I’m the only one using Nix in a project. For now I just created shell.nix and other nix file inside the project folder but I didn’t include these file in the git repo. But I want to keep those files in repo to keep the history and other stuffs. What is the recommend way to do this? I thought in create a new repo to those files and create a symbolic link to them in my project. Is it a good idea?
A contrib/ in the project root is a common place to store useful files that may not necessarily be maintained. Perhaps your team could compromise with that? A comment header stating the file’s purpose would be apt, too (and may eventually move more team members to try Nix out).
If you don’t want to include them in the ‘upstream’ git repo, but want to keep them versioned in your ‘own’ tree, there is a couple of options as well:
- git-along integrates with git tightly. TBQH I don’t quite understand where the files actually go :).
-
shellbit puts them all under a top-level nix expression, so you can load them right into nix-shell with
-A. An example repo is at nixels. - nix-environments also just has a top-level nix expression without any particular tooling.
- nix-shell-git just puts shell.nix files in a tree. An example repo is at nix-shells
Sorry, I don’t know, I like to enter my nix-shells explicitly 
I use direnv to avoid garbage-collector
ah that is kindof neat indeed, I didn’t realize nix-direnv took care of that (GitHub - nix-community/nix-direnv: A fast, persistent use_nix/use_flake implementation for direnv [maintainer=@Mic92 / @bbenne10]). OTOH it’s kind of nice that I can garbage-collect things that belong to projects I’m not actively working on
