在Hubot脚本中调试/打印

Question

I'm trying to debug an existing Hubot script and in the future write my own, and I need an easy way to debug it or at least print values somewhere (but not to the channel). How can I do so?

Bonus points if this can be done with just using Node in some interactive local mode. I'm really not sure where to start.

All scripts Hubot uses are written in Coffeescript.

PS I'm using Hubot with Hipchat.

Answer 1

I don't know if this helps but I found a way to inspect objects.

Util = require "util"

module.exports = (robot) ->
  robot.hear /hi robot/i, (msg) ->
    user = robot.brain.usersForFuzzyName(msg.message.user.name)
    msg.send "#{Util.inspect(user)}"

This allowed be to see all the elements of the object so I could figure out what I was doing wrong...

Answer 2

我自己发现了答案：.coffee Coffeescript源中的console.log MSG正是我所需要的。

Answer 3

You can use

robot.logger.info "your log message here"

That will log it just like the other hubot messages get logged.

Answer 4

发现这个（coffeescript）片段记录了所有错误，非常有助于添加到开发中的机器人。

robot.error (err, res) -> robot.logger.error "#{err}\\n#{err.stack}" if res? res.reply "#{err}\\n#{err.stack}"
