libCat VS clangd

That's awesome! I'm working on something that sounds similar. https://github.com/cons-cat/libcat

I'd love to see your work if you're willing to share it here!

It's worse in the standard library than it has to be. When I refactored my traits to minimize template instantiations and lean on concepts as much as possible, I measured over 30% improvement to clean build compile times. It's not possible for the standard to do this, because it would subtly change the API. For instance, you can't instantiate or take the address of a concept, but you can for a type-trait class. No reason you'd want to do that, but you can, so they can't "break" the standard library by optimizing this.

This doesn't have to be true. Over the past year I've made progress towards demonstrating how even non-freestanding C++ can be written without any C or C++ standard library headers or DLLs (with large benefits). There are a few names which the compilers require to be in the std:: namespace, though, but they're very special features like source_location and construct_at with semantics that can't be expressed otherwise.

It isn't that hard to put a predicate into a type. We have lambdas in an unevaluated context, CTAD, and templated type aliases. https://github.com/Cons-Cat/libCat/blob/main/src/libraries/scaredy/cat/scaredy https://github.com/Cons-Cat/libCat/blob/main/src/global_includes.hpp#L70 https://github.com/Cons-Cat/libCat/blob/main/src/libraries/linux/cat/linux#L289 You do it like this.

I use clang-tidy. These are my current linting rules.

Come to the light side: VSCodium with clangd

More Details here: https://clangd.llvm.org/

If you use the clangd LSP: https://github.com/clangd/clangd/issues

Overall I think it’s pretty good. Though I’ve found a nasty clangd bug might push me back to YCM. Though. I don’t recall this being a issue in my previous vim setup.

That's why most people don't even try to do that, they use clangd instead.

- set up neovim with "intellisense" (language server + code completion). I would suggest https://github.com/VonHeikemen/lsp-zero.nvim with the "recommended" preset to start with. From there,when you edit a C++ file for the first time, I'll ask if you want to add a language server for it: just say "YES". This will install `clangd` (https://clangd.llvm.org/) automagically.

LSP is just a communication protocol. You need two parts: an LSP client and a server. What Neovim includes is the client, the part that integrates with the editor. You will still need a separate server for each language, e.g. pylsp for Python or clangd for C. These are separate programs which exist outside of Neovim, they are editor-agnostic and can be used with any other LSP client as well.

clangd as lsp server
