Default to XamlRoot when unable to find a focused object in
DirectKeyEvents
This may not be the most appropriate "fix" for this. Certainly open to
criticism and feedback. We are trapping the alt+space key chord on the
win32 side and forwarding it to the xaml side. There we try to find a
focused object by walking the xaml tree. If we are unable to find a
focused object we return false and do nothing. I suspect that the area
that has focus that prevents this from working normally is on the win32
side. Since we want to handle the system menu anyway and are explicitly
trapping that key combo and forwarding it on I thought this was the best
approach. If we cant find a focused object default to the xaml root.
## Validation Steps Performed
System menu opens as it should.
Closes#14397
Set the padding to the default TabViewHeaderPadding (8,0,0,0), but with
-1 on the bottom. This prevents a small 1px gap that can appear on 150%
scale displays between the tab item and the content. The 1 on top helps
keep
the tab the correct relative height within the tab row.

This PR adds a convenience feature to New-UnpackagedTerminalDistribution
that produces an unpackaged layout from an already-unpacked AppX, like
the one Visual Studio registers.
```powershell
New-UnpackagedTerminalDistribution `
-TerminalLayout path\to\bin\x64\Debug\AppX `
-XamlAppX path\to\xaml\2.8.appx
```
The output item when you build an unpackaged layout is the temp folder
in which the distribution was built. It will not make a zip file for
you.
## Summary of the Pull Request
Add an infobar warning when a non-monospaced font is selected.
## References and Relevant Issues
#13389
## Detailed Description of the Pull Request / Additional comments
I initially had the `IsOpen` property of the infobar bound to the
`ShowAllFonts` checkbox property. However, I felt we could do better by
adding a property for it since there was already a method defined to
inspect whether the selected font was in the `MonoSpaceFontList`.
## Validation Steps Performed
Warning shows up when a non-monospaced font is selected either globally
or on individual profiles. All existing tests continue to pass.

Adds two new commands, `selectOutput` and `selectCommand`. These don't
do much without shell integration enabled, unfortunately. If you do
enable it, however, you can use these commands to quickly navigate the
history to select whole commands (or their output).

This fixes 3 sources for animations:
* `TabView`'s `EntranceThemeTransition` causes tabs to slowly slide in
from the bottom. Removing the transition requires you to override the
entire list of transitions obviously, which is a global change. Nice.
Am I glad I don't need to deal with the complexity of CSS. /s
* `TabBase`, `SettingsTab` and `TerminalTab` were using a lot of
coroutines with `resume_foreground` even though almost none of the
functions are called from background tabs in the first place. This
caused us to miss the initial XAML drawing pass, which resulted in
animations when the tab icons would asynchronously pop into existence.
It also appears as if `resume_foreground`, etc. have a very high CPU
cost attached, which surprises me absolutely not at all given WinRT.
The improvement is difficult to quantify because the run to run
variation is very high. But it seems like this shaves about 10% off
of the ~500ms startup delay on my PC depending on how you measure it.

`WM_ACTIVATE` is sent on window creation, whereas `WM_SHOWWINDOW` is
sent when the window is shown. Before we call `Peasant::ActivateWindow`
in the `WM_ACTIVATE` handler, we try to get the virtual desktop GUID of
our window, but since it's not shown yet during startup, there's also
no GUID that can be retrieved. This results in an error log message and
an all 0 GUID to be sent via `Peasant::ActivateWindow`.
The GUID of the window that actually spawned on the other hand is never
reported until the first time you reactivate it again, leading to a
number of subtle bugs around window activity.
Additionally, this commit fixes a race condition and pointer unsafety,
by pulling all relevant member variables onto the coroutine's stack,
before it yields itself to a background thread.
## Validation Steps Performed
- Set a trace breakpoint on `_peasantNotifyActivateWindow`
- GUID is non-zero ✅

Original description, pre-process model v3:
> This is just the `SHOWDEFAULT` bit from #12979. This seems to also
work now, but I'm PR'ing it separately so it can be a separate revert
from #13811, if it is problematic.
More accurately:
This PR enables terminal windows to use the `wShowCmd` from the
STARTUPINFO passed to `windowsterminal.exe` to set the initial
visibility of the window. We can't just use `SW_SHOWDEFAULT`, because
all the windows are running in the initial process! After the first
window, the subsequent ones would ignore any params passed to their
originating `windowsterminal.exe` processes. To mitigate, we pass that
`wShowCmd` info from the source process, to the actual running terminal
process. That accounts for most of the delta here.
Closes#9053
This doesn't do the same for defterm-initiated connections. This is
because we don't need to! Defterm very explicitly rejects handoff for
minimized console apps. This is probably for the best! I put an attempt
in 66f8b25ec before I forgot that it was filtered long before the
Terminal. NOT doing this for /min saves us all sorts of "what happens if
`start /min cmd` tries to glom?" or "what if someone does `start /min
cmd && start /max cmd` and they glom together?".

This pull request adds the requirement for the shift key to be pressed
in addition to the control key.
References #14810
Implemented in #14873
This is follow up work from my last pull request that was merged that
only required the control key to be pressed to launch the terminal as
admin from the shell context menu. After some discussion it was decided
that the shift key should be required as well as that is the norm on
Windows.
## Validation Steps Performed
Tested all combinations of shift+ctrl and verified that the terminal
only requests elevation when a shift and control key are pressed
together. The shell launches regularly if not.
This fixes the BreadcrumbBar issue that would crash into the debugger
anytime you open the SUI on a second thread.
See #14957.
Maybe also tracked in #15144 - let's have @j4james test when this
merges.
TL;DR: we stopped getting `TabView.TabItemsChanged`. This meant that the
tab view would change its apparent order, but we wouldn't change the
backing tab order.
I'm fixing this by grabbing the index of the tab that starts the drag,
and the index of the tab view item at the end of the drag, and using
that to reorder our backing list.
Closes#15121
Upstream https://github.com/microsoft/microsoft-ui-xaml/issues/8388
Regressed in #15078 - I'm pretty confident about this, since I've got a
1.18.931 build of the Terminal with tear-out, but not MUX 2.8.
The code changes are mostly self-explanatory: Just skip glyphs
that can never be inserted. I implemented it slightly incorrectly
(a newline will be inserted every time you write such a wide glyph),
but it's a niche issue and I think the simplicity of the fix is
more important than its exact correctness.
It also contains a fix for some severe log spam due to
`_PrepareForDoubleByteSequence` complaining in this situation.
The spam is so bad that it freezes the app for a few seconds
during text buffer reflow.
Closes#7416
## Validation Steps Performed
* Open an extra pane and run `TerminalStress.exe` in there
* Resize to 1 column
* Doesn't hang ✅
Hides the cursor when null, shows it when not.
Clear the screen any time the connection is changed.
This prevents the WPF Control from crashing when set back to null, clears
the console and hides the mouse as well.
It sends 3 VT sequences as well now:
1) When the Connection is set to null the cursor is hidden (reflects
what the default state is)
2) When the Connection is set to a value and it was null before we show
the cursor (not a breaking change as requires it to have been null which
previously would cause a crash, except for for set)
3) When the Connection is changed the terminal is reset. A breaking
change officially although not sure if there are use cases where this
behavior is not desired. For added safety we could make sure we are not
being set to the same value we currently are.
None of the ansi commands are needed, users could do it all themselves
as well, the behavior largely seemed natural though. I didn't see any
ansi constants anywhere so they are just hard coded with comments, but
not sure if there is an established better practice.

## Summary of the Pull Request

## Detailed Description of the Pull Request / Additional comments
My understanding of the discussion and intent of the two linked issues
is that this is a more efficient way to implement the copy assignment
operator for Pane.LayoutSizeNode and eliminates the need for the code
block _AssignChildNode. Since both were relatively small changes, I
combined the two in one PR. If that is not desirable, I can separate
them. All existing tests continue to pass.

As discussed in #6507
Newer builds of Windows do this automatically. However, this was spotted
in the wild on 1.18. It's possible the threading changes created a
situation where the OS-side fix no longer applied to us. So let's just
do it manually. It doesn't have any side effects.
I saw this once on Win11, but couldn't repro it this morning when I
tried to add this fix. I'm just gonna assume this worked, despite the
fact that I can't repro it on win11 anymore.

Fixes an issue when using both:
```json
"centerOnLaunch": true,
"firstWindowPreference": "persistedWindowLayout",
```
In this case, the Terminal would ignore the persisted location and still
just center on launch. This has been really annoying while testing
tear-out, as we keep re-opening all my debug windows as a stack on top
of each other.
Looking through this test, I seriously don't understand how this doesn't
work. I mean, I don't really get how it _does_ work, but at this point
in the tests, we've actually established that both `Nihilist.exe` _and_
openconsole are running. From my read, there's no reason these should be
failing at this point.
We previously added a "retry 5 times" bit to this test, in #8534. That
did work back then. So uh, just do that... again?
Moves our `GetWindowLayoutRequested` handler AFTER the xaml island is
started. The `AppHost::_GetWindowLayoutAsync` handler requires us to be
able to work on our UI thread, which requires that we have a
`Dispatcher` ready for us to move to. If we set up this callback in the
ctor, then it is possible for there to be a time slice where
* the monarch creates the peasant for us,
* we get ctor'ed (registering the callback)
* then the monarch attempts to query all _peasants_ for their layout,
coming back to ask us even before XAML has been created.
I believe this was the source of the crash that was reported in a mail
thread. It actually happened to me once while debugging another branch.
Alas, this was realy hard to hit in the first place, so I'm not
_totally_ certain this fixes it.

When win32-input-mode is enabled, we generate an input sequence for both
key down and key up events. However, in the initial implementation the
key up sequence for most keypresses would be faked - they were generated
at the same time as the key down sequence, regardless of when the key
was actually released. After this PR, we'll only generate the key up
sequence once a key has actually been released.
## References and Relevant Issues
The initial implementation of win32-input-mode was in PR #6309.
The spec for win32-input-mode was in PR #5887.
## Validation Steps Performed
I've manually tested this with an app that polls `ReadConsoleInput` in a
loop and logs the results. With this PR applied, I can now see the key
up events as a key is released, rather than when it was first pressed.
When compared with conhost, though, there are some differences. When
typing a shifted key, e.g. `Shift`+`A`, WT generates key down and key up
events for both the `Shift` and the `A`, while conhost only generates
both events for the `Shift` - the `A` won't generate a key up event
unless you release the `Shift` before the `A`. That seems more like a
conhost flaw though.
Another case I tested was the Japanese Microsoft IME, which in conhost
will generate a key down event for the Japanese character being inserted
followed by a key up event for for `Return`. WT generates key up events
for the ASCII characters being typed in the IME, then both a key down
and key up event for the inserted Japanese character, and finally a key
up event for `Return`. Both of those seem weird, but they still appear
to work OK.
The current version of WT actually produces the most sensible behavior
for the IME - it just generates key up and key down events for the
inserted character. But that's only because it's dropping most of the
system generated key up events.
Closes#8440
I have observed the test comment coming back from Helix with `"`

This PR adds support to the About Dialog for checking the store to see
if there's a new version of the Terminal package available. We'll only
do this once per day, per terminal window.
In dev mode, we'll always fake it and say there's an update to `x.y.z`
available.
This also involved pulling all of the About dialog code out into its own
class. All that is goodness.
We don't currently provide a button for _installing_ the update. We just
check. Incremental progress is better than none.

Some of our automated tooling detects this as being a private API that

it's also not *right*.
It's easier for us to just not do it (and save all the code for it!) in
OpenConsole.
This is a revert of the revert of #12979. We mainly reverted that PR
because of an issue where restored windows would grow/shrink slightly on
external displays. It was too close to the ship date for that release,
so we backed it out wholesale (in #13098). I think I've found the real
root of the problem, and fixed it here.
The money diff here from the original PR:
4c08b9a1bc2e90b8284e4d8117d0de400784520f...c34495dcfc19ea67a9f4f9673d422760200683ab.
Basically, I had put the part where we actually handle the creation of
the window into `_AppInitializedHandler`, when we should have left the
window to be created in `_HandleCreateWindow` We create it there,
_hidden_, and then should only _show_ it in `_AppInitializedHandler`.
I'm _NOT_ incorporating the change for #9053. I reverted that bit in
1fac40355. I am too worried about that messing with the phwnd that I
wanted to get that reviewed and committed atomically, separately.

This adds a setting (`compatibility.allowHeadless`) to let the Terminal
keep running even when all windows are closed. This lets hotkeys keep
working, because the Emperor thread is still running, just, without any
windows.
I'm really tempted to invoke the magic "closes" word on #9996, but
honestly, we should also add some sort of support for `wt --headless` or
`wt --hidden` or whatever, before we close that. There's also #13630
which seems imminently doable.

invoke the quakeMode binding and \*presto\*, but that would be an
unnecessarily big gif.

sane `dark`, but the `legacy*` themes are all right there, and given the
same special treatment as the other inbox themes.

Making Conhost pick up codepage from .lnk files.
Because of the wrong assignment order, the Conhost was not picking up
the codepage stored in .lnk shortcut files. This change fixes this issue
by changing the order of the assignment to the correct one.
This is a potential backward compatibility issue.
Since this issue has been present in the codebase for years, this change
runs a high risk of breaking backward compatibility with software that
depends on incorrect behavior.
## Validation Steps Performed
Tested fix manually (using chcp command, making sure each .lnk codepage
was picked up.) against Debug/Release x64 builds with 5 different .lnk
files:
1. Arabic codepage 1256
2. Greek 869
3. Latin2 852
4. Thai 874
5. Traditional Chinese 50229
Ran TAEF tests against Debug/Release x64/x86 with identical results as
main branch.
Tested against invalid codepage numbers by manually manipulating .lnk
file binary. In case of an invalid codepage number, Conhost defaults to
a valid default one, which I assume is expected behavior.

This is a regression caused by 599b550. If I'm reading `stream.cpp`

Upgrading clang-format lead to a few changes in the formatting
of code inside macros. Apart from the upgrade, I've also spent
some time removing all options from .clang-format that are
redundant with `BasedOnStyle: Microsoft`.
This will allow us to share the same fundamental text insertion
logic for both `ResizeTraditional` and `Reflow`, because both
can be implemented with `ROW::CopyRangeFrom`. It also replaces
the `BufferAllocator` struct with a `_allocateBuffer` function
which will help us allocate scratch buffer rows in the future.
Closes#14696
## PR Checklist
* Disable reflow resize in conhost
* Print "zhwik8.txt" - a enwik8.txt equivalent of Chinese Wikipedia
* Run `color 80` in cmd
* Resize windows from 120 to 119 columns
* Wide glyphs disappear and are replaced with whitespace ✅
* Resizing the window to >120 columns adds gray whitespace ✅
On a real VT terminal, most of the control characters that don't do
anything are supposed to be filtered out, and not written to the buffer.
Up to to now, though, we've only been filtering out `NUL`. This PR
extends our control processing to filter the remaining characters that
aren't supposed to be displayed.
We introduced filtering for the `NUL` control in PR #3015.
The are two special cases worth mentioning.
1. The `SUB` control's main purpose is to the cancel a control sequence
that is in progress, but it also needs to output an error character (a
reverse question mark) to the display.
2. The `DEL` control is typically filtered out, but when a 96-character
set is designated, it can sometimes be mapped to a printable glyph that
needs to be displayed.
## Validation Steps Performed
I've manually tested that all the controls that are meant to be filtered
out are no longer being displayed.
I've also extended the existing `NUL` unit test to cover the full set of
controls characters that are supposed to be filtered.
Closes#10786
`til::linear_flat_set` is a primitive hash map with linear probing.
The implementation is slightly complicated due to the use of templates.
I've strongly considered just writing multiple copies of this class,
by hand since the code is indeed fairly trivial but ended up deciding
against it, because this templated approach makes testing easier.
This class is in the order of 10x faster than `std::unordered_map`.
I noticed this bug while resizing my window on my 150% scale display.
Every 3 "snaps" of the window size, it would fail to resize the text
buffer. I found that this occurs, because we convert the swap chain
size from a float into a double, which converts my 597.333313 height
into 597.33331298828125, which then multiplied by 1.5 results in
895.999969482421875. If you just cast this to an integer, it'll
result in a height of 895px instead of the expected 896px.
This PR addresses the issue in two ways:
* Replace casts to integers with `lrint` or `floor`, etc.
* Remove many of the redundant double <> float conversions.
## PR Checklist
* Resizing my window always resizes the text buffer ✅

C++ is a very well balanced and reasonable language, which is why
`static` inside classes means "shared between all instances", whereas
`static` outside of classes means "not shared between all .cpp files".
32 years after this problem was written onto parchment it was fixed with
the introduction of inline variables in C++17, which tell the compiler
to deduplicate variables the same way it deduplicates functions.
It can be costly, difficult, or often impossible to compare two
instances of a struct. This little helper can simplify this.
The underlying idea is that changes in state occur much less often than
the amount of data that's being processed in between. As such, this
helper assumes that _any_ modification to the struct it wraps is a
state change. When you compare the modified instance with another
the comparison operator will then always return false. This makes
state changes potentially more costly, because more state might be
invalidated than was necessary, but on the other hand it makes both,
the code simpler and the fast-path (no state change) much faster.
For instance, let's look at the amount of data that represents a
user's chosen font: It encompasses the font family, size and weight,
font axes (a vector of tuples), dpi and cell height/width overrides.
Comparing all that data, every time the user changes anything, is
fairly complex to code and maintain and costly at runtime, even though
the user will change the only font very seldomly. Instead, we can
optimize for the common case of no font changes occuring and simply
assume that if any font related field changed, all fields changed.
This is exactly what `til::generational` does.
Updates the Terminal to Microsoft.UI.Xaml v2.8.
* MUX 2.8 adds a dependency on WebView2, so we need to include parts of it too.
* See https://github.com/microsoft/microsoft-ui-xaml/pull/7574 for why
we're adding the `.props`
* The TabView thing:
> tl;dr: In >=MUX 2.7, we were updating our tab colors by doing a
"Visual State Dance", as I called it. We'd manually change the
`TabViewItem`'s VisualState to one that it wasn't in, then change it
back to the one it should be in. This seemingly re-applied the new
values of the brushes. However in 2.8, this seemingly didn't work
anymore!
>
> So instead, we do a "Theme Dance", like so:
> ```c++
> const auto& reqTheme = TabViewItem().RequestedTheme();
> TabViewItem().RequestedTheme(ElementTheme::Light);
> TabViewItem().RequestedTheme(ElementTheme::Dark);
> TabViewItem().RequestedTheme(reqTheme);
> ```
> This causes the `ThemeResource`s to be re-evaluated to the new values.
> We never got to the root cause of why this seems different in 2.8. It
literally makes no sense.

Rendering hyperlinks is unneccessarily complex at the moment, because
it requires you to implement `UpdateDrawingBrushes`, manually extract
the hyperlink flag from the given `TextAttribute` and save it until the
next call to `PaintBufferGridLines` which does not get that flag.
This isn't particularly clean as it assumes that `PaintBufferGridLines`
will be called after `UpdateDrawingBrushes` in the first place.
Instead, we can simply pass the hyperlink flag to `UpdateDrawingBrushes`
so that the renderers don't need to deal with this anymore.
## PR Checklist
* Hyperlinks show up with a dotted line ✅
* Hovering hyperlinks underline them ✅
This tool augments `vttest` by adding some things that are specific to
us (like non-VT console attributes), and some things `vttest` is
seemingly too old for (like emojis). I'm planning to add more "pages"

Two PowerShell scripts were added so that developers new to the project
know if they have the wrong version of PowerShell installed.
When first building Terminal, it would continuously fail, and I didn't
really know why. I'm new to both this project and to open source, so
when I saw an error message about "pwsh.exe" not being found I was
confused and didn't know what went wrong. What I didn't know is that
Windows PowerShell and PowerShell Core had different names for
their .exe files, and since I had the latest version of Windows
PowerShell installed, I figured that I was completely set. So, once I
realized that Windows PowerShell (what I had installed) is
powershell.exe and PowerShell Core (what I needed to have installed) is
pwsh.exe, I downloaded PowerShell Core, and it built without issue. So,
in order to help other newbies, I made two scripts, `CheckPSVersion` and
`WindowsCheckPSVersion`, which make sure that PowerShell Core 7.0.0+ is
installed, outputting an error telling the developer to download Core
7.0.0+ if they have Windows PowerShell but not Core. These scripts are
run pre-build courtesy of `Microsoft.Terminal.Settings.ModelLib.vcxproj`
## Validation Steps Performed
Building with both Windows PowerShell and PowerShell core: builds
perfectly, no issues.
Building with Windows PowerShell but not PowerShell core: build fails,
but a nice error prints out that reminds the user to download the
correct version of PowerShell core.

This pull request implements portable mode for Windows Terminal, which
will make side by side deployment of different versions generally more
feasible.
Portable mode was specified in #15032.
There are three broad categories of changes in this PR:
1. Changes to settings loading.
2. A new indicator in the settings UI plus a link to the portable mode
docs.
3. A new application display name, `Terminal (Portable)`, which users
will hopefully include in their bug reports.
It's surprisingly small for how big a deal it is!

## Summary
_In the final chapter of our tale, we present a PR of great
significance. It grants the power to tear tabs from their windows and
create a new window where they may be dropped, one not necessarily of
the Terminal sort. The dimensions of the original window are transferred
to this new abode, and its placement on the screen is determined by the
user's placement of the tab._
_This is the last main chapter of the tear-out saga, and the dawning of
the new age._

## Detailed description
We're really leaning on the existing `RequestNewWindow` event that the
monarch already had - honestly, most of that was so simple that it could
have just been in the parent PRs. We just need to add new support for
passing in a content blob of json, and making sure the Terminal always
uses that over commandline args. Easy enough.
There's a bit of wackiness here in adjusting the positioning just right
so that the new window appears in the right place, but it feels...
pretty good all things considered.
Since the removal of the Win10-specific variant of the Terminal MSIX in
#15031, there has been no officially-sanctioned (or even unofficially
tested!) way to get an unzippable double-click-runnable version of
Windows Terminal.
Due to a quirk in the resource loading system, an unpackaged
distribution of Terminal needs to ship all of XAML's resources and all
of is own resources in a single `resources.pri` file. The tooling to
support this is minimal, and we were previously just coasting by on
Visual Studio's generosity plus how the prerelease distribution of XAML
embedded itself into the consuming package.
This pull request introduces a build phase plus a supporting script (or
three) that produces a ZIP file distribution of Windows Terminal when
given a Terminal MSIX and an XAML AppX.
The three scripts are:
1. A script to merge any number of PRI files and/or PRI dump files (made
with `makepri dump /dt detailed`)
2. A script that specifically merges XAML's resources with Terminal's.
This is necessary because the XAML package emits a couple PRI
resources into Terminal's resources _even when it is not
co-packaged._ We need to remove the conflicting resources.
3. Finally, a script to take a WT and XAML distribution and combine them
-- resources, files, everything -- and strip out the things that we
don't need. This script is an all-in-one that calls the other two and
produces a ZIP file at the end.
The final distribution is named after the PFN
(`Microsoft.WindowsTerminal`, or `...Preview` or `WindowsTerminalDev`),
the version number and the architecture. When expanded, it produces a
directory named `terminal-X.Y.Z.A` (version number.)
I've also added the build script to the release pipeline.
As a treat, this also produces an unpackaged distribution out of every
CI build... that way, contributors can download live deployable copies
of WT Unpackaged to test out their changes. Pretty cool.
Refs #1386
The main purpose of this PR was to merge the `ITerminalApi::LineFeed`
implementations into a shared method in `AdaptDispatch`, and avoid the
VT code path depending on the `AdjustCursorPosition` function (which
could then be massively simplified). This refactoring also fixes some
bugs that existed in the original `LineFeed` implementations.
## References and Relevant Issues
This helps to close the gap between the Conhost and Terminal (#13408).
This improves some of the scrollbar mark bugs mentioned in #11000.
## Detailed Description of the Pull Request / Additional comments
I had initially hoped the line feed functionality could be implemented
entirely within `AdaptDispatch`, but there is still some Conhost and
Terminal-specific behavior that needs to be triggered when we reach the
bottom of the buffer, and the row coordinates are cycled.
In Conhost we need to trigger an accessibility scroll event, and in
Windows Terminal we need to update selection and marker offsets, reset
pattern intervals, and preserve the user's scroll offset. This is now
handled by a new `NotifyBufferRotation` method in `ITerminalApi`.
But this made me realise that the `_EraseAll` method should have been
doing the same thing when it reached the bottom of the buffer. So I've
added a call to the new `NotifyBufferRotation` API from there as well.
And in the case of Windows Terminal, the scroll offset preservation was
something that was also needed for a regular viewport pan. So I've put
that in a separate `_PreserveUserScrollOffset` method which is called
from the `SetViewportPosition` handler as well.
## Validation Steps Performed
Because of the API changes, there were a number of unit tests that
needed to be updated:
- Some of the `ScreenBufferTests` were accessing margin state in the
`SCREEN_INFORMATION` class which doesn't exist anymore, so I had to add
a little helper function which now manually detects the active margins.
- Some of the `AdapterTest` tests were dependent on APIs that no longer
exist, so they needed to be rewritten so they now check the resulting
state rather than expecting a mock API call.
- The `ScrollWithMargins` test in `ConptyRoundtripTests` was testing
functionality that didn't previously work correctly (issue #3673). Now
that it's been fixed, that test needed to be updated accordingly.
Other than getting the unit tests working, I've manually verified that
issue #3673 is now fixed. And I've also checked that the scroll markers,
selections, and user scroll offset are all being updated correctly, both
with a regular viewport pan, as well as when overrunning the buffer.
Closes#3673
_Behold, the penultimate chapter in the saga of tear-out! This
significant update bestows upon the user the power to transport tabs
betwixt Terminal windows. Alas, the drag and drop capabilities of
TabView are not yet refined, so this PR primarily concerns itself with
the intricacies of plumbing. When a tab is extracted and deposited
elsewhere, it is necessary to have the recipient make an inquiry to the
Monarch, who in turn will beseech the sender to transmit the tab
content, akin to the act of moving a tab. Curious it may seem, but the
method has proven effective._
The penultimate tear-out PR. This PR enables the user to move tabs from
one Terminal window to another. The TabView drag/drop APIs have some
rough edges, so this PR is mostly plumbing. When a tab is drag/dropped,
we need to get the recipient to ask the Monarch to ask the sender to
send the tab content, like a MoveTab action. Wacky, but it works.
There's a LONG tail of UX gaps. Those I'm going to track in #14900. It
is more valuable for us to merge this now than to figure out workarounds
immediately.
The next PR will be the last main PR in this saga - in which we enable
dragging a tab out of the window and dropping to create a new window.

* Related to #5000
* Follow-ups get to go in #14900
## Detailed description
As I mentioned, it's mostly plumbing. The order that we get tab drag
events is... unfortunate... for our use case. So we do a lot of sending
`RequestReceiveContentArgs` up and down between windows, just to
communicate who the tab was dropped on to whomever the tab was dragged
from.
There's a diagram for this that I originally put in

Really really though, let's try to avoid nits about the UX at this time.
This PR works with what we've got. Mail threads are percolating. I've
got 19 chapters worth of Hobbit branch names to use for those follow
ups.
_Lo! Harken to me, for I shall divulge the heart of the tab tear-out
saga. Verily, this PR shall bestow upon thee the power to move tabs and
panes between windows by means of pre-defined actions. Though be warned,
it does not yet grant thee the power to drag and drop them as thou
mayest desire. Yet, the same plumbing that underpins this work shall
remain steadfast. Behold, the majority of this undertaking concerns the
elevation of the RequestMoveContent event from the TerminalPage to the
very summit of the Monarch. From thence, a great AttachContent method
shall descend back to the lowest depths. Furthermore, there are minor
revisions to TermControl that shall enable thee to better detach the
content and attach it to a new one._
This is the most important part of the tab tear-out saga. This PR
enables the user to move tabs and panes between windows using
pre-defined actions. It does _not_ enable the user to drag/drop them
yet, but the same fundamental plumbing will still apply. Most of the PR
is plumbing the `RequestMoveContent` event up from the `TerminalPage` up
to the `Monarch`, and then plumbing an `AttachContent` method back down.
There are also small changes to `TermControl` to better support
detaching the content and attaching to a new one.
For testing, I recommend:

When saving and restoring the cursor position with origin mode enabled,
we originally matched the behavior of the early DEC terminals, which
stored the position as an absolute offset. But if the margin boundaries
were changed prior to restoring the position, that could result in the
cursor being outside the margins, potentially with negative coordinates.
Our implementation avoided that bug by clamping the coordinates back
into range, but that's not how DEC ultimately fixed the issue. Starting
with the VT420, they began using relative coordinates (i.e. relative to
the margin origin), so a restored position could never end up negative.
This PR updates our implementation to match that newer behavior.
## Validation Steps Performed
Thank to testing performed by @al20878, we know this was the algorithm
used on the VT420, VT520, and VT525, and I've manually confirmed that
our implementation now matches their behavior.
I've also updated the `CursorSaveRestore` unit test which previously
covered our clamping behavior - it's now being used to confirm that
we're correctly using relative offsets when restoring the cursor.

This adds PR adds a couple foundational functions and classes to make
our TextBuffer more performant and allow us to improve our Unicode
correctness in the future, by getting rid of our dependence on
`OutputCellIterator`. In the future we can then replace the simple
UTF-16 code point iterator with a proper grapheme cluster iterator.
While my focus is technically on Unicode correctness, the ~4x VT
throughput increase in OpenConsole is pretty nice too.
This PR adds:
* A new, simpler ROW iterator (unused in this PR)
* Cursor movement functions (`NavigateToPrevious`, `NavigateToNext`)
They're based on functions that align the cursor to the start/end
of the _current_ cell, so such functions can be added as well.
* `ReplaceText` to write a raw string of text with the possibility to
specify a right margin.
* `CopyRangeFrom` will allow us to make reflow much faster, as it's able
to bulk-copy already measured strings without re-measuring them.

We ship a separate package to Windows 10, which contains a copy of XAML
embedded in it, because of a bug in activating classes from framework
packages while we're elevated.
We did this to avoid wasting disk space on Windows 11 installs (which is
critical given that we're preinstalled in the Windows image.)
The fix for this issue was released in a servicing update in April 2022.
Thanks to KB5011831, we no longer need this workaround!
And finally, this means that we no longer need to depend on a copy of
"pre-release" XAML. We only did that because it would copy all of its
assets into our package.

This PR introduces two new sequences, `DECRQPSR` and `DECRSPS`, which
provide a way for applications to query and restore the presentation
state reports. This includes the tab stop report (`DECTABSR`) and the
cursor information report (`DECCIR`).
One part of the cursor information report contains the character set
designations and mapped G-sets. But we weren't tracking that data in a
way that could easily be reported, so I needed to do some refactoring in
the `TerminalOutput` class to make that accessible.
Other than that, the rest was fairly straightforward. It was just a
matter of packaging up all the information into the correct format for
the returned `DCS` string, and in the case of the restore operations,
parsing the incoming data and applying the new state.
## Validation Steps Performed
Thanks to @al20878, we were able to test these operations on a real
VT525, and I've manually verified that our implementation matches that
behavior. I've also added some unit tests covering both reports.
Closes#14984
When a `DECCRA` operation is copying content that spans a double width
line, it's possible that some range of the bounding rectangle will be
off-screen, and that range is not supposed to be copied. However, the
code checking for off-screen positions was using incorrect coordinates,
so we would mistakenly copy content that shouldn't be copied, and drop
content that should have been copied. This PR fixes that.

## Summary
_Thus we come to the introduction of a new servant, the
`ContentManager`, a singular entity that serves at the behest of the
`emperor`. It is its charge to keep track of all `TermControl` instances
created by the windows, for each window must seek its blessing before
calling forth such an instance._
_With the aid of the `ContentManager`, the `TermControl` shall now be
traced by the hand of fate through the use of unique identifying marks,
known as `GUID`s. Yet, its purpose remains yet unknown, for it is merely
a waypoint upon the journey yet to come._
_This act of bridging also brings a change to the handling of events
within the `TermControl`. This change shall see the addition of a
revoker, similar to the manner in which the `AppHost` hath employed it,
to the `TermControl`. Additionally, there is a new layer of indirection
between the `ControlCore` and the `App` layer, making ready for the day
when the `TermControl` may be repositioned and re-parented with ease._
_Consider this but a trivial act, a mere shadow of things yet to come,
for its impact shall be felt but briefly, like the passing of a gentle
breeze._

# Detailed description
This PR is another small bridge PR between the big work in #14843, and
the PR that will enable panes to move between windows.
This introduces a new class, called `ContentManager`. This is a global
singleton object, owned by the emperor. Whenever a window wants to
instantiate a new `TermControl`, it must ask the ContentManager to give
it one. This allows the ContentManager to track each "content" by GUID.
That's it. We don't do anything with them in this PR by itself, we just
track them.
This also includes a small change to the way TermControl events are
handled. It adds an `AppHost`-like revoker struct, and weak_ref's all
the handlers. We also add a layer of indirection between the
ControlCore's raising of events and the App layer's handling. This will
make reparenting content easier in the future.
This is a pretty trivial change which shouldn't have any major side
effects. Consider it exposition of the things to come. It's
intentionally small to try and keep the reviews more managable.
Due to a limitation in the Windows App Installer UI, Terminal had to
shell out to `reg.exe` to write the Delegation registry keys. The team
in charge of AppInstaller lifted that (once by-policy) limitation.
Therefore, we can remove our BODGY workaround.
It was brought to my attention that we should be more restrictive in
which tasks we ovver a GitHub token to. Sorry!
With thanks to sitiom for the version parsing and the magic GitHub
action syntax incantation for determining what is a prerelease.
## Summary
_In the days of old, the windows were sundered, each with its own
process, like the scattered stars in the sky. But a new age hath dawned,
for all windows now reside within a single process, like the bright gems
of a single crown._
_And lo, there came the `WindowEmperor`, a new lord to rule over the
global state, wielding the power of hotkeys and the beacon of the
notification icon. The `WindowManager` was cast aside, no longer needed
to seek out other processes or determine the `Monarch`._
_Should the `WindowEmperor` determine that a new window shall be raised,
it shall set forth a new thread, born from the ether, to govern this new
realm. On the main thread shall reside a message loop, charged with the
weighty task of preserving the global state, guarded by hotkeys and the
beacon of the notification icon._
_Each window doth live on its own thread, each guarded by the new
`WindowThread`, a knightly champion to hold the `TerminalWindow`,
`AppHost`, and `IslandWindow` in its grasp. And so the windows shall run
free, no longer burdened by their former ways._
All windows are now in a single process, rather than in one process per
window. We'll add a new `WindowEmperor` class to manage global state
such as hotkeys and the notification icon. The `WindowManager` has been
streamlined and no longer needs to connect to other processes or
determine a new `Monarch`. Each window will run on its own thread, using
the new `WindowThread` class to encapsulate the thread and manage the
`TerminalWindow`, `AppHost`, and `IslandWindow`.

## Windows Terminal Process Model 3.0
Everything is now one process. All the windows for a single Terminal
instance live in a singular Terminal process. When a new terminal
process launches, it will still attempt to communicate with an existing
one. If it finds one, it'll pass the commandline to that process and
exit. Otherwise, it'll become the "monarch" and create a new window.
We'll introduce a new abstraction here, called the `WindowEmperor`.
`Monarch` & `Peasant` will still remain, for facilitating cross-window
communication. The Emperor will allow us to have a single dedicated
class for all global state, and will now always represent the "monarch"
(rather than our previously established non-deterministic monarchy to
elevate a random peasant to the role of monarch). We still need to do a
very minimal amount of x-proc calls. Namely, one right on startup, to
see if another `Terminal.exe` was already running. If we find one, then
we toss our commandline at it and bail. If we don't, then we need to
`CoRegister` the Monarch still, to prepare for subsequent launches to
send commands to us.
`WindowManager` takes the most changes here. It had a ton of logic to
redundantly attempt to connect to other monarchs of other processes, or
elect a new one. It doesn't need to do any of that anymore, which is a
pretty dramatic change to that class.
This creates the opportunity to move some lifetime management around.
We've played silly games in the past trying to have individual windows
determine if they're the singular monarch for global state.
`IslandWindow`s no longer need to track things like global hotkeys or
the notification icon. The emperor can do that - there's only ever one
emperor. It can also own a singular copy of the settings model, and hand
out references to each other thread.
Each window lives on separate threads. We'll need to separately
initialize XAML islands for each thread. This is totally fine, and
actually supported these days. We'll use a new class called
`WindowThread` to encapsulate one of these threads. It'll be responsible
for owning the `TerminalWindow`, `AppHost` and `IslandWindow` for a
single thread.
This introduces new classes of bugs we'll need to worry about. It's now
easier than ever to have "wrong thread" bugs when interacting with any
XAML object from another thread. A good case in point - we used to stash
a `static` `Brush` in `Pane`, for the color of the borders. We can't do
that anymore! The first window will end up stashing a brush from its
thread. So now when a second window starts, the app explodes, because
the panes of that window try to draw their borders using a brush from
the wrong thread.
_Another fun change_: The keybinding labels of the command palette.
`TerminalPage` is the thing that ends up expanding iterable `Command`s.
It does this largely with copies - it makes a new `map`, a new `vector`,
copies the `Command`s over, and does the work there before setting up
the cmdpal.
Except, it's not making a copy of the `Command`s, it's making a copy of
the `vector`, with winrt objects all pointing at the `Command` objects
that are ultimately owned by `CascadiaSettings`.
This doesn't matter if there's only one `TerminalPage` - we'll only ever
do that once. However, now there are many Pages, on different threads.
That causes one `TerminalPage` to end up expanding the subcommands of a
`Command` while another `TerminalPage` is ALSO iterating on those
subcommands.
_Emperor message window_: The Emperor will have its own HWND, that's
entirely unrelated to any terminal window. This window is a
`HWND_MESSAGE` window, which specifically cannot be visible, but is
useful for getting messages. We'll use that to handle the notification
icon and global hotkeys. This alleviates the need for the IslandWindow
to raise events for the tray icon up to the AppHost to handle them. Less
plumbing=more good.
### Class ownership diagram
_pretend that I know UML for a second_:
```mermaid
classDiagram

class Monarch
class Peasant
class Emperor
class WindowThread
class AppHost
Monarch "1" --o "*" Peasant: Tracks
Emperor --* "1" AppLogic:
Monarch <..> "1" Emperor
Peasant "1" .. "1" WindowThread
Emperor "1" --o "*" WindowThread: Tracks
WindowThread --* AppHost
AppHost --* IslandWindow
AppHost --* TerminalWindow
TerminalWindow --* TerminalPage
```
* There's still only one `Monarch`. One for the Terminal process.
* There's still many `Peasant`s, one per window.
* The `Monarch` is no longer associated with a window. It's associated
with the `Emperor`, who maintains _all_ the Terminal windows (but is not
associated with any particular window)
* It may be relevant to note: As far as the `Remoting` dll is concerned,
it doesn't care if monarchs and peasants are associated with windows or
not. Prior to this PR, _yes_, the Monarch was in fact associated with a
specific window (which was also associated with a window). Now, the
monarch is associated with the Emperor, who isn't technically any of the
windows.
* The `Emperor` owns the `App` (and by extension, the single `AppLogic`
instance).
* Each Terminal window lives on its own thread, owed by a `WindowThread`
object.
* There's still one `AppHost`, one `IslandWindow`, one `TerminalWindow`
& `TerminalPage` per window.
* `AppLogic` hands out references to its settings to each
`TerminalWindow` as they're created.
### Isolated Mode
This was a bit of a tiny brainstorm Dustin and I discussed. This is a
new setting introduced as an escape watch from the "one process to rule
them all" model. Technically, the Terminal already did something like
this if it couldn't find a `Monarch`, though, we were never really sure
if that hit. This just adds a setting to manually enable this mode.
In isolated mode, we always instantiate a Monarch instance locally,
without attempting to use the `CoRegister`-ed one, and we _never_
register one. This prevents the Terminal from talking with other
windows.
* Global hotkeys won't work right
* Trying to run commandlines in other windows (`wt -w foo`) won't work
* Every window will be its own process again
* Tray icon behavior is left undefined for now.
* Tab tearout straight-up won't work.

Credit where credit is due - @jboelter did literally all the hard work.
I just separated this out to two elements:
* Are we running elevated?
* Can we drag drop?
As we learned in #7754, the builtin administrator _can_ drag drop. But
critically, they are also running as admin! The way we had this logic
before, we're treat them as unelevated, because we had been overloading
the meaning here.
This splits these into two separate functions. Comes with the added
benefit of re-adding the elevation shield to the Terminal window for
users with UAC disabled (which was missing before) (and can _still_ be
disabled).

#14745 contains two regressions related to console alias handling:
* When `ProcessAliases` expands the backup buffer into (an) aliased
command(s) it changes the `_bytesRead` field of `COOKED_READ_DATA`,

* Multiline aliases are read line-by-line whereas #14745 didn't treat
them any different from regular single-line inputs.

This PR adds support for querying the color indices set by the `DECAC`
control, using the existing `DECRQSS` implementation.
## References and Relevant Issues
The initial `DECRQSS` support was added in PR #11152.
The `DECAC` functionality was added in PR #13058, but at the time we
didn't know how to format the associated `DECRQSS` query.
## Detailed Description of the Pull Request / Additional comments
For most `DECRQSS` queries, the setting being requested is identified by
the final characters of its escape sequence. However, for the `DECAC`
settings, you also need to include a parameter value, to indicate which
color item you're querying.
This meant we needed to extend the `DECRQSS` parser, so I also took this
opportunity to ensure we correctly parsed any parameter prefix chars. We
don't yet support any setting requiring a prefix, but this makes sure we
don't respond incorrectly if an app does query such a setting.
## Validation Steps Performed
Thanks to @al20878, we've been able to test how these queries are parsed
on a real VT525 terminal, and I've manually verified our implementation
matches that behavior.
I've also extended the existing `DECRQSS` unit test to confirm that we
are responding to the `DECAC` queries as expected.
Closes#13091
Experimental for now. `experimental.rightClickContextMenu`, a

Closes#3337
This adds **two** context menus to the `TermControl` - one for
right-clicking with a selection, and one without. The implementation is
designed to follows the API experience of the context menu on something
like a [`RichEditBox`](winui2gallery://item/RichEditBox). The hosting
application adds a handler for the menu's `Opening` event, and appends
whatever items it wants at that time.
So `TermControl` only implements a few "actions" by default - copy,
past, find. `TerminalApp` is then responsible for adding anything else
it needs. Right now, those actions are:
* Duplicate tab
* Duplicate pane
* Close Tab
* Close pane

<details>
<summary>Or, as I wrote it originally. </summary>
This is the first of the commits in the long saga which will culminate
in tab tear-out for the Terminal.
This the most functionally trivial of the PRs. It mostly just splits up
code that's currently in TerminalPage & AppLogic, and moves it into a
new class `TerminalWindow`. In the future, these classes will separate
responsibility as such:
* There will be one `AppLogic` per process, shared across all Terminal
windows.
* There will be one `AppHost`, `TerminalWindow`, and `TerminalPage` for
each individual window in the process.
This PR prepares for that by moving some state that's applicable to
_individual windows_ into `TerminalWindow`. This is almost exclusively a
code moving PR. There should be minimal functional changes.

In the next PR, we'll introduce the actual "Process Model v3", merging
all Terminal windows into a single terminal process.

### Detailed description
> Q: Does `AppLogic` not keep track of its windows?
Sure doesn't! I didn't think that was something it needed to know.
>Q: Why does `TerminalWindow` (per-window) have access to the
commandline args (per-process)
It's because it's _not_ per process. Commandline args _are_ per-window.
Consider - you launch the Terminal, then run a `wt -w -1 -- foo`. That
makes its own window. In this process, yes. But that new window has its
own commandline args, separate from the ones that started the original
process.
The `Sample` method has an offset parameter which we can use here.
The result is not identical to the old shader, as the older shader
used the height of the terminal for drawing horizontal edges and so
the result looked way fatter than it was seemingly originally intended.
On my 150% scale display I found an offset of +/- 2px to produce an
acceptable result, although in the future it might be worthwhile to
make the offset dependent on the UI scale.
Closes#14953
## Summary of the Pull Request
This fixes a couple of audit failures in `TerminalCore` where the
compiler was complaining about functions that should have been declared
as `noexcept`.
These failures have actually existed for a while, but you'd only see
them if you ran the audit build locally. They only recently started
showing up on the CI build server - I'm guessing because the compiler
there has now been upgraded.
## Validation Steps Performed
Compiled the audit build locally and it no longer fails.
This PR implements the `DECRQCRA` escape sequence, which lets you
request a checksum of a portion of the screen. This is most useful in
automated testing to verify that the generated screen content is what it
was expected to be.
For now this functionality is gated behind a feature flag which is only
enabled for dev builds.
## Detailed Description of the Pull Request / Additional comments
I've done my best to match the DEC checksum algorithm as closely as
possible, which we've determined by testing on a real VT525 terminal
(many thanks to @al20878 for that).
The checksum is an unsigned 16-bit value that starts off at zero, and
from which you then subtract the ordinal value of every character in the
selected range. It's also affected by the rendition attributes in the
selected cells.
* Bold/Intense - subtract 0x80
* Blinking - subtract 0x40
* Reverse video - subtract 0x20
* Underlined - subtract 0x10
* Invisible - subtract 0x08
* Protected - subtract 0x04
* Background color - subtract the color index
* Foreground color - subtract the color index * 0x10
I should note that our ordinal calculation only matches DEC for the
characters in the ASCII and Latin-1 range, because the original
algorithm predates Unicode. If we want to support the other character
sets correctly we'll need custom mapping tables, but I didn't think that
was essential for now.
It's also worth mentioning that we don't handle "empty" cells correctly,
but that's not the fault of the checksum calculation - it's just that
our default fill character is a space rather than a `NUL`.
## Validation Steps Performed
I've manually compared our implementation against the tests results that
@al20878 got from the VT525, and confirmed that we match as well as was
expected (i.e. taking into account the limitations mentioned above).
I've also added a few basic unit tests that verify we're generating the
expected checksums for the various renditions and color attributes.

When a character is written in the last column of a row, the cursor
doesn't move, but instead sets a "delayed EOL wrap" flag. If another
character is then output while that flag is still set, the cursor moves
to the start of the next line, before writing to the buffer.
That flag is supposed to be reset when certain control sequences are
executed, but prior to now we haven't always handled that correctly.
With this PR, we should be resetting the flag appropriately in all the
places that it's expected to be reset.
For the most part, I'm following the DEC STD 070 reference, which lists
a bunch of operations that are intended to reset the delayed wrap flag:
`DECSTBM`, `DECSWL`, `DECDWL`, `DECDHL`, setting `DECCOLM` and `DECOM`,
resetting `DECCOLM`, `DECOM`, and `DECAWM`, `CUU`, `CUD`, `CUF`, `CUB`,
`CUP`, `HVP`, `BS`, `LF`, `VT`, `FF`, `CR`, `IND`, `RI`, `NEL`, `ECH`,
`DCH`, `ICH`, `EL`, `DECSEL`, `DL`, `IL`, `ED`, and `DECSED`.
We were already resetting the flag for any of the operations that
performed cursor movement, since that always triggers a reset for us.
However, I've now also added manual resets in those ops that weren't
moving the cursor.
Horizontal tabs are a special case, though. Technically the standard
says they should reset the flag, but most DEC terminals never followed
that rule, and most modern terminals agree that it's best for a tab to
leave the flag as it is. Our implementation now does that too.
But as mentioned above, we automatically reset the flag on any cursor
movement, so the tab operation had to be handled as a special case,
saving and restoring the flag when the cursor is updated.
Another flaw in our implementation was that we should have been saving
and restoring the flag as part of the cursor state in the `DECSC` and
`DECRC` operations. That's now been fixed in this PR too.
I should also mention there was a change I had to make to the conpty
renderer, because it was sometimes using an `EL` sequence while the
terminal was in the delayed EOL wrap state. This would reset the flag,
and break subsequent output, so I've now added a check to prevent that
from happening.
## Validation Steps Performed
I've added some unit tests that confirm the operations listed above are
now resetting the delayed EOL wrap as expected, and I've expanded the
existing `CursorSaveRestore` test to make sure the flag is being saved
and restored correctly.
I've also manually confirmed that the test case in issue #3177 now
matches XTerm's output, and I've confirmed that the results of the
wraptest script[^1] now match XTerm's results.

The overarching intention of this PR is to improve our Unicode support.
Most
of our APIs still don't support anything beyond UCS-2 and DBCS
sequences.
This commit doesn't fix the UTF-16 support (by supporting surrogate
pairs),
but it does improve support for UTF-8 by allowing longer `char`
sequences.
It does so by removing `TranslateUnicodeToOem` which seems to have had
an almost
viral effect on code quality wherever it was used. It made the
assumption that
_all_ narrow glyphs encode to 1 `char` and most wide glyphs to 2
`char`s.
It also didn't bother to check whether `WideCharToMultiByte` failed or
returned
a different amount of `char`s. So up until now it was easily possible to
read
uninitialized stack memory from conhost. Any code that used this
function was
forced to do the same "measurement" of narrow/wide glyphs, because _of
course_
it didn't had any way to indicate to the caller how much memory it needs
to
store the result. Instead all callers were forced to sorta replicate how
it
worked to calculate the required storage ahead of time.
Unsurprisingly, none of the callers used the same algorithm...
Without it the code is much leaner and easier to understand now. The
best
example is `COOKED_READ_DATA::_handlePostCharInputLoop` which used to
contain 3
blocks of _almost_ identical code, but with ever so subtle differences.
After
reading the old code for hours I still don't know if they were relevant
or not.
It used to be 200 lines of code lacking any documentation and it's now
50 lines
with descriptive function names. I hope this doesn't break anything, but
to
be honest I can't imagine anyone having relied on this mess in the first
place.
I needed some helpers to handle byte slices (`std::span<char>`), which
is why
a new `til/bytes.h` header was added. Initially I wrote a `buf_writer`
class
but felt like such a wrapper around a slice/span was annoying to use.
As such I've opted for freestanding functions which take slices as
mutable
references and "advance" them (offset the start) whenever they're read
from
or written to. I'm not particularly happy with the design but they do
the job.

Our templates were declared in the wrong order in JsonUtils, so all we
needed to do was reorder them. The tests bear this out.
This allows us to disable two-phase template name lookup. I also fixed a
minor issue that resulted in the inclusion of too many copies of
expandIconPath.
Interesting things we could do after this:
- remove all `InitializeComponent` calls - they do it automatically
- have some Clang support (!)
- use `std::optional`<->`IReference` automatic binding
- use `std::format` support (!) for json/uri/hostname/http stuff/all
`IStringable`s
- potentially move to `/await:strict` for C++20 coroutines
I've also fixed up a couple ambiguities introduced by this change.
* `lld-link` is more strict about the casing of keywords in `.def` files
* `[[nodiscard]]` must come before `virtual` and `static` qualifiers
* `precomp.h` is never to be included with `<>`
* We were calling the jsoncpp constructors directly (oops) as functions
(oops)
* ClipboardTests constructed `KeyEvent`s by copy instead of directly
* While we can `await` a `Dispatcher`, it's clearer to add `resume_foreground`
#13626 contains a small "regression" compared to #13321:
It now began to store trailers in the buffer wherever possible to allow
a region
of the buffer to be backed up and restored via Read/WriteConsoleOutput.
But we're unfortunately still ill-equipped to handle anything but UCS-2
via
WriteConsoleOutput, so it's best to again ignore trailers just like in
#13321.

* Removing all our local redefinitions of `NTSTATUS` in favor of that of `winternl.h`
* Because of this, we got to (had to?) remove some old transclusions from `conddkrefs.h`
* `NT_SUCCESS` (ours) -> `SUCCEEDED_NTSTATUS` (wil)
* `VERIFY_IS_TRUE(NT_SUCCESS())` (overly elaborate) -> `VERIFY_NT_SUCCESS` (WEX)
* `VERIFY_SUCCESS_NTSTATUS` (ours) -> `VERIFY_NT_SUCCESS` (WEX)

Does what it says in the title. After this commit you can customize the height
and width of the terminal's cells. This commit supports parts of CSS'
`<length-percentage>` data type: Font-size relative sizes as multiples (`1.2`),
percentage (`120%`), or advance-width relative (`1.2ch`), as well as absolute
sizes in CSS pixels (`px`) or points (`pt`).
This PR is neither bug free in DxEngine, nor in AtlasEngine.
The former fails to implement glyph advance corrections (for instance #9381),
as well as disallowing glyphs to overlap rows. The latter has the same
overlap issue, but more severely as it tries to shrink glyphs to fit in.

This pull request removes, in full, our dependency on cpprestsdk. This
allows us to shed 500KiB-1.2MiB from our package off the top and enables
the following future investments:
- Removal of the App CRT forwarders to save an additional ~500KiB
- Switching over to the HybridCRT and removing our dependency on _any
CRT_.
cpprest was built on my dev box two or so years ago, and is in _utter_
violation of our compliance guidelines on SBOM et al.
In addition, this change allows us to use the proxy server configured
in Windows Settings.
I did this in four steps (represented roughly by the individual commits):
1. Switch from cpprest's http_client/json to Windows.Web.Http and
Windows.Data.Json
2. Switch from websocketpp to winhttp.dll's WebSocket implementation¹
3. Remove all remaining utility classes
4. Purge all dependencies from all projects and scripts on cpprest.
I also took this opportunity to add a feature flag that allows Dev
builds to run AzureConnection in-process.
¹ Windows.Networking.Sockets' API is so unergonomic that it was simply
infeasible (and also _horrible_) to use it.
## Validation Steps
I've run the Azure Connection quite a bit inproc.
Closes#4575.
Might be related to #5977, #11714, and with the user agent thing maybe #14403.
This is a rather trivial changeset. Now that these two are present in the
`std` namespace there's no reason for us to continue using the `gsl` ones.
Additionally this ensures future compatibility with other 3rd party libraries.
When working on #14745 I noticed that `SplitToOem` was in a bit of a poor state
as well. Instead of simply iterating over its `deque` argument and writing the
results into a new `deque` it used `pop` to advance the head of both queues.
This isn't quite exception safe and rather bloaty. Additionally there's no need
to call `WideCharToMultiByte` twice on each character if we know that the most
verbose encoding is UTF-8 which can't be any more than 4 chars anyways.
Related to #8000.
## PR Checklist
* 2 unit tests cover this ✅
When working on #14745 I found `KeyEvent`s a little hard to read in the
debugger. I noticed that this is because of sign extension when converting
`char`s to `wchar_t`s in `KeyEvent::SetCharData`.
The original console output modes were considered attributes of the
buffer, while later additions were treated as global state, and yet both
were accessed via the same buffer-based API. This could result in the
reported modes being out of sync with the way the system was actually
behaving, and a call to `SetConsoleMode` without updating anything could
still trigger unpredictable changes in behavior.
This PR attempts to address that problem by making all modes part of the
buffer state, and giving them predictable default values.
While this won't solve all the tmux layout-breaking issues in #6987, it
does at least fix one case which was the result of an unexpected change
in the `DISABLE_NEWLINE_AUTO_RETURN` mode.
All access to the output modes is now done via the `OutputMode` field in
`SCREEN_INFORMATION`. The fields that were tracking global state in the
`Settings` class (`_fAutoReturnOnNewline` and `_fRenderGridWorldwide`)
have now been removed.
We still have a global `_dwVirtTermLevel` field, though, but that now
serves as a default value for the `ENABLE_VIRTUAL_TERMINAL_PROCESSING`
mode when creating a new buffer. It's enabled for conpty mode, and when
the VT level in the registry is not 0. That default doesn't change.
For the VT alternate buffer, things works slightly differently, since
there is an expectation that VT modes are global. So when creating an
alt buffer, we copy the current modes from the main buffer, and when
it's closed, we copy them back again.
## Validation Steps Performed
I've manually confirmed that this fixes the problem described in issue
#14690. I've also added a basic feature test that confirms the modes are
initialized as expected when creating new buffers, and changes to the
modes in one buffer do not impact any other buffers.
Closes#14690
New-TerminalStackedChangelog used to generate logs that looked like this:
```
* [3] A commit that was seen 3 times
* A commit that was only seen once
* [2] Some other commit
```
Now it will generate logs that look like this:
```

||/ base..branch-3
* [XXX] A commit that was seen 3 times
* [ X ] A commit that was only seen once
* [XX ] Some other commit
```
This format is more expressive, as it indicates _which branches_ contain which commits.
As a reminder, my release note writing style starts with a stacked changelog. It's how I tell (1) which commits are in the new preview release only, (2) which commits are in the new preview and the new stable release and (3) which commits were already released in a previous stable release.
Changes from 1 get included in the new changelog, changes from 2 get included in both and changes from 3 get deleted because they have already been released.
For some reason, Windows Terminal stops dispatching UIA TextChanged events sometimes. There isn't a reliable repro for this bug.
However, under NVDA's logger, it appears that when the bug does occur, we still dispatch UIA notifications (which may be ignored by NVDA in some configurations). A "quick fix" here is to dispatch a TextChanged event if we're going to dispatch a notification. Since we're just enabling a flag, we won't send two events at once.
Closes#10911
The `SignalTextChanged` crash seems to be occurring due to the `TermControlAutomationPeer` being destructed by the time the UIA event is actually dispatched. Even though we're already checking if TCAP and TermControl still exist, it could be that the TermControl is being closed as text is being output.
The proposed fix here is to record when the closing process starts and exposing that information directly to the TCAP. If TCAP sees that we're in the process of closing, don't bother sending a UIA event.
Closes#13978
Up until now, we have been relying on the catalog signature produced for our MSIX package.
There are some things (Packaged COM, Process Explorer as of 2022) that cannot handle catalog-signed
files. It's easier and safer for us to simply sign all the executables we produce before packaging them.
Unfortunately, we can't do it before we package them. We have to unpack and re-pack our package.
In the future, this will allow us to provide a codesigned distribution that is not in an MSIX package.
TEST=Ran a build and checked out the contents of the package. They were all signed!

We forgot to updateTheme again when we change the titlebar color. That would result in us setting the titlebar visibility only when the settings were reloaded, but if the unfocused BG was opaque, and the focused was transparent, we'd use the current _unfocused_ color to set the titlebar visibility.
Also, this fixes a bug with `tabRow.BG: terminalBackground`

This uses `shell:AppsFolder` to launch elevated instances of the app via
`ShellExecuteEx` and `runas` in elevate-shim.exe. The app to launch is
discovered via the `GetCurrentApplicationUserModelId` API.
e.g. `shell:AppsFolder\WindowsTerminalDev_8wekyb3d8bbwe!App`
This will fallback to launching `WindowsTerminal.exe` if it fails to
discover the app user model id to launch.
This also fixes a bug in elevate-shim where the first argument of
WinMain was lost (e.g. `new-tab`).
Curiously, `AppLogic::RunAsUwp()` is never called and
`AppLogic::IsUwp()` is always false when running debug builds locally
(e.g. WindowsTerminalDev). It's not clear if this is an artifact of
development packages or something else.
## Validation Steps Performed
Various manual debug/execution scenarios.
Verified the fallback path by running the unbundled app by extracting
the `CascadiaPackage_0.0.1.0_x64.msix` from the 'drop' build artifact.
Fixes#14501
This regressed when we implemented ColorSchemeViewModel in #13179.
This commit fixes that by automatically focusing the ColorSchemeListView
when we navigate to the ColorSchemes page, which makes sense from a
user experience perspective anyway.
Closes#11971
Specify the resource to use for the list view item background when selected.

## Validation Steps Performed
Background is no longer blue, it is light gray (like in Windows 11). Screenshots below.
This should make sure we only use Mica for the BG of the SUI when we're on a Windows build that supports it. Otherwise, we're just gonna get the emergency backstop / full transparency under it.
Confirmed this fixes it on my win10 VM.
Closes#14667
This PR add support for the ANSI Insert/Replace mode (`IRM`), which
determines whether output characters are inserted at the active cursor
position, moving existing content to the right, or whether they should
overwrite the content that is already there.
The implementation is a bit of a hack. When that mode is enabled, it
first measures how many cells the string is expected to occupy, then
scrolls the target line right by that amount before writing out the new
text.
In the longer term it might be better if this was implemented entirely
in the `TextBuffer` itself, so the scrolling could take place at the
same time as the content was being written.
## Validation Steps Performed
I've added a very basic unit test that verifies the mode is working as
expected. But I've also done a lot more manual testing, confirming edge
cases like wide characters, double-width lines, and both with and
without wrapping mode enabled.
Closes#1947
## Summary of the Pull Request
When we navigate to the color schemes page, find the default color scheme (if present) and manually set the container's automation name to include the word 'default'.
Note that we don't want to change the actual `ColorSchemeViewModel`'s name since that name is used internally to identify schemes. We only want to change the `ListViewItem`'s name, i.e. the container in the SUI.

Screen reader reads out the 'default' text now. It also correctly reads out the new default scheme if the default scheme is changed via SUI or json.
As of about 2022, the one's digit of the Build of our version is a placeholder value to differentiate the Windows 10 build from the Windows 11 build. Let's trim that out, it's only a source of confusion.
For additional clarity, let's omit the Revision, which _must_ be `.0`, and doesn't provide any value to report.
We will need to make sure we report releases as `1.17.ABC` now, instead of `1.17.ABC1.0`/`1.17.ABC2.0`
Let's not backport this. 1.17 will be the start of the new numbering scheme. Otherwise, `1.16.EFG` < `1.16.ABC1.0`, for an old version `ABC1` and a new version `EFG`.

## Validation Steps Performed
Settings UI still works (we _probably_ want to bug bash this at some
point though as with all SUI changes)
The main purpose of this PR was to merge the `ITerminalApi::PrintString`
implementations into a shared method in `AdaptDispatch`, and avoid the
VT code path depending on `WriteCharsLegacy`. But this refactoring has
also fixed some bugs that existed in the original implementations.
This helps to close the gap between the Conhost and Terminal (#13408).
I started by taking the `WriteCharsLegacy` implementation, and stripping
out everything that didn't apply to the VT code path. What was left was
a fairly simple loop with the following steps:
1. Check if _delayed wrap_ is set, and if so, move to the next line.
2. Write out as much of the string as will fit on the current line.
3. If we reach the end of the line, set the _delayed wrap_ flag again.
4. Repeat the loop until the entire string has been output.
But step 2 was a little more complicated than necessary because of its
legacy history. It was copying the string into a temporary buffer,
manually estimated how much of it would fit, and then passing on that
partial buffer to the `TextBuffer::Write` method.
In the new implementation, we just pass the entire string directly to
`TextBuffer::WriteLine`, and that handles the clipping itself. The
returned `OutputCellIterator` tells us how much of the string is left.
This approach fixes some issues with wide characters, and should also
cope better with future buffer enhancements.
Another improvement from the new implementation is that the Terminal now
handles delayed EOL wrap correctly. However, the downside of this is
that it introduced a cursor-dropping bug that previously only affected
conhost. I hadn't originally intended to fix that, but it became more of
an issue now.
The root cause was the fact that we called `cursor.StartDeferDrawing()`
before outputting the text, and this was something I had adopted in the
new implementation as well. But I've now removed that, and instead just
call `cursor.SetIsOn(false)`. This seems to avoid the cursor droppings,
and hopefully still has similar performance benefits.
The other thing worth mentioning is that I've eliminated some special
casing handling for the `ENABLE_VIRTUAL_TERMINAL_PROCESSING` mode and
the `WC_DELAY_EOL_WRAP` flag in the `WriteCharsLegacy` function. They
were only used for VT output, so aren't needed here anymore.
## Validation Steps Performed
I've just been testing manually, writing out sample text both in ASCII
and with wide Unicode chars. I've made sure it wraps correctly when
exceeding the available space, but doesn't wrap when stopped at the last
column, and with `DECAWM` disabled, it doesn't wrap at all.
I've also confirmed that the test case from issue #12739 is now working
correctly, and the cursor no longer disappears in Windows Terminal when
writing to the last column (i.e. the delayed EOL wrap is working).
Closes#780Closes#6162Closes#6555Closes#12440Closes#12739
I can't exactly repro #14559. I suspect that's due to #14567 having been merged. This, however, seemed related. Without this, we'll use the App's `RequestedTheme` (the one that can't be changed at runtime), rather than the user's `requestedTheme`. That will do weird things, like make the BG of the SUI dark, with white expanders.
I think this should close#14559.
Some investigation revealed that `_keyEvents` would get a `NULL_POINTER_READ` error. On the main thread, `RecordKeyEvent()` would be called, which mainly updates `_keyEvents`. On the renderer thread, `NotifyNewOutput()` would be called, which starts by iterating through `_keyEvents` and slowly clearing it out. On occasion, these two threads are modifying `_keyEvents` simultaneously, causing a crash.
The fix is to add a mutex on this variable.
Closes#14592
Basically what it says on the tin. For transparent tabs, we should layer on to the tab row to evaluate what the actual color of the tab will be. We did this for deselected tabs, but not for selected ones.

## Validation Steps Performed
Manually tested.
This builds upon #10749. When we added a separate pivot to track the "active" anchor, we forgot to update the pivot while circling. What does that mean? Moving the mouse would trigger us to update the selection using new endpoint and the old _pivot_, which hadn't been updated.
There's probably a more elegant way of doing this, but it's good enough.
Updated the test to cover this as well.

What it says on the tin.
I finally figured out the right way to validate schema updates in VsCode, which made this a lot faster. Tossed notes in the wiki for next time I do this.
Closes#14560
#14461 is caused by a null pointer exception in `TerminalIsSelectionActive()`. Since this reveals that it is possible to enter a state where `_terminal` is null, I've gone ahead and added null-checks throughout the code to make it more stable.
Closes#14461
## Validation Steps Performed
Ran locally. Still works.
CascadiaSettings relies on getting a JsonUtils::DeserializationException
from the various JSON Utility functions, and then formatting that into
an error message. Well, DeserializationException tries to include an
object representation in its what() message . . . and generates an
exception trying to do so. CascadiaSettings never gets the
DeserializationException, and displays a weird message.
It's safe to remove the stringification in DeserializationException
because CascadiaSettings was never using it (_and_ because
CascadiaSettings was using an even better version of the same logic.)
Fixes#14373
When the buffer contains wide characters that occupy more than one cell,
and those cells are scrolled horizontally by exactly one column, that
operation can result in the wide characters being completely erased.
This PR attempts to fix that bug, although it's not an ideal long term
solution.
Although not really to blame, it was PR #13626 that exposed this issue.
The root of the problem is that scrolling operations copy cells one by
one, but wide characters are written to the buffer two cells at a time.
So when you move a wide character one position to the left or right, it
can overwrite itself before it's finished copying, and the end result is
the whole character gets erased.
I've attempt to solve this by getting the affected operations to read
two cells in advance before they start writing, so there's no risk of
losing the source data before it's fully output. This may not work in
the long term, with characters wider than two cells, but it should at
least be good enough for now.
I've also changed the `TextBuffer::Write` call to a `WriteLine` call to
improve the handling of a wide character on the end of the line, where
moving it right by one column would place it half off screen. It should
just be dropped, but with the `Write` method, it would end up pushed
onto the following line.
## Validation Steps Performed
I've manually confirmed this fixes all the test cases described in
#14626, and also added some unit tests that replicate those scenarios.
Closes#14626
This is basically just like #14064, but with the `theme` instead.
If you define a pair of `theme` names:
```json
"theme": { "dark": "light", "light": "dark" },
```
then the Terminal will use the one relevant for the current OS theme. This cooperates with #14064, who sets the `scheme` based on the app's theme.
This was spec'd as a part of #3327 / #12530, but never promoted to its own issue.
Gif below.
In order to modify the accessibility information for the PseudoConsoleWindow, it needs to have a UIA provider registered. This PR introduces `PseudoConsoleWindowAccessibilityProvider` and registers it as a UIA provider appropriately. The registration process is based on that of the `WindowUiaProvider` for ConHost.
Closes#14385
## Validation Steps Performed
Run Accessibility Insights FastPass on the window. The PseudoConsoleWindow no longer is tagged as missing a name.
Depending on the line rendition, and whether the cursor is over a wide
character or not, it's possible for the width to take up anywhere from 1
to 4 cells. And when it's more than 1 cell wide, part of the cursor may
end up off screen. However, our bounds check requires the entire cursor
to be on screen, otherwise it doesn't render anything, and that can
result in cursor droppings being left behind. This PR fixes that.
The bounds check that is causing this issue was introduced in #13001 to
fix a debug assertion.
To fix this, I've removed the bounds checking, and instead clip the
cursor rect to the boundaries of the viewport. This is what the original
code was trying to do prior to the #13001 fix, but was mistakenly using
the `Viewport:Clamp` method, instead of `TrimToViewport`. Since this
implementation doesn't require a clamp, there should be no risk of the
debug assertion returning.
## Validation Steps Performed
I've confirmed that the test case in #14657 is now working correctly,
and not leaving cursor droppings behind. I've also tested under conhost
with buffer sizes wider than the viewport, and confirmed it can handle a
wide cursor partially scrolled off screen.
Closes#14657

## Detailed Description of the Pull Request / Additional comments
An optional parameter is added to TerminalPage::_CreateNewTabPane() and TerminalPage::_InitializeTab() which indicates the insert position of the duplicated tab.
During a new tab creation (not duplicate), this optional parameter has a default value(-1) and the new tab is inserted at the end.
The duplicated tab is inserted next to the original one even if it is not focused.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
Created different tabs and duplicated them.
Duplicated tabs that are focused and not focused.
This PR replaces the uses of `Viewport::CompareInBounds()` in the UIA code with `til::point` comparators. Additionally, it simplifies the logic further by using `std::max` and `std::min`.
In doing so, we are no longer hitting the `assert` in `CompareInBounds()`.
Closes#14542
2 new ConPTY APIs were added as part of this commit:
* `ClosePseudoConsoleTimeout`
Complements `ClosePseudoConsole`, allowing users to override the `INFINITE`
wait for OpenConsole to exit with any arbitrary timeout, including 0.
* `ConptyReleasePseudoConsole`
This releases the `\Reference` handle held by the `HPCON`. While it makes
launching further PTY clients via `PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE`
impossible, it does allow conhost/OpenConsole to exit naturally once all
console clients have disconnected. This makes it unnecessary to having to
monitor the exit of the spawned shell/application, just to then call
`ClosePseudoConsole`, while carefully continuing to read from the output
pipe. Instead users can now just read from the output pipe until it is
closed, knowing for sure that no more data will come or clients connect.
This is especially useful in combination with `ClosePseudoConsoleTimeout`
and a timeout of 0, to allow conhost/OpenConsole to exit asynchronously.
These new APIs are used to fix an array of bugs around Windows Terminal exiting
either too early or too late. They also make usage of the ConPTY API simpler in
most situations (when spawning a single application and waiting for it to exit).

## Summary of the Pull Request
Performs some cleanup in the Settings UI for the Launch Parameters settings:
1. Updates all `NumberBox` controls in the Settings UI to have a `Compact` `SpinButtonPlacementMode` instead of an inline one. This alleviates the XAML bug where the spin button would appear over the number box's input value.
2. Fixes an issue where a long X/Y value would resize the settings controls weirdly. This was fixed by introducing a `Grid` inside the main grid and applying a width to the number boxes.
3. Rename "Use system default" checkbox to be more clear. Propagate the new localized string into expander preview.

Similar to #14519.
Voice Access allows for functionality like "click <name>" to automatically move the cursor and click on a control. The Search Box had an AutoProp.Name that didn't match the button text, leading to confusion because Voice Access wouldn't be able to find a control named "Create".

Voice Access allows for functionality like "click \<name\>" to automatically move the cursor and click on a control. The Search Box had an AutoProp.Name that didn't match the placeholder text, leading to confusion because Voice Access wouldn't be able to find a control named "Find...".
To fix this, we simply aligned the placeholder text and the AutoProp.Name to be "Find". The elipses were removed because no dialog is opened.
The fix was accomplished in two ways to ensure that this is backportable:
1. via code, directly set the AutoProp.Name to match the placeholder text.
2. in the resources file, explicitly match the AutoProp.Name to the placeholder text. This allows this change to be backportable in the event that the code above wasn't backported.

The release of Windows Terminal has served as a way to reinvigorate the command-line ecosystem on Windows by providing a modern experience that is consistently updated. This experience has caused faster innovation in the Windows command-line ecosystem that can be seen across various areas like expanded virtual terminal sequence support and enhanced accessibility. Command-line apps can now leverage these innovations to create a better experience for the end-user.
Since accessibility is a very broad area, this document is intended to present recent innovations in the accessibility space for the command-line ecosystem. Furthermore, it will propose additional improvements that can be made alongside key stakeholders that could benefit from such changes.

We originally needed this library (or a separate DLL in our own project)
to handle hooking up the XAML resource loader to the providers that our
application needed. It was introduced in its nascent form in 2019, in a
PR titled "Make XAML files work."
It appears we no longer need it, and the provider hookup is being
handled by our `AppT2` base class override. I've tested this in Windows
10 Vb running unpackaged, and it seems to work totally fine. Crazy.
Removing this dependency saves us a couple hundred kilobytes on disk and
removes one consumer of the App CRT from our package.
Implements an initial version of #1571 as it has been specified, the
only big thing missing now is the possibility to add actions, which
depends on #6899.
Further upcoming spec tracked in #12584
Implemented according to [instructions by @zadjii-msft]. Mostly
relatively straightforward, but some notable details:
- In accordance with the spec, the counting/indexing of profiles is
based on their index in the json (so the index of the profile, not of
the entry in the menu).
- Resolving a profile name to an actual profile is done in a similar
fashion as how currently the `DefaultProfile` field is populated: the
`CascadiaSettings` constructor now has an extra `_resolve` function
that will iterate over all entries and resolve the names to instances;
this same function will compute all profile sets (the set of all
profiles from source "x", and the set of all remaining profiles)
- ~Fun~ fact: I spent two whole afternoons and evenings trying to add 2
classes (which turned out to be a trivial `.vcxproj` error), and then
managed to finish the entire rest of it in another afternoon and
evening...
## Validation Steps Performed
A lot of manual testing; as mentioned above I was not able to run any
tests so I could not add them for now. However, the logic is not too
tricky so it should be relatively safe.

This PR adds a new dynamic profile generator which creates profiles to
quickly connect to detected SSH hosts.
This PR adds a new `SshHostGenerator` inbox dynamic profile generator.
When run, it looks for an install of our
[Win32-OpenSSH](https://github.com/PowerShell/Win32-OpenSSH) client app
`ssh.exe` in all of the (official) places it gets installed. If the exe
is found, the generator then looks for and parses both the user and
system OpenSSH config files for valid SSH hosts. Each host is then
converted into a profiles to call `ssh.exe` and connect to those hosts.
VALIDATION
Installed OpenSSH, configured host for alt.org NetHack server, connected
and played some NetHack from the created profile.

We couldn't do this before, because `App::Current().Resources().Lookup()` would always return the OS theme version of a resource. That thread has lengthy details on why.
FORTUNATELY FOR US, this isn't the first time we've dealt with this. We've come up with a workaround in the past, and we can just use it again here.

## Summary of the Pull Request
This PR adds support for the DEC macro operations `DECDMAC` (Define Macro), and `DECINVM` (Invoke Macro), which allow an application to define a sequence of characters as a macro, and then later invoke that macro to execute the content as if it had just been received from the host.
This PR also adds two new `DSR` queries: one for reporting the available space remaining in the macro buffer (`DECMSR`), and another reporting a checksum of the macros that are currently defined (`DECCKSR`).

## Detailed Description of the Pull Request / Additional comments
I've created a separate `MacroBuffer` class to handle the parsing and storage of macros, so the `AdaptDispatch` class doesn't have to do much more than delegate the macro operations to that.
The one complication is the macro invocation, which requires injecting characters back into the state machine's input stream. Ideally we'd just pass the content to the `ProcessString` method, but we can't do that when it's already in the middle of a `CSI` dispatch.
My solution for this was to add an `OnCsiComplete` method via which we could register a callback function that injects the macro sequence only once the state machine has returned to the ground state. This feels a bit hacky, but that was the best approach I could come up with.
## Validation Steps Performed
Thanks to @KalleOlaviNiemitalo, we've been able to do some testing on a real VT420 to determine how the macro operations are intended to work, and I've tried to get our implementation to match that behavior as much as possible (we differ in some aspects of the checksum reporting, where the VT420 behavior seemed undesirable, or potentially buggy).
I've also added unit tests covering some of the same scenarios that we tested on the VT420.
This reverts commit 19b6d35.
This re-enables support for Mica, and transparent titlebars in general. It also syncs the titlebar opacity with the control opacity for `terminalBackground`. It also somehow fixes the bug where the bottom few pixels of the max btn doesn't work to trigger the snap flyout.
Closes#10509
Does nothing for #13631
### To-done's
* [x] Check the mica API on 22000, windows 11 RTM
- this works on 10.0.22621.674, but that's not 22000
* [x] Check how this behaves on windows 10.
- For both, this API just no-ops. That's fine! we can just say "Mica is only supported on >=22621"
This changeset includes various guards against resizing the terminal down to 0
columns/rows: The 2 `TextBuffer` locations that accept new sizes, as well as

## Detailed Description of the Pull Request / Additional comments
Added a null check before PInvoking TerminalSendOutput.
## Validation Steps Performed
Validated locally that the check prevents null strings from rendering.
When a terminal process exits (successful or not) and the profile isn't
set to automatically close the pane, a new message is displayed:
You can now close this terminal with ^D or Enter to restart.
Ctrl+D then is able to close the pane and Enter restarts it.
I originally tried to do this at the ConptyConnection layer by changing
the connection state from Failed to Closed, but then that didn't work
for the case where the process exited successfully but the profile isn't
set to exit automatically. So, I added an event to
ControlCore/TermControl that Pane watches. ControlCore watches to see if
the input is Ctrl+D (0x4) and if the connection is closed or failed, and
then raises the event so that Pane can close itself. As it turned out, I
think this is the better place to have the logic to watch for the Ctrl+D
key. Doing it at the ConptyConnection layer meant I had to parse out the
key from the escaped text passed to ConptyConnection::WriteInput.
## Validation Steps Performed
Tried adding lots of panes and then killing the processes outside of
Terminal. Each showed the new message and I could close them with Ctrl+D
or restart them with Enter. Also set a profile to never close
automatically to make sure Ctrl+D would work when a process exits
successfully.

## Summary of the Pull Request
This pull request solved the problem of users not being able to set color schemes specifically for dark or light mode. Now the code has been updated to accept a dark and light color scheme in the json. The old setting is still compatible. Keep in mind if you update your color scheme through the settings UI, it will set both dark and light to the color scheme selected. This is because the settings UI update for selecting both Dark and Light color schemes is not supported yet.
This also solves the problem of the UI not using the system OS theme. Now you can select system theme and your color scheme will be selected based on if the system theme is dark or light.

## Validation Steps Performed
Individual testing along with the test case added.
My goal is to make `IRenderData` "snapshottable", so that we
can render a frame of text without holding the console lock.
To facilitate this, this commit merges our 3 data interfaces
into one. It includes no actual changes apart from renames.
This commit is just a slight refactor of `ConsoleProcessList` which I've noticed
was in a poor shape. It replaces iterators with for-range loops, etc.
Additionally this fixes a bug in `SetConsoleWindowOwner`, where it used to
default to the newest client process instead of the oldest.
Finally, it changes the process container type from a doubly linked list
over to a simple array/vector, because using linked lists for heap allocated
elements felt quite a bit silly. To preserve the previous behavior of
`GetProcessList`, it simply iterates through the vector backwards.
## Validation Steps Performed
* All unit/feature tests pass ✅
* Launching a TUI application inside pwsh inside cmd
and exiting kills all 3 applications ✅
This changeset consists of two parts:
* Refactor `PtySignalInputThread` to move more code from `_InputThread`
into the various `_Do*` handlers. This allows us to precisely control
console locking behavior which is the cause of this bug.
* Add the 1-line fix to `_DoSetWindowParent` to unlock the console before
calling foreign functions (`SetWindowLongPtrW` in this case).
This fix is theoretical in nature, based on a memory dump from an affected user
and most likely fixes: https://developercommunity.visualstudio.com/t/10199439
## Validation Steps Performed
* ConPTY tests complete. ✅
My long-term plan is to replace the `CodepointWidth` enum with a simple integer
return value that indicates the amount of columns a codepoint is wide.
This is necessary so that we can return 0 for ZWJs (zero width joiners).
This initial commit represents a cleanup effort around `CodepointWidthDetector`.
Since less code runs faster, this change has the nice side-effect of running
roughly 5-10% faster across the board. It also drops the binary size by ~1.2kB.
## Validation Steps Performed
* `CodepointWidthDetectorTests` passes ✅
* U+26bf (``"`u{26bf}"`` inside pwsh) is a wide glyph
in OpenConsole and narrow one in Windows Terminal ✅
This is a partial fix for the Get-Credential issue. While investigating it, I found that the pseudoconsole window is not marked as being "owned" (in NTUSER) by the PID/TID of the console application that is "hosted" "in" it. Doing this does not (and cannot) fix `Get-Credential` failing in DefTerm scenarios.
ConsoleSetWindowOwner is one of the operations that can be done by a conhost to any window, and so the RemoteConsoleControl can call through to the Win32 ConsoleControl to pull it off.
I chose to add SetWindowOwner to the IConsoleControl interface instead of moving ConsoleControl::Control into the interface to reduce the amount of churn and better separate interface responsibilities.

As noted in #11000.
This adds support for `FTCS_COMMAND_START`, `FTCS_COMMAND_EXECUTED` and `FTCS_COMMAND_FINISHED`, which allow a shell to more clearly markup parts of the buffer.
As a trick, I'm also making the `experimental.autoMarkPrompts` setting act like a `FTCS_COMMAND_EXECUTED` if it comes after a `FTCS_COMMAND_START`. This lets the whole sequence work for cmd.exe (which wouldn't otherwise be possible).

This PR adds support for the `DECRQM` (Request Mode) escape sequence,
which allows applications to query the state of the various modes
supported by the terminal. It also adds support for the `DECNKM` mode,
which aliases the existing `DECKPAM` and `DECKPNM` operations, so they
can be queried with `DECRQM` too.
This is one solution for #10153 (saving and restoring the state of
bracketed paste mode), and should also help with #1040 (providing a way
for clients to determine the capabilities of the terminal).
Prior to adding `DECRQM`, I also did some refactoring of the mode
handling to get rid of the mode setting methods in the `ITermDispatch`
interface that had no need to be there. Most of them were essentially a
single line of code that could easily be executed directly from the
`_ModeParamsHelper` handler anyway.
As part of this refactoring I combined all the internal `AdaptDispatch`
modes into an `enumset` to allow for easier management, and made sure
all modes were correctly reset in the `HardReset` method (prior to this,
there were a number of modes that we weren't restoring when we should
have been).
And note that there are some differences in behavior between conhost and
Windows Terminal. In conhost, `DECRQM` will report bracketed paste mode
as unsupported, and in Terminal, both `DECCOLM` and `AllowDECCOLM` are
reported as unsupported. And `DECCOLM` is now explicitly ignored in
conpty mode, to avoid the conpty client and conhost getting out of sync.
## Validation Steps Performed
I've manually confirmed that all the supported modes are reported in the
`DECRQM` tests in Vttest, and I have my own test scripts which I've used
to confirm that `RIS` is now resetting the modes correctly.
I've also added a unit test in `AdapterTest` that iterates through the
modes, checking the responses from `DECRQM` for both the set and reset
states.
I should also mention that I had to do some refactoring of the existing
tests to compensate for methods that were removed from `ITermDispatch`,
particularly in `OutputEngineTest`. In many cases, though, these tests
weren't doing much more than testing the test framework.
I originally added these platforms to prevent the .NET components from
building when you built the entire solution, and to prevent them from
building in CI.
It turns out that managing an extra thousand project-platform-config
triples is an absolute pain, **and** that we should have been building
these things in CI the entire time. So.
This should make life _a lot_ easier.
As a bonus, this PR enables the WPF test harness to build for ARM64.
This fixes two issues with `experimental.useBackgroundImageForWindow` I discovered while looking at #14260
* It looks like the opacity of the whole-window BG image wouldn't hot reload if the path didn't.
* > set useBGForWindow:true, focus a pane with an image, then set it to useBGForWindow:false, and observe a pane with <100 opacity. You'll be able to see the BG image left behind!
These are pretty easy to miss, so I can see how it happened.
I don't think this _technically_ closes that thread, though. Ultimately, I think OP's settings were just wrong (and possible didn't hot-reload). There's another, trickier bit I'm discussing in that thread, that might deserve its own separate follow-up for discussion.
#14160 didn't fix#14132 entirely. There seems to be a race condition left
where (on my system) 9 out of 10 times everything works correctly,
but sometimes OpenConsole exits, while pwsh and bash keep running.
My leading theory is that the new code is exiting OpenConsole faster than the
old code. This prevents clients from calling console APIs, etc. causing them
to get stuck. The old code (and new code) calls `ExitProcess` when the ConPTY
pipes break and I think this is wrong: In conhost when you close the window we
only call `CloseConsoleProcessState` via the `WM_CLOSE` event and that's it.
Solution: Remove the call to `RundownAndExit` for ConPTY.
During testing I found that continuously printing text inside msys2 will cause
child processes to only exit slowly one by one every 5 seconds.
This happens because `CloseConsoleProcessState` calls `HandleCtrlEvent` without
holding the console lock. This creates a race condition where most of the time
the console IO thread is the one picking up the `CTRL_CLOSE_EVENT`. But that's
problematic because the `CTRL_CLOSE_EVENT` leads to a `ConsoleControl` call of
type `ConsoleEndTask` which calls back into conhost's IO thread and
so you got the IO thread waiting on itself to respond.
Solution: Don't race conditions.
## Validation Steps Performed
* `Enter-VsDevShell` and close the tab
Everything exits after 5s ✅
* Run msys2 bash from within pwsh and close the tab
Everything exits instantly ✅
* Run `cat bigfile.txt` and close the tab
Everything exits instantly ✅
* Patch `conhost.exe` with `sfpcopy`, as well as `KernelBase.dll`
with the recent changes to `winconpty`, then launch and exit
shells and applications via VS Code's terminal ✅
* On the main branch without this modification remove the call to
`TriggerTeardown` in `RundownAndExit` (this speeds up the shutdown).
Run (msys2's) `bash.exe --login` and hold enter and then press Ctrl+Shift+W
simultaneously. The tab should close and randomly OpenConsole should exit
early while pwsh/bash keep running. Then retry this with this branch and
observe how the child processes don't stick around forever anymore. ✅
Upgrades check-spelling to v0.0.21
The command to apply changes should now work on Windows (it requires
Perl, but I believe that's more or less present most of the time, and it
should walk you through the rest of the required tools).
There are a bunch of new features, the most important here are probably
being able to update the metadata from Windows. (If it doesn't work,
please @ me).
Also, candidate.patterns will automatically suggest patterns. You can
see them in patterns.txt, e.g.:
```
# Automatically suggested patterns
# hit-count: 3831 file-count: 582
# IServiceProvider
\bI(?=(?:[A-Z][a-z]{2,})+\b)
```
The metadata bits (the hit count/file count) don't have to be retained
(I hope they'll be useful in deciding whether/or not to add a pattern,
i.e. "how applicable is it?"), the comment hinting at what the pattern
does is probably worth retaining.
We've been using more or less this version for a while internally
(including talk-to-bot, and, I do have a pattern that could be used to
let people use that in forks, but, I'm going to skip that for now).
This weekend, I did some cleanup for `act` (to run check-spelling
locally), and some minor polish.
You can see the runs I made in
https://github.com/check-spelling/terminal/actions

Doc updated in response to some discussion in [#11326] and
[#7774]. In those PRs, it became clear that there needs to be a simple way of
collecting up a whole group of profiles automatically for sorting in these
menus. Although discussion centered on how hard it would be for extensions to
provide that customization themselves, the `match` statement was added as a way
to allow the user to easily filter those profiles themselves.
This was something we had originally considered as a "future consideration", but
ultimately deemed it to be out of scope for the initial spec review.

## Validation Steps Performed
Added a test.
This commit is a from-scratch rewrite of `ROW` with the primary goal to get
rid of the rather bodgy `UnicodeStorage` class and improve Unicode support.
Previously a 120x9001 terminal buffer would store a vector of 9001 `ROW`s
where each `ROW` stored exactly 120 `wchar_t`. Glyphs exceeding their
allocated space would be stored in the `UnicodeStorage` which was basically
a `hashmap<Coordinate, String>`. Iterating over the text in a `ROW` would
require us to check each glyph and fetch it from the map conditionally.
On newlines we'd have to invalidate all map entries that are now gone,
so for every invalidated `ROW` we'd iterate through all glyphs again and if
a single one was stored in `UnicodeStorage`, we'd then iterate through the
entire hashmap to remove all coordinates that were residing on that `ROW`.
All in all, this wasn't the most robust nor performant code.
The new implementation is simple (from a design perspective):
Store all text in a `ROW` in a regular string. Grow the string if needed.
The association between columns and text works by storing character offsets
in a column-wide array. This algorithm is <100 LOC and removes ~1000.
As an aside this PR does a few more things that go hand in hand:
* Remove most of `ROW` helper classes, which aren't needed anymore.
* Allocate backing memory in a single `VirtualAlloc` call.
* Rewrite `IsCursorDoubleWidth` to use `DbcsAttrAt` directly.
Improves overall performance by 10-20% and makes this implementation
faster than the previous NxM storage, despite the added complexity.

## Detailed Description of the Pull Request / Additional comments
All of these operations take a rectangle, defined by four coordinates.
These need to have defaults applied, potentially need to be clipped
and/or clamped within the active margins, and finally converted to
absolute buffer coordinates. To avoid having to repeat that boilerplate
code everywhere, I've pulled that functionality out into a shared method
which they all use.
With that out of the way, operations like `DECFRA` (fill), `DECERA`
(erase), and `DECSERA` (selective erase) are fairly simple. They're just
filling the given rectangle using the existing methods `_FillRect` and
`_SelectiveEraseRect`. `DECCRA` (copy) is a little more work, because we
didn't have existing code for that in `AdaptDispatch`, but it's mostly
just cloned from the conhost `_CopyRectangle` function.
The `DECCARA` (change attributes) and `DECRARA` (reverse attributes)
operations are different though. Their coordinates can be interpreted as
either a rectangle, or a stream of character positions (determined by
the `DECSACE` escape sequence), and they both deal with attribute
manipulation of the target area. So again I've pulled out that common
functionality into some shared methods.
They both also take a list of `SGR` options which define the attribute
changes that they need to apply to the target area. To parse that data,
I've had to refactor the `SGR` decoder from the `SetGraphicsRendition`
method so it could be used with a given `TextAttribute` instance instead
of just modifying the active attributes.
The way that works in `DECCARA`, we apply the `SGR` options to two
`TextAttribute` instances - one with all rendition bits on, and one with
all off - producing a pair of bit masks. Then by `AND`ing the target
attributes with the first bit mask, and `OR`ing them with the second, we
can efficiently achieve the same effect as if we'd applied each `SGR`
option to our target cells one by one.
In the case of `DECRARA`, we only need to create a single bit mask to
achieve the "reverse attribute" effect. That bit mask is applied to the
target cells with an `XOR` operation.
## Validation Steps Performed
Thanks to @KalleOlaviNiemitalo, we've been able to run a series of tests
on a real VT420, so we have a good idea of how these ops are intended to
work. Our implementation does a reasonably good job of matching that
behavior, but we don't yet support paging, so we don't have the `DECCRA`
ability to copy between pages, and we also don't have the concept of
"unoccupied" cells, so we can't support that aspect of the streaming
operations.
It's also worth mentioning that the VT420 doesn't have colors, so we
can't be sure exactly how they are meant to interpreted. However, based
on the way the other attribute are handled, and what we know from the
DEC STD 070 documentation, I think it's fair to assume that our handling
of colors is also reasonable.
Prior to this PR, the conhost vertical scrollbar would be forced to be
visible whenever the "Disable Scroll-Forward" option was set. It was
assumed that it would be needed as soon as the current viewport was
filled, so it was better to start off visible and disabled.
When the viewport height and buffer height are the same, though, the
scrollbar is never needed, and conhost compensates for that by making
the window narrower. But since we were still forcing the scrollbar to be
visible, that would result in it overlapping content in the rightmost
columns.
This PR attempts to fix that issue by simply leaving the scrollbar to
decide the visibility itself. This is perhaps not as aesthetically
pleasing when it starts off hidden and then later becomes visible, but
that seems better than having it overlap the content.
I've manually confirmed this fixes the problem reported in issue #2449.
Closes#2449
## Summary of the Pull Request
Compiler was raising the error: `expression did not evaluate to a constant.`, causing the solution to fail when building. Removing this `constexpr` fixes it.

Solution builds now
AuditMode was accidentally disabled in 1c6aa4d, around 2 years ago.
This should fix this issue and address all the warnings it now generates.
Related to #14129.
The following members were not initialized during construction:
* `CursorType _defaultCursorShape`
* `bool _suppressApplicationTitle`
* `bool _bracketedPasteMode`
* `size_t _hyperlinkPatternId`
* `SelectionExpansion _multiClickSelectionMode`
* `til::CoordType _scrollbackLines`
Unlike gcc and clang, MSVC is fairly tame when it comes to removing code
tainted by undefined behavior, so the most likely affect this had is that
we were reading uninitialized memory.
Related to #14129.
We already were setting the automation properties on the expander, however, we were not setting it on the content when an expander was present. This change applies the automation properties to both the expander and the child content (i.e. TextBox).
Closes#13827
There is a condition which causes the console host process (conhost.exe)
to crash with a `FAIL_FAST` in `WriteCharsLegacy`.
**_Repro Scenario:_** Two conditions need to be met for crash to happen:
1. The `ENABLE_PROCESSED_OUTPUT` console mode needs to be disabled. This
condition is met through the race condition, explained in the section
below.
2. We are printing a string where there is a full width character
(character that requires two spaces on the screen) being printed at
the edge of the console window. That is, we have one character space
available, and the character requires 2 spaces.
Running following script (attached to bug) causes a crash:
`for /l %%A in (0, 1, 10000) do start /B C:\test.bat`
The script `test.bat` repeatedly prints a console-width line
with a DBCS character that doesn't fit.
_**Race:**_ Normally, we get into `WriteCharsLegacy` with
`PROCESSED_OUTPUT` enabled. However, during the initialization of a new
CMD session, `cmd!ResetConsoleMode()` is called, which first sets the
output console mode to the value of `curOutputMode` (which is a static
variable initialized to 0) by calling `SetConsoleMode()`, before then
setting it to the desired output mode with processed output enabled:
```c++
void ResetConsoleMode( void )
{
static DWORD desOutMode = ENABLE_PROCESSED_OUTPUT | /* ... */;
SetConsoleMode(conOut, curOutputMode); // <------ sets console mode to 0, disabling processed output
if (GetConsoleMode(conOut, &curOutputMode)) {
if ((curOutputMode & desOutMode) != desOutMode) {
curOutputMode |= desOutMode;
if (!SetConsoleMode(conOut, curOutputMode) && /* ... */) // <----- enables processed output
```
If there is another instance of CMD that is producing output in between
these two `SetConsoleMode()` calls, then we may end up in
`WriteCharsLegacy` with processed output mode disabled.
This fix removes a `FAIL_FAST_IF` that checks for `PROCESSED_OUTPUT`
mode after the initial character processing loop.
Before RS5, this was an `ASSERT()`. This FAIL_FAST was added in RS5 in
PR !1794053 (which changed all `ASSERT`-likes to `FAIL_FAST_IF`.)
We believe this assertion guarded only the "processing" of Backspace,
Tab, CR and LF, and did not expect that we would get out of the
character processing loop with unprocessed glyph characters. The
`FAIL_FAST` is redundant in this case, as the handlers for the
Backspace, Tab, CR and LF characters we are already checking for
`PROCESSED_OUTPUT`. Therefore, it is safe to remove this `FAIL_FAST`.
It turns out that we *can* exit the loop with unprocessed glyph
characters. In these cases, we don't want to `FAIL_FAST`.

`TextBuffer` is buggy and allows a `Trailing` `DbcsAttribute` to be written
into the first column. Since other code then blindly assumes that there's a
preceding `Leading` character, we'll get called with a X coordinate of -1.
This issue will be fixed by #13626 and this commit fixes it in the meantime.
Additionally fixes an unimportant crash when the window height is 0px,
because it was annoying during testing and doesn't hurt to be fixed.

XAML has an issue in windows 10 where `Width="*"` does not work properly
inside the `DataTemplate` for a `ListView`. Because of this, the color
scheme list view items looked very strange in windows 10 (see #14187).
Thanks to that, we thought up a few new designs for the color schemes
page and selected a new one that blends the color chips with a region
that shows the foreground and background color with the text preview.

My hope with this commit is to make our code more robust against accidental
recursive locking, as well as making it easier to write code with confidence,
with only a slight performance trade-off.
## Validation Steps Performed

Silent MIDI notes can be used to seemingly deny a user's input for long
durations (multiple minutes). This commit improves the situation by ignoring
all DECPS sequences for a second when Ctrl+C/Ctrl+Break is pressed.
Additionally it fixes a regression introduced in 666c446:
When we close a tab we need to unblock/shutdown `MidiAudio` early,
so that `ConptyConnection::Close()` can run down as fast as possible.
## Validation Steps Performed

* Ctrl+C doesn't do anything ❎
* Closing the tab doesn't do anything ❎

If the opacity is set to 100%, the background becomes solid instead of 'fully opaque acrylic'. If the opacity is below 100% the acrylic material is re-enabled (depending on the user's settings).
## Validation Steps Performed
I updated two unit tests to reflect the change in behavior and manually tested the transition from <100% opacity to 100% opacity (and vice versa) on win11.
Steps:
1. Start with 100% opacity and acrylic material enabled.
2. Decrease opacity and observe acrylic effect.
3. Increase opacity back to 100% and disable the acrylic effect.
4. Decrease opacity and notice that acrylic effect is no longer there.

Lately I've been a bit concerned about issues resulting from b036cab enabling
`/fp:fast` throughout the entire project. This commit reverts that change and:
* Enables `/fp:contract` which defaults to off since VS 17.0
This re-enables FMA for floats on ARM64. Since this doesn't affect NANs, etc.
I don't expect any issues apart from a slight change in float accuracy.
* Introduces `TIL_FAST_MATH_BEGIN` with which `/fp:fast` can be selectively
enabled for code that benefits from it like `ColorFix.cpp`.
Without `TIL_FAST_MATH_BEGIN` `ColorFix` is about twice as slow
(which is actually very noticeable in real life).
This PR doesn't produce any noticeable performance regressions.

## Detailed Description of the Pull Request / Additional comments
This is just a temporary solution until we change our defterm handoff process. Because of the way the process currently works, we have no way of knowing that the connection has requested the window to be maximized until after we have already started a terminal session. This means that we have to manually maximize the window upon receiving the connection, instead of having the session _start_ maximized, as it probably should.
## Validation Steps Performed
`start /max python` with defterm enabled opens up python in a maximized WT window
The original implementation of the _Device Status Report_ sequence was
only capable of handling ANSI status queries. This PR adds the ability
to respond to private DEC queries as well.
To prove it's working as intended, I've also included support for the
DEC extended cursor position report (`DECXCPR`), which is essentially
the same as the ANSI cursor position report, but with an additional
parameter indicating the page number. Until we support paging, though,
that value is just hardcoded to 1.
## References
The method for distinguishing between ANSI options and the private DEC
options is based on the updates made to the `SM`/`RM` mode sequences in
PR #8469.
## Validation Steps Performed
I've added a couple of unit tests covering the `DECXCPR` report, and
also manually confirmed we now pass the _Extended Cursor-Position_ test
in vttest.

[Git2Git] Merged PR 8017580: Emit traces to determine user opt-in status for Default-by-default
We already have tracing in the console host that tells us when a
console session was successfully handed off to a Terminal. However, that
doesn't provide us enough information about Windows' intent in doing
so--namely, (1) whether the user _wanted_ that handoff to happen, OR (2)
whether the user has opted out because they didn't want it to happen.
(1) looks like any other hand-off, which will pollute our statistics
(2) doesn't generate any messages, because we fail out of handoff before
logging a single thing.

Fix a missing entry in the JSON schema for `intenseTextStyle`.
The JSON schema was missing an entry in the Profile section for
`intenseTextStyle`. I have added it as it appears in AppearanceConfig.
Note that this is currently duplicated in the schema -- however, this is
the pattern used already in Profile as AppearanceConfig entries have
alternate descriptions (and I have updated the description in that
section to make it clear it applies to unfocused terminals).
Longer-term, it likely makes sense to consolidate all entires into
ApperanceConfig and rely on the description for the `unfocusedApperance`
object/the name of the object to make the limited scope of those keys
clear, so that Profile can simply extend ApperanceConfig and the
duplication in the schema can be reduced.
## Validation Steps Performed

Partially addresses #13387
This pull request operates on the same theory as #14217, but at a lower
level. Carlos and I discovered that TerminalPage *already* has an
action-dispatching key preview handler, and that my implementation of
`IDirectKeyListener` handles focus-tree bubbling mostly correctly.
Because of that discovery, we learned we could move the
`IDirectKeyListener` into TerminalPage itself and not have to complicate
the SUI or the Command Palette with the DirectKey interface.

The way `DECARM` was initially implemented, we checked for repeated key
presses by matching the last recorded virtual key code, and used a 0 key
code to indicate that no key was pressed. This caused the VT query
responses to fail, because they generated key events with a 0 key code,
and that would end up being detected as a repeated key that should be
suppressed.
This PR fixes that issue by using a `std::optional` to track the last
key code, so if no key has been pressed we can represent that with
`std::nullopt`, and there's no way that can be confused with a genuine
key press.
The `DECARM` mode was introduced in PR #13981.
## Validation Steps Performed
I've manually tested in Vttest to confirm that the query reports are now
working again, even when `DECARM` is disabled. I've also checked that
`DECARM` itself it still working as expected.
Closes#14208
Problem:
* Calling `RundownAndExit` tries to flush out the last frame from `VtEngine`
* `VtEngine` indirectly calls `RundownAndExit` if the pipe is gone via `VtIo`
* `RundownAndExit` is called by other parts of OpenConsole
* `RundownAndExit` must be `[[noreturn]]` for most parts of OpenConsole
* `VtIo` itself has a mutex ensuring orderly shutdown
* In short, doing a thread safe orderly shutdown requires us to hold both,
a lock in `RundownAndExit` and `VtIo` at the same time, but while other parts
need a blocking `RundownAndExit`, `VtIo` needs a non-blocking one
* Refactoring the code to use optionally non-blocking `RundownAndExit`
requires refactoring and might prove to be just as buggy
Solution:
* Simply don't call `RundownAndExit` in `VtEngine` at all
* In case the write pipe breaks:
* `VtEngine` will close the handle
* The client should notice that their read pipe is broken and
close their write pipe sooner or later
* Once we notice that our read pipe is broken, we call `RundownAndExit`
* `RundownAndExit` might call back into `VtEngine` but
without a pipe it won't do anything
* In case the read pipe breaks or any other part calls `RundownAndExit`:
* We call `RundownAndExit`
* `RundownAndExit` might call back into `VtEngine` and depending on whether
the write pipe is broken or not it will simply write into it or ignore it

Instead of using the currently focused tab when an unfocused tab is duplicated, the `_MakePane(...)` function now uses an optional source tab argument that points to the correct tab being duplicated.
## Validation Steps Performed
Manually tested on multiple tabs with different profiles. Performed steps:

* Select `Duplicate Tab` option from the dropdown menu of the unfocused tab.
* Verify that the new tab has the same profile as the tab it was duplicated from.

The breadcrumbs in the SUI were not readable by screen readers because they are represented as a button with a text block inside of it. Turns out, if you make the DataTemplate's item `IStringable` (meaning it has a `ToString()`), it all magically works! Allowing the screen reader to read the button as text.
Closes#13826
This PR adds support for the `DECARM` (Auto Repeat Mode) sequence, which
controls whether a keypress automatically repeats if you keep it held
down for long enough.
Note that this won't fully work in Windows Terminal until issue #8440 is
resolved.
Every time we receive a `KeyDown` event, we record the virtual key code
to track that as the last key pressed. If we receive a `KeyUp` event the
matches that last key code, we reset that field. Then if the Auto Repeat
Mode is reset, and we receive a `KeyDown` event that matches the last
key code, we simply ignore it.
## Validation Steps Performed
I've manually tested the `DECARM` functionality in Vttest and confirmed
that it's working as expected. Although note that in Windows Terminal
this only applies to non-alphanumeric keys for now (e.g. Tab, BackSpace,
arrow keys, etc.)
I've also added a basic unit test that verifies that repeated key
presses are suppressed when the `DECARM` mode is disabled.
Closes#13919
It turns out that the negative margin for the progress ring is causing
the clipping in case the tab title gets too long:
43dbbd590f/src/cascadia/TerminalApp/TabHeaderControl.xaml (L18-L27)
The negative margin was introduced in #8113 because the progress ring is
supposed to replace the tab icon but the `TabView` still reserves space
even if no icon is set (see
https://github.com/microsoft/terminal/pull/8133#issuecomment-739098014).
However, it is not actually the `TabView` reserving space even when
there is no icon, but a workaround for a crash in the
`IconPathConverter` that returns a `BitmapIconSource` with a `nullptr`
source instead of a `nullptr` `IconSource`:
43dbbd590f/src/cascadia/TerminalSettingsModel/IconPathConverter.cpp (L143-L154)
The workaround in `IconPathConverter` could probably be removed as I did
not find any instance where it is still used in a way that could trigger
the mentioned crash, but I did not dare to just remove it as I do not
know enough about the code by far. Hence, I opted to just locally
instantiate the `IconSource` with a `nullptr` directly in `TerminalTab`.
Fixes#8910
This PR adds support for the selective erase escape sequences: `DECSED`,
`DECSEL`, and `DECSCA`. They provide a way of marking certain areas of
the screen as "protected", so you can erase the content everywhere else
without affecting those protected areas.
This adds another bit in the `CharacterAttributes` enum to track the
protected status of each cell, and an operation triggered by the
`DECSCA` sequence which can toggle that bit in the active attributes.
There there are two new erase operations triggered by the `DECSED` and
`DECSEL` sequences, which work similar to the existing `ED` (erase in
display) and `EL` (erase in line) operations, but which only apply to
unprotected cells.
I've also updated the `DECRQSS` settings request, so you can query the
active protected attribute status.
## Validation Steps Performed
I've manually confirmed that we pass the selective erase tests in Vttest
now, and I've also manually tested some more complicated edge cases and
confirmed that we match the behavior of the hardware VT240 emulator in
MAME.
For unit testing I've extended the existing erase tests to cover
selective erase as an additional option, I've added a test covering the
`DECSCA` sequence, and I've extended the `DECRQSS` adapter test to
confirm the attribute reporting is working.

Adds UIA events to the WPF control for the following items:
- selection changed
- text changed (and output)
- cursor changed
### Automation Peer
Similar to the architecture of the UWP TermControl, we added a
`HwndTerminalAutomationPeer` which acts as the
`TermControlAutomationPeer` in UWP. However, we don't need a XAML
wrapper here, so really we just need it to inherit from
`TermControlUiaProvider` (the `ITextProvider` implementation shared
across conhost and WT) and `IUiaEventDispatcher` (the event dispatching
interface that is responsible for signaling the screen reader that
something has changed).
### Removing the local echo
As with WT, we need to record key events to remove the local echo. These
recorded events are matched up with the output text. Each sequential
match is removed in the output text so that it's not read by the screen
reader.
### Detecting what to send events for
As with WT, a `UiaEngine` was added to the renderer and it is set up
when a UIA client is detected. WT would normally stop sending events
when focus was lost from the control. We do the same here.
### Automation properties
`TermControlUiaProvider` was upgraded to support property values. Such
properties include class name and control type. These align with those
set in `TermControlAutomationPeer`. Realistically, those should point to
these, but that requires a lot more work and a localization burden
(because we need to move the localized word "terminal").
`HwndTerminalAutomationPeer` takes this a step further and overrides the
class name to be `WPFTermControl`. This allows screen readers to provide
special handling for the `WPFTermControl` vs the UWP term control since
they will be updating at different speeds.
### Build fixes
To build the WPF test app, I had to mess with the dependencies a little
bit. Really just add the atlas engine and uia renderer to the build
steps.
### HwndTerminal initialization
The initialization order with `WM_NCCREATE` was changed to match that of
Windows Terminal (BaseWindow/IslandWindow). This is safer now. I also
removed the `static` window because it was unnecessary.
### Handling `WM_GETOBJECT`
WPF's HwndHost likes to mark the `WM_GETOBJECT` message as handled to
force the usage of the WPF automation peer. We now explicitly mark it as
not handled and don't return an automation peer. This forces the message
to go down to the HwndTerminal where we return terminal's UiaProvider.
### Remove TermControl layer from UIA tree
TermContol (the top-most layer in the UIA tree) would pop up and not do
anything. This PR also overrides the automation peer at that layer and
marks IsContentElement/IsControlElement=false (the equivalent to
AccessibilityView=Raw). This makes the layer only appear in the UIA tree
if you are using the raw view (i.e. you know what you're doing and you
want to see each individual layer even if you can't directly interact
with it).
## Validation Steps Performed
Tested with Narrator/NVDA using WpfTerminalTestNetCore project in our
repo.
- [X] New output is read out (not just key events, but also other output
text)
- [X] Local echo does not occur (i.e. pressing 'A' should only read 'A'
once, not twice [key event and rendered letter]).
- [X] selection events are read out properly
- [X] cursor change events are read out properly (tested with text
cursor indicator preview in Settings App > Accessibility > Text
Cursor)
NOTE: test this with Release builds. Debug builds may be too slow and
not read out properly

## Summary of the Pull Request
Update Nuget used
This change fixes issues with certain fonts that draw _way_ outside the advance
width/height black box and expect to remain centered on the baseline.
## Validation Steps Performed
* Use MesloLGM Nerd Font
* Print U+E0B0
* Ensure it's centered, even if it's cut off ✅
if the bot adds it, then the issue will get added to the project before the bot gets a chance to add the triage label. Just start with the triage label.
This commit changes the glyph scale algorithm to prefer aligning glyphs to
their baseline. This improves the visual appearance of simulated italic glyphs.
However wide Emojis in narrow cells now look slightly worse without centering.
Closes#13987
## Validation Steps Performed
* Use FiraCode which has no italic variant and instead uses simulated italics
* Write italic text
* Baseline is consistent ✅
`ConptyClosePseudoConsole` blocks until OpenConsole exits.
This is problematic for the changes in 666c446, which stopped calling that
function on a background thread to solve a race condition. This commit fixes
the potential lags/deadlocks from waiting on OpenConsole's exit, by adding
`ConptyClosePseudoConsoleNoWait` which only closes the IO handles and allows
OpenConsole to exit naturally. This uncovered another potential deadlock
in `ServiceLocator::RundownAndExit` which might call itself recursively.
Closes#14032
## Validation Steps Performed
* Print tons of text and concurrently close the tab.
Tab closes, OpenConsole/pwsh exits instantly ✅
* Use `Enter-VsDevShell` and close the tab.
Tab closes instantly, OpenConsole/pwsh exits after ~5 seconds ✅
When we first introduced the shell extension, it didn't work properly
for some folders (such as the Desktop, or perhaps any "background"
click) due to a bug in Windows. We worked around that bug with the help
of an awesome community member, who contributed code that would pull up
the topmost Explorer window and query its location.
That Windows bug was eventually fixed, but we still had trouble with
items appearing correctly. On Windows 11, the Open in Terminal menu item
appears and disappears at random when you right-click the desktop, but
it always appears when you right-click a folder. It sometimes appears
for Quick Access, even though it shouldn't.
We tried to fix that in #13206, but the fix caused more issues than it
solved. We reverted it for 1.15 and 1.16.
At the end of the day, it turns out that getting the path from the
toplevel explorer window is fragile. Fortunately, the shell does offer
us a way to get that information: the site chain.
This pull request replaces GetPathFromExplorer() with an implementation
of `IObjectWithSite`, which allows us to use the site chain to look up
from whence a context menu request was initiated. It also makes item
lookup generally more robust.

This PR attempts to simplify the `TextAttribute` class by merging the
two fields that were previously storing the "legacy" attributes and the
"extended" attributes separately.
When the `TextAttribute` class is initialized with a legacy value, we
were masking off the `META_ATTRS` bits to store in the `_wAttrLegacy`
field, and then additionally clearing the `COMMON_LVB_SBCSDBCS` bits,
so there were only 5 bits that were actually used in the end. We also
had an additional `_extendedAttrs` field holding other VT attributes,
which only used 8 of its available 16 bits.
In this PR I've now merged the the two sets of attributes into one enum,
so they all fit in a single 16-bit value. The legacy attributes retain
the same bit positions they originally had, so we can mask them off from
an incoming legacy value as we did before. I've just simplified the
process somewhat by creating a `USED_META_ATTRS` mask that covers the
exact subset of meta attributes that we care about.
The new enum that holds the combined attributes has now been named
`CharacterAttributes` rather than `ExtendedAttributes`, since that seems
to be the term typically used in VT documentation. This covers both
rendition/visual attributes and logical attributes (not yet used, but we
will need them at some point to support selective erase operations).
While making these changes I also noticed the `IsLeadingByte` and
`IsTrailingByte` methods weren't actually used anywhere, and weren't
correctly implemented anyway, so I've removed those now.
## Validation Steps Performed
I've manually run a number of attribute test scripts which cover both
legacy and VT operations, and everything still appears to be working
correctly.
Closes#14031
After this commit a user may specify fractional font sizes.
Support was only implemented for AtlasEngine however.
DxEngine continues to use rounded (integer) font sizes.
Closes#6678
## Validation Steps Performed
* Install a bitmap font that requires fractional font sizes
(e.g. Terminus TTF, https://files.ax86.net/terminus-ttf/)
* Set font size to something integer (e.g. 14pt)
Glyphs are blurry ✅
* Set font size to something fractional (e.g. 13.5pt)
Glyphs are crisp ✅
This commit fixes several issues:
* Some fonts set a line-gap even though they behave as if they
don't want any line-gaps. Since Terminals don't really have
any gaps anyways, it'll now not be taken into account anymore.
* Center alignment breaks bitmap glyphs which expect left-alignment.
* Automatic "opsz" axis makes Terminus TTF's italic glyphs look quite
weird. I disabled this feature as we might not need it anyways.
A complete fix depends on #14013Closes#14006
## Validation Steps Performed
* Use Terminus TTF at 13.5pt
* Print UTF-8-demo.txt
* No gaps between block characters ✅
If a rendering engine constantly throws error we'll effectively
denial-of-service our users by drowning them in warning popups.
This commit fixes the issue by limiting the retries in all cases.
Issue found in: #13985

* Launch Windows Terminal
* Only one warning popup shows up ✅
* Rendering is disabled until one clicks "resume" ✅
The `TileHashMap` refresh via `makeNewest()` in `StartPaint()` depends
on us filling the entire `cellGlyphMapping` row with valid data.

Disables strictness and warnings as errors for custom pixel shaders in
RELEASE. Windows terminal is not telling the user why the shader won't
compile which makes it very frustrating for the shader hacker.
After trying the recent preview none of my shaders loaded anymore in
Windows Terminal Preview which made me very sad. I had no idea what was
wrong with them. After cloning the git repo, building it, fighting an
issue that prevent DEBUG SDK from being used I finally was able to
identify some issues that were blocking my shaders.
> error X3556: integer modulus may be much slower, try using uints if possible.
> error X4000: use of potentially uninitialized variable (rayCylinder)
While the first one is a good warning I don't think it is an error and
the tools I use didn't flag it so was hard to know.
The second one I was staring at the code and was unable to identify what
exactly was causing the issues, I fumbled with the code a few times and
just felt the fun drain away.
IMHO: I want it to be fun to develop shaders for windows terminal.
Fighting invisible errors are not fun. I am not after building
production shaders for Windows Terminal, I want some cool effects. So
while I am as a .NET developer always runs with Warning as errors I
don't think it's the right option here. Especially since Windows
Terminal doesn't tell what is the problem.
However, I understand if the shaders you ship with Windows Terminal
should be free of errors and silly mistakes, so I kept the stricter
setting in DEBUG mode.
## Validation Steps Performed
Loaded Windows Terminal in RELEASE and DEBUG mode and validated that
RELEASE mode had reduced strictness but DEBUG retained the previous more
restrictive mode.

Hey maybe we should use more actions. This was thrown out during the last GH sync. Hopefully this doesn't explode.
This _should_ add all issues that don't have one of `Issue-Feature`, `Needs-Triage`, `Needs-Author-Feedback`, `Issue-Scenario` to the project board. That should just leave all the bugs and tasks that have been triaged.
I didn't go for
```yml
labeled: Issue-Task, Issue-Bug
label-operator: OR
```
since those would include untriaged ones.
There's also no way to filter on milestone currently, so this will likely add icebox issues. We'll need to remove those manually as needed.

This PR introduces a mechanism for passing through downloadable soft
fonts to the conpty client, so that we can support DRCS (Dynamically
Redefinable Character Sets) in Windows Terminal.
Soft fonts were first implemented in conhost (with the GDI renderer) in
PR #10011, and were implemented in the DX renderer in PR #13362.
The way this works is by passing through the `DECDLD` sequence
containing the font definition, but with the character set ID patched to
use a hardcoded value (this is to make sure it's not going to override
the default character set). At the same time we send through an `SCS`
sequence to map this character set into the G1 table so we can easily
activate it.
We still need to process the `DECDLD` sequence locally, though, since
the initial character set mapping take place on the host side. This gets
the DRCS characters into our buffer as PUA Unicode characters. Then when
the VT engine needs to output these characters, it masks them with `7F`
to map them back to ASCII, and outputs an `SO` control to activate the
soft font in the conpty client.
## Validation Steps Performed
I've manually tested with a number of soft fonts and applications that
make use of soft fonts. But if you're testing with the VT320 fonts from
the vt100.net collection, note that you'll need to enable the ISO-2022
coding system first, since they use 8-bit C1 controls.
When we added support for the `DECAC1` control sequence, which
determines whether `C1` controls are accepted or not, the intention was
that conhost would be making that determination, and Windows Terminal
would always be expected to accept any passed-through `C1` controls.
However, this didn't take into account that a passed-through `RIS`
sequence could end up disabling `DECAC1`, and that would leave Windows
Terminal incapable of processing any `C1` controls. This PR attempts to
fix that oversight.
The `DECAC1` sequence was added in PR #11690, when we disabled `C1`
acceptance by default.
This is a bit of a hack, but I've added a new `AlwaysAcceptC1` mode to
the state machine, which is enabled at startup in the Terminal, and is
never disabled. The parser then just needs to check whether either
`AcceptC1` or `AlwaysAcceptC1` are set.
## Validation Steps Performed
I've manually confirmed the test case in #13968 now works as expected.
Closes#13968
This PR introduces a mechanism for passing through line rendition
attributes to the conpty client, so we can support double-width and
double-height text in Windows Terminal.
Line renditions were first implemented in conhost (with the GDI
renderer) in PR #8664, and were implemented in the DX renderer in PR
#13102.
By default this won't add any additional overhead to the conpty output,
but as soon as there is any usage of double-size text, we switch to a
mode in which every line output will be prefixed with a line rendition
sequence. This is to ensure that the line attributes in the client
terminal are always in sync with the host.
Since this does add some overhead to the conpty output, we'd prefer not
to remain in this mode longer than necessary. So whenever there is a
full repaint of the entire viewport, we check to see if all of the lines
are single-width. If that is the case, we can then safely skip the line
rendition sequences in future updates.
One other small optimization is when the conpty update is only writing
out a single character (this is something we already check for). When
that is the case, we can safely skip the line rendition prefix, because
a single character update should never include a change of the line
rendition.
## Validation Steps Performed
I've manually tested that Windows Terminal now passes the double-size
tests in _Vttest_, and also confirmed various edge cases are working
correctly in my own double-size tests.

Our Windows branch name changed, and I took this opportunity to resolve
an issue where vpack builds would occasionally fail due to GitHub rate
limiting the Azure DevOps IP addresses.
`ATLAS_POD_OPS` doesn't check for `has_unique_object_representations` and so a
bug exists where `CachedCursorOptions` comparisons invoke undefined behavior.
The color of inactive tab text is incorrect since #13689 due to the introduction
of `til::color::layer_over` which incorrectly calculated the RGB values.

With AtlasEngine being enabled by default in 1.16 Preview it would look weird
if the `useAtlasEngine` option would still be called "experimental".
Additionally we're interested in how many users opt out of useAtlasEngine,

This is because while adding/removing/calling event handlers might be

This PR adds support for the `DECBKM` sequence, which provides a way for
applications to specify whether the `Backspace` key should generate a
`BS` character or a `DEL` character.
On the original VT100 terminals, the `Backarrow` key generated a `BS`,
and there was a separate `Delete` key that generated `DEL`. However, on
the VT220 and later, there was only the `Backarrow` key. By default it
generated `DEL`, but from the VT320 onwards there was an option to make
it generate `BS`, and the `DECBKM` sequence provided a way to control
that behavior programmatically.
On modern terminals, the `Backspace` key serves as the equivalent of the
VT `Backarrow`, and typically generates `DEL`, while `Ctrl`+`Backspace`
generates `BS`. When `DECBKM` is enabled (for those that support it),
that behavior is reversed, i.e. `Backspace` generates `BS` and
`Ctrl`+`Backspace` generates `DEL`.
This PR also gets the other `Backspace` modifiers more closely aligned
with the expected behavior for modern terminals. The `Shift` modifier
typically has no effect, and the `Alt` modifier typically prefixes the
generated sequence with an `ESC` character.
While not strictly related to `DECBKM`, I noticed while testing that the
`_SetInputMode` method was doing unnecessary work that was specific to
the `FocusEvent` mode. I've now moved that additional processing into
the `EnableFocusEventMode` method, which I think makes things somewhat
simpler.
## Validation Steps Performed
I've tested the basic `DECBKM` functionality in Vttest, and I've
manually tested all the modifier key combinations to make sure they
match what most modern terminals generate.
I've also added a unit test that confirms that the expected sequences
are generated correctly when the `DECBKM` mode is toggled.
Closes#13884

This reverts commit f785168aac (PR #13244)
The error logged to NVDA was caused by the following line of code in `_getTextValue()`:
`THROW_HR_IF(E_FAIL, !bufferSize.IsInBounds(_start) || !bufferSize.IsInBounds(_end));`
NVDA would expand a text range to encompass the document in the alt buffer. This means that the "end" would be set to the dangling "endExclusive" point (x = left, y = one past the end of the buffer). This is a valid range!
However, upon extracting the text, we would hit the code above. The exclusive end doesn't actually point to anything in the buffer, so we would falsly throw `E_FAIL`.
Though this could be fixed by adding a special check for the `endExclusive` in the line above, I suspect there are other places throughout the UIA code that hit this problem too. The safest course of action is to revert this commit entirely since it was a code health commit (it doesn't actually close an issue).
Closes#13866
This is conjecture - I was totally unable to repro the original crash here.
Based on the stacks in MSFT:39994969, it looks like we try to fire off a
`RaiseAutomationEvent`, which calls through UIA core, eventually to the point of
calling `ComPtr<WUX::Automation::Peers::IAutomationPeer>::{dtor}`. I'm guessing
based on the stacks that the TermControl has already been released and cleaned
up. However, the lambda in the `RunAsync` calls here only takes a ref to the
TCAP. The TCAP has an outstanding reference (maybe on the other side of the UIA
fence), and gets successfully resolved as strong, but when calling to
`RaiseAutomationEvent`, the `owner` we passed in is gonezo.
This explicitly passes a `weak_ref` to `TermControlAutomationPeer`, rather than
a raw ptr, so we can actually check if the control is still alive before _we_
dereference it. If it is, great, we've got a strong ref to it now and it won't
get torn down.
Again, this is hearsay. Without a repro, the only way we can confirm this is
gone is by just hoping the crashes go away. 🤞

## Summary of the Pull Request
Fix a bug where if you pressed the "Save" button, WT would crash. This was caused by adding the possibility that no color scheme is selected in the main page. With no "current scheme", attempting to get its "name" would cause a null ptr exception.
The fix is simple: just check if we actually have a current scheme.
Bonus points: if we don't have a current scheme, don't bother looking throught the color schemes for a match because we'll never find one.

#13269 - Color Schemes Rejuv
This pull request reintroduces aliases for `VkKeyScanW`,
`MapVirtualKeyW` and `GetKeyState` that redirect through ConIoSrv on
OneCore devices.
We made an assertion in PR !7096375 that those APIs were hosted in an
extension APIset that was present on all OneCore devices. It turned out
that this was _incorrect_: that APIset extension is only hosted on
OneCoreUAP and above.
This would not be a problem save for NanoServer. NanoServer is built on
top of OneCore.
As Nano is a container host OS, it is primarily interfaced vith via
ConPTY... which exercises the VkKeyScanW/MapVirtualKeyW codepaths quite
a bit. Those APIs started returning invalid data, which caused us to
convert all incoming keyboard events into numpad events. This didn't
prove to be an issue for CMD or PowerShell (weirdly,) but it did prove
to be an issue for Redis. Unfortunately, Redis is exactly the sort of
thing you might want to run in a container.
Reintroducing these aliases was complicated because we took the
opportunity to remove all of IInputServices (!7105348), which was a
wrapper around some code that would choose Win32 or OneCore depending on
the runtime environment.
I made the choice (with the help of Leonard Hecker) to reimplement these
functions in a different way: always call the delay-loaded version, and
then on OneCore editions check the return value and error code to ssee
if we hit a delay load failure. It incurs a minor cost, but all of the
delay loads are in-proc and do not require us to make a syscall, so that
cost is negligible.
Part of this new implementation requires us to change _all conhost
internal callers_ to use "OneCoreSafe" versions of those APIs. We can't
redirect the user32 versions out of the way and usurp their import
symbols, so this commit also introduces some warning defines. If you use
VkKeyScanW (and friends), you _should_ get a linker error. Assuming
HostAndPropsheetIncludes has been included. It very well may not have
been included.

The Windows 11 build is going to have the same package name, so it *must* have a different version.
The easiest way for us to do this is to add 1 to the revision field.
In short, for a given Terminal build 1.11, we will emit two different versions (assume this is build
4 on day 23 of the year):
- 1.11.234.0 for Windows 10
- 1.11.235.0 for Windows 11
This presents a potential for conflicts if we want to ship two builds produced back to back on the
same day... which is terribly unlikely.

It's also costly in terms of time, effort, and testing for us to validate a modification to a released OS. We have a mindbogglingly massive amount of automated machinery dedicated to processing and validating the things that we check in while developing the current OS builds. But it's a special costly ask to spin up some to all of those activities to validate backported fixes. We do it all the time for Patch Tuesday, but in those patches, they only pass through the minimum number of fixes required to maximize the restoration of productivity/security/revenue/etc. because every additional fix adds additional complexity and additional risk.
So from our little team working hard to make developers happy, we virtually never make the cut for servicing. We're sorry, but we hope you can understand. It's just the reality of the situation to say "nope" when people ask for a backport. In our team's ideal world, you would all be running the latest console bits everywhere everytime we make a change. But that's just not how it is today.

Accessibility applications are the most likely to resort to a method of spelunking the process tree or window handles to attempt to find content to read out. Presuming they have hardcoded rules for console-type applications, these algorithms could be surprised by the substitution of another terminal environment.
Accessibility applications are the most likely to resort to a method of spelunking the process tree or window handles to attempt to find content to read out. Presuming they have hard-coded rules for console-type applications, these algorithms could be surprised by the substitution of another terminal environment.
The major players here that I am considering are NVDA, JAWS, and Narrator. As far as I am aware, all of these applications attempt to drive their interactivity through UI Automation where possible. And we have worked with all of these applications in the past in improving their support for both `conhost.exe` and the Windows Terminal product. I have relatively high confidence that we will be able to work with them again to help update these assistive products to understand the new UI delegation, if necessary.
@@ -76,7 +76,7 @@ These are in accordance with ConHost's keyboard selection model.
This idea was abandoned due to several reasons:
1. Keyboard selection should be a standard way to interact with a terminal across all consumers (i.e. WPF control, etc.)
2. There isn't really another set of key bindings that makes sense for this. We already hardcoded <kbd>ESC</kbd> as a way to clear the selection. This is just an extension of that.
2. There isn't really another set of key bindings that makes sense for this. We already hard-coded <kbd>ESC</kbd> as a way to clear the selection. This is just an extension of that.
3. Adding 12 conditionally effective key bindings takes the spot of 12 potential non-conditional key bindings. It would be nice if a different key binding could be set when the selection is not active, but that makes the settings design much more complicated.
4. 12 new items in the command palette is also pretty excessive.
5. If proven wrong when this is in WT Preview, we can revisit this and make them customizable then. It's better to add the ability to customize it later than take it away.
Since we are planning on officially supporting unpackaged execution, I propose a special mode where Terminal stores its
settings in a `settings` folder next to `WindowsTerminal.exe`.
## Inspiration
- [PortableApps](https://portableapps.com)
- "Embeddable" Python, which relies on the deployment of a specific file to the Python root
## Solution Design
- _If running without package identity,_ `CascadiaSettings` will look for the presence of a file called `.portable` next
to `Microsoft.Terminal.Settings.Model.dll`.
- If that file is present, it will change the settings and state paths to be rooted in a subfolder named `settings` next
to `Microsoft.Terminal.Settings.Model.dll`.
Right now, _the only thing_ that makes Terminal not work in a "portable" manner is that it saves settings to
`%LOCALAPPDATA%`.
## UI/UX Design
_No UI/UX impact is expected._
## Capabilities
- Distributors could ship a self-contained and preconfigured Terminal installation.
- Users could archive fully-working preconfigured versions of Terminal.
- Developers (such as those on the team) could easily test multiple versions of Terminal without worrying about global
settings pollution.
### Accessibility
_No change is expected._
### Security
_No change is expected._
### Reliability
More code always bears a risk.
### Compatibility
This is a net new feature, and it does not break any existing features. A distributor (or a user) can opt in (or out) by
adding (or removing) the `.portable` file.
The following features may be impacted.
- **Dynamic Profiles** and **Fragment Extensions**
- _No impact expected._ Dynamic profiles will still be generated. If a portable installation is moved to a machine without the dynamic profile source, that profile will disappear.
-`firstWindowPreference` and `state.json`
- _No impact expected._
- State is stored next to settings, even for portable installations.
- If a dynamic profile was saved in `state` and has been removed, Terminal will proceed as in non-portable mode.
- Moving an install from Windows 10 to Windows 11 and back
- _No impact expected._
- "Machine-specific" settings, like those about rendering and repainting
- _No impact expected._
- Terminal does not distinguish settings that are specific to a machine. These settings will move along with the portable install.
- The shell extension
- _No impact expected._
- The shell extension will not be registered with Windows.
- If we choose to register the shell extension, it is already prepared for running a version of WT from the same directory. Registering the portable shell extension will make it launch portable Terminal.
### Performance, Power, and Efficiency
_No change is expected._
## Potential Issues
- User confusion around where settings are stored.
## Future considerations
- In the future, perhaps `.portable` could itself contain a directory path into which we would store settings.
- We could consider adding an indicator in the Settings UI.
- Because we are using the module path of the Settings Model DLL, a future unpackaged version of the shell extension
that supports profile loading would read the right settings file (assuming it used the settings model.)
- If we choose to store the shell extension cache in the registry, we would need to avoid doing so in portable mode.
The release of Windows Terminal has served as a way to reinvigorate the command-line ecosystem on Windows by providing a modern experience that is consistently updated. This experience has caused faster innovation in the Windows command-line ecosystem that can be seen across various areas like expanded virtual terminal sequence support and enhanced accessibility. Command-line apps can now leverage these innovations to create a better experience for the end-user.
Since accessibility is a very broad area, this document is intended to present recent innovations in the accessibility space for the command-line ecosystem. Furthermore, it will propose additional improvements that can be made alongside key stakeholders that could benefit from such changes.
## Windows Command-line Ecosystem
### First-party terminals
For many years, Console Host (Conhost) was the only first-party terminal on Windows. In 2019, Windows Terminal was released to the world as an open source first-party terminal. Windows Terminal was distributed through the Microsoft Store and received regular updates throughout the year, much more frequently than Conhost. In October 2022, Windows Terminal was enabled as the default terminal on Windows.
A significant amount of code is shared between Conhost and Windows Terminal to create the terminal area. To enable an accessible experience for this area, a shared UI Automation provider was introduced in 2019[^1], enabling accessibility tools to navigate and read contents from the terminal area. In 2020, Windows Terminal was updated to dispatch UIA events signaling when the cursor position, text output, or selection changed; this left the work of identifying what changed in the output to the attached screen reader application[^2]. In 2022, Windows Terminal was updated to dispatch UIA notifications with a payload of what text was written to the screen[^3].
### Internal Partners
There are many first-party command-line applications on Windows. The following are a few examples of those that are regularly updated:
- [**GitHub CLI**](https://cli.github.com/): a tool that can be used to query and interact with GitHub repos (open source)
- [**Winget**](https://github.com/microsoft/winget-cli): a tool to install applications and other packages
- [**PSReadLine**](https://github.com/PowerShell/PSReadLine): a PowerShell module that enhances the input line experience
- [**Windows Subsystem for Linux (WSL)**](https://learn.microsoft.com/en-us/windows/wsl/): a tool to manage and run GNU/Linux environments without a traditional virtual machine
- [**PowerShell**](https://github.com/PowerShell/PowerShell): a cross-platform command-line shell (open source)
Additionally, CMD is a Windows-specific command-line shell. Though it is no longer being updated, it is still widely used.
### External Command-line Applications
There are many third-party command-line applications on Windows that are regularly updated.
The following examples take over the entire viewport:

## Accessibility tools and features
### Screen Readers
Windows is predominantly dominated by three major screen readers: Narrator, JAWS, and NVDA.
- **Narrator**: a free first-party screen reader that ships with Windows.
- **JAWS**: a third-party screen reader that requires an annual license to use.
- **NVDA**: a free third-party screen reader that is open source.
It's important to note that most users generally use NVDA or JAWS[^4], so it's very important to consider the experience under both of those screen readers.
### Miscellaneous User Tools
Windows has many built-in features that enable a more accessible experiences. The following is a list of Windows accessibility settings and tools that may have an impact on apps:
- **Text size setting**: dictates the default size of text throughout all of Windows
- **Always show scrollbars setting**: forces the scrollbars to always be expanded and shown. Generally, this setting is automatically respected when using the Windows UI library.
- **Transparency effects setting**: allows transparency effects within the Windows shell
- **Text cursor indicator**: displays a colorful UI over the text cursor to make it stand out more and easier to find. Note, this is powered by UI Automation selection changed events because an empty selection is the cursor's position.
- **Magnifier**: zooms the monitor to provide a closer look at the current mouse and cursor position. Note, this is powered by UI Automation selection changed events because an empty selection is the cursor's position.
- **Color filters**: manipulates displayed colors to address color-blindness
- **High contrast themes**: ensures all displayed content has a high contrast ratio. Generally, this setting is automatically respected when using the Windows UI library. However, non-WinUI surfaces (like the terminal area) need to do additional work to respect this.
- **Voice access**: enables users to interact with their PC using their voice. This is powered by UI Automation to identify what controls can be interacted with and how.
### Verification Tools
[Accessibility Insights](https://accessibilityinsights.io/) is a modern tool that can be used to test and understand accessibility issues on Windows. It comes with a built-in color contrast analyzer, a UI Automation event listener, and a UI Automation tree explorer. Additionally, it can be used to explore and interact with different control patterns using the same API screen readers and other accessibility tools rely on. Accessibility Insights is also capable of running automated tests in CI and locally to detect common and simple issues.
## Proposed Accessibility Improvements
### Respect Text Size OS setting
Windows Terminal has a profile setting for the font size (`"font"."size": <integer>`) which is then used when instantiating new terminal sessions. There should be a way to make the terminal font size respect the text size setting in Windows found in the Settings App > Accessibility > Text Size.
A possible solution is to scale the session's text size at runtime based on the OS setting. Furthermore, the Windows Terminal's settings UI should warn the user when they are attempting to modify the font size profile setting.
This is tracked by [Windows accessibility "text size" parameter ignored by terminal · Issue #13600](https://github.com/microsoft/terminal/issues/13600)
### Respect High Contrast Mode
When high contrast mode is enabled, any WinUI surfaces are automatically changed to respect the newly desired contrast mode. However, the terminal area does not. In 2021, the Delta E algorithm was added to Windows Terminal as a tool to improve color contrast in the terminal area if desired[^5]. In 2022, it was exposed via an `adjustIndistinguishableColors` profile setting with a variety of possible configurations[^6].
There are several possible solutions to this issue, which all should be exposed to the user. Such solutions include the following:
- Enabling `adjustIndistinguishableColors` automatically when high contrast mode is enabled
- This leverages the Delta E algorithm to force an adequate contrast ratio. The algorithm would need to be expanded to expose the threshold.
- Reducing the colors used to match the Windows Contrast Theme colors
- Edge uses this heuristic and it has the added benefit that Windows Terminal is respecting the user's high contrast theme set in the OS.
- Implementing the `DECSTGLT` escape sequence which enables switching between different color modes (one of which is monochrome)
Additionally, we should automatically make the terminal fully opaque and ignore the acrylic or traditional transparency setting.
This is tracked by [[Epic] Improved High Contrast support · Issue #12999](https://github.com/microsoft/terminal/issues/12999)
### Enhanced UI Automation movement mechanisms
UI Automation has an `ITextRangeProvider` interface that can be used to represent a span of text. These text ranges can then be manipulated to explore the text area. Such manipulations include moving either (or both) endpoint(s) to encompass a text unit or move by unit. UI Automation supports the following text units:
- Character
- Format
- Word
- Line
- Paragraph
- Page
- Document
Windows Terminal and Conhost implement this `ITextRangeProvider` interface. However, this implementation doesn't support all of the available text units. Though this is standard across other implementations, this provides an opportunity for growth.
#### UI Automation: Movement by page
Movement by page is a relatively abstract concept in terminals. Arguably, the viewport could be leveraged to be considered a "page", which would provide users with a quick way to navigate the buffer.
This is tracked by [UIA: support movement by page · Issue #13756](https://github.com/microsoft/terminal/issues/13756)
#### UI Automation: Movement by format
The terminal area supports various text decorations including but not limited to underlined, bold, and italic text. These text attributes were exposed via the `ITextRangeProvider` interface in [PR #10366](https://github.com/microsoft/terminal/pull/10336). UI automation has support for navigating through contiguous spans adhering to a text attribute, which could be useful to expose to UIA clients.
This is tracked by [UIA Formatted Text Navigation · Issue #3567](https://github.com/microsoft/terminal/issues/3567).
#### Movement by prompt
[PR #12948](https://github.com/microsoft/terminal/pull/12948) added support for scrollbar marks in Windows Terminal. As a part of this, an `experimental.autoMarkPrompts` profile setting registers scrollbar marks with each prompt when enabled. This is a fantastic way to navigate through the scroll history quickly and easily.
Though UI automation doesn't have a text unit for prompts, we could define a "paragraph" as the space between two prompts.
This issue is tracked by [megathread: Scrollbar Marks · Issue #11000](https://github.com/microsoft/terminal/issues/11000).
### Mark Mode support for degenerate range
[PR #13053](https://github.com/microsoft/terminal/pull/13053) added support for mark mode in Windows Terminal. Mark mode allows users to create and modify selections by exclusively using the keyboard. However, screen reader users have reported it as a strange experience because it always has a cell of text selected; this results in the screen reader reading "x selected, y unselected" as opposed to the expected "x" when moving the cursor around.
Unfortunately, the changes required to fix this are very extensive because selections are stored as two inclusive terminal coordinates, which makes it impossible to represent an empty selection.
This is tracked by [A11y: windows terminal emits selection/deselection events in mark mode when navigating with arrow keys · Issue #13447](https://github.com/microsoft/terminal/issues/13447).
### Search improvements
The search dialog can be used to perform a runtime query of the text buffer. However, in its current form, it does not count the total number of matches like other developer tools (i.e. Visual Studio Code). This work item tracks two things:
1. Support for counting the total number of matches
2. Displaying the number of results in the search box and announcing it via a UIA notification to the screen reader
Additional search features may fall into this including but not limited to:
- Highlight the search results in the scroll bar
- Successful searches should read the line where text was found (similar to VS Code experience)
It seems that UI Automation has no guidance for a consistent, good search experience on Windows. Noting that VS Code and Microsoft Word have two different search experiences, it may be valuable to create documentation and guidance for other developer tools on Windows to follow, thus helping to create a more consistent search experience.
This is tracked by [Search should display the number of results it finds · Issue #6319](https://github.com/microsoft/terminal/issues/6319) and [[JAWS] Search results read "results found" instead of something useful · Issue #14153](https://github.com/microsoft/terminal/issues/14153).
### Shell suggestions
Shells provide different forms of autocompletion. However, that autocompletion isn't necessarily an accessible experience. For example, CMD's standard autocompletion experience rewrites the "word". The screen reader rereads the new "word" properly, however, the user must cycle between the options until the desired one is shown. As another example,
PowerShell supports menu completion, where possible completions are displayed as a table of text and relevant help text is displayed. However, screen readers struggle with this because the entire menu is redrawn every time, making it harder to understand what exactly is "selected" (as the concept of selection in this instance is a shell-side concept represented by visual manipulation).
A possible solution is to introduce a new VT sequence to have the shell provide a payload. This payload can contain things like the suggested completion as well as associated help text. Such data can then be leveraged by Windows Terminal to create UI elements. Doing so leverages WinUI's accessible design. By designing a new VT sequence, other terminal emulators and CLI apps can opt-in to this functionality too.
This is tracked by [Enhance shell autocompletion with a cool new user interface and shell completion protocol · Issue #3121](https://github.com/microsoft/terminal/issues/3121).
### Scripts Panel
Common command-line experiences revolve around inputting a command into the shell and executing it. Expert command-line users can remember complex commands off the top of their heads. Windows Terminal could help users by storing complex commands. Furthermore, these commands should be able to be easily shared between users.
From an accessibility standpoint, this can be very useful for users with mobility issues, as it is particularly difficult to write complex commands quickly.
This is tracked by [Feature Request - Scripts Panel · Issue #1595](https://github.com/microsoft/terminal/issues/1595).
### Broadcast Input
Windows Terminal supports running multiple sessions at once across various panes, tabs, and windows. The broadcast input feature allows users to send input to multiple sessions at once.
From an accessibility standpoint, this can be very useful for users with mobility issues, as it is time consuming to write commands to multiple sessions quickly, particularly if those commands are complex.
This is tracked by [Support broadcast input? · Issue #2634](https://github.com/microsoft/terminal/issues/2634).
### UI Automation Notification Related Improvements
In 2022, Windows Terminal added UI Automation notifications that contained a payload of text output[^3]. This was done for various reasons. For one, Narrator was not reading new output by the terminal, and would require changes on their end to accomplish this. Another reason is that NVDA is unable to handle too many text changed events, which Conhost and Windows Terminal are both culprits of since they dispatch an event when text is written to the terminal output.
UIA notifications have provided many compatibility benefits since screen readers automatically read notifications they receive. Additionally, this has provided the possibility for major performance enhancements as screen readers may no longer be required to diff the text buffer and figure out what has changed. NVDA has prototyped listening to notifications and ignoring text changed events entirely[^7]. However, it reveals underlying challenges with this new model such as how to handle passwords. The proposals listed in this section are intended to have Windows Terminal achieve improved performance and accessibility quality.
#### VT Screen Reader Control
Some command-line applications are simply too difficult to create a consistent accessible experience. Applications that draw decorative content, for example, may have that content read by a screen reader.
In 2019, Daniel Imms wrote a spec proposing a VT sequence that can partially control the attached screen reader[^8]. This VT sequence consists of three main formats:
1. Stop announcing incoming data to the screen reader. The screen reader will resume announcing incoming data if any key is pressed.
2. Resume announcing incoming data to the screen reader.
3. Announce the associated string payload immediately.
Additionally, all three formats include a string payload that will be announced immediately by the screen reader (as is done with the third format).
JAWS and Narrator both immediately read UIA notifications as that is how Windows Terminal presents newly output text. As described earlier, NVDA currently has notifications disabled, but is prototyping moving towards a world where they can drop text diffing entirely in favor of this.
With Windows Terminal now dispatching UIA notifications, it would be relatively trivial for Windows Terminal to extract the string payload from the relevant VT sequences and present it in a new UIA notification. Additionally, an internal flag would be enabled to suppress UIA notifications for text output until the flag is flipped via a key press or the relevant VT sequence is received.
This is tracked by [Unable to use applications that hook the arrow keys using Windows Console Host. · Issue #13666](https://github.com/microsoft/terminal/issues/13666)
#### Screen Reader Backpressure Control Proposal
NVDA has reported issues where Windows Terminal sends too may text changed events at once, causing NVDA to hang. Several considerations have been made in this area to address this issue:
- **Batch notifications**: unhelpful because Terminal doesn't know how much text is intended to be output
- **Diff text before sending a notification**: same problem as above
- **Provide an API to throttle notifications**: causes a security risk for denial of service attacks
Surprisingly, UI Automation doesn't have a built-in way to handle backpressure. However, the appropriate fix here seems to be either on the UI Automation side to fix this for all UIA clients, or on the NVDA side to improve event handling.
This is tracked by [UIA: reduce number of extraneous text change events in conhost · Issue #10822](https://github.com/microsoft/terminal/issues/10822)
## Proposed Priorities
The following table assigns priorities to the aforementioned work items. These priorities are solely based on accessibility impact to improve the Windows command-line ecosystem.
| Priority | Work Item | Reasoning |
|----------|-----------|-----------|
| 1 | VT Screen Reader Control | Several partners (both CLI apps and UIA clients) would benefit from this feature and have expressed interest in adopting it. |
| 1 | Shell suggestions | Several partners (both CLI apps and UIA clients) would benefit from this feature and have expressed interest in adopting it. |
| 1 | Search improvements | Search is very difficult to use in its current implementation. |
| 1 | Mark Mode support for degenerate range | Experience is barely usable and very unfriendly for non-sighted users. This is the only non-mouse method to select text. |
| 2 | Respect High Contrast Mode | Clear workarounds exist, but the golden path scenario fails where a user enables high contrast mode and content does not respect it. |
| 2 | Text Size OS Setting | Clear workarounds exist, but the golden path scenario fails where a user enables an OS setting and content does not respect it. |
| 2 | Broadcast Input | Users with mobility issues would greatly benefit from this. |
| 3 | Scripts Panel | Send-input commands currently exist. This would just expose it better. |
| 3 | UIA: Move to prompt | Additional UIA text unit support is good. |
| 3 | UIA: Move by page | Additional UIA text unit support is good. |
| 3 | UIA: Move by format | Additional UIA text unit support is good. |
Generally, the reasoning behind these priorities can be broken down as follows:
- Priority 1 bucket:
- These work items provide access to features within the command-line ecosystem that are practically unusable for users with accessibility needs.
- Priority 2 bucket:
- Active workarounds exist for these issues, but they could be cumbersome.
- Priority 3 bucket:
- Purely innovative ideas that provide an exceptional experience for users.

## What should be done to update this in the future?
1. Download the version of boost you want from boost.org.
2. Take the parts you want, but leave most of it behind since it's HUGE and will bloat the repo to take it all. At the time of this writing, we only use small_vector.hpp and its dependencies as a header-only library.
3. Validate that the license in the root of the repository didn't change and update it if so. It is sitting in a version-specific subdirectory below 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.
# error "Boost.Config is older than your compiler - please check for an updated Boost release."
