Hmm yeah i think an actual array returned from the stack option would
make it easier to code around, especially when things start getting
crowded:
engine.register_participant 'summary' do |workitem|
puts '... summary :'
puts "#{workitem.to_h.inspect}"
end
engine.register_participant '.+' do |workitem|
workitem.fields['result'] = "#{workitem.participant_name} : #{rand}"
end
pdef = Ruote.process_definition :name => 'test' do
sequence do
concurrence :merge_type => :isolate do
alpha
bravo
charly
end
summary
concurrence :merge_type => :isolate do
delta
echo
foxtrot
end
summary
end
end
prints:
... summary :
{"participant_name"=>"summary", "fields"=>{"0"=>{"result"=>"alpha :
0.769486208591124", "__result__"=>"alpha : 0.769486208591124"},

..an array here would definitely be easier on the eyes. i haven't
downloaded the new version and tried stack out, but I'll let you know
when I do.
