arguably 0.9.0

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

# use arguably::ArgParser;
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") {
println!("Found --foo/-f flag.");
}

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

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