       I use nix-sandbox for managing nix package for other languages.
       One of the functions doesn't work that well for me so I replaced it with something that does
       #+begin_src emacs-lisp :tangle emacsconfig/nix.el
-	(use-package nix-sandbox
-	  :config
-	  (defun nix-executable-find (sandbox executable)
-	    "finds an EXECUTABLE in SANDBOX"
-	    (set (make-local-variable 'exec-path) (nix-exec-path sandbox))
-	    (executable-find executable)))

       Beyond that, there is a helper function that makes it easy to quickly define environments with the required
       packages for a programming language
