** 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 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. See
|
|
|
|
|
|
the manual for details.
|
|
|
|
|
|
|
|
|
|
|
|
*** 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.
|
|
|
|
|
|
|
|
|
|
|
|
*** (guix download) now supports HTTPS, using GnuTLS
|
|
|
|
|
|
|
|
|
|
|
|
It allows package source tarballs to be retrieved over HTTPS.
|
|
|
|
|
|
|
|
|
|
|
|
** Programming interfaces
|
|
|
|
|
|
|
|
|
|
|
|
*** 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.
|
|
|
|
|
|
|
|
|
|
|
|
** GNU distribution
|
|
|
|
|
|
|
|
|
|
|
|
Many updates and additions have been made to the distribution. Here are the
|
|
|
|
|
|

|
|
|
|
