This new preview text contains:
* Bold text, which is controlled by intenseTextStyle
* Colors

Oklab by Björn Ottosson is a color space that has less irregularities
than the CIELAB color space used for ΔE2000. The distance metric for
Oklab (ΔEOK) is defined by CSS4 as the simple euclidian distance.
This allows us to drastically simplify the code needed to determine
a color that has enough contrast. The new implementation still lacks
proper gamut mapping, but that's another and less important issue.
I also made it so that text with the dim attribute gets adjusted just
like regular text, since this is an accessibility feature after all.
The new code is so much faster than the old code (12-125x) that I
dropped any caching code we had. While this increases the CPU overhead
when printing lots of indexed colors, the code is way less complex now.
"Increases" in this case however means something in the order of 15-60ns
per color change (as measured on my CPU). It's possible to further
improve the performance using explicit SIMD instructions, but I've
left that as a future improvement, since that will make the code quite
a bit more verbose and I didn't want to hinder the initial review.
Finally, these new routines are also used for ensuring that the
AtlasEngine cursors remains visible at all times.

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).

## Summary of the Pull Request
There are certain escape sequences that use the `VTParameters::subspan`
method to access a subsection of the provided parameter list. When the
parameter list is empty, that `subspan` call can end up using an offset
that is out of range, which causes the terminal to crash. This PR stops
that from happening by clamping the offset so it's in range.
## References and Relevant Issues
This bug effected the `DECCARA` and `DECRARA` operations introduced in
PR #14285, and the `DECPS` operation introduced in PR #13208.
## Validation Steps Performed
I've manually confirmed that the sequences mentioned above are no longer
crashing when executed with an empty parameter list, and I've added a
little unit test that checks `VTParameters::subspan` method is returning
the expected results when passed an offset that is out of range.

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.
System menu opens as it should.

## 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`.

Warning shows up when a non-monospaced font is selected either globally
or on individual profiles. All existing tests continue to pass.

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.

2. A new indicator in the settings UI plus a link to the portable mode

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.

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

The result is not identical to the old shader, as the older shader

the result looked way fatter than it was seemingly originally intended.

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.

infeasible (and also _horrible_) to use it.

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.

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.

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.

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

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.

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`.

ColorScheme MVVM was implemented in #13179. This PR updates the
ProfileViewModel/AppearanceViewModels to use color scheme view models
instead of the raw settings model objects.

## 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.
Closes#14558
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.

## 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
the `HwndTerminal::Refresh` which was the entrypoint causing the issue.

## 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

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.

screen.

## 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

tainted by undefined behavior, so the most likely affect this had is that
we were reading uninitialized memory.

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.

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.

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

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.

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.
Validation:
When bound to Alt+Space, the system menu works in the command palette,
the settings UI, and in read-only panes.

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

* 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 fixes#3454 by adding support for an "always" mode for the scroll bar.
This change uses a custom VisualStateManager to keep the scroll bar from collapsing if the profile is using the 'always' setting.
## Validation Steps Performed
Tried updating settings.json directly and using the UI and making sure the scroll bar behaves as expected.
Closes#3454

There's a different behavior regarding cursors between conhost and Windows
Terminal. In case of the latter we don't necessarily call `PaintCursor`
during cursor movement, because the cursor blinker never stops "blinking".
Closes#14028
## Validation Steps Performed
* Enter text until after the line wraps
* Hold backspace until the line unwraps
* No leftover cursor on the second line ✅
This fixes an issue with c51bb3a, where some fractional font
sizes are displayed as something like 13.600000000001.
Closes#14024
## Validation Steps Performed
* Enter a font size of 13.6 and save
* NumberBox displays "13.6" ✅
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
## Validation Steps Performed
* Add a `THROW_HR(E_INVALIDARG);` in `AtlasEngine::StartPaint()`
* 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.
This commit makes sure to initialize the `cellGlyphMapping` buffer.
Additionally it clears the rest of the row with whitespace
until proper `LineRendition` support is added.
Closes#13962
## Validation Steps Performed
* vttest's "Test of double-sized characters" stops crashing ✅
* No weird leftover characters ✅
Direct3D 10.0 and 10.1 only have optional support for shader model 4.
This commit fixes our assumption that it's always present by checking
`ComputeShaders_Plus_RawAndStructuredBuffers_Via_Shader_4_x` first.
Closes#13985
## Validation Steps Performed
* Set feature level to 10.1 via `dxcpl`
* `CheckFeatureSupport` is called and doesn't throw ✅

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

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.

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.

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:
- [**Vim**](https://www.vim.org/): a modal-based text editor with an extensive plugin system
- **Emacs**: a shortcut-oriented text editor with an extensive plugin system
- [**Emacspeak**](https://emacspeak.sourceforge.net/): an Emacs subsystem that leverages Emacs' context-specific information to produce speech output
- **Midnight Commander**: a file manager with an extensive text user interface
- **Far Manager**: a file manager for Windows with an exclusive text user interface
- **tmux**: a terminal multiplexer
The following examples don't take over the entire viewport:
- [**Oh My Posh**](https://ohmyposh.dev/): a tool to customize shell prompts
- **git**: a tool for version control
The following examples operate as command-line shells:
- [**Bash**](https://www.gnu.org/software/bash/) is the default shell for most Linux distributions
- [**Fish shell**](https://fishshell.com/) provides a rich shell experience with features like autosuggestion support and VGA colors
- [**Z shell**](https://zsh.sourceforge.io/) is an extended Bourne shell
## 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.
