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 badargs::arg;

arg!(OutFile: "output", 'o' -> String);
arg!(Force: "force", 'f' -> bool);
arg!(OLevel: "optimize" -> usize);

fn main() {
    let args = badargs::badargs!(OutFile, Force, OLevel);

    let outfile = args.get::<OutFile>();
    let force = args.get::<Force>();
    let o_level = args.get::<OLevel>();

    println!("output:     {:?}", outfile);
    println!("force:      {:?}", force);
    println!("o-level:    {:?}", o_level);
    println!("other args: {:?}", args.unnamed())
    
}

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(_)

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.
