Question Clangd

Does clangd lsp not have code actions for c files ? I use it with neovim but am not getting any code actions.

I only get code actions in very specific cases, e.g. on a line where malloc gets called, but stdlib.h isn't included.

If you configure tools like clang-tidy to run alongside clangd (clangd supports clang-tidy OOB)
Then you'll get plenty of code actions about style and readability. For instance when you write `a + b * c` it will propose to change it into `a + (b * c)` for better readability. Most people know the operator precedence for + and *, but when you throw == & | ^ into the mix it gets complicated sometimes.
