⚡ Zero-boilerplate commandline argument parsing in Rust

Project maintained by rust-cli Hosted on GitHub Pages — Theme by mattgraham

Build status Docs.rs



Write simple commandline applications in Rust with zero boilerplate. Bind Rust functions to CLI functions and options with macros. This crate uses clap.rs for the actual argument parsing.

Example

// ... ignore the imports for now ...

struct MyApp;

/// Describe your application with style ✨
#[thunderclap]
impl MyApp {
    /// Say hello to someone
    fn hello(name: &str) {
        println!("Hello {}", name);
    }
}

fn main() {
    MyApp::start();
}

This prints

USAGE:
    MyApp [SUBCOMMAND]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

SUBCOMMANDS:
    hello    Say hello to someone
    help     Prints this message or the help of the given subcommand(s)
