
As a commandline feature, the accessibility of this feature will largely be tied
to the ability of the commandline environment to expose accessibility
notifications. Both `conhost.exe` and the Windows Terminal already support
basic accessibility patterns, so users using this feature from either of those
terminals will be reliant upon their accessibility implementations.
### Security
As we'll be parsing user input, that's always subject to worries about buffer
length, input values, etc. Fortunately, most of this should be handled for us by
the operating system, and passed to us as a commandline via `winMain` and
`CommandLineToArgvW`. We should still take extra care in parsing these args.
### Reliability
This change should not have any particular reliability concerns.
### Compatibility
This change should not regress any existing behaviors.
### Performance, Power, and Efficiency
This change should not particularly impact startup time or any of these other categories.
## Potential Issues
### Commandline escaping
Escaping commandlines is notoriously tricky to do correctly. Since we're using
`;` to delimit commands, which might want to also use `;` in the commandline
itself, we'll use `\;` as an escaped `;` within the commandline. This is an area
we've been caught in before, so extensive testing will be necessary to make sure
this works as expected.
Painfully, powershell uses `;` as a separator between commands as well. So, if
someone wanted to call a `wt` commandline in powershell with multiple commands,
the user would need to also escape those semicolons for powershell first. That
means a command like ```wt new-tab ; split-pane``` would need to be ```wt new-tab
`; split-pane``` in powershell, and ```wt new-tab ; split-pane commandline \; with
\; semicolons``` would need to become ```wt new-tab `; split-pane commandline \`;
with \`; semicolons```, using ```\`;``` to first escape the semicolon for
powershell, then the backslash to escape it for `wt`.
Alternatively, the user could choose to escape the semicolons with quotes
(either single or double), like so: ```wt new-tab ';' split-pane "commandline \;
with \; semicolons"```.
This would get a little ridiculous when using powershell commands that also have
semicolons possible escaped within them:
```powershell
wt.exe ";" split-pane "powershell Write-Output 'Hello World' > foo.txt; type foo.txt"
```
We've decided that although this behavior is uncomfortable in powershell, there
doesn't seem to be any option out there that's _less_ painful. This is a
reasonable option that makes enough logical sense. Users familiar with
powershell will understand the need to escape commandlines like this.
As noted by @jantari:
> PowerShell has the --% (stop parsing) operator, which instructs it to stop
> interpreting anything after it and just pass it on verbatim. So, the

> ```
### `/SUBSYSTEM:Windows` or `/SUBSYSTEM:Console`?
When you create an application on Windows, you must link it as either a Windows
or a Console application. When the application is launched from a commandline
shell as a Windows application, the shell will immediately return to the
foreground of the console, which means that any console output emitted by the
process will be intermixed with the shell. However, if an application is linked
as a Console application, and it's launched from the Start Menu, Run dialog, or
any other context that's _not_ a console, then the OS will _automatically_
create a console to host the commandline application. That means that briefly, a
console window will appear on the screen, even if we decide that we just want to
launch our application's window.
This basically leaves us with two bad scenarios. Either we're a Console
application, and a console window always flashes on screen for every
non-commandline invocation of the Terminal, or we're a Windows application, and
console output we log (including help messages) can get mixed with shell output.
Neither of these are particularly good.
`python` et. al. often ship with _two_ executables, a `python.exe` which is a
Console application, and a `pythonw.exe`, which is a Windows application. This
however has led to [loads of confusion](https://stackoverflow.com/a/30313091),
and even with plentiful documentation, would likely result in users being
confused about what does what. For situations like launching the Terminal in the
CWD of `explorer.exe`, users would need to use `wtw.exe -d .` to prevent the
console window from appearing. However, when calling Windows Terminal from a
commandline environment, users who call `wtw.exe /?` would likely get unexpected
behavior, because they should have instead called `wt.exe /?`.
To avoid this confusion, I propose we follow the example of `msiexec /?`. This
is a Windows application that uses a `MessageBox` to display its help text.
While this is less convenient for users coming exclusively from a commandline
environment, it's also the least bad option available to us.
* It's less confusing than having control returned to the shell
* It's not as bad as forcing the creation of a console window for
non-commandline launches.
* There's precedent for this kind of dialog (we're not inventing a new pattern
here).
### What happens if `new-tab` isn't the first command?
Consider the following commandline:
```sh
wt.exe split-pane -V ; new-tab
```
In the future, maybe we could presume in this case that the commands are
intended for the current Windows Terminal window, though that's not
functionality that will arrive in 1.0. Even when sessions are supported like
that, I'm not sure that when we're parsing a commandline, we'll be able to
know what session we're currently running in. That might make it challenging to
dispatch this kind of command to "the current WT window".
Additionally, what would happen if this was run in a `conhost` window, that
wasn't attached to a Terminal session? We wouldn't be able to tell _the current
session_ to `split-pane`, since there wouldn't be one. What would we do then?
Display an error message somehow?
I don't believe that implying the _current Windows Terminal session_ is the
correct behavior here. Instead we should either:
* Assume that there's an implicit `new-tab` command that's run first, to create
the window, _then_ run `split-pane` in that tab.
* Immediately display an error that the commandline is invalid, and that a
commandline should start with a `new-tab ; `?
In my initial implementation, I resolved this by assuming there was an implicit
`new-tab` command, and that felt right. The team has discussed this, and
concluded that's the correct behavior. In the words of @DHowett-MSFT:
> In favor of "implicit `new-tab`": `wt.exe` without any arguments is _already_
> an implicit `new-window` or `new-tab`; we can't claw back the implicitness and
> ease of use in that one, so I think in the spirit of keeping that going WT
> should automatically do anything necessary to service a command (`wt
> split-pane` should operate in a new tab or new window, etc.)
We should also make sure that when we add support for the `open-settings`
command, that command by itself should not imply a `new-tab`. `wt open-settings`
should simply open the settings in the user's chosen `.json` editor, without
needing to open a terminal window.
## Future considerations
* These are some additional argument ideas which are dependent on other features
that might not land for a long time. These features were still considered as a
part of the design of this solution, though their implementation is purely
hypothetical for the time being.
* Instead of launching a new Windows Terminal window, attach this new
terminal to an existing one. This would require the work outlined in
[#2080], so support a "manager" process that could coordinate sessions
like this.
- This would be something like `wt --session [some-session-id]
[commands]`, where `--session [some-session-id]` would tell us that
`[more-commands]` are intended for the given other session/window.
That way, you could open a new tab in another window with `wt --session
0 cmd.exe` (for example).
* `list-sessions`: A command to display all the active Windows terminal
instances and their session ID's, in a way compatible with the above
command. Again, heavily dependent upon the implementation of [#2080].
* `--elevated`: Should it be possible for us to request an elevated session
of ourselves, this argument could be used to indicate the process should
launch in an _elevated_ context. This is considered in pursuit of [#632].
* `--file,-f configuration-file`: Used for loading a configuration file to
give a list of commands. This file can enable a user to have a re-usable
configuration saved somewhere on their machine. When dealing with a file
full of startup commands, we'll assume all of them are intended for the
given window. So the first `new-tab` in the file will create the window,
and all subsequent `new-tab` commands will create tabs in that same
window.
* In the past we've had requests (like [#756]) for having the terminal start
with multiple tabs/panes by default. This might be a path to enabling that
scenario. One could imagine the `profiles.json` file including a
`defaultConfiguration` property, with a path to a .conf file filled with
commands. We'd parse that file on window creation just the same as if it was
parsed on the commandline. If the user provides a file on the commandline,
we'll just ignore that value from `profiles.json`.
* When working on "New Window", we'll want the user to be able to open a new
window with not only the default profile, but also a specific profile. This
will help us enable that scenario.
* We might want to look into `RegisterArgumentCompleter` in powershell to
enable letting the user auto-complete our args in powershell.
* If we're careful, we could maybe create short form aliases for all the
commands, so the user wouldn't need to type them all out every time. `new-tab`
could become `nt`, `split-pane` becomes `sp`, etc. A commandline could look
like `wt ; sp less some-log.txt ; fp -t 0` then.

_This is a draft spec. It should be considered a work-in-progress._
# Command Palette
## Abstract
This spec covers the addition of a "command palette" to the Windows Terminal.
The Command Palette is a GUI that the user can activate to search for and
execute commands. Beneficially, the command palette allows the user to execute
commands _even if they aren't bound to a keybinding_.
## Inspiration
This feature is largely inspired by the "Command Palette" in text editors like
VsCode, Sublime Text and others.
This spec was initially drafted in [a
comment](https://github.com/microsoft/terminal/issues/2046#issuecomment-514219791)
in [#2046]. That was authored during the annual Microsoft Hackathon, where I
proceeded to prototype the solution. This spec is influenced by things I learned
prototyping.
## Solution Design
First off, for the sake of clarity, we'll rename the `command` of a keybinding
to `action`. This will help keep the mental model between commands and actions
clearer. When deserializing keybindings, we'll include a check for the old
`command` key to migrate it.
We'll introduce a new top-level array to the user settings, under the key
`commands`. `commands` will contain an array of commands, each with the
following schema:
```js
{
"name": string,
"action": string,
"icon": string
"args": object?,
}
```
Command names should be human-friendly names of actions, though they don't need
to necessarily be related to the action that it fires. For example, a command
with `newTab` as the action could have `"Open New Tab"` as the name.
The command will be parsed into a new class, `Command`:
```c++
class Command
{
winrt::hstring Name();
winrt::TerminalApp::ActionAndArgs ActionAndArgs();
winrt::hstring IconSource();
}
```
We'll add another structure in GlobalAppSettings to hold all these actions. It
will just be a `std::vector<Command>` in `GlobalAppSettings`.
We'll need app to be able to turn this vector into a `ListView`, or similar, so
that we can display this list of actions. Each element in the view will be
intrinsically associated with the `Command` object it's associated with. In
order to support this, we'll make `Command` a winrt type that implements
`Windows.UI.Xaml.Data.INotifyPropertyChanged`. This will let us bind the XAML
element to the winrt type.
When an element is clicked on in the list of commands, we'll raise the event
corresponding to that `ShortcutAction`. `AppKeyBindings` already does a great
job of dispatching `ShortcutActions` (and their associated arguments), so we'll
re-use that. We'll pull the basic parts of dispatching `ActionAndArgs`
callbacks into another class, `ShortcutActionDispatch`, with a single
`PerformAction(ActionAndArgs)` method (and events for each action).
`AppKeyBindings` will be initialized with a reference to the
`ShortcutActionDispatch` object, so that it can call `PerformAction` on it.
Additionally, by having a singular `ShortcutActionDispatch` instance, we won't
need to re-hook up the ShortcutAction keybindings each time we re-load the
settings.
In `App`, when someone clicks on an item in the list, we'll get the
`ActionAndArgs` associated with that list element, and call PerformAction on
the app's `ShortcutActionDispatch`. This will trigger the event handler just the
same as pressing the keybinding.
### Commands for each profile?
[#3879] Is a request for being able to launch a profile directly, via the
command palette. Essentially, the user will type the name of a profile, and hit
enter to launch that profile. I quite like this idea, but with the current spec,
this won't work great. We'd need to manually have one entry in the command
palette for each profile, and every time the user adds a profile, they'd need to
update the list of commands to add a new entry for that profile as well.
This is a fairly complicated addition to this feature, so I'd hold it for
"Command Palette v2", though I believe it's solution deserves special
consideration from the outset.
I suggest that we need a mechanism by which the user can specify a single
command that would be expanded to one command for every profile in the list of
profiles. Consider the following sample:
```json
"commands": [
{
"expandOn": "profiles",
"icon": "${profile.icon}",
"name": "New Tab with ${profile.name}",
"command": { "action": "newTab", "profile": "${profile.name}" }
},
{
"expandOn": "profiles",
"icon": "${profile.icon}",
"name": "New Vertical Split with ${profile.name}",
"command": { "action": "splitPane", "split":"vertical", "profile": "${profile.name}" }
}
],
```
In this example:
* The `"expandOn": "profiles"` property indicates that each command should be
repeated for each individual profile.
* The `${profile.name}` value is treated as "when expanded, use the given
profile's name". This allows each command to use the `name` and `icon`
properties of a `Profile` to customize the text of the command.
To ensure that this works correctly, we'll need to make sure to expand these
commands after all the other settings have been parsed, presumably in the
`Validate` phase. If we do it earlier, it's possible that not all the profiles
from various sources will have been added yet, which would lead to an incomplete
command list.
We'll need to have a placeholder property to indicate that a command should be
expanded for each `Profile`. When the command is first parsed, we'll leave the
format strings `${...}` unexpanded at this time. Then, in the validate phase,
when we encounter a `"expandOn": "profiles"` command, we'll remove it from the
list, and use it as a prototype to generate commands for every `Profile` in our
profiles list. We'll do a string find-and-replace on the format strings to
replace them with the values from the profile, before adding the completed
command to the list of commands.
Of course, how does this work with localization? Considering the [section
below](#localization), we'd update the built-in commands to the following:
```json
"commands": [
{
"iterateOn": "profiles",
"icon": "${profile.icon}",
"name": { "key": "NewTabWithProfileCommandName" },
"command": { "action": "newTab", "profile": "${profile.name}" }
},
{
"iterateOn": "profiles",
"icon": "${profile.icon}",
"name": { "key": "NewVerticalSplitWithProfileCommandName" },
"command": { "action": "splitPane", "split":"vertical", "profile": "${profile.name}" }
}
],
```
In this example, we'll look up the `NewTabWithProfileCommandName` resource when
we're first parsing the command, to find a string similar to `"New Tab with
${profile.name}"`. When we then later expand the command, we'll see the
`${profile.name}` bit from the resource, and expand that like we normally would.
Trickily, we'll need to make sure to have a helper for replacing strings like
this that can be used for general purpose arg parsing. As you can see, the
`profile` property of the `newTab` command also needs the name of the profile.
Either the command validation will need to go through and update these strings
manually, or we'll need another of enabling these `IActionArgs` classes to fill
those parameters in based on the profile being used. Perhaps the command
pre-expansion could just stash the json for the action, then expand it later?
This implementation detail is why this particular feature is not slated for
inclusion in an initial Command Palette implementation.
## UI/UX Design
We'll add another action that can be used to toggle the visibility of the
command palette. Pressing that keybinding will bring up the command palette.
When the command palette appears, we'll want it to appear as a single overlay
over all of the panes of the Terminal. The drop-down will be centered
horizontally, dropping down from the top (from the tab row). When commands are
entered, it will be implied that they are delivered to the focused terminal
pane. This will help avoid two problematic scenarios that could arise from
having the command palette attache to a single pane:
* When attached to a single pane, it might be very easy for the UI to quickly
become cluttered, especially at smaller pane sizes.
* This avoids the "find the overlay problem" which is common in editors like
VS where the dialog appears attached to the active editor pane.
The palette will consist of two main UI elements: a text box for searching for
commands, and a list of commands.
The list of commands will be populated with all the commands by default. Each
command will appear like a `MenuFlyoutItem`, with an icon at the left (if it has
one) and the name visible. When opened, the palette will automatically highlight
the first entry in the list.
The user can navigate the list of entries with the arrow keys. Hitting enter
will close the palette and execute the action that's highlighted. Hitting escape
will dismiss the palette, returning control to the terminal. When the palette is
closed for any reason (executing a command, dismissing with either escape or the
`toggleCommandPalette` keybinding), we'll clear out any search text from the
palette, so the user can start fresh again.
We'll also want to enable the command palette to be filterable, so that the user
can type the name of a command, and the command palette will automatically
filter the list of commands. This should be more powerful then just a simple
string compare - the user should be able to type a search string, and get all
the commands that match a "fuzzy search" for that string. This will allow users
to find the command they're looking for without needing to type the entire
command.
For example, consider the following list of commands:
```json
"commands": [
{ "icon": null, "name": "New Tab", "action": "newTab" },
{ "icon": null, "name": "Close Tab", "action": "closeTab" },
{ "icon": null, "name": "Close Pane", "action": "closePane" },
{ "icon": null, "name": "[-] Split Horizontal", "action": "splitHorizontal" },
{ "icon": null, "name": "[ | ] Split Vertical", "action": "splitVertical" },
{ "icon": null, "name": "Next Tab", "action": "nextTab" },
{ "icon": null, "name": "Prev Tab", "action": "prevTab" },
{ "icon": null, "name": "Open Settings", "action": "openSettings" },
{ "icon": null, "name": "Open Media Controls", "action": "openTestPane" }
],
```
* "open" should return both "**Open** Settings" and "**Open** Media Controls".
* "Tab" would return "New **Tab**", "Close **Tab**", "Next **Tab**" and "Prev
**Tab**".
* "P" would return "Close **P**ane", "[-] S**p**lit Horizontal", "[ | ]
S**p**lit Vertical", "**P**rev Tab", "O**p**en Settings" and "O**p**en Media
Controls".
* Even more powerfully, "sv" would return "[ | ] Split Vertical" (by matching
the **S** in "Split", then the **V** in "Vertical"). This is a great example
of how a user could execute a command with very few keystrokes.
As the user types, we should **bold** each matching character in the command
name, to show how their input correlates to the results on screen.
## Capabilities
### Accessibility
As the entire command palette will be a native XAML element, it'll automatically
be hooked up to the UIA tree, allowing for screen readers to naturally find it.
* When the palette is opened, it will automatically receive focus.
* The terminal panes will not be able to be interacted with while the palette
is open, which will help keep the UIA tree simple while the palette is open.
### Security
This should not introduce any _new_ security concerns. We're relying on the
security of jsoncpp for parsing json. Adding new keys to the settings file
will rely on jsoncpp's ability to securely parse those json values.
### Reliability
We'll need to make sure that invalid commands are ignored. A command could be
invalid because:
* it has a null `name`, or a name with the empty string for a value.
* it has a null `action`, or an action specified that's not an actual
`ShortcutAction`.
We'll ignore invalid commands from the user's settings, instead of hard
crashing. I don't believe this is a scenario that warrants an error dialog to
indicate to the user that there's a problem with the json.
### Compatibility
We will need to define default _commands_ for all the existing keybinding
commands. With #754, we could add all the actions (that make sense) as commands
to the commands list, so that everyone wouldn't need to define them manually.
### Performance, Power, and Efficiency
We'll be adding a few extra XAML elements to our tree which will certainly
increase our runtime memory footprint while the palette is open.
We'll additionally be introducing a few extra json values to parse, so that could
increase our load times (though this will likely be negligible).
## Potential Issues
This will first require the work in [#1205] to work properly. Right now we
heavily lean on the "focused" element to determine which terminal is "active".
However, when the command palette is opened, focus will move out of the terminal
control into the command palette, which leads to some hard to debug crashes.
Additionally, we'll need to ensure that the "fuzzy search" algorithm proposed
above will work for non-english languages, where a single character might be
multiple `char`s long. As we'll be using a standard XAML text box for input, we
won't need to worry about handling the input ourselves.
### Localization
Because we'll be shipping a set of default commands with the terminal, we should
make sure that list of commands can be localizable. Each of the names we'll give
to the commands should be locale-specific.
To facilitate this, we'll use a special type of object in JSON that will let us
specify a resource name in JSON. We'll use a syntax like the following to
suggest that we should load a string from our resources, as opposed to using the
value from the file:
```json
"commands": [
{ "icon": null, "name": { "key": "NewTabCommandName" }, "action": "newTab" },
{ "icon": null, "name": { "key": "CloseTabCommandKey" }, "action": "closeTab" },
{ "icon": null, "name": { "key": "ClosePaneCommandKey" }, "action": "closePane" },
{ "icon": null, "name": { "key": "SplitHorizontalCommandKey" }, "action": "splitHorizontal" },
{ "icon": null, "name": { "key": "SplitVerticalCommandKey" }, "action": "splitVertical" },
{ "icon": null, "name": { "key": "NextTabCommandKey" }, "action": "nextTab" },
{ "icon": null, "name": { "key": "PrevTabCommandKey" }, "action": "prevTab" },
{ "icon": null, "name": { "key": "OpenSettingsCommandKey" }, "action": "openSettings" },
],
```
We'll check at parse time if the `name` property is a string or an object. If
it's a string, we'll treat that string as the literal text. Otherwise, if it's
an object, we'll attempt to use the `key` property of that object to look up a
string from our `ResourceDictionary`. This way, we'll be able to ship localized
strings for all the built-in commands, while also allowing the user to easily
add their own commands.
During the spec review process, we considered other options for localization as
well. The original proposal included options such as having one `defaults.json`
file per-locale, and building the Terminal independently for each locale. Those
were not really feasible options, so we instead settled on this solution, as it
allowed us to leverage the existing localization support provided to us by the
platform.
The `{ "key": "resourceName" }` solution proposed here was also touched on in
[#5280].
## Future considerations
* Commands will provide an easy point for allowing an extension to add its
actions to the UI, without forcing the user to bind the extension's actions to
a keybinding
* Also discussed in [#2046] was the potential for adding a command that inputs a
certain commandline to be run by the shell. I felt that was out of scope for
this spec, so I'm not including it in detail. I believe that would be
accomplished by adding a `inputCommand` action, with two args: `commandline`,
a string, and `suppressNewline`, an optional bool, defaulted to false. The
`inputCommand` action would deliver the given `commandline` as input to the
connection, followed by a newline (as to execute the command).
`suppressNewline` would prevent the newline from being added. This would work
relatively well, so long as you're sitting at a shell prompt. If you were in
an application like `vim`, this might be handy for executing a sequence of
vim-specific keybindings. Otherwise, you're just going to end up writing a
commandline to the buffer of vim. It would be weird, but not unexpected.
* Additionally mentioned in [#2046] was the potential for profile-scoped
commands. While that's a great idea, I believe it's out of scope for this
spec.
* Once [#754] lands, we'll need to make sure to include commands for each action
manually in the default settings. This will add some overhead that the
developer will need to do whenever they add an action. That's unfortunate, but
will be largely beneficial to the end user.
* We could theoretically also display the keybinding for a certain command in
the `ListViewItem` for the command. We'd need some way to correlate a
command's action to a keybinding's action. This could be done in a follow-up
task.
* We might want to alter the fuzzy-search algorithm, to give higher precedence
in the results list to commands with more consecutive matching characters.
Alternatively we could give more weight to commands where the search matched
the initial character of words in the command.
- For example: `ot` would give more weight to "**O**pen **T**ab" than
"**O**pen Se**t**tings").
* Another idea for a future spec is the concept of "nested commands", where a
single command has many sub-commands. This would hide the children commands
from the entire list of commands, allowing for much more succinct top-level
list of commands, and allowing related commands to be grouped together.
- For example, I have a text editor plugin that enables rendering markdown to
a number of different styles. To use that command in my text editor, first I
hit enter on the "Render Markdown..." command, then I select which style I
want to render to, in another list of options. This way, I don't need to
have three options for "Render Markdown to github", "Render Markdown to
gitlab", all in the top-level list.
- We probably also want to allow a nested command set to be evaluated at
runtime somehow. Like if we had a "Open New Tab..." command that then had a
nested menu with the list of profiles.
* We may want to add a button to the New Tab Button's dropdown to "Show Command
Palette". I'm hesitant to keep adding new buttons to that UI, but the command
palette is otherwise not highly discoverable.
- We could add another button to the UI to toggle the visibility of the
command palette. This was the idea initially proposed in [#2046].
- For both these options, we may want a global setting to hide that button, to
keep the UI as minimal as possible.
* [#1571] is a request for customizing the "new tab dropdown" menu. When we get
to discussing that design, we should consider also enabling users to add
commands from their list of commands to that menu as well.

# Add Profiles To Jumplist
## Abstract
This spec outlines adding support for launching a profile from the jumplist. The main two points that will be detailed are:
1. Adding jumplist support
2. Adding the ability to open a profile from the jumplist
The profiles available in the jumplist will match the profiles available in the application from the + dropdown. The scope of the jumplist feature is limited to desktop devices.
## Inspiration
The inspiration is to be able to quickly open the terminal with one of the configured profiles.
## Terminology
- Jumplist: This is the menu that appears when the application is right-clicked on the taskbar or the start menu.
## Solution Design
### Overview
The jumplist has to be created/modified during the life-cycle of the application. The following is an outline of the steps to be performed (more details below)
1. Load settings / profiles
2. Create the jumplist with the initial profiles
3. Maintain sync between the jumplist and profiles throughout the life of the application
### Jumplist integration
UWP provides an API to access to the jumplist through the [Windows.UI.StartScreen.JumpList class](https://docs.microsoft.com/en-us/uwp/api/windows.ui.startscreen.jumplist), however from previous attempts [1], the api does not work for the project architecture.
Instead, we'll use the COM interface [ICustomDestinationList](https://docs.microsoft.com/en-us/windows/desktop/api/shobjidl_core/nn-shobjidl_core-icustomdestinationlist) [2] directly to create the jumplist. Since we are using Win32 apis, the work should be done in the `WindowsTerminal` project.
Using `ICustomDestinationList` is straightforward with a few additions discussed in this section [below](#Implementation-notes). Resources for using the jumplist can be found [here](https://msdn.microsoft.com/en-us/library/windows/desktop/gg281362.aspx) and [here](https://www.codeproject.com/Articles/36561/Windows-7-Goodies-in-C-Jump-Lists).
The basic overview:
1. Get an instance of the `ICustomDestinationList` COM object
2. Call `ICustomDestinationList.BeginList`
3. Create an `IObjectCollection` COM object
4. Create `IShellLink` COM objects for each profile and add them to the `IObjectCollection`
5. Add the `IObjectCollection` to the `ICustomDestinationList`
6. Call `ICustomDestination.CommitList`
Note that the jumplist is replaced each time, instead of being updated.
#### Approach
One approach is to wrap the COM interfaces in a jumplist class and use that to add and remove items.
#### What if there are multiple instances of the terminal application?
There maybe multiple instances trying to update the jumplist at the same time.
### Adding profiles to the jumplist
To add the profiles to the jumplist there are some prerequisites that are needed
- Be able to access settings / profiles from the `WindowsTerminal` project.
- Detect when profiles are modified
- Created: Add a new profile to the jumplist when a new profile is created by the user
- Deleted: Remove the profile from the jumplist when the profile is removed by the user
- Modified: We'll have to sync profile name changes / icon changes with the jump list
There are also different "categories" that we could add the profiles to. A jumplist can have items in a system category such as `Recent` or `Frequent` or a custom category. Jumplist items can also be a task. The difference between adding an item to a category or the task list is that items in a category can be `pinned` and `removed` from the jumplist by the user. Here is a summary of the two from the documentation [2]:
- `Destinations can be files, folders, websites, or other content-based items, but are not necessarily file-backed. Destinations can be thought of as things or nouns`
- `Tasks are common actions performed in an application that apply to all users of that application regardless of an individual's usage patterns. Tasks can be thought of as actions or verbs`
Following this, it would be more appropriate to add the profiles to the `Tasks` list as we are launching a profile. Essentially each item in the jumplist will be a shortcut that opens the terminal and provides command line arguments.
#### Implementation notes
When specifying the icon to use in the `IShellLink` object, it does not appear to be able to read `ms-appx://` URIs such as ones for the default profile icons and also only able to read `.ico` files. The way that the UWP api is able to do it is by adding additional `PropertyKey`s to the `IShellLink` object [3]. Using these tools [JumpList](https://github.com/EricZimmerman/JumpList) and [Lnk Explorer](https://github.com/EricZimmerman/LECmd), we can examine what is different with UWP jumplists. When we examine the `.lnk` items that the jumplist uses, we can see that additional properties are added to the property store.

### Launching the terminal from the jumplist
The jumplist will launch the terminal by calling the executable alias `wt.exe` with arguments to indicate the profile. The command line arguments to use are tracked in issue [#607](https://github.com/microsoft/terminal/issues/607)
## UI/UX Design
No UI changes are needed. The jumplist is provided by Windows.
### Localization
Depending on how the jump list items will be worded.
### Profile order
The order of the profiles in the jumplist should match the order within the application.
## Capabilities
### Accessibility
Will be provided by what Windows supports for jump lists
### Security
Should not introduce any new security issues
### Reliability
Should not introduce any new reliability issues
### Compatibility
Will have to add the ability to get notified of changes to the profile settings.
### Performance, Power, and Efficiency
The jumplist will have to be saved each time a profile change occurs but the frequency would be expected to be low.
## Potential Issues
#### Should it open a new instance of the terminal or open in a new tab?
#### What should happen if a non existant profile is launched
The jumplist is only updated when the application is running so the profiles could be modified or deleted outside and the jumplist will not be updated. Handling will be done by whatever handles the command line parsing.
## Future considerations
Other things could potentially be added to the jumplist other than profiles.

# Using the `wt.exe` Commandline
As of [#4023], the Windows Terminal now supports accepting arguments on the
commandline, to enable launching the Terminal in a non-default configuration.
This document serves as a reference for all the parameters you can currently
pass, and gives some examples of how to use the `wt` commandline.
> NOTE: If you're running the Terminal built straight from the repo, you'll need
> to use `wtd.exe` and `wtd` instead of `wt.exe` and `wt`.
1. [Commandline Reference](#Reference)
1. [Commandline Examples](#Examples)
## Reference
### Options
#### `--help,-h,-?,/?,`
Display the help message.
## Subcommands
#### `new-tab`
`new-tab [terminal_parameters]`
Opens a new tab with the given customizations. On its _first_ invocation, also
opens a new window. Subsequent `new-tab` commands will all open new tabs in the
same window. <sup>[[1](#footnote-1)]</sup>
**Parameters**:
* `[terminal_parameters]`: See [[terminal_parameters]](#terminal_parameters).
#### `split-pane`
`split-pane [-H,--horizontal|-V,--vertical] [terminal_parameters]`
Creates a new pane in the currently focused tab by splitting the given pane
vertically or horizontally. <sup>[[1](#footnote-1)]</sup>
**Parameters**:
* `-H,--horizontal`, `-V,--vertical`: Used to indicate which direction to split
the pane. `-V` is "vertically" (think `[|]`), and `-H` is "horizontally"
(think `[-]`). If omitted, defaults to "auto", which splits the current pane
in whatever the larger dimension is. If both `-H` and `-V` are provided,
defaults to vertical.
* `[terminal_parameters]`: See [[terminal_parameters]](#terminal_parameters).
#### `focus-tab`
`focus-tab [--target,-t tab-index]|[--next,-n]|[--previous,-p]`
Moves focus to a given tab.
**Parameters**:
* `--target,-t tab-index`: moves focus to the tab at index `tab-index`. If
omitted, defaults to `0` (the first tab). Will display an error if combined
with either of `--next` or `--previous`.
* `-n,--next`: Move focus to the next tab. Will display an error if combined
with either of `--previous` or `--target`.
* `-p,--previous`: Move focus to the previous tab. Will display an error if
combined with either of `--next` or `--target`.
#### `[terminal_parameters]`
Some of the preceding commands are used to create a new terminal instance.
These commands are listed above as accepting `[terminal_parameters]` as a
parameter. For these commands, `[terminal_parameters]` can be any of the
following:
`[--profile,-p profile-name] [--startingDirectory,-d starting-directory] [commandline]`
* `--profile,-p profile-name`: Use the given profile to open the new tab/pane,
where `profile-name` is the `name` or `guid` of a profile. If `profile-name`
does not match _any_ profiles, uses the default.
* `--startingDirectory,-d starting-directory`: Overrides the value of
`startingDirectory` of the specified profile, to start in `starting-directory`
instead.
* `commandline`: A commandline to replace the default commandline of the
selected profile. If the user wants to use a `;` in this commandline, it
should be escaped as `\;`.
### Notes
* <span id="footnote-1"></span> [1]: If you try to run a `wt` commandline while running in a Windows Terminal window, the commandline will _always_ create a new window by default. Being able to run `wt` commandlines in the _current_ window is planned in the future - for more information, refer to [#4472].
## Examples
### Open Windows Terminal in the current directory
```powershell
wt -d .
```
This will launch a new Windows Terminal window in the current working directory.
It will use your default profile, but instead of using the `startingDirectory`
property from that it will use the current path. This is especially useful for
launching the Windows Terminal in a directory you currently have open in an
`explorer.exe` window.
### Opening with multiple panes
If you want to open with multiple panes in the same tab all at once, you can use
the `split-pane` command to create new panes.
Consider the following commandline:
```powershell
wt ; split-pane -p "Windows PowerShell" ; split-pane -H wsl.exe
```
This creates a new Windows Terminal window with one tab, and 3 panes:
* `wt`: Creates the new tab with the default profile
* `split-pane -p "Windows PowerShell"`: This will create a new pane, split from
the parent with the default profile. This pane will open with the "Windows
PowerShell" profile
* `split-pane -H wsl.exe`: This will create a third pane, split _horizontally_
from the "Windows PowerShell" pane. It will be running the default profile,
and will use `wsl.exe` as the commandline (instead of the default profile's
`commandline`).
### Using multiple commands from PowerShell
The Windows Terminal uses the semicolon character `;` as a delimiter for
separating subcommands in the `wt` commandline. Unfortunately, `powershell` also
uses `;` as a command separator. To work around this you can use the following
tricks to help run multiple wt sub commands from powershell. In all the
following examples, we'll be creating a new Terminal window with three panes -
one running `cmd`, one with `powershell`, and a last one running `wsl`.
In each of the following examples, we're using the `Start-Process` command to
run `wt`. For more information on why we're using `Start-Process`, see ["Using
`start`"](#using-start) below.
#### Single quoted parameters (if you aren't calculating anything):
In this example, we'll wrap all the parameters to `wt` in single quotes (`'`)
```PowerShell
start wt 'new-tab "cmd"; split-pane -p "Windows PowerShell" ; split-pane -H wsl.exe'
```
#### Escaped quotes (if you need variables):
If you'd like to pass a value contained in a variable to the `wt` commandline,
instead use the following syntax:
```PowerShell
$ThirdPane = "wsl.exe"
start wt "new-tab cmd; split-pane -p `"Windows PowerShell`" ; split-pane -H $ThirdPane"
```
Note the usage of `` ` `` to escape the double-quotes (`"`) around "Windows
Powershell" in the `-p` parameter to the `split-pane` sub-command.
#### Using `start`
All the above examples explicitly used `start` to launch the Terminal.
In the following examples, we're going to not use `start` to run the
commandline. Instead, we'll try two other methods of escaping the commandline:
* Only escaping the semicolons so that `powershell` will ignore them and pass
them straight to `wt`.
* Using `--%`, so powershell will treat the rest of the commandline as arguments
to the application.
```PowerShell
wt new-tab "cmd" `; split-pane -p "Windows PowerShell" `; split-pane -H wsl.exe
```
```Powershell
wt --% new-tab cmd ; split-pane -p "Windows PowerShell" ; split-pane -H wsl.exe
```
In both these examples, the newly created Windows Terminal window will create
the window by correctly parsing all the provided commandline arguments.
However, these methods are _not_ recommended currently, as Powershell will wait
for the newly-created Terminal window to be closed before returning control to
Powershell. By default, Powershell will always wait for Windows Store
applications (like the Windows Terminal) to close before returning to the
prompt. Note that this is different than the behavior of `cmd`, which will return
to the prompt immediately. See
[Powershell/PowerShell#9970](https://github.com/PowerShell/PowerShell/issues/9970)
for more details on this bug.

### Notes for Future Maintainers
This was originally imported by @miniksa in January 2020.
The provenance information (where it came from and which commit) is stored in the file `cgmanifest.json` in the same directory as this readme.
Please update the provenance information in that file when ingesting an updated version of the dependent library.
That provenance file is automatically read and inventoried by Microsoft systems to ensure compliance with appropiate governance standards.
## What should be done to update this in the future?
1. Go to chromium/chromium repository on GitHub.
2. Take the entire contents of the base/numerics directory wholesale and drop it in the base/numerics directory here.
3. Don't change anything about it.
4. Validate that the license in the root of the repository didn't change and update it if so. It is sitting in the same directory as this readme.
If it changed dramatically, ensure that it is still compatible with our license scheme. Also update the NOTICE file in the root of our repository to declare the third-party usage.
5. Submit the pull.

# `base/numerics`
This directory contains a dependency-free, header-only library of templates
providing well-defined semantics for safely and performantly handling a variety
of numeric operations, including most common arithmetic operations and
conversions.
The public API is broken out into the following header files:
* `checked_math.h` contains the `CheckedNumeric` template class and helper
functions for performing arithmetic and conversion operations that detect
errors and boundary conditions (e.g. overflow, truncation, etc.).
* `clamped_math.h` contains the `ClampedNumeric` template class and
helper functions for performing fast, clamped (i.e. [non-sticky](#notsticky)
saturating) arithmetic operations and conversions.
* `safe_conversions.h` contains the `StrictNumeric` template class and
a collection of custom casting templates and helper functions for safely
converting between a range of numeric types.
* `safe_math.h` includes all of the previously mentioned headers.
*** aside
**Note:** The `Numeric` template types implicitly convert from C numeric types
and `Numeric` templates that are convertable to an underlying C numeric type.
The conversion priority for `Numeric` type coercions is:
* `StrictNumeric` coerces to `ClampedNumeric` and `CheckedNumeric`
* `ClampedNumeric` coerces to `CheckedNumeric`
***
[TOC]
## Common patterns and use-cases
The following covers the preferred style for the most common uses of this
library. Please don't cargo-cult from anywhere else. 😉
### Performing checked arithmetic type conversions
The `checked_cast` template converts between arbitrary arithmetic types, and is
used for cases where a conversion failure should result in program termination:
```cpp
// Crash if signed_value is out of range for buff_size.
size_t buff_size = checked_cast<size_t>(signed_value);
```
### Performing saturated (clamped) arithmetic type conversions
The `saturated_cast` template converts between arbitrary arithmetic types, and
is used in cases where an out-of-bounds source value should be saturated to the
corresponding maximum or minimum of the destination type:
```cpp
// Convert from float with saturation to INT_MAX, INT_MIN, or 0 for NaN.
int int_value = saturated_cast<int>(floating_point_value);
```
### Enforcing arithmetic type conversions at compile-time
The `strict_cast` emits code that is identical to `static_cast`. However,
provides static checks that will cause a compilation failure if the
destination type cannot represent the full range of the source type:
```cpp
// Throw a compiler error if byte_value is changed to an out-of-range-type.
int int_value = strict_cast<int>(byte_value);
```
You can also enforce these compile-time restrictions on function parameters by
using the `StrictNumeric` template:
```cpp
// Throw a compiler error if the size argument cannot be represented by a
// size_t (e.g. passing an int will fail to compile).
bool AllocateBuffer(void** buffer, StrictCast<size_t> size);
```
### Comparing values between arbitrary arithmetic types
Both the `StrictNumeric` and `ClampedNumeric` types provide well defined
comparisons between arbitrary arithmetic types. This allows you to perform
comparisons that are not legal or would trigger compiler warnings or errors
under the normal arithmetic promotion rules:
```cpp
bool foo(unsigned value, int upper_bound) {
// Converting to StrictNumeric allows this comparison to work correctly.
if (MakeStrictNum(value) >= upper_bound)
return false;
```
*** note
**Warning:** Do not perform manual conversions using the comparison operators.
Instead, use the cast templates described in the previous sections, or the
constexpr template functions `IsValueInRangeForNumericType` and
`IsTypeInRangeForNumericType`, as these templates properly handle the full range
of corner cases and employ various optimizations.
***
### Calculating a buffer size (checked arithmetic)
When making exact calculations—such as for buffer lengths—it's often necessary
to know when those calculations trigger an overflow, undefined behavior, or
other boundary conditions. The `CheckedNumeric` template does this by storing
a bit determining whether or not some arithmetic operation has occured that
would put the variable in an "invalid" state. Attempting to extract the value
from a variable in an invalid state will trigger a check/trap condition, that
by default will result in process termination.
Here's an example of a buffer calculation using a `CheckedNumeric` type (note:
the AssignIfValid method will trigger a compile error if the result is ignored).
```cpp
// Calculate the buffer size and detect if an overflow occurs.
size_t size;
if (!CheckAdd(kHeaderSize, CheckMul(count, kItemSize)).AssignIfValid(&size)) {
// Handle an overflow error...
}
```
### Calculating clamped coordinates (non-sticky saturating arithmetic)
Certain classes of calculations—such as coordinate calculations—require
well-defined semantics that always produce a valid result on boundary
conditions. The `ClampedNumeric` template addresses this by providing
performant, non-sticky saturating arithmetic operations.
Here's an example of using a `ClampedNumeric` to calculate an operation
insetting a rectangle.
```cpp
// Use clamped arithmetic since inset calculations might overflow.
void Rect::Inset(int left, int top, int right, int bottom) {
origin_ += Vector2d(left, top);
set_width(ClampSub(width(), ClampAdd(left, right)));
set_height(ClampSub(height(), ClampAdd(top, bottom)));
}
```
*** note
<a name="notsticky"></a>
The `ClampedNumeric` type is not "sticky", which means the saturation is not
retained across individual operations. As such, one arithmetic operation may
result in a saturated value, while the next operation may then "desaturate"
the value. Here's an example:
```cpp
ClampedNumeric<int> value = INT_MAX;
++value; // value is still INT_MAX, due to saturation.
--value; // value is now (INT_MAX - 1), because saturation is not sticky.
```
***
## Conversion functions and StrictNumeric<> in safe_conversions.h
This header includes a collection of helper `constexpr` templates for safely
performing a range of conversions, assignments, and tests.
### Safe casting templates
* `as_signed()` - Returns the supplied integral value as a signed type of
the same width.
* `as_unsigned()` - Returns the supplied integral value as an unsigned type
of the same width.
* `checked_cast<>()` - Analogous to `static_cast<>` for numeric types, except
that by default it will trigger a crash on an out-of-bounds conversion (e.g.
overflow, underflow, NaN to integral) or a compile error if the conversion
error can be detected at compile time. The crash handler can be overridden
to perform a behavior other than crashing.
* `saturated_cast<>()` - Analogous to `static_cast` for numeric types, except
that it returns a saturated result when the specified numeric conversion
would otherwise overflow or underflow. An NaN source returns 0 by
default, but can be overridden to return a different result.
* `strict_cast<>()` - Analogous to `static_cast` for numeric types, except
this causes a compile failure if the destination type is not large
enough to contain any value in the source type. It performs no runtime
checking and thus introduces no runtime overhead.
### Other helper and conversion functions
* `IsValueInRangeForNumericType<>()` - A convenience function that returns
true if the type supplied as the template parameter can represent the value
passed as an argument to the function.
* `IsTypeInRangeForNumericType<>()` - A convenience function that evaluates
entirely at compile-time and returns true if the destination type (first
template parameter) can represent the full range of the source type
(second template parameter).
* `IsValueNegative()` - A convenience function that will accept any
arithmetic type as an argument and will return whether the value is less
than zero. Unsigned types always return false.
* `SafeUnsignedAbs()` - Returns the absolute value of the supplied integer
parameter as an unsigned result (thus avoiding an overflow if the value
is the signed, two's complement minimum).
### StrictNumeric<>
`StrictNumeric<>` is a wrapper type that performs assignments and copies via
the `strict_cast` template, and can perform valid arithmetic comparisons
across any range of arithmetic types. `StrictNumeric` is the return type for
values extracted from a `CheckedNumeric` class instance. The raw numeric value
is extracted via `static_cast` to the underlying type or any type with
sufficient range to represent the underlying type.
* `MakeStrictNum()` - Creates a new `StrictNumeric` from the underlying type
of the supplied arithmetic or StrictNumeric type.
* `SizeT` - Alias for `StrictNumeric<size_t>`.
## CheckedNumeric<> in checked_math.h
`CheckedNumeric<>` implements all the logic and operators for detecting integer
boundary conditions such as overflow, underflow, and invalid conversions.
The `CheckedNumeric` type implicitly converts from floating point and integer
data types, and contains overloads for basic arithmetic operations (i.e.: `+`,
`-`, `*`, `/` for all types and `%`, `<<`, `>>`, `&`, `|`, `^` for integers).
However, *the [variadic template functions
](#CheckedNumeric_in-checked_math_h-Non_member-helper-functions)
are the prefered API,* as they remove type ambiguities and help prevent a number
of common errors. The variadic functions can also be more performant, as they
eliminate redundant expressions that are unavoidable with the with the operator
overloads. (Ideally the compiler should optimize those away, but better to avoid
them in the first place.)
Type promotions are a slightly modified version of the [standard C/C++ numeric
promotions
](http://en.cppreference.com/w/cpp/language/implicit_conversion#Numeric_promotions)
with the two differences being that *there is no default promotion to int*
and *bitwise logical operations always return an unsigned of the wider type.*
### Members
The unary negation, increment, and decrement operators are supported, along
with the following unary arithmetic methods, which return a new
`CheckedNumeric` as a result of the operation:
* `Abs()` - Absolute value.
* `UnsignedAbs()` - Absolute value as an equal-width unsigned underlying type
(valid for only integral types).
* `Max()` - Returns whichever is greater of the current instance or argument.
The underlying return type is whichever has the greatest magnitude.
* `Min()` - Returns whichever is lowest of the current instance or argument.
The underlying return type is whichever has can represent the lowest
number in the smallest width (e.g. int8_t over unsigned, int over
int8_t, and float over int).
The following are for converting `CheckedNumeric` instances:
* `type` - The underlying numeric type.
* `AssignIfValid()` - Assigns the underlying value to the supplied
destination pointer if the value is currently valid and within the
range supported by the destination type. Returns true on success.
* `Cast<>()` - Instance method returning a `CheckedNumeric` derived from
casting the current instance to a `CheckedNumeric` of the supplied
destination type.
*** aside
The following member functions return a `StrictNumeric`, which is valid for
comparison and assignment operations, but will trigger a compile failure on
attempts to assign to a type of insufficient range. The underlying value can
be extracted by an explicit `static_cast` to the underlying type or any type
with sufficient range to represent the underlying type.
***
* `IsValid()` - Returns true if the underlying numeric value is valid (i.e.
has not wrapped or saturated and is not the result of an invalid
conversion).
* `ValueOrDie()` - Returns the underlying value. If the state is not valid
this call will trigger a crash by default (but may be overridden by
supplying an alternate handler to the template).
* `ValueOrDefault()` - Returns the current value, or the supplied default if
the state is not valid (but will not crash).
**Comparison operators are explicitly not provided** for `CheckedNumeric`
types because they could result in a crash if the type is not in a valid state.
Patterns like the following should be used instead:
```cpp
// Either input or padding (or both) may be arbitrary sizes.
size_t buff_size;
if (!CheckAdd(input, padding, kHeaderLength).AssignIfValid(&buff_size) ||
buff_size >= kMaxBuffer) {
// Handle an error...
} else {
// Do stuff on success...
}
```
### Non-member helper functions
The following variadic convenience functions, which accept standard arithmetic
or `CheckedNumeric` types, perform arithmetic operations, and return a
`CheckedNumeric` result. The supported functions are:
* `CheckAdd()` - Addition.
* `CheckSub()` - Subtraction.
* `CheckMul()` - Multiplication.
* `CheckDiv()` - Division.
* `CheckMod()` - Modulus (integer only).
* `CheckLsh()` - Left integer shift (integer only).
* `CheckRsh()` - Right integer shift (integer only).
* `CheckAnd()` - Bitwise AND (integer only with unsigned result).
* `CheckOr()` - Bitwise OR (integer only with unsigned result).
* `CheckXor()` - Bitwise XOR (integer only with unsigned result).
* `CheckMax()` - Maximum of supplied arguments.
* `CheckMin()` - Minimum of supplied arguments.
The following wrapper functions can be used to avoid the template
disambiguator syntax when converting a destination type.
* `IsValidForType<>()` in place of: `a.template IsValid<>()`
* `ValueOrDieForType<>()` in place of: `a.template ValueOrDie<>()`
* `ValueOrDefaultForType<>()` in place of: `a.template ValueOrDefault<>()`
The following general utility methods is are useful for converting from
arithmetic types to `CheckedNumeric` types:
* `MakeCheckedNum()` - Creates a new `CheckedNumeric` from the underlying type
of the supplied arithmetic or directly convertible type.
## ClampedNumeric<> in clamped_math.h
`ClampedNumeric<>` implements all the logic and operators for clamped
(non-sticky saturating) arithmetic operations and conversions. The
`ClampedNumeric` type implicitly converts back and forth between floating point
and integer data types, saturating on assignment as appropriate. It contains
overloads for basic arithmetic operations (i.e.: `+`, `-`, `*`, `/` for
all types and `%`, `<<`, `>>`, `&`, `|`, `^` for integers) along with comparison
operators for arithmetic types of any size. However, *the [variadic template
functions
](#ClampedNumeric_in-clamped_math_h-Non_member-helper-functions)
are the prefered API,* as they remove type ambiguities and help prevent
a number of common errors. The variadic functions can also be more performant,
as they eliminate redundant expressions that are unavoidable with the operator
overloads. (Ideally the compiler should optimize those away, but better to avoid
them in the first place.)
Type promotions are a slightly modified version of the [standard C/C++ numeric
promotions
](http://en.cppreference.com/w/cpp/language/implicit_conversion#Numeric_promotions)
with the two differences being that *there is no default promotion to int*
and *bitwise logical operations always return an unsigned of the wider type.*
*** aside
Most arithmetic operations saturate normally, to the numeric limit in the
direction of the sign. The potentially unusual cases are:
* **Division:** Division by zero returns the saturated limit in the direction
of sign of the dividend (first argument). The one exception is 0/0, which
returns zero (although logically is NaN).
* **Modulus:** Division by zero returns the dividend (first argument).
* **Left shift:** Non-zero values saturate in the direction of the signed
limit (max/min), even for shifts larger than the bit width. 0 shifted any
amount results in 0.
* **Right shift:** Negative values saturate to -1. Positive or 0 saturates
to 0. (Effectively just an unbounded arithmetic-right-shift.)
* **Bitwise operations:** No saturation; bit pattern is identical to
non-saturated bitwise operations.
***
### Members
The unary negation, increment, and decrement operators are supported, along
with the following unary arithmetic methods, which return a new
`ClampedNumeric` as a result of the operation:
* `Abs()` - Absolute value.
* `UnsignedAbs()` - Absolute value as an equal-width unsigned underlying type
(valid for only integral types).
* `Max()` - Returns whichever is greater of the current instance or argument.
The underlying return type is whichever has the greatest magnitude.
* `Min()` - Returns whichever is lowest of the current instance or argument.
The underlying return type is whichever has can represent the lowest
number in the smallest width (e.g. int8_t over unsigned, int over
int8_t, and float over int).
The following are for converting `ClampedNumeric` instances:
* `type` - The underlying numeric type.
* `RawValue()` - Returns the raw value as the underlying arithmetic type. This
is useful when e.g. assigning to an auto type or passing as a deduced
template parameter.
* `Cast<>()` - Instance method returning a `ClampedNumeric` derived from
casting the current instance to a `ClampedNumeric` of the supplied
destination type.
### Non-member helper functions
The following variadic convenience functions, which accept standard arithmetic
or `ClampedNumeric` types, perform arithmetic operations, and return a
`ClampedNumeric` result. The supported functions are:
* `ClampAdd()` - Addition.
* `ClampSub()` - Subtraction.
* `ClampMul()` - Multiplication.
* `ClampDiv()` - Division.
* `ClampMod()` - Modulus (integer only).
* `ClampLsh()` - Left integer shift (integer only).
* `ClampRsh()` - Right integer shift (integer only).
* `ClampAnd()` - Bitwise AND (integer only with unsigned result).
* `ClampOr()` - Bitwise OR (integer only with unsigned result).
* `ClampXor()` - Bitwise XOR (integer only with unsigned result).
* `ClampMax()` - Maximum of supplied arguments.
* `ClampMin()` - Minimum of supplied arguments.
The following is a general utility method that is useful for converting
to a `ClampedNumeric` type:
* `MakeClampedNum()` - Creates a new `ClampedNumeric` from the underlying type
of the supplied arithmetic or directly convertible type.

// 1. Integral maximum is always one less than a power of two, so it must be
// truncated to fit the mantissa of the floating point. The direction of
// rounding is implementation defined, but by default it's always IEEE
// floats, which round to nearest and thus result in a value of larger
// magnitude than the integral value.
// Example: float f = UINT_MAX; // f is 4294967296f but UINT_MAX
// // is 4294967295u.
// 2. If the floating point value is equal to the promoted integral maximum
// value, a range check will erroneously pass.
// Example: (4294967296f <= 4294967295u) // This is true due to a precision
// // loss in rounding up to float.
// 3. When the floating point value is then converted to an integral, the
// resulting value is out of range for the target integral type and
// thus is implementation defined.
// Example: unsigned u = (float)INT_MAX; // u will typically overflow to 0.
// To fix this bug we manually truncate the maximum value when the destination
// type is an integral of larger precision than the source floating-point type,
// such that the resulting maximum is represented exactly as a floating point.
