sendak-usage

sendak-usage

It became clear after writing the bulk of Sendak's command-line components that a common "header" accompanied each task that included the command-line options, their long- and short- arguments, defaults, and descriptions, from which nopt-usage would generate a "usage" statement and nopt would do the actual parsedown into a hash.

But this was big and sprawling and when @konklone said to me that he uses minimist, I was peeved because I wanted to be able to switch and realised I had coded myself into this nopt and nopt-usage-shaped corner where I could not just forklift in minimist if I wanted to.

Accordingly I wrote this tiny package to abstract away the command-line parser I am using with usage stuff into a single hash so that I am not dependent on the vagaries of other packages (ahem, looking at you, nopt-usage…) that may or may not be actually maintained.

It is published here primarily so that Sendak can require it, but you should feel comfortable that it will continue to be maintained for at least as long as Sendak is if it is useful to you.

Usage

From the original issue:

var parsed = require( 'sendak-usage' ).parse( {
  // This is a full argument declaration
  //
  'help': {
    'long-args': [ 'help', 'halp' ],
    'description': 'sets the helpful bit',
    'short-args': [ 'h' ],
    'default': false
    'type': [ Boolean ]
  },
  // But all you need to do is specify the type of argument you want.
  //
  'long-arg-name': { 'type': [ Boolean ] }
} );
