如何让Hubot了解聊天环境？

Question

有没有办法让Hubot理解消息之间的对话背景？这样他可以问我澄清问题吗？

例如:

me: hey, create a branch plz
Hubot: How should I name it?
me: super-duper
Hubot: Branch 'super-duper' created

我应该使用某种状态机吗？有什么建议吗？

你可以使用机器人的大脑来保持状态.

robot.respond /hey, create a branch plz/i, (res) ->
     res.reply "Ok, lets start"
     user = {stage: 1}
     name = res.message.user.name.toLowerCase()
     robot.brain.set name, user

robot.hear /(\w+)\s(\w+)/i, (msg) ->
     name = msg.message.user.name.toLowerCase()
     user = robot.brain.get(name) or null
     if user != null
      answer = msg.match[2]
      switch user.stage
        when 1 
          msg.reply "How should I name it?"
        when 2 
          user.name = answer
          msg.reply "Are you sure (y/n) ?"
        when 3
          user.confimation=answer

      user.stage += 1
      robot.brain.set name, user

      if user.stage > 3 #End of process
        if /y/i.test(user.confimation) 
           msg.reply "Branch #{user.name} created." 
        else
           msg.reply "Branch creation aborted"

        robot.brain.remove name
