I was looking for something like this the other day but then ended up just using RubyVM::AbstractSyntaxTree.parse_file and then rolled my own visitor on top of the AST. It's cool what they can do here but I think any language that exposes its AST is amenable to this kind of analysis, you just have to write some code to do it. The main bottleneck in my experience is just being familiar with the AST structure and how it maps to source syntax. It's cool that they have abstracted a lot of the commonality among several languages, definitely gonna look into this next time I need semantic code search.
