This is by no means comprehensive. It will be unmarked as draft when it
is more comprehensive.
This pull request adds some tests for resizing a TextBuffer and
reflowing its contents. Each test takes the form of an initial state and
a number of buffers of different sizes. The initial state is used to
seed the first TextBuffer, and the subsequent buffers are only used to
compare.
I manually reimplemented some of the DBCS logic to ensure that the
buffers contain _exactly_ what they're supposed to. I know this is
non-ideal. After some of the CharRow changes in #8446 land, this will
need to be updated.
There's a cool bit of TAEF gore in here: the IDataSource. An IDataSource
allows us to programmatically return test cases. It's a code-only
version of its support for parameterized tests of the form `Data:x = {0,
1, 2}` .
The only downsides are...
1. It looks like COM (it is not using COM under the hood, just the COM
ABI)
2. Property values must be returned as strings.
To best support rich test types, I used IDataSource to produce _a lit of
array indices_ and nothing more. The test is run once for array member,
and it is the test's responsibility to look up the object to which that
index refers.
Works great though! Each reflow test is its own unit, and a failure in
an earlier reflow test will not tank a later one.
Adds a `Microsoft.Terminal.Remoting.dll` to our solution. This DLL will
be responsible for all the Monarch/Peasant work that's been described in
#7240 & #8135.
This PR does _not_ implement the Monarch/Peasant architecture in any
significant way. The goal of this PR is to just to establish the project
layout, and the most basic connections. This should make reviewing the
actual meat of the implementation (in a later PR) easier. It will also
give us the opportunity to include some of the basic weird things we're
doing (with `CoRegisterClass`) in the Terminal _now_, and get them
selfhosted, before building on them too much.
This PR does have windows registering the `Monarch` class with COM. When
windows are created, they'll as the Monarch if they should create a new
window or not. In this PR, the Monarch will always reply "yes, please
make a new window".
Similar to other projects in our solution, we're adding 3 projects here:
* `Microsoft.Terminal.Remoting.lib`: the actual implementation, as a
static lib.
* `Microsoft.Terminal.Remoting.dll`: The implementation linked as a DLL,
for use in `WindowsTerminal.exe`.
* `Remoting.UnitTests.dll`: A unit test dll that links with the static
lib.
There are plenty of TODOs scattered about the code. Clearly, most of
this isn't implemented yet, but I do have more WIP branches. I'm using
[`projects/5`](https://github.com/microsoft/terminal/projects/5) as my
notation for TODOs that are too small for an issue, but are part of the
whole Process Model 2.0 work.

This commit makes "Open in Windows Terminal" Context menu work again for
directory background even on system that OS fix is not applied.
This is a fallback solution to OS fixes mentioned in #6414.
While OS fix is on its way, we need a fallback that works on existing OS
versions.
The approach to this is: when no item is selected (nullptr for
IShellItemArray*), we use shell api to query the path of current active
Explorer window. A special case is handled for Windows Desktop. Once
we are able to obtain the path, we launch Windows Terminal with it.
## Validation Steps Performed
1. Right click on desktop to bring up the Context menu, pick "Open in
Windows Terminal", verify that a terminal is opened with correct
initial path.
2. Open a few File Explorer windows, pick any window, navigate to a
folder, click on "Background" to bring up the context menu, click
"Open in Windows Terminal" verify that a terminal is opened with
correct initial path.
Closes#6414
Converts the poly text out string and width buffers to use a memory pool since we free/alloc those every frame and are just going to reuse them over and over.
## PR Checklist
* [x] Supports #3075
* [x] I work here.
* [x] Profiled memory before/after. Tested manually with `big.txt`.
## Detailed Description of the Pull Request / Additional comments
- Sets up a PMR memory pool for the GDI Engine. It tends to alloc and free a bunch of little buffers during painting frames. The pool will likely hold onto that memory frame over frame, but we'd just be using it again and again and again anyway. So this way we avoid all the system memory allocator locks and syscalls.
## Validation Steps Performed
- Ran `big.txt` about 10x in the window. Checked WPR/WPA profile output before/after.
This commit replaces DeviceComm with the interface IDeviceComm and the
concrete implementation type ConDrvDeviceComm. This work is done in
preparation for different device backends.
In addition to separating out ConDrv-specific behavior, I've introduced
a "handle exchange" interface.
HANDLE EXCHANGE
---------------
There are points where we give ConDrv opaque handle identifiers to our
input buffer, output buffer and process data. The exact content of the
opaque identifier is meaningless to ConDrv: the driver's only
interaction with these identifiers is to hold onto them and send back
whichever are pertinent for each API call.
Because of that, we used the raw register-width pointer value of the
input buffer, output buffer or process data _as_ the opaque handle
value.
This works very well for ConDrv <-> conhost using the ConDrvDeviceComm.
It works less well for something like the "logging" DeviceComm that will
log packets to a file: those packets *cannot* contain pointer values (!)
To address this, and to afford flexibility to DeviceComm implementers,
I've introduced a two-member complement of handle management functions:
* `ULONG_PTR PutHandle(void*)` registers an object with the DeviceComm
and returns an opaque identifier.
* `void* GetHandle(ULONG_PTR)` takes an opaque identifier and returns
the original object.
ConDrvDeviceComm implements PutHandle and GetHandle by casting the
object pointer to the "opaque handle value", which maintains wire format
compatibility[1] with revisions of conhost prior to this change.
Simpler DeviceComm implementations that require handle tracking but
cannot bear raw pointers can implement these functions by returning an
autoincrementing ID (or similar) and registering the raw object pointer
in a mapping.
I've audited all existing handle exchanges with the driver and updated
them to use Put/GetHandle.
(I intended to add DestroyHandle, but we are not equipped for handle
removal at the moment. ConsoleHandleData/ConsoleProcessHandle are
destroyed during wait routine completion, on client disconnect, etc.
This does mean that an id<->pointer mapping will grow without bound, but
at a cost of ~8 bytes per entry and a short-lived console session I am
not too concerned about the cost.)
[1] Wire format compatibility is not required, and later we may want to
switch ConDrvDeviceComm to `EncodePointer` and `DecodePointer` just to
insulate us against a spurious ConDrv packet allowing for an arbitrary
4/8-byte read and subsequent liftoff into space.

I loved the pixel shaders in #7058, but that PR needed a bit of polish
to be ready for ingestion. This PR is almost _exactly_ that PR, with
some small changes.
* It adds a new pre-profile setting `"experimental.pixelShaderPath"`,
which lets the user set a pixel shader to use with the Terminal.
- CHANGED FROM #7058: It does _not_ add any built-in shaders.
- CHANGED FROM #7058: it will _override_
`experimental.retroTerminalEffect`
* It adds a bunch of sample shaders in `samples/shaders`. Included:
- A NOP shader as a base to build from.
- An "invert" shader that inverts the colors, as a simple example
- An "grayscale" shader that converts all colors to grayscale, as a
simple example
- An "raster bars" shader that draws some colored bars on the screen
with a drop shadow, as a more involved example
- The original retro terminal effects, as a more involved example
- It also includes a broken shader, as an example of what heppens
when the shader fails to compile
- CHANGED FROM #7058: It does _not_ add the "retroII" shader we were
all worried about.
* When a shader fails to be found or fails to compile, we'll display an
error dialog to the user with a relevant error message.
- CHANGED FROM #7058: Originally, #7058 would display "error bars"
on the screen. I've removed that, and had the Terminal disable the
shader entirely then.
* Renames the `toggleRetroEffect` action to `toggleShaderEffect`.
(`toggleRetroEffect` is now an alias to `toggleShaderEffect`). This
action will turn the shader OR the retro effects on/off.
`toggleShaderEffect` works the way you'd expect it to, but the mental
math on _how_ is a little weird. The logic is basically:
```
useShader = shaderEffectsEnabled ?
(pixelShaderProvided ?
pixelShader :
(retroEffectEnabled ?
retroEffect : null
)
) :
null
```
and `toggleShaderEffect` toggles `shaderEffectsEnabled`.
* If you've got both a shader and retro enabled, `toggleShaderEffect`
will toggle between the shader on/off.
* If you've got a shader and retro disabled, `toggleShaderEffect` will
toggle between the shader on/off.

This commit introduces the terminal settings editor (to wit: the
Settings UI) as a standalone project. This project, and this commit, is
the result of two and a half months of work.
TSE started as a hackathon project in the Microsoft 2020 Hackathon, and
from there it's grown to be a bona-fide graphical settings editor.
There is a lot of xaml data binding in here, a number of views and a
number of view models, and a bunch of paradigms that we've been
reviewing and testing out and designing and refining.

This PR defines a series of `NOSOMETHING` macros in PCHs, in order to
prevent `windows.h` from bringing a lot of rarely used things into the
project.
Theoretically this should make PCH generation and overall complication
faster, but I didn't really benchmark the speed.
Another benefit would be reducing the symbol noises caused by
`windows.h`.
In my #8489 we want to use boost's small_vector type, but that PR is
kinda messy by adding boost and also making a meaningful change. So
here I'm splitting out the boost addition to its own PR so that one can
be more focused on the allocation improvement and consumption of boost.
This fixes the issue with the settings UI where clicking the browse
buttons would cause an exception to be thrown when we tried to display a
picker without an originating HWND.
It turns out that pickers need a hosting/parent window, and Xaml Islands
doesn't furnish us with a CoreWindow that's set up for that use case.
Alas!
Raymond Chen's [blog post on the matter] suggests that we should
hand the HWND off through some classic COM interface. To do that
properly, Terminal's various components need to implement that interface
and propagate the HWND down where it's needed.
Thanks to a [Xaml compiler issue], we can't actually do that. To work
around that, we've begged and borrowed different methods for pushing
HWNDs around:
1. Using IInitializeWithWindow in secret
2. A member that takes a uint64
3. An interface that offers a function that will "wire up" the HWND.
I chose (1) because AppHost can implement IInitializeWithWindow, but
TerminalPage cannot. We're just pretending that TerminalPage _can_.
I chose (2) because none of the Xaml types in TerminalSettingsEditor can
implement the interface thanks to the aforementioned compiler issue, but
we don't have an escape hatch like AppHost that lives in the same module
and can help us do the propagation.
I chose (3) because I didn't want to commit the same sin as (2) _seven
times_ for every different type of settings page that exists. (3) is
backed by "IHostedInWindow", and anybody who knows they have to use
IInitializeWithWindow to tie an HWND to an object can call
IHostedInWindow.TryPropagateHostingWindow() on that object.
House of cards.

Many include statements use forward slashes, while others use backwards
slashes. This is inconsistent formatting. For this reason, I changed the
backward slashes to forward slashes since that is the standard.
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.

## Summary of the Pull Request
This adds `ToJson` functions to `Profile`, `GlobalAppSettings`, and `ColorScheme`. They are used in `CascadiaSettings` to completely serialize an instance of the settings model. Thanks to #7923, all of the settings are `std::optional`, and `JsonUtils` only writes out values that are actually populated.
`CascadiaSettings::WriteSettingsToDisk` serializes the current settings and writes them to the settings.json. A backup file is created with your old contents.
#### Limitations:
- all of the color schemes are serialized regardless of them coming from defaults.json or settings.json
- keybindings/actions are copied/pasted

Until now, we relied on WM_SIZING to ensure that the island is not
downsized below minimal allowed dimensions. However, on some occasions
WM_WINDOWPOSCHANGED, e.g. when anchoring a window to the top/bottom of
the screen. This message will use dimensions obtained from
WM_GETMINMAXINFO. Until now we didn't override this value, falling back
to the defaults. As a result we got an inconsistent behavior (at least
when attaching the anchor).
I added logic very similar to the one we use in IslandWindow::_OnSizing
to the MINMAXINFO handler: snap the client area, add non client
exclusive are, consider DPI along the computation.
## Validation Steps Performed
* Manual testing of minimizing, maximizing, resizing, attaching
different anchors, etc.
Closes#8026
Display a warning message when the DirectX renderer resolves a font that
isn't the one you selected to warn that it couldn't be found.
Also I wrote the dialog event chain out of `TermControl` to be reusable
in the future for other messages the control might want to tell a host
about and various levels.
## Validation Steps Performed
- Manual validation, setting bad font name, fixing font name with
`settings.json`.
Closes#1017
The JsonUtils changes in #8018 revealed that we need more robust,
configurable optional handling. We learned that there's a class of
values that was previously underrepresented in our API: _strings that
have an explicit empty value_.
The Settings model supports starting directory, icon, background image
et al values that are empty. That emptiness _overrides_ a value set in a
lower layer, so it is not sufficient to represent the empty value for
any one of those fields as an unset optional.
There are a couple other settings for which we've implemented a
hand-rolled option type (for roughly the same reason): foreground,
background, any color fields that override values from the color scheme
_or_ the lower layer profile.
These requirements are best fulfilled by better optional support in
JsonUtils. Where the library would originally detect known types of
optional and pre-filter them out during `GetValue` and `SetValue`, it
will now defer to another conversion trait.
This commit introduces a helper conversion trait and an "option oracle".
The conversion trait will use the option oracle to detect emptiness,
generate empty option values, and read values out of option types. In so
doing, the trait is insulated from the implementation details of any
specific option type.
Any special logic for handling JSON null and option types has been
stripped from GetValue. Due to this, there is an express change in
behavior for some converters:
* `GetValue<T>(jsonNull)` where `T` is **not** an option type[1] has
been upgraded from a silent no-op to an exception.
Further, I took the opportunity to replace NullableSetting with
std::optional<std::optional<T>>, which accurately represents "setting
that the user might explicitly clear". I've added a test to
JsonUtilsTests to make sure it can serialize/deserialize double
optionals the way we expect it to.
Tests (Local, Unit for TerminalApp/SettingsModel):
Summary: Total=140, Passed=140, Failed=0, Blocked=0, Not Run=0, Skipped=0

In preparation for the Settings UI, we needed to make some changes to
Tab to abstract out shared, common functionality between different types
of tab. This is the result of that work. All code references to the
settings have been removed or reverted.
Contains changes from #8053, #7802.
The messages below only make sense in the context of the Settings UI,
which this pull request does not bring in. They do, however, provide
valuable information.
From #7802 (@leonMSFT):
> This PR's goal was to add an option to the `OpenSettings` keybinding to

besides just passing the compile flag.

## Detailed Description of the Pull Request / Additional comments
* We've been setting C++17 with just the flag passed to the compiler
`cl.exe`. But it turns out that this particular `LanguageStandard`
option will need to be set appropriately one day for us to use C++20
modules (as evidenced by the latest VS16.8 preview that I tried out to
explore modules.) The `AdditionalOption` alone isn't enough to ensure
that modules can be "seen" by other projects after production, but
`LanguageStandard` is (and will set the compiler option as appropriate
as well as whatever internal goo that MSBuild needs to hook up other
stuff.)

Overall design:
- Upon startup, TerminalCore gives the TextBuffer some patterns it
should know about
- Whenever something in the viewport changes (i.e. text
output/scrolling), TerminalControl tells TerminalCore (through a
throttled function for performance) to retrieve the visible pattern
locations from the TextBuffer
- When the renderer encounters a region that is associated with a
pattern, it paints that region differently

All our JSON files are _actually_ JSONC files - json with comments.
A well-behaved application that accepts JSON should accept and ignore
comments. However, `jsonlint` is not a well behaved application in this
regard.
So, to prevent the linter from complaining about our JSON comments, we
need to disable it entirely. THAT'S RIGHT, there's not a setting to
allow JSONC.
See #8076 as an example of this working.
This will also unblock #7462.
This commit introduces 8 more variants of the .ICO file, embeds the
right ones into WindowsTerminal.exe, and adds code that will select the
most appropriate icon at runtime.
Since we're a Centennial application, the "application" icon inside our

Alt-Tab window.

This commit also adds an override UCD and migrates all of the overrides
from GetQuickCharWidth into it.
GetQuickCharWidth
-----------------
The removal of overrides from GQCW reduces the number of comparisons
required for looking up a single character's width from 41 (32
individual ranged comparisons from GQCW + 8+1 from the binary search in
CPWD) to 11 (2 from GQCW, 8+1 from CPWD).
GQCW also incorrectly marked 67 reserved codepoints as `Wide` when they
should have been `Narrow`.
The codepoints whose definitions have changed from `Wide` to `Narrow` are:
```
2E9A 2EF4 2EF5 2EF6 2EF7 2EF8 2EF9 2EFA 2EFB 2EFC 2EFD 2EFE 2EFF 2FD6
2FD7 2FD8 2FD9 2FDA 2FDB 2FDC 2FDD 2FDE 2FDF 2FE0 2FE1 2FE2 2FE3 2FE4
2FE5 2FE6 2FE7 2FE8 2FE9 2FEA 2FEB 2FEC 2FED 2FEE 2FEF 2FFC 2FFD 2FFE
2FFF 31E4 31E5 31E6 31E7 31E8 31E9 31EA 31EB 31EC 31ED 31EE 31EF 321F
A48D A48E A48F FE1A FE1B FE1C FE1D FE1E FE1F FE53 FE67
```
All of them are reserved, but those reserved regions are marked as narrow
in the UCD.
This change also offers us the chance to document exactly why we're
overriding a specific character range. Comments from the override
document will be copied to the generated CPWD table.
New in Unicode 13.0
------------------
Some widths have changed due to previously-reserved characters becoming
_used_ such as U+32FF SQUARE ERA NAME REIWA, the Tangut components
756-768, the entire Khitan Small Script character set, and the Tangut
Ideographs.
A number of the changes in this diff are due to better/worse comment
tracking and the removal of the Emoji/EPres comments. The script once
mistakenly applied comments to packed regions (and it has been updated
to not do so.)
Validation
----------
I build a test application that compared codepoints 0-FFFF for GQCW
against their new registered widths.
## Summary of the Pull Request
Introduces `IInheritable` as an interface that helps move cascading settings into the Terminal Settings Model. `GlobalAppSettings` and `Profile` both are now `IInheritable`. `CascadiaSettings` was updated to `CreateChild()` for globals and each profile when we are loading the JSON data.
IInheritable does most of the heavy lifting. It introduces a two new macros and the interface. The macros help implement the fallback functionality for nullable and non-nullable settings.

#7876 - `Copy()` needs to be updated to include _parent
This introduces an addendum to the Terminal Settings Model spec that
covers inheritance and fallback. Basically, settings objects will now
have a reference to a parent object. If the settings object does not
have a setting defined, it will ask its parent to resolve the value. A
parent is set using the `Clone()` function. `Copy()` is used to copy the
value and structure of the settings model, whereas `Clone()` is used to
copy a reference to the settings model and build an inheritance tree.

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.

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
to serialize settings objects into JSON.
As a proof of concept, `ToJson` and `UpdateJson` were added to
`ColorScheme`.
Getters and setters for members and colors in the color table were added
and polished.

`ColorScheme` is a particularly easy example of serialization because it
has _no fallback_.
Added a few tests for JSON serializers.
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)
x86_64 clang | O0 | O1 | O2 + O3

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
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

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.

data is yet to be handled. This effectively fixes#120 by making Sixel
graphics sequences *ignored* instead of printed.

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.)

Yes, the numbers are wrong. No, it doesn't really matter.

#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.

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_.

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.

This PR adds support for the `SGR 53` and `SGR 55` escapes sequences,
which enable and disable the ANSI _overline_ graphic rendition

`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

## 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.

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.

---
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
manually. This change generalizes the F7 handler into a "direct key
event" handler that uses the same focus and tunneling method to send
different key events, and then uses it to send VK_MENU.

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.

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.

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.
Closes#3377Closes#3487
## Summary of the Pull Request
We have a number of bugs in the Terminal that all have the same singular root cause - VT input does not carry the same fidelity that Win32 input does. For Win32 applications there are certain keystrokes that simply cannot be represented with VT sequences.
This is my proposal for how we'll handle all these cases. I'm proposing a _new VT sequence_, which will enable the Terminal to send input with all of the information that an `INPUT_RECORD` might have, to conpty. There, conpty will be able to send input to the client application with the same fidelity they're used to, enabling these keys to work for those applications once again.

## Detailed Description of the Pull Request / Additional comments
_read the spec_
This commit introduces Generate-CodepointWidthsFromUCD, a powershell
(7+) script that will parse a UCD XML database in the UAX 42 format from
https://www.unicode.org/Public/UCD/latest/ucdxml/ and generate
CodepointWidthDetector's giant width array.
By default, it will emit one UnicodeRange for every range of non-narrow
glyphs with a different Width + Emoji + Emoji Presentation class;
however, it can be run in "packing" and "full" mode.
* Packing mode: ignore the width/emoji/pres class and combine adjacent
runs that CPWD will treat the same.
* This is for optimizing the number of individual ranges emitted
into code.
* Full mode: include narrow codepoints (helpful for visualization)
It also supports overrides, provided in an XML document of the same format
as the UCD itself. Entries in the overrides files are applied after the
entire UCD is read and will replace any impacted ranges.
The output (when packing) looks like this:
```c++
// Generated by Generate-CodepointWidthsFromUCD -Pack:True -Full:False
// on 05/17/2020 02:47:55 (UTC) from Unicode 13.0.0.

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.
A couple of codepoints, namely the card suites, male and female signs,
and white and black smiling faces were changed to have a two-column
width as part of #5795 since they were specified as emoji in Unicode's
emoji list v13.0[1].
These particular glyphs also show up in some of the most fundamental
code pages, such as CP437[2] and WGL4[3]. We should
not be touching the width of the glyphs in these codepages, as suddenly
changing a long-time-running narrow glyph to use two-columns all of a
sudden will surely break (and has already broken) things.

This is an attempt to simplify the SGR (Select Graphic Rendition)
implementation in conhost, to cut down on the number of methods required
in the `ConGetSet` interface, and pave the way for future improvements
and bug fixes. It already fixes one bug that prevented SGR 0 from being
correctly applied when combined with meta attributes.
* This a first step towards fixing the conpty narrowing bugs in issue
#2661
* I'm hoping the simplification of `ConGetSet` will also help with
#3849.
* Some of the `TextAttribute` refactoring in this PR overlaps with
similar work in PR #1978.
## Detailed Description of the Pull Request / Additional comments
The main point of this PR was to simplify the
`AdaptDispatch::SetGraphicsRendition` implementation. So instead of
having it call a half a dozen methods in the `ConGetSet` API, depending
on what kinds of attributes needed to be set, there is now just one call
to get current attributes, and another call to set the new value. All
adjustments to the attributes are made in the `AdaptDispatch` class, in
a simple switch statement.
To help with this refactoring, I also made some change to the
`TextAttribute` class to make it easier to work with. This included
adding a set of methods for setting (and getting) the individual
attribute flags, instead of having the calling code being exposed to the
internal attribute structures and messing with bit manipulation. I've
tried to get rid of any methods that were directly setting legacy, meta,
and extended attributes.
Other than the fix to the `SGR 0` bug, the `AdaptDispatch` refactoring
mostly follows the behaviour of the original code. In particular, it
still maps the `SGR 38/48` indexed colors to RGB instead of retaining
the index, which is what we ultimately need it to do. Fixing that will
first require the color tables to be unified (issue #1223), which I'm
hoping to address in a followup PR.
But for now, mapping the indexed colors to RGB values required adding an
an additional `ConGetSet` API to lookup the color table entries. In the
future that won't be necessary, but the API will still be useful for
other color reporting operations that we may want to support. I've made
this API, and the existing setter, standardise on index values being in
the "Xterm" order, since that'll be essential for unifying the code with
the terminal adapter one day.
I should also point out one minor change to the `SGR 38/48` behavior,
which is that out-of-range RGB colors are now ignored rather than being
clamped, since that matches the way Xterm works.
## Validation Steps Performed
This refactoring has obviously required corresponding changes to the
unit tests, but most were just minor updates to use the new
`TextAttribute` methods without any real change in behavior. However,
the adapter tests did require significant changes to accommodate the new
`ConGetSet` API. The basic structure of the tests remain the same, but
the simpler API has meant fewer values needed to be checked in each test
case. I think they are all still covering the areas there were intended
to, though, and they are all still passing.
Other than getting the unit tests to work, I've also done a bunch of
manual testing of my own. I've made sure the color tests in Vttest all
still work as well as they used to. And I've confirmed that the test
case from issue #5341 is now working correctly.
Closes#5341
The table that we refer to in `CodepointWidthDetector.cpp` to determine
whether or not a codepoint should be rendered as Wide vs Narrow was
based off EastAsianWidth[1]. If a codepoint wasn't included in this
table, they're considered Narrow. Many emojis aren't specified in the
EAW list, so this PR supplements our table with emoji codepoints from
emoji-data[2] in order to render most, if not all, emojis as full-width.
There are certain codepoints I've added to the comments (in case we want
to add them officially to the table in the future) that Microsoft
decided to give an emoji presentation even if it's specified as
Narrow/Ambiguous in the EAW list and are _not_ specified in the Unicode
emoji list. These include all of the Mahjong Tiles block, different
direction pencils (✎✐), different pointing index fingers (☜, ☞) among
others. I have no idea if I've captured all of them, as I don't know of
an easy way to detect which are Microsoft specific emojis.
## Validation Steps Performed
I have looked at so many emojis that I dream emoji.
These screenshots aren't encompassing _all_ emoji but I've tried to grab

## Summary of the Pull Request
This PR resolves an issue with the Git for Windows (MSYS) version of `less`. It _doesn't_ use VT processing for emitting text tothe buffer, so when it hits `WriteCharsLegacy`, `WC_DELAY_EOL_WRAP` is NOT set.
When this happens, `less` is writing some text that's longer than the width of the buffer to the last line of the buffer. We're hitting the
```c++
Status = AdjustCursorPosition(screenInfo, CursorPosition, WI_IsFlagSet(dwFlags, WC_KEEP_CURSOR_VISIBLE), psScrollY);
```
call in `_stream.cpp:560`.
The cursor is _currently_ at `{40, 29}`, the _start_ of the run of text that wrapped. We're trying to adjust it to `{0, 30}`, which would be the start of the next line of the buffer. However, the buffer is only 30 lines tall, so we've got to `IncrementCircularBuffer` first, so we can move the cursor there.
When that happens, we're going to paint frame. At the end of that frame, we're going to try and paint the cursor position. The cursor is still at `{40, 29}` here, so unfortunately, the `cursorIsInDeferredWrap` check in `XtermEngine::PaintCursor` is `false`. That means, conpty is going to try to move the cursor to where the console thinks the cursor actually is at the end of this frame, which is `{40, 29}`.
If we're painting the frame because we circled the buffer, then the cursor might still be in the position it was before the text was written to the buffer to cause the buffer to circle. In that case, then we DON'T want to paint the cursor here either, because it'll cause us to manually break this line. That's okay though, the frame will be painted again, after the circling is complete.

## Detailed Description of the Pull Request / Additional comments
### Background
- We want the Terminal to be fast at drawing. To be fast at drawing, we perform differential drawing, or only drawing what is different from the previous frame. We use DXGI's `Present1` method to help us with this as it helps us compose only the deltas onto the previous frame at drawing time and assists us in scrolling regions from the previous frame without intervention. However, it only works on strictly integer pixel row heights.
- Most of the hit testing and size-calculation logic in both the `conhost` and the Terminal products are based on the size of an individual cell. Historically, a cell was always dictated in a `COORD` structure, or two `SHORT` values... which are integers. As such, when we specify the space for any individual glyph to be displayed inside our terminal drawing region, we want it to fall perfectly inside of an integer box to ensure all these other algorithms work correctly and continue to do so.
- Finally, we want the Terminal to have font fallback and locate glyphs that aren't in the primary selected font from any other font it can find on the system that contains the glyph, per DirectWrite's font fallback mechanisms. These glyphs won't necessarily have the same font or glyph metrics as the base font, but we need them to fit inside the same cell dimensions as if they did because the hit testing and other algorithms aren't aware of which particular font is sourcing each glyph, just the dimensions of the bounding box per cell.
### How does Terminal deal with this?
- When we select a font, we perform some calculations using the design metrics of the font and glyphs to determine how we could fit them inside a cell with integer dimensions. Our process here is that we take the requested font size (which is generally a proxy for height), find the matching glyph width for that height then round it to an integer. We back convert from that now integer width to a height value which is almost certainly now a floating point number. But because we need an integer box value, we add line padding above and below the glyphs to ensure that the height is an integer as well as the width. Finally, we don't add the padding strictly equally. We attempt to align the English baseline of the glyph box directly onto an integer pixel multiple so most characters sit crisply on a line when displayed.
- Note that fonts and their glyphs have a prescribed baseline, line gap, and advance values. We use those as guidelines to get us started, but then to meet our requirements, we pad out from those. This results in fonts that should be properly authored showing gaps. It also results in fonts that are improperly authored looking even worse than they normally would.
### Now how does block and line drawing come in?
- Block and Line drawing glyphs are generally authored so they will look fine when the font and glyph metrics are followed exactly as prescribed by the font. (For some fonts, this still isn't true and we want them to look fine anyway.)
- When we add additional padding or rounding to make glyphs fit inside of a cell, we can be adding more space than was prescribed around these glyphs. This can cause a gap to be visible.
- Additionally, when we move things like baselines to land on a perfect integer pixel, we may be drawing a glyph lower in the bounding box than was prescribed originally.
### And how do we solve it?
- We identify all glyphs in the line and block drawing ranges.
- We find the bounding boxes of both the cell and the glyph.
- We compare the height of the glyph to the height of the cell to see if we need to scale. We prescribe a scale transform if the glyph wouldn't be tall enough to fit the box. (We leave it alone otherwise as some glyphs intentionally overscan the box and scaling them can cause banding effects.)
- We inspect the overhang/underhang above and below the boxes and translate transform them (slide them) so they cover the entire cell area.
- We repeat the previous two steps but in the horizontal direction.

This commit introduces a context menu for Tab and a new item,
"Color...", which will display a color picker.
A flyout menu, containing a custom flyout, is attached to each tab. The
flyout displays a palette of 16 preset colors and includes a color
picker. When the user selects or clears color, an event is fired, which
is intercepted by the tab to which the flyout belongs.
The changing of the color is achieved by putting the selected color in
the resource dictionary of the tab, using well-defined dictionary keys
(e.g. TabViewItemHeaderBackground). Afterwards the visual state of the
tab is toggled, so that the color change is visible immediately.
Custom-colored tabs will be desaturated (somewhat) by alpha blending
them with the tab bar background.
The flyout menu also contains a 'Close' flyout item.
## Validation Steps Performed
I've validated the behavior manually: start the program via the start
menu. Right click on the tab -> Choose a tab color.
The color flyout is going to be shown. Click a color swatch or click
'Select a custom color' to use the color picker. Use the 'Clear the
current color' to remove the custom color.
Closes#2994. References #3327.
Turns out we're still being a bit too aggressive when removing spaces.
If there are spaces at the end of the first run painted to a bottom
line, _and the bottom line was a different color than the previous_,
then we can't trim those spaces off the string. We still need to emit
those to make sure the terminal has colored spaces in it as well.

For our release builds, we're just going to integrate the UWPDesktop CRT
into our package and delete the package dependencies. It's very
difficult for users who do not have access to the store to get our
dependency packages, and we want to be robust and deployable everywhere.
Since these libraries can be redistributed, it's easiest if we simply
redistribute them.
Our package grows by ~550kb per architecture (compressed) because of
this. I've added validation that we don't have both the libs _and_ the
dependencies in the same package.

Also known as "Kill HRGN II: Kills Regions Dead (#5485)"
Copying the description from @greg904 in #4778.

My understanding is that the XAML framework uses another way of getting
mouse input that doesn't work with `WM_SYSCOMMAND` with `SC_MOVE`. It
looks like it "steals" our mouse messages like `WM_LBUTTONDOWN`.
Before, we were cutting (with `HRGN`s) the drag bar part of the XAML
islands window in order to catch mouse messages and be able to implement
the drag bar that can move the window. However this "cut" doesn't only
apply to input (mouse messages) but also to the graphics so we had to
paint behind with the same color as the drag bar using GDI to hide the
fact that we were cutting the window.
The main issue with this is that we have to replicate exactly the
rendering on the XAML drag bar using GDI and this is bad because:
1. it's hard to keep track of the right color: if a dialog is open, it
will cover the whole window including the drag bar with a transparent
white layer and it's hard to keep track of those things.
2. we can't do acrylic with GDI
So I found another method, which is to instead put a "drag window"
exactly where the drag bar is, but on top of the XAML islands window (in
Z order). I've found that this lets us receive the `WM_LBUTTONDOWN`
messages.

window in the UWP application frame host.

I've also added a build rule producing a lib for {fmt}.
This will be required for our next OS ingestion.
* Cleaning up the whitelist a bit.
* The magic to exclude repeated characters worked 👍
* Every successful run on master now logs its suggested cleanup, e.g. for 5740e197c2 has https://github.com/microsoft/terminal/runs/596271627#step:4:37
* ⚠️ This check-spelling 0.0.15a+ tolerates Windows line endings in the `whitelist.txt` file (another project I touched had some `.gitconfig` magic which required supporting them).
This means that if someone edits the file w/ something that likes Windows line endings, the file will successfully convert (instead of it being ignored and check-spelling complaining about everything). Most likely anyone else who then edits the file will use something that will maintain the line endings.
This commit adds a `WT_PROFILE_ID` environment variable, which contains
the guid of the active profile.
It also teaches ConptyConnection to take an environment map on creation.
We had to do a little manual jiggery with the WSLENV environment
variable as passed by the creator.

## Summary of the Pull Request
When WSL vim prints the initial empty buffer (the one that's just a bunch of '\~'s), it prints this by doing the following:
* Print '\~' followed by enough spaces to clear the line
* Use CUP (`^[[H`) to move the cursor to the start of the next line
* repeat until the buffer is full
When we'd get the line of "\~ "... in conhost, we'd mark that line as wrapped.
Logically, it doesn't really make any sense that when we follow that up by moving the cursor, the line is wrapped. However, this is just how conhost is right now.
This wasn't ever a problem in just conhost before, because we really didn't care if lines in the alt buffer were "wrapped" or not. Plus, when vim would get resized, it would just reprint it's own buffer anyways. Nor was this a problem in conpty before this year (2020). We've only just recently added logic to conpty to try and preserve wrapped lines.
Initially, I tried fixing this by breaking the line manually when the cursor was moved. This seemed to work great, except for the win32 vim.exe. Vim.exe doesn't emit a newline or a CUP to get to the next line. It just _goes for it_ and keeps printing. So there's _no way_ for us to know the line broke, because they're essentially just printing one long line, assuming we'll automatically move the cursor.
So instead, I'm making sure to emit the proper number of spaces at the end of a line when the line is wrapped. We won't do any funny business in that scenario and try to optimize for them, we'll _just print the spaces_.

This pull request makes sure we still get a usable (for troubleshooting purposes) version number in the about dialog and settings file when the user is running unpackaged.
This introduces a magic LCID constant (0x0409).B y default, Package ES emits
version resource information that says we're localized to ... language zero.
It also emits a language-coded version block for 0x0409 (en-US).
These two things cannot both be true. Collapse the wave function by hardcoding
0x0409.
Now that the Terminal is doing a better job of actually marking which
lines were and were not wrapped, we're not always copying lines as
"wrapped" when they should be. We're more correctly marking lines as not
wrapped, when previously we'd leave them marked wrapped.
The real problem is here in the `ScrollFrame` method - we'd manually
newline the cursor to make the terminal's viewport shift down to a new
line. If we had to scroll the viewport for a _wrapped_ line, this would
cause the Terminal to mark that line as broken, because conpty would
emit an extra `\n` that didn't actually exist.
This more correctly implements `ScrollFrame`. Now, well move where we
"thought" the cursor was, so when we get to the next `PaintBufferLine`,
if the cursor needs to newline for the next line, it'll newline, but if
we're in the middle of a wrapped line, we'll just keep printing the
wrapped line.
A couple follow up bugs were found to be caused by the same bad logic.
See #5039 and #5161 for more details on the investigations there.

This pull request introduces unexpanded variables (`%DEFAULT_PROFILE%`,
`%VERSION%` and `%PRODUCT%`) to the user settings template and code to
expand them.
While doing this, I ran into a couple things that needed to widen from
accepting strings to accepting string views. I also had to move
application name and version detection up to AppLogic and expose the
AppLogic singleton.
The dynamic profile generation logic had to be moved to before we inject
the templated variables, as the new default profile depends on the
generated dynamic profiles.
References #5189, #5217 (because it has a dependency on `VERSION` and
`PRODUCT`).

## Validation Steps Performed
Deleted my settings and watched them regenerate.
_Technically_, "wether" is a word but I'd be shocked if there's a scenario for
us to use it properly in this repo, so I'm pulling it from the dictionary.
Also, in #5200, we added "VTE", which is totally a valid acronym, to the codebase,
but not the whitelist. I'm not sure why the bot let me merge it anyways, but I'm
fixing it now.
## Summary of the Pull Request
As we've learned in #979, not all touchpads are created equal. Some of them have bad drivers that makes scrolling inactive windows not work. For whatever reason, these devices think the Terminal is all one giant inactive window, so we don't get the mouse wheel events through the XAML stack. We do however get the event as a `WM_MOUSEWHEEL` on those devices (a message we don't get on devices with normally functioning trackpads).
This PR attempts to take that `WM_MOUSEWHEEL` and manually dispatch it to the `TermControl`, so we can at least scroll the terminal content.
Unfortunately, this solution is not very general purpose. This only works to scroll controls that manually implement our own `IMouseWheelListener` interface. As we add more controls, we'll need to continue manually implementing this interface, until the underlying XAML Islands bug is fixed. **I don't love this**. I'd rather have a better solution, but it seems that we can't synthesize a more general-purpose `PointerWheeled` event that could get routed through the XAML tree as normal.

## Detailed Description of the Pull Request / Additional comments
I've also added a `til::point` conversion _to_ `winrt::Windows::Foundation::Point`, and some scaling operators for `point`
## Validation Steps Performed
* It works on my HP Spectre 2017 with a synaptics trackpad
- I also made sure to test that `tmux` works in panes on this laptop
* It works on my slaptop, and DOESN'T follow this hack codepath on this machine.
This pull request introduces the `til::math` namespace, which provides some casting functions to be used in support of `til::point` and `til::size`. When point/size want to ingest a floating-point structure, they _must_ be instructed on how to convert those floating-point values into integers.
This enables:
```
Windows::Foundation::Point wfPoint = /* ... */;
til::point tp{ til::math::rounding, wfPoint };
```
Future thoughts: should the TilMath types be stackable? Right now, you cannot get "checked + rounding" behavior (where it throws if it doesn't fit) so everything is saturating.

Correct scrolling invalidation region for tmux in pty w/ bitmap
Add tracing for circling and scrolling operations. Fix improper
invalidation within AdjustCursorPosition routine in the subsection about
scrolling down at the bottom with a set of margins enabled.
## References
- Introduced with #5024
## Detailed Description of the Pull Request / Additional comments
- This occurs when there is a scroll region restriction applied and a
newline operation is performed to attempt to spin the contents of just
the scroll region. This is a frequent behavior of tmux.
- Right now, the Terminal doesn't support any sort of "scroll content"
operation, so what happens here generally speaking is that the PTY in
the ConHost will repaint everything when this happens.
- The PTY when doing `AdjustCursorPosition` with a scroll region
restriction would do the following things:
1. Slide literally everything in the direction it needed to go to take
advantage of rotating the circular buffer. (This would force a
repaint in PTY as the PTY always forces repaint when the buffer
circles.)
2. Copy the lines that weren't supposed to move back to where they were
supposed to go.
3. Backfill the "revealed" region that encompasses what was supposed to
be the newline.
- The invalidations for the three operations above were:
1. Invalidate the number of rows of the delta at the top of the buffer
(this part was wrong)
2. Invalidate the lines that got copied back into position (probably
unnecessary, but OK)
3. Invalidate the revealed/filled-with-spaces line (this is good).
- When we were using a simple single rectangle for invalidation, the
union of the top row of the buffer from 1 and the bottom row of the
buffer from 2 (and 3 was irrelevant as it was already unioned it)
resulted in repainting the entire buffer and all was good.
- When we switched to a bitmap, it dutifully only repainted the top line
and the bottom two lines as the middle ones weren't a consequence of
intersect.
- The logic was wrong. We shouldn't be invalidating rows-from-the-top
for the amount of the delta. The 1 part should be invalidating
everything BUT the lines that were invalidated in parts 2 and 3.
(Arguably part 2 shouldn't be happening at all, but I'm not optimizing
for that right now.)
- So this solves it by restoring an entire screen repaint for this sort
of slide data operation by giving the correct number of invalidated
lines to the bitmap.
## Validation Steps Performed
- Manual validation with the steps described in #5104
- Automatic test `ConptyRoundtripTests::ScrollWithMargins`.
Closes#5104
This repository tends to use `/`s in branch names.
Unfortunately, `branch: "*"` at present only matches a single
level, which means it would match a branch named `foo` but not `bar/foo`.
Given that I don't think this repository is actively using tags,
and given that the general cost for the spell checker isn't particularly
high, it's better to remove the filtering so that all branches get
checked.
Worst case, a branch that is also tagged and has spelling errors
will get two comments complaining about those spelling errors.
This is just some minor whitelisting/additions to dictionaries to catch
up between when the spell checker PR was written and when it was finally
merged.
This is basically taking the spelling output from
499f24a29e and putting it into files.
The choice of files is arbitrary. I'm adding a `math.txt` dictionary
because it's a reasonable example.
The goal here is to get master to a green check mark
