nopt wrapper with commander-like API

noptify is a little wrapper around nopt module adding a more expressive, commander-like, API and few helpers.


 var program = noptify(process.argv, { program: 'name' })
   .option('port', '-p', 'Port to listen on (default: 35729)', Number)
   .option('pid', 'Path to the generated PID file', String)

 var opts = program.parse();

Returns an instance of Noptify

Noptify provides the API to parse out option, shorthands and generate the proper generic help output.

  • args - The Array of arguments to parse (default: process.argv);
  • options - An hash of options with the following properties
    • program - The program name to use in usage output

Every noptify instance is created with two options, -h, --help and -v, --version.

Parse the provided options and shorthands, pass them through nopt and return the result.

When is set, the help output is displayed and help event is emitted. The process exists with 0 status, the help output is automatically displayed and the help event is emitted.


var program = noptify(['foo', '--help'])
  .on('help', function() {
    console.log('  foo bar --baz > foo.txt');

var opts = program.parse();
// ... Help output ...
// ... Custom help output ...
// ... Exit ...

Define the program version.

Define name option with optional shorthands, optional description and optional type.

Simply output to stdout the Usage and Help output.
