Is there a way to enable code parsing for golang projects in kdevelop. I can build etc. but not hover to see definitions etc. ?

You'd have to write a plugin if no one else did.

In the meantime the CTags plugin that comes with Kate (and can be used in KDevelop nowadays) might be helpful.

There is kdev-go: https://cgit.kde.org/kdev-go.git/
It's somewhat working but needs a bit of love.
