Best CLI arg parser for use in Rust to port from Perl with Getopt::Long?

• command-line-rust

  38 1,297 7.0 Rust

  Code for Command-Line Rust (O'Reilly, 2022, ISBN 9781098109417) https://learning.oreilly.com/library/view/command-line-rust/9781098109424/

Old-timey Perl guy here, and I second the use of clap. I have loads of examples at https://github.com/kyclark/command-line-rust if you want to copy.

• pico-args

  11 547 3.0 Rust

  An ultra simple CLI arguments parser.

If fewer dependencies is better, you can't get much fewer than pico-args, which has zero dependencies.

• getopts-long-rs

  1 0 3.5 Rust

  Rust cli options parsing library inspired by Perl's Getopt::Long

A direct port seems to just be a stub: https://github.com/salewski/getopts-long-rs
