davargs

This is the arguments processor that I use in my CLI tools. It is a very small wrapper around nopt to help with setting up defaults and sanatizing a little logic.

usage

var davargs = require('davargs');
 
davargs.init({
    known: {
        foo: Boolean,
        baz: Boolean,
        bar: String
    },
    shorts: {
        b: ['--bar']
    },
    on: ['foo'],
    off: ['baz']
});
 
var options = davargs.parse(process.argv);
console.log(options);
 

{ foo: true, help: false, version: false, baz: false }

options

The init function allows for this config

• known - The known object to use with nopt
• shorts - The shorts object to use with nopt
• on - An array of keys for the known object to set to true by default
• off - An array of keys for the known object to set to false by default

There is also a provided has method to check to see if an argument has been passed on the cli reguardless of whether it's true or false. Useful when passing arguments down a layer to a subprocess.
