Yep, Kythe is the open-source version of grok. It's awesome, and the srclib team is in touch with the Kythe team at Google to build on top of their analysis lib

Yep, Kythe is the open-source version of grok. It's awesome, and the srclib team is in touch with the Kythe team at Google to build on top of their analysis libs (for C++ and Java). Long term vision is to get rid of the "my editor X doesn't support language Y" problem as well as build a lot of other multi-language analysis tools on top of it. Shameless plug: if you care about developer productivity, join us!
