cmd.js

A lightweight library for parsing arguments in a command line interface (CLI).

Usage

Import this library

const {CommandParser, Command, HelpCommand} = require('cmdjs');

Create a command parser

const parser = new CommandParser();

Add some commands

const myCommand = new Command(['hi', 'hello'], '<name> - Says Hello!', args => {
  console.log("Hello, " + args[0] + "!");
});
parser.addCommand(myCommand);

Create a help command:

parser.addCommand(new HelpCommand('This is a hello test!', parser));

Then parse some arguments:

parser.parse(['help']);
parser.parse(['hi', "World"]);

This should return:

This is a hello test!
    hi,hello <name> - Says Hello!
Hello, World!
