optparse-applicative-0.14.3.0: Utilities and combinators for parsing command line options

optparse-applicative is a haskell library for parsing options on the command line, providing a powerful applicative interface for composing these options.

optparse-applicative takes care of reading and validating the arguments passed to the command line, handling and reporting errors, generating a usage line, a comprehensive help screen, and enabling context-sensitive bash completions.

See the included README for detailed instructions and examples, which is also available on github https://github.com/pcapriotti/optparse-applicative.
