argparse is a whole parser. it makes more sense to use clap bindings for parsing this type of input in Rust

[naturallymitchell]

I think we mainly need this issue https://docs.rs/clap/2.32.0/clap/struct.App.html#method.get_matches_safe

[naturallymitchell]

afaict, we need clap.from_yaml(), clap.get_matches_safe(), usage and help. anything else? and would it work?

[naturallymitchell]

question of would it work, how do we pass the get_matches_safe() to lua?

[juchiast]

How will you use the result of get_matches_safe() in lua?
