How can I modify the clangd.lua to make it support C++ 20?

Hi, I have some problems with modifying the clangd.lua to make it support C++ 20.

How can I modify this?

afaik clangd doesn't support setting driver options thru command line options atm. But u can create a user or project config (see clangd:Configuration#files) and fill in the following content to make it work:

CompileFlags:
  Add: [-std=c++20] # or -std=gnu++20

Do note that support for c++20 by many open-source LSP vendors, including clangd, is still in the alpha stage, and many features that require compiler support have not (yet) been implemented. You may encounter a bunch of errors and it's expected, see my reply here.
