Fixes a regression of command palette accessibility. The regression was
introduced in #8377 by setting `IsTabStop` to false. Though the commands
would light up, the focus didn't technically get on the command, so the
screen reader would just read the text box.
## Validation Steps Performed
Opened the command palette while NVDA is active. It now reads the
commands as focus moves on them.
The terminal WPF container might have a (0,0) render size when VS
eagerly attempts to initialize the terminal tool window when it is
pinned during startup, but no actual UI is shown due to the VS welcome
dialog that shows up before VS can build the terminal tool window.
We've fixed this issue previously in other areas but only recently did
we get a complete enough dump to find the corner cases for this issue.
This should patch all the gaps that cause this bug.
## Validation Steps Performed
I've manually validated the scenarios shown in the user dumps.
## Summary of the Pull Request
After rename ends (either by enter or escape) the rename box
gets collapsed and the focus moves to the next tab stop
in the TabView (e.g., new tab button).
To overcome this:
* Added RenameEnded event to TabHeaderControl
* Forwarded it as RenamerDeactivated from TerminalTab
* Registered in the TerminalPage to focus the active control upon
RenamerDeactivated if focus didn't move to tab menu.
This means, no matter how you close the renamer,
the current terminal gains the focus.

## Summary of the Pull Request
Prior to this PR, if the Windows key was pressed as a part of a key combination, then selection was being dismissed. For example, when a user pressed `Windows` + `Shift` + `S` keys to invoke the _Capture & Annotate_ tool.
This PR adds an exception for not clearing selection when either of the two Windows keys are pressed as part of a key combination.
It was tested manually by trying to reproduce the issue.

## Detailed Description of the Pull Request / Additional comments
### Window Title Generation
Every time the renderer checks the title, it's doing two bad things that
I've fixed:
1. It's assembling the prefix to the full title doing a concatenation.
No one ever gets just the prefix ever after it is set besides the
concat. So instead of storing prefix and the title, I store the
assembled prefix + title and the bare title.
2. A copy must be made because it was returning `std::wstring` instead
of `std::wstring&`. Now it returns the ref.
### Dirty Area Return
Every time the renderer checks the dirty area, which is sometimes
multiple times per pass (regular text printing, again for selection,
etc.), a vector is created off the heap to return the rectangles. The
consumers only ever iterate this data. Now we return a span over a
rectangle or rectangles that the engine must store itself.
1. For some renderers, it's always a constant 1 element. They update
that 1 element when dirty is queried and return it in the span with a
span size of 1.
2. For other renderers with more complex behavior, they're already
holding a cached vector of rectangles. Now it's effectively giving
out the ref to those in the span for iteration.
### Bitmap Runs
The `til::bitmap` used a `std::optional<std::vector<til::rectangle>>`
inside itself to cache its runs and would clear the optional when the
runs became invalidated. Unfortunately doing `.reset()` to clear the
optional will destroy the underlying vector and have it release its
memory. We know it's about to get reallocated again, so we're just going
to make it a `std::pmr::vector` and give it a memory pool.
The alternative solution here was to use a `bool` and
`std::vector<til::rectangle>` and just flag when the vector was invalid,
but that was honestly more code changes and I love excuses to try out
PMR now.
Also, instead of returning the ref to the vector... I'm just returning a
span now. Everyone just iterates it anyway, may as well not share the
implementation detail.
### UTF-8 conversions
When testing with Terminal and looking at the `conhost.exe`'s PTY
renderer, it spends a TON of allocation time on converting all the
UTF-16 stuff inside to UTF-8 before it sends it out the PTY. This was
because `ConvertToA` was allocating a string inside itself and returning
it just to have it freed after printing and looping back around again...
as a PTY does.
The change here is to use `til::u16u8` that accepts a buffer out
parameter so the caller can just hold onto it.
## Validation Steps Performed
- [x] `big.txt` in conhost.exe (GDI renderer)
- [x] `big.txt` in Terminal (DX, PTY renderer)
- [x] Ensure WDDM and BGFX build under Razzle with this change.

A bug in VS 16.8 makes the WAP packaging project copy System.Core.dll
from the CLR into all WAP packages. We don't need it, and it adds 300kb
to our package (670kb uncompressed).
VS 16.9 sets the AddAdditionalExplicitAssemblyReferences to suppress
this assembly. If we do the same, we can avoid the reference *and* be
eady for VS 16.9.
Contains:
- Delegation Configurator that can lookup/edit/save configuration information to registry
- Conhost can lookup the CLSID of a registered default
- Conhost has the ability to handoff a starting visible-window interactive session to the registered default
- Velocity key since this is a big deal and we want to be careful
- IDL for the interface

Avoid sending mouse move / wheel / release to Terminal in the first place.
This kind of short-circuiting will prevent us reaching the

These functions have a dependency on the "VT Redirected" versions of
VkKeyScanW, MapVirtualKeyW and GetKeyState. Those implementations depend
on the service locator and therefore the entire interactivity stack.
This meant that anybody depending on just Types had to pull in **the
entire host** worth of dependencies (!).
Since these functions are only used in places where we have or are
testing interactivity, it makes sense to consolidate them here.

`CascadiaSettings::UpdateColorSchemeReferences` had two bugs in it:
1. we would never check/update the base layer
2. we would explicitly set the color scheme on a profile referencing the
old name
This PR fixes both of those issues by checking/updating the base layer,
and ensuring that we check if a profile has an explicit reference before
updating it.
Since the affected code is in TSM, I also created an automated local
test.
## Validation Steps Performed
Bug repro steps.

Test added.
Closes#9094
[DHowett's scenario]: https://github.com/microsoft/terminal/issues/9094#issuecomment-776412781
* Currently TerminalPage registers on CmdPal key events:
* To invoke bindings when the palette is open
* Since some key combinations are not triggered by KeyDown
it registers for PreviewKeyDown
* As a result bindings might be preferred over navigation
(e.g., ctrl+v will paste into Terminal rather than into search box)
* To fix this, I moved all interactions inside the CmdPal into
PreviewKeyDown as well
* In addition, added specific handling for copy/paste
which now allow to interact with search box even if not focused
Closes#9044
Teaches renderer base to keep thread alive if engine requests it.
`DxEngine` now requests it if shaders are on.
- The render engine interface now has a true/false to return whether the
specific renderer wants another frame to immediately follow up. The
renderer base will ask for this information as it ends the paint on
any particular engine (which is the time where invalid regions are
typically cleaned up) and just poke the render thread the same as if
an invalidation request came in from outside of render-land. That will
trigger the render thread to just keep moving in the same way as any
other invalidation.

## Summary of the Pull Request
**If you're reading this PR and haven't signed off on #8135, go there first.**
This provides the basic parts of the implementation of #4472. Namely:
* We add support for the `--window,-w <window-id>` argument to `wt.exe`, to allow a commandline to be given to another window.
* If `window-id` is `0`, run the given commands in _the current window_.
* If `window-id` is a negative number, run the commands in a _new_ Terminal window.
* If `window-id` is the ID of an existing window, then run the commandline in that window.
* If `window-id` is _not_ the ID of an existing window, create a new window. That window will be assigned the ID provided in the commandline. The provided subcommands will be run in that new window.
* If `window-id` is omitted, then create a new window.

## Detailed Description of the Pull Request / Additional comments
Note that `wt -w 1 -d c:\foo cmd.exe` does work, by causing window 1 to change
There are limitations, and there are plenty of things to work on in the future:
* [ ] We don't support names for windows yet
* [ ] We don't support window glomming by default, or a setting to configure what happens when `-w` is omitted. I thought it best to lay the groundwork first, then come back to that.
* [ ] `-w 0` currently just uses the "last activated" window, not "the current". There's more follow-up work to try and smartly find the actual window we're being called from.
* [ ] Basically anything else that's listed in projects/5.
I'm cutting this PR where it currently is, because this is already a huge PR. I believe the remaining tasks will all be easier to land, once this is in.
## Validation Steps Performed
I've been creating windows, and closing them, and running cmdlines for a while now. I'm gonna keep doing that while the PR is open, till no bugs remain.
# TODOs
* [x] There are a bunch of `GetID`, `GetPID` calls that aren't try/caught 😬
- [x] `Monarch.cpp`
- [x] `Peasant.cpp`
- [x] `WindowManager.cpp`
- [x] `AppHost.cpp`
* [x] If the monarch gets hung, then _you can't launch any Terminals_ 😨 We should handle this gracefully.
- Proposed idea: give the Monarch some time to respond to a proposal for a commandline. If there's no response in that timeframe, this window is now a _hermit_, outside of society entirely. It can't be elected Monarch. It can't receive command lines. It has no ID.
- Could we gracefully recover from such a state? maybe, probably not though.
- Same deal if a peasant hangs, it could end up hanging the monarch, right? Like if you do `wt -w 2`, and `2` is hung, then does the monarch get hung waiting on the hung peasant?
- After talking with @miniksa, **we're gonna punt this from the initial implementation**. If people legit hit this in the wild, we'll fix it then.
1. Fix progress value not updated
2. Introduce TabStatus object and bind both TabHeaderControl and CommandPalette to it
3. Add support for read-only mode indicator

## Summary of the Pull Request
The TerminalSettings object we create from profiles no longer gets passed into the control, instead, a child of that object gets passed into the control. Any overrides the control makes to the settings then live in the child. So, when we do a settings reload, we simply update the child's parent and the overrides will remain.

Introduces the `SettingContainer`. `SettingContainer` is used to wrap a setting in the settings UI and provide the following functionality:
- a reset button next to the header
- tooltips and automation properties for the setting being wrapped
- a comment stating if you are currently overriding a setting

## Detailed Description of the Pull Request / Additional comments
A few highlights in this PR:
- CommonResources.xaml:
- we need to merge the SettingContainerStyle.xaml in there. Otherwise, XAML doesn't merge these files properly and can't apply the template.
- Profiles.cpp:
- view model checks if the starting directory and background image were reset, to determine which value to show when unchecking the special value
- `Profiles::OnNavigatedTo()` needs a property changed handler to update its own "Current<Setting>" and update the UI properly
- Profiles.xaml:
- basically wrapped all of the settings we want to be inheritable in there
- `Binding` is used instead of `x:Bind` in some places because `x:Bind` can't find the parent `SettingContainer` and gives you a compiler error.
- Resources.resw:
- had to set the "HeaderText" and "HelpText" on each setting container. Does a decent localization burden, unfortunately.
- `SettingContainer` files
- This operates by creating a template and applying that template over other settings. This allows you to inject the existing controls inside of this. This means that we need to provide our UIElements names and access/modify them via `OnApplyTemplate`
- We had to remove the header from each individual control, and have `SettingContainer` be in charge of it. This allows us to add the reset button in there.
- Due to the problem mentioned earlier about CommonResources.xaml, we can't reference anything from CommonResources.xaml.
- Using `DependencyProperty` to let us set a few properties in the XML files. Particularly, `Has<Setting>` and `Clear<Setting>` are what do all the heavy lifting of interacting with the inheritance model.
## Demo
## Validation Steps Performed
- Verified correct binding behavior with the following generic setting controls:
- radio buttons
- toggle switch
- text block
- slider
- settings with browse buttons
- the background image alignment control
- controls with special check boxes (starting directory and background image)
## Next Steps
- The automation properties have been verified using NVDA. This is a part of resolving #8899.
- The override text is currently "Overrides a setting". According to #8269, we actually want to add a hyperlink in there that navigates to the parent profile object. This will be a follow-up task as it requires settings model changes.

## Validation Steps Performed
## Summary of the Pull Request
Fixes#5205, by replacing another use of `MapVirtualKeyW` with `ToUnicodeEx`.
The latter just seems to be much more consistent at translating key combinations in general.
In this particular case though it fixes the issue, because there's no differentiation in `MapVirtualKeyW` for whether it failed to return a character (`'\0'`) or succeeded in turning `^@` into `'\0'`.
`ToUnicodeEx` on the other hand returns the success state separately from the translated character.

## Detailed Description of the Pull Request / Additional comments
This PR changes the behavior of the `Ctrl+Alt+Key` handling slightly:
⚠️ `ToUnicodeEx` returns unshifted characters. ⚠️
For instance `Ctrl+Alt+a` is now turned into `^[^a`. Due to how ASCII works this is essentially the same though because `'A' & 0b11111` and `'a' & 0b11111` are the same.
## Validation Steps Performed
* Run `showkey -a`
* Ensured `Ctrl+Alt+Space` as well as `Ctrl+Alt+Shift+2` are turned into `^[^@`
* Ensured other, random `Ctrl+Alt+Key` combination behave identical to the current master
This adds "paste filtering" & "bracketed paste mode" to the Windows
Terminal.
I've moved the paste handling code in `TerminalControl` to
`Microsoft::Console::Util` to be able to easily test it, and the paste
transformer from `TerminalControl` to `TerminalCore`.
Supersedes #7508
References #395 (overall bracketed paste support request)
Tests added. Manually tested.
The command palette is ephemeral and is dismissed if the focus
moves to an element which is not the palette's descendant.
Unfortunately, this breaks the (right-click) context menu,
as it is not a child of the palette
(popups are hosted on a separate root element).

## Detailed Description of the Pull Request / Additional comments
Read the spec
- Fixes empty app title when `showTerminalTitleInTitlebar` is false
- Fixes Tab title propagation to Window title when
`showTerminalTitleInTitlebar` is false
- Fixes Tab title propagation to Window - title doesn't update when
Window is unfocused
1. There were a missing
`_settings.GlobalSettings().ShowTitleInTitlebar()` check. Because of
this Title update event was being fired even when
`showTerminalTitleInTitlebar` is false. This results in empty tab
title to propagate to Window title. Also then after switching tabs
back and forth, tab title propagates to window title. These shouldn't
propagate when `showTerminalTitleInTitlebar` is false. I added the
`showTerminalTitleInTitlebar` check in relevant logic to fix the
behavior.
2. Code was checking `tab.FocusState() != FocusState::Unfocused` , but
when the whole terminal window is not in focus, the active tab is
also in Unfocused state. This was preventing tab title to propagate
to window title when application is unfocused. I added the logic of
checking matching selected tabs' index. This fixes the issue.
## Validation Steps Performed
I did the reproduce steps descripted in the issue to reproduce the bugs.
After applying the fixes, the bugs don't appear anymore while doing the

## Summary of the Pull Request
This is a more detailed spec for two parts of the "Process Model 2.0" work that's being tracked in #5000. In particular, this spec focuses on the management of Windows Terminal windows, including opening new tabs in existing windows.
Largely, the reader is expected to have already read the spec in progress in #7240, and already be familiar with the concept of "Monarch" and "Peasant" windows as introduced by that spec. For that reason, ⚠ **THIS PR IS TARGETING THE BRANCH FOR #7240** ⚠.
### Abstract
> This document is intended to serve as an addition to the [Process Model 2.0
> Spec]. That document provides a big-picture overview of changes to the entirety
> of the Windows Terminal process architecture, including both the split of
> window/content processes, as well as the introduction of monarch/peasant
> processes. The focus of that document was to identify solutions to a set of
> scenarios that were closely intertwined, and establish these solutions would
> work together, without preventing any one scenario from working. What that
> document did not do was prescribe specific solutions to the given scenarios.
>
> This document offers a deeper dive on a subset of the issues in [#5000], to
> describe specifics for managing multiple windows with the Windows Terminal. This
> includes features such as:
>
> * Run `wt` in the current window ([#4472])
> * Single Instance Mode ([#2227])

_\*<sup>\*</sup><sub>\*</sub> read the spec <sub>\*</sub><sup>\*</sup>\*_
### Why are these two separate documents?
I felt that the spec that is currently in review in #7240 and this doc should remain separate, yet closely related documents. #7240 is more about showing how this large set of problems discussed in #5000 can all be solved technically, and how those solutions can be used together. It establishes that none of the proposed solutions for components of #5000 will preclude the possibility of other components being solved. What it does _not_ do however is drill too deeply on the user experience that will be built on top of those architectural changes.
This doc on the other hand focuses more closely on a pair of scenarios, and establishes how those scenarios will work technically, and how they'll be exposed to the user.
### TODO:
* [x] A thought - How will we handle arguments like `--fullscreen`, `--initialSize r,c`? They only apply when creating a new window, right?
* [x] When a `wt -s 1 split-pane` command is executed, we'll need to make sure to not _also_ create a new tab

## Summary of the Pull Request
This spec is _exceptionally long_, and is currently a work in progress. There are a few more things I'd like to have experimentally verified (though, I'm fairly certain they _will_ work, with the right combination of flags and such). Additionally, a few sections have remaining TODOs before the spec is finished. However, this spec is already fairly long, and I want to give people as much time to get their eyes on it as possible.

## Detailed Description of the Pull Request / Additional comments
_\*<sup>\*</sup><sub>\*</sub> read the spec <sub>\*</sub><sup>\*</sup>\*_
"disabledProfileSources" is saved to `CascadiaSettings` _not_
`GlobalAppSettings` (and, even then, it's only read when it's used,
never saved). This PR specifically detects if it was defined in
settings.json, and copies it over when the settings are serialized.
## Validation Steps Performed
1. Added "disabledProfileSources" to settings.json, then serialized. -->
"disabledProfileSources" is now maintained.
2. Updated `CascadiaSettings` serialization test
Closes#9032
## Summary of the Pull Request
Fix for #9021
Turns out that what was happening is that the _parent_ pane's `Closed` event was being caught by the tab, and parent panes always have `nullopt` as their id. So now the `Pane::Id()` call always returns an optional, allowing us to check if it has a value before we access it.

## Detailed Description of the Pull Request / Additional comments
The two shaders I wrote are not especially pretty or interesting, but they should hopefully serve as simple examples for anyone looking to do animated effects. One simply draws a line of inverted pixels that scrolls down the screen, and the other fades the background back and forth between two colors.
I've added a new section to the readme explaining how the shaders work to achieve animated effects.
I've also updated the comments on the existing shaders to clear up a couple of things:
1. Be more explicit that `Time` represents seconds since the shader loaded. Though obvious in hindsight, this was not clear to me when I was first learning/experimenting
2. Explain that `tex` ranges from 0,0 to 1,1. This is important because, when trying to port GLSL shaders from shadertoy, I at first assumed `fragCoord` and `tex` are the same thing but the former actually ranges from 0,0 to the resolution of the canvas, so some of the math doesn't work out if you just substitute it with `tex`.
Any and all feedback welcome.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
I ran the shaders manually in a dev build of the Terminal. I auto-spellchecked and manually proofread my additions to the readme and verifed the markdown rendering on github.
This PR fixes the parsing of OSC 9;9 sequences with path surrounded by
quotation marks.
Original OSC 9;9 PR: #8330
Unit test added. Manually tested with oh-my-posh.
Closes#8930
* Fix the incorrect terminalCore path in tests.xml
* Change the -TaefArgs argument of Invoke-OpenConsoleTests and
Invoke-TaefInNewWindow to be []string, allowing
multiple arguments to be passed to TAEF
