0.19.5 (2025-06-24)

Features

• #5745 - send Ctrl+C event on Windows instead of forceful terminate (#5838) (ac02ea1)
• completion: Accept single completion in VI MODE using Ctrl+] (#5763) (45c6436)
• New experimental Rust based parser for xonsh (#5749) (cff9046)

Bug Fixes

• don't skip history items when running full history pull after session-specific pull (#5826) (5ecdcae)

Performance Improvements

• Disable double check is_file on Windows systems to speedup IO (b112b83)

Documentation

• Add missing bash conversion example (#5832) (1985128)

Changed:

• Updated bash_completion.py from archived xonsh/py-bash-completion repo. The last update fixes empty completion list issue.

Authors:

• Gil Forsyth
• anki-code

Changed:

• On Windows, cmd.exe-based aliases now resolve to %SystemRoot%\System32\cmd.exe by default (and fallback to COMSPEC only if the former cannot be found).

Fixed:

• Using trace on with .xsh scripts could previously lead to
  a spurious ignored exception showing up on stderr. This is now fixed.
• pipelines: fixed 'NoneType' object has no attribute 'pid' exception (#5794).

Security:

• The history delete action on the sqlite backend used to
  pass matched history lines to a SQL statement without sanitization.
  This could lead to unexpected SQL being run on the history database.
  This is now fixed. Security risk: low.

Added:

• env: add $XONSH_PROMPT_CURSOR_SHAPE for configuring prompt cursor shape.
• env: Added $XONSH_CONFIG_DIR, $XONSH_DATA_DIR and $XONSH_CACHE_DIR.
• SIGHUP will now be forwarded to child processes when received by the main xonsh process.
  This matches the behavior of other shells e.g. bash.
• Documented the fact that the on_postcommand event only fires in interactive mode.
• history: Added and documented --session-id parameter for history pull command.
• history-json: Implemented history pull for JSON history backend.

Fixed:

• Running a subcommand in an event handler will no longer block xonsh from exiting.
• history: Prevented history pull command from adding consecutive duplicates to propmter history.
• prompt toolkit: Fixed autosuggest sometimes not updating when up-arrow is pressed (#5787).
• Subprocess-based completions like
  xontrib-fish-completer <https://github.com/xonsh/xontrib-fish-completer>_
  no longer append a space if the single available completion ends with
  a directory separator. This is consistent with the behavior of the
  default completer.
