Sade says it's in single mode when single mode is explicitly disabled

[daniel sieradski]

My code:

const app = async () => {
  consola.log(tagline)
  const bus = new EventEmitter()

  try {
    const cli = sade('udd <command> [options]', false)

    // configure the cli options
    cli
      .version('0.1.0')
      .option('-p, --project', 'Google Cloud Project ID')
      .option('-y, --confirm', 'Non-iteractive, confirm all actions')

    rollback(cli, bus)

    cli.parse(process.argv)
  } catch (err) {
    // fail gracefully
    consola.error(err)
    process.exit(1)
  }
}

The result, which I also get if I leave isSingle undefined:

 ERROR  Disable "single" mode to add commands                                     10:31:25

This works, though:

cli.single = true

Hey, so the documentation actually doesn't mention it (oops), but isSingle is always true when the usage text has a space in it: https://github.com/lukeed/sade/blob/master/lib/index.js#L10

The parameter is there for explicitly turning on single-command mode when, for example, you don't have custom usage text.

For your app, you should have this instead, since you're just redefining the default usage text (which is generated automatically):

cli = sade('udd');

cli.version('...')

Closing, but let me know if you have any follow-up questions 👍
