This is a version of GitHub's Campfire bot, hubot. He's pretty cool.

You'll probably never have to hack on this repo directly.

Follow the instructions below and get your own hubot ready to deploy.

Getting Your Own

Make sure you have node.js and npm installed.

You can install the hubot npm package globally and you will be able to run hubot --create <PATH> if you've setup npm packages to be in your PATH.

$ npm install -g hubot coffee-script
$ hubot --create <path>

Then the directory at <path> contains a deployable hubot that you're able to deploy to heroku or run locally.


Adapters are the interface to the service you want your hubot to run on. This can be something like Campfire or IRC. There are a number of third party adapters that the community have contributed. Check the hubot wiki for the available ones and how to create your own.

Please submit issues and pull requests for third party adapters to the adapter repository, not this one (unless it's the Campfire or shell adapter).

Hubot Scripts

Hubot ships with a number of default scripts, but there's a growing number of extras in the hubot-scripts repository. hubot-scripts is a way to share scripts with the entire community.

Check out the README for more help on installing individual scripts.

External Scripts

This functionality allows users to enable scripts from npm packages which don't have to be included in the hubot-scripts repository.

To enable to functionality you can follow the following steps.

  1. Add the packages as dependencies into your package.json
  2. npm install to make sure those packages are installed

To enable third-party scripts that you've added you will need to add the package name as a double quoted string to the external-scripts.json file for your hubot.

Please note that external scripts may become the default for hubot scripts in future releases.

Creating A Script Package

Creating a script package for hubot is very simple. Start by creating a normal npm package. Make sure you add a main file for the entry point (e.g. index.js or index.coffee).

In this entry point file you're going to have to export a function that hubot will use to load the scripts in your package. Below is a simple example for loading each script in a ./scripts directory in your package.

Fs   = require 'fs'
Path = require 'path'

module.exports = (robot) ->
  path = Path.resolve __dirname, 'scripts'
  Fs.exists path, (exists) ->
    if exists
      robot.loadFile path, file for file in Fs.readdirSync(path)

After you've built your npm package you can publish it to npmjs.

HTTP Listener

Hubot has a HTTP listener which listens on the port specified by the PORT environment variable. If PORT is not specified, the default port will be 8080.

You can specify routes to listen on in your scripts by using the router property on robot.

module.exports = (robot) ->
  robot.router.get "/hubot/version", (req, res) ->
    res.end robot.version

There are functions for GET, POST, PUT and DELETE, which all take a route and callback function that accepts a request and a response.

In addition, if you set EXPRESS_STATIC, the HTTP listener will serve static files from this directory.


Hubot can also respond to events which can be used to pass data between scripts.

# src/scripts/github-commits.coffee
module.exports = (robot) ->
  robot.router.post "/hubot/gh-commits", (req, res) ->
    #code goes here
    robot.emit "commit", {
        user    : {}, #hubot user object
        repo    : 'https://github.com/github/hubot',
        hash  : '2e1951c089bd865839328592ff673d2f08153643'
# src/scripts/heroku.coffee
module.exports = (robot) ->
  robot.on "commit", (commit) ->
    robot.send commit.user, "Will now deploy #{commit.hash} from #{commit.repo}!"
    #deploy code goes here

If you provide an event, it's very recommended to include a hubot user object in data. In case of other reacting scripts want to respond to chat.


Hubot has first class support for specify roles which a user must have to run specific commands. If you wish you use this support you must set the the following environment variables:

* `HUBOT_AUTH_ADMIN` a comma separated list of admin IDs

You can find the user IDs by running the show users command. The admin IDs specify which users can add and remove roles from users. Please note you can only assign the admin role using the environment variable.

 Assigning a Role

You can assign a role to the user using the following command:

hubot Joe Bloggs has developer role
hubot John Doe has ops role

The name must be the exact name as stored in hubot's brain.

 Removing a Role

You can remove a role from the user using the following command:

hubot Joe Bloggs doesn't have developer role
hubot John Doe does not have ops role

Viewing a Users Roles

You can view the roles a user has or see which users have the admin role with the following commands:

hubot what roles does Joe Bloggs have?
hubot who has admin role?


Hubot has an in-memory key-value store exposed as robot.brain that can be used to store and retrieve data by scripts.

module.exports = (robot) ->

  robot.respond /have a beer/i, (msg) ->
    # Get number of beers had (coerced to a number).
    beersHad = robot.brain.get('totalBeers') * 1 or 0

    if beersHad > 4
      msg.respond "I'm too drunk.."

      msg.respond 'Sure!'

      robot.brain.set 'totalBeers', beersHad+1
      # Or robot.brain.set totalBeers: beersHad+1

If the script needs to store user data, robot.brain has a built-in interface for it.

module.exports = (robot) ->

  robot.respond /who is @?([\w .\-]+)\?*$/i, (msg) ->
    name = msg.match[1].trim()

    users = robot.brain.usersForFuzzyName(name)
    if users.length is 1
      user = users[0]
      # Do something interesting here..

      msg.send "#{name} is user - #{user}"
