This is a Hubot adapter to use with Slack.

• npm install -g hubot coffee-script
• hubot --create [path_name]
• cd [path_name]
• npm install hubot-slack --save
• Initialize git and make your initial commit
• Check out the hubot docs for further guidance on how to build your bot

• ./bin/hubot

This is a modified set of instructions based on the instructions on the Hubot wiki.

• Make sure hubot-slack is in your package.json dependencies

• Edit your Procfile and change it to use the slack adapter:

    web: bin/hubot --adapter slack
  

• Install heroku toolbelt if you haven't already.

• heroku create my-company-slackbot

• heroku addons:add redistogo:nano

• Activate the Hubot service on your "Team Services" page inside Slack.

• Add the config variables. For example:

    % heroku config:add HEROKU_URL=http://soothing-mists-4567.herokuapp.com
    % heroku config:add HUBOT_SLACK_TOKEN=dqqQP9xlWXAq5ybyqKAU0axG
    % heroku config:add HUBOT_SLACK_TEAM=myteam
    % heroku config:add HUBOT_SLACK_BOTNAME=slack-hubot
  

• Deploy and start the bot:

    % git push heroku master
    % heroku ps:scale web=1
  

• Profit!

This adapter uses the following environment variables:

This is the service token you are given when you add Hubot to your Team Services.

This is your team's Slack subdomain. For example, if your team is https://myteam.slack.com/, you would enter myteam here.

Optional. What your Hubot is called on Slack. If you entered slack-hubot here, you would address your bot like slack-hubot: help. Otherwise, defaults to slackbot.

Optional. If you entered blacklist, Hubot will not post in the rooms specified by HUBOT_SLACK_CHANNELS, or alternately only in those rooms if whitelist is specified instead. Defaults to blacklist.

Optional. A comma-separated list of channels to either be blacklisted or whitelisted, depending on the value of HUBOT_SLACK_CHANNELMODE.

Optional. By default, Slack will not linkify channel names (starting with a '#') and usernames (starting with an '@'). You can enable this behavior by setting HUBOT_SLACK_LINK_NAMES to 1. Otherwise, defaults to 0. See Slack API : Message Formatting Docs for more information.

The slack adapter adds a path to the robot's router that will accept POST requests to:

/hubot/slack-webhook

Source: https://github.com/tinyspeck/hubot-slack/blob/2.2.0/src/slack.coffee#L161-L177

Expected parameters:

• text
• user_id
• user_name
• channel_id
• channel_name

If there is a message and it can deduce an author from those paramters, it'll create a new TextMessage object and have the robot receive it, from there proceeding down the regular hubot path.

When a script calls send() or reply() this adapter makes a POST request to your team's specific URL webhook:

https://<your_team_name>.slack.com/services/hooks/hubot

with a JSON-formatted body including the following dictionary:

• username
• channel
• text
• link_names (optionally)

Sometime, it's useful to send a message regardless of the channel's activity (like robot.hear or robot.response). Hubot has robot.messageRoom available for this use case.

Slack API uses channel ID's by default, which uses computer-friendly alphanumeric ID. To use the pretty names, prefix it with a hash.

robot.respond /hello$/i, (msg) ->
  robot.messageRoom '#general', 'hello there'
