Crate arguably

A minimalist library for parsing command line arguments.

Features

• Long-form boolean flags with single-character shortcuts: --flag, -f.
• Long-form string-valued options with single-character shortcuts: --option <arg>, -o <arg>.
• Condensed short-form options: -abc <arg> <arg>.
• Automatic --help and --version flags.
• Support for multivalued options.
• Support for git-style command interfaces with arbitrarily-nested commands.

Example

let mut parser = ArgParser::new()
    .helptext("Usage: foobar...")
    .version("1.0")
    .flag("foo f")
    .option("bar b");

if let Err(err) = parser.parse() {
    err.exit();
}

if parser.found("foo").unwrap() {
    println!("Found --foo/-f flag.");
}

if let Some(value) = parser.value("bar").unwrap() {
    println!("Found --bar/-b option with value: {}", value);
}

for arg in parser.args {
    println!("Arg: {}", arg);
}

Structs
