Suggestion: xonsh support

[anki-code]

Hey! Thank you for this! It will be cool to have https://xon.sh support.

Looks good! I'll see about adding support on the 29th, but more likely when I get back from holiday on the week of the 16th.

for anyone wanting to tackle this, I have a rudimentary guide/checklist at:

I've landed initial xonsh support in dorothy, with these interactive.zsh caveats that someone more xonsh savvy can figure out:

• the interactive.xsh config file won't load:

  • dorothy/sources/interactive.xsh

    Line 7 in a613644

    # load_dorothy_config('interactive.xsh') # <-- this isn't availiable for some reason

• ssh not yet implemented, inspiration can be:
  • https://github.com/dyuri/xontrib-ssh-agent/blob/master/xontrib/ssh_agent.xsh
  • https://github.com/theRealBithive/xontrib-init-ssh-agent/blob/main/xontrib/init_ssh_agent.py
• autocomplete not yet implemented
• history not yet implemented
