Windows Terminal Preview v1.15.186

It's Summer in the US, which means that it's really hot there's a new Terminal preview release!

Here's what's in it:

Why are there so many packages? How do I choose?

Features

• Selecting text in the terminal just got better!
  • Use the markMode action to enter mark mode and create a selection at the cursor ( #13053) ( #13358)
    • This is bound to Ctrl+Shift+M by default. Be sure to try it out!
  • Selections made with the keyboard now display a selection marker UI ( #10865)
  • Use the switchSelectionEndpoint action to switch which endpoint you are moving in a selection ( #13370)
  • Use the toggleBlockSelection action to transform your existing selection into a block selection ( #13219)
• [Experimental] We now support scrollbar marks! ( #12948) ( #13163) ( #13291) ( #13414)
  • Use the addMark action to add a scrollbar mark
    • The color optional parameter can be used to specify a color
  • Use the scrollToMark action with a specified direction parameter to scroll between the marks
  • Use the clearMark action to remove a selected mark
  • Use the clearAllMarks action to remove all scrollbar marks
  • The experimental.autoMarkPrompts global setting can be set to true to automatically mark each prompt
    • NOTE: This uses the FTCS_PROMPT sequence from FinalTerm, OSC 133 ; A, which we now support! ( #13163)
  • The experimental.showMarksOnScrollbar global setting can also be set to true to display the marks on your scrollbar
• If you're new to Windows Terminal Preview, but already have Windows Terminal installed and customized, we now migrate your settings over ( #12907) (thanks  @huiyooumich!)
• The tab's context menu now has "Find" as an option ( #13055) (thanks  @Predelnik!)

Changes

• "Open settings file" commands now explicitly mention "JSON" for easier searching ( #13265)
• Color schemes now support "purple" and "magenta" interchangeably in the JSON ( #13261) (thanks  @matthewd673!)
• An accelerator key is now defined for the "Open in Terminal" shell extension ( #13080) (thanks  @ianjoneill!)
• The settings UI's "Save" pane now aligns with the "Open JSON file" footer ( #13282) (thanks  @HO-COOH!)
• The Default Terminal setting in settings UI now has a "Let Windows decide" option ( #13160)
  • An occasional crash while opening the settings UI has been stomped out (same PR!)
• The "Save" and "Discard changes" buttons were reordered in the settings UI to more closely follow the Windows UI guidelines ( #13237)
• @dansmor7 has refined how colored tabs look when they're out of focus or hovered ( #13434) (thanks!)

More Escape Sequences and expanded VT support

Courtesy of  @j4james:

• Applications can now use DECCTR to alter the terminal's color scheme ( #13139) ( #13227)
• The same applications can now use DECAC to assign a color to the default foreground and background colors, as well as change the tab background color ( #13058)
• Other applications can now use DECPS to play a basic sequence of musical notes ( #13208)
  • This feature is preview-only until we can make sure the MIDI sound font is available everywhere Stable ships.

Documentation

• building.md and mouseInput.cpp got cleaned up a bit ( #13333) (thanks  @ofek and  @oferze!)
• We added a Gannt chart to the roadmap ( #13234)

On the back end...

• @lhecker rewrote how we handle coordinates across the project, paving the way for a longer scrollback history and removing a bunch of sources of assertion failures; if you see anything weird that seems like a coordinate system issue, please file it! ( #13025)

Bug Fixes

• We no longer suppress black blackground or gray foreground for PowerShell ( #13352)
  • We have chosen to remove this workaround as newer versions of PowerShell's PSReadline component contain a fix for the issue.
  • This was a compatibility band-aid that was impacting the capabilities of great projects such as  Oh My Posh.
  • If you see unexpected black backgrounds appearing behind text while typing a command in PowerShell, make sure your PSReadline version is up to date. You can update your version of PSReadline by running the command, Update-Module PSReadline.
• The Default Terminal banner is now hidden if you opened a session via default terminal ( #13344)
  • AKA: We won't nag you to set Terminal as your default if it's demonstrably the default ;P
• [O is no longer output erroneously from focus events for clients of libuv like neovim ( #13260)
• AtlasEngine no longer secretly increases the font size of HTML/RTF copies when the font changes ( #13384)
• Keyboard selection is now limited to the scrollable area ( #13318)
• The "Open in Terminal" shell extension is now hidden when accessing a non-filesystem path like "Quick Actions" ( #13206) (thanks  @leejy12!)
• Clearing the screen via cls or Clear-Host won't leave behind an erroneous line of text ( #13324) (thanks  @j4james!)
• Default Terminal sessions now properly pass focus events when opened ( #13247)
• Terminal will now use Unicode 14.0 to determine the width of some Unicode characters ( #13292)
• We will no longer try to launch wsl to ask it to tell us about distributions when it's obvious that you don't have any ( #13436)
• We've fixed a minor race condition in default terminal handoff that impacted nobody ( #13410)

Reliability

• We no longer crash when a screen reader is reading from a CLI app using the alt buffer ( #13250) ( #13244)
• Deleting the last profile in the settings UI no longer causes a crash ( #13242)
• Opening Windows Terminal via the Win+X menu no longer occasionally crashes ( #13212)
• SetConsoleWindowInfo can no longer crash a terminal tab ( #13212)
