subarg

parse arguments with recursive contexts using minimist

testling badge

build status

This module is useful if you need to pass arguments into a piece of code without coordinating ahead of time with the main program, like with a plugin system.

example

var subarg = require('subarg');
var argv = subarg(process.argv.slice(2));
console.log(argv);

Contexts are denoted with square brackets:

$ node example/show.js rawr --beep [ boop -a 3 ] -n4 --robots [ -x 8 -y 6 ]
{ _: [ 'rawr' ],
  beep: { _: [ 'boop' ], a: 3 },
  n: 4,
  robots: { _: [], x: 8, y: 6 } }

methods

var subarg = require('subarg')

var argv = subarg(args, opts)

Parse the arguments array args, passing opts to minimist.

An opening [ in the args array creates a new context and a ] closes a context. Contexts may be nested.

install

With npm do:

npm install subarg
