generate shell completion from specs

I'm curious how hard this would be.
Maybe have a special flag --complete that takes a partial command line and returns the list of completions to the shell.

Feel free to experiment. I'm open to this, but I think completions are shell (bash, zsh, fish, etc) specific?

[millettjon]

Cool.

zsh apparently has a bash compatibility mode. I'm not sure about fish.

My inspiration for this is the compleat tool which does something similar and works with bash, zsh, and fish.

Idea for API:

(babashka.cli/complete {:shell :zsh :dispatch-table dispatch-table})

Then the user can choose to map --complete or complete or something else at their own leisure :)

Unknowns / uncertainty: I have only ever used babashka.cli/dispatch for my use. Not all CLIs are built around a dispatch table. I suppose a general solution would be better.
