GNU Guix is Nix[0] from Guile[1]!
Concretely, it allows Nix package management to be done entirely in
Scheme. The goal is to investigate whether Scheme, and in particular
the ability to define EDSLs, would allow it to fulfill the role of the
Nix language.

* Hacking
Guix currently depends on the following packages:
- [[http://gnu.org/software/guile/][GNU Guile 2.0.x]]
- [[http://nixos.org/nix/][Nix]]
- [[http://gnupg.org/][GNU libgcrypt]]
Optionally, packages from Nixpkgs may be transparently reused from Guix.
For this to work, you need to have a checkout of the Nixpkgs repository;
the `--with-nixpkgs' option allows you to let `configure' know where the
Nixpkgs checkout is.
- [[http://nixos.org/nixpkgs/][Nixpkgs]]
When building Guix from a checkout, the following packages are also
required:
- [[http://www.gnu.org/software/autoconf/][GNU Autoconf]]
- [[http://www.gnu.org/software/automake/][GNU Automake]]
- [[http://www.gnu.org/software/gettext/][GNU Gettext]]
The "autoreconf -vi" command can be used to generate the build system
infrastructure; it reports an error if an inappropriate version of the
above packages is being used.
* How It Works
Guix does the high-level preparation of a /derivation/. A derivation is
the promise of a build; it is stored as a text file under
=/nix/store/xxx.drv=. The (guix derivations) module provides the
`derivation' primitive, as well as higher-level wrappers such as
`build-expression->derivation'.
Guix does remote procedure calls (RPCs) to the Nix daemon (the
=nix-worker --daemon= command), which in turn performs builds and
accesses to the Nix store on its behalf. The RPCs are implemented in
the (guix store) module.
* Contact
The repository is at <https://gitorious.org/guix/>.
Please email <ludo@gnu.org> or <nix-dev@lists.science.uu.nl>, or
join #guile or #nixos on irc.freenode.net or `civodul'.
* Related software
- [[http://nixos.org][Nix, Nixpkgs, and NixOS]], functional package manager and associated
software distribution, are the inspiration of Guix
- [[http://www.gnu.org/software/stow/][GNU Stow]] builds around the idea of one directory per prefix, and a
symlink tree to create user environments
- [[http://www.pvv.ntnu.no/~arnej/store/storedoc_6.html][STORE]] shares the same idea
- [[https://live.gnome.org/OSTree/][GNOME's OSTree]] allows bootable system images to be built from a
specified set of packages
- The [[http://www.gnu.org/s/gsrc/][GNU Source Release Collection]] (GSRC) is a user-land software
distribution; unlike Guix, it relies on core tools available on the
host system
