- Adds a way to view help on alternate screen buffer for full help and uses a Pager from `Microsoft.PowerShell.Pager`.
- Implements dynamic help for parameters by showing it below the current command line like `MenuComplete`.
1. Fix menu completion to work with the predictive list view (fix#1935 -- regression introduced in 2.2.0-beta1)
2. Fix menu completion to clear lines properly when the menu top changes on re-drawing (regression introduced in 2.2.0-beta1)
3. Fix how `RightArrow`, `LeftArrow`, `UpArrow`, and `DownArrow` navigate in the menu view (enhancement)
* Use LenthInBufferCells for Completions
* Remove unused ShortenLongCompletions
Use LengthInBufferCells() for determining the display width of menu items
in CreateCompletionMenu() to correct support of CJK characters in
completion items.
- Prevent adjustment of `userCompletionText` in `FindUserCompletionTextPosition` when the match contains `{` in CompletionText[1] if the `userCompletionText` is not longer than 1 char
- Preserve the splat sigil at start of completions of type `Variable`.
Adjusting `userCompletionText` blindly led to `ArgumentOutOfRangeException` on incorrectly braced splats on input `@?`.
Loss of the sigil of splats led to the splat sigil always being marked as replaced, and in situations where the PowerShell completion logic returned incorrect completions of splats with braces, led to a `ArgumentOutOfRangeException`.
There are likely issues introduced by this PR,
but I'm merging for a new Beta so this code gets more testing.
* Introduce PSKeyInfo type alias
* Explicit conversions b/w ConsoleKeyInfo and PSKeyInfo
* Change tests to use actual ConsoleKeyInfo data
* Add fr-FR keyboard layout tests
* Add KeyInfo-ru-RU-windows.json (#839)
All impossible without Shift shortcuts labeled as "Investigate: true"
Alt+Spacebar tracked by windows itself
* Add KeyInfo for Polish (Programmers) layout on Windows and Linux (#870)
On Windows *Alt+Spacebar* is hijacked by Windows
On Linux any *Alt+F1-12* combination was not detected
LanguagePrimitives.TryConvertTo raises (and catches) exceptions on
failed convertions to an enum type like ConsoleColor.
These exceptions were affecting debugging performance of the menu and we
never want exceptions if it's easy to avoid, which in this case it is.
A recent PR disabled the display of tooltips, and there were
some problems with the menu display when the command line
was at the bottom of the buffer and scrolling was necessary.
Fix#763 and probably #765
If the console buffer is small, we sometimes tried to move the cursor outside the buffer when displaying possible completions or the completion menu.
The fix:
* avoids displaying the tooltip if it doesn't fit in the buffer
* places the cursor without scrolling when simply printing the completions (no menu selection)
Write-Progress or some other UI might scroll the screen while computing completions and that needs to be detected to properly render after fetching the completions.
Introduced a very minimal terminal emulator, enough to support the
colors used by default (ConsoleColor).
There could be some more error checking or just somehow ignoring unknown
escapes, but we'll see if this is sufficient for now.
Fix#596
Rewrote the custom key binding code to be more portable.
Some runtime checks are necessary because of impossible to reconcile
differences.
Some Win32 P/Invoke calls are still needed due to lack of information in
the ConsoleKeyInfo.
Some keys are currently not available on Linux due to a CLR bug, others
aren't available ever because terminals don't unique character sequences
for a given key press that might differ in just the Shift or Ctrl state.
