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.
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.
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;
};
}
