This is intended to replace the runtime usage parser and is not meant to be a complete API in of itself, like `clap_app!`. What is in scope is everything that visually makes sense as in a usage string (see [docopt](http://docopt.org/) for inspiration). General setting of attributes is out of scope. This deviates from both `clap_app` and the runtime usage parser - `clap_app` supported multiple values but has a bug because we made `Arg::value_name` non-appending, so we aren't supporting this yet - We do not yet support optional flags that take a value - In both, `...` is multiple occurrences and values while its only multiple occurrences for us - We explicitly support optional values for flags - Unlike `clap_app`, our name is optional - Unlike runtime usage parser, our name syntax is simpler - Unlike runtime usage parser, our name syntax does not allow modifiers Its more limited than I would like. Hopefully some people better with macros can expand the feature set and turn more runtime errors into compile-time errors. This is to prepare for deprecating the runtime usage parser (#8). |
