Hello List,
I've just pushed a set of changes that simplify local participants. For
instance, you can rewrite
---8<---
class MyParticipant
include Ruote::LocalParticipant
def consume(workitem)
workitem.fields['message'] = 'this is my participant'
reply_to_engine(workitem)
end
end
--->8---
as
---8<---
class MyParticipant
include Ruote::LocalParticipant
def on_workitem
workitem.fields['message'] = 'this is my participant'
reply
end
end
--->8---
The 'workitem' becomes implicit (ie, an instance method).
The other methods (on_cancel, on_reply, accept?, dont_thread?) have been
simplified likewise, with helper methods like fei, fexp, workitem, flavour,
lookup_variable popping up.
For more information, please refresh

I've updated with [upcoming] ruote 2.2.1 information.
I prefer the on_x scheme, it clearly shows the "hookesque" nature of the
participants.
Feel free to fire questions and suggestions, and/or to point me at typos and
errors...
It should be 100% backward compatible, if not, please shout.
Best regards,
