We are pleased to announce GNU Guix version 0.2, the second alpha release, representing 580 commits by 5 people over 4 months. • About 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 programming interface. http://www.gnu.org/software/guix/ • Download Here are the compressed sources and a GPG detached signature[*]: ftp://alpha.gnu.org/gnu/guix/guix-0.2.tar.gz ftp://alpha.gnu.org/gnu/guix/guix-0.2.tar.gz.sig Use a mirror for higher download bandwidth: http://www.gnu.org/order/ftp.html Here are the MD5 and SHA1 checksums: 4bdbbd736d0bbcb6cd7e28220c4ea1fe guix-0.2.tar.gz 051a65d1d7aa9a0ea69fe97d6d9a8b93fe09cca0 guix-0.2.tar.gz [*] 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: Autoconf 2.69 Automake 1.13.1 Makeinfo 5.1 • 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 details. *** 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 CMake packages. *** 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: (expression->initrd '(begin (mkdir "/proc") (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 highlights. *** 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. Please report bugs to address@hidden Ludovic, on behalf of the Guix team.
