`KeyMapping` was introduced to break up `AppKeyBindings`. `KeyMapping`
records the keybindings from the JSON and lets you query them.
`AppKeyBindings` now just holds a `ShortcutActionDispatcher` to run
actions, and a `KeyMapping` to record/query your existing keybindings.
This refactor allows `KeyMapping` to be moved to the
TerminalSettingsModel, and `ShortcutActionDispatcher` and
`AppKeyBindings` will stay in TerminalApp.
`AppKeyBindings` had to be passed down to a terminal via
`TerminalSettings`. Since each settings object had its own
responsibility to update/create a `TerminalSettings` object, I moved all
of that logic to `TerminalSettings`. This helps with the
TerminalSettingsModel refactor, and makes the construction of
`TerminalSettings` a bit cleaner and more centralized.

Clang (10) has no trouble optimizing the COLORREF conversion operator to
a simple 32-bit load with mask (!) even though it's a series of bit
shifts across multiple struct members.
MSVC (19.24) doesn't make the same optimization decision, and it emits
three 8-bit loads and some shifting.
In any case, the optimization only applies at -O2 (clang) and above.
In this commit, we leverage the spec-legality of using unions for type
conversions and the overlap of four uint8_ts and a uint32_t to make the
conversion very obvious to both compilers.

j4james brought up some concerns about til::color's minor wastefulness
in https://github.com/microsoft/terminal/pull/7578#discussion_r487355989.
This is a clear, simple transformation that saves us a few instructions
in a relatively common case, so I'm accepting a micro-optimization even
though we don't have data showing this to be a hot spot.
Now that CascadiaSettings is a WinRT object, we need to update the error
handling a bit. Making it a WinRT object limits our errors to be
hresults. So we moved all the error handling down a layer to when we
load the settings object.
- Warnings encountered during validation are saved to `Warnings()`.
- Errors encountered during validation are saved to `GetLoadingError()`.
- Deserialization errors (mainly from JsonUtils) are saved to
`GetDeserializationErrorMessage()`.

- Render hyperlinks with a dashed underline
- Render hovered hyperlinks with a solid underline
- Show URI tooltip on hover
TermControl now has a canvas that contains a tiny border to which a
tooltip is attached. When we hover over hyperlinked text, we move the
border to the mouse location and update the tooltip content with the
URI.
Introduced a new underline type (HyperlinkUnderline), supports rendering
for it, and uses it to render hyperlinks. HyperlinkUnderline is usually
a dashed underline, but when a link is hovered, all text with the same
hyperlink ID is rendered with a solid underline.

This fixes an issue where two CPRs could end up corrupted in the input
buffer. An application that sent two CPRs back-to-back could
end up reading the first few characters of the first prepended CPR
before handing us another CPR. We would dutifully prepend it to the
buffer, causing them to overlap.
```
^[^[2;2R[1;1R
^^ ^^^^^ First CPR
^^^^^^ Second CPR
```
The end result of this corruption is that a requesting application
would receive an unbidden `R` on stdin; for vim, this would trigger
replace mode immediately on startup.
Response prepending was implemented in !997738 without much comment.
There's very little in the way of audit trail as to why we switched.
Michael believes that we wanted to make sure that applications got DSR
responses immediately. It had the unfortunate side effect of causing
subsequence CPRs across cursor moves to come out in the wrong order.
I discussed our options with him, and he suggested that we could
implement a priority queue in InputBuffer and make sure that "response"
input was dispatched to a client application before any application- or
user-generated input. This was deemed to be too much work.
We decided that DSR responses getting top billing was likely to be a
stronger guarantee than most terminals are capable of giving, and that
we should be fine if we just switch it back to append.
Thanks to @k-takata, @tekki and @brammool for the investigation on the
vim side.

This commit leverages C++/WinRT's final_release [extension point] to
pull the final destruction of ConptyConnection off onto a background
thread.
We've been seeing some deadlocks during teardown where the output thread
(holding the last owning reference to the connection) was trying to
destruct the threadpool wait while the threadpool wait was
simultaneously running its callback and waiting for the output thread to
terminate. It turns out that trying to release a threadpool wait while
it's running a callback that's blocked on you will absolutely result in
a deadlock.

This one _looks_ big, but most of it is really just propagating the
changes to the tests. In fact, you can probably save yourself some time
because the tests were about an hour of Find&Replace.
`CascadiaSettings::GetCurrentAppSettings()` was only being used in
Pane.cpp. So I ripped out the 3 lines of code and stuffed them in there.

By setting the jumplist entries to launch `WindowsTerminal.exe` out of
the package root, we've inadvertently made WindowsTerminalDev emit jump
list entries that launch the _unpackaged_ version of Terminal.
We can fix this by copying the code from the shell extension that
determines which version of the executable to launch -- wt, wtd or
WindowsTerminal -- depending on the context under which it was invoked.
Fixes#7554
Conhost expands UIA text ranges when moved. This means that degenerate
ranges become non-degenerate after movement, leading to odd behaviour
from UIA clients. This PR doesn't expand degenerate ranges, but rather
keeps them degenerate by moving `_end` to the newly-changed `_start`.
Tested in the NVDA Python console (cases with `setEndPoint` and
`compareEndPoints` described in #7342). Also ran the logic by
@michaeldcurran.
Closes#7342
Almost definitely addresses nvaccess/nvda#11288 (although I'll need to
test with my Braille display). Also fixes an issue privately reported to
me by @simon818 with copy/paste from review cursor which originally lead
me to believe the issue was with `moveEndPointByRange`.
This PR is about the behavior of DECSCUSR. This PR changes the meaning
of DECSCUSR 0 to restore the cursor style back to user default. This
differs from what VT spec says but it’s used in popular terminal
emulators like iTerm2 and VTE-based ones. See #1604.
Another change is that for parameter greater than 6, DECSCUSR should be
ignored, instead of restoring the cursor to legacy. This PR fixes it.
See #7382.
Fixes#1604.
This commit introduces Jumplist customization and an item for each
profile to the Jumplist. Selecting an entry in the jumplist will pretty
much just execute `wt.exe -p "{profile guid}"`, and so a new Terminal
will open with the selected profile.

This one was probably the easiest thus far.
The only weird thing is how we handle InitialPosition. Today, we lose a
little bit of fidelity when we convert from LaunchPosition (int) -->
Point (float) --> RECT (long). The current change converts
LaunchPosition (optional<long>) --> InitialPosition (long) --> RECT
(long).
NOTE: Though I could use LaunchPosition to go directly from TermApp to
AppHost, I decided to introduce InitialPosition because LaunchPosition
will be a part of TerminalSettingsModel soon.

Profile is now a WinRT object in the TerminalApp project.
As with ColorScheme, all of the serialization logic is not exposed via
the idl. TerminalSetingsModel will handle it when it's all moved over.
I removed the "Get" and "Set" prefixes from all of the Profile
functions. It just makes more sense to use the `GETSET_PROPERTY` macro
to do most of the work for us.
`CloseOnExitMode` is now an enum off of the Profile.idl.
`std::optional<wstring>` got converted to `hstring` (as opposed to
`IReference<hstring>`). `IReference<hstring>` is not valid to MIDL.

Previously, if `altGrAliasing` was disabled, all `Ctrl+Alt` combinations were considered to be aliases of `AltGr` including `AltGr` itself and thus considered as key and not character events. But `AltGr` should not be treated as an alias of itself of course, as that prevents one from entering `AltGr` combinations entirely.

This commit removes our local copy of clang-format 8 and replaces it
with a newly-built nuget package containing clang-format 10.
This resolves the inconsistency between our version of clang-format and
the one shipped in Visual Studio.
A couple minor format changes were either required or erroneously forced
upon us--chief among them is a redistribution of `*`s around SAL
annotations in inline class members of COM classes. Don't ask why; I
couldn't figure it out.
We had some aspirational goals for our formatting, which were left in
but commented out. Enabling them changes our format a little more than
I'm comfortable with, so I uncommented them and locked them to the
format style we've been using for the past year. We may not love it, but
our aspirations may not matter here any longer. Consistent formatting is
better than perfect formatting.
Most applications with scrollable content seem to define the "large
jump" distance as about a screenful of content. You can see this in long
pages in Settings and documents in Notepad.
We just weren't configuring ScrollBar here.

Adds support for "commandline mode" to the command palette.
This allows the user to start typing a `wt.exe` commandline directly in the command palette, to run that commandline directly in the current window. This allows the user input something like `> nt -p Ubuntu ; sp -p ssh` and open up a new tab and split it _in the current window_.

## Summary of the Pull Request
This PR splits the anchored and unanchored tab switcher into two. The anchored tab switcher is now baked into `nextTab`/`prevTab`, and the unanchored tab switcher command is just named `tabSearch`. `tabSearch` takes no arguments. To reflect this distinction, `CommandPalette.cpp` now refers to one as `TabSwitchMode` and the other as `TabSearchMode`.
I've added a global setting named `useTabSwitcher` (name up for debate) that makes the Terminal use the anchored tab switcher experience for `nextTab` and `prevTab`.
I've also given the control the ability to detect <kbd>Alt</kbd> KeyUp events and to dispatch keybinding events. By listening for keybindings, the ATS can react to `nextTab`/`prevTab` invocations for navigation in addition to listening for <kbd>tab</kbd> and the arrow keys.

Closes#6866
In #6532, we thought it would be a good idea to add "bindings" as an
overload for "keybindings", as we were no longer going to use the
keybindings array for just keybindings. We were going to add commands.
So we started secretly treating `"bindings"` the same as
`"keybindings"`.
Then, in #7175, we discussed using "actions" as the key for the list of
commands/keybindings/global actions, instead of using "bindings". We're
going to be using this array as the global list of all actions, so it
makes sense to just call it `"actions"`.
This PR renames "bindings" to "actions". Fortunately, we never
documented the "bindings" overload in the first place, so we can get
away with this safely, and preferably before we ship "bindings" for too
long.

#6989 forgot to add `togglePaneZoom` to the schema, so this does that.
WHILE I'M HERE:
* The action names in the schema and the actual source were both in _random_ order, so I sorted them alphabetically.
* I also added an unbound `togglePaneZoom` command to defaults.json, so users can use that command from the cmdpal w/o binding it manually.
## Summary of the Pull Request
Allows for creating commands that iterate over the user's color schemes. Also adds a top-level nested command to `defaults.json` that allows the user to select a color scheme (pictured above). I'm not sure there are really any other use cases that make sense, but it _really_ makes sense for this one.

_look at that gif_
This PR changes the way VT control sequences are identified and
dispatched, to be more efficient and easier to extend. Instead of
parsing the intermediate characters into a vector, and then having to
identify a sequence using both that vector and the final char, we now
use just a single `uint64_t` value as the identifier.
The way the identifier is constructed is by taking the private parameter
prefix, each of the intermediate characters, and then the final
character, and shifting them into a 64-bit integer one byte at a time,
in reverse order. For example, the `DECTLTC` control has a private
parameter prefix of `?`, one intermediate of `'`, and a final character
of `s`. The ASCII values of those characters are `0x3F`, `0x27`, and
`0x73` respectively, and reversing them gets you 0x73273F, so that would
then be the identifier for the control.
The reason for storing them in reverse order, is because sometimes we
need to look at the first intermediate to determine the operation, and
treat the rest of the sequence as a kind of sub-identifier (the
character set designation sequences are one example of this). When in
reverse order, this can easily be achieved by masking off the low byte
to get the first intermediate, and then shifting the value right by 8
bits to get a new identifier with the rest of the sequence.
With 64 bits we have enough space for a private prefix, six
intermediates, and the final char, which is way more than we should ever
need (the _DEC STD 070_ specification recommends supporting at least
three intermediates, but in practice we're unlikely to see more than
two).
With this new way of identifying controls, it should now be possible for
every action code to be unique (for the most part). So I've also used
this PR to clean up the action codes a bit, splitting the codes for the
escape sequences from the control sequences, and sorting them into
alphabetical order (which also does a reasonable job of clustering
associated controls).
## Validation Steps Performed
I think the existing unit tests should be good enough to confirm that
all sequences are still being dispatched correctly. However, I've also
manually tested a number of sequences to make sure they were still
working as expected, in particular those that used intermediates, since
they were the most affected by the dispatch code refactoring.
Since these changes also affected the input state machine, I've done
some manual testing of the conpty keyboard handling (both with and
without the new Win32 input mode enabled) to make sure the keyboard VT
sequences were processed correctly. I've also manually tested the
various VT mouse modes in Vttest to confirm that they were still working
correctly too.

## Detailed Description of the Pull Request / Additional comments
We have had two classes of tests that don't work in our usual build-machine testing environment:
1. Tests that require interactive UI automation or input injection (a.k.a. require a logged in user)
2. Tests that require the entire Windows Terminal to stand up (because our Xaml Islands dependency requires 1903 or later and the Windows Server instance for the build is based on 1809.)
The Helix testing environment solves both of these and is brought to us by our friends over in https://github.com/microsoft/microsoft-ui-xaml.
This PR takes a large portion of scripts and pipeline configuration steps from the Microsoft-UI-XAML repository and adjusts them for Terminal needs.
You can see the source of most of the files in either https://github.com/microsoft/microsoft-ui-xaml/tree/master/build/Helix or https://github.com/microsoft/microsoft-ui-xaml/tree/master/build/AzurePipelinesTemplates
Some of the modifications in the files include (but are not limited to) reasons like:
- Our test binaries are named differently than MUX's test binaries
- We don't need certain types of testing that MUX does.
- We use C++ and C# tests while MUX was using only C# tests (so the naming pattern and some of the parsing of those names is different e.g. :: separators in C++ and . separators in C#)
- Our pipeline phases work a bit differently than MUX and/or we need significantly fewer pieces to the testing matrix (like we don't test a wide variety of OS versions).
The build now runs in a few stages:
1. The usual build and run of unit tests/feature tests, packaging verification, and whatnot. This phase now also picks up and packs anything required for running tests in Helix into an artifact. (It also unifies the artifact name between the things Helix needs and the existing build outputs into the single `drop` artifact to make life a little easier.)
2. The Helix preparation build runs that picks up those artifacts, generates all the scripts required for Helix to understand the test modules/functions from our existing TAEF tests, packs it all up, and queues it on the Helix pool.
3. Helix generates a VM for our testing environment and runs all the TAEF tests that require it. The orchestrator at helix.dot.net watches over this and tracks the success/fail and progress of each module and function. The scripts from our MUX friends handle installing dependencies, making the system quiet for better reliability, detecting flaky tests and rerunning them, and coordinating all the log uploads (including for the subruns of tests that are re-run.)
4. A final build phase is run to look through the results with the Helix API and clean up the marking of tests that are flaky, link all the screenshots and console output logs into the AzDO tests panel, and other such niceities.
We are set to run Helix tests on the Feature test policy of only x64 for now.
Additionally, because the set up of the Helix VMs takes so long, we are *NOT* running these in PR trigger right now as I believe we all very much value our 15ish minute PR turnaround (and the VM takes another 15 minutes to just get going for whatever reason.) For now, they will only run as a rolling build on master after PRs are merged. We should still know when there's an issue within about an hour of something merging and multiple PRs merging fast will be done on the rolling build as a batch run (not one per).
In addition to setting up the entire Helix testing pipeline for the tests that require it, I've preserved our classic way of running unit and feature tests (that don't require an elaborate environment) directly on the build machines. But with one bonus feature... They now use some of the scripts from MUX to transform their log data and report it to AzDO so it shows up beautifully in the build report. (We used to have this before I removed the MStest/VStest wrapper for performance reasons, but now we can have reporting AND performance!) See https://dev.azure.com/ms/terminal/_build/results?buildId=101654&view=ms.vss-test-web.build-test-results-tab for an example.
I explored running all of the tests on Helix but.... the Helix setup time is long and the resources are more expensive. I felt it was better to preserve the "quick signal" by continuing to run these directly on the build machine (and skipping the more expensive/slow Helix setup if they fail.) It also works well with the split between PR builds not running Helix and the rolling build running Helix. PR builds will get a good chunk of tests for a quick turn around and the rolling build will finish the more thorough job a bit more slowly.
## Validation Steps Performed
- [x] Ran the updated pipelines with Pull Request configuration ensuring that Helix tests don't run in the usual CI
- [x] Ran with simulation of the rolling build to ensure that the tests now running in Helix will pass. All failures marked for follow on in reference issues.
This is based on (cribbed almost directly from) code written by the
inimitable @StephanTLavavej on one of our mailing lists.
This is a nice generic version of the approach used in
JsonUtils::EnumMapper and CodepointWidthDetector: a static array of
key-value pairs that we binary-search at runtime (or at compile time, as
the case may be.)
Keys are not required to be sorted, as we're taking advantage of
constexpr std::sort (VS 16.6+) to get the compiler to do it for us. How
cool is that?
static_map presents an operator[] or at much like
std::map/std::unordered_map does.
I've added some tests, but they're practically fully-solveable at compile
time so they pretty much act like `VERIFY_IS_TRUE(true)`.
- Add MENU key with "menu" "app" as key bindings.
- Updated profiles.schema.json and documentation.
## Validation Steps Performed
Ran tests locally.
Tested out the new key binding.
```{ "command": "openNewTabDropdown", "keys": "app" }```
Closes#7144
New warnings were added in VS 16.7 and `std::map::erase` is now `noexcept`.
Update our code to be compatible with the new enforcement.

Adds array support for the existing `copyFormatting` global setting.
This allows users to define which formats they would specifically like
to be copied.
A boolean value is still accepted and is translated to the following:
- `false` --> `"none"` or `[]`
- `true` --> `"all"` or `["html", "rtf"]`
This also adds `copyFormatting` as a keybinding arg for `copy`. As with
the global setting, a boolean value and array value is accepted.
CopyFormat is a WinRT enum where each accepted format is a flag.
Currently accepted formats include `html`, and `rtf`. A boolean value is
accepted and converted. `true` is a conjunction of all the formats.
`false` only includes plain text.
For the global setting, `null` is not accepted. We already have a
default value from before so no worries there.
For the keybinding arg, `null` (the default value) means that we just do
what the global arg says to do. Overall, the `copyFormatting` keybinding
arg is an override of the global setting **when using that keybinding**.
References #5212 - Spec for formatted copying
References #2690 - disable html copy
Validated behavior with every combination of values below:
- `copyFormatting` global: { `true`, `false`, `[]`, `["html"]` }
- `copyFormatting` copy arg:
{ `null`, `true`, `false`, `[]`, `[, "html"]`}

ColorScheme is now a WinRT object.
All of the JSON stuff can't be exposed via the idl. So the plan here is
that we'll have the TerminalSettingsModel project handle all of the

of the `implementation` namespace, not projected namespace.

## Summary of the Pull Request
This PR adds support for both _nested_ and _iterable_ commands in the Command palette.
* **Nested commands**: These are commands that include additional sub-commands. When the user selects on of these, the palette will update to only show the nested commands.
* **Iterable commands**: These are commands what allow the user to define only a single command, which is repeated once for every profile. (in the future, also repeated for color schemes, themes, etc.)
The above gif uses the following json:
```json
{
"name": "Split Pane...",
"commands": [
{
"iterateOn": "profiles",
"name": "Split with ${profile.name}...",
"commands": [
{ "command": { "action": "splitPane", "profile": "${profile.name}", "split": "automatic" } },
{ "command": { "action": "splitPane", "profile": "${profile.name}", "split": "vertical" } },
{ "command": { "action": "splitPane", "profile": "${profile.name}", "split": "horizontal" } }
]
}

## Detailed Description of the Pull Request / Additional comments
We've now gotta keep the original json for a command around, so that once we know what all the profiles will be, we can expand the commands that need it.
We've also got to parse commands recursively, because they might have any number of child commands.
These together made the command parsing a _lot_ more complicated, but it feels good so far.

Removes the if-statement in `UpdateTabIndices` that blocks all scenarios where you delete the second to last tab. This fixes the issue where the ATS gets confused about which item in the ListView is associated with which tab.
Closes#7278
This is a minor fix from #6989. If there's only one pane in the
Terminal, then we'd still "zoom" it and give it a border, but all the
borders would be black.
A single pane is already "zoomed", so it doesn't really make sense to
try and zoom if there's only one.
Whoops, members are zero initialized in Debug builds but most likely not
in Release builds So, this PR adds a couple of default values to
`_currentMode` and its associated XAML strings to make cmdpal/ats work
deterministically on first use. I also added a default value to
`_anchorKey` just to be safe.

## Validation Steps Performed
Added the following keybindings:
```json
{ "keys": "p", "command": { "action": "sendInput", "input": "foobar" } },
{ "keys": "q", "command": { "action": "sendInput", "input": "\u001b[A" } },
```
Ensured that when pressing <kbd>P</kbd> "foobar" is echoed to the shell and when pressing <kbd>Q</kbd> the shell history is being navigated backwards.
This commit ensures that we always furnish a new process with the
cleanest, most up-to-date environment variables we can. There is a minor
cost here in that WT will no longer pass environment variables that it
itself inherited to its child processes.
This could be considered a reasonable sacrifice. It will also remove
somebody else's TERM, TERM_PROGRAM and TERM_PROGRAM_VERSION from the
environment, which could be considered a win.
I validated that GetCurrentProcessToken returns a token we're
_technically able_ to use with this API; it is roughly equivalent to
OpenProcessToken(GetCurrentProcess) in that it returns the current
active _access token_ (which is what CreateEnvironmentBlock wants.)
There's been discussion about doing a 3-way merge between WT's
environment and the new one. This will be complicated and I'd like to
scream test the 0-way merge first ;P
Related to #1125 (but it does not close it or resolve any of the other
issues it calls out.)

This regressed around the #7163 timeframe.
We're discussing this on chat currently. It might break the intellisense
on the `#include <winrt/Microsoft.Terminal.TerminalControl.h>` line in
VS 16.7, but we're not _really_ sure? Intellisense has been notoriously
flaky for us.
I'm running 16.6.5, and it works for me. @lhecker is running 16.7 and
confirmed it worked there. If the CI build passes, then this definitely
will work for 16.7.
If you scroll up to view the scrollback, then we want the viewport to
"stay in place", as new output comes in (see #6062). This works fine up
until the buffer circles. In this case, the mutable viewport isn't
actually moving, so we never set `updatedViewport` to true.
This regressed in #6062Closes#7222
This pull request completes (and somewhat rewrites) the JsonUtils error
handling arc. Deserialization errors, no longer represented by trees of
exceptions that must be rethrown and caught, are now transformed at
catch time into a message explaining what we expected and where we
expected it.
Instead of exception trees, a deserialization failure will result in a
single type of exception with the originating JSON object from which we
can determine the contents and location of the failure.
Because most of the error message actually comes from the JSON schema
or the actual supported types, and the other jsoncpp errors are not
localized I've made the decision to **not** localize these messages.
## Summary of the Pull Request
This PR adds the Advanced Tab Switcher (ATS) to Terminal. It'll work
similarly to VSCode's tab switcher. Because this implementation rides
off a lot of the Command Palette's XAML code, it'll look just like the
Command Palette, and also have support for tab title search.

The "default profile as name" feature in 1.1 broke the loading of
default settings, as we would never get to the validation phase where
the default profile string was transformed into a guid.
I moved knowledge of the "unparsed default profile" optional to the
consumer so that we could make sure we only attempted to deserialize it
once (and only if it was present.)

This PR adds support for the ANSI _doubly underlined_ graphic rendition
attribute, which is enabled by the `SGR 21` escape sequence.
There was already an `ExtendedAttributes::DoublyUnderlined` flag in the
`TextAttribute` class, but I needed to add `SetDoublyUnderlined` and
`IsDoublyUnderlined` methods to access that flag, and update the
`SetGraphicsRendition` methods of the two dispatchers to set the
attribute on receipt of the `SGR 21` sequence. I also had to update the
existing `SGR 24` handler to reset _DoublyUnderlined_ in addition to
_Underlined_, since they share the same reset sequence.
For the rendering, I've added a new grid line type, which essentially
just draws an additional line with the same thickness as the regular
underline, but slightly below it - I found a gap of around 0.05 "em"
between the lines looked best. If there isn't enough space in the cell
for that gap, the second line will be clamped to overlap the first, so
you then just get a thicker line. If there isn't even enough space below
for a thicker line, we move the offset _above_ the first line, but just
enough to make it thicker.
The only other complication was the update of the `Xterm256Engine` in
the VT renderer. As mentioned above, the two underline attributes share
the same reset sequence, so to forward that state over conpty we require
a slightly more complicated process than with most other attributes
(similar to _Bold_ and _Faint_). We first check whether either underline
attribute needs to be turned off to send the reset sequence, and then
check individually if each of them needs to be turned back on again.
## Validation Steps Performed
For testing, I've extended the existing attribute tests in
`AdapterTest`, `VTRendererTest`, and `ScreenBufferTests`, to make sure
we're covering both the _Underlined_ and _DoublyUnderlined_ attributes.
I've also manually tested the `SGR 21` sequence in conhost and Windows
Terminal, with a variety of fonts and font sizes, to make sure the
rendering was reasonably distinguishable from a single underline.

## Detailed Description of the Pull Request / Additional comments
Technically, the action is being done by changing the settings of the current `TerminalSettings` of the `TermControl`. Frankly, it should be operating on a copy of the `TermControl`'s `IControlSettings`, then updating the control's settings, or the Control should just listen for changes to it's setting's properties, and update in real time (without a manual call to `UpdateSettings`. However, both those paths are somewhere unknowable beyond #6904, so we'll just do this for now.

Consecutive RTL GlyphRuns are drawn from the last to the first.
References
#538, #7149, all those issues asking for RTL closed as dupes.
As @miniksa suggested in a comment on #7149 -- handle the thingy on the
render side.
If we have GlyphRuns abcdEFGh, where EFG are RTL, we draw them now in
order abcdGFEh.
This has ransom-noting, because I didn't touch the font scaling at all.
This should fix the majority of RTL issues, except it *doesn't* fix
issues with colors, because those get split in the TextBuffer phase in
the renderer I think, so they show up separately by the GlyphRun phase.
## Summary of the Pull Request

## Summary of the Pull Request
Adds support for two actions, `closeOtherTabs` and `closeTabsAfter`. Both these actions accept an `index` parameter.
* `closeOtherTabs`: Close tabs other than `index`
* `closeTabsAfter`: Close tabs after `index` (This is also "Close tabs to the right")

* [ ] We should file an issue for "make the `index` param to `closeOtherTabs`, `closeTabsAfter` optional" to make them both work on the _active_ tab when there's no `index` provided
## Validation Steps Performed
* _Verified that_ closing all tabs when I have the `index`'th tab selected _works as expected_
* _Verified that_ closing all tabs when I have a tab other than the `index`'th tab selected _works as expected_
* _Verified that_ closing tabs to the right when I have the `index`'th tab selected _works as expected_
* _Verified that_ closing tabs to the right when I have a tab other than the `index`'th tab selected _works as expected_
- This one has one caveat: for whatever reason, if you run this action when the tab that's currently focused is _before_ the `index` param, then the tabs will expand to fill the entire width of the tab row, until you mouse over them. Probably has something to do with tabs not resizing down until there's a mouse exit event.
Up until #4999 we deferred all key events to the character event handler
for which `ToUnicodeEx` returned a valid character and alternatively
those who aren't a special key combination as listed in
`TerminalInput`'s implementation.
Since #4999 we started acknowledging/handling all key events no matter
whether they're actually a known key combination. Given non-ASCII inputs
the Win32 `SendInput()` method generates certain sequences that aren't
recognizable combinations though and if they're handled by the key event
handler no follow up character event is sent containing the unicode
character.
This PR adds another condition and defers all key events without scan
code (i.e. those not representable by the current keyboard layout) to
the character event handler.
I'm absolutely not certain that this PR doesn't have a negative effect
on other kinds of inputs.
Is it common for key events to not contain a scan code? I personally
haven't seen it happen before AutoHotKey/SendInput.
Before this PR is merged it'd be nice to have a good testing plan in
place in order to ensure nothing breaks.
## Validation Steps Performed
Remapped `AltGr+8` to `»` using AutoHotKey using `<^>!8::SendInput {Raw}»`.
Ensured `»` is printed if `AltGr+8` is pressed.

I found this while crawling through conhost's WindowIo. Mouse wheel
events come in in screen coordinates, unlike literally every other mouse
event.
The WPF control was doing it wrong.
This pull request fixes capture and event generation in VT mouse mode
for both conhost and terminal.
Fixes#6401.
[1/3] Terminal: clamp mouse events to the viewport, don't throw them away
gnome-terminal (at least) sends mouse events whose x/y are at the
extreme ends of the buffer when a drag starts inside the terminal and
then exits it.
We would previously discard any mouse events that exited the borders of
the viewport. Now we will keep emitting events where X/Y=0/w/h.
[2/3] conhost: clamp VT mouse to viewport, capture pointer
This is the same as (1), but for conhost. conhost wasn't already
capturing the pointer when VT mouse mode was in use. By capturing, we
ensure that events that happen outside the screen still result in events
sent to an application (like a release after a drag)
[3/3] wpf: capture the pointer when VT mouse is enabled
This is the same as (2), but for the WPF control. Clamping is handled
in TerminalCore in (1), so we didn't need to do it in WPF.
Move TerminalSettings object from TerminalSettings project
(Microsoft.Terminal.Settings) to TerminalApp project. `TerminalSettings`
specifically operates as a bridge that exposes any necessary information
to a TerminalControl.

This PR updates the rendering of the _underlined_ graphic rendition
attribute, using the style specified in the active font, instead of just
reusing the grid line at the bottom of the character cell.
* Support for drawing the correct underline effect in the grid line
renderer was added in #7107.
There was already an `ExtendedAttributes` flag defined for the
underlined state, but I needed to update the `SetUnderlined` and
`IsUnderlined` methods in the `TextAttribute` class to use that flag
now in place of the legacy `LVB_UNDERSCORE` attribute. This enables
underlines set via a VT sequence to be tracked separately from
`LVB_UNDERSCORE` grid lines set via the console API.
I then needed to update the `Renderer::s_GetGridlines` method to
activate the `GridLines::Underline` style when the `Underlined`
attribute was set. The `GridLines::Bottom` style is still triggered by
the `LVB_UNDERSCORE` attribute to produce the bottom grid line effect.
Validation
----------
Because this is a change from the existing behaviour, certain unit tests
that were expecting the `LVB_UNDERSCORE` to be toggled by `SGR 4` and
`SGR 24` have now had to be updated to check the `Underlined` flag
instead.
There were also some UI Automation tests that were checking for `SGR 4`
mapping to `LVB_UNDERSCORE` attribute, which I've now substituted with a
test of the `SGR 53` overline attribute mapping to
`LVB_GRID_HORIZONTAL`. These tests only work with legacy attributes, so
they can't access the extended underline state, and I thought a
replacement test that covered similar ground would be better than
dropping the tests altogether.
As far as the visual rendering is concerned, I've manually confirmed
that the VT underline sequences now draw the underline in the correct
position and style, while grid lines output via the console API are
still displayed in their original form.
Closes#2915
This PR adds support for the ANSI _crossed-out_ graphic rendition
attribute, which is enabled by the `SGR 9` escape sequence.
* Support for the escape sequences and storage of the attribute was
originally added in #2917.
* Support for drawing the strikethrough effect in the grid line renderer
was added in #7107.
Since the majority of the code required for this attribute had already
been implemented, it was just a matter of activating the
`GridLines::Strikethrough` style in the `Renderer::s_GetGridlines`
method when the `CrossedOut` attribute was set.
VALIDATION
There were already some unit tests in place in `VtRendererTest` and the
`ScreenBufferTests`, but I've also now extended the SGR tests in
`AdapterTest` to cover this attribute.
I've manually confirmed the first test case from #6205 now works as
expected in both conhost and Terminal.
Closes#6205
When we added support for win32 input mode, we neglected to pass
`ENHANCED_KEY` through the two surfaces that would generate events. This
broke arrow keys in much the same way was #2397, but in a different
layer.
While I was working on the WPF control, I took a moment to refactor the
message cracking out into a helper. It's a lot easier on the eyes than
four lines of bit shifting repeated three times.

This is a refactoring of the grid line renderers, adjusting the line
widths to scale with the font size, and optimising the implementation to
cut down on the number of draw calls. It also extends the supported grid
line types to include true underlines and strike-through lines in the
style of the active font.
The main gist of the optimisation was to render the horizontal lines
with a single draw call, instead of a loop with lots of little strokes
joined together. In the case of the vertical lines, which still needed
to be handled in a loop, I've tried to move the majority of static
calculations outside the loop, so there is bit of optimisation there
too.
At the same time this code was updated to support a variable stroke
width for the lines, instead of having them hardcoded to 1 pixel. The
width is now calculated as a fraction of the font size (0.025 "em"),
which is still going to be 1 pixel wide in most typical usage, but will
scale up appropriately if you zoom in far enough.
And in preparation for supporting the SGR strike-through attribute, and
true underlines, I've extended the grid line renders with options for
handling those line types as well. The offset and thickness of the lines
is obtained from the font metrics (rounded to a pixel width, with a
minimum of one pixel), so they match the style of the font.
VALIDATION
For now we're still only rendering grid lines, and only the top and
bottom lines in the case of the DirectX renderer in Windows Terminal. So
to test, I hacked in some code to force the renderer to use all the
different options, confirming that they were working in both the GDI and
DirectX renderers.
I've tested the output with a number of different fonts, comparing it
with the same text rendered in WordPad. For the most part they match
exactly, but there can be slight differences when we adjust the font
size for grid alignment. And in the case of the GDI renderer, where
we're working with pixel heights rather than points, it's difficult to
match the sizes exactly.
This is a first step towards supporting the strike-through attribute
(#6205) and true underlines (#2915).
Closes#6911
We've been trying to improve the copy/paste experience with the terminal
in Visual Studio. Once of our problematic scenarios is when the terminal
is connected to a remote environment and the user attempts to
copy/paste. This gets forwarded to the remote shell that copy/paste into
the remote clipboard instead of the local one.
So we opted to add ctrl+shift+c/v to the terminal and need access to the
selected text via the terminal control

Fixes#6966.
In UiaTextRange, `_getBufferSize` returns an optimized version of the
size of the buffer to be the origin and the last character in the
buffer. This is to improve performance on search or checking if you are
currently on the last word/line.
When setting the endpoint and drawing the bounding rectangles, we should
be retrieving the true buffer size. This is because it is still possible
to create UiaTextRanges that are outside of this optimized size. The
main source of this is `ExpandToEnclosingUnit()` when the unit is
`Document`. The end _should_ be the last visible character, but it isn't
because that would break our tests.
This is an incomplete solution. #6986 is a follow up to completely test
and implement the solution.
The crash in #6402 was caused by getting the document range (a range of
the full text buffer), then moving the end by one character. When we
get the document range, we get the optimized size of the buffer (the
position of the last character). Moving by one character is valid
because the buffer still has more to explore. We then crash from
checking if the new position is valid on the **optimized size**, not the
**real size**.

Out of the box, we ship a pretty bad behavior.
If I look at all of the existing shipped color schemes--and that
includes things like Tango and One Half--we are universally following a
`background` == `black` rule.
If I consult gnome-terminal or xterm, they do the same thing; Xterm by
default, gnome-terminal for solarized. The background generally matches
color index `0` across all their **dark** schemes. Konsole and
lxterminal disagree and map background to `0 intense` for Solarized.
I want to put our Solarized schemes on a deprecation path, but
unfortunately we still need to ship _something_ for users who we're
going to strand on them.
I'm going to have to swallow my bitter and say that yes, we should
probably just change the index mapping and go with something that works
right out of the box while we figure out how to do perceptual color
nudging and eventually remove bad defaults (like Solarized).

## Detailed Description of the Pull Request / Additional comments
One important part of this change concerns how panes are initialized at runtime. We've had some persistent trouble with initializing multiple panes, because they rely on knowing how big they'll actually be, to be able to determine if they can split again.
We previously worked around this by ignoring the size check when we were in "startup", processing an initial commandline. This PR however requires us to be able to know the initial size of a pane at runtime, but before the parents have necessarily been added to the tree, or had their renderer's set up.
This led to the development of `Pane::PreCalculateCanSplit`, which is very highly similar to `Pane::PreCalculateAutoSplit`. This method attempts to figure out how big a pane _will_ take, before the parent has necessarily laid out.
This also involves a small change to `TermControl`, because if its renderer hasn't been set up yet, it'll always think the font is `{0, fontHeight}`, which will let the Terminal keep splitting in the x direction. This change also makes the TermControl set up a renderer to get the real font size when it hasn't yet been initialized.
## Validation Steps Performed

```json

},

I also added some tests.

We spend a lot of time invalidating in the DX Renderer. This is a
creative trick to not bother invalidating any further if we can tell
that the bitmap is already completely invalidated. That is, if we've
scrolled at least an entire screen in height... then the entire bitmap
had to have been marked as invalid as the new areas were "uncovered" by
the `InvalidateScroll` command. So further setting invalid bits on top
of a fully invalid map is pointless.
Note: I didn't use `bitmap::all()` here because it is significantly
slower to check all the bits than it is to just reason out that the
bitmap was already fully marked.
## Validation Steps Performed
- Run `time cat big.txt`. Checked average time before/after, WPR traces

The act of calling `InsertAttrRuns` is relatively slow. Instead of
calling it a bunch of times to meddle with colors one cell at a time,
we'll accumulate a length of color and call it to make it act all at
once. This is great for when one color full line is getting replaced
with another color full line OR when a line is being replaced with the
same color all at once. There's significantly fewer checks to be made
inside `InsertAttrRuns` if we can help it out by accumulating the length
of each color before asking it to stitch it into the storage.

## Summary of the Pull Request
Text can have various attributes, such as "bold", "italic", "underlined", etc. The TextAttribute class embodies this. It has methods to set/query these attributes.
This change tweaks a few of the method names to make them match. I.e. for an imaginary text property "Foo", we should have methods along the lines of:
```
IsFoo
SetFoo(bool isFoo)
```
And variations should match: we should have "Foo" and "OverFoo", not "Fooey" and "OverFoo".
I chose to standardize on the adjective form, since that's what we are closest to already. The attributes I attacked here are:
SetItalic**s** --> SetItalic
SetUnderline --> SetUnderline**d**
SetOverline --> SetOverline**d**
("italic" is an adjective; "italics" is a plural noun, representing letters or words in an italic typeface)
And I also added methods for "DoublyUnderlined" for good measure.
I stopped short of renaming the GraphicsOptions enum values to match, too; but I'd be willing to do that in a follow-up change if people wanted it.
## Validation Steps Performed
It builds, and tests still pass.
This pull request converts the following JSON deserializers to use the
new JSON deserializer pattern:
* Profile
* Command
* ColorScheme
* Action/Args
* GlobalSettings
* CascadiaSettingsSerialization
This is the completion of a long-term JSON refactoring that makes our
parser and deserializer more type-safe and robust. We're finally able to
get rid of all our manual enum conversion code and unify JSON conversion
around _types_ instead of around _keys_.
I've introduced another file filled with template specializations,
TerminalSettingsSerializationHelpers.h, which comprises a single unit
that holds all of the JSON deserializers (and eventually serializers)
for every type that comes from TerminalApp or TerminalSettings.
I've also moved some types out of Profile and GlobalAppSettings into a
new SettingsTypes.h to improve settings locality.
This does to some extent constitute a breaking change for already-broken
settings. Instead of parsing "successfully" (where invalid values are
null or 0 or unknown or unset), deserialization will now fail when
there's a type mismatch. Because of that, some tests had to be removed.
While I was on a refactoring spree, I removed a number of helpless
helpers, like GetWstringFromJson (which converted a u8 string to an
hstring to make a wstring out of its data pointer :|) and
_ConvertJsonToBool.
In the future, we can make the error types more robust and give them
position and type information such that a conformant application can
display rich error information ("line 3 column 3, I expected a string,
you gave me an integer").
Closes#2550.
The command palette is a ListView of commands. As you type into the
search box, commands are added or removed from the ListView. Currently,
each update is done by completely clearing the backing list, then adding
back any items that should be displayed. However, this defeats the
ListView's built-in animations: upon every keystroke, ListView displays
its list-clearing animation, then animates the insertion of every item
that wasn't deleted. This results in noticeable flickering.
This PR changes the update logic so that it updates the list using
(roughly) the minimum number of Insert and Remove calls, so the ListView
makes smoother transitions as you type.
I implemented it by keeping the existing code that builds the filtered
list, but I changed it to build into a scratch list. Then I grafted on
a generic delta algorithm to make the real list look like the scratch
list.
To verify the delta algorithm, I tested all 360,000 permutations of
pairs of up to 5 element lists in a toy C# app.
## Validation
I'm not sure if my screen capture tool really caught all the flickering
here, but the screencasts below should give a rough idea of the
difference. (All the flickering was becoming a nuisance while I was

In `Renderer::TriggerRedraw`, the act of fetching the viewport from the
`pData` over and over is wasted time. We already have a cached variable
of the viewport that is updated on every scroll check (on
`TriggerScroll` and on `PaintFrame`.) Scrolling wouldn't be working
correctly if the clients weren't already notifying us that the viewport
has changed for scroll purposes, so we can just keep using that cached
value for the invalidation restriction to speed things up over fetching
it again.

## Summary of the Pull Request
This PR adds the `til::spsc` namespace, which implements a lock-free, single-producer, single-consumer FIFO queue ("channel"). The queue efficiently blocks the caller using Futexes if no data can be written to / read from the queue (e.g. using `WaitOnAddress` on Windows). Furthermore it allows batching of data and contains logic to signal the caller if the other side has been dropped/destructed.

## Detailed Description of the Pull Request / Additional comments
`til::spsc::details::arc<T>` contains most of the queue's logic and as such has the relevant documentation for its design.
## Validation Steps Performed
The queue was tested on Windows, Linux and macOS using MSVC, gcc and llvm and each of their available runtime introspection utilities in order to ensure no race conditions or memory leaks occur.
The recent changes to use gsl::span everywhere added a few bounds checks
along codepaths where we were already checking bounds. Some of them may
be non-obvious to the optimizer, so we can now use til::at to help them
along.
To accomplish this, I've added a new overload of til::at that takes a
span and directly accesses its backing buffer.
We were using std::basic_string_view as a stand-in for std::span so that
we could change over all at once when C++20 dropped with full span
support. That day's not here yet, but as of 54a7fce3e we're using GSL 3,
whose span is C++20-compliant.
This commit replaces every instance of basic_string_view that was not
referring to an actual string with a span of the appropriate type.
I moved the `const` qualifier into span's `T` because while
`basic_string_view.at()` returns `const T&`, `span.at()` returns `T&`
(without the const). I wanted to maintain the invariant that members of
the span were immutable.
* Mechanical Changes
* `sv.at(x)` -> `gsl::at(sp, x)`
* `sv.c{begin,end}` -> `sp.{begin,end}` (span's iterators are const)
I had to replace a `std::basic_string<>` with a `std::vector<>` in
ConImeInfo, and I chose to replace a manual array walk in
ScreenInfoUiaProviderBase with a ranged-for. Please review those
specifically.
This will almost certainly cause a code size regression in Windows
because I'm blowing out all the PGO counts. Whoops.

This results in smaller code and faster copying. I chose til::color even
though it results in slightly worse codegen (byteswapping in a tight
loop) than COLORREF (SSE-enlightened block copy) because eventually the
internal representations of the color tables will also be til::color and
_then_ it will become a block copy.
This PR adds support for always on top mode, via two mechanisms:
* The global setting `alwaysOnTop`. When set to true, the window will be
created in the "topmost" group of windows. Changing this value will
hot-reload whether the window is in the topmost group.
* The action `toggleAlwaysOnTop`, which will toggle the `alwaysOnTop`
property at runtime.
## Detailed Description of the Pull Request / Additional comments
All "topmost" windows maintain an internal z-ordering relative to one
another, but they're all always above all other "non-topmost" windows.
So multiple Windows Terminal windows which are both `alwaysOnTop` will
maintain a z-order relative to one another, but they'll all be on top of
all other windows.
## Validation Steps Performed
Toggled always on top mode, both in the settings and also at runtime,
and verified that it largely did what I expected.
Closes#3038
This adds `nt`, `sp`, and `ft` as aliases for `new-tab`, `split-pane`,
and `focus-tab`, respectively. These do exactly the same thing as their
long for counterparts, but are just shorter, for those of us who type
slower than a fifth grader 👀
Now you can do
```
wt nt cmd.exe /k #work 15 ; sp cmd.exe /k #work 15 ; sp cmd.exe /k
media-commandline ; nt powershell dev\\symbols.ps1 ; nt -p \"Ubuntu\" ;
nt -p \"Ubuntu\" ; ft -t 0
```
instead of
```
new-tab cmd.exe /k #work 15 ; split-pane cmd.exe /k #work 15 ;
split-pane cmd.exe /k media-commandline ; new-tab powershell
dev\\symbols.ps1 ; new-tab -p \"Ubuntu\" ; new-tab -p \"Ubuntu\" ;
focus-tab -t 0
```
The pattern I'm using here is that each of these subcommands now has a
little helper lambda that actually sets up the subcommand with the
required arguments, and we just call that lambda twice, once for the
long-form of the command, and again for the short.
I imagine that in the future, we won't necessarily have short-forms for
every subcommands, so if there are future conflicts we'd have to figure
that out pre-emptively, but these all seem like they'll need a short
form.
Closes#5466
GSL 3, the next major version of GSL after the one we're using, replaced
their local implementation of `span` with one that more closely mimics
C++20's span. Unfortunately, that is a breaking change for all of GSL's
consumers.
This commit updates our use of span to comply with the new changes in
GSL 3.
Chief among those breaking changes is:
* `span::at` no longer exists; I replaced many instances of `span::at`
with `gsl::at(x)`
* `span::size_type` has finally given up on `ptrdiff_t` and become
`size_t` like all other containers
While I was here, I also made the following mechanical replacements:
* In some of our "early standardized" code, we used std::optional's
`has_value` and `value` back-to-back. Each `value` incurs an
additional presence test.
* Change: `x.value().member` -> `x->member` (`optional::operator->`
skips the presence test)
* Change: `x.value()` -> `*x` (as above)
* GSL 3 uses `size_t` for `size_type`.
* Change: `gsl::narrow<size_t>(x.size())` -> `x.size()`
* Change: `gsl::narrow<ptrdiff_t>(nonSpan.size())` -> `nonSpan.size()`
during span construction
I also replaced two instances of `x[x.size() - 1]` with `x.back()` and
one instance of a manual array walk (for comparison) with a direct
comparison.
NOTE: Span comparison and `make_span` are not part of the C++20 span
library.

## Summary of the Pull Request
This PR adds support for the `SGR 8` and `SGR 28` escape sequences,
which enable and disable the _concealed/invisible_ graphic rendition
attribute. When a character is output with this attribute set, it is
rendered with the same foreground and background colors, so the text is
essentially invisible.

## Detailed Description of the Pull Request / Additional comments
Most of the framework for this attribute was already implemented, so it
was just a matter of updating the `TextAttribute::CalculateRgbColors`
method to make the foreground the same as the background when the
_Invisible_ flag was set. Note that this has to happen after the
_Reverse Video_ attribute is applied, so if you have white-on-black text
that is reversed and invisible, it should be all white, rather than all
black.
## Validation Steps Performed
There were already existing SGR unit tests covering this attribute in
the `ScreenBufferTests`, and the `VtRendererTest`. But I've added to the
`AdapterTest` which verifies the SGR sequences for setting and resetting
the attribute, and I've extended the `TextAttributeTests` to verify that
the color calculations return the correct values when the attribute is
set.
I've also manually confirmed that we now render the _concealed text_
values correctly in the _ISO 6429_ tests in Vttest. And I've manually
tested the output of _concealed_ when combined with other attributes,
and made sure that we're matching the behaviour of most other terminals.
This parameter was added as a workaround for our fast trackpad
scrolling. Since that was fixed before 1.0 shipped, in #4554, it has
been largely vestigial. There is no reason for us to keep it around any
longer.
It was also the only "logic" in TerminalSettings, which is otherwise a
library that only transits data between two other libraries.
I have not removed it from the schema, as I do not want to mark folks'
settings files invalid to a strict schema parser.
While I was in the area, I added support for "scroll one screen at a
time" (which is represented by the API returning WHEEL_PAGESCROLL),
fixing #5610. We were also storing it in an int (whoops) instead of a
uint.
Fixes#5610
console: switch to /Zc:wchar_t (native wchar_t)

## Summary of the Pull Request

foreground color.

## Detailed Description of the Pull Request / Additional comments
There was already an `ExtendedAttributes::Faint` flag in the
`TextAttribute` class, but I needed to add `SetFaint` and `IsFaint`
methods to access that flag, and update the `SetGraphicsRendition`
methods of the two dispatchers to set the attribute on receipt of the
`SGR 2` sequence. I also had to update the existing `SGR 22` handler to
reset _Faint_ in addition to _Bold_, since they share the same reset
sequence. For that reason, I thought it a good idea to change the name
of the `SGR 22` enum to `NotBoldOrFaint`.
For the purpose of rendering, I've updated the
`TextAttribute::CalculateRgbColors` method to return a dimmer version of
the foreground color when the _Faint_ attribute is set. This is simply
achieved by dividing each color component by two, which produces a
reasonable effect without being too complicated. Note that the _Faint_
effect is applied before _Reverse Video_, so if the output it reversed,
it's the background that will be faint.
The only other complication was the update of the `Xterm256Engine` in
the VT renderer. As mentioned above, _Bold_ and _Faint_ share the same
reset sequence, so to forward that state over conpty we have to go
through a slightly more complicated process than with other attributes.
We first check whether either attribute needs to be turned off to send
the reset sequence, and then check if the individual attributes need to
be turned on again.
## Validation
I've extended the existing SGR unit tests to cover the new attribute in
the `AdapterTest`, the `ScreenBufferTests`, and the `VtRendererTest`,
and added a test to confirm the color calculations when _Faint_ is set
in the `TextAttributeTests`.
I've also done a bunch of manual testing with all the different VT color
types and confirmed that our output is comparable to most other
terminals.
## Summary of the Pull Request
Add support for "focus" mode, which only displays the actual terminal content, no tabs or titlebar. The edges of the window are draggable to resize, but the window can't be moved in borderless mode.
The window looks _slightly_ different bewteen different values for `showTabsInTitlebar`, because switching between the `NonClientIslandWindow` and the `IslandWindow` is _hard_.

This commit updates JsonUtilsNew to support winrt
`Windows::Foundation::IReference<T>` as an option type, and cleans up the
optional support code by removing the optional overload on
`GetValue(...)`. Instead of using an overload with a partial
specialization, we're using a constexpr if with a type trait to
determine option-type-ness.
In addition, Carlos reported an issue with deriving from `FlagMapper`
(itself templated) and referring to the base type's members without
fully qualifying them. To make derivation easier, `EnumMapper` and
`FlagMapper` now provide `BaseEnumMapper` and `BaseFlagMapper` type
aliases.
I've taken the opportunity to add a `winrt::hstring` conversion
trait.
Lastly, in casual use, I found out that I'd written the til::color
converter wrong: it supports color strings of length 7 (`#rrggbb`) and
length 4 (`#rgb`). I mistyped (and failed to test) support for 4-length
color strings by pretending they were only 3 characters long.

Due to a shell limitation, Ctrl+Shift+Enter will not launch Windows
Terminal as Administrator. This is caused by the app execution alias and
the actual targeted executable not having the same name.
In addition, PowerShell has an issue detecting app execution aliases as
GUI/TUI applications. When you run wt from PowerShell, the shell will
wait for WT to exit before returning to the prompt. Having a shim that
immediately re-executes WindowsTerminal and then returns handily knocks
this issue out (as the process that PS was waiting for exits
immediately.)
This could cause a regression for anybody who tries to capture the PID
of wt.exe. Our process tree is not an API, and we have offered no
consistency guarantee on it.

This PR adds support for the `DA2` (Secondary Device Attributes) and
`DA3` (Tertiary Device Attributes) escape sequences, which are standard
VT queries reporting basic information about the terminal.
The _Secondary Device Attributes_ response is made up of a number of
parameters:
1. An identification code, for which I've used 0 to indicate that we
have the capabilities of a VT100 (using code 0 for this is an XTerm
convention, since technically DA2 would not have been supported by a
VT100).
2. A firmware revision level, which some terminal emulators use to
report their actual version number, but I thought it best we just
hardcode a value of 10 (the DEC convention for 1.0).
3. Additional hardware options, which tend to be device specific, but
I've followed the convention of the later DEC terminals using 1 to
indicate the presence of a PC keyboard.
The _Tertiary Device Attributes_ response was originally used to provide
a unique terminal identification code, and which some terminal emulators
use as a way to identify themselves. However, I think that's information
we'd probably prefer not to reveal, so I've followed the more common
practice of returning all zeros for the ID.
In terms of implementation, the only complication was the need to add an
additional code path in the `OutputStateMachine` to handle the `>` and
`=` intermediates (technically private parameter prefixes) that these
sequences require. I've done this as a single method - rather than one
for each prefix - since I think that makes the code easier to follow.
VALIDATION
----------
I've added output engine tests to make sure the sequences are dispatched
correctly, and adapter tests to confirm that they are returning the
responses we expect. I've also manually confirmed that they pass the
_Test of terminal reports_ in Vttest.
Closes#5836
This is a refactoring of the renderer color calculations to simplify the
implementation, and to make it easier to support additional
color-altering rendition attributes in the future (e.g. _faint_ and
_conceal_).
## References
* This is a followup to PRs #3817 and #6809, which introduced additional
complexity in the color calculations, and which suggested the need for
refactoring.
## Detailed Description of the Pull Request / Additional comments
When we added support for `DECSCNM`, that required the foreground and
background color lookup methods to be able to return the opposite of
what was requested when the reversed mode was set. That made those
methods unnecessarily complicated, and I thought we could simplify them
considerably just by combining the calculations into a single method
that derived both colors at the same time.
And since both conhost and Windows Terminal needed to perform the same
calculations, it also made sense to move that functionality into the
`TextAttribute` class, where it could easily be shared.
In general this way of doing things is a bit more efficient. However, it
does result in some unnecessary work when only one of the colors is
required, as is the case for the gridline painter. So to make that less
of an issue, I've reordered the gridline code a bit so it at least
avoids looking up the colors when no gridlines are needed.
## Validation Steps Performed
Because of the API changes, quite a lot of the unit tests had to be
updated. For example instead of verifying colors with two separate calls
to `LookupForegroundColor` and `LookupBackgroundColor`, that's now
achieved with a single `LookupAttributeColors` call, comparing against a
pair of values. The specifics of the tests haven't changed though, and
they're all still working as expected.
I've also manually confirmed that the various color sequences and
rendition attributes are rendering correctly with the new refactoring.
There is going to be a very long tail of applications that will
explicitly request VT SGR 40/37 when what they really want is to
SetConsoleTextAttribute() with a black background/white foreground.
Instead of making those applications look bad (and therefore making us
look bad, because we're releasing this as an update to something that
"looks good" already), we're introducing this compatibility quirk.
Before the color reckoning in #6698 + #6506, *every* color was subject
to being spontaneously and erroneously turned into the default color.
Now, only the 16-color palette value that matches the active console
background/foreground color will be destroyed, and only when received
from specific applications.
Removal will be tracked by #6807.
Michael and I discussed what layer this quirk really belonged in. I
originally believed it would be sufficient to detect a background color
that matched the legacy default background, but @j4james provided an
example of where that wouldn't work out (powershell setting the
foreground color to white/gray). In addition, it was too heavyhanded: it
re-broke black backgrounds for every application.
Michael thought that it should live in the server, as a small VT parser
that righted the wrongs coming directly out of the application. On
further investigation, however, I realized that we'd need to push more
information up into the server (so that it could make the decision about
which VT was wrong and which was right) than should be strictly
necessary.
The host knows which colors are right and wrong, and it gets final say
in what ends up in the buffer.
Because of that, I chose to push the quirk state down through
WriteConsole to DoWriteConsole and toggle state on the
SCREEN_INFORMATION that indicates whether the colors coming out of the
application are to be distrusted. This quirk _only applies to pwsh.exe
and powershell.exe._
NOTE: This doesn't work for PowerShell the .NET Global tool, because it
is run as an assembly through dotnet.exe. I have no opinion on how to
fix this, or whether it is worth fixing.
VALIDATION
----------
I configured my terminals to have an incredibly garish color scheme to
show exactly what's going to happen as a result of this. The _default
terminal background_ is purple or red, and the foreground green. I've
printed out a heap of test colors to see how black interacts with them.
Pull request #6810 contains the images generated from this test.
The only color lines that change are the ones where black as a
background or white as a foreground is selected out of the 16-color
palette explicitly. Reverse video still works fine (because black is in
the foreground!), and it's even possible to represent "black on default"
and reverse it into "default on black", despite the black in question
having been `40`.
Fixes#6767.
By storing up the accumulated delta in the mouse input handler, we can
enlighten both conhost and terminal about wheel events that are less
than one line in size. Previously, we had a workaround in conhost that
clamped small scroll deltas to a whole line, which made trackpad
scrolling unimaginably fast. Terminal didn't make this mistake, but it
also didn't handle delta accumulation . . . which resulted in the same
behavior.
MouseInput will now wait until it's received WHEEL_DELTA (well-known
constant, value 120) worth of scrolling delta before it dispatches a
single scroll event.
Future considerations may include sending multiple wheel button events
for every *multiple* of WHEEL_DELTA, but that would be a slightly larger
refactoring that I'm not yet ready to undertake.
There's a chance that we should be dividing WHEEL_DELTA by the system's
"number of lines to scroll at once" setting, because on trackpads
conhost now scrolls a little _slow_. I think the only way to determine
whether this is palatable is to just ship it.
Fixes#6184.

## Detailed Description of the Pull Request / Additional comments
The `AdaptDispatch::SetScreenMode` now checks if it's in conpty mode and simply returns false to force a pass-through of the mode change. And the `TerminalDispatch` now has its own `SetScreenMode` implementation that tracks any changes to the reversed state, and triggers a redraw in the renderer.
To make the renderer work, we just needed to update the `GetForegroundColor` and `GetBackgroundColor` methods of the terminal's `IRenderData` implementation to check the reversed state, and switch the colors being calculated, the same way the `LookupForegroundColor` and `LookupBackgroundColor` methods work in the conhost `Settings` class.
## Validation Steps Performed

## Detailed Description of the Pull Request / Additional comments
Updates the `_scrollOffset` value properly in TerminalCore when the cursor moves. We calculate a new `_scrollOffset` based on if we are circling the buffer and how far below the mutable bottom is.
We specifically check for if a selection is active and if the viewport is at the bottom, then use that as a condition for deciding if we should update `_scrollOffset` to the new calculated value or 0 (the bottom of the scroll history).
## Validation Steps Performed
Manual testing. Though I should add automated tests.
- [X] new output
- [X] new output when circling
- [X] new output when circling and viewport is at the top
Looking up the size of the viewport from the underlying dimensions of
the structures seemed like a good idea at the time (so it would only be
in one place), but it turns out to be more of a perf cost than we
expected. Not necessarily on any one hot path, but if we sort by
functions in WPR, it was the top consumer on the Terminal side. This
instead saves the size as a member of the `TextBuffer` and serves that
out. It only changes when it is constructed or resized traditionally, so
it's easy to update/keep track of. It impacted conhost/conpty to a
lesser degree but was still noticeable.

The main change in 16.7 is the separation of `AppContainerApplication`
into `WindowsStoreApp` and `WindowsAppContainer`. There's been a bit of
interest in splitting packaging away from containment, and this is the
first step in that direction.
We're a somewhat unique application, but as WinUI3 becomes more
prevalent we will become _less_ unique.
Some of these things, I've looked at and wondered how they ever worked.

A lot of time was spent between each individual line in the VT paint
engine in allocating some scratch space to assemble the clusters then
deallocating it only to have the next line do that again. Now we just

continues.

## Detailed Description of the Pull Request / Additional comments
Passes the bitmap by ref into the tracing function instead of making a copy on the way in. It's only read anyway for tracing (if enabled) so the copy was a pointless oversight.
## Validation Steps Performed
- Observed WPR trace before and after with `time cat big.txt` in WSL.
This PR enables `ApplicationHighContrastAdjustment::None`. Doing this
disables a set of mitigations in XAML designed to band-aid apps that
were never explicitly designed for High Contrast (HC) modes. Terminal
now has full control of and responsibility for its appearance in HC
mode. This allows Terminal to look a lot better.
On paper, we should be able to set `HighContrastAdjustment="None"` on
the `<Application>` element. But that doesn't have any effect. I don't
know if this is a bug in `<Toolkit:XamlApplication>` or somewhere else.
So instead I set the property in codebehind, which is not as ideal, but
does at least work. I'd love to a way to move this into App.xaml.
The Find box had a couple stray styles to override the ToggleButton's
foreground color. With backplating removed, these styles became
actively harmful (white foreground on highlight color background), so I
just removed them. The built-in style for ToggleButton is perfect
as-is.
Closes#5360
WinUI's `Margin` and `Padding` work very similarly. `Margin` distances
ourselves from our parent. Whereas `Padding` distances our children from
ourselves.
Terminal's `padding` setting is actually implemented by defining
`Margin` on the SwapChainPanel. This means that the "padding" that is
created is actually belongs to SwapChainPanel's parent: Grid (not to be
confused with its parent, "RootGrid").
When a user clicks on the padded area, input goes to Grid. But there's a
twist: you can't actually hit Grid. To be able to hit Grid, you can't
just set IsHitTestVisible. You need to set it's Visibility to Visible,
and it's Background to Transparent (not null) [2].
## Validation Steps Performed
- [X] Start a selection from the padding area
- [X] Click on a SearchBox if one is available
- The SearchBox gets first dibs on the hit test so none gets through
to the SwapChainPanel

## Summary of the Pull Request
In the wake of #6635, a couple things got missed in merges:
* `toggleRetroEffect` didn't get into the schema, nor did `renameTab` or
`commandPalette`.
* `toggleRetroEffect` also didn't get a name
Furthermore, I thought it might be a good idea to start sticking
commands into `bindings` even without `keys`. So I tried doing that for
`opentabColorPicker` and `toggleRetroEffect`, and found immediately that
the labels for the key chord still appear even when the text is empty.
So I added some XAML magic to hide those when the text is empty.

Update colors of our custom NewTab button to match MUX's TabView button
MUX has a NewTab button, but Terminal uses a homemade lookalike. The
version in Terminal doesn't use the same brush color resources as MUX's
button, so it looks very slightly different. This PR updates Terminal's
button to use the exact same colors that MUX uses. I literally copied
these brush names out of MUX source code.
## References
This is the color version of the layout fix#6766
This is a prerequisite for fixing #5360
## Detailed Description of the Pull Request / Additional comments
The real reason that this matters is that once you flip on
`ApplicationHighContrastAdjustment::None`, the existing colors will not
work at all. The existing brushes are themed to black foreground on a
black background when High Contrast (HC) Black theme is enabled. The
only thing that's saving you is
`ApplicationHighContrastAdjustment::Auto` is automatically backplating
the glyphs on the buttons, which (by design) hides the fact that the
colors are poor. The backplates are those ugly squares inside the
buttons on the HC themes.
Before I can push a PR that disables automatic backplating (set
`ApplicationHighContrastAdjustment` to `None`), we'll need to select
better brushes that work in HC mode. MUX has already selected brushes
that work great in all modes, so it just makes sense to use their
brushes.
The one very subtle difference here is that, for non-HC themes, the
glyph's foreground has a bit more contrast when the button is in
hovered/pressed states. Again this slight difference hardly matters
now, but using the correct brushes will become critical when we try to
remove the HC backplating.
Closes#6812

The MUX TabView control has a uniquely-shaped [+] button. TerminalApp
doesn't use it: instead, it has a SplitView button that is styled to
look like MUX's official button. However, it doesn't get the button's
shape right. This PR updates TerminalApp's custom button to look more
like MUX's.
The difference is that MUX only rounds the top two corners, and it uses
a bigger radius. Without matching MUX's radius, the upper-left corner
of the button makes an awkward asymmetric divot with the abutting tab.
There's also a spot in the lower-left corner that just looks like
someone accidentally spilled a few pixels on the floor.

## Summary of the Pull Request
This PR adds support for the `SGR 53` and `SGR 55` escapes sequences,
which enable and disable the ANSI _overline_ graphic rendition
attribute, the equivalent of the console character attribute
`COMMON_LVB_GRID_HORIZONTAL`. When a character is output with this
attribute set, a horizontal line is rendered at the top of the character
cell.

## Detailed Description of the Pull Request / Additional comments
To start with, I added `SetOverline` and `IsOverlined` methods to the
`TextAttribute` class, to set and get the legacy
`COMMON_LVB_GRID_HORIZONTAL` attribute. Technically there was already an
`IsTopHorizontalDisplayed` method, but I thought it more readable to add
a separate `IsOverlined` as an alias for that.
Then it was just a matter of adding calls to set and reset the attribute
in response to the `SGR 53` and `SGR 55` sequences in the
`SetGraphicsRendition` methods of the two dispatchers. The actual
rendering was already taken care of by the `PaintBufferGridLines` method
in the rendering engines.
The only other change required was to update the `_UpdateExtendedAttrs`
method in the `Xterm256Engine` of the VT renderer, to ensure the
attribute state would be forwarded to the Windows Terminal over conpty.
## Validation Steps Performed
I've extended the existing SGR unit tests to cover the new attribute in
the `AdapterTest`, the `OutputEngineTest`, and the `VtRendererTest`.
I've also manually tested the `SGR 53` and `SGR 55` sequences to confirm
that they do actually render (or remove) an overline on the characters
being output.
The VT reset operations `RIS` and `DECSTR` are implemented as a series
of steps, each of which could potentially fail. Currently these
operations abort as soon as an error is detected, which is particularly
problematic in conpty mode, where some steps deliberately "fail" to
indicate that they need to be "passed through" to the conpty client. As
a result, the reset won't be fully executed. This PR changes that
behaviour, so the error state is recorded for any failures, but the
subsequent steps are still run.
Originally the structure of these operations was of the form:
bool success = DoSomething();
if (success)
{
success = DoSomethingElse();
}
But I've now changed the code so it looks more like this:
bool success = DoSomething();
success = DoSomethingElse() && success;
This means that every one of the steps should execute, regardless of
whether previous steps were successful, but the final _success_ state
will only be true if none of the steps has failed.
While this is only really an issue in the conhost code, I've updated
both the `AdaptDispatch` and `TerminalDispatch` classes, since I thought
it would be best to have them in sync, and in general this seems like a
better way to handle multi-step operations anyway.
VALIDATION
I've manually tested the `RIS` escape sequence (`\ec`) in the Windows
Terminal, and confirmed that it now correctly resets the cursor
position, which it wasn't doing before.
Closes#6545
Pretty straightforward. `toggleRetroEffect` will work to toggle the
retro terminal effect on/off.
* Made possible by contributions from #6551, _and viewers like you_
This PR fixes the scheme resolution bug outlined in #5326
The approach is as follows:
* In [SchemeManager.cs], find the first scheme parser that actually
successfully parses the scheme, as opposed to the existing code, which
finds the first scheme parser which _says it can parse the scheme_, as
that logic spuriously returns `true` currently.
* In [XmlSchemeParser.cs] and [JsonParser.cs], ensure that the contents
of the file are read and the contents passed to XmlDocument.LoadXXX,
as this fails with an UriException on WSL otherwise.
* Remove `CanParse` as it is superfluous. The check for a valid scheme
parser should not just check an extension but also if the file exists
- this is best done by the `ParseScheme` function as it already
returns null on failure.
* Add `FileExtension` to the interface because we need it lifted now.
Closes#5326
Before sending calling the `HandleClipboardData` member function on
the `PasteFromClipboardEventArgs` object when we receive a request
from the `TermControl` to send it the clipboard's text content, we
now display a warning to let the user choose whether to continue or
not if the text is larger than 5 KiB or contains the _new line_
character, which can be a security issue if the user is pasting the
text in a shell.
These warnings can be disabled with the `largePasteWarning` and
`multiLinePasteWarning` global settings respectively.
Closes#2349
This is essentially a rewrite of the
`TerminalDispatch::SetGraphicsRendition` method, bringing it into closer
alignment with the `AdaptDispatch` implementation, simplifying the
`ITerminalApi` interface, and making the code easier to extend. It adds
support for a number of attributes which weren't previously implemented.
REFERENCES
* This is a mirror of the `AdaptDispatch` refactoring in PR #5758.
* The closer alignment with `AdaptDispatch` is a small step towards
solving issue #3849.
* The newly supported attributes should help a little with issues #5461
(italics) and #6205 (strike-through).
DETAILS
I've literally copied and pasted the `SetGraphicsRendition`
implementation from `AdaptDispatch` into `TerminalDispatch`, with only
few minor changes:
* The `SetTextAttribute` and `GetTextAttribute` calls are slightly
different in the `TerminalDispatch` version, since they don't return a
pointless `success` value, and in the case of the getter, the
`TextAttribute` is returned directly instead of by reference.
Ultimately I'd like to move the `AdaptDispatch` code towards that way
of doing things too, but I'd like to deal with that later as part of a
wider refactoring of the `ConGetSet` interface.
* The `SetIndexedForeground256` and `SetIndexedBackground256` calls
required the color indices to be remapped in the `AdaptDispatch`
implementation, because the conhost color table is in a different
order to the XTerm standard. `TerminalDispatch` doesn't have that
problem, so doesn't require the mapping.
* The index color constants used in the 16-color `SetIndexedForeground`
and `SetIndexedBackground` calls are also slightly different for the
same reason.
VALIDATION
I cherry-picked this code on top of the #6506 and #6698 PRs, since
that's only way to really get the different color formats passed-through
to the terminal. I then ran a bunch of manual tests with various color
coverage scripts that I have, and confirmed that all the different color
formats were being rendered as expected.
Closes#6725
This PR reimplements the VT rendering engines to do a better job of
preserving the original color types when propagating attributes over
ConPTY. For the 16-color renderers it provides better support for
default colors and improves the efficiency of the color narrowing
conversions. It also fixes problems with the ordering of character
renditions that could result in attributes being dropped.
Originally the base renderer would calculate the RGB color values and
legacy/extended attributes up front, passing that data on to the active
engine's `UpdateDrawingBrushes` method. With this new implementation,
the renderer now just passes through the original `TextAttribute` along
with an `IRenderData` interface, and leaves it to the engines to extract
the information they need.
The GDI and DirectX engines now have to lookup the RGB colors themselves
(via simple `IRenderData` calls), but have no need for the other
attributes. The VT engines extract the information that they need from
the `TextAttribute`, instead of having to reverse engineer it from
`COLORREF`s.
The process for the 256-color Xterm engine starts with a check for
default colors. If both foreground and background are default, it
outputs a SGR 0 reset, and clears the `_lastTextAttribute` completely to
make sure any reset state is reapplied. With that out the way, the
foreground and background are updated (if changed) in one of 4 ways.
They can either be a default value (SGR 39 and 49), a 16-color index
(using ANSI or AIX sequences), a 256-color index, or a 24-bit RGB value
(both using SGR 38 and 48 sequences).
Then once the colors are accounted for, there is a separate step that
handles the character rendition attributes (bold, italics, underline,
etc.) This step must come _after_ the color sequences, in case a SGR
reset is required, which would otherwise have cleared any character
rendition attributes if it came last (which is what happened in the
original implementation).
The process for the 16-color engines is a little different. The target
client in this case (Windows telnet) is incapable of setting default
colors individually, so we need to output an SGR 0 reset if _either_
color has changed to default. With that out the way, we use the
`TextColor::GetLegacyIndex` method to obtain an approximate 16-color
index for each color, and apply the bold attribute by brightening the
foreground index (setting bit 8) if the color type permits that.
However, since Windows telnet only supports the 8 basic ANSI colors, the
best we can do for bright colors is to output an SGR 1 attribute to get
a bright foreground. There is nothing we can do about a bright
background, so after that we just have to drop the high bit from the
colors. If the resulting index values have changed from what they were
before, we then output ANSI 8-color SGR sequences to update them.
As with the 256-color engine, there is also a final step to handle the
character rendition attributes. But in this case, the only supported
attributes are underline and reversed video.
Since the VT engines no longer depend on the active color table and
default color values, there was quite a lot of code that could now be
removed. This included the `IDefaultColorProvider` interface and
implementations, the `Find(Nearest)TableIndex` functions, and also the
associated HLS conversion and difference calculations.
VALIDATION
Other than simple API parameter changes, the majority of updates
required in the unit tests were to correct assumptions about the way the
colors should be rendered, which were the source of the narrowing bugs
this PR was trying to fix. Like passing white on black to the
`UpdateDrawingBrushes` API, and expecting it to output the default `SGR
0` sequence, or passing an RGB color and expecting an indexed SGR
sequence.
In addition to that, I've added some VT renderer tests to make sure the
rendition attributes (bold, underline, etc) are correctly retained when
a default color update causes an `SGR 0` sequence to be generated (the
source of bug #3076). And I've extended the VT renderer color tests
(both 256-color and 16-color) to make sure we're covering all of the
different color types (default, RGB, and both forms of indexed colors).
I've also tried to manually verify that all of the test cases in the
linked bug reports (and their associated duplicates) are now fixed when
this PR is applied.
Closes#2661Closes#3076Closes#3717Closes#5384Closes#5864
This is only a partial fix for #293, but I suspect the remaining cases
are unfixable.
Essentially what this does is map the default legacy foreground and
background attributes (typically white on black) to the `IsDefault`
color type in the `TextColor` class. As a result, we can now initialize
the buffer for "legacy" shells (like PowerShell and cmd.exe) with
default colors, instead of white on black. This fixes the startup
rendering in conpty clients, which expect an initial default background
color. It also makes these colors update appropriately when the default
palette values change.
One complication in getting this to work, is that the console permits
users to change which color indices are designated as defaults, so we
can't assume they'll always be white on black. This means that the
legacy-to-`TextAttribute` conversion will need access to those default
values.
Unfortunately the defaults are stored in the conhost `Settings` class
(the `_wFillAttribute` field), which isn't easily accessible to all the
code that needs to construct a `TextAttribute` from a legacy value. The
`OutputCellIterator` is particularly problematic, because some iterator
types need to generate a new `TextAttribute` on every iteration.
So after trying a couple of different approaches, I decided that the
least worst option would be to add a pair of static properties for the
legacy defaults in the `TextAttribute` class itself, then refresh those
values from the `Settings` class whenever the defaults changed (this
only happens on startup, or when the conhost _Properties_ dialog is
edited).
And once the `TextAttribute` class had access to those defaults, it was
fairly easy to adapt the constructor to handle the conversion of default
values to the `IsDefault` color type. I could also then simplify the
`TextAttribute::GetLegacyAttributes` method which does the reverse
mapping, and which previously required the default values to be passed
in as a parameter
VALIDATION
I had to make one small change to the `TestRoundtripExhaustive` unit
test which assumed that all legacy attributes would convert to legacy
color types, which is no longer the case, but otherwise all the existing
tests passed as is. I added a new unit test verifying that the default
legacy attributes correctly mapped to default color types, and the
default color types were mapped back to the correct legacy attributes.
I've manually confirmed that this fixed the issue raised in #5952,
namely that the conhost screen is cleared with the correct default
colors, and also that it is correctly refreshed when changing the
palette from the properties dialog. And I've combined this PR with
#6506, and confirmed that the PowerShell and the cmd shell renderings in
Windows Terminal are at least improved, if not always perfect.
This is a prerequisite for PR #6506Closes#5952
With this commit, terminal will be able to copy text to the system
clipboard by using OSC 52 MANIPULATE SELECTION DAATA.
We chose not to implement the clipboard querying functionality offered
by OSC 52, as sending the clipboard text to an application without the
user's knowledge or consent is an immense security hole.
We do not currently support the clipboard specifier Pc to specify which
clipboard buffer should be filled

Restores the simple text run analysis and skipping of most of the
shaping/layout steps. Corrects one of the fast-path steps to ensure that
offsets and clusters are assigned.
## References
- Bug #6488
- Bug #6664
- Simple run PR #6206
- Simple run revert PR #6665
- Recycle glyph runs PR #6483
The "correction" functions, by which box drawing analysis is one of
them, is dependent on the steps coming before it properly assigning the
four main vectors of the text layout glyphs: indices, advances, offsets,
and clusters. When the fast path is identified by the code from #6206,
only two of those are fully updated: indices and advances. The offsets
doesn't tend to cause a problem because offsets are rarely used so
they're pretty much always 0 already (but this PR enforces that they're
zero for the simple/fast path.) The clusters, however, were not mapped
for the fast path. This showed itself in one of two ways:
1. Before the recycled runs PR #6483, the cluster map had a 0 in every
field for the stock initialized vector.
2. After the recycled runs PR #6483, the cluster map had the previous
run's mapping in it.
This meant that when we reached the steps where glyph runs were
potentially split during the correction phase for box drawing
characters, unexpected values were present to map the glyph indices to
clusters and were corrected, adjusted, or split in an unexpected
fashion.
For instance, the index out of range bug could appear when the default 0
values appended to the end of the clusters vector were decremented down
to a negative value during the run splitter as the true DWrite cluster
mapper doesn't generate that sort of pattern in the slow path case
without also breaking the run itself.
The resolution here is therefore to ensure that all of the fields
related to glyph layout are populated even in the fast path. This
doesn't affect the slow path because that one always populated all
fields by asking DWrite to do it. The fast path just skips a bunch of
DWrite steps because it can implicitly identify patterns and save a
bunch of time.
I've also identified a few vectors that weren't cleared on reset/reuse
of the layout. I'm clearing those now so the `.resize()` operations
performed on them to get to the correct lengths will fill them with
fresh and empty values instead of hanging on to ones that may have been
from the previous. This should be OK memory perf wise because the act of
`.clear()` on a vector shouldn't free anything, just mark it invalid.
And doing `.resize()` from an empty one should just default construct
them into already allocated space (which ought to be super quick).

## Summary of the Pull Request
This adds a first iteration on the command palette. Notable missing features are:
* Commandline mode: This will be a follow-up PR, following the merge of #6537
* nested and iterable commands: These will additionally be a follow-up PR.
This is also additionally based off the addenda in #6532.
This does not bind a key for the palette by default. That will be done when the above follow-ups are completed.

Occasionally, we get users with corrupt PATH environment variables: they
can't lauch PowerShell, because for some reason it's dropped off their
PATH. We also get users who have stray applications named
`powershell.exe` just lying around in random system directories.
We can combat both of these issues by simply hardcoding where we expect
PowerShell and CMD to live. %SystemRoot% was chosen over %WINDIR%
because apparently (according to Stack Overflow), SystemPath is
read-only and WINDIR isn't.

This pull request implements shift+double/triple click. Proper behavior
(as described in #4557) is to only expand one selection point, not both.
Adding the `bool targetStart` was a bit weird. I decided on this being
the cleanest approach though because I still want `PivotSelection` to be
its own helper function. Otherwise, the concept of "pivoting" gets kinda
messy.
## Validation Steps Performed
Manual testing as described on attached issue.
Tests were added for Shift+Click and pivoting the selection too.
Closes#4557
This reverts commit 94eab6e391.
We'll reintroduce this again after making sure it plays nicely with
recycling and box drawing glyphs.

## Detailed Description of the Pull Request / Additional comments
I added a handler for the `DoubleTapped` event on the tab view item
when we are constructing it for the tab (in `Tab::_MakeTabViewItem`).
The code for that handler was copied the "rename tab menu item" click
handler.
I did not extract the code into a member function because it is very
short (only 2 lines of code) and only used twice so it is not worth
it IMO.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
This saves an awful lot of construction/destruction and memory
allocation, especially with text that changes a lot (see: cacafire).
Three things:
1. Recycling the text layouts. This holds onto the `CustomTextLayout` so
all the things that don't change related to drawing targets and
whatnot aren't freed and recreated every frame.
2. Reordering the runs in place. This saves a vector
allocation/copy/delete every time OrderRuns is called. They can be
rearranged in place.
3. Only clip once per row. This reduces the clip push/pop to only one
time per row. Since we're always redrawing an entire row at a time,
this saves a lot of alloc/free of the clip frame, dramatically
reduces queued commands, and makes less work on the flush since
clipping requires staging the drawing and then bringing it back to
the main surface.
I was told that the DeviceContext version supercedes the RenderTarget
one. This moves us to it so we can gain access to a higher level of
control over the various pieces in our pipeline as we continue to evolve
the renderer.
The underlying motivation here is to potentially use a
`ID2D1CommandList` to batch our commands and run them all later outside
the lock. That can only really be done with this more granular level of
control over the pipeline. So this moves to that in a single step that
is easily findable in history should we have problems
I discussed this with @NiklasBorson of the Direct2D/DirectWrite team as
well as with @DHowett before doing it.

## Detailed Description of the Pull Request / Additional comments
- I found four settings that weren't hot reloadable with the 3927 comment above them:
1. Experimental retro terminal effect
2. Experimental software rendering
3. Experimental full repaint rendering
4. Antialiasing settings for text
I made them all hot reloadable by telling the `TermControl` to propagate them on settings change to the `DxEngine`.
Then I set up the `DxEngine` inside the setters to only set them if they changed. And if they do change, to trigger a full repaint and/or a complete drop and recreate of the entire DX device chain (as would happen if it were lost for another reason like a user-mode graphics failure, disconnected display, etc.)
I made the boolean an atomic because the settings can be coming in off of another thread (the XAML eventing one) and the renderer is picking the status up on its thread at the top of the BeginPaint frame.

Read the [JsonUtils Spec] for more details.
This pull request introduces the next version of JsonUtils. It is in a
separate file for ease of review and testing.
JsonUtilsNew will be renamed in a subsequent commit that rewrites our
JSON deserializers.
### Implementer's Notes
I went with telescoping exceptions for the key parsing code, because
it's totally possible that you can be five keys deep and encounter a
type error. This lets us encode information about all failures in the
chain instead of just the topmost one.
The original JsonUtilsNew code changed to use `decay` everywhere because
the tests wouldn't compile. We want to treat `GetValue<const guid>` _the
same as_ `GetValue<guid>`, and this lets us do so. `decay` is awesome.
I've been developing this with a shim that redirects `JsonUtils.h` to
`JsonUtilsNew.h`. I am not comfortable deleting the original until we've
moved off of it, and that _will_ be the subject of a followup PR.
## Validation Steps Performed
So many tests.

This commit reverts the removal of the "SSH hack" in #5383. It was
originally added as a solution to #4911, when we realized that SSH would
request the SS3 cursor key encoding but we weren't equipped to handle
it.
A number of folks have filed issues that, in summary, say "when I use
SSH, I can't select/copy/paste text". It turns out that SSH will _also_
pass through requests for mouse input. Terminal dutifully responds to
those requests, of course, by disabling mouse selection/copy/paste. SSH
is **NOT** actually in VT_INPUT_MODE, so it will never receive the mouse
messages.
It's important to note that even with #376 fixed, we are still required
to keep this check. With the closure of #376, we'll be able to convert
VT mouse input back into Win32 mouse input for Win32 applications . . .
but SSH also doesn't know how to handle Win32 mouse input.

In addition to the below (original) description, this commit introduces
a ThrottledFunc template that can throttle _any_ function. It applies
that type to muffle updates to the scrollbar.
---
Redo #3531 but without the bug that it caused (#3622) which is why it
was reverted.
I'm sorry if I explain this badly. If you don't understand a part, make
sure to let me know and I will explain it better.
### Explanation
How it worked before: `Terminal` signals that viewport changed ->
`TermControl::_TerminalScrollPositionChanged` gets called on the
terminal thread -> it dispatches work for later to be ran the UI thread
to updates the scrollbar's values
Why it's bad:
* If we have many viewport changes, it will create a long stack of
operations to run. Instead, we should just update the scroll bar with
the most recent information that we know.
* Imagine if the rate that the work gets pushed on the UI thread is
greater than the rate that it can handle: it might freeze?
* No need to be real time, we can wait just a little bit (8ms) to
accumulate viewport changes before we actually change the scroll bar's
value because it appears to be expensive (see perf below).
Now: `Terminal` signals that viewport changed ->
`TermControl::_TerminalScrollPositionChanged` gets called on the
terminal thread -> it tells the `ScrollBarUpdater` about a new update ->
the `ScrollBarUpdater` only runs one job (I don't know if that's the
right term) on the UI thread at a time. If a job is already running but
hasn't updated the scroll bar yet, it changes the setting in the already
existing job to update the scroll bar with the new values. A job "waits"
some time before doing the update to throttle updates because we don't
need real time scroll bar updates. -> eventually, it updates the scroll
bar If the user scrolls when a scroll bar update is pending, we keep the
scroll bar's Maximum and Minimum but let the user choose its new Value
with the `CancelPendingValueChange` method.
### Note
Also I changed a little bit the code from the Terminal to notify the
TermControl less often when possible.
I tried to scroll with the scroll bar, with the mouse wheel. I tried to
scroll while content is being outputted.
I tried to reproduce the crash from #2248 without success (good).

For mysterious reasons lost to the sands of time, XAML will _never_ pass
us a VK_MENU event. This is something that'll probably get fixed in
WinUI 3, but considering we're stuck on system XAML for the time being,
the only way to work around this bug is to pass the event through

event" handler that uses the same focus and tunneling method to send
different key events, and then uses it to send VK_MENU.

* [wpf] WM_KEYUP crashes on x64 #6444
- Turns out that doing the `(uint)lParam` cast worked fine for the
keydowns, because the value of lParam usually didn't have super
high-order bits set. That's not the case for keyups, where the 30th
bit is _always_ set. This is fixed by explicitly getting the byte
with the scancode in it.
* [wpf] WM_KEYUP generates wrong value in Win32 input mode #6445
- This was fixed by basically the same thing as the above.
* [wpf] WPF control crashes on startup trying to render cursor #6446
- This was a regression from #6337. I forgot to initialize the brush
used to paint the cursor, because the UWP version always uses color
(but the WPF one relies on the text foreground color).
* Also adds a minor change to the WPF test app, so that the user can
actually exit `win32-input-mode`.

## Detailed Description of the Pull Request / Additional comments
Two fixes:
1. For outputting lots of text, the base renderer class spent a lot of time allocating and freeing and reallocating the `Cluster` vector that adapts the text buffer information into render clusters. I've now cached this vector in the base render class itself and I shrink/grow it based on the viewport update that happens at the top of every frame. To prevent too much thrashing in the downward/shrink direction, I wrote the `til::manage_vector` helper that contains a threshold to only shrink if it asks for small enough of a size relative to the existing one. I used 80% of the existing size as the threshold for this one.
2. For outputting lots of changing colors, the VT graphics output engine spent a bunch of time allocating and reallocating the vector for `GraphicsOptions`. This one doesn't really have a predictable size, but I never expect it to get extremely big. So I just held it in the base class.

This pull request moves WindowUiaProvider back into Win32 interactivity
and deletes all mention of it from Windows Terminal. Terminal does not
have a single toplevel window that requires Console-like UIA, as each
Xaml control inside it is in charge of its own destiny.
I've also merged `IUiaWindow` and `IConsoleWindow` back together, as
well as `WindowUiaProviderBase` and `WindowUiaProvider`.
Things look a lot more like they did before we tore them apart.

* Tried to repro this in the Terminal, couldn't anymore.
When opening a new tab, it takes a few milliseconds before title to
appears. This PR makes it instantaneous.
* Updated the Terminal so that it can load the title from the settings
before it is initialized.
* Load terminal settings in TermControl constructor before the terminal
is initialized (see above).
* Update Tab so that it sets the TabViewItem's title in the constructor
(in Tab::_MakeTabViewItem) instead of waiting for the VT sequence to
set the title (from what I understand).
NOTE 1: there is a similar problem with the tabview icon which is not
fixed by this PR.
NOTE 2: This is only a problem with animations disabled because
otherwise the title fades in so there is enough time for it to be set
when it becomes visible.
## Validation
I ran the terminal and opened a new tab. The title appears instantly.
This commit introduces a new project that lets you F5 a working instance
of the Wpf Terminal Control.
To make the experience as seamless as possible, I've introduced another

projects for "Any CPU" and every project that PublicTerminalCore
requires (including itself) for "x64". This is the only way to ensure
that when you press F5, all of the native and managed dependencies get
updated.
It's all quite cool when it works.

Adds support for `win32-input-mode` to conhost, conpty, and the Windows
Terminal.
* The shared `terminalInput` class supports sending these sequences when
a VT client application requests this mode.
* ConPTY supports synthesizing `INPUT_RECORD`s from the input sent to it

* ConPTY requests this mode immediately on startup (if started with a
new flag, `PSEUDOCONSOLE_WIN32_INPUT_MODE`)
* The Terminal now supports sending this input as well, when conpty asks
for it.
Also adds a new ConPTY flag `PSEUDOCONSOLE_WIN32_INPUT_MODE` which
requests this functionality from conpty, and the Terminal requests this
by default.
Also adds `experimental.input.forceVT` as a global setting to let a user
opt-out of this behavior, if they don't want it / this ends up breaking
horribly.

Wildcards are not allowed in toplevel ItemGroups in vcxproj; they must
be generated by targets.
We mostly use wildcards for pulling in PRI files that are dumped on disk
by the translation tool. We don't want to check those in, so we can't
expand references to them.
To that end, I've introduced a new target that will take a list of
folders containing resw files and expand wildcards under them.
All[1] other wildcards have been moved into their respective targets
_or_ simply expanded.
[1]: Nothing has complained about the resource wildcards in
CascadiaResources.build.items, so I haven't exploded it yet.
Fixes#6214.
This PR provides a faster algorithm for converting 8-bit and 24-bit
colors into the 4-bit legacy values that are required by the Win32
console APIs. It also fixes areas of the code that were incorrectly
using a simple 16-color conversion that didn't handle 8-bit and 24-bit
values.
The faster conversion algorithm should be an improvement for issues #783
and #3950.
One of the main points of this PR was to fix the
`ReadConsoleOutputAttribute` API, which was using a simplified legacy
color conversion (the original `TextAttribute:GetLegacyAttributes`
method), which could only handle values from the 16-color table. RGB
values, and colors from the 256-color table, would be mapped to
completely nonsensical values. This API has now been updated to use the
more correct `Settings::GenerateLegacyAttributes` method.
But there were also a couple of other places in the code that were using
`GetLegacyAttributes` when they really had no reason to be working with
legacy attributes at all. This could result in colors being downgraded
to 4-bit values (often badly, as explained above), when the code was
already perfectly capable of displaying the full 24-bits.
This included the fill colors in the IME composer (in `ConsoleImeInfo`),
and the construction of the highlighting colors in the color
search/selection handler (`Selection::_HandleColorSelection`). I also
got rid of some legacy attribute code in the `Popup` class, which was
originally intended to update colors below the popup when the settings
changed, but actually caused more problems than it solved.
The other major goal of this PR was to improve the performance of the
`GenerateLegacyAttributes` method, since the existing implementation
could be quite slow when dealing with RGB values.
The simple cases are handled much the same as they were before. For an
`IsDefault` color, we get the default index from the
`Settings::_wFillAttribute` field. For an `IsIndex16` color, the index
can just be returned as is.
For an `IsRgb` color, the RGB components are compressed down to 8 bits
(3 red, 3 green, 2 blue), simply by dropping the least significant bits.
This 8-bit value is then used to lookup a representative 16-color value
from a hard-coded table. An `IsIndex256` color is also converted with a
lookup table, just using the existing 8-bit index.
The RGB mapping table was calculated by taking each compressed 8-bit
color, and picking a entry from the _Campbell_ palette that best
approximated that color. This was done by looking at a range of 24-bit
colors that mapped to the 8-bit value, finding the best _Campbell_ match
for each of them (using a [CIEDE2000] color difference calculation), and
then the most common match became the index that the 8-bit value would
map to.
The 256-color table was just a simpler version of this process. For each
entry in the table, we take the default RGB palette value, and find it's
closest match in the _Campbell_ palette.
Because these tables are hard-coded, the results won't adjust to changes
in the palette. However, they should still produce reasonable results
for palettes that follow the standard ANSI color range. And since
they're only a very loose approximation of the colors anyway, the exact
value really isn't that important.
That said, I have tried to make sure that if you take an RGB value for a
particular index in a reasonable color scheme, then the legacy color
mapped from that value should ideally match the same index. This will
never be possible for all color schemes, but I have tweaked a few of the
table entries to improve the results for some of the common schemes.
One other point worth making regarding the hard-coded tables: even if we
wanted to take the active palette into account, that wouldn't actually
be possible over a conpty connection, because we can't easily know what
color scheme the client application is using. At least this way the
results in conhost are guaranteed to be the same as in the Windows
Terminal.
[CIEDE2000]: https://en.wikipedia.org/wiki/Color_difference#CIEDE2000
## Validation Steps Performed
This code still passes the `TextAttributeTests` that check the basic
`GetLegacyAttribute` behaviour and verify the all legacy attributes
roundtrip correctly. However, some of the values in the `RgbColorTests`
had to be updated, since we're now intentionally returning different
values as a result of the changes to the RGB conversion algorithm.
I haven't added additional unit tests, but I have done a lot of manual
testing to see how well the new algorithm works with a range of colors
and a variety of different color schemes. It's not perfect in every
situation, but I think it works well enough for the purpose it serves.
I've also confirmed that the issues reported in #5940 and #6247 are now
fixed by these changes.
Closes#5940Closes#6247
In Windows, we build with /Zc:wchar_t- (which makes wchar_t an unsigned
short typedef.) This causes build breaks when we compare two wchar_t
values (or a wchar_t and an enum class that's of type wchar_t) and the
compiler decides that it might want to _promote them to TextAttribute_
before doing the comparison.
## Summary of the Pull Request
When we select a color for the tab, we update the foreground color of the text so that it maintains acceptable contrast with the new tab color. However, we weren't also updating the foreground color of the close button.
This is understandable though, because apparently this wasn't fixable until MUX 2.4 arrived. I'm not a XAML expert, but I know that setting this key only works when we're using MUX 2.4, so I'm assuming something about the TabView implementation changed in that release. _This PR is marked as a draft until #5778 is merged, then I'll re-target to master._

This PR improves our VT character set support, enabling the [`SCS`]
escape sequences to designate into all four G-sets with both 94- and
96-character sets, and supports invoking those G-sets into both the GL
and GR areas of the code table, with [locking shifts] and [single
shifts]. It also adds [`DOCS`] sequences to switch between UTF-8 and the
ISO-2022 coding system (which is what the VT character sets require),
and adds support for a lot more characters sets, up to around the level
of a VT510.

## Detailed Description of the Pull Request / Additional comments
To make it easier for us to declare a bunch of character sets, I've made
a little `constexpr` class that can build up a mapping table from a base
character set (ASCII or Latin1), along with a collection of mappings for
the characters the deviate from the base set. Many of the character sets
are simple variations of ASCII, so they're easy to define this way.
This class then casts directly to a `wstring_view` which is how the
translation tables are represented in most of the code. We have an array
of four of these tables representing the four G-sets, two instances for
the active left and right tables, and one instance for the single shift
table.
Initially we had just one `DesignateCharset` method, which could select
the active character set. We now have two designate methods (for 94- and
96- character sets), and each takes a G-set number specifying the target
of the designation, and a pair of characters identifying the character
set that will be designated (at the higher VT levels, character sets are
often identified by more than one character).
There are then two new `LockingShift` methods to invoke these G-sets
into either the GL or GR area of the code table, and a `SingleShift`
method which invokes a G-set temporarily (for just the next character
that is output).
I should mention here that I had to make some changes to the state
machine to make these single shift sequences work. The problem is that
the input state machine treats `SS3` as the start of a control sequence,
while the output state machine needs it to be dispatched immediately
(it's literally the _Single Shift 3_ escape sequence). To make that
work, I've added a `ParseControlSequenceAfterSs3` callback in the
`IStateMachineEngine` interface to decide which behavior is appropriate.
When it comes to mapping a character, it's simply an array reference
into the appropriate `wstring_view` table. If the single shift table is
set, that takes preference. Otherwise the GL table is used for
characters in the range 0x20 to 0x7F, and the GR table for characters
0xA0 to 0xFF (technically some character sets will only map up to 0x7E
and 0xFE, but that's easily controlled by the length of the
`wstring_view`).
The `DEL` character is a bit of a special case. By default it's meant to
be ignored like the `NUL` character (it's essentially a time-fill
character). However, it's possible that it could be remapped to a
printable character in a 96-character set, so we need to check for that
after the translation. This is handled in the `AdaptDispatch::Print`
method, so it doesn't interfere with the primary `PrintString` code
path.
The biggest problem with this whole process, though, is that the GR
mappings only really make sense if you have access to the raw output,
but by the time the output gets to us, it would already have been
translated to Unicode by the active code page. And in the case of UTF-8,
the characters we eventually receive may originally have been composed
from two or more code points.
The way I've dealt with this was to disable the GR translations by
default, and then added support for a pair of ISO-2022 `DOCS` sequences,
which can switch the code page between UTF-8 and ISO-8859-1. When the
code page is ISO-8859-1, we're essentially receiving the raw output
bytes, so it's safe to enable the GR translations. This is not strictly
correct ISO-2022 behavior, and there are edge cases where it's not going
to work, but it's the best solution I could come up with.
## Validation Steps Performed
As a result of the `SS3` changes in the state machine engine, I've had
to move the existing `SS3` tests from the `OutputEngineTest` to the
`InputEngineTest`, otherwise they would now fail (technically they
should never have been output tests).
I've added no additional unit tests, but I have done a lot of manual
testing, and made sure we passed all the character set tests in Vttest
(at least for the character sets we currently support). Note that this
required a slightly hacked version of the app, since by default it
doesn't expose a lot of the test to low-level terminals, and we
currently identify as a VT100.

## Summary of the Pull Request
This is the plan that @miniksa suggested to me. Instead of trying to do lots of work in all the renderers to do backgrounds as one pass, and foregrounds as another, we can localize this change to basically just the DX renderer.
1. First, we give the DX engine a "heads up" on where the cursor is going to be drawn during the frame, in `PrepareRenderInfo`.
- This function is left unimplemented in the other render engines.
2. While printing runs of text, the DX renderer will try to paint the cursor in `CustomTextRenderer::DrawGlyphRun` INSTEAD of `DxEngine::PaintCursor`. This lets us weave the cursor background between the text background and the text.

## Detailed Description of the Pull Request / Additional comments
* I had to move the commandline arg parsing up a layer from `TerminalPage` to `AppLogic`, because `AppLogic` controls the Terminal's settings, including launch mode settings. This seems like a reasonable change, to put both the settings from the file and the commandline in the same place.

## Detailed Description of the Pull Request / Additional comments
Most of the work involves updates to the parsing state machine, which behaves differently in VT52 mode. `CSI`, `OSC`, and `SS3` sequences are not applicable, and there is one special-case escape sequence (_Direct Cursor Address_), which requires an additional state to handle parameters that come _after_ the final character.
Once the parsing is handled though, it's mostly just a matter of dispatching the commands to existing methods in the `ITermDispatch` interface. Only one new method was required in the interface to handle the _Identify_ command.
The only real new functionality is in the `TerminalInput` class, which needs to generate different escape sequences for certain keys in VT52 mode. This does not yet support _all_ of the VT52 key sequences, because the VT100 support is itself not yet complete. But the basics are in place, and I think the rest is best left for a follow-up issue, and potentially a refactor of the `TerminalInput` class.
I should point out that the original spec called for a new _Graphic Mode_ character set, but I've since discovered that the VT terminals that _emulate_ VT52 just use the existing VT100 _Special Graphics_ set, so that is really what we should be doing too. We can always consider adding the VT52 graphic set as a option later, if there is demand for strict VT52 compatibility.
## Validation Steps Performed
I've added state machine and adapter tests to confirm that the `DECANM` mode changing sequences are correctly dispatched and forwarded to the `ConGetSet` handler. I've also added state machine tests that confirm the VT52 escape sequences are dispatched correctly when the ANSI mode is reset.
For fuzzing support, I've extended the VT command fuzzer to generate the different kinds of VT52 sequences, as well as mode change sequences to switch between the ANSI and VT52 modes.
In terms of manual testing, I've confirmed that the _Test of VT52 mode_ in Vttest now works as expected.

## Summary of the Pull Request
This looks like a big diff, but there's a bunch of existing code that
just got moved around, and there's a cool new Utils template.
The tests all pass, and this passed manual validation. I tried weird
things like "making a profile named `{ }`"
(w/ enough spaces to look like a guid), and yeah it doesn't let you
specify that one as a name, but _why would you do that?!_
Okay, this pull request abstracts the conversion of a profile name into
an optional profile guid out of the "New Terminal Tab Args" handler and
into a common space for all of CascadiaSettings to use.
It also cleans up the conversion of indices and names into optional
GUIDs and turns _those_ into further helpers.
It also introduces a cool new template for running value_or multiple
times on a chain of optionals. CoalesceOptionals is a "choose first,
with fallback" for N>1 optionals.
On top of all this, I've built support for an "unparsed default GUID":
we load the user's defaultProfile as a string, and as part of settings
validation we unpack that string using the helpers outlined above.

## Detailed Description of the Pull Request / Additional comments
Please note, I'm a non-practicing C++ developer, there are a number of things I wasn't sure how to handle in the appropriate fashion, mostly around error handling and what probably looks like an incredibly naive (and messy) way to implement the async co_await behavior.
Error handling-wise, I found (don't ask me how!) that if you somehow mismatch the startup task's ID between the manifest and the call to `StartupTask::GetAsync(hstring taskId)`, you'll get a very opaque WinRT exception that boils down to a generic invalid argument message. This isn't likely to happen in the wild, but worth mentioning...
I had enough trouble getting myself familiarized with the project, environment, and C++/WinRT in general didn't want to try to tackle adding tests for this quite yet since (as I mentioned) I don't really know what I'm doing. I'm happy to give it a try with perhaps a bit of assistance in getting started 😃
Further work in this area of the application outside of this immediate PR might need to include adding an additional setting to contain launch args that the startup task can pass to the app so that users can specify a non-default profile to launch on start, window position (e.g., #653).
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
✔️ Default settings:
Given the user does not have the `startOnUserLogin` setting in their profile.json,
When the default settings are opened (via alt+click on Settings),
Then the global settings should contain the `"startOnUserLogin": false` token
✔️ Applying setting on application launch
Given the `startOnUserLogin` is `true` and
the `Windows Terminal` startup task is `disabled` and
the application is not running
When the application is launched
Then the `Windows Terminal` entry in the user's Startup list should be `enabled`
✔️ Applying setting on settings change
Given the `startOnUserLogin` is `true` and
the `Windows Terminal` startup task is `enabled` and
the application is running
When the `startOnUserLogin` setting is changed to `false` and
the settings file is saved to disk
Then the `Windows Terminal` startup task entry should be `disabled`
✔️ Setting is ignored when user has manually disabled startup
Given the `startOnUserLogin` is `true` and
the application is not running and
the `Windows Terminal` startup task has been set to `disabled` via user action
When the application is launched
Then the startup task should remain disabled and
the application should not throw an exception
#### note: Task Manager does not seem to re-scan startup task states after launch; the Settings -> Apps -> Startup page also requires closing or moving away to refresh the status of entries
Implements what I was suggesting in #6266 where if a shortcut doesn't
specify an icon, the shortcut target full path is used before searching
for a matching executable in the path.
## References
Found due to not getting the right icon in conhost from the Yori
installer. It's fixed in the installer from
5af366b6a5
for all current users of conhost though, so this PR is just trying to
minimize surprises for the next guy.
## Detailed Description of the Pull Request / Additional comments
I know conhost and shortcut settings aren't really the team's focus
which is why I'm doing this. I understand though if there's a better
way or there are factors that I hadn't considered. Note that the path
searching code is used when programs are launched without using a
shortcut, and it will match if the working directory of the shortcut is
the directory containing the executable.
## Validation Steps Performed
Created a shortcut that didn't specify an icon to a binary that wasn't
in the path, and verified that the icon in the upper left of the console
window could resolve correctly when opening the shortcut. I'm not aware
of a way to get into this path (of launching via a shortcut to a command
line process) without replacing the system conhost, which is what I did
to verify it. In order to diagnose it, I used hardcoded DebugBreak()
since even ImageFileExecutionOptions didn't like running against conhost-
is there are better way to debug and test these cases without being so
invasive on the system?
Closes#6266
For a radio button group to work properly, they need sequential IDs.
This moves the cursor radio buttons on the `conhost` property sheet to
be sequential.

## Detailed Description of the Pull Request / Additional comments
- `CheckRadioButton` takes a contiguous group of IDs. It will set one
item in the list and then uncheck the rest. When a new one was added
to the group, it was added to the end of the segment in the IDs file,
but not immediately after the existing radio buttons. This means it
accidentally turned off all the other buttons in the middle.
- To resolve this, I moved all the cursor buttons into their own
sequential group number and I deprecated the old values.
## Validation Steps Performed
- [x] Ensured that the "Discard Old Duplicates" value was set in the
registry, walked through debugger as `conhost` packed the `TRUE` value
into the property sheet blob, walked through the property sheet
`console.dll` as it unpacked the `TRUE`, then observed that the
checkbox was actually set instead of getting unset by the
`CheckRadioButton` call that went from 107 to 119 and accidentally
unchecked number 112, `IDD_HISTORY_NODUP` even though I swear it was
just set.

It's important to let the winow get created, _then_ fullscreen it, because otherwise, when the user exits fullscreen, the window is sized to like, 0x0 or something, and that's just annoying.
This PR introduces a new `ColorType` to allow us to distinguish between
`SGR` indexed colors from the 16 color table, the lower half of which
can be brightened, and the ISO/ITU indexed colors from the 256 color
table, which have a fixed brightness. Retaining the distinction between
these two types will enable us to forward the correct `SGR` sequences to
conpty when addressing issue #2661.
The other benefit of retaining the color index (which we didn't
previously do for ISO/ITU colors) is that it ensures that the colors are
updated correctly when the color scheme is changed.

## Detailed Description of the Pull Request / Additional comments
The first part of this PR was the introduction of a new `ColorType` in
the `TextColor` class. Instead of just the one `IsIndex` type, there is
now an `IsIndex16` and an `IsIndex256`. `IsIndex16` covers the eight
original ANSI colors set with `SGR 3x` and `SGR 4x`, as well as the
brighter aixterm variants set with `SGR 9x` and `SGR 10x`. `IsIndex256`
covers the 256 ISO/ITU indexed colors set with `SGR 38;5` and `SGR
48;5`.
There are two reasons for this distinction. The first is that the ANSI
colors have the potential to be brightened by the `SGR 1` bold
attribute, while the ISO/ITO color do not. The second reason is that
when forwarding an attributes through conpty, we want to try and
preserve the original SGR sequence that generated each color (to the
extent that that is possible). By having the two separate types, we can
map the `IsIndex16` colors back to ANSI/aixterm values, and `IsIndex256`
to the ISO/ITU sequences.
In addition to the VT colors, we also have to deal with the legacy
colors set by the Windows console APIs, but we don't really need a
separate type for those. It seemed most appropriate to me to store them
as `IsIndex256` colors, since it doesn't make sense to have them
brightened by the `SGR 1` attribute (which is what would happen if they
were stored as `IsIndex16`). If a console app wanted a bright color it
would have selected one, so we shouldn't be messing with that choice.
The second part of the PR was the unification of the two color tables.
Originally we had a 16 color table for the legacy colors, and a separate
table for the 256 ISO/ITU colors. These have now been merged into one,
so color table lookups no longer need to decide which of the two tables
they should be referencing. I've also updated all the methods that took
a color table as a parameter to use a `basic_string_view` instead of
separate pointer and length variables, which I think makes them a lot
easier and safer to work with.
With this new architecture in place, I could now update the
`AdaptDispatch` SGR implementation to store the ISO/ITU indexed colors
as `IsIndex256` values, where before they were mapped to RGB values
(which prevented them reflecting any color scheme changes). I could also
update the `TerminalDispatch` implementation to differentiate between
the two index types, so that the `SGR 1` brightening would only be
applied to the ANSI colors.
I've also done a bit of code refactoring to try and minimise any direct
access to the color tables, getting rid of a lot of places that were
copying tables with `memmove` operations. I'm hoping this will make it
easier for us to update the code in the future if we want to reorder the
table entries (which is likely a requirement for unifying the
`AdaptDispatch` and `TerminalDispatch` implementations).
## Validation Steps Performed
For testing, I've just updated the existing unit tests to account for
the API changes. The `TextColorTests` required an extra parameter
specifying the index type when setting an index. And the `AdapterTest`
and `ScreenBufferTests` required the use of the new `SetIndexedXXX`
methods in order to be explicit about the index type, instead of relying
on the `TextAttribute` constructor and the old `SetForeground` and
`SetBackground` methods which didn't have a way to differentiate index
types.
I've manually tested the various console APIs
(`SetConsoleTextAttribute`, `ReadConsoleOutputAttribute`, and
`ReadConsoleOutput`), to make sure they are still setting and reading
the attributes as well as they used to. And I've tested the
`SetConsoleScreenBufferInfoEx` and `GetConsoleScreenBufferInfoEx` APIs
to make sure they can read and write the color table correctly. I've
also tested the color table in the properties dialog, made sure it was
saved and restored from the registry correctly, and similarly saved and
restored from a shortcut link.
Note that there are still a bunch of issues with the color table APIs,
but no new problems have been introduced by the changes in this PR, as
far as I could tell.
I've also done a bunch of manual tests of `OSC 4` to make sure it's
updating all the colors correctly (at least in conhost), and confirmed
that the test case in issue #1223 now works as expected.
This is mostly a codehealth thing - we made these handy macros for just defining basic `{ get; set; }` properties, but we never used them in TerminalSettings, because that file was written before the macros were.
This cleans up that class.

## Summary of the Pull Request
When using an _Input Method Editor_ in conhost for East Asian languages, the text cursor is temporarily hidden while the characters are being composed. When the composition is complete, the cursor visibility is meant to be restored, but that doesn't always happen if the IME composition is cancelled. This PR makes sure the cursor visibility is always restored, regardless of how the IME is closed.

## Detailed Description of the Pull Request / Additional comments
The original implementation hid the cursor whenever `ConsoleImeInfo::WriteCompMessage` was called (which could be multiple times in the course of a composition), and then only restored the visibility when `ConsoleImeInfo::WriteResultMessage` was called. If a composition is cancelled, though, `WriteResultMessage` would never be called, so the cursor visibility wouldn't be restored.
I've now made the `SaveCursorVisibility` and `RestoreCursorVisibility` methods public, so they can instead be called from the `ImeStartComposition` and `ImeEndComposition` functions. This makes sure `RestoreCursorVisibility` is always called, regardless of how the composition ended, and `SaveCursorVisibility` is only called once at the start of the composition (which isn't essential, but seems cleaner to me).
## Validation Steps Performed
I've manually tested opening and closing the IME, both while submitting characters and while cancelling a composition, and in all cases the cursor visibility was correctly restored.
## Summary of the Pull Request

## Detailed Description of the Pull Request / Additional comments
I tried for a couple hours this morning to do this as a `VisualState`. First I tried doing it as one on the TabRow, which I had very little success with. Then, I eventually realized that the TabRow wasn't even responsible for the padding there, it was being created by the fact that the caption buttons were too tall. Again, I tried to use the existing `VisualState`s they have defined for this, but I couldn't figure out how to do that.
I think the visual state solution would be _cleaner_, so if someone knows how to do that instead, please let me know.

There is a range of 216 colors in the default 256-color table that is
meant to be initialized with a 6x6x6 color cube, with each color
component iterating over the values `00`, `5F`, `87`, `AF`, `D7`, and
`FF`. A few of the entries incorrectly had the _red_ component has `DF`,
when it should have been `D7`. This PR corrects those entries. It also
removes a bit of unnecessary whitespace in the first 100 entries.
## Validation Steps Performed
I have a visual test script that renders the full 256-color palette,
using both the indexed color sequence (`SGR 38;5`) and the equivalent
rgb representation (`SGR 38;2`) side by side. Although the difference
was subtle when it was incorrect, I can now see that it has been fixed.
Closes#5994
This removes all glyphs from the emoji list that do not default to
"emoji presentation" (EPres). It removes all local overrides, but retains
the comments about the emoji we left out that are Microsoft-specific.
This brings us fully in line with the most popular Terminals on OS X,
except that we squash our emoji down to fit in one cell and they let
them hang over the edges and damage other characters. Oh well.
## Detailed Description of the Pull Request / Additional comments
Late Friday evening, I tested my emoji test file on iTerm2. In so doing, I realized
that @j4james and @leonMSFT were right the entire time in #5914: Emoji
that require `U+FE0F` must not be double-width by default.
I finally banged up a powershell script that parses the UCD and emits a codepoint
width table. Once checked in, this will be definitive.
Refs #900, #5914.
Fixes#5941.
This pull request moves swaths of Cascadia to use `til::color` for color
interop. There are still some places where we use `COLORREF`, such as in
the ABI boundaries between WinRT components.
I've also added two more til::color helpers - `with_alpha`, which takes
an existing color and sets its alpha component, and a
`Windows::UI::Color` convertor pair.
Future direction might include a `TerminalSettings::Color` type at the
idl boundary so we can finally stop using UInt32s (!) for color.
## Validation Steps Performed
Tested certain fragile areas:
* [x] setting the background with OSC 11
* [x] setting the background when acrylic is in use (which requires
low-alpha)
The AKB serializer is used in the tracelogging pipeline.
Chatted with @zadjii-msft about ganking the deserializers. The form
they'll take in the future is probably very different from this.
We'll need to have some better tracking of the _source_ or _pass_ a
setting was read during so that we can accurately construct an internal
settings attribution model. Diffing was very extremely cool, but we
didn't end up needing it.
This apparently drops our binary size by a whopping _zero bytes_ because
the optimizer was smarter than us and actually totally deleted it.
This seems to be in line with the emoji-sequences table in the latest
version of the Unicode standard: those glyphs require U+FE0F to activate
their emoji presentation. Since we don't support composing U+FE0F, we
should not present them as emoji by default.
Fixes#5910.
Yes, I hate this.
My workflow is to use Sublime's <kbd>Ctrl+P</kbd> shortcut to navigate to files by name. However, the propsheet version of the files _always_ comes up before the `TerminalApp` one does. This results in me having to close the file and re-open the right one.
This PR renames the propsheet one, so it's unambiguous which one I'm opening.
It's really the most trivial nit.
