nomnom

nomnom is a small option parser for node and CommonJS. It just parses your args and gives them back to you in a hash.

var nomnom = require("nomnom");

var opts = {
  config: {
    string: '-c PATH, --config=PATH',
    default: 'config.json',
    help: 'JSON file with tests to run'
  },
  debug: {
    string: '-d',
    help: 'Use debug mode'
  }
};

var options = nomnom.parseArgs(opts);

if(options.debug)
  // do stuff

You don't even have to specify anything if you don't want to: var options = nomnom.parseArgs();

var url = options[0]; // get the first positional arg
var debug = options.debug // see if --debug was specified
var verbose = options.v // see if -v was specified

Install

for node.js and npm: npm install nomnom

More Details

By default, nomnom parses node's process.argv. You can also pass in the args: var options = nomnom.parseArgs(opts, {}, ["-xvf", "--atomic=true"])

All parsed arguments that don't fit the -a or --atomic format and aren't attached to an option are positional and can be matched on via the position: var opts = { filename: { position: 0, help: 'file to edit' } }; var options = nomnom.parseArgs(opts);

sys.puts(options.filename);

Values are JSON parsed, so --debug=true --count=3 --file=log.txt would give you: { debug: true, count: 3, file: "log.txt" }

Nomnom prints out a usage message if --help or -h is an argument. You can disable this with the printHelp flag and specify the printing function with printFunc if you're not using node:

nomnom.parseArgs(opts, {printHelp: false});
