How do I tell clangd that I am writing C++20 code?
How do I tell clangd that I am writing C++20 code?
I use Helix Editor and by default it uses clangd as LSP server.
But when I use "newer" C++20 features I get warning messages in the editor that they are only available in "later" C++ versions or I get straight up error messages.
So how do I tell clangd that I am writing C++20 code? I am guessing passing an argument (-std=c++20) or creating a "project properties" file...
This is the Helix Editor configuration file, languages.toml:
[[language]]
name = "cpp"
language-server = { command = "clangd", args = [] }
auto-format = true
Please let me know the right way to do it.

If you use meson or cmake, you can generate a compile_commands.json which you can link from the build dir into your source dir. If not you cam create a local config file for clangd https://stackoverflow.com/questions/73758291/is-there-a-way-to-specify-the-c-standard-of-clangd-without-recompiling-it
This,
.clangd, file in the root of the project directory worked:CompileFlags: Add: [-std=c++20]Thank you!
