A simple catchall script for Hubot to process anything it doesn't know how to handle via Wolfram|Alpha

catchall.coffee

Wolfram = require('wolfram-alpha').createClient(process.env.HUBOT_WOLFRAM_APPID)

module.exports = (robot) ->
  robot.catchAll (msg) ->
    r = new RegExp "^(?:#{robot.alias}|#{robot.name}) (.*)", "i"
    matches = msg.message.text.match(r)
    if matches != null && matches.length > 1
      Wolfram.query matches[1], (e, result) ->
        if result and result.length > 0
          msg.send result[1]['subpods'][0]['text']
        else
          msg.send 'Beats me'

    msg.finish()
