feat: export ENV vars command line clap2env tool about clap-serde HOT 4 OPEN

I believe there is a tool that wraps clap for use in bash. Not finding it atm but on mobile.

One challenge with the suggested approach is that the tool can't modify the outside environment. It could dump a script to be sourced or it can wrap a command.

will donate 100 USD in crypto for such tool :)

Yeah, I searched various terms, not found yet.

I am ok with Go/C/Zig/AOT compiled bytecode - as long as startup is fast.

I just found that clap seems fits as per clap-serde crate already does half of work.

yeah, i see.

so it can be something like:

# bash is bad here, but kind of this to work
source < $(clap2nix clap-config.toml $@)

and other option try work:

# so not clear how process reuse shell called it - seems not great until there is 100% portable robust cargo to handle that
clap2nix clap-config.toml $@ -- echo $SOME_PAR
