path-array

Treat your $PATH like a JavaScript Array

This module provides a JavaScript Array implementation that is backed by your $PATH env variable. That is, you can use regular Array functions like shift(), pop(), push(), unshift(), etc. to mutate your $PATH.

Also works for preparing an env object for passing to child_process.spawn().

Installation

Install with npm:

$ npm install path-array

Example

Interacting with your own $PATH env variable:

var PathArray = require('path-array');

// no args uses `process.env` by default
var p = new PathArray();

console.log(p);
// [ './node_modules/.bin',
//   '/opt/local/bin',
//   '/opt/local/sbin',
//   '/usr/local/bin',
//   '/usr/local/sbin',
//   '/usr/bin',
//   '/bin',
//   '/usr/sbin',
//   '/sbin',
//   '/usr/local/bin',
//   '/opt/X11/bin' ]

// push another path entry. this function mutates the `process.env.PATH`
p.unshift('/foo');

console.log(process.env.PATH);
// '/foo:./node_modules/.bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin'

API

new PathArray([env]) → PathArray

Creates and returns a new PathArray instance with the given env object. If no env is specified, then process.env is used by default.
