argv-auto-glob

argv-auto-glob.js

automatically expand globs (cross-platform) for the process.argv array (or similar)

What is this?

Popular shells on macOS and Linux automatically expand globs prior to executing commands. However, the default shells on Windows do not.

This library checks a process.argv-like array of strings, detects any globs, and expands the globs. This is very convenient for developing consistent cross-platform CLI tools.

Usage

argvAutoGlob (argv, globOptions)

• argv: Array

• globOptions: see https://www.npmjs.com/package/glob#options

• returns Array

Example

We execute a Node.js script like so:

• node path/to/index.js **/*.txt

where our index.js file contains:

#! /usr/bin/env node
const argvAutoGlob = require('argv-auto-glob')
 
process.argv
// => (Windows) ['.../node', '.../index.js', '**/*.txt']
// => (bash/zsh) ['.../node', '.../index.js', 'example.txt', 'dir/more.txt', ... ]
 
process.argv = argvAutoGlob(process.argv)
 
process.argv
// => (all) ['.../node', '.../index.js', 'example.txt', 'dir/more.txt', ... ]
