MyCLI

A simple rust cli library inspired by clap builder.

Usage

$ cargo add my_cli

or

$ git clone git@github.com:MarcosAndradeV/my_cli.git # Just copy an paste into your project. :)

Example

use my_cli::*;

fn main() {
    let cl = MyCLI::create_from_args()
        .add_cmd("say",
            Cmd::new().arg("msg", 0)
            .flag_bool("-d")
            .help("Prints the message.")
        )
        .add_cmd("sayTo",
            Cmd::new()
            .arg("msg", 0)
            .flag("-t", "NAME", true)
            .help("Prints the message to <NAME>.")
        );
    match cl.get_matches() {
        Some(("say", flags, args)) => {
            if let Some(msg) = args.get(0) {
                if flags.is_present("-d") {
                    println!("DEBUG: You say: \"{msg}\"");
                } else {
                    println!("You say: \"{msg}\"");
                }
            } else {
                println!("ERROR: Expected msg");
            }
        }
        Some(("sayTo", flags, args)) => {
            if let Some(msg) = args.get(0) {
                if let Some(name) = flags.get("-t") {
                    println!("You say: \"{msg}\"\nTo: {name}");
                } else {
                    println!("You say: \"{msg}\"");
                }
            }
        }
        _ =>  cl.usage(),
    }
