Ale linter for the new norminette (https://github.com/42School/norminette)
Only works with norm version 3.
This linter needs ALE (Asynchronous Linting Engine). Go use that if you're still spending time switching between Vim and the shell.
If you've installed ALE with Vim Plug just copy norminette.vim into ~/.vim/plugged/ale/ale_linters/c/ directory or ~/.config/nvim/plugged/ale/ale_linters/c if you are using Neovim.
If you have installed ALE with another method I am sure you'll be able to find the equivalent path in ~/.vim/
Good luck
