Crate klask

You can use run_app for Apps created manually or generated from yaml and run_derived for Apps derived from a struct. Both of these functions take a closure that contains the code that would normally be in main. They should be the last thing you call in main.

For example

fn main() {
    let app = App::new("Example").arg(Arg::new("debug").short('d'));
    klask::run_app(app, |matches| {
       println!("{}", matches.is_present("debug"))
    });
}

corresponds to

fn main() {
    let app = App::new("Example").arg(Arg::new("debug").short('d'));
    let matches = app.get_matches();
    println!("{}", matches.is_present("debug"))
}

Currently requires nightly.

Functions

run_app

Call with an App and a closure that contains the code that would normally be in main.

run_derived

Can be used with a struct deriving clap::Clap. Call with a closure that contains the code that would normally be in main. It’s just a wrapper over run_app.
