Gnus/5.130005 (Ma Gnus v0.5) Emacs/24.3 (gnu/linux)
We are pleased to announce GNU Guix version 0.2, the second alpha
release, representing 580 commits by 5 people over 4 months.
GNU Guix is a functional package manager and distribution of
the 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. Guix uses
mechanisms from the Nix package management tool, with a Guile Scheme
Here are the compressed sources and a GPG detached signature[*]:
Use a mirror for higher download bandwidth:
Here are the MD5 and SHA1 checksums:
[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify guix-0.2.tar.gz.sig
If that command fails because you don't have the required public key,
then run this command to import it:
gpg --keyserver keys.gnupg.net --recv-keys EA52ECF4
and rerun the 'gpg --verify' command.
This release was bootstrapped with the following tools:
• Changes since version 0.1 (excerpt from the NEWS file)
** Package management
*** Guix commands are now sub-commands of the “guix” program
Instead of typing “guix-package”, one now has to type “guix package”, and so
on. This has allowed us to homogenize the user interface and initial program
setup, and to allow commands to be upgradable through “guix pull”.
*** New “guix package --upgrade” option
As the name implies, this option atomically upgrades all the packages
installed in a profile or the set of packages matching a given regexp.
See “Invoking guix package” in the manual.
*** New “guix package --search” option
Performs a full text search in package synopses and descriptions, and returns
the matching packages in recutils format. See “Invoking guix package” in the
manual, for details.
*** New “guix pull” command
The command pulls the latest version of Guix–both the package management
modules and the distribution. See the manual for details.
*** New binary substituter
The “substituter” mechanism allows pre-built binaries to be transparently
downloaded instead of performing a build locally. Currently binaries are
available for x86_64 Linux-based GNU systems from http://hydra.gnu.org. The
distribution is continuously built and binaries are made available from there.
See http://hydra.gnu.org/jobset/gnu/master under “Job status” for the list of
available binary packages.
*** New “guix refresh” command
The command is used by Guix maintainers. It automatically updates the
distribution to the latest upstream releases of GNU software.
*** New “guix hash” command
Convenience command to compute the hash of a file. See the manual for
*** Nix daemon code updated
The daemon code from Nix, used by the ‘guix-daemon’ command, has been updated
to current Nix ‘master’.
** Programming interfaces
*** (guix download) now supports HTTPS, using GnuTLS
It allows package source tarballs to be retrieved over HTTPS.
*** New ‘native-search-path’ and ‘search-path’ package fields
Packages can define in their ‘native-search-path’ field environment variables
that define search paths and need to be set for proper functioning of the
package. For instance, GCC has ‘CPATH’ and ‘LIBRARY_PATH’ in its
‘native-search-path’, Perl has ‘PERL5LIB’, Python has ‘PYTHONPATH’, etc.
These environment variables are automatically set when building a package that
uses one of these.
*** Package inputs can be a function of the target system type
The ‘inputs’ field of a package can now be conditional on the value of
(%current-system). This is useful for packages that take system-dependent
tarballs as inputs, such as GNU/MIT Scheme.
*** New build systems
The ‘perl-build-system’, ‘python-build-system’, and ‘cmake-build-system’ have
been added. They implement the standard build systems for Perl, Python, and
*** Tools to build Linux initrds, QEMU images, and more
The (gnu packages linux-initrd) module provides a procedure to build a Linux
initrd (“initial RAM disk”). The initrd embeds Guile, which is used to
evaluate the given expression. The example below returns an initrd that
mounts the /proc file system and starts a REPL:
(mount "none" "/proc" "proc")
((@ (system repl repl) start-repl))))
More examples in the linux-initrd.scm file.
Experimental interfaces to produce and use QEMU images are provided by the
(gnu system vm) module. For instance, the
‘expression->derivation-in-linux-vm’ evaluates the given Scheme expression in
a QEMU virtual machine running the Linux kernel and Guile.
** GNU distribution
Many updates and additions have been made to the distribution. Here are the
*** Major updates
GCC 4.7.3 (the default) and GCC 4.8.0, Binutils 2.23.2, Guile 2.0.9,
Coreutils 8.20, GDB 7.6, Texinfo 5.1.
*** Noteworthy new packages
TeXLive, Xorg, GNU GRUB, GNU Parted, QEMU and QEMU-KVM, Avahi, Bigloo,
CHICKEN, Scheme48, Hugs, Python, Lua, Samba.
