> For example, I have a lot of Jetbrains IDEs installed for various languages, but I don't want to pollute my global environment with tools, especially command line tools that pollute the PATH. Let's say I want to use Jetbrains Rider. I can easily start a shell with the dotnet SDK with `nix-shell -p dotnet`, then start Rider under that shell. This is OK, but it feels wrong to me. It feels weird that launching Rider outside of nix-shell won't ever work, yet it's installed globally. And yet, I also kind of want it to be globally installed... I use nix-buffer[0], which lets Emacs pick up the environment automatically when I open any file in the project. And as long as you only use setq-local it'll stay scoped to those files, "normal" files still open in the regular user environment. It's even seamless to keep files from multiple such projects open at once. [0]: https://github.com/shlevy/nix-buffer https://github.com/shlevy/nix-buffer
