Hi @giuse88

I will try to setup a regular expression parser for Scala using the information available in:
https://leonard.io/blog/2013/04/editing-scala-with-vim/
https://github.com/luben/sctags

Could you please provide some small Scala example code files that would generate tags for all the types mentioned in the above links?

See universal-ctags/ctags-xparsers#2

OpenGrok also uses some patterns to detect scala
https://github.com/OpenGrok/OpenGrok/blob/master/src/org/opensolaris/opengrok/analysis/Ctags.java#L120

(and go and clojure and haskell)

[masatake]

Can we use it in GPL v2 or later?

Opengrok is cddl so ... i don't know, but I'd hope so ...
