I have written several literate programs in Ruby using noweb and I have enjoyed the experience except for debugging. The lack of a line directive in Ruby makes debugging quite challenging.
To make writing noweb Literate programs more pleasant I have submitted a patch to Ruby to add the missing line directive functionality.
Unfortunately I have not had any luck in getting this patch accepted into a Ruby release.
Below are the pull request on GitHub and the feature request on ruby-lang.
