We're not recommend to use this xontrib (see issues section). Use it carefully only if you have very strong muscle memory after hundred of years using Bash or for the education reasons and demonstration how agile is xonsh shell.

Known issues

The xontrib-bashisms appeared in the beginning of xonsh history as part of the default xontribs. It has issues and we recommend to use xontrib-sh instead.

Threading issues

Because of xontrib-bashisms sets THREAD_SUBPROCS=False there are issues around the threading could appear. If you're using bashisms and faced with issues try the same in xonsh --no-rc mode before reporting the issue.

Only interactive mode

The xontrib features are implemented as on_precommand events and these additions do not affect the xonsh language when run as script. That said, you might find them useful if you have strong muscle memory in interactive mode.

Debug

This xontrib may modify user command line input to implement its behavior. To see the modifications as they are applied (in unified diffformat), please set $XONSH_DEBUG to 2 or higher.
