I am amazed, #neovim with #clang #lsp is GREAT, I just learned how to enable inlay hints and found a nice signature help plugin. A big THANK YOU to everyone making this possible. #llvm
Screenshot of neovim editing C code of a new #varnishcache extension showing inlay hints and a signature help function: inlay hints are text snippets (in a different color) added to the code, here showing argument names. The signature help pops up while typing a function call.
