* move the render thread init up; gets rid of verifier stops
* s/INVALID_HANDLE_VALUE/NULL/g since CreateEvent() and CreateThread() return a NULL HANDLE on failure; resolves another cause of AppVerifier breaks
* Support OSC to set default background and foreground colors
* Update the Terminal theme when the background changes
* Fix whitespace per code-review
* Add Documentation Comments
Also fix a few outdated comments and whitespace
* Update Telemetry codes per code review
* Add Unit Tests for OSC ForegroundColor and BackgroundColor
* Add a couple additional test cases
* Minor doc and whitespace change per PR review
* Update comment help per code review
* Add another OSC 10 & 11 test case, improve output
* Comments and syntax cleanup per code reviews
* added another method to scroll with keyboard
* set lastscrolloffset to 0
* fixed unused variable
* renamed ViewPort to Viewport
* changed keyBoard to keyboard in the functions, and added expliantion for function
* set identifying environment variable for new connections
Set a new 'WT_SESSION' environment variable when creating new terminal
connections to allow shells to detect a unique Windows Terminal session.
The value of the variable is a stringified GUID as returned by
CoCreateGuid.
How verified:
- "razzle" & vs debug build
- runut
- manual inspection
* * use winrt::guid type for connection guid
* use Utils::GuidToString for guid stringification
* expose guid parameter in ITerminalConnection idl
* - poke guid through ITerminalConnection
- misc. review fixes
- throw if CreateConPty fails in ConhostConnection::Start
- apply [[nodiscard]] and noexcept in various places
* - simplify environment variable extraction in UpdateEnvironmentMapW
* - use Utils::CreateGuid instead of CoCreateGuid in ConHostConnection()
* Added focus tracking to TermControl to prevent clicks which refocus the terminal window from selecting text.
* Moved open brace to a new line per repo code style.
* Moved the TermControl's _MouseClickHandler's focus check into the Mouse specific block of code. This lets any touch and drag events scroll the terminal's contents.
Fixes#670.
* fix for historySize=32767 hang (except for historySize=0 case); tests still in progress
* tests run and almost pass - failure is a real bug in my change
* fixed bug that caused tests to fail, but it seems another bug causes the app to crash with a zero row count
* fix the additional bug (at a higher layer) mentioned in previous commit description
* Fix chk build assertion failures in new tests
It seems C++/WinRT doesn't like it when you implement a Windows Runtime
interface but then create instances of the implementing class
with function-call lifetime (aka stack allocation). That makes sense
given that WinRT objects are COM objects, but in my defense I was following
this example where they are just fine instantiating the `App` object
on the stack:
https://docs.microsoft.com/en-us/windows/uwp/cpp-and-winrt-apis/author-apis#if-youre-not-authoring-a-runtime-class
* tabs to spaces
* CR feedback
* fix minor CR feedback (incorrect test log message)
* added keybindings
* untabfied the files
* fixed spacing issues and renamed termheight
* changed function names and other improvements
* made some auto variables const auto
* fixed tabs
* another try for the broken spacing
This encompasses a handful of problems with column counting.
The Terminal project didn't set a fallback column counter. Oops. I've fixed this to use the `DxEngine` as the fallback.
The `DxEngine` didn't implement its fallback method. Oops. I've fixed this to use the `CustomTextLayout` to figure out the advances based on the same font and fallback pattern as the real final layout, just without "rounding" it into cells yet.
- `CustomTextLayout` has been updated to move the advance-correction into a separate phase from glyph shaping. Previously, we corrected the advances to nice round cell counts during shaping, which is fine for drawing, but hard for column count analysis.
- Now that there are separate phases, an `Analyze` method was added to the `CustomTextLayout` which just performs the text analysis steps and the glyph shaping, but no advance correction to column boundaries nor actual drawing.
I've taken the caching code that I was working on to improve chafa, and I've brought it into this. Now that we're doing a lot of fallback and heavy lifting in terms of analysis via the layout, we should cache the results until the font changes.
I've adjusted how column counting is done overall. It's always been in these phases:
1. We used a quick-lookup of ranges of characters we knew to rapidly decide `Narrow`, `Wide` or `Invalid` (a.k.a. "I dunno")
2. If it was `Invalid`, we consulted a table based off of the Unicode standard that has either `Narrow`, `Wide`, or `Ambiguous` as a result.
3. If it's still `Ambiguous`, we consult a render engine fallback (usually GDI or now DX) to see how many columns it would take.
4. If we still don't know, then it's `Wide` to be safe.
- I've added an additional flow here. The quick-lookup can now return `Ambiguous` off the bat for some glyph characters in the x2000-x3000 range that used to just be simple shapes but have been retroactively recategorized as emoji and are frequently now using full width color glyphs.
- This new state causes the lookup to go immediately to the render engine if it is available instead of consulting the Unicode standard table first because the half/fullwidth table doesn't appear to have been updated for this nuance to reclass these characters as ambiguous, but we'd like to keep that table as a "generated from the spec" sort of table and keep our exceptions in the "quick lookup" function.
I have confirmed the following things "just work" now:
- The windows logo flag from the demo. (⚫⚪💖✅🌌😊)
- The dotted chart on the side of crossterm demo (•)
- The powerline characters that make arrows with the Consolas patched font (██)
- An accented é
- The warning and checkmark symbols appearing same size as the X. (✔⚠🔥)
