medusa

General template for building command line interface (CLI) using (and written in) Rust

How to use

• Add crates dependencies in your Cargo.toml

...

[dependencies]
medusa = "0.1.0"
...

• Import the library

...
use medusa::{CommandLine, HandlerVariant};
...

• Create example function as your CLI option handler

...
fn hello() {
  println!("Hello, world!");
}

fn echo(payload: String) {
  println!("payload : {}", payload);
}
...

• Create your handler using HashMap

...
use std::collections::HashMap;

let mut handlers: HashMap<String, HandlerVariant> = HashMap::new();
handlers.insert(String::from("--hello"), HandlerVariant::Plain(hello));
handlers.insert(String::from("--echo"), HandlerVariant::WithArg(echo));
...

• Register your handler into CLI command

...
use std::env;

let mut command: CommandLine = CommandLine::new();
command.set_handler(handlers);
command.run(env::args());
...

• Test your Rust code if it's really works

cargo run -- --hello
cargo run -- --echo something

• Compile your code

cargo build
