[[http://www.gnu.org/software/guix/][GNU Guix]] (IPA: /ɡiːks/) is a purely functional package manager, and
associated free software distribution, for the [[http://www.gnu.org/gnu/gnu.html][GNU system]].  In addition
to standard package management features, Guix supports transactional
upgrades and roll-backs, unprivileged package management, per-user
profiles, and garbage collection.

It provides [[http://www.gnu.org/software/guile/][Guile]] Scheme APIs, including a high-level embedded
domain-specific languages (EDSLs) to describe how packages are to be
built and composed.

A user-land free software distribution for GNU/Linux comes as part of
Guix.

Guix is based on the [[http://nixos.org/nix/][Nix]] package manager.


* Hacking

GNU 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

GNU Guix is hosted at https://savannah.gnu.org/projects/guix/.

Guix and its distribution; email <gnu-system-discuss@gnu.org> for

* Guix & Nix

GNU Guix is based on [[http://nixos.org/nix/][the Nix package manager]].  It implements the same
package deployment paradigm, and in fact it reuses some of its code.
Yet, different engineering decisions were made for Guix, as described
below.

Nix is really two things: a package build tool, implemented by a library
and daemon, and a special-purpose programming language.  GNU Guix relies
on the former, but uses Scheme as a replacement for the latter.

Using Scheme instead of a specific language allows us to get all the
features and tooling that come with Guile (compiler, debugger, REPL,
Unicode, libraries, etc.)  And it means that we have a general-purpose
language, on top of which we can have embedded domain-specific languages
(EDSLs), such as the one used to define packages.  This broadens what
can be done in package recipes themselves, and what can be done around them.

Technically, Guix makes remote procedure calls to the nix-worker
daemon to perform operations on the store.  At the lowest level, Nix
“derivations” represent promises of a build, stored in .drv files in
the store.  Guix produces such derivations, which are then interpreted
by the daemon to perform the build.  Thus, Guix derivations can use
derivations produced by Nix (and vice versa).

With Nix and the [[http://nixos.org/nixpkgs][Nixpkgs]] distribution, package composition happens at
the Nix language level, but builders are usually written in Bash.
Conversely, Guix encourages the use of Scheme for both package
composition and builders.  Likewise, the core functionality of Nix is
written in C++ and Perl; Guix relies on some of the original C++ code,
but exposes all the API as Scheme.
