RequiredOption is undefined, when no value is passed to the command

[benwinding]

I'm getting an issue where a requiredOption is undefined, when no value is passed to the command.

Code

program
  .command('build')
  .requiredOption('-c, --config', 'Configuration Name')
  .action(async function (env, options) {
// options is undefined
  });

Args

$ ./mycommander build -c

Result

options is undefined

Expected

I would expect requiredOption to be an option that enforces a value, not just the flag to be present

Ps: Love the library, it's pretty nice to work with 👍

1. Your build command does declare any arguments, so the first parameter passed to the action handler will be the options.

program
   .command('build')
   // ...
   .action(async function (options)

From the README (https://github.com/tj/commander.js#action-handler-subcommands):

The action handler gets passed a parameter for each argument you declared, and one additional argument which is the command object itself. This command argument has the values for the command-specific options added as properties.

2. From its description, it sounds like your option expect a value. This might just be a typo in your example, but in case it causes confusion:

.requiredOption('-c, --config <name>', 'Configuration Name')

Ahh I see now, works as expected.

Thanks @shadowspawn!
