## 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.

> <img width="400" src="/screen.png">

* bash-completion shortcuts for commands and options.
* and [tons more](/docs/api.md).

## Installation

Stable version:
```bash
npm i yargs
```

Bleeding edge version with the most recent features:
```bash
npm i yargs@next
```

## Usage :

### Simple Example

```javascript
#!/usr/bin/env node
const {argv} = require('yargs')

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

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

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

### Complex Example

```javascript
#!/usr/bin/env node
require('yargs') // eslint-disable-line
  .command('serve [port]', 'start the server', (yargs) => {
    yargs
      .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'
  })
  .argv
```

Run the example above with `--help` to see the help for the application.
