First pull latest develop and do a bin/doom update
I did this wrong the first time, but the doom-emacs author is here to help. See his solution below but also add this one line
(setq-hook! 'scala-mode-hook +lsp-company-backend 'company-capf)
type /**
above a class or whatever which will autocomplete a blank template, then use M-x
and
type company-capf
you should get a popup for scaladoc completion. I have to be in insert (not visual) mode for this to work.
Definitely helps! I'll go update my files.
