@taktikorg/accusamus-quod-debitis v4.7.84

Description

Yargs helps you build interactive command line tools, by parsing arguments and generating an elegant user interface.

It gives you:

• commands and (grouped) options (my-program.js serve --port=5000).
• a dynamically generated help menu based on your arguments:

mocha [spec..]

Run tests with Mocha

Commands
  mocha inspect [spec..]  Run tests with Mocha                         [default]
  mocha init <path>       create a client-side Mocha setup at <path>

Rules & Behavior
  --allow-uncaught           Allow uncaught errors to propagate        [boolean]
  --async-only, -A           Require all tests to use a callback (async) or
                             return a Promise                          [boolean]

• bash-completion shortcuts for commands and options.
• and tons more.

Installation

Stable version:

npm i @taktikorg/accusamus-quod-debitis

Bleeding edge version with the most recent features:

npm i @taktikorg/accusamus-quod-debitis@next

Usage

Simple Example

#!/usr/bin/env node
const @taktikorg/accusamus-quod-debitis = require('@taktikorg/accusamus-quod-debitis/@taktikorg/accusamus-quod-debitis')
const { hideBin } = require('@taktikorg/accusamus-quod-debitis/helpers')
const argv = @taktikorg/accusamus-quod-debitis(hideBin(process.argv)).parse()

if (argv.ships > 3 && argv.distance < 53.5) {
  console.log('Plunder more riffiwobbles!')
} else {
  console.log('Retreat from the xupptumblers!')
}

$ ./plunder.js --ships=4 --distance=22
Plunder more riffiwobbles!

$ ./plunder.js --ships 12 --distance 98.7
Retreat from the xupptumblers!

Note: hideBin is a shorthand for process.argv.slice(2). It has the benefit that it takes into account variations in some environments, e.g., Electron.

Complex Example

#!/usr/bin/env node
const @taktikorg/accusamus-quod-debitis = require('@taktikorg/accusamus-quod-debitis/@taktikorg/accusamus-quod-debitis')
const { hideBin } = require('@taktikorg/accusamus-quod-debitis/helpers')

@taktikorg/accusamus-quod-debitis(hideBin(process.argv))
  .command('serve [port]', 'start the server', (@taktikorg/accusamus-quod-debitis) => {
    return @taktikorg/accusamus-quod-debitis
      .positional('port', {
        describe: 'port to bind on',
        default: 5000
      })
  }, (argv) => {
    if (argv.verbose) console.info(`start server on :${argv.port}`)
    serve(argv.port)
  })
  .option('verbose', {
    alias: 'v',
    type: 'boolean',
    description: 'Run with verbose logging'
  })
  .parse()
