Hello Oleg,
sorry for the late reply, I was on the road.
Here is a way of doing it :
---8<---
pdef = Ruote.process_definition do
sequence do
set :field => 'f', :val => { 'name' => 'toto', 'address' => %w[ KL Asia ]}
echo 'a${f:missing}'
echo 'b${f:f.name}'
echo 'c${f:f.address.1}'
end
end
--->8---
and another :
http://github.com/jmettraux/ruote/blob/ruote2.1/test/functional/ft_10_dollar.rb#L108-123
This ft_10_dollar.rb test file should contain all the possibilities.
By the way, I've been working on a solution to
http://github.com/jmettraux/ruote/issues#issue/11
Stay tuned.
Best regards,
