Windows Terminal Preview v1.17.1023

[DHowett]

Happy New Year! Unwrap the first Preview build of Terminal in 2023, and find inside . . .
a bunch of cool stuff! Our community really proverbially killed it last year, so we're proud to get their work (and ours, of course) out to the world.

Note From this version forward, we are dropping some of the more clutter-y parts of our version number in our git tag and about dialog.
For deployment purposes, however, the packages will retain all four version components. The package versions for this release are 1.17.10234.0 and 1.17.10235.0.

Features

• You can now customize the order and contents of the New Tab menu (New Tab Menu Customization #13763) (thanks @FWest98!) (Fix a crash on startup with a folder entry without entries #14629)
  • Right now, you can only do this with JSON; check out the docs for newTabMenu
  • The first time you save your settings in 1.17, we'll convert your existing menu to the new format. This is
    lossless.
  • This feature includes support for adding folders, separators, and profiles that meet certain criteria in addition
    to the standard/built-in default menu layout.
• You can now set the scroll bar to be "always" displayed (thanks @sotteson1!) (Add support for scroll bar 'always' setting #14047)
  • JSON field $profile.scrollbarState has learned the new enum value always.
• After a process terminates, you can press Ctrl+D to close its pane or Enter to relaunch it (When the terminal has exited, ctrl+D to close pane, Enter to restart terminal #14060)
• Terminal now supports the remaining FinalTerm mark types (command input start, command executed and command finished) (Implement the rest of the FTCS marks #14341)

Themes

• Terminal now supports using Mica as a background material on Windows 11 (Re-add support for Mica, transparent titlebars #13935) (Only use Mica in the SUI if Mica is available #14675) (Use mica in the SUI if mica is enabled in the theme #14567) (Fix a crash when the theme doesn't have a window #14540) (Use ThemeLookup for the SUI bg too #14644) (Update the titlebar visibility when we gain/lose focus too #14708)

  • Note As a reminder, theme settings are only available via JSON.

  • To use Mica, set up a new theme with the following settings:
    • {"window": {"useMica": true}, "tabRow": {"background": "#00000000"}}
• You can now configure a color scheme (per profile) to apply in System Light theme and System Dark theme (Add support for switching the scheme based on the app's theme #14064) (thanks @bennettnicholas!)
  • Set $profile.colorScheme to an object containing the keys light and dark, ala { "light": "Scheme One", "dark": "Scheme Two" }.
  • When first implemented, this may have crashed; it no longer does so! (Check for null lParam in WM_SETTINGSCHANGE #14653) (thanks @jboelter!)
• Likewise, you can do the same thing for the application theme (Enable switching app theme based off of OS theme #14497)

Changes

Fundamentals

• The backing buffer now stores surrogate pairs inline, and measures columns differently (Rewrite ROW to be Unicode capable #13626) with bug fixes from @j4james (thanks!) (Prevent horizontally scrolling wide chars erasing themselves #14650)
  • Please report any unusual behavior regarding Unicode characters, including selection, copy, paste and display.
• The contents of the Terminal package are now code-signed, so those of you who deploy it unzipped will no longer
  get in trouble with your IT folks (Code sign the contents of the Terminal package #14710)

UI

• We have changed how we display our version numbers, opting to hide "bookkeeping" information such as the final
  digit of the version number. Those numbers will still be noted in the package release notes and are still germane to
  deployment scenarios. (Remove the win10/win11 digit from our version number.  #14660)
• You can now configure all of the launch position parameters in the Startup section of the Settings UI ([SUI] Polish Launch Parameters setting controls #14569) (Fix setting launch position in the Settings UI not working #14518) (Fix some issues with the launch parameters in the SUI #14186) (Update LaunchPosition to use int32_t instead of int64_t #14190) (Implement InitialPosition and CenterOnLaunch in the SUI #13605) plus community bug fixes (Ensure X/Y controls are updated when default launch pos selected #14522) (thanks @ianjoneill!)
• We've revamped the color schemes page for ease of understanding and sheer coolness (Improve the color schemes page in the SUI #14470) (Fix the selected color scheme list item container background being blue in Windows 10 #14706) (Automatically focus the ColorSchemeListView when we navigate to the ColorSchemes page #14631) (Fix use of tabs instead of spaces in ColorSchemesPageViewModel.idl #14550) (Manually set the automation name of the default color scheme for screen reader #14704)
• When configuring a profile's color scheme, you will now see a tiny preview of that color scheme before you
  select it (Add color chips to the color scheme dropdown in Appearance #14587) (Update Profile and Appearance VMs to use CSVM; remove nav state #14572)

Usability

• wt now supports the --pos and --size commandline arguments to control the position and size of the new
  window (Add --pos and --size cmdline args #13730) (thanks @ianjoneill!)
• When you duplicate a tab, the new will open next to the current tab (Duplicated tabs open next to the current tab #14521) (thanks @vamsiikrishnaak!)
• You can now use exe and dll resources for icon paths, as in C:\Windows\system32\shell32.dll,41 (Allow for exe/dll paths for the Icon setting #14107)
  • However, it looks like we have an off-by-one error (that should be 42 above, but whoops. We'll fix that.)
• The context menu now has tooltips (Add tooltips to context menus #14058)

This discussion was created from the release Windows Terminal Preview v1.17.1023.

[Crachlow]

Is it possible to make support for copying the selected text to the clipboard, as in cmd, with the Enter key, and not Ctr C? It's much more convenient.

[zadjii-msft]

Sure is!

        { "command": { "action": "copy", "singleLine": false }, "keys": "enter" },

Should already be in the default settings 😉

Sorry. I must have been using the old one. Now updated. Everything is good.
