simplaret: simplepkg retrieval tool
-----------------------------------
Simplaret is a simplepkg tool used to download packages from local and remote repositories.
With simplaret, one can grab packages for all archictectures and versions of slackware-like
distributions that follows the mirror guidelines, allowing an easy management all
jails and slackware installations in a machine, no matter wich arquiteture or version
each one has.
It was inspired in swaret behavior but don't tries to get its complexity level, but
execute package download in a different way, where the local repository is organized
by archictecture and version. It can also search for packages.
Documentation
-------------
The always updated english documentation is hosted at http://slack.sarava.org/node/17
Downloading and installing
--------------------------
Simplaret comes with simplepkg, wich installation and configuration is detailed
at http://slack.sarava.org/node/15. Simplaret uses /etc/simplepkg/simplepkg.conf for
its definitions and /etc/simplepkg/repos.conf for repository information.
Repository organization
-----------------------
Simplaret local storage folder is defined through STORAGE parameter and is organized
in this manner:
$STORAGE/arch/version/
Packages from contributed repositories (i.e, not from an official distro mirror) are
stored at
$STORAGE/arch/version/repository-name/
This means, for example, that slack 10.2 packages are located in
$STORAGE/i386/10.2/
And the slack.sarava.org's slamd64 packages can be stored in a place such as
$STORAGE/x86_64/10.2/slack.sarava.org/
In the repository definition file (/etc/simplepkg/repos.conf), the entries must match
the following schema, something that remembers a swaret.conf:
ROOT-i386="http://slack.sarava.org/slackware/"
ROOT-x86_64="http://ftp.heanet.ie/pub/slamd64/"
REPOS-i386-10.2="slack.sarava.org%http://slack.sarava.org/packages/slackware/slackware-10.2/"
REPOS-x86_64-10.2="slack.sarava.org%http://slack.sarava.org/packages/slamd64/slamd64-10.2/"
Repositories defined as ROOT are those wich
- Have packages from the official distro or
- Are organized by version according to the mirror guidelines
Repositories defined as REPOS are those containing packages from a specific version or
non-oficial packages.
When simplaret searches for a package, precedence is given first for ROOT definitions and then
for REPOS ones. REPOS definitions should also include a identification name, delimited from
the repository URL by the special sign %.
Fetching the package list
-------------------------
After configured, simplaret can fetch the package list with
simplaret --update
This updates the package list from arch defined in DEFAULT_ARCH and version from DEFAULT_VERSION.
To fetch package listings for x86_64 (slamd64) and version 10.2, use
ARCH=x86_64 VERSION=10.2 simplaret --update
Searching
---------
To search for a package, use the following commands as examples:
simplaret --search coreutils
for a Slack/390 package,
ARCH=s390 simplaret --search x11
for slack 10.1 with contributed i686 packages,
ARCH=i686 VERSION=10.1 simplaret --search icecast
Downloading
-----------
To download a package,
simplaret --get icecast
Simplaret downloads the first package found with the precedence explaned above.
Future versions should contain an option to explicit get a package from a
specific repository.
Downloading patches
-------------------
From the PATCHES_DIR parameter is possible to specify a folder where patches are
placed, sorted by arch and version.
Patches for slack 10.2 are always located at
$PATCHES_DIR/i386/10.2/
In reality, patches are downloaded with a "simplaret --get" and stored in the $STORAGE
subfolder for its arch and version and a symlink is created in $PATCHES_DIR/$ARCH/$VERSION.
To grab all patches from an arch and version, use
ARCH=architecture VERSION=version simplaret --get-patches
Purging the cache
-----------------
Simplaret cache from an arch and version can be purged with a
simplaret --purge
But why use that?
-----------------
You may ask why someone wishes to use such tool.
Simplaret was written with a *x86 environment in mind, where lots of jails with different archs
and versions are installed. Suppose a x86_64 with the following chroots installed:
- slamd64 10.2
- slackware 10.2
- slackware 10.1 with additional i686 packages
- uSlack (i386 uClibc)
Keep all this stuff update manually is really a headache. Simplaret just tries to make it trivial.
