What sort of info about default values are you looking for?

There are a coupe of examples of default values for options that are covered without additional explanation in the README:

  .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')

  .option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium')

Thanks. Yes I discovered them eventually, but at the moment I was interested to provide a default value in my app, I couldn't search for any explicitly mentioned default use case, but rather hitting:

.command('list', 'list packages installed', {isDefault: true})

or

If you want to display help by default ..

It would be nice to have more clear directions

And how can i set a option on by default. For example I have an option --databaseHost which should have a default value. How can I do this? This is without an enum.

I am looking similar to set default value for the parameters.

I used package argparse before, and it is easy to set the default value, how can I do the same with commander?

bar.addArgument(
  [ '-f', '--foo' ],
  {
    action: 'store',
    defaultValue: "test.txt",
    help: 'foo3 bar3'
  }
);

@ozbillwang

  .option('-f, --foo <value>', 'foo3 bar3', 'test.txt')

I have proposed a large update to options coverages in README in #953

Updated README to clarify option types, including section for default option value
