For some reason, Windows Terminal stops dispatching UIA TextChanged events sometimes. There isn't a reliable repro for this bug.
However, under NVDA's logger, it appears that when the bug does occur, we still dispatch UIA notifications (which may be ignored by NVDA in some configurations). A "quick fix" here is to dispatch a TextChanged event if we're going to dispatch a notification. Since we're just enabling a flag, we won't send two events at once.
Closes#10911
The `SignalTextChanged` crash seems to be occurring due to the `TermControlAutomationPeer` being destructed by the time the UIA event is actually dispatched. Even though we're already checking if TCAP and TermControl still exist, it could be that the TermControl is being closed as text is being output.
The proposed fix here is to record when the closing process starts and exposing that information directly to the TCAP. If TCAP sees that we're in the process of closing, don't bother sending a UIA event.
Closes#13978
Up until now, we have been relying on the catalog signature produced for our MSIX package.
There are some things (Packaged COM, Process Explorer as of 2022) that cannot handle catalog-signed
files. It's easier and safer for us to simply sign all the executables we produce before packaging them.
Unfortunately, we can't do it before we package them. We have to unpack and re-pack our package.
In the future, this will allow us to provide a codesigned distribution that is not in an MSIX package.
TEST=Ran a build and checked out the contents of the package. They were all signed!

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

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

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

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

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

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.

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

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

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

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

We couldn't do this before, because `App::Current().Resources().Lookup()` would always return the OS theme version of a resource. That thread has lengthy details on why.
FORTUNATELY FOR US, this isn't the first time we've dealt with this. We've come up with a workaround in the past, and we can just use it again here.
Closes#3917
This will also make #3061 easy 😉
## 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.

## 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.

Thanks to @KalleOlaviNiemitalo, we've been able to run a series of tests
on a real VT420, so we have a good idea of how these ops are intended to
work. Our implementation does a reasonably good job of matching that
behavior, but we don't yet support paging, so we don't have the `DECCRA`
ability to copy between pages, and we also don't have the concept of
"unoccupied" cells, so we can't support that aspect of the streaming
operations.
It's also worth mentioning that the VT420 doesn't have colors, so we
can't be sure exactly how they are meant to interpreted. However, based
on the way the other attribute are handled, and what we know from the
DEC STD 070 documentation, I think it's fair to assume that our handling
of colors is also reasonable.
Prior to this PR, the conhost vertical scrollbar would be forced to be
visible whenever the "Disable Scroll-Forward" option was set. It was
assumed that it would be needed as soon as the current viewport was
filled, so it was better to start off visible and disabled.
When the viewport height and buffer height are the same, though, the
scrollbar is never needed, and conhost compensates for that by making
the window narrower. But since we were still forcing the scrollbar to be
visible, that would result in it overlapping content in the rightmost
columns.
This PR attempts to fix that issue by simply leaving the scrollbar to
decide the visibility itself. This is perhaps not as aesthetically
pleasing when it starts off hidden and then later becomes visible, but
that seems better than having it overlap the content.
I've manually confirmed this fixes the problem reported in issue #2449.
Closes#2449
## Summary of the Pull Request
Compiler was raising the error: `expression did not evaluate to a constant.`, causing the solution to fail when building. Removing this `constexpr` fixes it.

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

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

XAML has an issue in windows 10 where `Width="*"` does not work properly
inside the `DataTemplate` for a `ListView`. Because of this, the color
scheme list view items looked very strange in windows 10 (see #14187).
Thanks to that, we thought up a few new designs for the color schemes
page and selected a new one that blends the color chips with a region
that shows the foreground and background color with the text preview.
Closes#14187
My hope with this commit is to make our code more robust against accidental
recursive locking, as well as making it easier to write code with confidence,
with only a slight performance trade-off.
## Validation Steps Performed
* Playing Pac Man music through MIDI ✅
* Windows Terminal runs happily ever after ✅
Silent MIDI notes can be used to seemingly deny a user's input for long
durations (multiple minutes). This commit improves the situation by ignoring
all DECPS sequences for a second when Ctrl+C/Ctrl+Break is pressed.
Additionally it fixes a regression introduced in 666c446:
When we close a tab we need to unblock/shutdown `MidiAudio` early,
so that `ConptyConnection::Close()` can run down as fast as possible.
## Validation Steps Performed
* In pwsh in Windows Terminal 1.16 run ``while ($True) { echo "`e[3;8;3,~" }``
* Ctrl+C doesn't do anything ❎
* Closing the tab doesn't do anything ❎
* With these modifications in Windows Terminal:
* Ctrl+C stops the output ✅
* Closing the tab completes instantly ✅
* With these modifications in OpenConsole:

* Closing the window completes instantly ✅
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.
Closes#12880
Lately I've been a bit concerned about issues resulting from b036cab enabling
`/fp:fast` throughout the entire project. This commit reverts that change and:
* Enables `/fp:contract` which defaults to off since VS 17.0
This re-enables FMA for floats on ARM64. Since this doesn't affect NANs, etc.
I don't expect any issues apart from a slight change in float accuracy.
* Introduces `TIL_FAST_MATH_BEGIN` with which `/fp:fast` can be selectively
enabled for code that benefits from it like `ColorFix.cpp`.
Without `TIL_FAST_MATH_BEGIN` `ColorFix` is about twice as slow
(which is actually very noticeable in real life).
This PR doesn't produce any noticeable performance regressions.

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

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

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

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

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

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

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

The breadcrumbs in the SUI were not readable by screen readers because they are represented as a button with a text block inside of it. Turns out, if you make the DataTemplate's item `IStringable` (meaning it has a `ToString()`), it all magically works! Allowing the screen reader to read the button as text.
Closes#13826
This PR adds support for the `DECARM` (Auto Repeat Mode) sequence, which
controls whether a keypress automatically repeats if you keep it held
down for long enough.
Note that this won't fully work in Windows Terminal until issue #8440 is
resolved.
Every time we receive a `KeyDown` event, we record the virtual key code
to track that as the last key pressed. If we receive a `KeyUp` event the
matches that last key code, we reset that field. Then if the Auto Repeat
Mode is reset, and we receive a `KeyDown` event that matches the last
key code, we simply ignore it.
## Validation Steps Performed
I've manually tested the `DECARM` functionality in Vttest and confirmed
that it's working as expected. Although note that in Windows Terminal
this only applies to non-alphanumeric keys for now (e.g. Tab, BackSpace,
arrow keys, etc.)
I've also added a basic unit test that verifies that repeated key
presses are suppressed when the `DECARM` mode is disabled.
Closes#13919
It turns out that the negative margin for the progress ring is causing
the clipping in case the tab title gets too long:
43dbbd590f/src/cascadia/TerminalApp/TabHeaderControl.xaml (L18-L27)
The negative margin was introduced in #8113 because the progress ring is
supposed to replace the tab icon but the `TabView` still reserves space
even if no icon is set (see
https://github.com/microsoft/terminal/pull/8133#issuecomment-739098014).
However, it is not actually the `TabView` reserving space even when
there is no icon, but a workaround for a crash in the
`IconPathConverter` that returns a `BitmapIconSource` with a `nullptr`
source instead of a `nullptr` `IconSource`:
43dbbd590f/src/cascadia/TerminalSettingsModel/IconPathConverter.cpp (L143-L154)
The workaround in `IconPathConverter` could probably be removed as I did
not find any instance where it is still used in a way that could trigger
the mentioned crash, but I did not dare to just remove it as I do not
know enough about the code by far. Hence, I opted to just locally
instantiate the `IconSource` with a `nullptr` directly in `TerminalTab`.
Fixes#8910
This PR adds support for the selective erase escape sequences: `DECSED`,
`DECSEL`, and `DECSCA`. They provide a way of marking certain areas of
the screen as "protected", so you can erase the content everywhere else
without affecting those protected areas.
This adds another bit in the `CharacterAttributes` enum to track the
protected status of each cell, and an operation triggered by the
`DECSCA` sequence which can toggle that bit in the active attributes.
There there are two new erase operations triggered by the `DECSED` and
`DECSEL` sequences, which work similar to the existing `ED` (erase in
display) and `EL` (erase in line) operations, but which only apply to
unprotected cells.
I've also updated the `DECRQSS` settings request, so you can query the
active protected attribute status.
## Validation Steps Performed
I've manually confirmed that we pass the selective erase tests in Vttest
now, and I've also manually tested some more complicated edge cases and
confirmed that we match the behavior of the hardware VT240 emulator in
MAME.
For unit testing I've extended the existing erase tests to cover
selective erase as an additional option, I've added a test covering the
`DECSCA` sequence, and I've extended the `DECRQSS` adapter test to
confirm the attribute reporting is working.
Closes#14029

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

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

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

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

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

This PR introduces a mechanism for passing through downloadable soft
fonts to the conpty client, so that we can support DRCS (Dynamically
Redefinable Character Sets) in Windows Terminal.
Soft fonts were first implemented in conhost (with the GDI renderer) in
PR #10011, and were implemented in the DX renderer in PR #13362.
The way this works is by passing through the `DECDLD` sequence
containing the font definition, but with the character set ID patched to
use a hardcoded value (this is to make sure it's not going to override
the default character set). At the same time we send through an `SCS`
sequence to map this character set into the G1 table so we can easily
activate it.
We still need to process the `DECDLD` sequence locally, though, since
the initial character set mapping take place on the host side. This gets
the DRCS characters into our buffer as PUA Unicode characters. Then when
the VT engine needs to output these characters, it masks them with `7F`
to map them back to ASCII, and outputs an `SO` control to activate the
soft font in the conpty client.
## Validation Steps Performed
I've manually tested with a number of soft fonts and applications that
make use of soft fonts. But if you're testing with the VT320 fonts from
the vt100.net collection, note that you'll need to enable the ISO-2022
coding system first, since they use 8-bit C1 controls.
When we added support for the `DECAC1` control sequence, which
determines whether `C1` controls are accepted or not, the intention was
that conhost would be making that determination, and Windows Terminal
would always be expected to accept any passed-through `C1` controls.
However, this didn't take into account that a passed-through `RIS`
sequence could end up disabling `DECAC1`, and that would leave Windows
Terminal incapable of processing any `C1` controls. This PR attempts to
fix that oversight.
The `DECAC1` sequence was added in PR #11690, when we disabled `C1`
acceptance by default.
This is a bit of a hack, but I've added a new `AlwaysAcceptC1` mode to
the state machine, which is enabled at startup in the Terminal, and is
never disabled. The parser then just needs to check whether either
`AcceptC1` or `AlwaysAcceptC1` are set.
## Validation Steps Performed
I've manually confirmed the test case in #13968 now works as expected.
Closes#13968
This PR introduces a mechanism for passing through line rendition
attributes to the conpty client, so we can support double-width and
double-height text in Windows Terminal.
Line renditions were first implemented in conhost (with the GDI
renderer) in PR #8664, and were implemented in the DX renderer in PR
#13102.
By default this won't add any additional overhead to the conpty output,
but as soon as there is any usage of double-size text, we switch to a
mode in which every line output will be prefixed with a line rendition
sequence. This is to ensure that the line attributes in the client
terminal are always in sync with the host.
Since this does add some overhead to the conpty output, we'd prefer not
to remain in this mode longer than necessary. So whenever there is a
full repaint of the entire viewport, we check to see if all of the lines
are single-width. If that is the case, we can then safely skip the line
rendition sequences in future updates.
One other small optimization is when the conpty update is only writing
out a single character (this is something we already check for). When
that is the case, we can safely skip the line rendition prefix, because
a single character update should never include a change of the line
rendition.
## Validation Steps Performed
I've manually tested that Windows Terminal now passes the double-size
tests in _Vttest_, and also confirmed various edge cases are working
correctly in my own double-size tests.
Closes#11595
Our Windows branch name changed, and I took this opportunity to resolve
an issue where vpack builds would occasionally fail due to GitHub rate
limiting the Azure DevOps IP addresses.
`ATLAS_POD_OPS` doesn't check for `has_unique_object_representations` and so a
bug exists where `CachedCursorOptions` comparisons invoke undefined behavior.
The color of inactive tab text is incorrect since #13689 due to the introduction
of `til::color::layer_over` which incorrectly calculated the RGB values.

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

This PR adds support for the `DECBKM` sequence, which provides a way for
applications to specify whether the `Backspace` key should generate a
`BS` character or a `DEL` character.
On the original VT100 terminals, the `Backarrow` key generated a `BS`,
and there was a separate `Delete` key that generated `DEL`. However, on
the VT220 and later, there was only the `Backarrow` key. By default it
generated `DEL`, but from the VT320 onwards there was an option to make
it generate `BS`, and the `DECBKM` sequence provided a way to control
that behavior programmatically.
On modern terminals, the `Backspace` key serves as the equivalent of the
VT `Backarrow`, and typically generates `DEL`, while `Ctrl`+`Backspace`
generates `BS`. When `DECBKM` is enabled (for those that support it),
that behavior is reversed, i.e. `Backspace` generates `BS` and
`Ctrl`+`Backspace` generates `DEL`.
This PR also gets the other `Backspace` modifiers more closely aligned
with the expected behavior for modern terminals. The `Shift` modifier
typically has no effect, and the `Alt` modifier typically prefixes the
generated sequence with an `ESC` character.
While not strictly related to `DECBKM`, I noticed while testing that the
`_SetInputMode` method was doing unnecessary work that was specific to
the `FocusEvent` mode. I've now moved that additional processing into
the `EnableFocusEventMode` method, which I think makes things somewhat
simpler.
## Validation Steps Performed
I've tested the basic `DECBKM` functionality in Vttest, and I've
manually tested all the modifier key combinations to make sure they
match what most modern terminals generate.
I've also added a unit test that confirms that the expected sequences
are generated correctly when the `DECBKM` mode is toggled.
Closes#13884
In testing the following issues were found in AtlasEngine and fixed:
1. "Toggle terminal visual effects" action not working
2. `d2dMode` failed to work with transparent backgrounds

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

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

#13269 - Color Schemes Rejuv
## Summary of the Pull Request
As described in #9583, this change implements the legacy conhost "EnableColorSelection" feature.
## Detailed Description of the Pull Request / Additional comments
@zadjii-msft was super nice and provided the outline/plumbing (WinRT classes and such) as a hackathon-type project (thank you!)--a "SelectionColor" runtimeclass, a ColorSelection method on the ControlCore runtimeclass, associated plumbing through the layers; plus the action-and-args plumbing to allow hooking up a basic "ColorSelection" action, which allows you to put actions in your settings JSON like so:
```json
{
"command":
{
"action": "experimental.colorSelection",
"foreground": "#0f3"
},
"keys": "alt+4"
},
```
On top of that foundation, I added a couple of things:
* The ability to specify indexes for colors, in addition to RGB and RRGGBB colors.
- It's a bit hacky, because there are some conversions that fight against sneaking an "I'm an index" flag in the alpha channel.
* A new "matchMode" parameter on the action, allowing you to say if you want to only color the current selection ("0") or all matches ("1").
- I made it an int, because I'd like to enable at least one other "match mode" later, but it requires me/someone to fix up search.cpp to handle regex first.
- Search used an old UIA "ColorSelection" method which was previously `E_NOTIMPL`, but is now wired up. Don't know what/if anything else uses this.
* An uber-toggle setting, "EnableColorSelection", which allows you to set a single `bool` in your settings JSON, to light up all the keybindings you would expect from the legacy "EnableColorSelection" feature:
- alt+[0..9]: color foreground
- alt+shift+[0..9]: color foreground, all matches
- ctrl+[0..9]: color background
- ctrl+shift+[0..9]: color background, all matches
* A few of the actions cannot be properly invoked via their keybindings, due to #13124. `*!*` But they work if you do them from the command palette.
* If you have "`EnableColorSelection : true`" in your settings JSON, but then specify a different action in your JSON that uses the same key binding as a color selection keybinding, your custom one wins, which I think is the right thing.
* I fixed what I think was a bug in search.cpp, which also affected the legacy EnableColorSelection feature: due to a non-inclusive coordinate comparison, you were not allowed to color a single character; but I see no reason why that should be disallowed. Now you can make all your `X`s red if you like.
"Soft" spots:
* I was a bit surprised at some of the helpers I had to provide in textBuffer.cpp. Perhaps there are existing methods that I didn't find?
* Localization? Because there are so many (40!) actions, I went to some trouble to try to provide nice command/arg descriptions. But I don't know how localization works…

## Validation Steps Performed
Just manual testing.
This commit stores a hash of the `settings.json` file in `ApplicationState`
with which we can detect whether the settings contents actually changed.
Since I only use a small 64-bit hash as opposed to SHA2 for instance,
I'm taking the last write time of the file into account as well.
This allows us to skip calling `UpdateJumplist` at least the majority of app
launches which hopefully improves launch performance on devices with slower IO.
Part of #5907.
## Validation Steps Performed
* Delete some profiles (see above), save settings, tasks are gone ✅
FYI For some (...) inexplicable reason, shell task lists are preserved forever
even if msix applications are uninstalled, etc. So to test whether tasks are
properly written on first app launch we have to delete some profiles/tasks
first, otherwise we can't see whether they're actually written later.
* Now exit Windows Terminal, delete `settings.json` and relaunch
* All tasks are back ✅
* With a debugger, ensure that `CascadiaSettings::WriteSettingsToDisk`
generates the same hash that `LoadAll` reads. ✅
Update the color schemes page with the new Win 11 style.
With the rejuvenated experience, we now have two pages:
- `ColorSchemes.xaml`: "color scheme selection" page
- This is the starting page for the "color schemes" nav view
item. It is intended to have the user select a color scheme
they want to modify. The user can also click the "Add new"
button to add a new color scheme or the "delete" button to
delete the selected scheme.
- If a scheme cannot be deleted, the delete button is disabled
and a disclaimer is shown.
- A "set as default" button sets the selected scheme as the
color scheme for profiles.default (aka "base layer").
- The list view item for each scheme includes the name of the
scheme, the default tag (if the scheme is the one set in base
layer), a text preview of the foreground/background, and a
grid of 16 color chips showing the colors for the scheme.
- Implementation details:
- View - `ColorSchemes`:
- "Enter" --> edit the selected scheme
- "Delete" --> delete the selected scheme
- if the selected scheme cannot be deleted, we
show the disclaimer
- View model - `ColorSchemesPageViewModel`
- when possible, the XAML binds directly to the
view model functions. Thus, we include logic
to delete, edit, and set the selected scheme
as default.
- store the current page, so that we know which
page to navigate to upon saving/discarding
changes.
- `EditColorScheme.xaml`: "color scheme modification" page
- a terminal preview of the color scheme is shown at the top of
the page.
- all colors for the scheme are displayed as color chips in an
expander that starts as expanded.
- renaming a color scheme is also inside an expander, but
there's no need for "renaming mode" anymore
- Implementation details:
- View - `EditColorScheme`:
- include logic to display the disclaimer and
add the automation properties
- include logic for "Enter" and "Escape" in the
rename editor
- View Model - `ColorSchemeViewModel`:
- as before, when possible, the XAML binds
directly to the view model functions.
- To enable the "default" tag functionality, we
had to expose knowledge of being the default
via "IsDefaultScheme()" which compares the
current name to the one in the settings model.
- Miscellaneous implementation details:
- to get the expander to start as expanded, we had to modify the
setting container style.
- Since "set as default" is a button on the selector page, we
needed a way to refresh the view model's knowledge of being
the default. So we added a `RefreshIsDefault` API to the
`ColorSchemeViewModel` to notify changes.
- With the new layout, we no longer need an 'enter rename mode'
button, so all that logic has been removed
- Add logic to `MainPage` to handle navigating to the correct
page upon saving/discarding changes.

This is one of the bullet points in #13725
This commit implements support for `experimental.rendering.software`.
There's not much to it. It's just another 2 if conditions.
## Validation Steps Performed
* `"experimental.rendering.software": false` renders with D3D ✅
* `"experimental.rendering.software": true` triggers the new code path ✅
This commit implements support for custom shaders in AtlasEngine
(`experimental.retroTerminalEffect` and `experimental.pixelShaderPath`).
Setting these properties invalidates the device because that made it
the easiest to implement this less often used feature.
The retro shader was slightly rewritten so that it compiles without warnings.
Additionally we noticed that AtlasEngine works well with D3D 10.0 hardware,
so support for that was added bringing feature parity with DxRenderer.
Closes#13853
## Validation Steps Performed
* Default settings (Independent Flip) ✅
* ClearType (Independent Flip) ✅
* Retro Terminal Effect (Composed Flip) ✅
* Use wallpaper as background image (Composed Flip) ✅
* Running `color 40` draws everything red ✅
* With Retro Terminal Effect ✅
When selecting candidate history, priority is given to histories with empty commands list.
I think lazily calling `s_Allocate` will require a ton of rewriting. Also I think it is not an unexpended behavior that buffer is allocated when an application connects.
Closes#13571
## Summary of the Pull Request
Introduces a new action `expandSelectionToWord()` which expands the beginning and end of the selection to encompass the word(s) it's on. This was implemented as a conditional keybinding where the key chord is passed through to the terminal if no selection is active (similar to `copy()`).
It is not bound to anything by default.
## PR Checklist
* [x] Closes#8274
* [x] Schema updated.
## Validation Steps Performed
- Scenario in #8274:
- search for some text in the find dialog
- ESC to close the dialog
- execute `expandSelectionToWord()`
- the new selection encompasses the whole word
- mark mode
- move onto a word
- execute `expandSelectionToWord()`
- mouse selection (same as above)
- select a portion of two words --> new selection fully encompasses both words
Direct2D is able to detect remote connections and will switch to sending
draw commands across RDP instead of rendering the data on the server.
This reduces the amount of data that needs to be transmitted as well
as the CPU load of the server, if it has no GPU installed.
This commit changes `AtlasEngine` to render with just Direct2D if a software or
remote device was chosen by `D3D11CreateDevice`. Selecting the DXGI adapter the
window is on explicitly in the future would allow us to be more precise here.
This new rendering mode doesn't implement some of the more fancy features just
yet, like inverted cursors or coloring a single wide glyph in multiple colors.
It reuses most existing facilities and uses the existing tile hash map to cache
DirectWrite text layouts to improve performance. Unfortunately this does incur
a fairly high memory overhead of approximately 25MB for a 120x30 viewport.
Additional drive-by changes include:
* Treat the given font size exactly as its given without rounding
Apparently we don't really need to round the font size to whole pixels
* Stop updating the const buffer on every frame
* Support window resizing if `debugGeneralPerformance` is enabled
Closes#13079
## Validation Steps Performed
* Tested fairly exhaustively over RDP ✅
More or less, as in #13554
* Dark theme by default (was `system`)
* Justification:
> I think the interesting thing that we have today is that the color
> scheme is dark by default, but our window theme is set to system.
> System theme in Windows 11 is defaulted to light unless changed by
> the user. Now, we have a conflict between the theme and color scheme
> in Terminal.
>
> I think our options become, make the color scheme match "default"
> and set it to a light color scheme if the system theme is light, or
> manually match the theme to the color scheme by setting it to dark.

* `tab.background: terminalBackground`
* Change the tab row colors back to "what they were pre-Controlsv2" more
or less
- The ramp is based off of "Light tab row background from Edge's
unfocused titlebar color, inactive tab row color BG from the
controlsv1 colors"
* `tabRow.unfocusedBackground` set `Transparent`
Closes#13554
Does what it sounds like on the label.
This is important, because when unset, the tab will use the active `Background` color to create an inactive BG, which maybe isn't what we want. Consider:
- a bright cyan active BG,
- and `terminalBG` for the `tabRow` bg.
Without an unfocusedBackground setting, all the tabs will still appear cyan when unfocused, which is extra gross.
As a judgement call, I made `terminalBackground` and `accent` use 30% opacity when set, to match the existing coloration.
See also #13554. If we want to make the default theme `tab.background: terminalBackground`, we should make `tab.unfocusedBackground` transparent (`#00000000`) by default. Otherwise, a Campell (`#0c0c0c`) tab on _any_ tab row will still have a faint tab visible.
* closes#13684
* closes#13246
* tested manually
This also does a lot of code shuffling, to get SettingsUI tabs to behave sensibly. We want those tabs to have (`#0c0c0c`, `#ffffff`) colored BGs for `terminalBackground` (see mail thread).
We also don't want dark focused tabs colors, combined with light tab row colors, combined with transparent unfocused tabs, to result in unfocused tabs having white-on-white text. That's gross. So that's been added to this PR in b38b704.
This pull request adds the JSON schema for `cgmanifest.json`.
## FAQ
### Why?
A JSON schema helps you to ensure that your `cgmanifest.json` file is valid.
JSON schema validation is a build-in feature in most modern IDEs like Visual Studio and Visual Studio Code.
Most modern IDEs also provide code-completion for JSON schemas.
### How can I validate my `cgmanifest.json` file?
Most modern IDEs like Visual Studio and Visual Studio Code have a built-in feature to validate JSON files.
You can also use [this small script](https://github.com/JamieMagee/verify-cgmanifest) to validate your `cgmanifest.json` file.
### Why does it suggest camel case for the properties?
Component Detection is able to read camel case and pascal case properties.
However, the JSON schema doesn't have a case-insensitive mode.
We therefore suggest camel case as it's the most common format for JSON.
### Why is the diff so large?
To deserialize the `cgmanifest.json` file, we use [`JSON.parse()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse).
However, to serialize the JSON again we use [`prettier`](https://prettier.io/).
We found that, in general, it gave smaller diffs than the default [`JSON.stringify()`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify) function.
Since locking the console can take a non-trivial amount of time,
the main thread might have already released the ControlCore instance, while the
`UpdatePatternLocations` background thread is holding the last active reference.
If the function call goes out of scope, we destroy the instance, which might
not be safe, considering its members are usually only used by the main thread.
This commit fixes the issue by only holding a reference of the `Terminal`.
## Validation Steps Performed
* Patterns are recognized ✅
See https://github.com/microsoft/terminal/issues/12176#issuecomment-1199488906, and MSFT:39723014.
I have literally no idea how to repro this one, or debug it. The dump I looked at looked like there was a `SwapChainScaleChanged` that was being dispatched as the app was tearing down. The `ControlCore` had started closing, but the `TermControl` hadn't yet. Apparently, just none of the `_refreshSizeUnderLock` callers checked if we were already closing.
All the callers appear to be on the main thread.
Closes#12176
Since there's no real way for me to repro this manually, I'm thinking we fire this fix off to the OS terminal build, where we'll pretty quickly be able to see if this fixed it or not.
While having a debugger attached, opening the settings tab generates an
uncomfortable amount of exceptions. This change reduces this by a lot.
## Validation Steps Performed
* Icons still appear ✅
This PR introduces a new action for closing all unfocused / other panes within a tab.
**Edit (17-08-2022):** Read-only panes are ignored when this action is being used (i.e., left open).
## Validation Steps Performed
The action was manually tested by applying it to various 'compositions' of panes. This includes tests on read-only panes.
Closes#12216
This PR by itself doesn't _really_ change much. Technically, now the Terminal will respect the Title of a `.lnk` when started for defterm, but we don't do anything else yet. Primarily, the goal of this PR is to just wire up startup info in OpenConsole to the connected Terminal.
* This required a bit of changes in `srvinit.cpp:ConsoleEstablishHandoff` to replicate other bits of startup, where we crack open the connect message to get the relevant bits of info.
* We pack that all into a `TERMINAL_STARTUP_INFO`, which we pass along to the registered terminal application.
* `ConptyConnection` accepts the handoff, and gathers that information out of the `TERMINAL_STARTUP_INFO`
* Some other updates to the scratch sln were made to make it build again (related, but unimportant).
* This is a precursor to:
* #13111
* #12154
* Closes#9458
* Tested manually
* I work here
## Summary of the Pull Request
The command palette (and tab search by extension) doesn't ever tell screen readers what is selected. Here, we simply hook up the selection changed event to a function that tells the screen reader what is selected. With this, the user no longer has to tab into the list view to know what is selected!
Will resolve the following bug upon validation from a11y team: #12065
## Validation Steps Performed
Performed repro steps from #12065.
NOTE: we do NOT read the selected item when the command palette is first opened. I think that's ok.
I got tired of renaming the packages that came out of our build
pipeline. I also got tired of the fact that every appxbundle artifact we
upload comes with another whole copy of Terminal for every architecture,
plus all their symbols. Those are reflected in other artifacts, so
there's no reason to duplicate them.

Apparently, calling `GetText(INT_MAX)` causes a HUGE memory spike for a few seconds each time this is called. The [UIA docs](https://docs.microsoft.com/en-us/windows/win32/api/uiautomationcore/nf-uiautomationcore-itextrangeprovider-gettext#parameters) say to put `-1` if no limit is required, but I assume a few people have been hit by this before.
This addresses this issue (and similar ones) in two ways:
1. as we iterate over the lines of text, if we're already past the max length, just break out of the loop
2. _only_ resize if the max length is actually less than the current length. This prevents us padding the string with `L'\0'` erroneously (which is probably what causes the memory spike).
While debugging #13694, we discovered a very subtle bug we had accidentally introduced in a few places. `ViewModelHelper` defines a `PropertyChanged` event, backed by a `_propertyChangedHandlers` `event`. All opbservable properties in the viewmodels are supposed to run through that event. However, if you do `WINRT_CALLBACK(PropertyChanged, Windows::UI::Xaml::Data::PropertyChangedEventHandler)` in a derived class, it'll override that original method with the new one. XAML will subscribe to the second one, which is backed by `_PropertyChangedHandlers`, but the properties will still raise notifications on the callbacks registered to `_propertyChangedHandlers`.
This change makes it more explicit in these derived classes, that the `PropertyChanged` method exposed by these classes is indeed the one that's implemented in the base class.
This is a bit of a footgun, for sure. AuditMode would have apparently caught this, as we'd be overriding a method without using the `override` keyword.
Unblocks #13694.
In Global Appearance SUI, the toggle switch for "Always show tabs" is now grayed out when "Hide the title bar" is enabled (the default).
Also, the order of the settingcontainers was changed to help show the cause and effect more. See [this comment](https://github.com/microsoft/terminal/issues/12873#issuecomment-1094928881).
Closes#12873
After some deliberation I noticed that rounding the glyph advance up to yield
the cell width is at least just as wrong as rounding it. This is because
we draw glyphs centered, meaning that (at least in theory) anti-aliased
pixels might clip outside of the layout box on _both_ sides of the glyph
adding not 1 but 2 extra pixels to the glyph size. Instead of just `ceilf`
we would have had to use `ceilf(advanceWidth / 2) * 2` to account for that.
This commit simplifies our issue by just going with what other applications do:
Round all sizes (cell width and height) to the nearest pixel size.
Closes#13812
## Validation Steps Performed
* Set a breakpoint on `scaling Required == true` in `AtlasEngine::_drawGlyph`
* Test an assortment of Cascadia Mono, Consolas, MS Gothic, Lucida Console
at various font sizes (6, 7, 8, 10, 12, 24, ...)
* Ensure breakpoint isn't hit ✅
This tells us that no glyph resizing was necessary
This commit fixes two race conditions:
* `SetPseudoWindowCallback` set the `_pseudoWindowMessageCallback`
callback after the Win32 message thread was already spawned.
This issue was fixed by instead using the `ServiceLocator` to get
a hold of the global `VtIo` instance which is created statically.
* `XtermEngine::SetWindowVisibility` was called without holding the
console lock. This issue was fixed by simply acquiring it first.
Closes MSFT:40913882
## Validation Steps Performed
* Add `IsConsoleLocked()` assertion in `VtEngine::_Write`
* Run Windows Terminal
* No assertion failures ✅

In #13024, we removed `Terminal::GetCursorPosition` from TerminalCore.
This has been widely regarded as a good move.
Now, you might rightly be wondering: why didn't compilation immediately
fail? Well. It turns out that there were _two_ copies of
`GetCursorPosition`. One for `const Terminal`, and one for `Terminal`.
This is important.
`Terminal::GetCursorPosition()` returned the cursor position relative to
the viewport. `Terminal::GetCursorPosition() const`, however, returns
the cursor position in absolute.
We removed the non-`const` one. Fortunately, thanks to the lookup rules
for `const`-qualified members, this didn't matter. Code that called
`GetCursorPosition()` still called `GetCursorPosition()`, and everything
was fine.
Except that part about the relative coordinates. That was not fine.
The TSF control is the _only_ consumer of `ControlCore.CursorPosition`,
and that was the _only_ consumer of relative-`GetCursorPosition()`.
This commit restores equilibrium by introducing a new
`GetViewportRelativeCursorPosition()` member to `Terminal` and switching
over the only consumer of relative cursor position to use it.
Closes#13769.
The absolute disgrace of a fix called 65b71ff failed to account for `std::move`
being unsafe to use for overlapping ranges. While `std::move` works for trivial
types (it happens to delegate to `memmove`), we need to dynamically switch
between that and `std::move_backward` to be correct.
Without this fix the LRU refresh is incorrect and might lead to crashes.
## Validation Steps Performed
I'm working on a new, pure D2D renderer inside AtlasEngine, which uses
the iterators contained in `_r.cellGlyphMapping` to draw text.
I noticed the bug, because scrolling up caused the text to be garbled
and with this fix applied it works as expected.
Fixes MSFT:38775539
Might also fix MSFT:38614563
Looking at this code should be pretty clear what's going on. On exit, the XAML root is already nulled out. But here, we're just yolo'ing and assuming it exists (why wouldn't it). So yea. This is like weirdly high percent of crashes internally, but that's not from real users. Real users, I suspect hit this as like .3% of our crashes. Not zero, but _low_.

There's a small race here. The renderer thread in ConPTY might notice the terminal is gone, call CloseOutput, and release the vt renderer, and then the window proc fires and decides to minimize/restore the window, triggering an A/V.
I'm 100% confident that this has NEVER happened to a real user. But the test labs hit it so much that it makes up ~26% of our crashes.
I haven't tested this cause again, _it doesn't hit in the wild_

## Validation Steps Performed
This change is trivial enough that I simply opened the new redirects
in my browser, ensuring that they open the expected websites.
`debugGlyphGenerationPerformance` used to only test the performance of
text segmentation/parsing, so I renamed it to `debugTextParsingPerformance`.
The new `debugGlyphGenerationPerformance` actually clears the glyph atlas now.
Additionally this fixes a bug with `debugGeneralPerformance`:
If a `DXGI_SWAP_CHAIN_FLAG_FRAME_LATENCY_WAITABLE_OBJECT` is requested,
it needs to be used. Since `debugGeneralPerformance` is for testing without
V-Sync, we need to ensure that the waitable object is properly disabled.

We have a number of theories why #12607 is happening, one of which is that
some GPU drivers somehow rely on Win32 messages or similar which we process
on the main thread. If we then try to acquire the console lock on the main
thread, while the GPU-driver thread itself is holding that lock, we've got
ourselves a deadlock. This PR makes this less likely by running the repeat
offender `UpdatePatternLocations` on a background thread instead.
We have a number of other locations which acquire the console lock on the
main thread and a thorough bug fix must be done in a different way.

Currently "Inverse Cursor" is actually simply bitwise inversed.
It works fine, except when it does not, namely in the middle of the spectrum:
Anything close enough to dark grey (index 8, RGB(128, 128, 128) in the
classic palette) will for obvious reasons become almost the same dark grey
again after the inversion.
The issue is addressed by additionally `XOR`ing the inverted color with
RGB(63, 63, 63). This distorts the result enough to avoid collisions
in the middle. Ultimately this restores the behavior that was in
Windows Console since the Middle Ages (and still exists in ConhostV1.dll).

Adds a variable `_isBackgroundLight` that is updated when the background
color is changed. When it is `true`, the BEL indicator flash will darken
the screen instead of brightening.
`_isColorLight(bg)` returns `true` if the average of `r`, `g`, and `b`
is >127
I was unsure of an appropriate way to change the color of the
`CompositionLight` based on the background, so I changed it to always be
gray and adjusted the intensity values of the original animation to have
roughly the same visual effect as the white.
## Validation Steps Performed
* Tested the two flashes on the default color schemes and some custom
background colors to see if they look consistent
* Used tracepoints and visual to check that the right animation is used
(including multiple tabs, split windows with different themes, and
changing settings while window is open)

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.

wyhash was chosen based on the results found in `smhasher`, were it proved
itself as an algorithm with little flaws and fairly high output quality.
While I have a personal preference for xxhash (XXH3 specifically), wyhash is a
better fit for this project as its source code is multiple magnitudes smaller,
simplifying the review and integration into the header-only `hash.h` file.
For use with hashmaps the hash quality doesn't actually matter much for
optimal performance and instead the binary size usually matters more.
But even in that scenario wyhash is fairly close to FNV1a (aka "FNV64").
The result is that this new hash algorithm will only have little impact on
hashmap performance if used over the standard FNV1a as used in the STL,
while simultaneously offering a vastly better hash quality.
This partially solves #13124.
## Validation Steps Performed
* Added test cases ✅
Other settings model classes call `JsonUtils::SetValueForKey` with the
private `_##value` member as the value. Since `_##value` is an optional,
this prevented writing out unset, optional fields. The new `Themes` class
deviated from this and this commit brings it back in line with the others.
Closes#13544
## Validation Steps Performed
* Create a `{ "name": "test" }` theme
* Save settings via the UI

While working on #13398 I felt that `TSFInputControl` wasn't up to sniff.
This commit is a minor cleanup of the class:
* default member initializers
* Simplified use of STL classes which already perform boundary checks
* Correctly check text buffer emptiness in `_SendAndClearText`
* Track selection range as mandated by the API

## Summary of the Pull Request
- We only ever have 1 color picker now, instead of each tab having its own
- `TerminalPage` constructs this color picker (upon first request for it)
- `TerminalPage` attaches the color picker to the tab that requested for it
- `TerminalTab` detaches the color picker when it is done with it, so that `TerminalPage` can attach it to another tab later on

## Summary of the Pull Request
In general, when a selection marker is shown, we should scroll to it. The `selectAll` action adds a selection marker, but we don't scroll to it. This PR makes it such that we do do that.
Epic: #4993Closes#13485
Updates the schema such that the scroll mark settings are defined as profile settings instead of global settings (because they're actually profile settings).
Separately (but still relevant), I've also updated the release notes.
Closes#13583
This fixes an issue were overwriting parts of a row would only trigger
that specific portion of the row to be redrawn. This isn't just
problematic for combining characters, but also for things like
the new `TestDbcsBisectWriteCells` test introduced in #13626.
Benchmarks showed no impact on performance whatsoever.
## Validation Steps Performed
* Pick this commit into #13626
* Run the `TestDbcsBisectWriteCells` test and break before OpenConsole exits
* A correct "QいかなZYXWVUTに" output is visible ✅
This commit makes AtlasEngine recognize Powerline glyphs as box drawing ones.
The extra pixel offsets when determining the `scale` caused weird artifacts
and thus were removed. It seems like this causes no noticeable regressions.
Closes#13029
## Validation Steps Performed
* Run all values of `wchar_t` through `isInInversionList`
and ensure it produces the expected value ✅
* Powerline glyphs are correctly scaled with Cascadia Code PL ✅
07d58a8 contains a regression where the settings' `Themes()` property is
accessed without checking whether it's a `nullptr`. This can happen because
the invalid settings modal is shown with a empty settings model object.
This commit fixes the issue by deferring the update of `_settings` until
after we ensured that the `_settings` object is valid (besides warnings).
Closes#13543
## Validation Steps Performed
* Replace any string value with `123`
* Application doesn't crash ✅
## Summary of the Pull Request
- When 'discard changes' is hit, we re-initialize our list of color scheme view models but forgot to tell xaml about it, this commit fixes that.

## Summary of the Pull Request
Adds a new mode to `CloseOnExit`: `Automatic`. In this mode, if a process handed off by defterm terminates for whatever reason, we always close (i.e. we treat the mode as `Always`), but for processes launched by Terminal we terminate as with the `Graceful` behaviour.

## Detailed Description of the Pull Request / Additional comments
- Adds a new enum value to `CloseOnExit`
- Adds a new function to `Pane`: `FinalizeConfigurationGivenDefault`: this is a function that should be called when the pane is created via default terminal handoff, and can contain any special configurations we should set given that the pane was created via handoff
## Validation Steps Performed
Curiously, at least on Windows 10 (and rarely on Windows 11), if you minimize the Terminal by clicking on the taskbar, then alt-tab to try and restore the window, the Taskbar will decide to call `SwitchToWindow` on the invisible, owned ConPTY window instead of the main window. When that happens, ConPTY'll get a `WM_SIZE(SIZE_RESTORED, lParam=0)`. The main window will NOT get a `SwitchToWindow` called. If ConPTY doesn't actually inform the hosting process about this, then the main HWND might stay hidden.
* Refer to #13158 where we disabled this.
* Closes#13589
* Closes#13248
* Tested manually on a Windows 10 VM.
* Confirmed that opening tabs while maximized/snapped doesn't restore down.
* `[Native]::ShowWindow([Native]::GetConsoleWindow(), 6)` still works
## Summary of the Pull Request
Adds support for the `tab.showCloseButton` property to themes. This accepts three values:
* `"always"` (default): The close button acts like it does today.
* `"hover"`: The close button is always visible on the active tab. On inactive tabs, the close button only appears on mouse over.
* `"never"`: The close button is never visible. You can't close the tab with middle-click, but you can still use keyboard shortcuts to close the tab.

See the following two properties in WInUI that we're leveraging here.
* [`TabViewCloseButtonOverlayMode.OnPointerOver`](https://docs.microsoft.com/en-us/windows/winui/api/microsoft.ui.xaml.controls.tabviewclosebuttonoverlaymode?view=winui-2.7&viewFallbackFrom=winui-2.2)

One is a tabview-level property, the other is a per-tab-item property, hence why this code is a little wacky.

This commit contains 3 improvements for glyph rendering:
* Scale block element and box drawing characters to fit the cell size
"perfectly" without leaving pixel gaps between cells.
* Use `IDWriteTextLayout::GetOverhangMetrics` to determine whether glyphs
are outside the given layout box and if they are, offset their position
to fit them back in. If that still fails to fit, we downscale them.
* Always scale up glyphs that are more than 2 cells wide
This ensures that long ligatures that mimic box drawing characters like
"===" under Cascadia Code are upscaled just like regular box drawings.
Unfortunately this results in ligature-heavy text (like Myanmar) to get an
"uneven" appearance because some ligatures can suddenly appear too large.
It's difficult to come up with a good heuristic here.
Closes#12512
## Validation Steps Performed
* Print UTF-8-demo.txt
* Block characters don't leave gaps ✅
* Print a lorem-ipsum in Myanmar
* Glyphs aren't cut off anymore ✅
* Print a long "===" ligature under Cascadia Code
* The ligature is as wide as the number of cells used ✅

Introduces:
- `ColorSchemesPageViewModel`: The view model responsible for the entire color schemes page. Handles what the current scheme is, adding/deleting/renaming schemes
- `ColorSchemeViewModel`: A view model class for individual color schemes

This is an experiment, as discussed in https://github.com/microsoft/terminal/issues/11790#issuecomment-1179143049. We don't know what for sure causes these crashes, but it seems that blindly throwing, so that it gets picked up by Watson, is probably not the move. Instead, we're just gonna do our fallback, REGARDLESS of what the exception was.
See #11790, MSFT:38542548, MSFT:38572983, MSFT:38542574 et. al.
Refer to https://docs.microsoft.com/en-us/windows/win32/rstmgr/guidelines-for-applications
The OS will send us a WM_QUERYENDSESSION when it's preparing an
update for our app. It will then send us a WM_ENDSESSION, which gives
us a small timeout (~30s) to actually shut down gracefully. After
that timeout, it will send us a WM_CLOSE. If we still don't close
after the WM_CLOSE, it'll force-kill us (causing a crash which will be
bucketed to moapphang).
We will manually start a quit, so that we can persist the state. If we refuse to
gracefully shut down, the OS will crash us to focefully terminate us. We
choose to quit here, rather than just close, to skip over any warning dialogs
(e.g. "Are you sure you want to close all tabs?") which might prevent a WM_CLOSE
from cleanly closing the window.
This will cause a appHost._RequestQuitAll, which will notify the
monarch to collect up all the window state and save it.
This "crash" caused by the OS force killing us constitutes 80% of all our crashes. 80%. See MSFT:38947155, MSFT:38877540, MSFT:21058878, MSFT:31710054, MSFT:39764652, MSFT:26883776.
Closes#13569
It also fixes the issue where if you've got Terminal Dev running (outside VS), and you try to Deploy, you have to make sure to close the "Are you sure you want to close all tabs" dialog before the deployment can proceed. A deploy in VS sends the same sequence of messages as a real update.
This commit implements the remaining 5 of 8 grid lines:
left/top/right/bottom (COMMON_LVB) borders and double underline
`AtlasEngine::_resolveFontMetrics` was partially refactored to use `float`s
instead of `double`s, because that's what the remaining code uses as well.
It also helps the new, slightly more complex double underline calculation.
## Validation Steps Performed
* Print characters with the `COMMON_LVB_GRID_HORIZONTAL`, `GRID_LVERTICAL`,
`GRID_RVERTICAL` and `UNDERSCORE` attributes via `WriteConsoleOutputW`
* All 4 grid lines are visible ✅
* Grid lines correctly scale according to the `lineWidth` ✅
* Print a double underline with `printf "\033[21mtest\033[0m"`
* A double underline is fully visible ✅
Cleans up a couple local test failures.
* [x] Closes#13474: So, I clearly hadn't ran the local tests at the end of the themes PR. We needed a sensible fallback to SOME theme, even if there wasn't one provided in the user json. This is only really hit in the tests (that don't also include `defaults.json`.
* [x] Closes#13323: Meh, the ordering of the keys in this test doesn't matter. Ordering is a map implementation detail. This is fine.
* [x] Ran tests locally
We recently figured that we can drop support for Windows 7. Coincidentally
AtlasEngine never actually supported Windows 7 properly, because it called
`ResizeBuffers` with `DXGI_SWAP_CHAIN_FLAG_FRAME_LATENCY_WAITABLE_OBJECT`
no matter whether the swap chain was created with it enabled.
The new minimally supported version is Windows 8.1.
66f4f9d had another bug: Just like how we scroll our viewport by `memmove`ing
the `_r.cells` array, we also have to `memmove` the new `_r.cellGlyphMapping`.
Without this fix drawing lots of glyphs while only scrolling slightly
(= not invalidating the entire viewport), would erroneously call
`makeNewest` on glyphs now outside of the viewport. This would cause
actually visible glyphs to be recycled and overwritten by new ones.
## Validation Steps Performed
* Switch to Cascadia Code
* Print some text that fills the glyph atlas
* Scroll down by a few rows
* Write a long "==========" ligature (this quickly fills up
any remaining space in the atlas and exacerbates the issue)
* Unrelated rows don't get corrupted ✅
While working on another PR related to this I noticed that my VS
generates `.vcxproj` files that are a bit different to the ones we have.
This commit is a quick search & replace of all our project files to make
(primarily) their `ToolsVersion` more in line with what VS does itself:
No `ToolsVersion` for `.vcxproj`, `ToolsVersion="15.0"`
for `.csproj` and `ToolsVersion="4.0"` for `.filters` files.
## Summary of the Pull Request
The xaml file no longer directly accesses the settings model object, and the settings model object is no longer exposed on the view model

This change adds support for the `IntenseIsBold` rendering setting.
Windows Terminal for instance defaults to `false` here, causing
intense colors to only be bright but not bold.
## Validation Steps Performed
* Set "Intense text style" to "Bright colors"

* "test" appears as bright without being bold ✅
## Summary of the Pull Request
This is a spec specifically dedicated to Mark Mode. It's an addition to the Keyboard Selection spec. I felt that it makes the most sense to make this a separate PR because there's a lot of ideas that are very specific to Mark Mode, and this gives us the space to modify some of that behavior and get a good look at how other terminal emulators designed this feature.

## PR Checklist
* [X] Contributes to #715
#8000 will change the way we store text from a strict grid/matrix where
one UTF16 character or surrogate pair always equals 1 column with the
possibility of joining exactly 2 to a wide character pair, to a dynamic
buffer where 1 or more characters can form 1 or more columns in any
arbitrary combination. Our long term goal is to properly support both
complex grapheme clusters like Emojis and complex ligatures that a wider
than 2 columns. This change requires us to break our API as
`ReadConsoleOutputA/W` assumes the existence of exactly this grid/matrix
storage. Since we store wide characters like "い" as a single codepoint
that is simply marked as being 2 columns wide in the future, we cannot
reconstruct trailing DBCS characters that were written to the buffer
like we used to. On the other hand this new behavior allows us to
implement better Unicode support and most likely significantly improve
our performance.
### Minor breaking changes
* `ReadConsoleOutputA` will now always **zero** the high byte in
`(CHAR_INFO).Char.UnicodeChar`. Only the `.AsciiChar` can be used
then. This prevents users from storing "additional" data in the
terminal buffer.
* `ReadConsoleOutputA` will now **zero** the `.AsciiChar` if it fails to
convert the Unicode character into an appropriate DBCS.
* Example: It's possible to write "い" into a narrow column despite
being a wide character. In these cases `WriteConsoleOutputA` will
now return `0x00` instead of `0x44` (the lower half of い's code
point `0x3044`).
### Major breaking changes
* `ReadConsoleOutputW` will now repeat the leading Unicode character
twice and ignore the trailing one.
* Example 1: Writing the pair `0x3044 0xabcd` with
`WriteConsoleOutputW` used to yield the same `0x3044 0xabcd` if read
back with `ReadConsoleOutputW`. This worked because conhost
effectively ignored the trailing codepoint, allowing one to
"smuggle" data. In the future this trailing character will be
discarded and produce `0x3044 0x3044` instead.
* Example 2: Writing い with `WriteConsoleOutputA` can be done with
code page 932 (Shift-JIS) and the DBCS `0x82 0xa2`. If read back
with `ReadConsoleOutputW` this would previously yield the two
Unicode characters `0x3044 0xffff`. After this commit it'll yield
`0x3044 0x3044`.
### Alternative approaches
It's possible to "tag"/"mark" written data as originating from
`WriteConsoleOutputA/W` so that it can be reconstructed accurately later
on. However this lead to implementation complexities that we're actively
trying to avoid in the new buffer implementation. Effectively
_everything_ that touches the buffer's text would have to handle these
marks and either write or clear them. Given the most likely small amount
of users who depend on the current quirky behavior, it'd be an
unwarranted maintenance and performance burden and prevent Windows
Terminal to ever truly migrate to full Unicode support.
## Validation Steps Performed
* Adjusted feature tests complete successfully ✅
On occasion, when we submit to the store we get a package rejection
because the app name has changed for the `qps-*` locales. Instead of
constantly reserving new pseudolocalized app names every time the
pseudolocalization seed changes, we should just lock our app name so
that it does not get pseudolocalized.
Upgrade check-spelling to [v0.0.20](https://github.com/check-spelling/check-spelling/releases/tag/v0.0.20)
This upgrade includes a refresh of the workflow
key new features:
* the previous comment is collapsed
* duplicate words are flagged (see `alone` and `the`)
* forbidding patterns (see `nonexistent`, `preexisting`, and `greater than`)
Each of these features can be tuned
- comment collapsing is controlled by the `followup` bits in the workflow-- but I can't imagine why one would want to turn it off
- duplicate words can be masked in `patterns.txt` (see `Guid` and `that`)
- forbidding patterns (especially duplicates) is in `.github/actions/spelling/line_forbidden.patterns`
Fwiw, I'm slowly moving towards not using `.txt` in filenames, but it's a long term project and I have a bunch of other goals for the near term.
The refresh of advice is of course flexible -- I'm still evolving my default text. Note that the default now includes some `curl` and I'm still working on how I want to consume the output. I'm getting close to the point where I might be able to provide a tool that could reliably consume the output (including on Windows).
This code has been used internally for a while, but I tested it for this repository here:
https://github.com/check-spelling/terminal/pull/2
## Summary of the Pull Request
`AdjustIndistinguishableColors` can now be set to:
- `Never`: Never adjust the colors
- `Indexed`: Only adjust colors that are part of the color scheme
- `Always`: Always adjust the colors

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.

(yes, the cmd version is just calling powershell to do the powershell version. Too lazy to convert the rest by hand, I'm already copying from `.vscode\tasks.json`)
Building the package from VS generates the loose layout to begin with, and then registers the loose manifest, skipping the msix stop. It's a lot faster than the commandline inner loop here, unfortunately.
### 2022 Update
The following command can be used to build the terminal package, and then deploy it.
The `bx` will build just the Terminal package, critically, populating the `CascadiaPackage.build.appxrecipe` file. Once that's been built, then the `DeployAppRecipe.exe` command can be used to deploy a loose layout in the same way that Visual Studio does.
Notably, this method of building the Terminal package can't leverage the FastUpToDate check in Visual Studio, so the builds end up being considerably slower for the whole package, as cppwinrt does a lot of work before confirming that it's up to date and doing nothing.

### Accessibility
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 spec describes a new set of key bindings that allows the user to create and update a selection without the use of a mouse or stylus.
## Inspiration
ConHost allows the user to modify a selection using the keyboard. Holding `Shift` allows the user to move the second selection endpoint in accordance with the arrow keys. The selection endpoint updates by one cell per key event, allowing the user to refine the selected region.
### Creating a selection
Mark Mode is a ConHost feature that allows the user to create a selection using only the keyboard. In CMD, pressing <kbd>ctrl+m</kbd> enters mark mode. The current cursor position becomes a selection endpoint. The user can use the arrow keys to move that endpoint. While the user then holds <kbd>shift</kbd>, the selection endpoint ('start') is anchored to it's current position, and the arrow keys move the other selection endpoint ('end').
Additionally, pressing <kbd>shift+arrow</kbd> also initiates a selection, but it anchors the first selection endpoint to the cursor position.
Other terminal emulators have different approaches to this feature. iTerm2, for example, has Copy Mode (documentation [linked here](https://iterm2.com/documentation-copymode.html)). Here, <kbd>cmd+shift+c</kbd> makes the current cursor position become a selection endpoint. The arrow keys can be used to move that endpoint. However, unlike Mark Mode, a key binding <kbd>c+space</kbd> is used to change the start/stop selecting. The first time it's pressed, the 'start' endpoint is anchored. The second time it's pressed, the 'end' endpoint is set. After this, you can still move a cursor, but the selection persists until a new selection is created (either by pressing the key binding again, or using the mouse).
Though tmux is not a terminal emulator, it does also have Copy Mode that behaves fairly similarly to that of iTerm2's.
## Solution Design
The fundamental solution design for keyboard selection is that the responsibilities between the Terminal Control and Terminal Core must be very distinct. The Terminal Control is responsible for handling user interaction and directing the Terminal Core to update the selection. The Terminal Core will need to update the selection according to the direction of the Terminal Control. Terminal Core maintains the state of the selection.
Relatively recently, TerminalControl was split into `TerminalControl`, `ControlInteractivity`, and `ControlCore`. Changes made to `ControlInteractivity`, `ControlCore`, and below propagate functionality to all consumers, meaning that the WPF terminal would benefit from these changes with no additional work required.
### Fundamental Terminal Control Changes
`ControlCore::TrySendKeyEvent()` is responsible for handling the key events after key bindings are dealt with in `TermControl`. At the time of writing this spec, there are 2 cases handled in this order:
- Clear the selection (except in a few key scenarios)
- Send Key Event
The first branch will be updated to _modify_ the selection instead of usually _clearing_ it. This will happen by converting the key event into parameters to forward to `TerminalCore`, which then updates the selection appropriately.
#### Abandoned Idea: Make keyboard selection a collection of standard keybindings
One idea is to introduce an `updateSelection` action that conditionally works if a selection is active (similar to the `copy` action). For these key bindings, if there is no selection, the key events are forwarded to the application.
Thanks to Keybinding Args, there would only be 1 new command:
| Action | Keybinding Args | Description |
|--|--|--|
| `updateSelection` | | If a selection exists, moves the last selection endpoint. |
| | `Enum direction { up, down, left, right }` | The direction the selection will be moved in. |
| | `Enum mode { char, word, view, buffer }` | The context for which to move the selection endpoint to. (defaults to `char`) |
By default, the following keybindings will be set:
These are in accordance with ConHost's keyboard selection model.
This idea was abandoned due to several reasons:
1. Keyboard selection should be a standard way to interact with a terminal across all consumers (i.e. WPF control, etc.)
2. There isn't really another set of key bindings that makes sense for this. We already hard-coded <kbd>ESC</kbd> as a way to clear the selection. This is just an extension of that.
3. Adding 12 conditionally effective key bindings takes the spot of 12 potential non-conditional key bindings. It would be nice if a different key binding could be set when the selection is not active, but that makes the settings design much more complicated.
4. 12 new items in the command palette is also pretty excessive.
5. If proven wrong when this is in WT Preview, we can revisit this and make them customizable then. It's better to add the ability to customize it later than take it away.
#### Abandoned Idea: Make keyboard selection a simulation of mouse selection
It may seem that some effort can be saved by making the keyboard selection act as a simulation of mouse selection. There is a union of mouse and keyboard activity that can be represented in a single set of selection motion interfaces that are commanded by the TermControl's Mouse/Keyboard handler and adapted into appropriate motions in the Terminal Core.
However, the mouse handler operates by translating a pixel coordinate on the screen to a text buffer coordinate. This would have to be rewritten and the approach was deemed unworthy.
### Fundamental Terminal Core Changes
The Terminal Core will need to expose a `UpdateSelection()` function that is called by the keybinding handler. The following parameters will need to be passed in:
-`enum SelectionDirection`: the direction that the selection endpoint will attempt to move to. Possible values include `Up`, `Down`, `Left`, and `Right`.
-`enum SelectionExpansion`: the selection expansion mode that the selection endpoint will adhere to. Possible values include `Char`, `Word`, `View`, `Buffer`.
#### Moving by Cell
For `SelectionExpansion = Char`, the selection endpoint will be updated according to the buffer's output pattern. For **horizontal movements**, the selection endpoint will attempt to move left or right. If a viewport boundary is hit, the endpoint will wrap appropriately (i.e.: hitting the left boundary moves it to the last cell of the line above it).
For **vertical movements**, the selection endpoint will attempt to move up or down. If a **viewport boundary** is hit and there is a scroll buffer, the endpoint will move and scroll accordingly by a line.
If a **buffer boundary** is hit, the endpoint will not move. In this case, however, the event will still be considered handled.
**NOTE**: An important thing to handle properly in all cases is wide glyphs. The user should not be allowed to select a portion of a wide glyph; it should be all or none of it. When calling `_ExpandWideGlyphSelection` functions, the result must be saved to the endpoint.
#### Moving by Word
For `SelectionExpansion = Word`, the selection endpoint will also be updated according to the buffer's output pattern, as above. However, the selection will be updated in accordance with "chunk selection" (performing a double-click and dragging the mouse to expand the selection). For **horizontal movements**, the selection endpoint will be updated according to the `_ExpandDoubleClickSelection` functions. The result must be saved to the endpoint. As before, if a boundary is hit, the endpoint will wrap appropriately. See [Future Considerations](#FutureConsiderations) for how this will interact with line wrapping.
For **vertical movements**, the movement is a little more complicated than before. The selection will still respond to buffer and viewport boundaries as before. If the user is trying to move up, the selection endpoint will attempt to move up by one line, then selection will be expanded leftwards. Alternatively, if the user is trying to move down, the selection endpoint will attempt to move down by one line, then the selection will be expanded rightwards.
#### Moving by Viewport
For `SelectionExpansion = View`, the selection endpoint will be updated according to the viewport's height. Horizontal movements will be updated according to the viewport's width, thus resulting in the endpoint being moved to the left/right boundary of the viewport.
#### Moving by Buffer
For `SelectionExpansion = Buffer`, the selection endpoint will be moved to the beginning or end of all the text within the buffer. If moving up or left, set the position to 0,0 (the origin of the buffer). If moving down or right, set the position to the last character in the buffer.
**NOTE**: In all cases, horizontal movements attempting to move past the left/right viewport boundaries result in a wrap. Vertical movements attempting to move past the top/bottom viewport boundaries will scroll such that the selection is at the edge of the screen. Vertical movements attempting to move past the top/bottom buffer boundaries will be clamped to be within buffer boundaries.
**NOTE**: If `copyOnSelect` is enabled, we need to make sure we **DO NOT** update the clipboard on every change in selection. The user must explicitly choose to copy the selected text from the buffer.
### Mark Mode
Mark Mode is a mode where the user can create and modify a selection using only the keyboard.
When no selection is present, the user may use the `markMode` action to enter mark mode. Upon doing so, a selection will be created at the current cursor position.
When in mark mode, the user may...
- press <kbd>ESC</kbd> to clear the selection and exit mark mode
- invoke the `markMode` action to exit mark mode
- invoke the `copy` action (this includes right-clicking the terminal) to copy the selected text, clear the selection, and exit mark mode
- move the cursor in the following ways:
- arrow keys --> move by character
- ctrl + left/right --> move by word
- ctrl + home/end --> move to the beginning/end of the buffer
- home/end --> move to the beginning/end of the line respectively
- pgup/pgdn --> move up/down by viewport respectively
- expand the selection in the following ways:
- shift + arrow keys --> move the "end" endpoint by character
- ctrl + shift + left/right --> move the "end" endpoint by word
- ctrl + shift + home/end --> move the "end" endpoint to the beginning/end of the buffer
- shift + home/end --> move the "end" endpoint to the beginning/end of the line respectively
- shift + pgup/pgdn --> move the "end" endpoint up/down by viewport respectively
As with mouse selections, keybindings are still respected and pressing a key that is not bound to a keybinding (or mentioned above) will clear the selection and exit mark mode.
#### Corner cases
- In mark mode, if a selection was created via the keyboard, moving the cursor moves at the "end" endpoint. This is consistent with conhost.
- If a user creates a selection using the mouse, then enters mark mode, mark mode inherits the existing selection as if it was made using the keyboard.
- If `copyOnSelect` is enabled, the selection is copied when the selection operation is "complete". Thus, the selection is copied when the `copy` keybinding is used or the selection is copied using the mouse.
- If `copyOnSelect` is enabled, `ESC` is interpreted as "cancelling" the selection, so nothing is copied. Keys that generate input are also interpreted as "cancelling" the selection. Only the `copy` keybinding or copying using the mouse is considered "completing" the selection operation, and copying the content to the clipboard.
**NOTE** - Related to #3884:
If the user has chosen to have selections persist after a copy operation, the selection created by Copy Mode is treated no differently than one created with the mouse. The selection will persist after a copy operation. However, if the user exits Copy Mode in any of the other situations, the selection is cleared.
#### Block Selection
A user can normally create a block selection by holding <kbd>alt</kbd> then creating a selection.
If the user is in Mark Mode, and desires to make a block selection, they can use the `toggleBlockSelection()` action. `toggleBlockSelection()` takes an existing selection, and transforms it into a block selection (or vice-versa).
All selections created in Mark Mode will have block selection disabled by default.
#### Rendering during Copy Mode
Since we are just moving the selection endpoints, rendering the selection rects should operate normally. We need to ensure that we still scroll when we move a selection point past the top/bottom of the viewport.
In ConHost, output would be paused when a selection was present. Windows Terminal does not pause the output when a selection is present, however, it does not scroll to the new output.
#### Interaction with Mouse Selection
If a selection exists, the user is basically already in Copy Mode. The user should be modifying the "end" endpoint of the selection when using the `updateSelection()` bindings. The existing selection should not be cleared (contrary to prior behavior). However, the half-y-beam will not be drawn. Once the user presses the `copyMode` or `moveSelectionPoint` keybinding, the half-y-beam is drawn on the targeted endpoint (which will then be "start").
During Copy Mode, if the user attempts to create a selection using the mouse, any existing selections are cleared and the mouse creates a selection normally. However, contrary to prior behavior, the user will still be in Copy Mode. The target endpoint being modified in Copy Mode, however, will be the "end" endpoint of the selection, instead of the cursor (as explained earlier in the flowchart).
#### Abandoned Idea: Copy Mode
Copy Mode is a more complex version of Mark Mode that is intended to provide a built-in way to switch the active selection endpoint. This idea was abandoned because we would then run into a user education issue. Rather than reinventing the wheel, selection should feel natural like that of a text editor, and any diversion from that model should be introduced separately (i.e. keybindings). Doing so ensures that users can "hit the ground running" when trying to make a selection, but won't be hindered by new functionality that is available.
Copy Mode is a mode where the user can create and modify a selection using only the keyboard. The following flowchart covers how the new `copymode()` action works:
**NOTE**: `copyMode()` refers to the action, whereas `updateSelection()` refers to the underlying function that is being called in the code.
If a selection is not active, a "start" and "end" selection point is created at the cursor position. `updateSelection()` calls then move "start" and "end" together as one position.
Invoking `copyMode()` again, will then anchor "start" (meaning that it will be kept in place). Subsequent `updateSelection()` calls move the "end" selection point.
Invoking `copyMode()` essentially cycles between which selection point is targeted.
## UI/UX Design
### Key Bindings
| Action | Keybinding Args | Description |
|--|--|--|
| `selectAll` | none | Select the entire text buffer. |
| `markMode` | none | Toggle mark mode. If no selection exists, create a selection at the cursor position. Otherwise, use the existing selection as one in mark mode. |
| `toggleBlockSelection` | none | Transform the existing selection between a block selection and a line selection. |
| `switchSelectionEndpoint` | none | If a selection is present, switch which selection endpoint is targeted when in mark mode or another keyboard selection mode (i.e. modified a mouse selection using the keyboard). |
By default, the following key binding will be set:
```JS
{"command":"selectAll","keys":"ctrl+shift+a"},
// Copy Mode
{"command":"copyMode","keys":"ctrl+shift+m"},
{"command":"toggleBlockSelection"},
{"command":"switchSelectionEndpoint"},
```
### Selection Markers
A y-beam will be used to identify which selection endpoint is currently being moved when in mark mode. The y-beam will match the cursor color and the font size so that it essentially fills a cell in the buffer.
When we're moving the cursor (this happens when mark mode is entered from no existing selection), a full y-beam will be displayed at the cursor position.
When <kbd>shift</kbd> is held, we're expanding the selection. In this case, the y-beam will be split, and the relevant half will be rendered on the active endpoint functioning as a selection marker.
If the selection is up against the end (or beginning) of the line, the selection marker can't be rendered normally because there is no space to render it off the side of the terminal. Instead, the selection marker will be horizontally flipped. Alternatively, it can be rendered on the next available cell (i.e. end of line translates to the beginning of the next line), but that would cause issues when the selection is positioned at the beginning or end of the buffer, thus the idea was abandoned.
If the active endpoint crosses the inactive endpoint, the selection marker will be flipped. In a sense, the flag will always point away from the selection.
The y-beam doesn't make as much sense for block selections, so instead an L-shaped marker will be placed hugging the corner of the active selection endpoint.
**NOTE:** Both half y-beams could have been presented as shown in the image below. This idea was omitted because then there is no indication for which half y-beam is currently focused.
When mark mode is enabled, the cursor will stop blinking.
## Capabilities
### Accessibility
Using the keyboard is generally a more accessible experience than using the mouse. Being able to modify a selection by using the keyboard is a good first step towards making selecting text more accessible.
We will be expected to send "selection changed" events via UIA every time the cursor moves or selection updates (both are considered the same event).
### Security

### Reliability
With regards to the Terminal Core, the newly introduced code should rely on already existing and tested code. Thus no crash-related bugs are expected.
With regards to Terminal Control and the settings model, crash-related bugs are not expected. However, ensuring that the selection is updated and cleared in general use-case scenarios must be ensured.
### Compatibility

## Potential Issues
### Grapheme Clusters
When grapheme cluster support is inevitably added to the Text Buffer, moving by "cell" is expected to move by "character" or "cluster". This is similar to how wide glyphs are handled today. Either all of it is selected, or none of it.
### Circling the buffer
As usual, if the buffer is circling, the selection should be updated to follow the content (and "scroll up" appropriately).
In the event that one endpoint "scrolls" off the buffer, we must clamp "start" to the buffer origin. Conversely, in the event that both endpoints "scroll" off the buffer, the selection must be considered cleared.
## Future considerations
### Word Selection Wrap
At the time of writing this spec, expanding or moving by word is interrupted by the beginning or end of the line, regardless of the wrap flag being set. In the future, selection and the accessibility models will respect the wrap flag on the text buffer.
This spec describes a new set of non-configurable keybindings that allows the user to update a selection without the use of a mouse or stylus.
## Inspiration
ConHost allows the user to modify a selection using the keyboard. Holding `Shift` allows the user to move the second selection endpoint in accordance with the arrow keys. The selection endpoint updates by one cell per key event, allowing the user to refine the selected region.
Mark mode allows the user to create a selection using only the keyboard, then edit it as mentioned above.
## Solution Design
The fundamental solution design for keyboard selection is that the responsibilities between the Terminal Control and Terminal Core must be very distinct. The Terminal Control is responsible for handling user interaction and directing the Terminal Core to update the selection. The Terminal Core will need to update the selection according to the preferences of the Terminal Control.
Relatively recently, TerminalControl was split into `TerminalControl`, `ControlInteractivity`, and `ControlCore`. Changes made to `ControlInteractivity`, `ControlCore`, and below propagate functionality to all consumers, meaning that the WPF terminal would benefit from these changes with no additional work required.
### Fundamental Terminal Control Changes
`ControlCore::TrySendKeyEvent()` is responsible for handling the key events after key bindings are dealt with in `TermControl`. At the time of writing this spec, there are 2 cases handled in this order:
- Clear the selection (except in a few key scenarios)
- Send Key Event
The first branch will be updated to _modify_ the selection instead of usually _clearing_ it. This will happen by converting the key event into parameters to forward to `TerminalCore`, which then updates the selection appropriately.

Vertical movements attempting to move past the top/bottom buffer boundaries will be clamped to be within buffer boundaries.
Every combination of the `SelectionDirection` and `SelectionExpansion` will map to a keybinding. These pairings are shown below in the UI/UX Design --> Keybindings section.
**NOTE**: If `copyOnSelect` is enabled, we need to make sure we **DO NOT** update the clipboard on every change in selection. The user must explicitly choose to copy the selected text from the buffer.

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.

## What should be done to update this in the future?
1. Download the version of boost you want from boost.org.
2. Take the parts you want, but leave most of it behind since it's HUGE and will bloat the repo to take it all. At the time of this writing, we only use small_vector.hpp and its dependencies as a header-only library.
3. Validate that the license in the root of the repository didn't change and update it if so. It is sitting in a version-specific subdirectory below this readme.
If it changed dramatically, ensure that it is still compatible with our license scheme. Also update the NOTICE file in the root of our repository to declare the third-party usage.
