Readme

Provides tools to create command line parsers. The library has a simple interface to create atomic parsers and combine them into more complex structures. The interface has a low-level feel but still lets you solve common use-cases with minimal work.

Has support for:

  • Generating a help screen.

  • Multi-argument options.

  • Short flags with bundling.

  • Subcommands via <|>.

  • Parsing "in sequence" via <*> and "in parallel" via <#>.

  • Options with custom types via <$?>.

  • Monadic bind if you need it.
