Usage

// import the crate
use optparse;

// functions/closures must take String as their only parameter
// and not return anything
fn hello(arg: String) {
    println!("Hello {} \\o/", arg);
}
fn main() {
    // create a new parser with a parser description
    let mut parser = optparse::Parser::new("Example Description");

    // register a flag and a corresponding function to be called
    // from the command line
    // register!(flag, command description, function/closure, parser);
    optparse::register!("-welcome", "Example Description", hello, parser);

    // run the parser using the arguments from std::env
    // parse!(arguments, arguments length, parser)
    let args: Vec<String> = std::env::args().collect();
    optparse::parse!(args.clone(), args.len() as u8, parser);
}

Work in Progress

• aliasing
• single flag parsing
• multi parameter closures
