You can inline the script within nix and get them all in one file (but that implies buy-in on nix, or maintaining 2 copies of the script). At the risk of overstepping (it sounds like you might be a little interested) here are a few links in to some basics just-in-case. For context, I extracted my bashrc into its own repo, and it in turn sources bash libraries for my shell history and git status plugins. It's also leaning on some libraries that are pulled in through those two. (To be clear, this is just a general example of the flake pattern with a separate lockfile. I can find or synthesize something with the inline script pattern if you ask.) - Source statements: https://github.com/abathur/bashrc.nix/blob/e7c437578e2a623f44a721ac7860f054745155ce/bashrc#L28-L31 https://github.com/abathur/bashrc.nix/blob/e7c437578e2a623f4... - Nix expression responsible for resolving and ~linking these two dependencies in to the final script: https://github.com/abathur/bashrc.nix/blob/e7c437578e2a623f44a721ac7860f054745155ce/bashrc.nix#L12-L25 https://github.com/abathur/bashrc.nix/blob/e7c437578e2a623f4... - Flake inputs for the two dependencies. Note that these can be specified as just the repo or a branch and updated by updating the lock through Nix, or they can be ~pinned to a specific rev: https://github.com/abathur/bashrc.nix/blob/e7c437578e2a623f44a721ac7860f054745155ce/flake.nix#L11-L22 https://github.com/abathur/bashrc.nix/blob/e7c437578e2a623f4... - A gist with examples of the entire chain of scripts that get resolved together here: https://gist.github.com/abathur/09f06f1f34b003376017d7a5c031a13b https://gist.github.com/abathur/09f06f1f34b003376017d7a5c031... These all get handled separately, so they can technically have divergent implementations of the same external command (for example, one library could depend on libressl and one could depend on openssl--and each resolved library would independently point to the correct one.
