Node: badargs is not 1.0 yet, so it may change at any time. Use it with caution.
badargs
A zero-dependency full type-safe argument parser.
It's correct enough for what it does.
badargs
handles non Utf8 input by just printing an error and exiting the program gracefully.
How to use
use arg;
arg!;
arg!;
arg!;
Use the badargs::arg!
macro to declare arguments like this:
arg!(Binding, long_name, optional_short_name -> return_type)
The following return types are currently available:
- String
- bool
- isize
- usize
- f64
Boolean values can only be None
or Some(true)
.
The other values can be None
or Some(_)
Todo
Being able to add more metadata for better --help
or --version
Why doesn't badargs have x?
If you want a fully featured, even more type safe argument parser, use Clap, or structopt.
These do have a lot of dependencies and/or proc macros, so they are a lot more heavy compilation wise. Badargs is perfect for you if you don't want or need that.
