This is in advance of the UWP/WPF unification work, where we need to
provide a dispatcher from the WPF side. It should be a no-op today, but
we could also move _loading_ the dispatcher up to TermControl (XAML).
## Summary of the Pull Request
Updates the cached hovered hyperlink whenever a scroll occurs. All
changes were made in `ControlCore`:
- Add `_refreshHoveredCell()` which simply sets the hovered cell again
- Calls the new function in `UserScrollViewport()` for user-initiated
scrolling and `updateScrollBar` for non-user-initiated scrolling
## Validation Steps Performed
With multiple hyperlinks in the text buffer, the following scenarios
resulted in the hovered hyperlink being updated properly:
✅ mouse wheel scrolling
✅ keyboard scrolling
✅ scroll to mark

This is a trivial fix for an issue we get a somewhat outsized number of
complaints about.
When the user has adjusted the font size in any direction, we'll just
keep track of the magnitude and apply it every time the settings change.
Yes, this means that if you zoom once and then change your real font
size it's going to zoom even more.
That probably doesn't matter.

## Summary of the Pull Request
I was becoming frustrated with getting in a state where a CLI app (i.e.
Copilot CLI) enters some VT state (like mouse mode) then doesn't unset
it when it accidentally exits. I normally use "Restart connection" to
keep the buffer and connect again. Problem is, "restart connection"
didn't actually reset the internal state! So I would type and get a
bunch of lingering VT escape sequences. This bug is tracked over in
#18425 in a more generic way.
This fixes that bug by doing the following:
- update `ITermDispatch::HardReset()` -->`HardReset(bool erase)`
- `erase=true` does what `HardReset()` already did
- `erase=false` skips over clearing the screen and resetting the cursor
position
- expose `HardReset(false)` as `HardResetWithoutErase()` by piping it up
through `Terminal` --> `ControlCore` --> `TermControl`
- update the restart connection handler
- `TerminalPage::_restartPaneConnection()` now calls
`HardResetWithoutErase()` before setting the new connection
- this is also the same route for the "Enter to restart connection"
scenario (text displayed when connection ends)
Relevant notes from PR discussion:
- `PSEUDOCONSOLE_INHERIT_CURSOR` is passed into the new connection via
`_restartPaneConnection()` --> `_duplicateConnectionForRestart()` -->
`_CreateConnectionFromSettings(profile,
*controlSettings.DefaultSettings(), true)`
## Validation Steps Performed
- Used this to enter mouse tracking mode: `Write-Host -NoNewline
"`e[?1003h`e[?1006h"`
- mouse selection doesn't work as usual (expected)
- invoke "restart connection" action
- mouse selection works as usual
Closes#18425
This adds support for OSC 7 which is the same as OSC 9;9 but using
file URIs. As per the previous discussion in #8214, the problem is
that WSL shells emit URIs that can't work because the hostname in
the URI translates to an UNC path with an non-existing hostname.
In my opinion this doesn't deter the fact though that OSC 7 works
just fine for a native Windows application.
In the future we should consider trying to detect WSL file URIs
and translating it to the `--cd` argument for `wsl.exe`.
All of the heavy lifting for parsing the URI is done by
`PathCreateFromUrlW`. It just had to be plugged into the OSC 9;9 code.
Closes#3158
## Validation Steps Performed
* Launch fish-shell in WSL
* Duplicate tab works ✅
* (And because it doesn't work without using
`IsValidDirectory` I know that OSC 7 works ✅)
When text scrolls in and out of view, depending on the length
of the scrollback and latency of input, `GetSearchHighlightFocused`
would change which would trigger a `ScrollToSearchHighlight` call.
This PR changes the behavior such that only actively changing the
search mask triggers a search (typing text or pressing enter).
Closes#19754
## Validation Steps Performed
* Brining text in and out of view doesn't scroll ✅
* Toggling the aA button scrolls results into view ✅
This commit also ups the number of render failures that are permissible
to 6 (one try plus 5 retries), and moves us to use an exponential
backoff rather than a simple geometric one.
It also suppresses the dialog box in case of present failures for Stable
users. I feel like the warning dialog should be used for something that
the user can actually do something about...
Closes#15601Closes#18198
Previously, launching an unelevated session after an elevated one would
delete the latter's persisted buffers, and vice versa of course. Also,
elevated buffers didn't have an ACL forbidding access to unelevated
users. That's also fixed now.
Closes#19526
## Validation Steps Performed
* Unelevated/elevated WT doesn't erase each other's buffers ✅
* Old buffers named `buffer_` are renamed to `elevated_` if needed ✅
This PR moves the cursor blinker and VT blink rendition timer into
`Renderer`. To do so, this PR introduces a generic timer system with
which you can schedule arbitrary timer jobs. Thanks to this, this PR
removes a crapton of code, particularly throughout conhost.
## Validation Steps Performed
* Focus/unfocus starts/stops blinking ✅
* OS-wide blink settings apply on focus ✅
The idea with IControlSettings (and friends) was always that a consumer
of the terminal control could implement it in whatever way they pleased.
Windows Terminal (the application) was intended to be only one
consumer. It has a whole JSON settings model. Nobody wants to think
about JSON at the Terminal Control level. We could have an "adapter" in
TerminalApp, which spoke Terminal JSON Settings on one side and Terminal
Control on the other side.
That worked until we added the settings editor. The settings editor
needed to display a control, and that control's settings needed to be
based on the JSON settings. Oops. We took the expedient route of moving
the adapter into TerminalSettingsModel itself, and poking a bunch of
holes in it so that TerminalApp and TerminalSettingsEditor could tweak
it as needed.
Later, we doubled down on the control settings interface by having every
Terminal Control _make its own ControlSettings_ when we were going to do
the multi-process model. This reduced the number of IPC round trips for
every settings query to 0. Later we built color scheme previewing on top
of that--adding structs to carry color schemes and stuff which was
already in the Appearance config. Sheesh. Layers and layers and layers.
This pull request moves it back into its own library and strips it from
the surface of TerminalSettingsModel. It also deletes `ControlSettings`
and `struct CoreScheme`. That library is called
`TerminalSettingsAppAdapterLib`, and it contains a hidden WinRT
_implements_ type rather than a full-fledged activatable `runtimeclass`.
It also implements one-level inheritance on its own rather than using
IInheritable.
It adheres to the following principles:
- The control will never modify its settings in a way that is visible to
the control's consumer; therefore, none of the properties have setters
- The settings should never contain things of interest only to the
Application that the Application uses to communicate data _back to
itself_ (see `ProfileName`, removed in 68b723c and `KeyBindings`,
removed in fa09141). This generalizes to "we should never store stuff
in an unrelated object passed between layers solely for the purpose of
getting it back".
I made a few changes to the settings interface, including introducing a
new `ICoreScheme` interface that _only_ contains color scheme info. This
is designed to support the Preview/Set color scheme actions, which no
longer work by _app backing up the scheme and restoring it later._ All
of that machinery lives inside TermControl/ControlCore now.
`ICoreScheme` no longer supports `GetColorAtIndex`; you must read all 16
colors at the same time. I am not sorry. Every consumer did that
already, so now we have 15 fewer COM calls for every color scheme.
The new TerminalSettings is mostly consumed via
`com_ptr<TerminalSettings>`, so a bunch of `.` (projected) accesses had
to turn into `->` (com_ptr dereferencing) accesses.
I also realized, in the course of this work, that the old
TerminalSettings contained a partial hand-written reimplementation of
_every setting_ in `ControlProperties`. Every contributor had to add
every new setting to both places--why? I can't figure it out. I'm using
ControlProperties comprehensively now. I propagated any setting whose
default value was different from that in ControlProperties back to
ControlProperties.
This is part X in a series of pull requests that will remove all mention
of Microsoft.Terminal.Control and Microsoft.Terminal.Core from the
settings model. Once that is done, the settings model can consume _only_
the base WinRT types and build very early and test more easily.
Previewing is fun. I introduced a new place to stash an entire color
table on ControlCore, which we use to save the "active" colors while we
temporarily overwrite them. SetColorScheme is _also_ fun. We now have a
slot for overriding only the focused color scheme on ControlCore. It's
fine. It's clearer than "back up the focused appearance, overwrite the
focused appearance, create a child of the user's settings and apply the
color scheme to it, etc.".
There is a bug/design choice in color scheme overriding, which may or
may not matter: overlaying a color scheme on a terminal with an
unfocused appearance which _does not_ have its own color scheme will
result in the previously-deleted overridden focused color scheme peeking
through when the terminal is not focused.
I also got rid of our only in-product use of
`Terminal::CreateFromSettings` which required us to set `InitialRows`
and `InitialCols` on the incoming settings object (see core tenet 2).

For some reason, we went real hard on an architecture where the settings
object contained the key bindings handler for the terminal. To make this
work, we had to wind it through tons of layers: `TermControl`,
`ControlInteractivity`, `ControlCore` (which saved it on
`ControlSettings`), `ControlSettings`. Of course, because we have no
clear delineation of concerns at the App layer this required us to put
the bindings into the Settings Cache[^1].
Well, `TermControl` used `ControlCore` to get the Settings, to get the
Bindings, to dispatch keys.
Yes, `TermControl` stored `IKeyBindings` down three layers _only to fish
it back out and use it itself._
There is one place in the application where `TermControl`s are hooked up
to their owners. Instead of passing the key bindings dispatcher in
through nine hundred layers, we can just set it once--definitively!--
there.
[^1]: This was the last thing that made the settings cache
page-specific...
* Moves clipboard writing from `ControlCore` to `TerminalPage`.
This requires adding a bunch of event types and logic.
This is technically not needed anymore after changing the
direction of this PR, but I kept it because it's better.
* Add a `WarnAboutMultiLinePaste` enum to differentiate between
"paste without warning always/never/if-bracketed-paste-disabled".

If High Contrast mode is enabled in the OS settings, we now
automatically enable `adjustIndistinguishableColors`. To accomplish
this, a new `Automatic` value is added to
`adjustIndistinguishableColors`. When it's chosen, color nudging doesn't
occur in regular contrast sessions, but we interpret the value as
`Indexed` respectively.
The new default value is `AutomaticIndexed`. Meaning that regular
contrast sessions will see no difference in behavior. However, if they
switch to high contrast mode, Windows Terminal will interpret the value
as `Indexed` at runtime. This was chosen because `Always` is more
performance intensive.

✅ Toggling High Contrast mode immediately triggers an updated terminal
instance with `adjustIndistinguishableColors`
I found multiple issues while investigating this:
* Render thread shutdown is racy, because it doesn't actually stop the
render thread.
* Lifetime management in `ControlCore` failed to account for the
circular dependency of render thread --> renderer --> render data -->
terminal --> renderer --> render thread. Fixed by reordering the
`ControlCore` members to ensure their correct destruction.
* Ensured that the connection setter calls close on the previous
connection.
(Hopefully) Closes#18598

## Summary of the Pull Request
This extends the copy command to be able to include control sequences,
for use in tools that subsequently know how to parse and display that.
## References and Relevant Issues
https://github.com/microsoft/terminal/issues/15703
## Detailed Description of the Pull Request / Additional comments
At a high level, this:
- Expands the `CopyTextArgs` to have a `withControlSequences` bool.
- Plumbs that bool down through many layers to where we actuall get
data out of the text buffer.
- Modifies the existing `TextBuffer::Serialize` to be more generic
and renames it to `TextBuffer::ChunkedSerialize`.
- Uses the new `ChunkedSerialize` to generate the data for the copy
request.
## Validation Steps Performed
To test this I've manually:
- Generated some styled terminal contents, copied it with the control
sequences, pasted it into a file, `cat`ed the file and seen that it
looks the same.
- Set `"firstWindowPreference": "persistedWindowLayout"` and
validated that the contents of windows are saved and
restored with styling intact.
I also checked that `Invoke-OpenConsoleTests` passed.

This fixes a lot of subtle issues:
* Avoid emitting another de-/iconify VT sequence when
we encounter a (de)iconify VT sequence during parsing.
* Avoid emitting a de-/iconify VT sequence when
a focus event is received on the signal pipe.
* Avoid emitting such sequences on startup.
* Avoid emitting multiple such sequences
when rapidly un-/focusing the window.
It's also a minor cleanup, because the `GA_ROOTOWNER` is not security
relevant. It was added because there was concern that someone can just
spawn a ConPTY session, tell it that it's focused, and spawn a child
which is now focused. But why would someone do that, when the console
IOCTLs to do so are not just publicly available but also documented?
I also disabled the IME window.
## Validation Steps Performed
* First:
```cpp
int main() {
for (bool show = false;; show = !show) {
printf(show ? "Show in 3s...\n" : "Hide in 3s...\n");
Sleep(3000);
ShowWindow(GetConsoleWindow(), show ? SW_SHOW : SW_HIDE);
}
}
```
* PowerShell 5's `Get-Credential` gains focus ✅
* `sleep 5; Get-Credential` and focus another app. WT should start
blinking in the taskbar. Restore it. The popup has focus ✅
* Run `:hardcopy` in vim: Window is shown centered at (0,0) ✖️
But that's okay because it does that already anyway ✅
* `Connect-AzAccount` doesn't crash PowerShell ✅
* Don't reset the position entirely when changing the needle
* Don't change the scroll position when output arrives
* Don't interfere with the search when output arrives constantly
Closes#17301
## Validation Steps Performed
* In pwsh, run `10000..20000 | % { sleep 0.25; $_ }`
* You can search for e.g. `1004` and it'll find 10 results. ✅
* You can scroll up and down past it and it won't snap back
when new output arrives. ✅
* `while ($true) { Write-Host -NoNewline "`e[Ha"; sleep 0.0001; }`
* You can cycle between the hits effortlessly. ✅ (This tests that
the constantly reset `OutputIdle` event won't interfere.)
* On input change, the focused result is near the previous one. ✅
`ResizeWindow` event in `TerminalApi` is handled and bubbled to
`TerminalApi->ControlCore->TermControl->TerminalPage->AppHost`. Resizing
is accepted only if the window is not in fullscreen or quake mode, and
has 1 tab and pane.

This PR clones `winrt::fire_and_forget` and replaces the uncaught
exception handler with one that logs instead of terminating.
My hope is that this removes one source of random crashes.
## Validation Steps Performed
I added a `THROW_HR` to `TermControl::UpdateControlSettings`
before and after the suspension point and ensured the application
won't crash anymore.
* Repurposes `_sendInputToConnection` to send output to the connection
no matter whether the terminal is read-only or not.
Now `SendInput` is the function responsible for the UI handling.
* Buffers responses in a VT string into a single string
before sending it as a response all at once.
This reduces the chances for the UI thread to insert cursor positions
and similar into the input pipe, because we're not constantly unlocking
the terminal lock anymore for every response. The only way now that
unrelated inputs are inserted into the input pipe is because the VT
requests (e.g. DA1, DSR, etc.) are broken up across >1 reads.
This also fixes VT responses in read-only panes.
Closes#17775
## Validation Steps Performed
* Repeatedly run `echo ^[[c` in cmd.
DA1 responses don't stack & always stay the same ✅
* Run nvim in WSL. Doesn't deadlock when pasting 1MB. ✅
* Run the repro from #17775, which requests a ton of OSC 4
(color palette) responses. Jiggle the cursor on top of the window.
Responses never get split up. ✅
## Summary of the Pull Request
Improves Quick Fix's suggestions to use WinGet API and actually query
winget for packages based on the missing command.
To interact with the WinGet API, we need the
`Microsoft.WindowsPackageManager.ComInterop` NuGet package.
`Microsoft.WindowsPackageManager.ComInterop.Additional.targets` is used
to copy over the winmd into CascadiaPackage. The build variable
`TerminalWinGetInterop` is used to import the package properly.
`WindowsPackageManagerFactory` is used as a centralized way to generate
the winget objects. Long-term, we may need to do manual activation for
elevated sessions, which this class can easily be extended to support.
In the meantime, we'll just use the normal `winrt::create_instance` on
all sessions.
In `TerminalPage`, we conduct the search asynchronously when a missing
command was found. Search results are limited to 20 packages. We try to
retrieve packages with the following filters set, then fallback into the
next step:
1. `PackageMatchField::Command`,
`PackageFieldMatchOption::StartsWithCaseInsensitive`
2. `PackageMatchField::Name`,
`PackageFieldMatchOption::ContainsCaseInsensitive`
3. `PackageMatchField::Moniker`,
`PackageFieldMatchOption::ContainsCaseInsensitive`
This aligns with the Microsoft.WinGet.CommandNotFound PowerShell module
([link to relevant
code](9bc83617b9/src/WinGetCommandNotFoundFeedbackPredictor.cs (L165-L202))).

## Summary of the Pull Request
Adds a scroll offset to avoid hiding the current search highlight with
the search box.
- Offset is based on the number of rows that the search box takes up.
(I am not totally sure I am calculating this right)
- This won't help when the current highlight is in the first couple
rows of the buffer.
Fixes: #4407
This PR adds the ability to load snippets from the CWD into the
suggestions UI.
If shell integration is disabled, then we only ever think the CWD for a
pane is it's `startingDirectory`. So, in the default case, users can
still stick snippets into the root of their git repos, and have the
Terminal load them automatically (for profiles starting in the root of
their repo).
If it's enabled though, we'll always try to load snippets from the CWD
of the shell.
* We cache the actions into a separate map of CWD -> actions. This lets
us read the file only the first time we see a dir.
* We clear that cache on settings reload
* We only load `sendInput` actions from the `.wt.json`
As spec'd in #17329
### `OSC 9001; CmdNotFound; <missingCmd>`
Adds support for custom OSC "command not found" sequence `OSC 9001;
CmdNotFound; <missingCmd>`. Upon receiving the "CmdNotFound" variant
with the missing command payload, we send the missing command up to the
Quick Fix menu and add it in as `winget install <missingCmd>`.
### Quick Fix UI
The Quick Fix UI is a new UI surface that lives in the gutter (left
padding) of your terminal. The button appears if quick fixes are
available. When clicked, a list of suggestions appears in a flyout. If
there is not enough space in the gutter, the button will be presented in
a collapsed version that expands to a normal size upon hovering over it.
The Quick Fix UI was implemented similar to the context menu. The UI
itself lives in TermControl, but it can be populated by other layers
(i.e. TermApp layer).
Quick Fix suggestions are also automatically loaded into the Suggestions
UI.
If a quick fix is available and a screen reader is attached, we dispatch
an announcement that quick fixes are available to notify the user that
that's the case.
Spec: #17005#16599

This adds support for previewing snippets, again. This time, with the
new TSF implementation. Leonard pointed me in the right direction with
this - he's the one who suggested to have a second `Composition` just
for previews like this.
Then we do some tricky magic to make it work when we're using
commandlines from shell integration, or you've got the ghost text from
powershell, etc. Then we visualize the control codes, just so they
aren't just U+FFFE diamonds.
Closes#12861
This addresses a review comment left by tusharsnx in #17092 which I
forgot to fix before merging the PR. The fix itself is somewhat simple:
`Terminal::SetSearchHighlightFocused` triggers a scroll if the target
is outside of the current (scrolled) viewport and avoiding the call
unless necessary fixes it. To do it properly though, I've split up
`Search::ResetIfStale` into `IsStale` and `Reset`. Now we can properly
detect staleness in advance and branch out the search reset cleanly.
Additionally, I've taken the liberty to replace the `IVector` in
`SearchResultRows` with a direct `const std::vector&` into `Searcher`.
This removes a bunch of code and makes it faster to boot.
## Validation Steps Performed
* Print lots of text
* Search a common letter
* Scroll up
* Doesn't scroll back down ✅
* Hold enter to search more occurrences scrolls up as needed ✅
* `showMarksOnScrollbar` still works ✅
This shouldn't have ever worked...? This looks like it was a typo and
should have been `mark.end`.
Thanks @joadoumie for asking about the moving the cursor in the prompt,
that convo lead to me finding this.
This PR extends `til::throttled_func` to also support debouncing:
* throttling: "At most 1 call every N seconds"
* debouncing: "Exactly 1 call after N seconds of inactivity"
Based on the latter the following series of changes were made:
* An `OutputIdle` event was added to `ControlCore` which is
raised once there hasn't been any incoming data in 100ms.
This also triggers an update of our regex patterns (URL detection).
* The event is then caught by `TermControl` which calls `Search()`.
* `Search()` in turn was modified to return its results by-value
as a struct, which avoids the need for a search-update event
and simplifies how we update the UI.
This architectural change, most importantly the removal of the
`TextLayoutUpdated` event, fixes a DoS bug in Windows Terminal:
As the event leads to UI thread activity, printing lots of text
continuously results in the UI thread becoming unresponsive.
On top of these, a number of improvements were made:
* `IRenderEngine::InvalidateHighlight` was changed to take the
`TextBuffer` by-reference which avoids the need to accumulate the
line renditions in a `std::vector` first. This improves Debug build
performance during reflow by what I guess must be roughly
a magnitude faster. This difference is very noticeable.
* When closing the search box, `ClearSearch()` is called to remove
the highlights. The search text is restored when it's reopened,
however the current search position isn't.
Closes#17073Closes#17089
## Validation Steps Performed
* UIA announcements:
* Pressing Ctrl+Shift+F the first time does not lead to one ✅
* Typing the first letter does ✅
* Closing doesn't ✅
* Reopening does (as it restores the letter) ✅
* Closing the search box dismisses the highlights ✅
* Resizing the window recalculates the highlights ✅
* Changing the terminal output while the box is open
recalculates the highlights ✅
While `double` is probably generally preferable for UI code,
our application is essentially a complex wrapper wrapper around
DWrite, D2D and D3D, all of which use `float` exclusively.
Of course it also uses XAML, but that one uses `float` for roughly
1/3rd of its API functions, so I'm not sure what it prefers.
Additionally, it's mostly a coincidence that we use WinUI/XAML for
Windows Terminal whereas DWrite/D2D/D3D are effectively essential.
This is demonstrated by the fact that we have a `HwndTerminal`,
while there's no alternative to e.g. D3D on Windows.
The goal of this PR is that DIP based calculations never end up
mixing `float` and `double`. This PR also changes opacity-related
values to `float` because I felt like that fits the theme.
Next in the popular series of minor refactorings:
Out with the old, in with the new!
This PR removes all of the existing TSF code, both for conhost and
Windows Terminal. conhost's TSF implementation was awful:
It allocated an entire text buffer _per line_ of input.
Additionally, its implementation spanned a whopping 40 files and
almost 5000 lines of code. Windows Terminal's implementation was
absolutely fine in comparison, but it was user unfriendly due to
two reasons: Its usage of the `CoreTextServices` WinRT API indirectly
meant that it used a non-transitory TSF document, which is not the
right choice for a terminal. A `TF_SS_TRANSITORY` document (-context)
indicates to TSF that it cannot undo a previously completed composition
which is exactly what we need: Once composition has completed we send
the result to the shell and we cannot undo this later on.
The WinRT API does not allow us to use `TF_SS_TRANSITORY` and so it's
unsuitable for our application. Additionally, the implementation used
XAML to render the composition instead of being part of our text
renderer, which resulted in the text looking weird and hard to read.
The new implementation spans just 8 files and is ~1000 lines which
should make it significantly easier to maintain. The architecture is
not particularly great, but it's certainly better than what we had.
The implementation is almost entirely identical between both conhost
and Windows Terminal and thus they both also behave identical.
It fixes an uncountable number of subtle bugs in the conhost TSF
implementation, as it failed to check for status codes after calls.
It also adds several new features, like support for wavy underlines
(as used by the Japanese IME), dashed underlines (the default for
various languages now, like Vietnamese), colored underlines,
colored foreground/background controlled by the IME, and more!
I have tried to replicate the following issues and have a high

For the following issues I'm not entirely sure if it'll fix it,
but I suspect it's somewhat likely:
#13681#16305#16817
Lastly, there's one remaining bug that I don't know how to resolve.
However, that issue also plagues conhost and Windows Terminal
right now, so it's at least not a regression:
* Press Win+. (emoji picker) and close it
* Move the window around
* Press Win+.
This will open the emoji picker at the old window location.
It also occurs when the cursor moves within the window.
While this is super annoying, I could not find a way to fix it.

### The changeset involves:
- Decoupling Selection and Search Highlighting code paths.
- We no longer invalidate search highlights when:
- Left-clicking on terminal
- A new selection is made
- Left-clicking on Search-box
- Dispatching Find Next/Prev Match Action. (The search highlight was
removed after pressing the first key of the Action's key combination)
- And, anything that doesn't change buffer content, shouldn't invalidate
the highlighted region (E.g. Cursor movement)
- Highlighting foreground color is *actually* applied to the highlighted
text.
- Double-clicking on SearchBox no longer starts a text selection in the
terminal.
- Selected text is properly populated in the Search Box (#16355)
Closes: #16355

## Some Implementation Details
### Detecting text layout changes in the Control layer
As Search Highlight regions need to be removed when new text is added,
or the existing text is re-arranged due to window resize or similar
events, a new event `TextLayoutUpdated` is added that notifies
`CoreControl` of any text layout changes. The event is used to
invalidate and remove all search highlight regions from the buffer
(because the regions might not be _fresh_ anymore.
The new event is raised when:
1. `AdaptDispatch` writes new text into the buffer.
2. MainBuffer is switched to AltBuffer or vice-versa.
3. The user resized the window.
4. Font size changed.
5. Zoom level changed.
(Intensionally,) It's not raised when:
1. Buffer is scrolled.
2. The text cursor is moved.
When `ControlCore` receives a `TextLayoutUpdated` event, it clears the
Search Highlights in the *render data*, and raises an
`UpdateSearchResults` event to notify `TermControl` to update the Search
UI (`SearchBoxControl`).
In the future, we can use `TextLayoutUpdated` event to start a new
search which would refresh the results automatically after a slight
delay (throttled). *VSCode already does this today*.
### How does AtlasEngine draw the highlighted regions?
We follow a similar idea as for drawing the Selection region. When new
regions are available, the old+new regions are marked invalidated.
Later, a call to `_drawHighlighted()` is made at the end of
`PaintBufferLine()` to override the highlighted regions' colors with
highlight colors. The highlighting colors replace the buffer colors
while search highlights are active.
Note that to paint search highlights, we currently invalidate the row
completely. This forces text shaping for the rows in the viewport that
have at least one highlighted region. This is done to keep the (already
lengthy) PR... simple. We could take advantage of the fact that only
colors have changed and not the characters (or glyphs). I'm expecting
that this could be improved like:
1. When search regions are added, we add the highlighting colors to the
color bitmaps without causing text shaping.
2. When search regions are removed, we re-fill the color bitmaps with
the original colors from the Buffer.
## Validation Steps:
- New text, window resize, font size changes, zooming, and pasting
content into the terminal removes search highlights.
- highlighting colors override the foreground and background color of
the text (in the rendered output).
- Blinking, faded, reverse video, Intense text is highlighted as
expected.
In the spirit of #15360 this implements the copy part.
The problem is that we have an issue accessing the clipboard while
other applications continue to work just fine. The major difference
between us and the others is that we use the WinRT clipboard APIs.
So, the idea is that we just use the Win32 APIs instead.
The feel-good side-effect is that this is (no joke) 200-1000x faster,
but I suspect no one will notice the -3ms difference down to <0.01ms.
The objective effect however is that it just works.
This may resolve#16982.
## Validation Steps Performed
* Cycle through Text/HTML/RTF-only in the Interaction settings
* Paste the contents into Word each time
* Text is plain and HTML/RTF are colored ✅
This is pretty much a huge refactoring of how marks are stored in the
buffer.
Gone is the list of `ScrollMark`s in the buffer that store regions of
text as points marking the ends. Those would be nigh impossible to
reflow nicely.
Instead, we're going to use `TextAttribute`s to store the kind of output
we've got - `Prompt`, `Command`, `Output`, or, the default, `None`.
Those already reflow nicely!
But we also need to store things like, the exit code for the command.
That's why we've now added `ScrollbarData` to `ROW`s. There's really
only going to be one prompt->output on a single row. So, we only need to
store one ScrollbarData per-row. When a command ends, we can just go
update the mark on the row that started that command.
But iterating over the whole buffer to find the next/previous
prompt/command/output region sounds complicated. So, to avoid everyone
needing to do some variant of that, we've added `MarkExtents` (which is
literally just the same mark structure as before). TextBuffer can figure
out where all the mark regions are, and hand that back to callers. This
allows ControlCore to be basically unchanged.
_But collecting up all the regions for all the marks sounds expensive!
We need to update the scrollbar frequently, we can't just collect those
up every time!_ No we can't! But we also don't need to. The scrollbar
doesn't need to know where all the marks start and end and if they have
commands and this and that - no. We only need to know the rows that have
marks on them. So, we've now also got `ScrollMark` to represent just a
mark on a scrollbar at a specific row on the buffer. We can get those
quickly.
* [x] I added a bunch of tests for this.
* [x] I played with it and it feels good, even after a reflow (finally)
* See:
* #11000
* #15057 (I'm not marking this as closed. The stacked PR will close
this, when I move marks to Stable)
This changeset allows Windows Terminal to dump its buffer contents as
UTF-16LE VT text onto disk and restore it later. This functionality is
enabled whenever `persistedWindowLayout` is being used.
Closes#961Closes#16741
## Validation Steps Performed
* Open multiple windows with multiple tabs and restart the app
Everything's restored ✅
* Reopen a tab with output from `RenderingTests.exe`
Everything's restored ✅
* Closing tabs and windows with Ctrl+W deletes their buffer dumps ✅
* Closing tabs doesn't create buffer dumps ✅
This adds support for specifying more than one font family using a
syntax that is similar to CSS' `font-family` property.
The implementation is straight-forward and is effectively
just a wrapper around `IDWriteFontFallbackBuilder`.
Closes#2664

This implements `SetForceFullRepaintRendering` and adds a new
`SetGraphicsAPI` function. The former toggles `Present1` on and off
and the latter allows users to explicitly request Direct2D/3D.
On top of these changes I did a minor cleanup of the interface,
because now that DxRenderer is gone we don't need all that anymore.
Closes#14254Closes#16747
## Validation Steps Performed
* Toggling Direct2D on/off changes colored ligature support ✅
* Toggling Present1 on/off can be observed in a debugger ✅
* Toggling WARP on/off changes GPU metrics ✅

This PR automagically finds and replaces all[^1] usages of our
TYPED_EVENT macro with `til::event`. Benefits include:
* less macro magic
* editors are more easily able to figure out the relationship between
`til::event<> Foo;`, `Foo.raise(...)`, and `bar.Foo({this,
&Bar::FooHandler})` (whereas before the relationship between
`_FooHandlers(...)` and `bar.Foo({...})`) couldn't be figured out by
vscode & sublime.
Other find & replace work that had to be done:
* I added the `til::typed_event<>` == `<IInspectable, IInspectable>`
thing from #16170, since that is goodness
* I actually fixed `til::property_changed_event`, so you can use that
for your property changed events. They're all the same anyways.
* events had to come before `WINRT_PROPERTY`s, since the latter macro
leaves us in a `private:` block
* `Pane::SetupChildCloseHandlers` I had to swap _back_, because the
script thought that was an event 🤦
* `ProfileViewModel::DeleteProfile` had to be renamed
`DeleteProfileRequested`, since there was already a `DeleteProfile`
method on it.
* WindowManager.cpp was directly wiring up it's `winrt::event`s to the
monarch & peasant. That doesn't work with `til::event`s and I'm kinda
surprised it ever did

This pull request introduces support for disabling full-color emoji (and
technically other COLR-related font features!)
Full-color emoji don't respond to SGR colors, intensity, faint or blink.
Some users also just prefer the line art ones.
