Rubytt is a static Ruby code analyzer, optimized especially for Rails app.
-
The basic ideas comes from rubysonar, but with more help from analysis of db/schema.rb, we may get more accurate types for the code annotation or bug finding.
-
Do some visualizations for the class/db/model.
-
Check the unused variable, this may reported out some bugs, ruby-lint seems can report out these errors, but it's too slow.
-
Check the undefined error [PARTLY FINISHED]
-
Check the type mismatch error [TODO]
-
The project is in experimental status. It's written in OCaml.
