argwerk
Helper utility for parsing simple commandline arguments.
This is not intended to be a complete commandline parser library. Instead this can be used as an alternative quick-and-dirty approach that can be cheaply incorporated into a tool.
We provide:
- A dependency-free commandline parsing framework using declarative macros. So it's hopefully lightweight and compiles quickly.
- A flexible mechanism for parsing.
- Formatting decent looking help messages.
We specifically do not support:
- As-close-to correct line wrapping with wide unicode characters as possible (see textwrap).
- Required arguments. If your argument is required, you'll have to
ok_or_else it yourself from an
Option<T>
. - Complex command structures like subcommands.
For a more complete commandline parsing library, use clap.
See the documentation for argwerk::parse! for how to use.
Examples
This is available as a runnable example:
let args = parse! ?;
dbg!;
