Instead of having a separate method for setting each mouse and keyboard
mode, this PR consolidates them all into a single method which takes a
mode parameter, and stores the modes in a `til::enumset` rather than
having a separate `bool` for each mode.
This enables us to get rid of a lot of boilerplate code, and makes the
code easier to extend when we want to introduce additional modes in the
future. It'll also makes it easier to read back the state of the various
modes when implementing the `DECRQM` query.
Most of the complication is in the `TerminalInput` class, which had to
be adjusted to work with an `enumset` in place of all the `bool` fields.
For the rest, it was largely a matter of replacing calls to all the old
mode setting methods with the new `SetInputMode` method, and deleting a
bunch of unused code.
One thing worth mentioning is that the `AdaptDispatch` implementation
used to have a `_ShouldPassThroughInputModeChange` method that was
called after every mode change. This code has now been moved up into the
`SetInputMode` implementation in `ConhostInternalGetSet` so it's just
handled in one place. Keeping this out of the dispatch class will also
be beneficial for sharing the implementation with `TerminalDispatch`.
## Validation
The updated interface necessitated some adjustments to the tests in
`AdapterTest` and `MouseInputTest`, but the essential structure of the
tests remains unchanged, and everything still passes.
I've also tested the keyboard and mouse modes in Vttest and confirmed
they still work at least as well as they did before (both conhost and
Windows Terminal), and I tested the alternate scroll mode manually
(conhost only).
Simplifying the `ConGetSet` and `ITerminalApi` is also part of the plan
to de-duplicate the `AdaptDispatch` and `TerminalDispatch`
implementation (#3849).
## Summary of the Pull Request
When we parse OSC 9;4, allow a trailing semicolon (i.e. allow `9;4;` or something like `9;4;3;`).
## PR Checklist

* [X] Tests added/passed
## Validation Steps Performed
OSC 9;4 sequences with or without trailing semicolons work
Implement the `XTPUSHSGR` and `XTPOPSGR` control sequences (see #1796).
This change adds a new pair of methods to `ITermDispatch`:
`PushGraphicsRendition` and `PopGraphicsRendition`, and then plumbs the
change through `AdaptDispatch`, `TerminalDispatch`, `ITerminalApi` and
`TerminalApi`.
The stack logic is encapsulated in the `SgrStack` class, to allow it to
be reused between the two APIs (`AdaptDispatch` and `TerminalDispatch`).
Like xterm, only ten levels of nesting are supported.
The stack is implemented as a "ring stack": if you push when the stack
is full, the bottom of the stack will be dropped to make room.
Partial pushes (see the description of `XTPUSHSGR` in Issue #1796) are
implemented per xterm spec.
## Validation Steps Performed
Tests added, plus manual verification of the feature.
Closes#1796
This adds the skeleton code for "bracketed paste mode" to the Windows
Terminal. No actual functionality is implemented yet, just the wiring
for handling DECSET/DECRST 2004.

## Validation Steps Performed
This commit implements the OSC 9;4 sequence per the [ConEmu style].
| sequence | description |
| ------------ | ------------ |
| `ESC ] 9 ; 4 ; st ; pr ST` | Set progress state on taskbar and tab. |
| | When `st` is: |
| | |
| | `0`: remove progress. |
| | `1`: set progress value to `pr` (number, 0-100). |
| | `2`: set the taskbar to the "Error" state |
| | `3`: set the taskbar to the "Indeterminate" state |
| | `4`: set the taskbar to the "Warning" state |
We've also extended this with:
* st 3: set indeterminate state
* st 4: set paused state
We handle multiple tabs sending the sequence by using the the last focused
control's taskbar state/progress.
Upon receiving the sequence in `TerminalApi`, we send an event that gets caught
by `TerminalPage`. `TerminalPage` then fires another event that gets caught by
`AppHost` and that's where we set the taskbar progress.
Closes#3004

This commit makes the Windows Terminal play an audible sound when the
`BEL` control character is output.
The `BEL` control was already being forwarded through conpty, so it was
just a matter of hooking up the `WarningBell` dispatch method to
actually play a sound. I've used the `PlaySound` API to output the sound
configured for the "Critical Stop" system event (aka _SystemHand_),
since that is the sound used in conhost.
## Validation
I've manually confirmed that the terminal produces the expected sound
when executing `echo ^G` in a cmd shell, or `printf "\a"` in a WSL bash
shell.
References:
* There is a separate issue (#1608) to deal with configuring the `BEL`
to trigger visual forms of notification.

`BEL`.

## 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
I've manually tested the `DECSCNM` functionality for Windows Terminal in Vttest, and also with some of my own test scripts.
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
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.
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
from a terminal
* 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.

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.
Adds support for setting the cursor visibility in Terminal. Visibility
is a property entirely independent from whether the cursor is "on" or
not. The cursor blinker _should_ change the "IsOn" property. It was
actually changing the "Visible" property, which was incorrect. This PR
additionally corrects the naming of the method used by the cursor
blinker, and makes it do the right thing.
I added a pair of tests, one taken straight from conhost. In
copy-pasting that test, I took it a step further and implemented
`^[[?12h`, `^[[?12l`, which enables/disables cursor blinking, for the
`TerminalCore`. THIS DOES NOT ADD SUPPORT FOR DISABLING BLINKING IN THE
APP. Conpty doesn't emit the blinking on/off sequences quite yet, but
when it _does_, the Terminal will be ready.

## Summary of the Pull Request
This PR removes all of the VT-specific functionality from the `WriteCharsLegacy` function that dealt with control characters, since those controls are now handled in the state machine when in VT mode. It also removes most of the control character handling from the `Terminal::_WriteBuffer` method for the same reason.

## Detailed Description of the Pull Request / Additional comments
There are four changes to the `WriteCharsLegacy` implementation:
1. The `TAB` character had special case handling in VT mode which is now no longer required. This fixes a bug in the Python REPL editor (when run from a cmd shell in Windows Terminal), which would prevent you tabbing past the end of the line. It also fixes#3971.
2. Following on from point 1, the `WC_NONDESTRUCTIVE_TAB` flag could also now be removed. It only ever applied in VT mode, in which case the `TAB` character isn't handled in `WriteCharsLegacy`, so there isn't a need for a non-destructive version.
3. There used to be special case handling for a `BS` character at the beginning of the line when in VT mode, and that is also no longer required. This fixes an edge-case bug which would prevent a glyph being output for code point 8 when `ENABLE_PROCESSED_OUTPUT` was disabled.
4. There was quite a lot of special case handling for control characters in the "end-of-line wrap" implementation, which is no longer required. This fixes a bug which would prevent "low ASCII" characters from wrapping when output at the end of a line.
Then in the `Terminal::_WriteBuffer` implementation, I've simply removed all control character handling, except for `LF`. The Terminal is always in VT mode, so the control characters are always handled by the state machine. The exception for the `LF` character is simply because it doesn't have a proper implementation yet, so it still passes the character through to `_WriteBuffer`. That will get cleaned up eventually, but I thought that could wait for a later PR.
Finally, with the removal of the VT mode handling in `WriteCharsLegacy`, there was no longer a need for the `SCREEN_INFORMATION::InVTMode` method to be publicly accessible. That has now been made private.
## Validation Steps Performed
I've only tested manually, making sure the conhost and Windows Terminal still basically work, and confirming that the above-mentioned bugs are fixed by these changes.

## Detailed Description of the Pull Request / Additional comments
This is in support of hopefully turning audit mode on to more projects. If I turned it on, it would immediately complain about certain classes of issues like pointer and size, pointer math, etc. The changes in this refactoring will eliminate those off the top.
Additionally, this has caught a bunch of comments all over the VT classes that weren't updated to match the parameters lists.
Additionally, this has caught a handful of member variables on classes that were completely unused (and now gone).
Additionally, I'm killing almost all hungarian and shortening variable names. I'm only really leaving 'p' for pointers.
Additionally, this is vaguely in support of a future where we can have "infinite scrollback" in that I'm moving things to size_t across the board. I know it's a bit of a memory cost, but all the casting and moving between types is error prone and unfun to save a couple bytes.
