## Summary of the Pull Request
This is an enormously trivial nit - when we launch maximized, we don't draw the maximize button in the "restore" state.
This PR changes the terminal to manually update the Maximize button on launch, once the titlebar is added to the UI tree.

## Summary of the Pull Request
When we maximize the window, shrink the caption buttons (the min, max, close buttons) down to 32px tall, to be the same height as the `TabRowControl`. This way, the tabs will be flush with the top of the display.

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

This pull request moves swaths of Cascadia to use `til::color` for color
interop. There are still some places where we use `COLORREF`, such as in
the ABI boundaries between WinRT components.
I've also added two more til::color helpers - `with_alpha`, which takes
an existing color and sets its alpha component, and a
`Windows::UI::Color` convertor pair.
Future direction might include a `TerminalSettings::Color` type at the
idl boundary so we can finally stop using UInt32s (!) for color.
## Validation Steps Performed
Tested certain fragile areas:
* [x] setting the background with OSC 11
* [x] setting the background when acrylic is in use (which requires
low-alpha)
The AKB serializer is used in the tracelogging pipeline.
Chatted with @zadjii-msft about ganking the deserializers. The form
they'll take in the future is probably very different from this.
We'll need to have some better tracking of the _source_ or _pass_ a
setting was read during so that we can accurately construct an internal
settings attribution model. Diffing was very extremely cool, but we
didn't end up needing it.
This apparently drops our binary size by a whopping _zero bytes_ because
the optimizer was smarter than us and actually totally deleted it.
## Summary of the Pull Request
When we're dragging the tab around, if you execute a `ClosePane`/`CloseTab`, then we should make sure to actually activate a new tab, so that focus doesn't just fall into the void.

We suppress `_OnTabItemsChanged` events during a rearrange, so if a tab is closed while we're rearranging tabs, the we don't fire the `SelectionChanged` event that we usually do during a close that would select the new tab.

- Confirmed that tragging a tab out, closing it, then dragging it back in does nothing.
This PR reverts a relatively minor change that was made incorrectly to
ConPTY in #5771.
In that PR, I authored two tests. One of them actually caught the bug
that was supposed to be fixed by #5771. The other test was simply
authored during the investigation. I believed at the time that the test
revealed a bug in conpty that was fixed by _removing_ this block of
code. However, an investigation itno #5839 revealed that this code was
actually fairly critical.
So, I'm also _skipping_ this buggy test for now. I'm also adding a
specific test case to this bug.
The problem in the bugged case of `WrapNewLineAtBottom` is that
`WriteCharsLegacy` is wrapping the bottom row of the ConPTY buffer,
which is causing the cursor to automatically move to the next line in
the buffer. This is because `WriteCharsLegacy` isn't being called with
the `WC_DELAY_EOL_WRAP` flag. So, in that test case,
* The client emits a wrapped line to conpty
* conpty fills the bottom line with that text, then dutifully increments
the buffer to make space for the cursor on a _new_ bottom line.
* Conpty reprints the last `~` of the wrapped line
* Then it gets to the next line, which is being painted _before_ the
client emits the rest of the line of text to fill that row.
* Conpty thinks this row is empty, (it is) and manually breaks the row.
However, the test expects this row to be emitted as wrapped. The problem
comes from the torn state in the middle of these frames - the original
line probably _should_ remain wrapped, but this is a sufficiently rare
case that the fix is being punted into the next release.
It's possible that improving how we handle line wrapping might also fix
this case - currently we're only marking a row as wrapped when we print
the last cell of a row, but we should probably mark it as wrapped
instead when we print the first char of the _following_ row. That work
is being tracked in #5800
### The real bug in this PR
The problem in the `DeleteWrappedWord` test is that the first line is
still being marked as wrapped. So when we get to painting the line below
it, we'll see that there are no characters to be printed (only spaces),
we emit a `^[20X^[20C`, but the cursor is still at the end of the first
line. Because it's there, we don't actually clear the text we want to
clear.
So DeleteWrappedWord, #5839 needs the `_wrappedRow = std::nullopt;`
statement here.

Terminal should try not to join the choir invisible when the clipboard
API straight up horks it.
This accounts for ~3% of the crashes seen in 1.0RC1 and ~1% of the
crashes seen all-up in the last 14 days.

Fixes#4906.
It turns out that we weren't really adequately guarding calls to
SetSelectionEnd and friends.
We're clearing the active selection when the window resizes, but we're
doing so by nulling out the std::optional<Selection> it lives in. Later,
though, when we set the selection endpoint we're using "_selection->".
Optional's operator-> has undefined behavior when the optional doesn't
have a value in it.
In our case, it looks like it was returning whatever the value was prior
to it being emptied out. PivotSelection would attempt to access an
out-of-bounds coordinate when the buffer got smaller during a resize.
The solution is to guard both levels of selection endpoint manipulation
in a check for an active selection.
Apparently, this accounts for somewhere between 7% and 14% of our
crashes on 1.0RC1.
Repro was:
Use Win+Arrow to snap the window while in the middle of a selection.

## Detailed Description of the Pull Request / Additional comments
When we switched from full-screen repaints to incremental rendering, it seems like we exposed a situation where some display drivers and hardware combinations do not handle scroll and/or dirty regions (from `IDXGISwapChain::Present1`) without blurring the data from the previous frame. As we're really close to ship, I'm offering two options to let people in this situation escape it on their own. We hope in the future to figure out what's actually going on here and mitigate it further in software, but until then, these escape hatches are available.
1. `experimental.rendering.forceFullRepaint` - This one restores the pre-778 behavior to the Terminal. On every single frame paint, we'll invalidate the entire screen and repaint it.
2. `experimental.rendering.software` - This one uses the software WARP renderer instead of using the hardware and display driver directly. The theory is that this will sidestep any driver bugs or hardware variations.
One, the other, or both of these may be field-applied by users who are experiencing this behavior.
Reverting #778 completely would also resolve this, but it would give back our largest performance win in the whole Terminal project. We don't believe that's acceptable when seemingly a majority of the users are experiencing the performance benefit with no detriment to graphical display.
## Validation Steps Performed
- [x] Flipped them on and verified with the debugger that they are being applied to the rendering pipeline
- [ ] Gave a private copy to community members in #5759 and had them try whether one, the other, or both resolved their issue.
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.

## 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.

If we're fullscreen, the TabView isn't `Visible`. If it's not `Visible`,
it's _not_ going to raise a `SelectionChanged` event, which is what we
usually use to focus another tab. Instead, we'll have to do it manually
here.
So, what we're going to try to do is move the focus to the tab to the
left, within the bounds of how many tabs we have.
EX: we have 4 tabs: [A, B, C, D]. If we close:
* A (`tabIndex=0`): We'll want to focus tab B (now in index 0)
* B (`tabIndex=1`): We'll want to focus tab A (now in index 0)
* C (`tabIndex=2`): We'll want to focus tab B (now in index 1)
* D (`tabIndex=3`): We'll want to focus tab C (now in index 2)
`_UpdatedSelectedTab` will do the work of setting up the new tab as the
focused one, and unfocusing all the others.
Also, we need to _manually_ set the SelectedItem of the tabView here. If
we don't, then the TabView will technically not have a selected item at
all, which can make things like ClosePane not work correctly.

then checked the msix for the correct name/icon.
This is actually related to another issue we have, #3917. I think if the system is set to "Dark" theme, but the app is set to light theme, then the brush lookup in `_ClearNewTabButtonColor` still returns to us the dark theme brushes.
Fortunately, since we're not actually setting the color of the new tab button anymore, we can just remove the call to that method now, and loop back on it later.

The Erase All VT sequence (`^[[2J`) is supposed to erase the entire
contents of the viewport. The way it usually does this is by shifting
the entirety of the viewport contents into scrollback, and starting the
new viewport below it.
Currently, conpty doesn't propagate that state change correctly. When
conpty gets a 2J, it simply erases the content of the connected
terminal's viewport, by writing over it with spaces. Conpty didn't
really have a good way of communicating "your viewport should move", it
only knew "the buffer is now full of spaces".
This would lead to bugs like #2832, where pressing <kbd>ctrl+L</kbd> in
`bash` would delete the current contents of the viewport, instead of
moving the viewport down.
This PR makes sure that when conpty sees a 2J, it passes that through
directly to the connected terminal application as well. Fortunately, 2J
was already implemented in the Windows Terminal, so this actually fixes
the behavior of <kbd>ctrl+L</kbd>/`clear` in WSL in the Terminal.
## References
* #4252 - right now this isn't the _most_ optimal scenario, we're
literally just printing a 2J, then we'll perform "erase line" `height`
times. The erase line operations are all redundant at this point - the
entire viewport is blank, but conpty doesn't really know that.
Fortunately, #4252 was already filed for me to come through and
optimize this path.

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.

## Summary of the Pull Request
This PR implements a pair of shims for `cmd` and `powershell`, so that their `cls` and `Clear-Host` functions will clear the entire terminal buffer (like they do in conhost), instead of just the viewport. With the conpty viewport and buffer being the same size, there's effectively no way to know if an application is calling these API's in this way with the intention of clearing the buffer or the viewport. We absolutely have to guess.
Each of these shims checks to see if the way that the API is being called exactly matches the way `cmd` or `powershell` would call these APIs. If it does, we manually write a `^[[3J` to the connected terminal, to get he Terminal to clear it's own scrollback.
~~_⚠️ If another application were trying to clear the **viewport** with an exactly similar API call, this would also cause the terminal scrollback to get cleared ⚠️_~~
* [x] Should these shims be restricted to when the process that's calling them is actually `cmd.exe` or `powershell.exe`? Can I even do this? I think we've done such a good job of isolating the client process information from the rest of the host code that I can't figure out how to do this.
- YES, this can be done, and I did it.
* [ ] **TODO**: _While I'm here_, should I have `DoSrvPrivateEraseAll` (the implementation for `^[[2J`, in `getset.cpp`) also manually trigger a EraseAll in the terminal in conpty mode?

We've got a weird crash that happens terribly inconsistently, but pretty
readily on migrie's laptop, only in Debug mode. Apparently, there's some
weird ref-counting magic that goes on during teardown, and our
Application doesn't get closed quite right, which can cause us to crash
into the debugger. This of course, only happens on exit, and happens
somewhere in the `...XamlHost.dll` code.
Crazily, if we _manually leak the `Application`_ here, then the crash
doesn't happen. This doesn't matter, because we really want the
Application to live for _the entire lifetime of the process_, so the only
time when this object would actually need to get cleaned up is _during
exit_. So we can safely leak this `Application` object, and have it just
get cleaned up normally when our process exits.

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

## Summary of the Pull Request
Based on the discussion in #5479, it seems that the crash is caused by a race condition due to not obtaining the write lock before calling `TriggerFontChange`.
I'm not totally sure if my approach is the right one, but I've taken the lock out of `_RefreshSize` since it seems like all calls of `_RefreshSize` come after a `TriggerFontChange`/`UpdateFont`. Then I just
made sure all calls of `TriggerFontChange`/`UpdateFont` are preceded with a `LockForWriting`.

If a class has a constructor which can be called with a single argument,
then this constructor becomes conversion constructor because such a
constructor allows conversion of the single argument to the class being
constructed. To ensure these constructors are passed the argument of its
type, I labeled them explicit.
In some header files, there were constructors that took a value that
could involve implicit conversions, so I added explicit to ensure that
does not happen.

## Detailed Description of the Pull Request / Additional comments
Basically, during a resize, we try to restore the viewport position
correctly, and part of that checks where the current commandline ends.
However, when we do that, the commandline's _current_ state still
reflects the _old_ buffer size, so resizing to be smaller can cause us
to throw an exception, when we find that the commandline doesn't fit in
the new viewport cleanly.
By hiding it, then redrawing it, we avoid this problem entirely. We
don't need to perform the check on the old commandline contents (since
they'll be empty), and we'll redraw it just fine for the new buffer size

The origin of this bug is that as newlines are emitted, we'll accumulate an enormous scroll delta into a selection region, to the point of overflowing a `SHORT`. When the overflow occurs, the `Terminal` would fail to send a `NotifyScroll()` to the `TermControl` hosting it.
For this bug to repro, we need to:
- Have a sufficiently large buffer, because each newline we'll accumulate a delta of (0, ~bufferHeight), so (bufferHeight^2 + bufferHeight) > SHRT_MAX
- Have a selection

This PR fixes a couple of issues with TSFInputControl alignment:
1. The emoji picker IME in particular would show up overlapping the
current buffer row because I stupidly didn't realize that
`TextBlock.ActualHeight` is 0 right after initialization and before
it has any text. So, the emoji picker will show up on the bottom of
the 0 height TextBlock, which overlaps the current buffer row. This
isn't a problem with CJK because inputting text _causes_ the IME to
show up, so by the time the IME shows up, the TextBlock has text and
accordingly has a height.
2. It turns out the emoji picker IME doesn't follow the `TextBlock`
bottom, unlike Chinese and Japanese IME, so if a user were to compose
near the edge of the screen and let the `TextBlock` start line
wrapping, the emoji IME doesn't follow the bottom of the `TextBlock`
as it grows. This means that the `TextBlock` position doesn't update
in the middle of composition, and the `LayoutRequested` event that it
fires at the beginning of composition is the only chance we get to
tell the emoji IME where to place itself. It turns out when we reset
`TextBlock.Text`, the ActualHeight doesn't get immediately reset back
to the min size. So if a user were to bring up the emoji IME before
`ActualHeight` is reset, the IME will show up way below the current
buffer row.
3. We don't currently `TryRedrawCanvas` when the window position changes
(resizing, dragging the window around), so sometimes dragging or
resizing the Terminal doesn't update the position of the IME. Ideally
it should be listening to some "window position changed" event, but
alas we don't have that and it would be much harder than this
incoming fix. We'll just track the window bounds as part of
`TryRedrawCanvas` and redraw if it changes. For the most part, this
will allow the IME to update to where the new window position is, but
it'll only be called if we receive a `LayoutRequested` event.

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.

Dustin's notes: I've based this on the implementation of the input sink
window in the UWP application frame host.
Tested manually in all configurations (debug, release) with snap,
drag, move, double-click and double-click on the resize handle. Tested

The renderer base and specific renderer engine do a lot of work to
remember the previous selection and compensate for scrolling regions and
deltas between frames. However, all that work doesn't quite match up
when the endpoints are changed out from under it. Unfortunately,
`TermControl` doesn't have a robust history of locking correctly in step
with the renderer nor does the renderer's `IRenderData` currently
provide any way of 'snapping' state at the beginning of a frame so it
could work without a full lock. So the solution for now is for the
methods that scroll the display in `TermControl` to take the lock that
is shared with the renderer's frame painter so they can't change out of
sync.

It was brought to our attention that shipping a font with ligatures as our default
font could be an accessibility issue for the visually-impaired. Unfortunately, we
don't have a renderer setting to disable ligatures (#759). Fortunately however, we
DO already have a version of Cascadia that doesn't have ligatures.
If we ship that and set it as our default font, we'll at least let people _opt_ to
have ligatures enabled by switching from `Cascadia Mono` to `Cascadia Code`.

In order to support a transparent background for the acrylic effect, the
renderer sets the alpha value to zero for the default background color.
However, when the _reversed video_ attribute is set, the background is
actually filled with the foreground color, and will not be displayed
correctly if it is made transparent. This PR addresses that issue by
making sure the rendered background color is opaque if the reversed
video attribute is set.
## References
* This is not a major issue at the moment, since the _reverse video_
attribute is not typically forwarded though conpty, but that will
change once #2661 is fixed.

## Detailed Description of the Pull Request / Additional comments
This simply adds an additional check in `Terminal::GetBackgroundColor`
to make sure the returned color is opaque if the _reverse video_
attribute is set. At some point in the future this check may need to be
extended to support the `DECSCNM` reverse screen mode, but for now
that's not an issue.
## Validation Steps Performed
I've run the test case from issue #5498, and confirmed that it now works
as expected. I've also got an experimental fix for #2661 that I've
tested with this patch, and that now displays _reverse video_ attributes
correctly too.

If Terminal is spawned by a shortcut that requests that it run in a new process group
while attached to a console session, that request is nonsense. That request will, however,
cause WT to start with Ctrl-C disabled. This wouldn't matter, because it's a Windows-subsystem
application. Unfortunately, that state is heritable. In short, if you start WT using cmd in
a weird way, ^C stops working inside the terminal. Mad.

## Detailed Description of the Pull Request / Additional comments
**WAS:**
- We were using implicit DPI scaling on the `ID2D1RenderTarget` and running all of our processing in DIPs (Device-Independent Pixels). That's all well and good for getting things bootstrapped quickly, but it leaves the actual scaling of the draw commands up to the discretion of the rendering target.
- When we don't get to explicitly choose exactly how many pixels tall/wide and our X/Y placement perfectly, the nature of floating point multiplication and division required to do the presentation can cause us to drift off slightly out of our control depending on what the final display resolution actually is.
- Differential drawing cannot work unless we can know the exact integer pixels that need to be copied/moved/preserved/replaced between frames to give to the `IDXGISwapChain1::Present1` method. If things spill into fractional pixels or the sizes of rows/columns vary as they are rounded up and down implicitly, then we cannot do the differential rendering.
**NOW:**
- When deciding on a font, the `DxEngine` will take the scale factor into account and adjust the proposed height of the requested font. Then the remainder of the existing code that adjusts the baseline and integer-ifies each character cell will run naturally from there. That code already works correctly to align the height at normal DPI and scale out the font heights and advances to take an exact integer of pixels.
- `TermControl` has to use the scale now, in some places, and stop scaling in other places. This has to do with how the target's nature used to be implicit and is now explicit. For instance, determining where the cursor click hits must be scaled now. And determining the pixel size of the display canvas must no longer be scaled.
- `DxEngine` will no longer attempt to scale the invalid regions per my attempts in #5185 because the cell size is scaled. So it should work the same as at 96 DPI.
- The block is removed from the `DxEngine` that was causing a full invalidate on every frame at High DPI.
- A TODO was removed from `TermControl` that was invalidating everything when the DPI changed because the underlying renderer will already do that.

## Summary of the Pull Request
This pull request ports the VT mouse code from TermControl to WpfTerminalControl. Our WPF control is a lot closer to Win32 than to Xaml, so our mouse event handler looks _nothing_ like the one that we got from Xaml. We can pass events through almost directly, because the window message handling in the mouse input code actually came from _conhost_. It's awesome.
Neither TermControl nor conhost pass hover events through when the control isn't focused, so I wired up focus events to make sure we acted the same.
Just like Terminal and conhost, mouse events are suppressed when <kbd>Shift</kbd> is held.
## Validation Steps Performed
Tested with MC, and tested by manually engaging SGR events in an Echo terminal.
## Summary of the Pull Request
This pull request ports #5096 to WpfTerminalControl, bringing it in line with the selection mechanics in Terminal. It also introduces double- and triple-click selection and makes sure we clear the selection when we resize.

This commit fixes a number of problems and code quality/health issues
with the AzureConnection.
This is a general tidying-up of the azure connection. It improves error
logging (like: it actually emits error logs...) and retry logic and the
state machine and it audits the exit points of the state machine for
exceptions and removes the HRESULT returns (so they either succeed and
transition to a new state or throw an exception or are going down
anyway).
There's also a change in here that changes how we display tenants. It
adds the "default domain" to the name, so that instead of seeing this:
Conhost (aaaaaaaa-aaaa-aaaa-aaaa-aaaaaaaaaaaa)
Default Directory (bbbbbbbb-bbbb-bbbb-bbbb-bbbbbbbbbbbb)
you see this
Conhost (conhost.onmicrosoft.com)
Default Directory (dustinhowett.onmicrosoft.com)
Changes:
* rework tenant/tenant storage and fix display names
Switch to the 2020 tenant API.
Instead of passing around four loose variables, create a Tenant class
and use that for packing/unpacking into/out of json (and the windows
credential store, where we "cleverly" used json for the tenant info
there too).
When displaying a tenant, use its display name if there is one, the
unknown resource string if there isn't, and the default domain if
there is one and the ID if there isn't.
Fixes#5325.
* use {fmt} for formatting request bodies
* remove dead strings
* rework/rename Request/HeaderHelper to
Send(Authenticated)ReqReturningJson
* rewrite polling to use std::chrono
* remove HR returns from state machine
* rename state handlers from _XHelper to _RunXState
* cleanup namespaces, prefix user input with >, remove namespaces
* Rework error handling
- _RequestHelper no longer eats exceptions.
- Delete the "no internet" error message.
- Wrap exceptions coming out of Azure API in a well-known type.
- Catch by type.
- Extract error codes for known failures (keep polling, invalid
grant).
- When we get an Invalid Grant, dispose of the cached refresh token
and force the user to log in again.
- Catch all printable exceptions and print them.
- Remove the NoConnect state completely -- just bail out when an
exception hits the toplevel of the output thread.
- Move 3x logic into _RefreshTokens and pop exceptions out of it.
- Begin abstracting into AzureClient
Fixes#5325 (by addressing its chief complaint).
Fixes#4803 (by triggering auth flow again if the token expires).
Improves diagnosability for #4575.
# Summary of the Pull Request
This PR will allow the cursor to be double width when on top of a double width character. This required changing `IsCursorDoubleWidth` to check whether the glyph the cursor's on top of is double width. This code is exactly the same as the original PR that addressed this issue in #2932. That one got reverted at some point due to the crashes related to it, but due to a combination of Terminal having come further since that PR and other changes to address use-after-frees, some of the crashes may/may not be relevant now. The ones that seemed to be relevant/repro-able, I attempt to address in this PR.
The `IsCursorDoubleWidth` check would fail during the `TextBuffer::Reflow` call inside of `Terminal::UserResize` occasionally, particularly when `newCursor.EndDeferDrawing()` is called. This is because when we tell the newCursor to `EndDefer`, the renderer will attempt to redraw the cursor. As part of this redraw, it'll ask if `IsCursorDoubleWidth`, and if the renderer managed to ask this before `UserResize` swapped out the old buffer with the new one from `Reflow`, the renderer will be asking the old buffer if its out-of-bounds cursor is double width. This was pretty easily repro'd using `cmatrix -u0` and resizing the window like a madman.
As a solution, I've moved the Start/End DeferDrawing calls out of `Reflow` and into `UserResize`. This way, I can "clamp" the portion of the code where the newBuffer is getting created and reflowed and swapped into the Terminal buffer, and only allow the renderer to draw once the swap is done. This also means that ConHost's `ResizeWithReflow` needed to change slightly.
In addition, I've added a WriteLock to `SetCursorOn`. It was mentioned as a fix for a crash in #2965 (although I can't repro), and I also figured it would be good to try to emulate where ConHost locks with regards to Cursor operations, and this seemed to be one that we were missing.
## PR Checklist
* [x] Closes#2713
* [x] CLA signed
* [x] Tests added/passed
## Validation Steps Performed
Manual validation that the cursor is indeed chonky, added a test case to check that we are correctly saying that the cursor is double width (not too sure if I put it in the right place). Also open to other test case ideas and thoughts on what else I should be careful for since I am quite nervous about what other crashes might occur.
## 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 fixes an issue where a shift+click selection with `copyOnSelect`
enabled would result in copying the content as a single line.
## Detailed Description of the Pull Request / Additional comments
I've been thinking a lot about this issue and how it relates to the
copy/paste discussions we've been having over the past few weeks.
Considering that the majority of users want regular copy, it makes sense
to default to that in this case too.
If a user wants to perform a special form of copy, it makes sense that
they should use their custom keybinding to accomplish that. This kind of
behavior aligns with that kind of philosophy.
## Validation Steps Performed
The following scenarios were tested with `copyOnSelect` enabled.
| scenario | behavior |

## Summary of the Pull Request
Renderer: Add support for backoff and auto-disable on failed retry
This commit introduces a backoff (150ms * number of tries) to the
renderer's retry logic (introduced in #2830). It also changes the
FAIL_FAST to a less globally-harmful render thread disable, so that we
stop blowing up any application hosting a terminal when the graphics
driver goes away.
In addition, it adds a callback that a Renderer consumer can use to
determine when the renderer _has_ failed, and a public method to kick it
back into life.
Fixes#5340.
This PR also wires up TermControl so that it shows some UI when the renderer tastes clay.

## Validation Steps Performed
I tested this by dropping the number of retries to 1 and forcing a TDR while doing `wsl cmatrix -u0`. It picked up exactly where it left off.
As a bonus, you can actually still type into the terminal when it's graphically suspended (and `exit` still works.). The block is _entirely graphical_.
We received a request from our localization team to switch from
printf-style format strings (%s, %u) to format strings with positional
argument support. I've been hoping for a long time to take a dependency
on C++20's std::format, but we're just not somewhere we can do that.
Enter fmt. fmt is _exactly_ the library we need.
Minor comparison:
std::wstring_view world = /* ... */;
auto str{ wil::str_printf<std::wstring>(L"hello %.*s",
gsl::narrow_cast<size_t>(world.size()),
world.data()) };
---
auto str{ fmt::format(L"hello {0}", world) };
If you really want to use the print specifiers:
auto str{ fmt::printf(L"hello %s", world) };
It's got optional compile-time checking for format strings and is
MIT-licensed. Eventually, we should be able to replace fmt:: with std::
and end up pretty much where we left off.

## Summary of the Pull Request
Adjusts DirectX renderer to use `til::bitmap` to track invalidation
regions. Uses special modification to invalidate a row-at-a-time to
ensure ligatures and NxM glyphs continue to work.
## References

* [x] Automated tests for `til` changes.
* [x] Am core contributor. And discussed with @DHowett-MSFT.
## Detailed Description of the Pull Request / Additional comments
- Applies `til::bitmap` as the new invalidation scheme inside the
DirectX renderer and updates all entrypoints for collecting
invalidation data to coalesce into this structure.
- Semi-permanently routes all invalidations through a helper method
`_InvalidateRectangle` that will expand any invalidation to cover the
entire line. This ensures that ligatures and NxM glyphs will continue
to render appropriately while still allowing us to dramatically reduce
the number of lines drawn overall. In the future, we may come up with
a tighter solution than line-by-line invalidation and can modify this
helper method appropriately at that later date to further scope the
invalid region.
- Ensures that the `experimental.retroTerminalEffects` feature continues
to invalidate the entire display on start of frame as the shader is
applied at the end of the frame composition and will stack on itself
in an amusing fashion when we only redraw part of the display.
- Moves many member variables inside the DirectX renderer into the new
`til::size`, `til::point`, and `til::rectangle` methods to facilitate
easier management and mathematical operations. Consequently adds
`try/catch` blocks around many of the already-existing `noexcept`
methods to deal with mathematical or casting failures now detected by
using the support classes.
- Corrects `TerminalCore` redraw triggers to appropriately communicate
scrolling circumstances to the renderer so it can optimize the draw
regions appropriately.
- Fixes an issue in the base `Renderer` that was causing overlapping
scroll regions due to behavior of `Viewport::TrimToViewport` modifying
the local. This fix is "good enough" for now and should go away when
`Viewport` is fully migrated to `til::rectangle`.
- Adds multiplication and division operators to `til::rectangle` and
supporting tests. These operates will help scale back and forth
between a cell-based rectangle and a pixel-based rectangle. They take
special care to ensure that a pixel rectangle being divided downward
back to cells will expand (with the ceiling division methods) to cover
a full cell when even one pixel inside the cell is touched (as is how
a redraw would have to occur).
- Blocks off trace logging of invalid regions if no one is listening to
optimize performance.
- Restores full usage of `IDXGISwapChain1::Present1` to accurately and
fully communicate dirty and scroll regions to the underlying DirectX
framework. This additional information allows the framework to
optimize drawing between frames by eliminating data transfer of
regions that aren't modified and shuffling frames in place. See
[Remarks](https://docs.microsoft.com/en-us/windows/win32/api/dxgi1_2/nf-dxgi1_2-idxgiswapchain1-present1#remarks)
for more details.
- Updates `til::bitmap` set methods to use more optimized versions of
the setters on the `dynamic_bitset<>` that can bulk fill bits as the
existing algorithm was noticeably slow after applying the
"expand-to-row" helper to the DirectX renderer invalidation.
- All `til` import hierarchy is now handled in the parent `til.h` file
and not in the child files to prevent circular imports from happening.
We don't expect the import of any individual library file, only the
base one. So this should be OK for now.
## Validation Steps Performed
- Ran `cmatrix`, `cmatrix -u0`, and `cacafire` after changes were made.
- Made a bunch of ligatures with `Cascadia Code` in the Terminal
before/after the changes and confirmed they still ligate.
- Ran `dir` in Powershell and fixed the scrolling issues
- Clicked all over the place and dragged to make sure selection works.
- Checked retro terminal effect manually with Powershell.

## Summary of the Pull Request
When a pane is closed by a connection, we want to wait until the connection is actually `Closed` before we fire the actual `Closed` event. If the connection didn't close gracefully, there are scenarios where we want to print a message to the screen.
However, when a pane is closed by the UI, we don't really care to wait for the connection to be completely closed. We can just do it whenever. So I've moved that call to be on a background thread.
## PR Checklist
* [x] Closes#1996
* [x] I work here
* [ ] Tests added/passed
* [n/a] Requires documentation to be updated
## Detailed Description of the Pull Request / Additional comments
Previously we'd wait for the connection to close synchronously when closing tabs or panes. For misbehaving applications like `ssh.exe`, that could result in the `Close` needing to `WaitForSingleObject` _on the UI thread_. If the user closed the tab / pane either with a keybinding or with some other UI element, they don't really care to see the error message anymore. They just want the pane closed. So there's no need to wait for the actual connection to close - the app can just continue on with whatever it was doing.
## Validation Steps Performed
Messed around with closing tabs, panes, tabs with many panes, the entire window. Did this with keybindings, or by clicking on the 'x' on the tab, the 'x' on the window, or using middle-click.
I'm always scared of things like this, so there's a 50% chance this makes things horribly worse.
## Summary of the Pull Request
This updates defaults.json to include the default values for all global and profile settings. Most default keybinding args are added too. This also updates a few outdated items found in the docs.

## Validation Steps Performed
After making the changes, I made sure all of the settings are deserialized by debugging and stepping through the `LayerJson` code.
- [X] Global Settings
I was mainly looking for two things:
- the key/value pair is found and read
- the value did not change before/after the pair was read
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.

When the connection printed text immediately, synchronously, as part of
Start() it would cause terminal to deadlock. We should start the
connection outside of lock.
The ConptyConnection would do this when it failed to launch something
(trivial repro: `wt -- xyz`).
The TelnetConnection would do this all the time, because local loopback
telnet is fast and easy.
This commit introduces another template replacement for the user's
default settings, COMMAND_PROMPT_LOCALIZED_NAME, which will be replaced
with the contents of the CommandPromptDisplayName resource.
By default, that will be "Command Prompt." This name change will apply
only for new users, and only on first launch. Changes in the system
locale after first launch will not impact the name of the profile.
If the user _removes_ the name from their command prompt profile, its
name will revert irrecoverably to "Command Prompt". They will not be
given a chance to regenerate a localized name.
Fixes#4476.
## Summary of the Pull Request
Renames the `requestedTheme` global setting to `theme`. Propagates updates to...

But we really know that `dark` is the one we care about here 😉
My basic idea was that `WM_CHAR` is just the better `WM_KEYDOWN`.
The latter fails to properly support common dead key sequences like in
#3516.
As such I added some logic to `Terminal::SendKeyEvent` to make it return
false if the pressed key represents a printable character.
This causes us to receive a character event with a (hopefully) correctly
composed code unit, which then gets sent to `Terminal::SendCharEvent`.
`Terminal::SendCharEvent` in turn had to be modified to support
potentially pressed modifier keys, since `Terminal::SendKeyEvent` isn't
doing that for us anymore.
Lastly `TerminalInput` had to be modified heavily to support character
events with modifier key states. In order to do so I merged its
`HandleKey` and `HandleChar` methods into a single one, that now handles
both cases.
Since key events will now contain character data and character events
key codes the decision logic in `TerminalInput::HandleKey` had to be
rewritten.

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.

`PRODUCT`).

## Validation Steps Performed
Deleted my settings and watched them regenerate.
The terminal lock is really only for the terminal; since the renderer is
fully owned by the control, not the Terminal, and we'll only be
receiving swap chain events after we register them during
initialization, we don't need to lock before _or_ after firing off the
coroutine.
Fixes#5203.
Because we cannot set RequestedTheme at the application level, we
occasionally run into issues where parts of our UI end up themed
incorrectly. Dialogs, for example, live under a different Xaml root
element than the rest of our application. This makes our popup menus and
buttons "disappear" when the user wants Terminal to be in a different
theme than the rest of the system. This hack---and it _is_ a
hack--walks up a dialog's ancestry and forces the theme on each element
up to the root. We're relying a bit on Xaml's implementation details
here, but it does have the desired effect.
It's not enough to set the theme on the dialog alone.

### Stop resurrecting dead roaming profiles
## 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.

## Summary of the Pull Request
This PR will allow TSFInputControl to redraw its Canvas and TextBlock in response to when the Terminal cursor position updates. This will fix the issue where during Korean composition, the first symbol of the next composition will appear on top of the previous composed character. Since the Terminal Cursor updates a lot, I've added some checks to see if the TSFInputControl really needs to redraw. This will also decrease the number of actual redraws since we receive a bunch of `LayoutRequested` events when there's no difference between them.

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
## Summary of the Pull Request
This pull request replaces about a hundred lines of manual xaml DOM code with a few lines of actual xaml, and wires up bound properties and event handlers in the good and correct way.
As part of this change, I've replaced the giant TextBlock in the about dialog with StackPanels, and replaced the Hyperlinks with HyperlinkButtons. This is in line with other platform applications.
URLs are _not_ localizable resources, so I moved them into the about dialog's xaml. Per #5138, we'll likely change them so that they get localization for "free" (dispatching based on the browser's language, without having to localize the URL in the application).
This commit rewrites a large swath of TermControl's initialization code.
* `TermControl` now _always_ has a `_terminal`; it will never be null
* Event registration for `_terminal` and any other available-at-init
fixtures has been moved into the constructor.
* Event handlers how more uniformly check `_closing` if they interact
with the _terminal.
* Swap chain attachment has been cleaned up and no longer uses a
coroutine when it's spawned from the UI thread.
* We have to register the renderer's swapchain change notification
handler after we set the swap chain, otherwise it'll call us back
when it initializes itself.
* `InitializeTerminal` now happens under the `_terminal`'s write lock
* Certain things that InitializeTerminal were calling themselves
attempted to take the lock. They no longer do so.
* TermControlAutomationPeer cannot take the read lock, because setting
the scrollbar's `Maximum` during `InitializeTerminal` will trigger
vivification of the automation peer tree; if it attempts to take the
lock it will deadlock during initialization.
* `BlinkCursor` was renamed to `CursorTimerTick` because it's the "Tick"
handler for the "CursorTimer".
* `DragDropHandler` was converted into a coroutine instead of just
_calling_ a coroutine.
Caveats:
Terminal may not have a `_buffer` until InitializeTerminal happens.
There's a nasty coupling between RenderTarget and TextBuffer that means
that we need to have a renderer before we have a buffer.
There's a second nasty coupling between RenderThread and Renderer: we
can't create a RenderThread during construction because it needs to be
given a renderer, and we can't create a Renderer during construction
because it needs a RenderThread. We don't want to kick off a thread
during construction.
Testing:
I wailed on this by opening and closing and resizing terminals and panes
and tabs, up to a hundred open tabs and one tab with 51 panes. I set one
tab to update the title as fast as it possibly could and tested
teardown, zoom, resize, mouse movement, etc. while this was all
happening.
Closes#4613.
This commit adds a debugging feature that can be activated by holding
down Left Alt _and_ Right Alt when a new tab is being created, if you
have the global setting "debugFeatures" set to true. That global setting
will default to true in DEBUG builds.
That debugging feature takes the form of a split pane that shows the raw
VT sequences being written to and received from the connection.
When those buttons are held down, every connection that's created as
part of a new tab is wrapped and split into _two_ connections: one to
capture input (and stand in for the main connection) and one to capture
output (and be displayed off to the side)
Closes#3206
This PR has evolved to encapsulate two related fixes that I can't really
untie anymore.
#2455 - Duplicating a tab that doesn't exist anymore
This was the bug I was originally fixing in #4429.
When the user tries to `duplicateTab` with a profile that doesn't exist
anymore (like might happen after a settings reload), don't crash.
As I was going about adding tests for this, got blocked by the fact that
the Terminal couldn't open _any_ panes while the `TerminalPage` was size
0x0. This had two theoretical solutions:
* Fake the `TerminalPage` into thinking it had a real size in the test -
probably possible, though I'm unsure how it would work in practice.
* Change `Pane`s to not require an `ActualWidth`, `ActualHeight` on
initialization.
Fortuately, the second option was something else that was already on my
backlog of bugs.
#4618 - `wt` command-line can't consistently parse more than one arg
Presently, the Terminal just arbitrarily dispatches a bunch of handlers
to try and handle all the commands provided on the commandline. That's
lead to a bunch of reports that not all the commands will always get
executed, nor will they all get executed in the same order.
This PR also changes the `TerminalPage` to be able to dispatch all the
commands sequentially, all at once in the startup. No longer will there
be a hot second where the commands seem to execute themselves in from of
the user - they'll all happen behind the scenes on startup.
This involved a couple other changes areound the `TerminalPage`
* I had to make sure that panes could be opened at a 0x0 size. Now they
use a star sizing based off the percentage of the parent they're
supposed to consume, so that when the parent _does_ get laid out,
they'll take the appropriate size of that parent.
* I had to do some math ahead of time to try and calculate what a
`SplitState::Automatic` would be evaluated as, despite the fact that
we don't actually know how big the pane will be.
* I had to ensure that `focus-tab` commands appropriately mark a single
tab as focused while we're in startup, without roundtripping to the
Dispatcher thread and back
## References

helpful for this PR.
## Detailed Description of the Pull Request / Additional comments
`CascadiaSettings::BuildSettings` can throw if the GUID doesn't exist.
This wraps those calls up with a try/catch.
It also adds a couple tests - a few `SettingsTests` for try/catching
this state. It also adds a XAML-y test in `TabTests` that creates a
`TerminalPage` and then performs som UI-like actions on it. This test
required a minor change to how we generate the new tab dropdown - in the
tests, `Application::Current()` is _not_ a `TerminalApp::App`, so it
doesn't have a `Logic()` to query. So wrap that in a try/catch as well.
While working on these tests, I found that we'd crash pretty agressively
for mysterious reasons if the TestHostApp became focused while the test
was running. This was due to a call in
`TSFInputControl::NotifyFocusEnter` that would callback to
`TSFInputControl::_layoutRequested`, which would crash on setting the
`MaxSize` of the canvas to a negative value. This PR includes a hotfix
for that bug as well.

* A double left click will always begin a word selection
* A triple left click will always begin a line selection
* A selection will only truly start when the cursor moves a quarter of
the smallest dimension of a cell (usually its width) in any direction
_This eliminates the selection of a single cell on one click._

* We now keep track of whether the selection has been "copied", or
"updated" since it was last copied. If an endpoint moves, it is

(#4740)
Because of this, we can stop tracking the position of the focus-raising
click, and whether it was part of click-drag operation. All clicks can
_become_ part of a click-drag operation if the user drags.
We can also eliminate the special handling of single cell selection at
the TerminalCore layer: since TermControl determines when to begin a
selection, TerminalCore no longer needs to know whether copy on select
is enabled _or_ whether the user has started and then backtracked over a
single cell. This is now implicit in TermControl.

## Details `std::vector<bool>` provided by the Microsoft VC Runtime is
incapable of a great many things. Many of the methods you come to expect
off of `std::vector<T>` that are dutifully presented through the `bool`
variant will spontaneously fail at some future date because it decides
you allocated, resized, or manipulated the `vector<bool>` specialization
in an unsupported manner. Half of the methods will straight up not work
for filling/resizing in bulk. And you will tear your hair out as it will
somehow magically forget the assignment of half the bits you gave it
part way through an iteration then assert out and die.
As such, to preserve my sanity, I searched for an alternative. I came
across the self-contained header-only library `dynamic_bitset` by
@pinam45 which appears to do as much of `boost::dynamic_bitset` as I
wanted, but without including 400kg of boost libraries. It also has a
nifty optional dependency on `libpopcnt` by @kimwalisch that will use
processor-specific extensions for rapidly counting bits. @DHowett-MSFT
and I briefly discussed how nice `popcnt` would have been on
`std::vector<bool>` last week... and now we can have it. (To be fair, I
don't believe I'm using it yet... but we'll be able to easily dial in
`til::bitmap` soon and not worry about a performance hit if we do have
to walk bits and count them thanks to `libpopcnt`.)
This PR specifically focuses on swapping the dependencies out and
ingesting the new libraries. We'll further tune `til::bitmap` in future
pulls as necessary.
## Validation
* [x] Ran the automated tests for bitmap.
* [x] Ran the terminal manually and it looks fine still.
## Summary of the Pull Request
This PR fixes an out of bounds access when deleting composition during Chinese IME. What's happening is that we're receiving a CompositionCompleted before receiving the TextUpdate to tell us to delete the last character in the composition. This creates two problems for us:
1. The final character gets sent to the Terminal when it should have been deleted.
2. `_activeTextStart` gets set to `_inputBuffer.length()` when sending the character to the terminal, so when the `TextUpdate` comes right after the `CompositionCompleted` event, `_activeTextStart` is out of sync.
This PR fixes the second issue, by updating `_activeTextStart` during a `TextUpdate` in case we run into this issue.
The first issue is trickier to resolve since we assume that if the text server api tells us a composition is completed, we should send what we have. It'll be tracked here: #5110.
At the very least, this PR will let users continue to type in Chinese IME without it breaking, but it will still be annoying to see the first letter of your composition reappear after deleting it.

This commit upgrades C++/WinRT to 2.0.200316.3 and fixes a couple of the
transitive dependency issues we had in the process.
Because the latest version has better dependency resolution, we're able
to properly depend on Microsoft.UI.Xaml and the Toolkit in TerminalApp
and TerminalAppLib so we no longer need to manually include .dll and
.pri files.
Because of nebulous _other_ changes in dependency resolution,
WindowsTerminalUniversal isn't picking up transitive .winmd dependencies
from TerminalApp, and needs to include them as ProjectReferences
directly. This was already happening transitively, so now it's explicit.
I've also taken the time to upgrade GSL to v2.1.0, the last release
before they removed span::at and blew up our world.

## Detailed Description of the Pull Request / Additional comments
- Converted `GetDirtyArea()` interface from `IRenderEngine` to use a vector of `til::rectangle` instead of the `SMALL_RECT` to banhammer inclusive rectangles.
- `VtEngine` now holds and operates on the `til::bitmap` for invalidation regions. All invalidation operation functions that used to be embedded inside `VtEngine` are deleted in favor of using the ones in `til::bitmap`.
- Updated `VtEngine` tracing to use new `til::bitmap` on trace and the new `to_string()` methods detailed below.
- Comparison operators for `til::bitmap` and complementary tests.
- Fixed an issue where the dirty rectangle shortcut in `til::bitmap` was set to 0,0,0,0 by default which means that `|=` on it with each `set()` operation was stretching the rectangle from 0,0. Now it's a `std::optional` so it has no value after just being cleared and will build from whatever the first invalidated rectangle is. Complementary tests added.
- Optional run caching for `til::bitmap` in the `runs()` method since both VT and DX renderers will likely want to generate the set of runs at the beginning of a frame and refer to them over and over through that frame. Saves the iteration and creation and caches inside `til::bitmap` where the chance of invalidation of the underlying data is known best. It is still possible to iterate manually with `begin()` and `end()` from the outside without caching, if desired. Complementary tests added.
- WEX templates added for `til::bitmap` and used in tests.
- `translate()` method for `til::bitmap` which will slide the dirty points in the direction specified by a `til::point` and optionally back-fill the uncovered area as dirty. Complementary tests added.
- Moves all string generation for `til` types `size`, `point`, `rectangle`, and `some` into a `to_string` method on each object such that it can be used in both ETW tracing scenarios AND in the TAEF templates uniformly. Adds a similar method for `bitmap`.
- Add tagging to `_bitmap_const_iterator` such that it appears as a valid **Input Iterator** to STL collections and can be used in a `std::vector` constructor as a range. Adds and cleans up operators on this iterator to match the theoretical requirements for an **Input Iterator**. Complementary tests added.
- Add loose operators to `til` which will allow some basic math operations (+, -, *, /) between `til::size` and `til::point` and vice versa. Complementary tests added. Complementary tests added.
- Adds operators to `til::rectangle` to allow scaling with basic math operations (+, -, *) versus `til::size` and translation with basic math operations (+, -) against `til::point`. Complementary tests added.
- In-place variants of some operations added to assorted `til` objects. Complementary tests added.
- Update VT tests to compare invalidation against the new map structure instead of raw rectangles where possible.
## Validation Steps Performed
- Wrote additional til Unit Tests for all additional operators and functions added to the project to support this operation
- Updated the existing VT renderer tests
- Ran perf check

## Summary of the Pull Request
Currently, if the Terminal attempts to parse a setting that _should_ be a `bool`
and the user provided a string, then we'll throw an exception while parsing the
settings, and display an error message that's pretty unrelated to the actual
problem.
The same goes for `bool`s as `int`s, `float`s as `int`s, etc.
This PR instead updates our settings parsing to ensure that we check the type of
a json value before actually trying to get its parsed value.

These projects load Xaml components that have Uids, but those Uids just
weren't working because Xaml components are, by default, loaded in
"Application" scope. Application scope is great if the resource producer
is the EXE project.
Application scope means that resources are looked up at the resource
root, but DLLs with resources don't produce resources at the root. They
produce resources at a root named after the DLL.
Setting the Xaml component resource location to Nested makes sure the
Xaml resource loader loads resources from the right places.
## Summary of the Pull Request
This PR turns on TextWrapping on `TSFInputControl::TextBlock`. Once the TextBlock hits the end of the Terminal window, it will wrap downwards, but the TextBlock will have as much width as it had when composition started. Unfortunately, this means if composition starts right at the end of the Terminal with enough width for just one character, there will be a vertical line of characters down the right side of the Terminal 😅. It's definitely not ideal, and I imagine this won't be the last time we visit this issue, but for now users can see what they're typing.

## Summary of the Pull Request
Alt-Numpad# input would be escaping each numkey before sending it through. This would result in some weird behavior, for example, in powershell, where the first alt-numpad# would start digit argument and once the user releases alt, a character is sent through and digit argument would repeat that character X times. To resolve this, we simply need to ignore KeyDowns where Alt is held and a Numpad# is pressed.
Once Alt is released, we'll receive a character through `TSFInputControl`, not `TermControl::CharacterHandler`. It seems that the `CoreTextEditContext` in `TSFInputControl` intercepts the character before it gets to `TermControl`. TSF will then send the received character through as normal.

We (the royal "we") broke key unbinding in #4746. We didn't run the local tests after this, which actually would have caught this. The comment even suggests what we should have done here. We need to make sure that when we bail, it's because there's a parsing function that returned nothing. `null`, `"unbound"`, etc actually don't even have a parsing function at all, so they should just keep on keepin' on.

Add the option to set the cursor color as part of the color scheme.
This is very useful for light themes, where the cursor disappears unless its color
is set in the profile.
Related to issue #764, but doesn't fully resolve it.
## Validation
I tested this manually by creating a light color scheme, setting the cursor color
to black and setting the profile color scheme to the newly created color scheme.
I validated the cursor is black, then set the cursor color in the profile (to red)
and saw it trumps the cursor color from the color scheme.
When WSL.exe would hang for users, WslDistroGenerator would also hang
while waiting for its `wsl.exe --list` call to return. The timeout was
`INFINITE` in the `WaitForSingleObject` call, but we should slap a
timeout on it instead (here we choose 2 seconds). In addition, if it
times out, we should also just return profiles and let the Terminal
continue to start up without the WSL distro profiles loaded.

Made a sleep 30 executable as the command instead, made sure it hit the
`WAIT_TIMEOUT` and continued to start up without loading my Ubuntu

`\x1b[3J`. I didn't realize at the time that #2715 was mostly about hard reset,

We already hated the `std::optional<short>&` thing I yeet'd into #4741 right at the end to replace a `short*`. So I was already going to change that to a `std::optional<std::reference_wrapper<short>>`, which is more idomatic. But then I was looking through the list of bugs and #3494 caught my eye. I realized it would be trivial to not only track the top of the `mutableViewport` during a resize, but we could use the same code path to track the _visible_ viewport's start as well.
So basically I'm re-using that bit of code in `Reflow` to calculate the visible viewport's position too.

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

cmatrix is somewhat of a pathological case for our infrastructure: it
prints out a bunch of green and white characters and then updates them a
million times a second.
It also maintains a column of space between every green character. When
it prints this column, it prints it in "default" or "white". This ends
up making runs of text that look like this:
(def: G=green B=bright white W=white *=matrix char =space)
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W

G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
G W G W G W G W G W G W G W G W
As characters trickle in:
G*W G*W G*W G*W G*W G*W G*W B*W
G*W G*W G*W G*W G*W G*W G*W G W

Every one of those color transitions causes us to break up the run of
text and start rendering it again. This impacts GDI, Direct2D *and*
ConPTY. In the example above, there are 120 runs.
The problem is, printing a space doesn't **use** the foreground color!
This commit introduces an optimization. When we're about to break a text
cluster because its attributes changed, we make sure that it's not just
filled with spaces and doesn't differ in any visually-meaningful way
(like underline or strikethrough, considering global invert state).
This lets us optimize both the rendering _and_ the PTY output to look
like this:
G* * * * * * * B*G
G* * * * * * *
G* * * B*G * * *
G* B*G * * * * *
G* * * B*G * *
B*G * * B*G *
G * * B*G
G B*G *
Text will be printed at best line-by-line and at worst only when the
visible properties of the screen actually change. In the example
above, there are only 21 runs.
This speeds up cmatrix remarkably.

## Validation Steps Performed
Tests should still pass.
This PR adds support for "Resize with Reflow" to the Terminal. In
conhost, `ResizeWithReflow` is the function that's responsible for
reflowing wrapped lines of text as the buffer gets resized. Now that
#4415 has merged, we can also implement this in the Terminal. Now, when
the Terminal is resized, it will reflow the lines of it's buffer in the
same way that conhost does. This means, the terminal will no longer chop
off the ends of lines as the buffer is too small to represent them.
As a happy side effect of this PR, it also fixed#3490. This was a bug
that plagued me during the investigation into this functionality. The
original #3490 PR, #4354, tried to fix this bug with some heavy conpty
changes. Turns out, that only made things worse, and far more
complicated. When I really got to thinking about it, I realized "conhost
can handle this right, why can't the Terminal?". Turns out, by adding
resize with reflow, I was also able to fix this at the same time.
Conhost does a little bit of math after reflowing to attempt to keep the
viewport in the same relative place after a reflow. By re-using that
logic in the Terminal, I was able to fix#3490.
I also included that big ole test from #3490, because everyone likes
adding 60 test cases in a PR.

## EDIT: Changes to this PR on 5 March 2020
I learned more since my original version of this PR. I wrote that in
January, and despite my notes that say it was totally working, it
_really_ wasn't.
Part of the hard problem, as mentioned in #3490, is that the Terminal
might request a resize to (W, H-1), and while conpty is preparing that
frame, or before the terminal has received that frame, the Terminal
resizes to (W, H-2). Now, there aren't enough lines in the terminal
buffer to catch all the lines that conpty is about to emit. When that
happens, lines get duplicated in the buffer. From a UX perspective, this
certainly looks a lot worse than a couple lost lines. It looks like
utter chaos.
So I've introduced a new mode to conpty to try and counteract this
behavior. This behavior I'm calling "quirky resize". The **TL;DR** of
quirky resize mode is that conpty won't emit the entire buffer on a
resize, and will trust that the terminal is prepared to reflow it's
buffer on it's own.
This will enable the quirky resize behavior for applications that are
prepared for it. The "quirky resize" is "don't `InvalidateAll` when the
terminal resizes". This is added as a quirk as to not regress other
terminal applications that aren't prepared for this behavior
(gnome-terminal, conhost in particular). For those kinds of terminals,
when the buffer is resized, it's just going to lose lines. That's what
currently happens for them.
When the quirk is enabled, conpty won't repaint the entire buffer. This
gets around the "duplicated lines" issue that requesting multiple
resizes in a row can cause. However, for these terminals that are
unprepared, the conpty cursor might end up in the wrong position after a
quirky resize.
The case in point is maximizing the terminal. For maximizing
(height->50) from a buffer that's 30 lines tall, with the cursor on
y=30, this is what happens:
* With the quirk disabled, conpty reprints the entire buffer. This is
60 lines that get printed. This ends up blowing away about 20 lines
of scrollback history, as the terminal app would have tried to keep
the text pinned to the bottom of the window. The term. app moved the
viewport up 20 lines, and then the 50 lines of conpty output (30
lines of text, and 20 blank lines at the bottom) overwrote the lines
from the scrollback. This is bad, but not immediately obvious, and
is **what currently happens**.
* With the quirk enabled, conpty doesn't emit any lines, but the
actual content of the window is still only in the top 30 lines.
However, the terminal app has still moved 20 lines down from the
scrollback back into the viewport. So the terminal's cursor is at
y=50 now, but conpty's is at 30. This means that the terminal and
conpty are out of sync, and there's not a good way of re-syncing
these. It's very possible (trivial in `powershell`) that the new
output will jump up to y=30 override the existing output in the
terminal buffer.
The Windows Terminal is already prepared for this quirky behavior, so it
doesn't keep the output at the bottom of the window. It shifts it's
viewport down to match what conpty things the buffer looks like.
What happens when we have passthrough mode and WT is like "I would like
quirky resize"? I guess things will just work fine, cause there won't be
a buffer behind the passthrough app that the terminal cares about. Sure,
in the passthrough case the Terminal could _not_ quirky resize, but the
quirky resize won't be wrong.
When ConPTY encounters a string we don't understand, immediately flush the frame.

For the tabs below the titlebar case, there's 6px (unscaled) of space that I cannot account for. I seriously have no idea where it's coming from. When we end up creating the first `TermControl` after startup, there's an inexplicable `6*scale` difference between the height of the `tabContent` and the `SwapChainPanel`'s size.
## Validation Steps Performed

There's a platform limitation that causes us to crash when we rearrange
tabs. Xaml tries to send a drag visual (to wit: a screenshot) to the
drag hosting process, but that process is running at a different IL than
us.
For now, we're disabling elevated drag.

I noticed a crash in debug builds when a connected application terminates;
we get its exit code, then we destruct, and the u16state is used after it's
destructed by us parsing the process's last words.
We should have been doing this all along.

## Summary of the Pull Request
I originally thought that setting `TSFInputControl::_editContext.InputPaneDisplayPolicy` to be Automatic would allow the InputPanel to show and hide automatically when `TSFInputControl` gains and loses focus. It doesn't seem to behave that way, so we'll show the InputPanel manually.
I'll show the panel during `PointerPressedHandler` and during `GotFocusHandler`. A user will have the on-screen keyboard pop up when getting focus, but if they close the keyboard, they can simply re-tap on the terminal to bring it back up.

Note to future code archeologists:
This doesn't seem to work for fullscreen on the primary display. However, testing a bunch of other apps with fullscreen modes and an auto-hiding taskbar has shown that _none_ of them reveal the taskbar from fullscreen mode. This includes Edge, Firefox, Chrome, Sublime Text, Powerpoint - none seemed to support this.
This does however work fine for maximized.

## Validation Steps Performed
These are the scenarios I've tested. They're a combination of in focus/out of focus, Copy On Select on/off, left/right click pressed and their move and release variants.
From Out of Focus:
- Left Click = Focus
- Left Click Move = Focus + Selection
- Left Click Release
- CoS on = Copy
- CoS off = Nothing
- Shift Left Click = Focus
- Right Click
- Focus
- CoS on = Paste
- CoS off = Copy if Active Selection, Paste if not.
- Right Click Move = Nothing
- Right Click Release = Nothing
From In Focus
- Left Click = Selection if CoS off
- Left Click Move = Selection
- Left Click Release
- CoS on = Copy
- CoS off = Nothing
- Shift Left Click = Set Selection Anchor
- Right Click
- CoS on = Paste
- CoS off = Copy if Active Selection, Paste if not.
- Right Click Move = Nothing
- Right Click Release = Nothing
checkpointing this since it's so close. It works for everything but fullscreen on my primary, 125% display which has the taskbar on top, and autohides. Every other case works fine.

Add a `SizeChanged` handler to the titlebar content UI element. It's possible that this element's size will change after the dragbar's. When that happens, the drag bar won't send another `SizeChanged` event, because the dragbar's _size_ didn't change, only it's position.

## Summary of the Pull Request
Emoji composition was only being shown one letter at a time. This is because of the way I expected `CoreTextTextUpdatingEventArgs.Range` to be provided to TSFInputControl during composition (for Chinese/Japanese IME). Emoji IME composition gives the `StartCaretPosition` as the same as `EndCaretPosition`, unlike how for Chinese/Japanese IME, `StartCaretPosition` is usually the start of the composition and `EndCaretPosition` is the latest character in the composition. The solution is to change the `_inputBuffer.substr()` call to simply grab all of the buffer starting from `_activeTextStart`. This way I can ensure that I grab all of the "active text", instead of trusting the given `args.Range` to tell me the active text.

## Summary of the Pull Request
`GetTextForClipboard` already exists in the TextBuffer. It makes sense to use that for UIA as well. This changes the behavior or `GetText()` such that it does not remove leading/trailing whitespace anymore. That is more of an expected behavior.

This also contributes to...

Now that the expansion occurs at before render-time, the selection anchors are an accurate representation of what is selected. We just need to move GetText to the TextBuffer. Then we can have those three issues just rely on code from the text buffer. This also means ConHost gets some of this stuff for free 😀
## Detailed Description of the Pull Request / Additional comments

The Xaml input stack doesn't allow an application to suppress the "caret
browsing" dialog experience triggered when you press F7.
The official recommendation from the Xaml team is to catch F7 before we
hand it off.
This commit introduces a special F7 handler and an ad-hoc implementation of event bubbling.
Runtime classes implementing a custom IF7Listener interface are
considered during a modified focus parent walk to determine who can
handle F7 specifically.
If the recipient control handles F7, we suppress the message completely.
This event bubbler has some minor issues -- the search box will not be
able to receive F7 because its parent control implements the handler.
Since search is already mostly a text box, it doesn't _need_ special
caret browsing functionality as far as I can tell.
TermControl implements its OnF7Pressed handler by synthesizing a
keybindings event and an event to feed into Terminal Core directly.
It's not possible to create a synthetic KeyPressRoutedEvent; if it were,
I would have just popped one into the traditional input queue. :)
Fixes#638.
## Summary of the Pull Request
Korean IME was not working correctly due to way we were clearing the input buffer inside of `TSFInputControl`. We wanted to clear our input buffer and tell TSF to clear its input buffer as well when we receive a `CompositionCompleted` event. This works fine in some IME languages such as Chinese and Japanese. However, Korean IME composes characters differently in such a way where we can't tell TSF to clear their buffer during a `CompositionCompleted` event because it would clear the character that triggered the `CompositionCompleted` event in the first place.
The solution in this PR is to keep our `_inputBuffer` intact until the user presses <kbd>Enter</kbd> or <kbd>Esc</kbd>, in which case we clear our buffer and the TSF buffer. I've chosen these two keys because it seems to make sense to clear the buffer after text is sent to the terminal with <kbd>Enter</kbd>, and <kbd>Esc</kbd> usually means to cancel a current composition anyway.
This means we need to keep track of our last known "Composition Start Point", which is represented by `_activeTextStart`. Whenever we complete a composition, we'll send the portion of the input buffer between `_activeTextStart` and the end of the input buffer to the terminal. Then, we'll update `_activeTextStart` to be the end of the input buffer so that the next time we send text to the terminal, we'll only send the portion of our buffer that's "active".

* Azure: rewrite user input handler
This commit replaces the AzureConnection's input handler with one that
acts more like "getline()". Instead of the Read thread setting a state
and WriteInput filling in the right member variable, the reader blocks
on the user's input and receives it in an optional<string>.
This moves the input number parsing and error case handling closer to
the point where those inputs are used, as opposed to where they're
collected.
It also switches our input to be "line-based", which is a huge boon for
typing tenant numbers >9. This fixes#3233. A simple line editor
(supporting only backspace and CR) is included.
It also enables echo on user input, and prints it in a nice pretty green
color.
It also enables input queueing: if the user types anything before the
connection is established, it'll be sent once it is.
Fixes#3233.
* Azure: display the user's options and additional information in color
This commit colorizes parts of the AzCon's strings that include "user
options" -- things the user can type -- in yellow. This is to help with
accessibility.
The implementation here is based on a discussion with the team.
Alternative options for coloration were investigated, such as:
* Embedding escape sequences in the resource file.
This would have been confusing for translators.
The RESW file format doesn't support  escapes, so we would need
some magic post-processing.
* Embedding "markup" in the resource file (like #{93m}, ...)
This still would have been annoying for translators.
We settled on an implementation that takes resource names, colorizes
them, and string-formats them into other resources.
* Azure: follow the user's shell choice from the online portal
Fixes#2266.
* Azure: remove all credentials instead of just the first one

## Detailed Description of the Pull Request / Additional comments
I started with the following implementation:
When conpty is about to write the last column, note that we wrapped this line here. If the next character the vt renderer is told to paint get is supposed to be at the start of the following line, then we know that the previous line had wrapped, so we _won't_ emit the usual `\r\n` here, and we'll just continue emitting text.
However, this isn't _exactly_ right - if someone fills the row _exactly_ with text, the information that's available to the vt renderer isn't enough to know for sure if this line broke or not. It is possible for the client to write a full line of text, with a `\n` at the end, to manually break the line. So, I had to also add the `lineWrapped` param to the `IRenderEngine` interface, which is about half the files in this changelist.
## Validation Steps Performed
* Ran tests
* Checked how the Windows Terminal behaves with these changes
* Made sure that conhost/inception and gnome-terminal both act as you'd expect with wrapped lines from conpty
This commit removes all of the custom UI initialization code in
TermControl and replaces it with a xaml file. Some dead or reundant code
was removed as part of this refactoring.
It also fixes two (quasi-related) issues:
* The search box, on first launch, was offset by the scrollbar even if
the scrollbar was invisible.
* The scrollbar state wasn't hot-reloadable.
The new UIA code in PublicTerminalCore broke windows 7 support by referring
to API set dlls for UIA. This PR changes the link line to link to
UIAutomationcore.dll directly.
## Summary of the Pull Request
Currently, when the user attempts to type using IME while the Search Box is focused, the input goes to the terminal instead. This is due to the fact that the `TSFInputControl` assumes it's in control whenever TermControl gets focus. So, it'll intercept IME input before the Search Box receives it. We simply need to modify `TermControl::GotFocus` to check if the SearchBox has focus. If it does, `TSFInputControl::NotifyFocusEnter` shouldn't be called.
As a small side fix, I've also disabled the terminal cursor blinking when the Search Box has focus.
Thinking a little further, if we have more features in the future that behave like search box (i.e. advanced tab switcher, or any other XAML controls that pop up) and require text input, we might need to create a sort of "AnyOtherTextControlInFocus" function to see if TSFInputControl should receive focus or not.

## Validation Steps Performed
Search works as expected with IME. Composition picker appears underneath Search Box when typing IME in the Search Box. Clicking outside of the Search Box still returns control to TSFInputControl/TermControl.
Terminal Cursor blinks when it has focus, and doesn't when the Search Box has focus.
## Summary of the Pull Request
Currently, while in IME mode, selections with the Emoji/Kaomoji/Symbol Picker (which is brought up with <kbd>win+.</kbd>) are not displayed until the user starts a new composition. This is due to the fact that we hide the TextBlock when we receive a CompositionCompleted event, and we only show the TextBlock when we receive a CompositionStarted event. Input from the picker does not count as a composition, so we were never showing the text box, even if the symbols were thrown into the inputBuffer. In addition, we weren't receiving CompositionStarted events when we expected to.
We should be showing the TextBlock when we receive _any_ text, so we should make the TextBlock visible inside of `TextUpdatingHandler`. Furthermore, some really helpful discussion in #3745 around wrapping the `NotifyTextChanged` call with a `NotifyFocusLeave` and a `NotifyFocusEnter` allowed the control to much more consistently determine when a CompositionStarted and a CompositionEnded.
I've also went around and replaced casts with saturating casts, and have removed the line that sets the `textBlock.Width()` so that it would automatically set its width. This resolves the issue where while composing a sentence, the textBlock would be too small to contain all the text, so it would be cut off, but the composition is still valid and still able to continue.

## Summary of the Pull Request
We used to return multiple text ranges to represent one selection. We only support one selection at a time, so we should only return one range.
Additionally, I moved all TriggerSelection() calls to the renderer from Terminal to TermControl for consistency. This ensures we only call it _once_ when we make a change to our selection state.

## Summary of the Pull Request
Currently, clicking on an unfocused terminal with a selection active will trigger `copyOnSelect`. This is because the check for `copyOnSelect` and copying to the clipboard is bound to when the Pointer is released. This works fine for when a user performs a click-drag selection, but it inadvertently also triggers when the user performs a single click on an unfocused terminal. We expect `copyOnSelect` to trigger only on the first time a selection is completed.
This PR will allow the user to single click on an unfocused terminal that has a selection active without triggering a copyOnSelect. It also ensures that any click-drag selection, whether it's on an unfocused or focused terminal, will trigger copyOnSelect.

the current scrolling value from `GetScrollOffset`, which is already
rounded in `int`, let the scrolling operation to operate on
`_scrollBar`'s `Value` directly (which uses `double`) in
`TermControl.cpp`.
TermControl now also respects WHEEL_DELTA, which it was previously
ignoring, to determine how many scroll wheel detents were used.
Testing scrolling on the following scenario manually:
- nonscrollable terminal (e.g. the window is large enough to contain the
current buffer).
- scrolling to the topmost and bottom-most.
- scrolling TUI apps such as `nano` and `more` in WSL.
- after clearing the terminal, both in cmd and WSL.
... has the same behavior between using touchscreen or precision trackpad
and regular mouse wheel.

## Summary of the Pull Request
The issue seems to be how `SwapChainScaleChanged` gets fired and attempts to tell the renderer
to `UpdateDPI` when the renderer is gone. So, as a quick bandaid, we'll put a quick check to only do the thing if the renderer is alive.

## Summary of the Pull Request
This PR tries to address some of the weird interactions with pointer pressed events when the Terminal isn't in focus. Here's the four things that have changed as part of this PR;
1. This PR will allow the user to be able to make a selection with a click-drag without having to first perform a single click on a tab/pane to bring it to focus.
2. Another weird bug that's fixed in this PR is where trying to make a selection on an unfocused tab when it already has a selection active will simply extend the existing selection instead of making a new one.
3. Not related to the issue that his PR closes: a right click will now focus the tab/pane.
I've made sure that we still have the existing functionality where a single click on an unfocused tab/pane does not make a single-cell selection and just focuses the tab/pane.

## Validation Steps Performed
Played around with all sorts of selection when in-focus and out of focus with multiple panes and tabs.
Unit tests still pass as well.
This will attempt to match the style of the user's JSON.
Caveats:
1. If the user has no profiles, it'll explode. This isn't new.
2. If the user's indentation style if `{profile}, {profile}, {profile}` (that is: no indentation), you'll get this:
```
{profile}, {profile}, {profile},
{
new profile content
}
```
There may be something better we can do by copying their newline (or lack thereof) and using it in our generator or detecting the indentation of their members as well.
That's an exercise for later.

## Detailed Description of the Pull Request / Additional comments
The following data is collected with examples of the types of questions we intend to answer:
1. What is the name of the executable attached to the PTY? (What shells are popular? Should we focus our testing on them? Are there any common ones we are blind to that we should know about?)
- "Microsoft.Windows.Terminal.Connection" {e912fe7b-eeb6-52a5-c628-abe388e5f792}
- "ConPtyConnected" event
- "SessionGuid" value = WT_SESSION
- "Client" value = Name of EXE
2. Is Acrylic used on a tab? And with what opacity? (Do people really want acrylic? Should it be default? What opacity is most pleasing in our context?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "TabInformation" event
- "EventVer" value is now 1u
- "UseAcrylic" value is now TRUE/FALSE on the setting choice
- "TintOpacity" value is now Float on the setting choice
3. What font are people choosing? (Do people move away from Cascadia Code? Which ones are the most popular for us to validate when updating the renderer?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "TabInformation" event
- "FontFace" value is now string font from settings
4. What keybindings do people choose to customize (Add or Remove)? (Are there extremely common keys that folks bind or unbind that we should have adjusted by default in a fresh install?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "CustomKeybindings" event
- "Keybindings" value is the entire JSON segment that describes the user keybindings from `settings.json`.
5. Do people change their default profile from the PowerShell one we set? If so, to what? (Should we not set PowerShell as the default? Should we adjust the ranking of our dynamic generators to favor the most popular ones to bubble to the top?)
- "Microsoft.Windows.Terminal.App" {24a1622f-7da7-5c77-3303-d850bd1ab2ed}
- "CustomDefaultProfile" event
- "DefaultProfile" value is the GUID of the chosen profile
## Validation Steps Performed
1. Implemented the events
2. Launched the ETL channel viewer
3. Triggered the events
4. Saw the data come out
The Terminal would crash when closing it when there are multiple tabs
open. This was due to `TerminalPage` attempting to select a nonexistent
tab.
The block of code that was removed was causing issues when trying to
close all tabs at once. The way we close all our tabs in
`_CloseAllTabs()` was by repeatedly calling
`_RemoveTabViewItemByIndex(0)` until `_tabs.Size() == 0`. The problem
was that `_RemoveTabViewItemByIndex` would eventually call a coroutine
to set the next tab as the `SelectedItem` after removing a tab. The
coroutine would then pass control back to `_CloseAllTabs()` to finish
its loop, and by the time the coroutine resumes control, `_tabs` and
`TabView().TabItems()` would both be empty and it would crash attempting
to focus a tab.
Luckily, the functionality that this block of code provided is really no
longer needed . This code was used to focus on the next tab after
closing a tab. This might have been written way back when TabView
didn't have this functionality built in. It seems now that after
removing a `TabItem` from the `TabView`, the `SelectedItem` of the
TabView automatically updates, making this block of code unnecessary.
## Validation Steps Performed
Did a lot of multiple tab open and closings and closing the window after
opening a ton of tabs. No crashes seem to occur anymore!
Test cases still pass.
Closes#4482
The UIA Provider now scrolls the viewport when necessary. This just fills in the missing virtual function in Terminal to have the same behavior as what it does in ConHost.
* [X] Closes#2361
* [X] CLA signed.
`ChangeViewport` is now a virtual function at the `ScreenInfoUiaProvider` layer to have access to the TermControl.
In ConHost, we pass this call up to the WindowUiaProvider layer. In Terminal, we don't need to do that because the concept of updating the viewport is handled at the TermControl layer. So we just call that function and _voila_!

Tested on 200% display and 100% display. Rects are aligned on both.
## Summary of the Pull Request
This is a fix that technically was caused by #357, though we didn't have the Terminal at the time, so I only fixed conhost then. When a client app prints the very last column in the buffer, the cursor is often not _actually_ moved to the next row quite yet. The cursor usually just "floats" on the last character of the row, until something happens. This could be a printable character, which will print it on the next line, or a newline, which will move the cursor to the next line manually, or it could be a backspace, which might take the cursor back a character.
Conhost and gnome-terminal behave slightly differently here, and wt behaves differently all together. Heck, conhost behaves differently depending on what output mode you're in.
The scenario in question is typing a full row of text, then hitting backspace to erase the last char of the row.
What we were emitting before in this case was definitely wrong - we'd emit a space at that last row, but then not increment our internal tracker of where the cursor is, so the cursor in conpty and the terminal would be misaligned. The easy fix for this is to make sure to always update the `_lastText` member appropriately. This is the `RightExclusive` change.
The second part of this change is to not be so tricksy immediately following a "delayed eol wrap". When we have just printed the last char like that, always use the VT sequence CUP the next time the cursor moves. Depending on the terminal emulator and it's flags, performing a BS in this state might not bring the cursor to the correct position.

## Detailed Description of the Pull Request / Additional comments
There are two ways scroll can happen:
- the user scrolls using the scroll bar and the `Terminal` is notified
- the `Terminal` changed the viewport and the scroll bar is updated to reflect the change
The code to notify the `Terminal` that the user scrolled is in the event handler for when the scroll bar's value changes. However this poses a problem because it means that when the `Terminal` changes the viewport, the scroll bar is updated so it would then also notify the `Terminal` that the scroll changed. But it already knows because it's coming from itself!
To fix this, the `TermControl` class had a member called `_lastScrollOffset` that would be set when the `Terminal` decides to change the viewport so that the event handler for the scroll bar could check the new scroll value against `_lastScrollOffset` and if it matches, then everything is fine and there is nothing to update.
This is what happens when the `Terminal` changes the viewport:
1. set `_lastScrollOffset`
2. dispatch job on the UI thread: update the scrollbar which is going to call the event handler which is going to check for `_lastScrollOffset` and clear it
There are two bugs introduced by this approach:
1. (I am not sure about this.) The dispatcher appears to store jobs in a LIFO stack so it sometimes reorders the "update the scrollbar" jobs when there are too many. When I run `1..10000` on PowerShell, then I get this from the event handler (format: `_lastScrollOffset newValue`):
```
8988 8988
8989 8989
8990 8990
8992 8991
8993 8992
...
9001 8997
9001 8998
9001 8999
9001 9000
9001 9001
9001 8985
9001 8968
9001 8953
...
9001 7242
9001 7226
9001 7210
```
This causes the following issues:
1. `_lastScrollOffset` wouldn't be reset because it wouldn't be equal to the current scroll bar value (see example above) so the next scrolls wouldn't do anything as the event handler would still be waiting for an event with the good scroll bar value which would never happen because it happened earlier
2. the `TermControl` would notify the `Terminal` about its own scroll
2. If the `Terminal` didn't actually changed its viewport but still called the `TermControl::_TerminalScrollPositionChanged` method, then it would set the `_lastScrollOffset` member as usual but the scroll bar value change event handler would not be called because it is only called when the value actually changes so the `_lastScrollOffset` member wouldn't be cleared and subsequent scroll bar value change events would be ignored because again the event handler would still be waiting for an event with the good scroll bar value which would never happen. This is actually the reason for #1494: when the window is resized, the `Terminal` will call `TermControl::_TerminalScrollPositionChanged` even if the scroll position didn't actually change (444de5b166/src/cascadia/TerminalCore/Terminal.cpp (L183)). Maybe this should also be fixed in another PR?
I replaced `_lastScrollOffset` by a flag `_isTerminalInitiatedScroll`. I set the flag just before and unset it just after the terminal changes the scrollbar on the UI thread to eliminate the race conditions and the bug when the scroll bar's value doesn't actually change.
Other changes:
- I also fixed a potential bug where if the user scrolls just after the terminal updates the viewport, it would en up ignoring the user scroll. To do this, when the user scrolls, I cancel any update with `_willUpdateScrollBarToMatchViewport`.
- I also removed the original `ScrollViewport` method because it was not used anywhere and I think it can potentially create confusion (and therefore bugs) because this method updates the viewport but not the scroll bar unlike `KeyboardScrollViewport` which functions as you would expect. I then renamed `KeyboardScrollViewport` into `ScrollViewport`. So, now, there is only one method to scroll the viewport from the `TermControl`. Please, tell me if this shouldn't be in this PR.
- I also removed `_terminal->UserScrollViewport(viewTop);` in the `KeyboardScrollViewport` method because it will be updated later anyways in the scroll bar's value change event handler because of the `_scrollBar.Value(viewTop);`.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
## Validation Steps Performed
I tested manually by doing this:
- For bug 1:
1. Start the terminal
2. Run the `1..30000` command in PowerShell and wait for it to end (maybe more if you have a fast computer?)
3. Hold left click on the scrollbar slider and start moving it
- For bug 2:
1. Start the terminal
2. Run the `1..100` command in PowerShell and wait for it to end
3. Resize the window horizontally
4. Hold left click on the scrollbar slider and start moving it
Without this patch, the viewport doesn't update.
With the patch, the viewport updates correctly.

## Summary of the Pull Request
Conpty doesn't need `CSI 3 J`, it doesn't have a scrollback. The terminal that's connected should use that. This makes conpty pass it through, like other sequences that conpty has no need for.

## Summary of the Pull Request
This PR will make the existing `Tab` class into a WinRT type. This will allow any XAML to simply bind to the `ObservableVector` of Tabs.
This PR will be followed up with a future PR to change our TabView to use the ObservableVector, which will in turn eliminate the need for maintaining two vectors of Tabs. (We currently maintain `_tabs` in `TerminalPage` and we also maintain `TabView().TabViewItems()` at the same time as described here: #2740)

## Detailed Description of the Pull Request / Additional comments
I've currently only exposed a Tab's Title and IconPath to keep things simple. I foresee XAML elements that bind to Tabs to only really need these two properties for displaying.
I've also converted `TerminalPage`'s `std::vector<std::shared_ptr> _tabs` into a `IObservableVector<winrt::TerminalPage::Tab> _tabs` just so that future PRs will have the ground set for binding to this vector of tabs.
## Validation Steps Performed
Played around with Tabs and Panes and all sorts of combinations of keybindings for interacting with tabs and dragging and whatnot, it all seemed fine! Tab Tests also all pass.
Moved `FindText` to `UiaTextRangeBase`. Now that Search is a shared component (thanks #3279), I can just reuse it basically as-is.
#3279 - Make Search a shared component
#4018 - UiaTextRange Refactor
I removed it from the two different kinds of UiaTextRange and put it in the base class.
I needed a very minor change to ensure we convert from an inclusive end (from Search) to an exclusive end (in UTR).
Worked with `FindText` was globally messed with in windows.h. So we had to do a few weird things there (thanks Michael).
No need for additional tests because it _literally_ just sets up a Searcher and calls it.
## Summary of the Pull Request
This pull request is intended to achieve the following goals...
1) reduce duplicate code
2) remove static functions
3) improve readability
4) improve reliability
5) improve code-coverage for testing
6) establish functioning text buffer navigation in Narrator and NVDA
This also required a change to the wrapper class `XamlUiaTextRange` that has been causing issues with Narrator and NVDA.
See below for additional context.

## Detailed Description of the Pull Request / Additional comments
### UiaTextRange
- converted endpoints into the COORD system in the TextBuffer coordinate space
- `start` is inclusive, `end` is exclusive. A degenerate range is when start == end.
- all functions are no longer static
- `MoveByUnit()` functions now rely on `MoveEndpointByUnit()` functions
- removed unnecessary typedefs like `Endpoint`, `ScreenInfoRow`, etc..
- relied more heavily on existing functionality from `TextBuffer` and `Viewport`
### XamlUiaTextRange
- `GetAttributeValue()` must return a special HRESULT that signifies that the requested attribute is not supported. This was the cause of a number of inconsistencies between Narrator and NVDA.
- `FindText()` should return `nullptr` if nothing was found. #4373 properly fixes this functionality now that Search is a shared module
### TextBuffer
- Word navigation functionality is entirely in `TextBuffer` for proper abstraction
- a total of 6 functions are now dedicated to word navigation to get a good understanding of the differences between a "word" in Accessibility and a "word" in selection
As an example, consider a buffer with this text in it:
" word other "
In selection, a "word" is defined as the range between two delimiters, so the words in the example include [" ", "word", " ", "other", " "].
In accessibility , a "word" includes the delimiters after a range of readable characters, so the words in the example include ["word ", "other "].
Additionally, accessibility word navigation must be able to detect if it is on the first or last word. This resulted in a slight variant of word navigation functions that return a boolean instead of a COORD.
Ideally, these functions can be consolidated, but that is too risky for a PR of this size as it can have an effect on selection.
### Viewport
- the concept of `EndExclusive` is added. This is used by UiaTextRange's `end` anchor as it is exclusive. To signify that the last character in the buffer is included in this buffer, `end` must be one past the end of the buffer. This is `EndExclusive`
- Since many functions check if the given `COORD` is in bounds, a flag must be set to allow `EndExclusive` as a valid `COORD` that is in bounds.
### Testing
- word navigation testing relies more heavily on TextBuffer tests
- additional testing was created for non-movement focused functions of UiaTextRange
- The results have been compared to Microsoft Word and some have been verified by UiAutomation/Narrator contacts as expected results.

Okay it was a little more complicated than that. I had `IslandWindow` handle the drop, which then raises a generic event for `AppHost` to handle. `AppHost` handles this by writing the path as input to the terminal, traversing `AppLogic`, `TerminalPage` and finally landing in `TermControl`

This PR removes all of the VT-specific functionality from the `WriteCharsLegacy` function that dealt with control characters, since those controls are now handled in the state machine when in VT mode.

## Detailed Description of the Pull Request / Additional comments
There are four changes to the `WriteCharsLegacy` implementation:
1. The `TAB` character had special case handling in VT mode which is now no longer required. This fixes a bug in the Python REPL editor (when run from a cmd shell in Windows Terminal), which would prevent you tabbing past the end of the line. It also fixes#3971.
2. Following on from point 1, the `WC_NONDESTRUCTIVE_TAB` flag could also now be removed. It only ever applied in VT mode, in which case the `TAB` character isn't handled in `WriteCharsLegacy`, so there isn't a need for a non-destructive version.
3. There used to be special case handling for a `BS` character at the beginning of the line when in VT mode, and that is also no longer required. This fixes an edge-case bug which would prevent a glyph being output for code point 8 when `ENABLE_PROCESSED_OUTPUT` was disabled.
4. There was quite a lot of special case handling for control characters in the "end-of-line wrap" implementation, which is no longer required. This fixes a bug which would prevent "low ASCII" characters from wrapping when output at the end of a line.
Then in the `Terminal::_WriteBuffer` implementation, I've simply removed all control character handling, except for `LF`. The Terminal is always in VT mode, so the control characters are always handled by the state machine. The exception for the `LF` character is simply because it doesn't have a proper implementation yet, so it still passes the character through to `_WriteBuffer`. That will get cleaned up eventually, but I thought that could wait for a later PR.
Finally, with the removal of the VT mode handling in `WriteCharsLegacy`, there was no longer a need for the `SCREEN_INFORMATION::InVTMode` method to be publicly accessible. That has now been made private.
## Validation Steps Performed
I've only tested manually, making sure the conhost and Windows Terminal still basically work, and confirming that the above-mentioned bugs are fixed by these changes.
## Summary of the Pull Request
#4354 is a pretty complicated PR. It's got a bunch of conpty changes, but what it also has was some critical improvements to the roundtrip test suite. I'm working on some other bugfixes in the same area currently, and need these tests enhancements in those branches _now_. The rest of #4354 is complex enough that I don't trust it will get merged soon (if ever). However, these fixes _should_ be in regardless.
## PR Checklist
* [x] Taken directly from #4354
* [x] I work here
* [x] Tests added/passed
* [n/a] Requires documentation to be updated
## Detailed Description of the Pull Request / Additional comments
This is four main changes:
* Enable conpty to be fully enabled in unittests. Just setting up a VT renderer isn't enough to trick the host into being in conpty mode - it also needs to have some other flags set.
* Some minor changes to `CommonState` to better configure the common test state for conpty
* Move some of the verify helpers from `ConptyRoundtripTests` into their own helper class, to be shared in multiple tests
* Add a `TerminalBufferTests` class, for testing the Terminal buffer directly (without conpty).
This change is really easier than
would suggest, I promise.
* Remove unneeded c_str() calls when converting an hstring to a wstring_view.
* Remove unneeded c_str() calls when constructing a FontInfo class with a wstring face name.
* Remove unneeded winrt::to_hstring calls when passing a wstring to a method that expects an hstring.
* Remove unneeded c_str() calls when passing an hstring to a method that already accepts hstrings without conversion.
* Remove unneeded c_str() and data() calls when explicitly constructing an hstring from a wstring.

## Detailed Description of the Pull Request / Additional comments
🛑 **STOP** 🛑 - have you read #3495 yet? If you haven't, go do that now.
This PR adds support for three initial sub-commands to the `wt.exe` application:
* `new-tab`: Used to create a new tab.
* `split-pane`: Used to create a new split.
* `focus-tab`: Moves focus to another tab.
These commands are largely POC to prove that the commandlines work. They're not totally finished, but they work well enough. Follow up work items will be filed to track adding support for additional parameters and subcommands
Important scenarios added:
* `wt -d .`: Open a new wt instance in the current working directory #878
* `wt -p <profile name>`: Create a wt instance running the given profile, to unblock #576, #1357, #2339
* `wt ; new-tab ; split-pane -V`: Launch the terminal with multiple tabs, splits, to unblock #756
## Validation Steps Performed
* Ran tests
* Played with it a bunch
This commit introduces a new recursive pane shutdown that will give all
controls under a tab a chance to clean up their state before beign
detached from the UI. It also reorders the call to LastTabClosed() so
that the application does not exit before the final connections are
terminated.
It also teaches TSFInputControl how to shut down to avoid a dramatic
platform bug.
Fixes#4159.
Fixes#4336.

## Summary of the Pull Request
This PR adds two tests:
* First, I started by writing a test where I could write output to the console host and inspect what output came out of conpty. This is the `ConptyOutputTests` in the host unit tests.
* Then I got crazy and thought _"what if I could take that output and dump it straight into the `Terminal`"_? Hence, the `ConptyRoundtripTests` were born, into the TerminalCore unit tests.

Also, some other bits had to be updated:
* The renderer needed to be able to survive without a thread, so I hadded a simple check that it actually had a thread before calling `pThread->NotifyPaint`
* Bits in `CommonState` used `NTSTATUS_FROM_HRESULT` which did _not_ work outside the host project. Since the `NTSTATUS` didn't seem that important, I replaced that with a `HRESULT`
* `CommonState` likes to initialize the console to some _weird_ defaults. I added an optional param to let us just use the defaults.
WT crashes when an unparseable/invalid `backgroundImage` or `icon`
resource path is provided in `profiles.json`. This PR averts the crash
by the validating and correcting resource paths as a part of the
`_ValidateSettings()` function in `CascadiaSettings`.
`_ValidateSettings()` is run on start up and any time `profiles.json` is
changed, so a user can not change a file path and avoid the validation
step.
When a bad `backgroundImage` or `icon` resource path is detected, a
warning screen will be presented.
References #4002, which identified a consistent repro for the crash.
To validate the resource, a `Windows::Foundation::Uri` object is
constructed with the path. The ctor will throw if the resource path is
invalid. Whether or not this validation method is robust enough is a
subject worth review. The correction method for when a bad resource path
is detected is to reset the `std::optional<winrt::hstring>` holding the
file path.
The text in the warning display was cribbed from the text used when an
invalid `colorScheme` is used. Whether or not the case of a bad
background image file path warrants a warning display is a subject worth
review.
Ensured the repro steps in #4002 did not trigger a crash. Additionally,
some potential backdoor paths to a crash were tested:
- Deleting the file of a validated background image file path
- Changing the actual file name of a validated background image file
path
- Replacing the file of a validated background image file path with a
non-image file (of the same name)
- Using a non-image file as a background image
In all the above cases WT does not crash, and instead defaults to the
background color specified in the profile's `colorScheme`. This PR does
not implement this recovery behavior (existing error catching code
does).
Closes#2329
This commit moves the handling of the `BEL`, `BS`, `TAB`, and `CR`
controls characters into the state machine (when in VT mode), instead of
forwarding them on to the default string writer, which would otherwise
have to parse them out all over again.
This doesn't cover all the control characters, but `ESC`, `SUB`, and
`CAN` are already an integral part of the `StateMachine` itself; `NUL`
is filtered out by the `OutputStateMachineEngine`; and `LF`, `FF`, and
`VT` are due to be implemented as part of PR #3271.
Once all of these controls are handled at the state machine level, we
can strip out all the VT-specific code from the `WriteCharsLegacy`
function, which should simplify it considerably. This would also let us
simplify the `Terminal::_WriteBuffer` implementation, and the planned
replacement stream writer for issue #780.
On the conhost side, the implementation is handled as follows:
* The `BS` control is dispatched to the existing `CursorBackward`
method, with a distance of 1.
* The `TAB` control is dispatched to the existing `ForwardTab` method,
with a tab count of 1.
* The `CR` control required a new dispatch method, but the
implementation was a simple call to the new `_CursorMovePosition` method
from PR #3628.
* The `BEL` control also required a new dispatch method, as well as an
additional private API in the `ConGetSet` interface. But that's mostly
boilerplate code - ultimately it just calls the `SendNotifyBeep` method.
On the Windows Terminal side, not all dispatch methods are implemented.
* There is an existing `CursorBackward` implementation, so `BS` works
OK.
* There isn't a `ForwardTab` implementation, but `TAB` isn't currently
required by the conpty protocol.
* I had to implement the `CarriageReturn` dispatch method, but that was
a simple call to `Terminal::SetCursorPosition`.
* The `WarningBell` method I've left unimplemented, because that
functionality wasn't previously supported anyway, and there's an
existing issue for that (#4046).
## Validation Steps Performed
I've added a state machine test to confirm that the updated control
characters are now forwarded to the appropriate dispatch handlers. But
since the actual implementation is mostly relying on existing
functionality, I'm assuming that code is already adequately tested
elsewhere. That said, I have also run various manual tests of my own,
and confirmed that everything still worked as well as before.

## Detailed Description of the Pull Request / Additional comments
I've added a `LineFeed` method to the `ITermDispatch` interface, with an enum parameter specifying the required line feed type (i.e. with carriage return, without carriage return, or dependent on the [`LNM` mode](https://vt100.net/docs/vt510-rm/LNM.html)). The output state machine can then call that method to handle the various line feed control characters (parsed in the `ActionExecute` method), as well the `NEL` and `IND` escape sequences (parsed in the `ActionEscDispatch` method).
The `AdaptDispatch` implementation of `LineFeed` then forwards the call to a new `PrivateLineFeed` method in the `ConGetSet` interface, which simply takes a bool parameter specifying whether a carriage return is required or not. In the case of mode-dependent line feeds, the `AdaptDispatch` implementation determines whether the return is necessary or not, based on the existing _AutoReturnOnNewLine_ setting (which I'm obtaining via another new `PrivateGetLineFeedMode` method).
Ultimately we'll want to support changing the mode via the [`LNM` escape sequence](https://vt100.net/docs/vt510-rm/LNM.html), but there's no urgent need for that now. And using the existing _AutoReturnOnNewLine_ setting as a substitute for the mode gives us backwards compatible behaviour, since that will be true for the Windows shells (which expect a linefeed to also generate a carriage return), and false in a WSL bash shell (which won't want the carriage return by default).
As for the actual `PrivateLineFeed` implementation, that is just a simplified version of how the line feed would previously have been executed in the `WriteCharsLegacy` function. This includes setting the cursor to "On" (with `Cursor::SetIsOn`), potentially clearing the wrap property of the line being left (with `CharRow::SetWrapForced` false), and then setting the new position using `AdjustCursorPosition` with the _fKeepCursorVisible_ parameter set to false.
I'm unsure whether the `SetIsOn` call is really necessary, and I think the way the forced wrap is handled needs a rethink in general, but for now this should at least be compatible with the existing behaviour.
Finally, in order to make this all work in the _Windows Terminal_ app, I also had to add a basic implementation of the `ITermDispatch::LineFeed` method in the `TerminalDispatch` class. There is currently no need to support mode-specific line feeds here, so this simply forwards a `\n` or `\r\n` to the `Execute` method, which is ultimately handled by the `Terminal::_WriteBuffer` implementation.
## Validation Steps Performed
I've added output engine tests which confirm that the various control characters and escape sequences trigger the dispatch method correctly. Then I've added adapter tests which confirm the various dispatch options trigger the `PrivateLineFeed` API correctly. And finally I added some screen buffer tests that check the actual results of the `NEL` and `IND` sequences, which covers both forms of the `PrivateLineFeed` API (i.e. with and without a carriage return).
I've also run the _Test of cursor movements_ in the [Vttest](https://invisible-island.net/vttest/) utility, and confirmed that screens 1, 2, and 5 are now working correctly. The first two depend on `NEL` and `IND` being supported, and screen 5 requires the `VT` control character.

## Detailed Description of the Pull Request / Additional comments
Unittesting for the TerminalApp project has been a horrifying process to try getting everything pieced together just right. Dependencies need to get added to manifests, binplaced correctly, and XAML resources need to get compiled together as well. In addition, using a MUX `Application` (as opposed to the Windows.UI.Xaml `Application`) has led to additional problems.
This was always a horrifying house of cards for us. Turns out, the reason this was so horrible is that the test infrastructure for doing what we're doing _literally didn't exist_ when I started doing all that work last year.
So, with help from the TAEF team, I was able to get rid of our entire house of cards, and use a much simpler project to build and run the tests.
Unfortunately, the latest TAEF release has a minor bug in it's build rules, and only publishes the x86 version of a dll we need from them. But, the rest of this PR works for x86, and I'll bump this when that updated version is available. We should be able to review this even in the state it's in.

## Detailed Description of the Pull Request / Additional comments
My thought pattern here was to minimally disturb the existing code where possible. So where I could, I converted existing functions into coroutine using functions (like in the [core example](https://github.com/microsoft/terminal/issues/3919#issue-536598706)). For ~the most part~ all instances, I used the format where [`this` is accessed safely within a locked scope](https://github.com/microsoft/terminal/issues/3919#issuecomment-564730620). Some function signatures were changed to take objects by value instead of reference, so the coroutines don't crash when the objects are accessed past their original lifetime. The [copy](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1132) and [paste](https://github.com/microsoft/terminal/blob/master/src/cascadia/TerminalApp/TerminalPage.cpp#L1170) event handler entry points were originally set to a high priority; however, the WinRT coroutines don't appear to support a priority scheme so this priority setting was not preserved in the translation.

When user resizes window, snap the size to align with the character grid
(like e.g. putty, mintty and most unix terminals). Properly resolves
arbitrary pane configuration (even with different font sizes and
padding) trying to align each pane as close as possible.
It also fixes terminal minimum size enforcement which was not quite well
handled, especially with multiple panes.
This PR does not however try to keep the terminals aligned at other user
actions (e.g. font change or pane split). That is to be tracked by some
other activity.
Snapping is resolved in the pane tree, recursively, so it (hopefully)
works for any possible layout.
Along the way I had to clean up some things as so to make the resulting
code not so cumbersome:
1. Pane.cpp: Replaced _firstPercent and _secondPercent with single
_desiredSplitPosition to reduce invariants - these had to be kept in
sync so their sum always gives 1 (and were not really a percent). The
desired part refers to fact that since panes are aligned, there is
usually some deviation from that ratio.
2. Pane.cpp: Fixed _GetMinSize() - it was improperly accounting for
split direction
3. TerminalControl: Made dedicated member for padding instead of
reading it from a control itself. This is because the winrt property
functions turned out to be slow and this algorithm needs to access it
many times. I also cached scrollbar width for the same reason.
4. AppHost: Moved window to client size resolution to virtual method,
where IslandWindow and NonClientIslandWindow have their own
implementations (as opposite to pointer casting).
One problem with current implementation is I had to make a long call
chain from the window that requests snapping to the (root) pane that
implements it: IslandWindow -> AppHost's callback -> App ->
TerminalPage -> Tab -> Pane. I don't know if this can be done better.
## Validation Steps Performed
Spam split pane buttons, randomly change font sizes with ctrl+mouse
wheel and drag the window back and forth.
Closes#2834Closes#2277
The first argument to `NotifyTextChanged` incorrectly was `[0,0]`
instead of the length of the text to be removed from the

FYI @DHowett-MSFT (just in case): C++/WinRT uses `winrt::param::hstring`
for string parameters which intelligently borrows strings. As such you
can simply pass a `std::wstring` to most WinRT methods without the need
of having to allocate an intermediate `hstring`. 🙂
## Validation Steps Performed
I followed the reproduction instructions of #3706 and #3745 and ensured
the issue doesn't happen anymore.
Closes#3645Closes#3706Closes#3745
The terminal will use the system setting to determine the number of lines to scroll at a time.
This can be overridden by adding rowsToScroll to app global settings file.
terminal will use the system setting if the app setting is 0, or not specified. No restart is needed to reflect setting changes in system or the settings file.
The default was hardcoded to 4 in the code with a todo comment. 1 works better on precision touchpads, where 4 scrolls too fast.

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

## Summary of the Pull Request
Adds support for `auto` as a potential value for a `splitPane` keybinding's `split` argument. For example:
```json
{ "keys": [ "ctrl+shift+z" ], "command": { "action": "splitPane", "profile": "matrix", "commandline": "cmd.exe", "split":"auto" } },
```
When set to `auto`, Panes will decide which direction to split based on the available space within the terminal. If the pane is wider than it is tall, the pane will introduce a new vertical split (and vice-versa).

These functionalities are included in the search experience.
1. Search in Terminal text buffer.
2. Automatic wrap-around.
3. Search up or down switch by clicking different buttons.
4. Search case sensitively/insensitively by clicking a button. S. Move the search box to the top/bottom by clicking a button.
6. Close by clicking 'X'.
7. Open search by ctrl + F.
When the searchbox is open, the user could still interact with the terminal by clicking the terminal input area.
While I already have the search functionalities, currently there are still some known to-do works and I will keep updating my PR:
1. Optimize the search box UI, this includes:
1) Theme adaptation. The search box background and font color
should change according to the theme,
2) Add background. Currently the elements in search box are all
transparent. However, we need a background.
3) Move button should be highlighted once clicked.
2. Accessibility: search process should be able to performed without mouse. Once the search box is focused, the user should be able to navigate between all interactive elements on the searchbox using keyboard.
<!-- Describe how you validated the behavior. Add automated tests wherever possible, but list manual validation steps taken as well -->
To test:
1. checkout this branch.
2. Build the project.
3. Start Windows Terminal and press Ctrl+F
4. The search box should appear on the top right corner.
This PR fixes the ability to move between already-split panes

Fixes the sides disappearing when entering full screen mode when the window is maximized.
However, now, a Vista-style frame briefly appears when entering/exiting full screen.

## Detailed Description of the Pull Request / Additional comments
When the non-client island window is maximized and has the WS_OVERLAPPEDWINDOW style, SetWindowPos is "lying": the position ends up being offset compared to the one we gave it (found by debugging). So I changed it to use WS_POPUP like the client island window was already doing. But now it has the Vista frame that appears briefly when entering/exiting full screen like the client island window.

Uses the verification in `at` to ensure the index is correct (as @j4james suggests). If `at` throws, then returns false.

## Summary of the Pull Request
An asynchronous event handler capturing raw `this` in `TermControl` was causing an exception to be thrown when a scroll update event occurred after closing the active tab. This PR replaces all non-auto_revoke lambda captures in `TermControl` to capture (and validate) a `winrt::weak_ref` instead of using raw `this`.

## Detailed Description of the Pull Request / Additional comments
`TermControl` is already a WinRT type so no changes were required to enable the `winrt::weak_ref` functionality. There was only one strange change I had to make. In the destructor's helper function `Close`, I had to remove two calls to [`Stop`](https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.dispatchertimer.stop#Windows_UI_Xaml_DispatcherTimer_Stop) which were throwing under [some circumstances](https://github.com/microsoft/terminal/issues/2947#issuecomment-562914135). Fortunately, these calls don't appear to be critical, but definitely a spot to look into when reviewing this PR.
Beyond scrolling, any anomalous crash related to the following functionality while closing a tab or WT may be fixed by this PR:
- Settings updating
- Changing background color

## Validation Steps Performed
Before these changes I was able to consistently repro the issue in #2947. Now, I can no longer repro the issue.
