go-options - command line parsing library for Go

  • Easy to use - no boilerplate
  • Self-documenting - the spec turns into the usage string
  • Powerful - doesn't do everything you ever dreamed of, but comes close
  • Flexible - if you want control over parsing, provide your own callback.

This design is inspired by git rev-parse --parseopt and the discussion of bup.options here. There are some minor deviations.

  • On the code side, you must access the opt structure with canonical option names only. This is intended to reduce programmer errors. (This applies to the simple, non-callback interface.)
  • When I support negated options, I will not support unnegated aliases for them as that can lead to more confusion than I deem worth harboring.
