xonsh/xonsh 0.9.23

on GitHub

Added:

• add API docs for ptk_shell.updator module
• add flake8-docstrings to the project. it integrates pydocstyle to flake8.
• Support for ANSI OSC escape sequences in $PROMPT, setting $TITLE for example. (#374, #1403)
• Now ptk_shell supports loading its sections in thread, speeding up the prompt. Enable it by setting $ENABLE_ASYNC_PROMPT=True.
• Added unset, export, set -e, set -x, shopt, complete to xontrib bashisms.
• Use command_cache when finding available commands, to speedup command-not-found suggestions
• Added Visual Studio Code (VSCode) extension and Vim syntax file to the Editors page.
• Added exit(exit_code) function by default in not interactive mode. Now importing exit from sys is not needed.
• Added Python syntax highlighting of xsh files on Github repo xonsh/xonsh
• history clear, history off and history on actions, for managing whether history in the current session is saved.
• ValueErrors from environ.register now report the name of the bad env var
• Add a new color DEFAULT that is used to designate the terminal's default color.
• Add a new special color token RESET used to reset all attributes.
• Add a new xonsh tool 'print_warning' that prints a traceback with a warning message.
• Added xontrib-onepath <https://github.com/anki-code/xontrib-onepath>_ to associate files with apps in xonsh shell like in graphical OS.
• Added print_color and printx functions to builtins as reference to xonsh.tools.print_color.
• Added to xontrib whole_word_jumping: Shift+Delete hotkey to delete whole word.
• Added "Advanced String Literals" to the "Tutorial".
• xonfig jupyter-kernel new subcommand to generate xonsh kernel spec for jupyter.
  Installing a new xonsh kernel for jupyter automatically removes any other one registered with jupyter,
  otherwise the new one might not be used.
• Added xontrib powerline-binding (https://github.com/dyuri/xontrib-powerline-binding) - uses powerline to render the prompt.

Changed:

• Improved printing of xonsh --shell-type argument in help message.
• "Bash to Xonsh Translation Guide" improvements.
• More stable exception handling in the tab completer.
• Changed sections order in docs
• The path type in ${...}.register was renamed to env_path as it should be and added
  new path type instead that represent pathlib.Path. Now you can register typed environment
  variables that will be converted to Path.
• xonsh/environ.py: new rule: for "registered" environment variables (in DEFAULT_VARS or via env.register()),
  if default is set to DefaultNotGiven, then variable has no default and raises KeyError if it is not
  actually defined in environment. Likewise, "var" in __xonsh__.env will return False.
• Changed defaults for ANSICON, TERM and VIRTUAL_ENV to DefaultNotGiven, so code can rationally test whether
  the expected external program has defined these variables. No need to do this for variables that xonsh
  itself defines.
• Moved internal uses of NO_COLOR to RESET.
• When retrieving the git status or other fields for building the prompt xonsh will run
  the git commands with $GIT_OPTIONAL_LOCKS=0. For details on what this entails see
  the git documentation for
  GIT_OPTIONAL_LOCKS <https://git-scm.com/docs/git#Documentation/git.txt-codeGITOPTIONALLOCKScode/>_.
• Minor improvements to the get prompt speed. (Mostly in git.)
• ptk key binding for TAB -- hitting TAB to start completion now automatically selects the first displayed completion (if any).
  hitting TAB when in insert mode inserts TAB, as heretofore. This more exactly follows behavior of readline menu-complete.
  There is no configuration option for tailoring this behavior.
• xonfig info displays whether jupyter detected in environment and
  also path of xonsh jupyter kernel spec, if any.
• xontrib-argcomplete and xontrib-pipeliner description improvement.

Deprecated:

• Deprecated the NO_COLOR color reset token in favor of RESET.

Removed:

• Deprecated --config-path argument suppressed from help.
• setup no longer (tries to) install jupyter kernel automatically,
  user must run xonfig jupyter-kernel manually.

Fixed:

• cygwin needs full path to find exe; disable thread_subprocs as default for cygwin
• Fixed logic in git dirty working directory
• Fixed type registration for *DIRS environment variables.
• Fixed getting typed registered environment variable when it was initialized before registration.
• Fixed #3703 and #3739, recent code change made it impossible to tell whether a (registered) environment variable
  was missing from environment or present and set to its registered default value. The test for ANSICON was
  failing due to this.
• Fixed environment variables substitution: unknown variables stay unreplaced now (#3818).
• Fixed xpg xontrib link
• Fix crash when xonsh tries to run windows app execution aliases.
• Setup wasn't consistently detecting jupyter in environment; python setup.py install worked, but
  pip install . wouldn't (because pip mucks with sys.path),
  nor would install from wheel (because it doesn't run setup.py).
• xonfig info now displays actual value of ON_MSYS and ON_CYGWIN instead of lazy bool type.
  (maybe was happening only on Windows?)
