"use strict"

var loremIpsum = require('lorem-ipsum')
var runner = require('../runner')

var words = loremIpsum({ count: 5, units:'words'})
  .replace(/([^\w ])/g, '')// remove non-words and spaces
  .toLowerCase() // lowercase I guess
  .split(' ') // create array of words

module.exports = runner.custom(function(slice, words) {
  var result = []
  words.forEach(function(word) {
    result.push('word:', word);
    result.push('slice(word):', slice(word))
    result.push('slice(word, 0, 1):', slice(word, 0, 1))
    result.push('slice(word, 2):', slice(word, 2))
    result.push('slice(word, -1):', slice(word, -1))
  })
  return result
})(words)
