#!/usr/bin/env node

const parser = require('tiny-cli-parser').tinyCliParser
const validate = require('tiny-cli-parser').validateArgs

const cli = parser()

// cli    - parsed argv as above
// ['-p'] - option flag that cannot be null
// 1      - minimum number of args
if (!validate(cli, ['-p'], 1)) {
    console.log('validation error!', cli)
} else {
    console.log('passed validation!')

Jasons-MBP:example jasonchild$ ./example.js -p flag1
validation error! { options: [ { flag: '-p', value: 'flag1' } ],
  args: [],
  count: 4 }
Jasons-MBP:example jasonchild$ ./example.js arg1 -p
