minimist

parse argument options (esm fork)

This is an ESM fork of minimist.

This module is the guts of optimist's argument parser without all the fanciful decoration.

example

import parseArgs from '@scg82/minimist';
const argv = parseArgs(process.argv.slice(2));
console.log(argv);

$ node example/parse.js -a beep -b boop
{ _: [], a: 'beep', b: 'boop' }

$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
{
	_: ['foo', 'bar', 'baz'],
	x: 3,
	y: 4,
	n: 5,
	a: true,
	b: true,
	c: true,
	beep: 'boop'
}

methods

import parseArgs from '@scg82/minimist';

const argv = parseArgs(args, opts={})

Return an argument object argv populated with the array arguments from args.

argv._ contains all the arguments that didn't have an option associated with them.

Numeric-looking arguments will be returned as numbers unless opts.string or opts.boolean is set for that argument name.

Any arguments after '--' will not be parsed and will end up in argv._.

options can be:

• opts.string - a string or array of strings argument names to always treat as strings
• opts.boolean - a boolean, string or array of strings to always treat as booleans. if true will treat all double hyphenated arguments without equal signs as boolean (e.g. affects --foo, not -f or --foo=bar)
• opts.alias - an object mapping string names to strings or arrays of string argument names to use as aliases
• opts.default - an object mapping string argument names to default values
• opts.stopEarly - when true, populate argv._ with everything after the first non-option

• opts['--'] - when true, populate argv._ with everything before the -- and argv['--'] with everything after the --. Here's an example:

  > parseArgs('one two three -- four five --six'.split(' '), { '--': true })
  {
    _: ['one', 'two', 'three'],
    '--': ['four', 'five', '--six']
  }

  Note that with opts['--'] set, parsing for arguments still stops after the --.

• opts.unknown - a function which is invoked with a command line parameter not defined in the opts configuration object. If the function returns false, the unknown option is not added to argv.

install

With npm do:

npm install @scg82/minimist
