This PR add two small files to make it more friendly for editors (like Neovim)
.editorconfig
- Sets basic indentation and style for this repository.clangd
- Helps to discover local and third-party header files viacompile_commands.json
Without (1), my default 4 spaces makes it weird. This config will keep the spaces consistent in the editor as per the existing code in this repository.
Without (2), my editor (Neovim) failing to find the non-standard header files.
Both (1) and (2) are inspired from Neovim repository itself and also looked pretty standard for C++ projects.
I kept the configs to bare minimum. Happy to add additional flags
--std=c++20
in.clangd
if needed to enforce C++20 standard for editor's LSP client for this repository as mentioned in the CMU Database course https://15445.courses.cs.cmu.edu/fall2025/faq.html#q5
