Let's assume the user has bound the dead key ^ to a sendInput command
that sends "b". If the user presses the two keys ^a it'll produce "bâ",
despite us marking the key event as handled. We can use `ToUnicodeEx`
to clear such dead keys from the keyboard state and should make use of
that for keybindings. Unfortunately `SetKeyboardState` cannot be used
for this purpose as it doesn't clear the dead key state.
Validation
* Enabled a German keyboard layout
* Added the following two keybindings:
{ "command": { "action": "sendInput", "input": "x" }, "keys": "q" },
{ "command": { "action": "sendInput", "input": "b" }, "keys": "^" }
* Pressed the following keys → ensured that the given text is printed:
* q → x
* ´ → nothing
* a → á
* ^ → b
* a → a (previously this would print: â)
* ´ → nothing
* ^ → b
* a → a (unfortunately we cannot specifically clear only ^)
Closes#5784
Updates the GH Action and makes a small update to the README to test
changes.
A missing install step for Windows Terminal using Scoop has been added.
The versioning of Super-Linter was also switched to v3 to allow
auto-updates within the v3 series. This can be version-pinned again if a
breaking change comes later. The current updates fix some bugs and bump
the linters utilized.
## Validation Steps Performed
Validation will be shown in the build steps.

This PR adds support for the `DECREQTPARM` (Request Terminal Parameters)
escape sequence, which was originally used on the VT100 terminal to
report the serial communication parameters. Modern terminal emulators
simply hardcode the reported values for backward compatibility.
The `DECREQTPARM` sequence has one parameter, which was originally used
to tell the terminal whether it was permitted to send unsolicited
reports or not. However, since we have no reason to send an unsolicited
report, we don't need to keep track of that state, but the permission
parameter does still determine the value of the first parameter in the
response.
The response parameters are as follows:
| Parameter | Value | Meaning |
| ---------------- | ------ | ------------------------ |
| response type | 2 or 3 | unsolicited or solicited |
| parity | 1 | no parity |
| data bits | 1 | 8 bits per character |
| transmit speed | 128 | 38400 baud |
| receive speed | 128 | 38400 baud |
| clock multiplier | 1 | |
| flags | 0 | |
There is some variation in the baud rate reported by modern terminal
emulators, and 9600 baud seems to be a little more common than 38400
baud, but I thought the higher speed was probably more appropriate,
especially since that's also the value reported by XTerm.
## Validation Steps Performed
I've added a couple of adapter and output engine tests to verify that
the sequence is dispatched correctly, and the expected responses are
generated. I've also manually tested in Vttest and confirmed that we now
pass the `DECREQTPARM` test in the _Test of terminal reports_.
Closes#7852
Terminal ships with this dependency embedded, and it is not required that you install it separately. Since the link is broken, let's just remove it entirely.

## Detailed Description of the Pull Request / Additional comments
I am using SystemParametersInfo for SPI_GETDESKWALLPAPER which puts the path into a WCHAR and that is then inserted as the BackgroundImagePath.
I do not think an additional test would add value. The SPI_GETDESKTOPWALLPAPER uses the computers local wallpaper path and puts it into a WCHAR, which then I feed into BackgroundImagePath() as it's new path. I don't think there adds value in making a static path of the desktop background and testing that, given that static tests are already done for "BackgroundImage()".
## Validation Steps Performed
(Manual Validation - Test False Value)
1. Ran Terminal
2. Set setting ["backgroundImage": "<some random img path>"] under profiles->defaults
3. Verified terminal's background is not the desktops wallpaper.
(Manual Validation - Test True Value)
1. Ran Terminal
2. Set setting ["backgroundImage": "DesktopWallpaper"] under profiles->defaults
3. Verified the background image matches the desktop background image.
(Manual Validation - Multiple Tabs True Value)
1. Ran Terminal
2. Set setting ["backgroundImage": "DesktopWallpaper"] under profiles->defaults
3. Verified the background image matches the desktop background image.
4. Opened new tabs
5. Verified the background image matches the desktop background image for each tab.
For whatever reason, the super linter seems to think that any file it doesn't recognize is an EDITORCONFIG file. That means all our `cpp`, `hpp`, `h`, `resw`, `xaml`, etc files are going to get linted with different rules than the clang-format ones we already use.
This PR disables the EDITORCONFIG linter, and has a minimal change to a cpp file to ensure that it's no longer linted by the action.

This uses the templates from
https://github.com/github/super-linter/tree/master/TEMPLATES currently.
A future PR can add the necessary templates to the Windows Terminal
repository and update the source of Templates following the README.
Additionally we can add flags to explicitly choose the linters
applicable to this code base but is not necessary.
Per the README, this does not enforce any linting rules but rather
outputs the suggestions in the build step, which are to be read by the
PR submitter and Windows Terminal team to determine if they want to use
the linting rule. C++ is currently not supported (Powershell, Json,
Yaml, and Markdown will be the only things the linter checks for
currently) but we could add our own custom support if desired in
separate PR.
## Validation Steps Performed
It successfully runs. Currently only shows the yaml file itself being
linted in this PR as a test case. It will apply to new PRs once this is
merged. We can lint existing code base but would require a separate PR
and examining the code output (also requires updating the yaml file
temporarily).
Closes#7513
* Correct the behaviour of parsing `rgb:R/G/B`. It should be interpreted
as `RR/GG/BB` instead of `0R/0G/0B`
* Add support for `rgb:RRR/GGG/BBB` and `rgb:RRRR/GGGG/BBBB`. The
behaviour of 12 bit variants is to repeat the first digit at the end,
e.g. `rgb:123/456/789` becomes `rgb:1231/4564/7897`.
* Add support for `#` formats. We are following the rules of
[XParseColor] by interpreting `#RGB` as `R000G000B000`.
* Add support for XOrg app color names, which are supported by xterm, VTE
and many other terminal emulators.
* Multi-parameter OSC 4 is now supported.
* The chaining of OSC 10-12 is not yet supported. But the parameter
validation is relaxed by parsing the parameters as multi-params but
only use the first one, which means `\e]10;rgb:R/G/B;` and
`\e]10:rgb:R/G/B;invalid` will execute `OSC 10` with the first color
correctly. This fixes some of the issues mentioned in #942 but not
all of them.

This pull request introduces (a very, very stripped-down copy of) the
WIL fallback error reporter.
It emits error records, usually immediately before the application
implodes, into the event stream.
This should improve diagnosability of issues that take Terminal down,
and allow us to give out a .wprp file to gather traces from users.
## Summary of the Pull Request
This introduces a spec for (what I like to call) winrt TerminalSettings. Basically, we need to move over some of the code that resides in TerminalApp that relates to the settings model, then expose some of the settings objects as winrt objects. Doing so will allow us to access/modify settings across different project layers (a must-have for the Settings UI).

til::static_map can't be constexpr until we move to C++20.
It can't be constexpr because std::sort isn't constexpr until then.
This poses a problem: if we start using it and treating it like a map,
we'll incur a potentially high cost in static initialization in both
code size in .text and runtime.
This commit introduces presorted_static_map, which is static_map except
that it doesn't automatically sort its keys. That's the only difference.
At this point, it's just a maplike interface to a constant array of
pairs that does a binary search. It should be used for small tables that
are used infrequently enough as to not warrant their cost in code size
or initialization time. It should also be used for tables that aren't
going to be edited much by developers (like the color table in #7578.)
This PR adds support for the _blink_ graphic rendition attribute. When a
character is output with this attribute set, it "blinks" at a regular
interval, by cycling its color between the normal rendition and a dimmer
shade of that color.
The majority of the blinking mechanism is encapsulated in a new
`BlinkingState` class, which is shared between the Terminal and Conhost
implementations. This class keeps track of the position in the blinking
cycle, which determines whether characters are rendered as normal or
faint.
In Windows Terminal, the state is stored in the `Terminal` class, and in
Conhost it's stored in the `CONSOLE_INFORMATION` class. In both cases,
the `IsBlinkingFaint` method is used to determine the current blinking
rendition, and that is passed on as a parameter to the
`TextAttribute::CalculateRgbColors` method when these classes are
looking up attribute colors.
Prior to calculating the colors, the current attribute is also passed to
the `RecordBlinkingUsage` method, which keeps track of whether there are
actually any blink attributes in use. This is used to determine whether
the screen needs to be refreshed when the blinking cycle toggles between
the normal and faint renditions.
The refresh itself is handled by the `ToggleBlinkingRendition` method,
which is triggered by a timer. In Conhost this is just piggybacking on
the existing cursor blink timer, but in Windows Terminal it needs to
have its own separate timer, since the cursor timer is reset whenever a
key is pressed, which is not something we want for attribute blinking.
Although the `ToggleBlinkingRendition` is called at the same rate as the
cursor blinking, we actually only want the cells to blink at half that
frequency. We thus have a counter that cycles through four phases, and
blinking is rendered as faint for two of those four. Then every two
cycles - when the state changes - a redraw is triggered, but only if
there are actually blinking attributes in use (as previously recorded).
As mentioned earlier, the blinking frequency is based on the cursor
blink rate, so that means it'll automatically be disabled if a user has
set their cursor blink rate to none. It can also be disabled by turning
off the _Show animations in Windows_ option. In Conhost these settings
take effect immediately, but in Windows Terminal they only apply when a
new tab is opened.
This PR also adds partial support for the `SGR 6` _rapid blink_
attribute. This is not used by DEC terminals, but was defined in the
ECMA/ANSI standards. It's not widely supported, but many terminals just
it implement it as an alias for the regular `SGR 5` blink attribute, so
that's what I've done here too.
## Validation Steps Performed
I've checked the _Graphic rendition test pattern_ in Vttest, and
compared our representation of the blink attribute to that of an actual
DEC VT220 terminal as seen on [YouTube]. With the right color scheme
it's a reasonably close match.
[YouTube]: https://www.youtube.com/watch?v=03Pz5AmxbE4&t=1m55sCloses#7388
Some IME implementations do not produce composition strings, and their
users have come to rely on the cursor that conhost traditionally left on
until a composition string showed up. We shouldn't hide the cursor until
we get a string (as opposed to hiding it when composition begins) so as
to not break those IMEs.

Add `ToJson()` to the `ConversionTrait`s in JsonUtils. This can be used

C1 control characters are now first converted to their 7 bit equivalent.
This allows us to unify the logic of C1 and C0 escape handling. This
also adds support for SOS/PM/APC string.
* Unify the logic for C1 and C0 escape handling by converting C1 to C0
beforehand. This adds support for various C1 characters, including
IND(8/4), NEL(8/5), HTS(8/8), RI(8/13), SS2(8/14), SS3(8/15),
OSC(9/13), etc.
* Add support for SOS/PM/APC escape sequences. Fixes#7032
* Use "Variable Length String" logic to unify the string termination
handling of OSC, DCS and SOS/PM/APC. This fixes an issue where OSC
action is successfully dispatched even when terminated with non-ST
character. Introduced by #6328, the DCS PassThrough is spared from
this issue. This PR puts them together and add test cases for them.

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.
x86_64 msvc | O0 | O1 | O2
------------|----|----|--------------------
shifts | 12 | 11 | 11 (fully inlined)
union | 5 | 1 | 1 (fully inlined)

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.
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.
Fixes#1637.
This commit introduces Jumplist customization and an item for each

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.
As the title suggests, this commit adds initial support for the VT DCS

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

Yes, the numbers are wrong. No, it doesn't really matter.
Consecutive RTL GlyphRuns are drawn from the last to the first.

#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.
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 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
before/after.
By default, the memory order on atomics is `seq_cst`. This is a relatively expensive ordering and it shows in situations where we're rapidly signaling a consumer to pick up something from a producer. I've instead attempted to switch these to `release` (producer) and `acquire` (consumer) to improve the performance of these signals.
## Validation Steps Performed
- Run `time cat big.txt` and `time cat ls.txt` under VS Performance Profiler.

## 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.
This commit adds image assets for High Contrast mode
Tagging this issue so it contains a nice list of all the recent HC
fixes: #5360
I made several changes to DHowett's script and added it to the repo:
* Add support for generating high contrast icons
* Add the ability to easily edit the "intermediate" (previously "zbase")
files for manual hinting
* Appease the spellchecker
I created new SVGs for HC mode. There's one SVG for both Black and White
modes -- I just invert the colors. Then I manually hinted the generated
bitmaps for the production icons. I didn't bother hinting the Dev/Pre
ones, so the text does get unreadable at small sizes.

Closes#6822
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 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
## 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_.
`showTabsInTitlebar` | Preview
-- | --
`true` | 
`false` |

## Detailed Description of the Pull Request / Additional comments
* **KNOWN ISSUE**: Upon resizing the NCIW, the top frame margin disappears, making that border disappear entirely. 6356aaf has a bunch of WIP work for me trying to fix that, but I couldn't get it quite right.
## Validation Steps Performed
* Toggled between focus and fullscreen a _bunch_ in both modes.
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
## 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.

## Summary of the Pull Request
This proposes a change to how Terminal will scroll in response to newly
generated output. The Terminal will scroll upon receiving new output if
the viewport is at the bottom of the scroll history and no selection is
active.
This spec also explores the possibility of making this response
configurable with a `snapOnOutput` profile setting. It also discusses
the possibility of adding a scroll lock keybinding action.

## 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.
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
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
# Base64 encoded `foo`
$ echo -en "\e]52;;Zm9v\a"
# Multiple lines
# Base64 encoded `foo\r\nbar`
$ echo -en "\e]52;;Zm9vDQpiYXI=\a"
Closes#2946.
## Summary of the Pull Request
Adds a pair of `ShortcutAction`s for setting the tab color.
* `setTabColor`: This changes the color of the current tab to the provided color, or can be used to clear the color.
* `openTabColorPicker`: This keybinding immediately activates the tab color picker for the currently focused tab.

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.
