structopt

StructOpt

Parse command line arguments by defining a struct. It combines clap with custom derive.

Maintenance

As clap v3 is now out, and the structopt features are integrated into (almost as-is), structopt is now in maintenance mode: no new feature will be added.

Bugs will be fixed, and documentation improvements will be accepted.

See the structopt -> clap migration guide
