Describe the bug

Clangd generates endless invalid AST errors when attached to a buffer that contains C++ code but does not have a typical C++ extension.

clangd version 15.0.7

Steps to Reproduce

Install clangd LSP client
Open a file like "test.cuh" or "test.inl" and write some C++ code
IDK, close and reopen it
Move cursor around.

Expected behavior

No repeated errors.

Looks like a bug in clangd language server improperly handling document highlighting requests. This is not something AstroNvim can fix or handle at all, but you can disable the automatic document highlighting in your user configuration for the clangd server until they fix their bugs. Something like this is an example user/init.lua file:

return {
  lsp = {
    config = {
      clangd = {
        on_attach = function(client, bufnr)
          local cmds_found, cmds =
            pcall(vim.api.nvim_get_autocmds, { group = "lsp_document_highlight", buffer = bufnr })
          if cmds_found then vim.tbl_map(function(cmd) vim.api.nvim_del_autocmd(cmd.id) end, cmds) end
        end,
      },
    },
  },
}

Or if you have a split up user configuration, you can just put this in the file user/lsp/config/clangd.lua:

return {
  on_attach = function(client, bufnr)
    local cmds_found, cmds = pcall(vim.api.nvim_get_autocmds, { group = "lsp_document_highlight", buffer = bufnr })
    if cmds_found then vim.tbl_map(function(cmd) vim.api.nvim_del_autocmd(cmd.id) end, cmds) end
  end,
}
