Installation

Add this to your Cargo.toml:

[dependencies]
snap = "2.0.2"

Usage Here's a simple example of how to use Snap:

use snap_cli::{app::App, arg::Arg, command::Command};

fn main() {
    let matches = App::new("myapp")
        .version("1.0")
        .author("Your Name <your@email.com>")
        .about("Does awesome things")
        .arg("<input> 'Sets the input file to use'")
        .arg("-v, --verbose 'Sets the level of verbosity'")
        .get_matches();

    if let Some(input) = matches.value_of("input") {
        println!("Using input file: {}", input);
    }

    if matches.is_present("verbose") {
        println!("Verbose mode is on");
    }
}
