xonsh v0.6.0 Release Notes

  • ➕ Added:

    • ➕ Added an alias command, matching bash's implementation, available as part of bashisms.
    • New $AUTO_SUGGEST_IN_COMPLETIONS environment variable that enables/disables whether the auto-suggestion result appears in the tab completions.
    • ➕ Added __add__() and __radd__() methods to EnvPath.
    • 👍 Xonsh now supports f-strings, as in Python v3.6+.
    • ➕ Added ipython as unthreadable in command cache threadabilty predictors.
    • Added whole_word_jumping xontrib
    • Added $XONSH_APPEND_NEWLINE environment variable
    • 👌 Support for PEP 515: Underscores in Numeric Literals
    • xonsh.color_tools.make_palette()

    Simple rename of the pre-existing xonsh.color_tools.make_pallete() function.

    • xonsh.tools.decorator() function/method decorator.

    This allows for an API function to be annotated with a decorator that documents deprecation, while also tying in functionality that will warn a user that the function has been deprecated, and, raise an AssertionError if the function has passed its expiry date.

    • 🆕 New xontrib schedule (Xonsh Task Scheduler)

    🔄 Changed:

    • on_pre_prompt is now fired before prompt calculations are made, allowing modifications to the prompt.
    • emacsclient will now return false in the threadable predictors.
    • 👌 Improved the autopair behavior to match that of popular code editors.
    • 📦 Moved the lazy pkg_resources package back to its original place. The will hopefully address some of the slowdown issues experiances on some platforms.
    • When xonsh is used to run an xsh script, the xonshrc is not loaded
    • 🔄 Change in the behavior of the default predictor with binary analysis. The pattern libgpm is use, assuming when gpm is used the program is not threadable. This change solves issues with programs as links.
    • Error messages added to the source command if it is used with a language that is not xonsh or Python.

    🗄 Deprecated:

    • xonsh.color_tools.make_pallette()

    Deprecated in release 0.5.10 and will be removed in release 0.6.0.

    🛠 Fixed:

    • Now f-strings can be used inside @() without explicit enclosing command in ![]
    • 🛠 Fix for x, y, *z = ... unpacking.
    • Git branch detection now correctly passes the environment down to the subprocess call. This allows for branch detection when git is installed into a non-standard location.
    • 📜 Escape regex characters in path_complete to avoid regex parsing errors for certain combinations of characters in path completer
    • 🛠 gistatus: Fixed hash not being shown when in detaced HEAD and there are no tags
    • 🛠 Fix branch colorization when git or hg are aliases.
    • 🛠 Fixed leftover .git/index.lock in gitstatus
    • Made JSON history loading more robust to corrupt files.
    • Starting a new command with an open parentheses will no longer throw a traceback when $UPDATE_COMPLETIONS_ON_KEYPRESS is True.
    • Automatically wrapping subprocess calls would sometimes include semincolons and other line-ending tokens, rather than stopping at them. This has been fixed.

    • 📚 Numerous spelling errors in documentation, docstrings/comments, text strings and local variable names.

    • Spelling error in the xonsh.color_tools.make_pallete() public function declaration. This was fixed by renaming the function to xonsh.color_tools.make_palette() while maintaining a binding of make_pallete() to the new make_palette() in case users are already used to this API.

    • 🛠 Fixed issue with starting triple quote strings being run as a command.

    • 🛠 Fixed a problem with escaping charet () character for cmd.exe in the source-cmd function.

    • EOF in multi-line statement errors were misreported as being on line 0. Now they are correctly reported as being on the last line of the file.
