Cinch - The IRC Bot Building Framework
The Cinch project is no longer maintained. No new features will be
added, and no bugs will be fixed. The repository has been archived. If
you wish to continue developing Cinch, please fork the project. I am
not accepting new maintainers for this project.
Description
Cinch is an IRC Bot Building Framework for quickly creating IRC bots in
Ruby with minimal effort. It provides a simple interface based on plugins and
rules. It's as easy as creating a plugin, defining a rule, and watching your
profits flourish.
Cinch will do all of the hard work for you, so you can spend time creating cool
plugins and extensions to wow your internet peers.
For general support, join #cinch channel on Freenode server (irc://irc.freenode.org/cinch) – but
please don't bring any bots.
Installation
RubyGems
You can install the latest Cinch gem using RubyGems
gem install cinch
GitHub
Alternatively you can check out the latest code directly from Github
git clone http://github.com/cinchrb/cinch.git
Example
Your typical Hello, World application in Cinch would go something like this:
require 'cinch'
bot = Cinch::Bot.new do
configure do, c, c.server = "irc.freenode.org"
c.channels = ["#cinch-bots"]
end
on :message, "hello" do, m, m.reply "Hello, #{m.user.nick}"
end
end
bot.start
More examples can be found in the examples directory.
Features
Documentation
Cinch provides a documented API, which is online for your viewing pleasure
here.
Object Oriented
Many IRC bots (and there are, so many) are great, but we see so little of
them take advantage of the awesome Object Oriented Interface which most Ruby
programmers will have become accustomed to and grown to love.
Well, Cinch uses this functionality to its advantage. Rather than having to
pass around a reference to a channel or a user, to another method, which then
passes it to another method (by which time you're confused about what's
going on) -- Cinch provides an OOP interface for even the simpliest of tasks,
making your code simple and easy to comprehend.
Threaded
Unlike a lot of popular IRC frameworks, Cinch is threaded. But wait, don't let
that scare you. It's totally easy to grasp.
Each of Cinch's plugins and handlers are executed in their own personal thread.
This means the main thread can stay focused on what it does best, providing
non-blocking reading and writing to an IRC server. This will prevent your bot
from locking up when one of your plugins starts doing some intense operations.
Damn that's handy.
Plugins
That's right folks, Cinch provides a modular based plugin system. This is a
feature many people have bugged us about for a long time. It's finally here,
and it's as awesome as you had hoped!
This system allows you to create feature packed plugins without interfering with
any of the Cinch internals. Everything in your plugin is self contained, meaning
you can share your favorite plugins among your friends and release a ton of
your own plugins for others to use
Want to see the same Hello, World application in plugin form? Sure you do!
require 'cinch'
class Hello
include Cinch::Plugin
match "hello"
def execute(m)
m.reply "Hello, #{m.user.nick}"
end
end
bot = Cinch::Bot.new do
configure do, c, c.server = "irc.freenode.org"
c.channels = ["#cinch-bots"]
c.plugins.plugins = [Hello]
end
end
bot.start
Note: Plugins take a default prefix of /^!/ which means the actual match is !hello.
More information can be found in the {Cinch::Plugin} documentation.
Numeric Replies
Do you know what IRC code 401 represents? How about 376? or perhaps 502?
Sure you don't (and if you do, you're as geeky as us!). Cinch doesn't expect you
to store the entire IRC RFC code set in your head, and rightfully so!
That's exactly why Cinch has a ton of constants representing these numbers
so you don't have to remember them. We're so nice.
Pretty Output
Ever get fed up of watching those boring, frankly unreadable lines
flicker down your terminal screen whilst your bot is online? Help is
at hand! By default, Cinch will colorize all text it sends to a
terminal, meaning you get some pretty damn awesome readable coloured
text. Cinch also provides a way for your plugins to log custom
messages:
on :message, /hello/ do, m, debug "Someone said hello"
end
Contribute
Love Cinch? Love Ruby? Love helping? Of course you do! If you feel like Cinch
is missing that awesome jaw-dropping feature and you want to be the one to
make this magic happen, you can!
Please note that although we very much appreciate all of your efforts, Cinch
will not accept patches in aid of Ruby 1.8 compatibility. We have no intention
of supporting Ruby versions below 1.9.1.
Fork the project, implement your awesome feature in its own branch, and send
a pull request to one of the Cinch collaborators. We'll be more than happy
to check it out.
