如何为clang的C++20特性正确设置ccls？

Question

I am currently setting up nvim as my main editor and try to get autocompletion to work properly with C++20. The cpp code below compiles fine with eg g++-11 -std=c++20 or even with clang (only right ranges library path need to be linked) but the ccls server throws an error on the range-based for loop.

I configured the .ccls like that:

the -ccc-install-dir just puts the new c++20 std lib in to locate ranges. And finally my coc-settings.json looks like this:

And I can't figure out why the completion doesn't work for features that clearly compile and eg in Xcode don't even throw an error but with ccls it doesn't work.

Answer 1

give a try to roshnivim , it works out of the box. Everyone has theirs own taste of config and mappings so, you can change it here .
