argvark
Intuitive command-line argument parsing for Node.js modules.
Install
npm install argvark
Usage
> node some-module -p --age=123 --name="John Doe"
var argv = require('argvark');
// Simple matches:
p = argv('-p'); // '-p'
// Verbose Parameters:
age = argv(/--age=(\d+)/) // 123
name = argv(/--name="(.+?)"/) // 'John Doe'
Use after() when the value is separated from the param by a space:
> node some-module port 8888
argv.after('port') // 8888
Use flag() when you want a Boolean value indicating the flag presence, or when
you don't want to build your own pattern just to check flags. This uses !!argv(/-\w+[FLAG]/)
so it supports both standard flag formats:
> node some-module -abCD
> node some-module -a -b -C -D
argv.flag('b') // true
argv.flag('D') // true
argv.flag('X') // false
Unmatched patterns evaluate to undefined
location = argv('--location') // undefined
Making changes
Just run npm test
to make sure everything is still working. Add tests for
fixes etc.
