Handling top level command

Maybe I’m missing something, but how do I handle the top level command?

args
  .command('a', 'Import data', a)
  .command('b', 'Export data', b)

This will run a or b if I run ./cmd a or ./cmd b.

But if I run ./cmd, it’s hanging (cause my script opens db connection), how do I a) print help or b) execute some code?

No. I will post a reproducible example shortly.

Hey @KidkArolis https://github.com/KidkArolis you can show the Help on your main command (with no arguments) with this function: .showHelp(). It is listed in the Docs: [image: Bildschirmfoto 2019-06-29 um 12 20 01] https://user-images.githubusercontent.com/8714775/60382775-40720000-9a68-11e9-8403-f3c5e09a3350.png

Does this fix your problem?

Here’s what I mean, taking the example from README (slightly modified):

#!/usr/bin/env node

const args = require('args')

args
  .option('port', 'The port on which the app will be running', 3000)
  .option('reload', 'Enable/disable livereloading')
  .command('serve', 'Serve your static site', serve, ['s'])

const flags = args.parse(process.argv)

function serve () {
  console.log('serving...')
}

This works fine:

$ ./hello serve
serving...
$ 

But how do I make sure that the following executions print help:

$ ./hello badcommand
$

$ ./hello
$

I’m thinking… perhaps loop over args.details.commands to match sub against each command…
