* gnu/packages.scm (find-newest-available-packages):
New exported procedure.
* guix-build.in (newest-available-packages, find-best-packages-by-name):
New procedures.
(find-package): Use find-best-packages-by-name, to guarantee that
if a version number is not specified, only the newest versions will
be considered.
* guix-package.in (%options): Add --upgrade/-u option.
(newest-available-packages, find-best-packages-by-name, upgradeable?):
New procedures.
(find-package): Use find-best-packages-by-name, to guarantee that
if a version number is not specified, only the newest versions will
be considered.
(process-actions): Implement upgrade option.
* doc/guix.texi (Invoking guix-package): In the description of --install,
mention that if no version number is specified, the newest available
version will be selected.
* guix/ui.scm (fill-paragraph, string->recutils, package->recutils): New
procedures.
* guix-package.in (guix-package)[process-query]: Use `package->recutils'
to display package meta-data.
* tests/guix-package.sh: Adjust test.
* tests/ui.scm: New file.
* Makefile.am (TESTS): Add it.
* doc/guix.texi (Invoking guix-package): Adjust `--search'
documentation, and give an example.
Suggested by Andreas Enge <andreas@enge.fr> at
<http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00325.html>.
* guix-package.in (latest-profile-number): Remove.
(switch-symlinks): New procedure.
(roll-back)[switch-link]: Use it.
(guix-package)[process-actions]: Always choose NUMBER + 1 for the new
profile. Use `switch-symlinks' instead of `symlink'. Remove code to
delete PROFILE when it exists since `switch-symlinks' has the same
effect.
* tests/guix-package.sh: Adjust existing `--roll-back' tests.
* doc/guix.texi (Invoking guix-package): Document this `--roll-back'
behavior.
Suggested by Andreas Enge <andreas@enge.fr> at
<http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00316.html>.
* guix-package.in (roll-back): Check whether PROFILE is valid using
`file-exists?'. When NUMBER is zero, just emit a notice. When
PREVIOUS-NUMBER is zero and PREVIOUS-PROFILE does not exist, build the
empty profile, and link to it.
* tests/guix-package.sh: Add tests.
* doc/guix.texi (Invoking guix-package): Document the new behavior.
* doc/guix.texi (Invoking guix-build): Make it clear that `guix-build'
doesn't access the user's profile, and add cross-ref to `guix-package'.
Suggested by Nikita Karetnikov <nikita@karetnikov.org>.
* guix-build.in (guix-build)[find-package]: New procedure.
Use it instead of using `find-packages-by-name' directly.
Suggested by Andreas Enge <andreas@enge.fr>.
* tests/guix-build.sh: Add tests.
* doc/guix.texi (Invoking guix-build): Add `coreutils-8.20' as an
example. Fix guile-1.8 example.
* guix/packages.scm (cache): Change the `drv' argument to `thunk'.
Memoize all the return values of THUNK.
(cached-derivation): Remove.
(cached): New macro.
(package-derivation): Use `cached' instead of `(or (cached-derivation) …)'.
* doc/guix.texi (Defining Packages): Update accordingly.
Based on a patch by Nikita Karetnikov <nikita@karetnikov.org>.
* guix-package.in (profile-regexp): New procedure.
(latest-profile-number): Remove `%profile-rx', and use
`profile-regexp' instead.
(profile-number, roll-back): New procedure.
(show-help): Add `--roll-back'.
(%options): Likewise.
(guix-package)[process-actions]: First check whether `roll-back?' is
among OPTS, and call `roll-back' if it is, followed by a recursive
call to `process-actions'. Emit the "nothing to be done" message only
when INSTALL or REMOVE is non-empty.
* tests/guix-package.sh (readlink_base): New function.
Add tests for `--roll-back'.
* doc/guix.texi (Invoking guix-package): Document `--roll-back'.
Reported by Andreas Enge.
* guix-package.in (%profile-directory): Honor $NIX_STATE_DIR.
(guix-package)[ensure-default-profile]: Use it.
[process-actions]: Call it when the `profile' option is
%CURRENT-PROFILE.
* tests/guix-package.sh: Add installation test with $HOME set, using the
default profile.
* doc/guix.texi: Set @documentlanguage.
(Installation): Add reference to `INSTALL' and `README'.
(Requirements): Mention store sharing with Nix.
(Defining Packages): Update example to include `use-modules' clauses
and to use (guix licenses).
* distro/packages/libsigsegv.scm (libsigsegv): Use just a single output,
otherwise nothing ends up in `out' as a consequence of commit a06a99f.
Reported by Andreas Enge <andreas@enge.fr>.
* guix-package.in (guix-package): Create the %USER-ENVIRONMENT-DIRECTORY
symlink if it doesn't exist yet.
* doc/guix.texi (Invoking guix-package): Document it.
* guix-package.in (guix-package)[process-query]: For `list-available',
show the outputs of each package.
* doc/guix.texi (Invoking guix-package): Update accordingly.
* configure.ac: Change package name to "GNU Guix", and bug-report
address to `gnu-system-discuss@gnu.org'.
* doc/guix.texi: Replace "Guix" by "GNU Guix" in some places.
(Top, Introduction): Mention "for the GNU system".
