hubot で configで指定している以外のチャンネルでhearした場合につぶやかないスクリプト。最初に読まれるように _ とかでファイル名を始める

config = require 'config'
_ = require 'lodash'

module.exports = (robot) ->
  robot.hear /.*/, (msg) ->
    if _.contains config.roomLimit.specialUsers, msg.envelope.user.name
      return

    unless _.contains config.roomLimit.rooms, msg.envelope.room
      # see https://github.com/github/hubot/issues/200
      msg.finish()

    if /bot/.test msg.envelope.user.name
      msg.finish()

configはこんなかんじ

roomLimit:
  specialUsers:
    - 'manaten'
  rooms:
    - 'room1'
