How do I create my own ${pkgs.mypkg} based on a shell script?

Without flakes… the most practical thing to do is to write some shell.nix file, and invoke nix-shell with that.

It’s possible to add myscript to nixpkgs such that literally nix-shell -p myscript, you’d define a nixpkgs overly with myscript. c.f. Overlays in the nixpkgs manual: Nixpkgs Manual

Ah, you beat me to it. I have just finished writing How do I run nix-shell with a package from my own new channel?, one question per post and all. And I also found overlays to work.

Yeah, flakes are on my todo list. The learning curve for NixOS is steep even for a professional software developer.

Thank you for your answers.
