Is there exists a TAGS solution (ripper-tags in ruby) which support jump to definition use tags table?

I use ripper-tags to generate a TAGS for me to use it with emacs.

there is a bash script, rbtagger, even make update TAGS process automatically.

Though there is more robust solution, e.g. robe, but TAGS always can serve as fallback solution when robe not working.

So, is there exists a tags generate tool for crystal i can used for jump to definition?
