pino_argparse

a tiny zero-dependency argparsing library

MIT/Apache 2.0

pino_argparse is a bite-sized argparsing library that can handle short and long flags with or without values, subcommands and basic validation.

USING IN YOUR PROJECT

add the follow to your Cargo.toml:

pino_argparse = { git = "https://github.com/MrPicklePinosaur/pino_argparse" }

TODO

  • auto doc/help message generation?
  • iterator to give flags in order

lib.rs:

A simple arg parsing library with no dependencies.

Provide a schema for your cli application and attach handlers to each command. Query for flags values with support for short and long flag names, as well as optional parameters.

use pino_argparse::{Cli, Flag, FlagParse, Command};

fn main() {

    // Get arguments
    let args = std::env::args().collect();

    // Initialize the CLI
    let cli = Cli {
        program_name: "myprogram",
        synopsis: "a simple program to show of the argparse library",
        root_command: Command {
            flags: vec![
                Flag::new("help").short('h'),
                Flag::new("verbose").short('v'),
            ],
            handler: |flagparse: FlagParse| -> Result<(), Box<dyn std::error::Error>> {
                if flagparse.get_flag("help") {
                    println!("We called the help flag!");
                }

                Ok(())
            },
            ..Default::default()
        },
        ..Default::default()
    };

    // Run the CLI
    let flagparse = cli.run(&args).unwrap();
}

No runtime deps
