  • Trollop

    Optimist is a commandline option parser for Ruby that just gets out of your way.

    • My favorite is probably trollop but I haven’t needed to write a cli in years. Clap is also great, but the best I’ve used is probably Click which is saying something because I absolutely hate Python. Also deploying is a completely separate problem from which library is best. Click is by far the worst to deploy, then Clap, then trollop.

  • clap-rs
