vtm

Changes (release for testing window rendering in GUI mode, win32 only)

• This is still only a test GUI window.
• Add support for glyph run alignment, rotation and flipping (using Unicode Variation Selectors VS4-VS14). See #571 for details.
• Update to Unicode 16.0 ("Large Type Pieces" support).
• Add support for GUI full screen mode.
• Add a GUI related config section:

  <config>
    <gui> <!-- GUI related settings. (win32 platform only for now) -->
        <antialiasing = off />   <!-- Antialiasing of rendered glyphs. Note: Multi-layered color glyphs such as emoji are always antialiased. -->
        <cellheight = 20 />      <!-- Text cell height in physical pixels. Note: The width of the text cell depends on the primary font (the first one in the font list). -->
        <gridsize = 0,0 />       <!-- Window initial grid size in text cells. -->
        <wincoor = 0,0 />        <!-- Window initial coordinates (top-left corner on the desktop in physical pixels). -->
        <winstate = undefined /> <!-- Window initial state: undefined | maximized | minimized -->
        <fontlist> <!-- Font fallback list (LF-delimited (\n), ordered). The rest of the fonts available in the system will be loaded dynamically. -->
            "Courier New\n" <!-- Primary font. Its metrics define the cell geometry. -->
            "Iosevka Term\n"
            "JetBrains Mono\n"
            "Cascadia Mono\n"
            "DejaVu Sans Mono\n"
            "Envy Code R\n"
            "Fira Code\n"
            "monofur for Powerline\n"
            "Lucida Console\n"
            "Consolas\n"
            "Anonymous Pro\n"
            "Source Code Pro\n"
            "NSimSun\n"
            "Noto Sans Devanagari\n"
        </fontlist>
        <testtext="test \e[41;94m UTF-8 \e[m string 👌︌︉︅󐀮😃👌︋︅󐀮 (See ~/.config/vtm/settings.xml: /config/gui/testtext/)"/>
    </gui>

Changes

• Fix wide taskbar menu layout (config/menu/wide=on). https://github.com/directvt/vtm/issues/584#issuecomment-2068393457
  

Changes:

• Revise title/footer rendering in GUI mode (fix shadows and overbright). #571
• Add a side border option config/term/layout/border (=0 by default). #584:

<config>
    <term>
        <layout>
            <oversize=0 opacity=0xC0/>  <!-- Scrollback horizontal (left and right) oversize. (for convenient horizontal scrolling). -->
            <border=1/>                 <!-- Viewport's left and right border. -->
        </layout>
    </term>
</config>

• config/term/fields section renamed to config/term/layout
• config/term/fields/size option renamed to the config/term/layout/oversize section
• config/term/fields/lucent option renamed to config/term/layout/oversize/opacity

Changes

• Switch to ARGB pixel format (0xaarrggbb) from ABGR. All color settings in your current configurations are affected - the red channel has been swapped with the blue channel. This had to be done for compatibility with GUI mode.
• Terminal: Fix viewport reset when changing selection mode. #584
• Introducing a graphical window that can run on various Windows platforms starting with Windows 8.1 (including Window Server 2019 Core). #571
  • vtm automatically switches to the graphical mode if it is launched by the graphical shell (explorer.exe), or by the start vtm.exe command (e.g. on Windows Core).
  • Text cell rendering is not implemented. It is just a proof of concept.
  • The vtm server starts in the background, despite the fact that its interface is not rendered yet.
  • It is not yet clear whether we need to involve the GPU here for rendering. It's not a big deal, but at the moment it seems that software rendering is quite enough (60fps, etc). Over time it will become clear.
  • Colored emojis are funny on Windows8:
    
  • On Windows Server Core (which is desktopless), the system window manager doesn't support "overbright" pixels (it requires alpha-premultiplied pixel values), so translucent windows are a little buggy, but that's not a big deal:
    
  • Windows PE is also supported:
    

Changes

• Fix PowerShell/PSReadLine input echo on Windows. #581
  

Changes

• Add color cursor support (OSC 12/112):
  Set/reset cursor color:

  printf "\e]12;rgb:00/ff/00\e\\"  # Set cursor color to green.
  printf "\e]112;\e\\"             # Reset cursor color to default.
  

  Run terminal with red cursor:

  printf "vtm.run(id=Term cfg='<config><term><cursor><color bgc=reddk/></cursor></term></config>')" | vtm
  

  Set red cursor in settings.xml:

  <config>
    <term>
      <cursor>
        <style="block"/> <!-- Cursor style: underline | block -->
        <blink=400ms/>       <!-- Cursor blink period. Set to zero for a steady cursor. -->
        <show=true/>
        <color bgc=reddk fgc=default /> <!-- Cursor cell color. By default, the cursor color (bgc) is set to either black or white depending on the lightness of the underlying text background. -->
      </cursor>
    </term>
  </config>
  

• Make the terminal window opaque by default.
• Make window shadow configurable:

  <config>
    <appearance>
      <defaults>
        <shadow> <!-- Window shadow configuration. -->
          <enabled = true />
          <blur = 3 />         <!-- Blur radius (in cells). Default is 3. -->
          <bias = 0.37 />      <!-- Shadow contour bias [0.0 - 1.0]. Default is 0.37 -->
          <opacity = 105.5 />  <!-- Opacity level (alpha) [0.0 - 255.0]. Default is 105.5 -->
          <offset = 2,1 />     <!-- 2D offset relative to the window (in cells). Default is 2,1. -->
        </shadow>
      </defaults>
    </appearance>
  </config>
  

v0.9.75b

Changes

• Make terminal scrollback transparent by default to provide clear boundaries for the console applications output:

  <config>
    <term>
      <color>
        <bground = transparent />  <!-- Independent background color of the scrollback canvas. Set to 0x00ffffff(default) to sync with SGR49 (default background). -->
      </color>
    </term>
  </config>
  

Changes

• Add window shadows:
  
• Make the terminal scrollback background color independent and configurable:

  <config>
    <term>
      <color>
        <bground = transparent />  <!-- Independent background color of the scrollback canvas. Set to 0x00ffffff(default) to sync with SGR49 (default background). -->
      </color>
    </term>
  </config>
  

  
• Remove taskbar menu item's attributes: bgc=..., fgc=..., slimmenu=... (use cfg=... attribute instead).

  echo "vtm.set(id=Azure label='Azure Terminal' type=dtvt cmd='vtm -r term' cfg='<config><term><color><default fgc=0xFFffff00 bgc=bluedk/></color></term></config>')" | vtm
  

• Add support for styled and colored underlining (SGR-4:*, SGR-58/59).
• Fix bug with CSI subparameters parsing.
  repro:

  printf "\e[48:2::255:255:255mWhite\e[m\n"
  printf "\e[48:2:255:255:255mWhite\e[m\n"
  

Changes

• Fix semantic block selection

Changes

• Fix standalone terminal focus, #575
• Render colored whitespaces instead of shaded block glyphs "▓▒░".
• Add support for selecting semantically (OSC 133) homogeneous blocks with the mouse (4x left-click).
• Add semantic markers for cmd.exe by default (OSC 133).
• Built-in terminal/teletype: Change the multiple left click behavior:
  • Double left click: Select a word.
  • Triple left click: Select paragraph.
  • Quadruple left click: Select the entire scrollback buffer or semantic block (when using OSC 133).
  • Quintuple left click: Select the entire scrollback buffer.

Changes (Windows only)

• Fix cli usage output for non-UTF-8 code pages, #572

Changes (Windows only)

• Fix dead keys in cmd.exe for US-International kb layout, #586

Changes (Windows only)

• Fix dead keys in cmd.exe for French AZERTY kb kayout, #568

Changes (Windows only)

• Enable OSC 9;9 notifications for cmd.exe by default:
  If PROMPT envvar is empty or equals "$P$G", set it to:

  PROMPT="$e]9;9;$P$e\$P$G"
  

Changes

• Make the CWD sync command template configurable via settings:

  <config>
    <term>
    	<cwdsync=" cd $P\n"/>
    </term>
  </config>
  

  Now it is possible to configure the cwdsync command template, for example, make it without prefixed whitespace to be compatible with Far Manager (https://github.com/FarGroup/FarManager/issues/798):
  pwsh:

  echo "vtm.run(id=Term cfg='<config><term cwdsync=`"cd `$P\n`"/></config>')" | vtm
  

https://github.com/FarGroup/FarManager/assets/11535558/7070f3ce-9603-48ca-b237-dbfe188ea7ae

Changes

• Fix window focusing when left clicking in the window menu.
• Prefix the cd command with a space to avoid command history when synching cwd.
• Don't save space prefixed commands in cmd.exe history.
• Log OSC9;9 notifications.

Changes

• Force the cmd.exe's cd to always change the drive:

  C:\Temp> cd d:\temp
  d:\temp> _
  

Changes

• Fix vtty applet defaults, #562
• Add experimental synchronization of the current working directory for all terminal windows with the "Sync" switch enabled.
  Shell CWD Sync activation (OSC9;9):
  • Windows Command Prompt:

  PROMPT $e]9;9;$P$e\$P$G
  

  • PowerShell:

  function prompt{ $e=[char]27; "$e]9;9;$(Convert-Path $pwd)$e\PS $pwd$('>' * ($nestedPromptLevel + 1)) " }
  

  • Bash:

  export PS1='\[\033]9;9;\w\033\\\]${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
