argv-lite

A lightweight, ergonomic command-line argument parser for Rust.

Features

• Simple and intuitive API for parsing command-line arguments
• Derive macro support for struct-based argument parsing
• Zero dependencies for core parsing
• Fast compile times and minimal runtime overhead

Usage

Add to your Cargo.toml:

[dependencies]
argv-lite = "0.1"

Example

use argv_lite_derive::ArgvLite;

#[derive(ArgvLite)]
struct Args {
    #[arg(short = 'v', long = "verbose")]
    verbose: bool,

    #[arg(short = 'o', long = "output")]
    output: Option<String>,
}

fn main() {
    let args = Args::parse();
    if args.verbose {
        println!("Verbose mode enabled");
    }
    if let Some(output) = args.output {
        println!("Output file: {output}");
    }
}
