- [x] refactor lib into separate files, similar to NixOS/nixpkgs/lib. - [x] refactor ci to automatically generate derivations from flake outputs - [x] remove cluttered indirection statements throughout the codebase - [x] refactor hosts to allow for upcoming integration tests - [x] improve ambiguity in the existing docs - [x] add [BORS](https://bors.tech) support - [x] add initial integration test - [x] write tests documentation - [x] test lib - [x] improve version string generation, and do so automatically for pkgs/flake.nix sources Clean up the codebase as best we can in preparation for #152 and add tests. From now on, all PRs will be merged with BORS.

Packages
Similar to modules, the pkgs directory mirrors the upstream nixpkgs/pkgs, and for the same reason; if you ever want to upstream your package, it's as simple as dropping it into the nixpkgs/pkgs directory.
The only minor difference is that, instead of adding the callPackage
call to
all-packages.nix
, you just add it the the default.nix in this directory,
which is defined as a simple overlay.
This overlay is set as the default overlay
output attribute for the flake.
And all the packages are exported via packages.<system>.<pkg-name>
, for all
the supported systems listed in the package's meta.platforms
attribute.
And, as usual, every package in the overlay is also available to any NixOS host.
Automatic Source Updates
There is the added, but optional, convenience of declaring your sources in
pkgs/flake.nix as an input. You can then access them from the srcs
package.
This allows updates to be managed automatically by simply
updating the lock file. No
more manually entering sha256 hashes!
As an added bonus, version strings are also generated automatically from either the flake ref, or the date and git revision of the source. For examples, definitely checkout the community branch.
Example
pkgs/development/libraries/libinih/default.nix:
{ stdenv, meson, ninja, lib, srcs, ... }:
let inherit (srcs) libinih; in
stdenv.mkDerivation {
pname = "libinih";
# version will resolve to 53, as specified in the final example below
inherit (libinih) version;
src = libinih;
buildInputs = [ meson ninja ];
# ...
}
pkgs/default.nix:
final: prev: {
libinih = prev.callPackage ./development/libraries/libinih { };
}
pkgs/flake.nix:
{
description = "Package sources";
inputs = {
libinih.url = "github:benhoyt/inih/r53";
libinih.flake = false;
};
}
