Slack Smart Bot

Gem Version

Create a Slack bot that is really smart and so easy to expand.

The main scope of this ruby gem is to be used internally in your company so teams can create team channels with their own bot to help them on their daily work, almost everything is suitable to be automated!!

slack-smart-bot can create bots on demand, create shortcuts, run ruby code... just on a chat channel, you can access it just from your mobile phone if you want and run those tests you forgot to run, get the results, restart a server... no limits.

Installation and configuration

$ gem install slack-smart-bot

After you install it you will need just a couple of things to configure it.

Create a file like this on the folder you want:

# the channel that will act like the master channel, main channel
MASTER_CHANNEL="my_master_channel"
#names of the master users
MASTER_USERS=["mario"]

require 'slack-smart-bot'

settings = {
    nick: 'my_smart_bot', # the smart bot name
    token: 'xxxxxxxxxxxxxxxxxx' # the API Slack token
}

begin
  puts "Connecting #{settings.inspect}"
  SlackSmartBot.new(settings).listen
rescue Exception => e
  puts "Rescued: #{e.inspect}"
end

The MASTER_CHANNEL will be the channel where you will be able to create other bots and will have special treatment.

The MASTER_USERS will have full access to everything. The names should be written exactly the same like they appear on Slack.

For the token remember you need to generate a token on the Slack web for the bot user.

This is something done in Slack, under integrations. Create a new bot, and note its API token.

Remember to invite the smart bot to the channels where they will be accessible before creating the bot

Usage

creating the MASTER BOT

Let's guess the file you created was called my_smart_bot.rb so, just run it:

ruby my_smart_bot.rb

After the run, it will be generated a rules file with the same name but adding _rules, in this example: my_smart_bot_rules.rb

The rules file can be edited and will be only affecting this particular bot.

You can add all the rules you want for your bot in the rules file, this is an example:

def rules(user, command, processed, dest)
  from = user.name
  firstname = from.split(" ").first
  case command

    # help: `echo SOMETHING`
    # help:     repeats SOMETHING
    # help:
    when /^echo\s(.+)/i
      respond $1

    # help: `go to sleep`
    # help:   it will sleep the bot for 10 seconds
    # help:
    when /^go\sto\ssleep/i
      unless @questions.keys.include?(from)
        ask("do you want me to take a siesta?", command, from)
      else
        case @questions[from]
          when /yes/i, /yep/i, /sure/i
            @questions.delete(from)
            respond "I'll be sleeping for 10 secs... just for you"
            respond "zZzzzzzZZZZZZzzzzzzz!"
            sleep 10
          when /no/i, /nope/i, /cancel/i
            @questions.delete(from)
            respond "Thanks, I'm happy to be awake"
          else
            respond "I don't understand"
            ask("are you sure do you want me to sleep? (yes or no)", "go to sleep", from)
        end
      end

    # help: ----------------------------------------------
    # help: `run something`
    # help:   It will run the process and report the results when done
    # help:
    when /^run something/i
      respond "Running", dest

      process_to_run = "ruby -v"
      process_to_run = ("cd #{project_folder} &&" + process_to_run) if defined?(project_folder)
      stdout, stderr, status = Open3.capture3(process_to_run)
      if stderr == ""
        if stdout == ""
          respond "#{user.name}: Nothing returned.", dest
        else
          respond "#{user.name}: #{stdout}", dest
        end
      else
        respond "#{user.name}: #{stderr}", dest
      end

    else
      unless processed
        resp = %w{ what huh sorry }.sample
        respond "#{firstname}: #{resp}?"
      end
  end
end

How to access the smart bot

You can access the bot directly on the MASTER CHANNEL, on a secondary channel where the bot is running and directly by opening a private chat with the bot, in this case the conversation will be just between you and the bot.

Some of the commands are available always even when the bot is not listening to you but it is running

For the bot to start listening to you you need to use the "Hi bot" command or one of the aliases

Also you can call any of these commands on demand by using:
