Summer

Summer is an IRC Bot "framework" "inspired" by http://github.com/RISCFuture/autumn. Its goal is to be tiny.

Installation

The project is currently in "preview" state 'cause that's all the rage nowadays. No there's no invites, BUT everybody gets access to it. Sorry to inform you that you'll have to clone it and then run rake install if you want to use it.

Usage

To use summer, create a file like this:

require 'rubygems'
require 'summer'

class Bot < Summer::Connection

end

Bot.new("localhost")

Running it will make your bot attempt to connect to the server on localhost. For those of you who do not have an IRC server running locally, I would suggest trying irc.freenode.net instead.

Configuration

In the same directory create a directory called config and in that put summer.yml which can have the following keys:

• server: The IRC server url the bot will connect to. Can also be passed in to the initializer as the first argument.
• use_ssl: true or false defaults to false. If an IRC server requires SSL, it will establish the connection
• nick: The nickname of the bot.
• server_password: Password to authenticate with a server, if the irc server requires it.
• nickserv_password: Password to send to nickserv after connection but before joining any channels
• channel: A channel to join on startup.
• channels: Channels to join on startup. e.g. ['RubyOnRails', 'ruby']
• auto_rejoin: Set this to true if you want the bot to re-join any channel it's kicked from.

API

The following are some methods you can define in your class which inherits from Summer::Connection.

Handling raw messages

If you wish to handle raw messages that come into your bot you can define a handle_xxx method for that where xxx is the three-digit representation of the raw you wish to handle.

Using with Slack

Slack is becoming more and more popular; though many of us still like our IRC & IRC bots. The good thing is Slack offers an IRC and XMPP gateway!

Setting up summer to connect to slack is quite simple:

1. Configure your slack channel to use IRC

Your Slack team's owner will first need to enable team-wide gateway access at my-channel.slack.com/admin/settings, in the Gateways section under the Permissions tab. It must be an owner, not just an admin.

2. Obtain credentials for your bot to access the slack IRC channel

Once the gateway is enabled, your bot (and other team members) can get connection instructions and their unique gateway password at: my-channel.slack.com/account/gateways.

Name	Value
Host	my-channel.irc.slack.com
User	my-nick
Pass	my-pass

3. Configure summer to use the server password & ssl

In your config/summer.yml file, add your credentials:

nick:              ENV['NICK']
use_ssl:           true
server_password:   ENV['SERVER_PASS']
channels:          ['general', 'random']

Then start your bot per usual:

Bot.new(ENV['IRC_SERVER'])
