Slick - A Slack bot in Go

Slick is a Slack bot to do ChatOps and other cool things. Slick was originally developed here and has since been adopted by Capstone for internal use :)

• Simple API to message users privately
• Simple API to update a previously sent message
• Simple API to delete bot messages after a given time duration.
• Easy plugin interface, listeners with criteria such as:
  • Messages directed to the bot only
  • Private or public messages
  • Listens for a duration or until a given time.Time
  • Selectively on a channel, or from a user
  • Expire listeners and unregister them dynamically
  • Supports listening for edits or not
  • Regexp match messages, or Contains checks
• Built-in KV store for data persistence (backed by BoltDB and JSON serialization)
• The bot has a mood (happy and hyper) which changes randomly.. you can base some decisions on it, to spice up conversations.
• Supports listening for any Slack events (ChannelCreated, ChannelJoined, EmojiChanged, FileShared, GroupArchived, etc..)
• A PubSub system to facilitate inter-plugins (or chat-to-web) communications.

Stock plugins

1. Recognition: a plugin to recognize your peers (!recognize @user1 for doing an awesome job)

2. Faceoff: a game to learn the names and faces of your colleagues. The code for this one is interesting to learn to build interactive features with slick.

3. Vote: a simple voting plugin to decide where to lunch

4. Funny: a bunch of jokes and memes in reply to some strings in channels.. (inspired by Hubot's jokes)

5. Healthy: a very simple plugin that pokes URLs and reports on their health

6. Deployer: an example plugin to do deployments wth ansible (you'll probably want to roll out your own though).

7. Todo: todo list manager, one per channel

Local build and install

Try it with:

go get github.com/CapstoneLabs/slick
cd $GOPATH/src/github.com/CapstoneLabs/slick/example-bot
go install -v && $GOPATH/bin/example-bot

There's a Dockerfile and example configuration in the example-bot directory.

Writing your own plugin

Example code to handle deployments:

// listenDeploy was hooked into a plugin elsewhere..
func listenDeploy() {
	keywords := []string{"project1", "project2", "project3"}
	bot.Listen(&slick.Listener{
		Matches:        regexp.MustCompile("(can you|could you|please|plz|c'mon|icanhaz) deploy (" + strings.Join(keywords, "|") + ") (with|using)( revision| commit)? `?([a-z0-9]{4,42})`?"),
		MentionsMeOnly: true,
		MessageHandlerFunc: func(listen *slick.Listener, msg *slick.Message) {

			projectName := msg.Match[2]
			revision := msg.Match[5]

			go func() {
				go msg.AddReaction("work_hard")
				defer msg.RemoveReaction("work_hard")

				// Do the deployment with projectName and revision...

			}()
		},
	})
}

Take inspiration by looking at the different plugins, like Funny, Healthy, Storm, Deployer, etc.. Don't forget to update your bot's plugins list, like in example-bot/main.go
