This looks great! Every once in a while I decide I want to setup vim like an IDE, and inevitably lose motivation whenever I try to setup autocomplete or linting or language server stuff.
Have you tried using a vim emulator in your IDE? I've been using IdeaVim for IntelliJ for a few months now and it feels like having the best of both worlds. You get the power of vim combined with all the typical IDE features without having to spend hours on configuration.
Tried to get autocomplete to work in Spacemacs for C/C++ using Rtags. While it worked for the project files it could not autocomplete external libraries (such as OpenGL). Since this is why I mostly need autocomplete I could not use Spacemacs as a daily driver even though it had a lot of features that worked really well and was in general a pleasure to use.
Does anyone else here have experience related to what I tried to achieve? Would love to hear similiar experiences.
