NAME
Bot::Net::Mixin - build complex objects my mixing components
SYNOPSIS
# Define your own mixin
use strict;
use warnings;
package MyBotNet::Mixin::Bot::Counter;
use base qw/ Bot::Net::Mixin /;
use Bot::Net::Mixin::Bot::Command;
# Add a counter command to a bot
sub setup {
my $self = shift;
my $brain = shift;
$brain->remember( [ 'counter' ] => 0 );
}
on bot command next => run {
my $event = get ARG0;
my $counter = recall 'counter' + 1;
remember counter => $counter;
yield reply_to_sender => $event => $counter;
};
1;
DESCRIPTION
This is the base class for all Bot::Net mixins. It basically provides for a way of cataloging which mixins a class has added, tools for mixin setup, and magic for pulling mixin stuff into the importing package.
METHODS
import
Exports anything the module lists in it's @EXPORT
variable, if such a method exists.
default_configuration PACKAGE
This is used to build the default configuration file when creating a new bot or server using the botnet script and used by Bot::Net::Test to help build the base test bot or test server configuration.
A mixin should override this to return a reference to a hash containing any default values it recommends or requires for bot configuration. It will be called as a class level method and passed the name of the PACKAGE
that the mixin is being used to build:
MyBotNet::Mixin::Bot::PasteBot->default_configuration('MyBotNet::Bot::FancyPaster');
MIXIN IMPLEMENTATIONS
A mixin may implement whatever POE states it wishes to using the POE::Declarative interface. Those states will be imported into the calling package.
If a mixin needs to perform any setup prior to POE::Kernel startup, it may be do so by implementing a setup
method. It will be passed two arguments, the $self
variable for the class stored with the session and the Data::Remember brain object that will be stored in the heap of the session being created.
sub setup {
my $self = shift;
my $brain = shift;
# Using the internal brain interface of Data::Remember, make sure to
# be careful to use only array-based ques!
$brain->remember( [ 'foo' ] => 'bar' );
}
In general, however, your mixins can probably get away with performing initial setup in the _start
state.
