Lightweight library to build command-line application (single-command app yet).

Features

• Supported flag value types:

  • string
  • int, int[8,16,32,64]
  • uint, uint[8,16,32,64]
  • float[32,64]
  • time.Duration
  • bool
  • counter (which has value of type int under the hood)
  • slices of all types in above, except counter

• Allows to create custom-typed (generic) flags with user-defined input parser (see example).

• Allows to override default parser for built-in flag types.

Future plans

• Add help/usage rendering for flag set
• Add Command type to allow multi-command applications
