OpenGen/nix

This repo holds Nix flake, modules, packages, and reusable utility Nix language code for use across the OpenGen ecosystem.

Usage

Build an artifact

Currently, you can build a package directly like so:

nix build github.com:OpenGen/nix#sppl

Build an OCI image with an environment

OCI images consume these libraries and ones from other OpenGen repos, and are specified in another flake (excepting the base oci image):

nix build github.com:OpenGen/nix#ociImgLoom

Import utility code

To access the lib code exported by this flake, declare this repo as a flake input:

{
  inputs = {
    nixpkgs.url = ...
    opengen.url = "github:OpenGen/nix";
  };
  outputs = inputs@{ nixpkgs, opengen, ... }: let
    # call some function
    toolbox = opengen.lib.basicTools "aarch64-darwin";
  in {
    ...
  };
};

Packages

.#sppl

Python library by ProbSys packaged for python3.9 .

.#loom

Implementation of CrossCat in Python. NOTE: this ONLY builds for x86_64 architectures and only runs on linux, because it depends on platform-dependent distributions.

Your options are:

nix build '.#packages.x86_64-linux.loom'                      # same as `.#loom` if that is your OS/arch
nix build './envs-flake#packages.x86_64-darwin.ociImgLoom'

If you are running on Mac silicon (aarch64-darwin), that OCI image will run but behavior is not defined or supported.

.#loom.morePackages.distributions

Native library for probability distributions in python used by Loom. NOTE: this ONLY builds for x86_64 architectures and only runs on linux.

.#loom.morePackages.parsable

.#loom.morePackages.pymetis

.#loom.morePackages.goftests

.#loom.morePackages.tcmalloc

Other upstream python packages required by Distributions and/or Loom.

.#loom.ociImg

A Loom container image is also provided as a passthru attribute of loom. It can be built and loaded into your local Docker registry with the following command:

docker load -i $(nix build 'github:OpenGen/nix/loom-oci-img-attribute#loom.ociImg' --no-link --print-out-paths)
