  • How to combine rtags and vertico
    4 projects | /r/emacs | 7 Apr 2023
    I decided to install cmake-ide. It seems that rtags came along with the former. Fine, but I also decided to use the vertico package. It also seems that rtags has a support for Helm, but from what I understand, Helm and and Vertico fall under the same category of packages and therefore I can only have one of them.
  • Modern alternate to ctags/etags?

    An alternative to LSP is rtags. I found this is often a lot faster than LSP, with any server.
