Help with clang lsp

[NorseManGef]

Microsoft is shoving copilot in my face on vscode, so I'm moving to nvim. However, I can't seem to get clangd to work right. Firstly, I can't figure out how to get clangd to activate on .inc files (I imagine this is done via lsp.opts but I can't find the documentation, if it exists). Secondly, I'm having issues with clangd not detecting some of my header files, and various other things.

For example: I have my test.cpp file in projectdir/Vector/src folder, and doctest.h in projectdir/common/Include/doctest/doctest.h, test.cpp includes doctest.h with the line #include "doctest/doctest.h", and it compiles just fine, but clangd reports an error. Interestingly, I have another header file in projectdir/common/Include/gravedata.h which is detected by clangd, and it's included via #include "gravedata.h

Despite gravedata.h being detected by the lsp, when I try to call functions under that header file's namespace, clangd claims that namespace, in this case "ian," is an undeclared identifier... it isn't according to vscode, and it compiles and runs just fine.

Sorry for the wordy question, I just have no idea what the problem is, nor how to solve it, and so I'm describing the situation in hopes someone here knows what's causing this.

Edit: I should note that I'm compiling via a makefile in projectdir/Vector/

you need a compile_commands.json, in your case, you need to use bear to generate the file

This didn't solve any of my problems. Bear just generated an empty file, with nothing but [] inside.

you might need to do a clean build, I'm not really sure

check their wiki otherwise https://github.com/rizsotto/Bear/wiki

I should note that meson and cmake have their own ways of generating the file

I got it to work mostly. However, I don't know how to get clangd to pay attention to my .inc files. It seems to read their includes, but that's it. Nvim's parser is also not reading it as c++.

not sure what a .inc file is, but nvim is probably detecting it as a different filetype. Try running :set filetype=cpp while in your .inc file and see if that works

if it does, you'll have to add rules to detect .inc files as cpp files. how exactly to do that I forgot, but :help ftdetect might say something

EDIT: the current recommended way to add filetype detection rules seems to be vim.filetype.add

[NorseManGef]

How would I delcare that in nvf?

we don't currently have nix bindings for the filetype interface, so you'll have to add it as lua code:

{
  vim.luaConfigRC.filetypeRules = ''
    vim.filetype.add({
      extension = {
        inc = "cpp",
      }
    }) 
  '';
}
