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.
```rust // ... ignore the imports for now ...
struct MyApp;
/// Describe your application with style ✨
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) ```
