xonsh v0.5.4 Release Notes

  • ➕ Added:

    • ➕ Add alias xip ("kip") so that xonsh's Python environment (whatever that is) can be modified.
    • HistoryEntry, a SimpleNamespace object that represents a command in history.
    • xonsh.completers.bash_completion module
    • ➕ Added option to report timing information of xonsh startup times. Start xonsh with the --timings flag to use the feature.
    • The Python tab completer will now complete the argument names of functions and other callables.
    • Uptime module added to xonsh.xoreutils. This can report the system boot time and up time.
    • The environment variable XONSH_HISTORY_BACKEND now also supports a value of class type or a History Backend instance.
    • on_envvar_new event that fires after a new envvar is created.
    • on_envvar_change event that fires after an envvar is changed.

    🔄 Changed:

    • history indexing api to be more simple, now returns HistoryEntry.
    • Decoupled bash_completion from xonsh project and added shim back to xonsh.
    • The JSON history backend will now unlock history files that were created prior to the last reboot.

    🛠 Fixed:

    • 🛠 Fixed broken bash completions on Windows if 'Windows Subsystem for Linux' is installed.
    • Readline history would try to read the first element of history prior to actually loading any history. This caused an exception to be raised on Windows at xonsh startup when using pyreadline.
    • 🛠 Fixed issue with readline tab completer overwriting initial prefix in some instances.
    • 🛠 Fixed issue wherein if git or (presumably) hg are aliased, then branch information no longer appears in the $PROMPT
    • 🛠 Fixed an issue with commands that background themselves (such as gpg-connect-agent) not being able to be run from within xonshrc.
