Customizations based on external logic

[subbeh]

I've been exploring options to customise the output of eza based on additional parameters.

For my use case, I'd like to be able to see if a file or directory is managed by chezmoi. A simple one-liner like test -z "$(chezmoi managed managed_file.txt)" can be used to get a return code of either 0 or 1.

Would it be an idea to add an option like --custom-cmd 'test -z "$(chezmoi {{ .filename }})' and --custom-icon <icon> to eza?

I'm mostly thinking out loud, but if this is something that could be useful other than for my niche scenario, I'd be happy to put some more thought into it.
