ssb-bot is scuttlebot plugin to help make it easy to develop conversational user interfaces, similar to a Slack bot or a Facebook Messenger bot.

example

var bot = Bot({
  name: 'greeter',
  version: '0.0.0',
  initBot: (sbot) => {
    var { id } = sbot.whoami()
    var hasMentionForBot = hasMentionFor(id)

    return {
      handleMessage,
      handleAction
    }

    function handleMessage (state, message) {
      if (hasMentionForBot(message)) {
        return {
          state,
          action: {
            type: 'hello',
            id: message.value.author
          }
        }
      }

      return { state }
    }

    function handleAction (action, sbot, cb) {
      var { type } = action
      if (type === 'hello') {
        var { id } = action
        sbot.about.get((err, abouts) => {
          if (err) return cb(err)
          var name = abouts[id].name[id][0]
          cb(null, {
            type: 'post',
            text: `hello [@${name}](${id})!`,
            mentions: [
              {
                name,
                link: id
              }
            ]
          })
        })
      }
      else cb()
    }
  }
})

see example.js for the full example source.

with your main Scuttlebutt client (such as Patchwork) running, run node example, which should create a new bot who will request to replicate with your current feed.

if you @mention this new bot, it should respond with hello ${name}!

(you may need to restart the bot once or twice after sending a message)

why?

@mix brought up the idea of developing systems butt-first: %3MS64b+lB4Dk5gag8tJKnA+zy8BEQ2cLmyxF06sBKyM=.sha256. with this approach, we use ssb as a database, where a "api call" is publishing a message to your feed and a "database transaction" is the bot publishing a message to their feed.

i want to make it easier for people to create pub invites, as currently the only way is for a pub owner to ssh into their server and run sbot invite.create 1. (easy-ssb-pub gets around this by allowing anyone to create an invite from a public webpage, but i want something to help the network grow with personal invites.)

so i'm interested in a conversational approach to creating invites. i want to be able to private message a pub and say "hey can i have an invite?" and the pub responds with "sure, here you go: .... !"

how?

inspired by Elm or inu:

a bot is two functions:

handleMessage receives the current state and the next message, returns the next state and any new actions.

var handleMessage = (state, message) => {
  return {
    state: nextState,
    action
  }
}

handleAction receives the new action and asyncronously returns (via the callback) a new message to publish.

var handleAction = (action, sbot, callback) => {
  var content = {
    type: 'post',
    text: 'did i hear something?'
  }
  cb(null, content)
}
