What has changed in 2.2?

Getting rid of CP1252 in favour of UTF-8

In versions before 2.2, when using the irc encoding (the default), Cakewalk would use CP1252 for outgoing messages, only falling back to UTF-8 if a message wouldn’t fit into CP1252. This is a so called hybrid encoding, which is used by X-Chat and the like.

This encoding, however, is based on the state of 10 years ago, where the most popular IRC clients, such as mIRC, weren’t capable of handling UTF-8. Nowadays, there are more clients that support UTF-8 than there are clients that can deal with this hybrid encoding, or CP1252 itself. That’s why, from now on, we will always use UTF-8.

If you depend on outgoing messages being encoded in CP1252, please see encodings on how to change the encoding.

Color stripping

The new method Cakewalk::Utilities::String.strip_colors Cakewalk::Formatting.unformat allows removal of mIRC color codes from messages.

Additionally, a new match option called strip_colors makes it possible to automatically and temporarily strip color codes before attempting to match a message.

Per group hooks

A new option group for hooks allows registering hooks for specific groups.

New aliases

Due to some unfortunate naming mistakes in Cakewalk 2.0, Cakewalk 2.1 adds several aliases. All of the new aliases deprecate the original method names, which will be removed in Cakewalk 3.0.

Added support for SASL

Cakewalk now supports authenticating to services via SASL. For more information check Cakewalk::SASL.

Added support for DCC SEND

Support for sending and receiving files via DCC has been added to Cakewalk. Check Cakewalk::DCC for more information.

Added a fair scheduler for outgoing messages

Cakewalk always provided sophisticated throttling to avoid getting kicked due to excess flood. One major flaw, however, was that it used a single FIFO for all messages, thus preferring early message targets and penalizing later ones.

Now Cakewalk uses a round-robin approach, having one queue per message target (channels and users) and one for generic commands.

Added required plugin options

Plugins can now require specific options to be set. If any of those options are not set, the plugin will automatically refuse being loaded.

This is useful for example for plugins that require API keys to interact with web services.

The new attribute is called required_options.

Example:

class MyPlugin
  include Cakewalk::Plugin

  set :required_options, [:foo, :bar]
  # ...
end

# ...

bot.configure do |c|
  c.plugins.plugins = [MyPlugin]
  c.plugins.options[MyPlugin] = {:foo => 1}
end

# The plugin won't load because the option :bar is not set.
# Instead it will print a warning.

Added support for colors/formatting

A new module and helper for adding colors and formatting to messages has been added. See the module’s documentation for more information on usage.

Added support for network discovery

Cakewalk now tries to detect the network it connects to, including the running IRCd. For most parts this is only interesting internally, but if you’re writing advanced plugins that hook directly into IRC and needs to be aware of available features/quirks, check out Cakewalk::IRC#network and Cakewalk::Network.

Reworked logging facilities

The logging API has been drastically improved. Check the logging documentation for more information.

Added match groups

A new option for matchers, :group, allows grouping multiple matchers to a group. What’s special is that in any group, only the first matching handler will be executed.

Example:

class Foo
  include Cakewalk::Plugin

  match /foo (\d+)/, group: :blegh, method: :foo1
  match /foo (.+)/,  group: :blegh, method: :foo2
  match /foo .+/,                   method: :foo3
  def foo1(m, arg)
    m.reply "foo1"
  end

  def foo2(m, arg)
    m.reply "foo2"
  end

  def foo3(m)
    m.reply "foo3"
  end
end
# 02:05:39       dominikh │ !foo 123
# 02:05:40          cakewalk │ foo1
# 02:05:40          cakewalk │ foo3

# 02:05:43       dominikh │ !foo bar
# 02:05:44          cakewalk │ foo2
# 02:05:44          cakewalk │ foo3

Added match options overwriting plugin options

Matchers now have their own :prefix, :suffix and :react_on options which overwrite plugin options for single matchers.

Added support for actions (/me)

A new event, <code>:action</code> has been added and can be used for matching actions as follows:

match "kicks the bot", react_on: :action
def execute(m)
  m.reply "Ouch!"
end

API improvements

Helper changes

The helper methods User() and Channel() have been extracted from Cakewalk::Bot and moved to their own module which can be reused in various places.

Added a Target class

Since Cakewalk::Channel and Cakewalk::User share one common interface for sending messages, it only makes sense to have a common base class. This new class takes care of sending messages and removes this responsibility from Cakewalk::Channel, Cakewalk::User and Cakewalk::Bot

Cakewalk::Constants

All constants for IRC numeric replies (RPL_* and ERR_*) have been moved from Cakewalk to Cakewalk::Constants

New methods

Cakewalk::Bot

Cakewalk::Channel

Cakewalk::Helpers

Logging shortcuts

Cakewalk::IRC

Cakewalk::Message

Cakewalk::Plugin

Cakewalk::User

Handlers

Internally, Cakewalk uses Handlers for listening to and matching events. In previous versions, this was hidden from the user, but now they’re part of the public API, providing valuable information and the chance to unregister handlers alltogether.

Cakewalk::Bot#on now returns the created handler and Cakewalk::Plugin#handlers allows getting a plugin’s registered handlers.

Removed/Renamed methods

The following methods have been removed:

Removed method Replacement
Cakewalk::Bot#halt next or break (Ruby keywords)
Cakewalk::Bot#raw Cakewalk::IRC#send
Cakewalk::Bot#msg Cakewalk::Target#msg
Cakewalk::Bot#notice Cakewalk::Target#notice
Cakewalk::Bot#safe_msg Cakewalk::Target#safe_msg
Cakewalk::Bot#safe_notice Cakewalk::Target#safe_notice
Cakewalk::Bot#action Cakewalk::Target#action
Cakewalk::Bot#safe_action Cakewalk::Target#safe_action
Cakewalk::Bot#dispatch Cakewalk::HandlerList#dispatch
Cakewalk::Bot#register_plugins Cakewalk::PluginList#register_plugins
Cakewalk::Bot#register_plugin Cakewalk::PluginList#register_plugin
Cakewalk::Bot#logger Cakewalk::Bot#loggers
Cakewalk::Bot#logger=  
Cakewalk::Bot#debug Cakewalk::LoggerList#debug
Cakewalk::IRC#message Cakewalk::IRC#send
Cakewalk::Logger::Logger#log_exception Cakewalk::Logger#exception
Class methods in Plugin to set options A new set method as well as attribute setters

The Plugin class

The Plugin class has been drastically improved to look and behave more like a proper Ruby class instead of being some abstract black box.

All attributes of a plugin (name, help message, matchers, …) are being made available via attribute getters and setters. Furthermore, it is possible to access a Plugin instance’s registered handlers and timers, as well as unregister plugins.

For a complete overview of available attributes and methods, see Cakewalk::Plugin and Cakewalk::Plugin::ClassMethods.

Plugin options

The aforementioned changes also affect the way plugin options are being set: Plugin options aren’t set with DSL-like methods anymore but instead are made available via a set method or alternatively plain attribute setters.

See the migration guide for more information.

Channel/Target/User implement Comparable

Cakewalk::Target and thus Cakewalk::Channel and Cakewalk::User now implement the Comparable interface, which makes them sortable by all usual Ruby means.

Renamed *Manager to *List

Cakewalk::ChannelManager and Cakewalk::UserManager have been renamed to Cakewalk::ChannelList and Cakewalk::UserList respectively.

Added support for broken IRC networks

Special support for the following flawed IRC networks has been added:

  • JustinTV
  • NGameTV
  • IRCnet

Dynamic timers

It is now possible to create new timers from any method/handler. It is also possible to stop existing timers or restart them.

The easiest way of creating new timers is by using the Timer helper method, even though it is also possible, albeit more complex, to create instances of Cakewalk::Timer directly.

Example:

match /remind me in (\d+) seconds/
def execute(m, seconds)
  Timer(seconds.to_i, shots: 1) do
    m.reply "This is your reminder.", true
  end
end

For more information on timers, see the Timer documentation.

New options

New events

What has changed in 1.1?

  1. New events
  2. New methods
  3. New options
  4. Improved logger x. Deprecated methods

New events

Additionally, plugins are now able to send their own events by using Cakewalk::Bot#dispatch.

New methods

Cakewalk::User#last_nick

Stores the last nick of a user. This can for example be used in on :nick to compare a user’s old nick against the new one.
