Async Messages

[codeiain]

The current source doesn't allow async msgs to be sent back from the brain scripts.

Changing the code for the coffee script to

RiveScript = require "rivescript"

module.exports = (robot) ->

  # Configuration parameters.
  brain  = process.env.HUBOT_RIVESCRIPT_BRAIN or "./brain"
  prefix = if process.env.HUBOT_RIVESCRIPT_PREFIX then "#{process.env.HUBOT_RIVESCRIPT_PREFIX}\\s+" else "\\s*"
  utf8   = "#{process.env.HUBOT_RIVESCRIPT_UTF8}" is "1" or false

  # The matcher regexp.
  regexp = new RegExp("#{prefix}(.*)", "i")

  # Initialize the RiveScript brain.
  @bot = new RiveScript({
    utf8: utf8
  })
  @bot.loadDirectory(brain, ->
    @bot.sortReplies()

    robot.respond regexp, (res) ->
      bot.replyAsync(res.message.user.name, res.match[1]).then (reply) ->
        res.send reply
        return

      #reply = bot.reply(res.message.user.name, res.match[1])
      #res.send reply
  , (err) ->
    console.error "Couldn't load RiveScript replies: #{err}"
  )

will allow async msgs to be sent back from the brain

I've published hubot-rivescript v0.1.1 which incorporates this change.

Async replies are on by default, and can be disabled with HUBOT_RIVESCRIPT_SYNC=1
