What does HackerNews think of rules_nixpkgs?

Rules for importing Nixpkgs packages into Bazel.

Language: Starlark

There is https://github.com/tweag/rules_nixpkgs which is something I wanted to look into.
I have spent a little bit of time working on a prototype of a setup like this, and have needed to write a lot of (hacky) glue and BUILD files.

I take it you have departed quite a bit from https://github.com/tweag/rules_nixpkgs ? Are you generating BUILD.bazel files for nixpkgs, or are you doing that by hand?

Cool, thanks for the link.

For what it's worth, we use rules_nixpkgs to source Postgres (for Linux and Darwin) as well as things such as C and Python toolchains, and it's been working really well. It does require that the machine have Nix installed, though, but that opens up access to Nix's wide array of prebuilt packages.

Nix is good for inter-package dependencies, while Bazel is good for internal dependencies. You could use Bazel to build your packages for Nix, and import your other projects into your BUILD files with https://github.com/tweag/rules_nixpkgs.
