Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

first I must apologize for being newbie to Perl and asking more general question.
I'd like to implement event/action processing engine in Perl and don't know whether some similar projects already exists where I could learn/expand from...

I'd like to have :
- simple config file (maybe xml format) with criteria (expressed as expression of logically tied events)
- responding (possibly complex) actions when criteria is met...

It should be pretty straighforward to add/edit/delete actions from config file and also process the rules from file...

Any project or code snippet to get me starting ?

Thanks in advance for your wisdom,

regards,

Rob.

for instance : if (motion_detected and (night or lowlightlevel) then (turnlight on and beep))

    In a way, such a framework is already written for you in Workflow, but the configuration language is XML.

    In another way, you might fare better with using Prolog or AI::Prolog (or better the Perl bindings to SWI Prolog), depending on how you structure and write your criteria and whether you want a procedural logic flow like a sequence of if statements (first matched hits) or whether you want to find all matching clauses.

    POE provides an event framework that you also might want to look into building on top of.
