Interested in doing something like this for Julia?

Hello Xonsh community! I think this is a fantastic idea and a great way to build up an integrated system for python and shell commands! I wanted to ask if anyone here can make any recommendations on how I could start developing something like this for julia? My biggest concern is Julia's TTFX (Time to first execution) due to procompilation, and I was wondering if anyone would recommend for or against this?

If it's a go, please let me know if there are recommendations on how to set up a repository. I would like to keep this as close to Xonsh philosophy as possible!

Xonsh shell has it's own implementation of parser/tokenizer that is a superset of Python. So first step is to have parser/tokenizer for Julia.

I recommend you to talk with LLM (Claude/Copilot) about how Xonsh shell is working. Bash is a POSIX shell. What you see in Xonsh as command execution is not Bash. Xonsh has it's own commands parser as addition to Python parser. When you run echo @(2+2) it's not Bash command. The parser transforms the command to tokens and then executor builds command pipeline that will be executed using OS primitives. This is why Xonsh is shell and so powerfull.

Thank you for the clarification! Under the hood, is it running any bash at all, is it all python, or is it running something different altogether?

Is this something that required you to develop your own treesitter-style grammar? Just curious as to what might be required in this context...

Xonsh code is pure cross-platform Python both for command execution and syntax parsing.

Ok, this makes a bit more sense, so python does the parsing and the execution? So, as I understand it, you built your parser in python? Thanks for your time in explaining this to me, Andy!
