Where is the syntax error in this Ruby snippet?
Hair pulling ...
Prawn::Document.generate(@targetfile) do |pdf|
pdf.bounding_box ([80, 510] , :width => 400) do
pdf.text("hello")
end
end
gives a strong syntax error , unexpected ',' expecting ')' for the 'comma' just before : width => 400
I tried this with both Ruby 1.9.3 and 2.1 - both give the same error. The only thing I changed is that I updated the version of shrimp from 1.0 to 2.0 - according to the guide using shrimp, it should still be fine.

agree with andrew's answer above. When using a function call in ruby, you can either have a space without parentheses, or parentheses rather than a space, but not both. So:
pdf.bounding_box([80, 510] , :width => 400)
ok
pdf.bounding_box [80, 510] , :width => 400
also ok
But you cannot do space and parentheses. Now in your case, since you want to bind the result of this to a do / end block, you will have to use parentheses, so option 1 is the only way to go.
