Hey John,
Actually shortly after I posted, i started messing with Ruote Kit
in rails and am making adjustments with that. But in the meantime:
================================================
def generate_process_definition
tasks_array =%w[ task0 task1 taskC ]
p tasks_array
return tasks_array
end
-------------------------------------------
.. yields via irb:
["task0", "task1", "taskC"]
=> ["task0", "task1", "taskC"]
============================================
And this works too:
==================================================
def generate_process_definition
input_files = %w[ test1 test2 test3 ]
pdef = Ruote.process_definition do
sequence do
cleanup
end
end
return pdef
end
------------------------------------------------
yields (as expected):
["define", {}, [["sequence", {}, [["cleanup", {}, []]]]]]
=============================================================
BUT when i was calling it in a rails activerecord, 'self' appears to
be overwritten in the Dsl. so I had to reassign any of those methods
to a variable..
this hangs after printing out the array:
=================================================
def generate_process_definition
puts self.input_files # <== shows array of files
pdef = Ruote.process_definition do
sequence do
concurrence do
input_files.each do |i|
cleanup
end
end
cleanup
end
end
return pdef
end
-----------------------------------------
..yields:
>> s.generate_process_definition
dasdasd
(hang)
========================================================
BUT this worked:
==============================================
def generate_process_definition
ia = self.input_files
pdef = Ruote.process_definition do
sequence do
concurrence do
puts self.class
ia.each do |i|
cleanup
end
end
cleanup
end
end
return pdef
end
-----------------------------------------------
yields..
>> s.generate_process_definition
Ruote::RubyDsl::BranchContext
=> ["define", {}, [["sequence", {}, [["concurrence", {}, [["cleanup",
{}, []]]], ["cleanup", {}, []]]]]]
=====================================================================================================
