xonsh/xonsh 0.10.0

on GitHub

A HUGE release with tons of new stuff! 🥳 🎉

Notably the completion system was completely rewritten making it much more robust and flexible!
Also ctrl-Z should work by default and interactive commands won't be threaded.

Due to an issue with the new pip resolver, please install with --use-deprecated=legacy-resolver.

Note that the AppImage python version was upgraded to 3.9

Added:

• Added ability to set XONSH_HISTORY_FILE before loading the history backend.

• Added ability to get the arguments list in ExecAlias using $args and $arg<n> environment variables.

• Added instruction how to run xonsh AppImage on Alpine

• Xonsh now supports generators as completer functions.

• Completion Context - Allow completers to access a parsed representation of the current commandline context.

• Added casting CommandPipeline to int, hash and str.

• Ability to call the tool by the name from callable alias with the same name without the infinite loop error.

• on wsl field when running xonfig (when linux is detected)

• Help and superhelp (obj? and obj??) now use the __name__ if available.

• added $XONSH_GITSTATUS_FIELDS_TO_HIDE to hide unwanted fields from {gitstatus} prompt field.

• Added number of lines added and removed to gitstatus

• Saving current working directory (cwd) to the history.

• Added XONSH_HISTORY_SAVE_CWD environment variable.

• Added environment variable $COMPLETE_DOTS to specify how current and previous directories should be tab completed in cd ('./', '../'):

  • always Always complete paths with ./ and ../
  • never Never complete paths with ./ and ../
  • matching Complete if path starts with . or ..

• Complete import keyword in from ... import statements.

• Enabled case-insensitive completions for the jedi xontrib.

• Non-exclusive completers that enable aggregating multiple completer results.

• New $XONSH_CAPTURE_ALWAYS variable for opt-in interactive capturing.
  Since this capturing breaks background jobs and some interactive programs (like git invoking an editor),
  This behavior is now opt-in using this variable.
  See #4283 and linked issues.

• Wrap selection with quote/parens when $XONSH_AUTOPAIR=True.

• Now xonsh will work with Python 3.10. (Match statement is not supported).

• In addition to reading single rc files at startup (/etc/xonshrc, ~/.config/xonsh/rc.xsh),
  xonsh now also supports rc.d-style config directories, from which all files are sourced. This is
  designed to support drop-in style configuration where you could, for example, have a common config
  file shared across multiple machines and a separate machine specific file.

  This is controlled by the environment variable XONSHRC_DIR, which defaults to
  ["/etc/xonsh/rc.d", "~/.config/xonsh/rc.d"]. If those directories exist, then any xsh files
  contained within are sorted and then sourced.

• Added xontrib-prompt-starship - Starship prompt in xonsh shell.

• Added XONSH_SUBPROC_CAPTURED_PRINT_STDERR (default False) environment variable to hide unwanted printing the stderr when using captured object.

• A $XONSH_TRACE_COMPLETIONS variable for completions debugging.

• Added warning about prompt-toolkit in the welcome message.

• Added history backend name to the xonfig.

• xontrib-linuxbrew <https://github.com/eugenesvk/xontrib-linuxbrew>_ to add Homebrew's shell environment to xonsh shell on Linux

• Added xontrib-macro-lib - the library of the useful macros for the xonsh shell: https://github.com/anki-code/xontrib-macro-lib

Changed:

• update imphooks encoding regex to match the newer version at PEP 263
• Enabled bracketed paste mode for readline to protect against paste jacking
• The group of environment variables around history moved to the "Interactive Prompt History" section.
• Disabled completing subpaths for commands in jedi.
• Improved which output for non-simple aliases
• New json history will be in XONSH_DATA_DIR/history_json directory.
• Completers for and/or, &&/||/| and environment variables are now non-exclusive.
• Disabled ptk copying words/lines to clipboard on deletion (can be re-enabled with $XONSH_COPY_ON_DELETE).
• Separated between XONSH_DEBUG and XONSH_NO_AMALGAMATE. Setting XONSH_DEBUG=1 now acts like XONSH_DEBUG=2 before (basic information like input transformation, command replacement) and XONSH_DEBUG=2 like XONSH_DEBUG=1 before (more debugging information presented, like PLY parsing messages).
• Cleaned up available aliases for shell_type
• Speedup commands-cache by saving results between runs and use the last run's result
• The completer add command after the non-exclusive completers.
  This means it will not block them from adding their completions.
• Updated the tab-completion tutorial.

Fixed:

• handle importing/decoding user modules with a 'UTF-8 with BOM' encoding (#4160)
• Fixed XONSH_HISTORY_FILE that has the actual path from the history backend now
• Annotated assignments (x: int = 42, x: int).
• Fixed xpip sudo behavior in xonsh AppImage.
• Prevent cancelled future errors for async prompt ($ENABLE_ASYNC_PROMPT) fields from bubbling up (and destroying the prompt's formatting)
• $() no longer silently captures stderr
• Added catching callable argument and raising appropriate exception
• Crashing command-not-found output for bad file names on linux.
• Fixed error message when an empty command is run
• Fixed @$ crash when no output is sent out by the command
• Fixed xonsh crash when launched using xonsh -c '$("")'
• now abbrevs callback will not remove word from buffer.text. See #3642 (comment)
• Fixed the incorrect SyntaxError that was thrown when a subprocess command was preceded by a comment ending with a colon
• Fixed the missing auto-indentation in readline and prompt_toolkit when a statement ending with a colon was followed by a comment
• Fixed the incorrect auto-indentation in prompt_toolkit when a comment ended with a colon
• Fixed JSON history garbage collection for XONSH_HISTORY_SIZE in seconds.
• Fixed skip completer (completes sudo, which and other commands).
• In a subprocess command, having whitespace in between the left bracket and the command no longer raises a SyntaxError.
• Reduced history reading when run script or command. Potential speed increasing.
• Fixed crash on statup if XONSH_COLOR_STYLE is set to something invalid.
• Fixed the colorize and/or keywords.
• Functions can be used for $TITLE, the same way as for $PROMPT. (#4148)
• wsl detection works on archlinux wsl2 now (and hopefully everywhere)
• Fixed an exception when run xonfig wizard in no RC mode.
• Bash completions now handle quoted and space-containing arguments better.
• import completions always work.
• Test consistent RC loading behaviour in a variety of startup scenarios
• Absolute paths to executables don't break bash completions anymore
• Fix colors and text in the welcome message.
