Bot::Cobalt::Core - Bot::Cobalt core and event syndicator


This module is the core of Bot::Cobalt, tying an event syndicator (via POE::Component::Syndicator and Object::Pluggable) into a logger instance, configuration manager, and other useful tools.

Core is a singleton; within a running Cobalt instance, you can always retrieve the Core via the instance method:

  require Bot::Cobalt::Core;
  my $core = Bot::Cobalt::Core->instance;

You can also query to find out if Core has been properly instanced:

  if ( Bot::Cobalt::Core->has_instance ) {


If you 'use Bot::Cobalt;' you can also access the Core singleton instance via the core() exported sugar:

  use Bot::Cobalt;
  core->log->info("I'm here now!")

See Bot::Cobalt::Core::Sugar for details.

Public methods are documented in "Core methods" in Bot::Cobalt::Manual::Plugins and the classes & roles listed below.

Custom frontends

It's trivially possible to write custom frontends to spawn a Cobalt instance; Bot::Cobalt::Core just needs to be initialized with a valid configuration object and spawned via POE::Kernel's run() method.

A configuration object is an instanced Bot::Cobalt::Conf:

  my $conf_obj = Bot::Cobalt::Conf->new(
    etc => $path_to_etc_dir,

Which is passed to Bot::Cobalt::Core before the POE kernel is started:

  ## Instance a Bot::Cobalt::Core singleton
  ## Further instance() calls will return the singleton
  my $core = Bot::Cobalt::Core->instance(
    cfg => $conf_obj,
    var => $path_to_var_dir,

    ## See perldoc Bot::Cobalt::Logger regarding log levels:
    loglevel => $loglevel,

    ## Debug levels:
    debug => $debug,

    ## Indicate whether or not we're a daemon
    ## (Changes behavior of logging and signals)
    detached => $detached,

Frontends have to worry about daemonization on their own.
