Is it possible to use a specific version of clangd?

[Kraust]

I am currently using nixos-unstable which is bringing in llvm 19 (and by extension clangd 19.1.7) but I want to format code as if I'm using llvm 18 as my CI/CD pipeline has clang-format 18.1.8 installed. I assume I can do this with an overlay of some kind, but not exactly sure how.

Depending on how you manage the clangd LSP you can set lsp.servers.clangd.package or plugins.lsp.servers.clangd.package
