POE::Component::DebugShell - Component to allow interactive peeking into a running POE application
use POE::Component::DebugShell; POE::Component::DebugShell->spawn();
This component allows for interactive peeking into a running POE application.
spawn() creates a ReadLine enabled shell equipped with various debug commands. The following commands are available.
debug> show_sessions * 3 [ session 3 (POE::Component::DebugShell controller) ] * 2 [ session 2 (PIE, PIE2) ]

Display various statistics for a given session. Provide one session id as a parameter.
debug> list_aliases 2 Alias list for session 2 * PIE * PIE2
List aliases for a given session id. Provide one session id as a parameter.
debug> queue_dump Event Queue: * ID: 738 - Index: 0 Priority: 1078459009.06715 Event: _sigchld_poll * ID: 704 - Index: 1 Priority: 1078459012.42691 Event: ping

_raw_commands returns a hash reference. The keys of this hash are the command names. The values are a hash of data about the command. This hash contains the following data:
Short help text
Long help text
Code reference for the command. This command requires that a hash be passed to it containing an
apiparameter, which is a
POE::API::Peekobject, and an
argsparameter, which is an array reference of arguments (think
