Hopefully my answer fits your question..
all-package .nix is basically
{ <some opts> } :
rec {
pkg1 = mkDerivation{ buildInputs=[ dep dep ]; };
pkg2 = mkDerivation{ buildInputs=[ dep dep ]; };
...
<your package>
};
Now you want to benefit from all-packages (thus using those dependencies
as arguments to your derivation without adding <your package> at the
place show above?
You can do this using the 'with' syntax
with (import <path to all-packages.nix>) {}:
(import <your file>) { inherit stdenv fetchurl gmp readline }
or perhaps more simple:
let pkgs = (import <all-packages.nix>) {}; in
(import <your file>) { inherit (pkgs) stdenv fetchurl gmp readline }
(both is untestet.. but should work.. :)
pay attention to the {} which means use default values for <some opts>.
I'm currently modyfing all-packages.nix myself and adding the
derivations there because I'm lazy and I want to commit them as soon as
they do compile..
