This is the master branch of nixpkgs, initially pulled from commit 8debf2f9a63d54ae4f28994290437ba54c681c7b
The intent of this repo is to be merged onto nixpkgs master. This will also be of help for https://git.suyu.dev/BoomMicrophone/suyu-nix-test
which I will need in order for development (it will also be helpful to know what to do for setting up the environment for the master server. Currently I am focusing on this so I can actually see what is still missing)
This repo will be removed once the PR to the nixpkgs github goes through

`callPackage' was described here:
http://www.mail-archive.com/nix-dev@cs.uu.nl/msg02624.html
It allows all-packages.nix to be shortened significantly (from 10152
to 6980 lines) by automatically filling in package functions'
required arguments from `pkgs'. That is, a function
{ stdenv, fetchurl, libfoo, libbar }: ...
can now be called as
callPackage ./<bla>.nix { };
rather than
import ./<bla>.nix {
inherit stdenv fetchurl libfoo libbar;
};
This reduces boring typing work when adding a dependency and reduces
the number of trivial commits to all-packages.nix.
Overrides or arguments that don't exist in `pkgs' can be passed
explicitly, e.g.,
callPackage ./<bla>.nix {
libfoo = libfoo_1_2_3;
};
The conversion was done automatically with a magic Perl regexp. I
checked that `nix-env' produces the same results before and after
(except for three packages that depend on webkit, which uses
deepOverride).
`callPackage' applies `makeOverridable' automatically, so almost
every package now exports an `override' function.
There are two downsides to using callPackage:
- Evaluation is a bit slower (about 15% on `nix-env -qa --drv-path
\*').
- There can be unexpected results for functions that have default
argument values. For instance, a function
{ libfoo ? null }: ...
called using `callPackage' will be passed a `libfoo' argument
provided that `pkgs.libfoo' exists. If this is used to control
whether a package has to have a certain dependency, you need to
explicitly write:
callPackage ./<bla>.nix {
libfoo = null;
};
