I’ve published a small project of mine, which I called mudenv
It’s a library built atop labs’ lib, which provides the basics to make development environments with nix-shell. For now, it looks a lot like an undocumented and dumbed down numtide/devshell (especially because right now it relies entirely on nixpkgs for any derivation, including writing text files), but the plan is to use as much from aux-labs as possible. The repo’s shell.nix acts as an example (for now), it provides a rust toolchain from fenix and allows compiling the create openssl-sys from source and running binaries that dynamically link against openssl.
I’m hoping to get equivalents of nixpkgs’ writeText and buildEnv in aux labs (I’ve opened an issue) so that nixpkgs is not needed by default.
Feel free to hack around ! I’m pretty sure there’s a ton of buggy edge cases (notably I haven’t tested it with flakes and nix develop and I’m pretty sure it doesn’t work quite right).
The config API is also very much a WIP, I’d be glad to get feedback and suggestions !
