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)))

+ "finds an EXECUTABLE in SANDBOX"
+ (set (make-local-variable 'exec-path) (nix-exec-path sandbox))
+ (executable-find executable))
#+end_src
Beyond that, there is a helper function that makes it easy to quickly define environments with the required
packages for a programming language
#+begin_src emacs-lisp :tangle emacsconfig/nix.el
- (defun nix-env-from-packages (name &rest packages)
- "create a nix environment from nix packages. returns the location of the environment"
- (interactive (append
- (list (read-string "Environment name: " nil nil "nameless"))
- (split-string (read-string "Packages: "))))
- (with-temp-buffer
- (insert (format "
- { pkgs ? import %s {}}:
- pkgs.mkShell {
- buildInputs = with pkgs;[
- %s
- ];
- }
- " (or nix-nixpkgs-path "<nixpkgs>") (apply 'concat (intersperse "\n" packages))))
- (write-file (concat temporary-file-directory name "-env/shell.nix"))
- (nix-find-sandbox (concat temporary-file-directory name "-env"))))

Python is a bit weird. It had no intentions at all to do things the way I wanted it to do things with
