What are interesting, unique, and/or non-standard uses of Nix?

Wanted to include a couple examples, but one reason I’m starting this thread is that I lost most of my saves…but I remember about one project using the Nix store for document publishing purposes and perhaps a GIS one as well.

Here are two that come to mind:

Fractalide is a programming language built on top of Nix: GitHub - fractalide/fractalide: Reusable Reproducible Composable Software

Styx is a static site generator that uses Nix to compose the output: Home - Styx Static Site Generator

Was able to find some of the links I lost:

@toraritte I am currently messing around with a GIS processing pipeline using hydra; ingest from S3, content-addressed dataflow pipeline, egress back to S3. Is there some prior art on this?

I haven’t read either the blog or static site thing, but there’s at least one static site generator using nix:

I am working on my personal dotfiles manager! It is not ready because I do not understand Nix so much…

There may be as I clearly remember a post from around 2018/2019 but I couldn’t find it again… If I do, I’ll make sure to post it. Sorry.


@AndersonTorres Please share it, if you are comfortable with it - sometimes one can learn the most from a project in its early stages. I think it counts especially when it comes to Nix*; I’ve been trying to get a working understanding of it, but for some reason it feels notoriously hard. I remember that I’ve become productive with Erlang/Elixir within 6 months, with very minimal programming background, but Nix feels ever so elusive. One of these days…:slight_smile:

Not written in Nix, but for Nix: I wanted to take advantage of Nix store paths to provide better caching for static websites, and ended up writing a webserver for serving flake-built websites with zero-downtime rebuilds.

Just linking the thread on Fractalide

A dump of some blogs made in Nix:

  • Adding this thread; most notably because of the question:

    Also, do you have any general tips for derivation that output data/images ?

  • Found this default.nix by accident in the online repo of Chris Warburton that seems to be a build expression for a Tex document.

First I was confused that the repo was empty when I realized that content is in the different branches:)


Anyway, another entry: Unifying package managers, workflow engines, and containers: Computational reproducibility with BioNix - Here’s the corresponding GitHub repo and video.

Just realized that Nix “user environments” are also belong in this list as they are not software components/packages themselves but a convenience to provide immutable generations of symlinks to “installed” or “active” software.
