Crate simple_cli_parser

A crate for parsing commands and arguemnts passed to the console.

This can parse commands with various arguments. It currently only supports option arguments (or args beginning with a “-”), but an update for regular params and argument rules (like ordering) will be coming soon.

Getting Started

To start, create a new Parser struct and add a couple of Args to it using the Parser::add_arg() or Parser::add_args() methods. Then, call the Parser::parse() method with std::env::Args passed in.

use cli_parser::{ Parser, Arg };
use std::env;
 
fn main() {
    let parser = Parser::new();
    let my_arg = Arg::new().flag("help").short('h');
    parser.add_arg(my_arg);
     
    let mut args = env::args();
 
    // Don't include the first argument
    args.next();
     
    let hashmap = parser.parse(&mut args).unwrap();
 
    if hashmap.contains_key("help") {
        println!("Help argument called!");
    }
}

Structs

Arg

Represents a single argument which can be passed to a Parser.

Parser

A struct that parses the command line for certain Args.
