BRIEF INTRODUCTION
------------------------------------------------------------------------------
A binary package built with xbps is a normal tar(1) archive, compressed
with any of the formats that libarchive supports, and it has the following
structure:
Package metadata
-----------------
/INSTALL
/REMOVE
/files.plist
/props.plist
Package data
-----------------
/usr
/var
/etc
...
Metadata info is stored in the "/var/db/xbps/metadata/$pkgname"
directory and two files will be always be present: files.plist
and props.plist.
The files.plist file contains the list of files/links/dirs that package
will install, as well as SHA256 hashes for files.
The props.plist file contains package metadata properties and has the
following structure:
<dict>
<key>pkgname</key>
<string>foo</string>
<key>version</key>
<string>3.40</string>
<key>maintainer</key>
<string>The Master BOFH <bofh@baobab.org> </string>
<key>short_desc</key>
<string>Foo is a virtual package</string>
<key>long_desc</key>
<string>
Foo is a virtual package to show how the metadata props.plist file works
with xbps handling binary packages.</string>
<key>architecture</key>
<string>x86_64</string>
<key>installed_size</key>
<integer>500000</integer>
<key>configuration_files</key>
<array>
<string>/etc/foo.conf</string>
...
</array>
<key>run_depends</key>
<array>
<string>bofh-2.0</string>
<string>blab-1.1</string>
...
</array>
...
</dict>
The INSTALL/REMOVE executables allows you to trigger any action
at pre/post installation/removal of the binary package.
The package's dictionary will also be written into the repository's package
index file, that describes information about a binary package on it.
See the BINPKG_REPOSITORY file for more info about repositories.
------------------------------------------------------------------------------
HOW TO USE BINARY PACKAGES
------------------------------------------------------------------------------
To install binary packages, firstly a repository must be created as well as
some binary packages for it. The flow for this task is:
1- xbps-src install <package>
2- xbps-src build-pkg all [requires sudo access]
3- xbps-repo genindex $XBPS_PACKAGES
4- xbps-repo add $XBPS_PACKAGES
5- xbps-bin install -r /rootdir <package>
So the tasks are: install the package into destdir (and all its dependencies),
build the binary package from the required package, generate the repository
index, add the repository into the pool and install the binary package.
Please note that by default, the xbps-* utils accept the -r flag, to specify
the root directory for all operations, in that case the package will be
installed into <rootdir> and metadata files into <rootdir>/var/db/xbps.
Don't forget to set this flag if you aren't using xbps as the primary
package manager in your system, otherwise it could overwrite some files!
See the BINPKG_REPOSITORY file for more info about repositories for
binary packages or SRCPKG_INFO for source packages.

BRIEF INTRODUCTION
------------------------------------------------------------------------------
A repository for binary packages contains the packages itself, and
an index file describing the information about available packages.
The structure for this file is just the same than the plist file used
to register installed packages, aka "an array of dictionaries" and
a "dictionary per package". Additional objects are added into the
main dictionary to specify more info, like:
- pkgindex-version: version used to build the index.
- total-pkgs: total of number of available packages.
The package dictionary will be the same than the one available in
package's metadata directory "/var/db/xbps/metadata/$pkgname/props.plist",
but some additional objects are added to provide enough info for
the repository itself:
- filename: name (and path relative to current dir) for the binary
package.
- filename-sha256: SHA256 hash of the binary package.
Here's how the package index plist file shall look like in a repository:
<dict>
<key>pkgindex-version</key>
<string>1.0</string>
<key>total-pkgs</key>
<integer>666</integer>
<key>available-packages</key>
<array>
<dict>
<key>pkgname</key>
<string>klibc</string>
<key>version</key>
<string>1.5.17</string>
<key>filename</key>
<string>klibc-1.5.17.x86_64.xbps</string>
<key>filename-sha256</key>
<string>7b0de0521983037107cc33f2b1514126432f86ac2be1ef9b9dc51a1e959ea777</string>
<key>architecture</key>
<string>x86_64</string>
<key>installed_size</key>
<integer>9471141</integer>
<key>maintainer</key>
<string>Juan RP xtraeme@gmail.com</string>
<key>short_desc</key>
<string>Minimal libc subset for use with initramfs</key>
<key>long_desc</key>
<string>
klibc is intended to be a minimalistic libc subset for use with initramfs.
It is deliberately written for small size, minimal entanglement, and
portability, not speed. It is definitely a work in progress and a lot of
things are still missing.</string>

HOW TO USE BINPKGS WITH REPOSITORIES
------------------------------------------------------------------------------
To build binary packages from all currently installed packages in
XBPS_MASTERDIR:
$ xbps-src build-pkg all
To generate the repository package index for your $XBPS_PACKAGESDIR
setting in the configuration file:
$ xbps-repo genindex /path/to/dir
Alternatively if you only want to register a single package:
$ xbps-repo add-pkgidx /package/repo /package/repo/<arch>/foo-1.2.xbps
After this you can add your own local repository with binary packages:
$ xbps-repo add /path/to/dir
Added repository at /path/to/dir (1.0) with 6 packages.
$
Once it's registered, you can start searching/installing/removing
binary packages. You can add multiple repositories, the order for searching
is the same than they were added; check it with:
$ xbps-repo list
/storage/xbps/binpkgs
/path/to/dir
$
The first repository that has the metadata for a package wins, if not found
it will search in all them until it's found. A repository can also be
unregistered from the pool:
$ xbps-repo remove /path/to/dir
To show information about available packages in the repository pool:
$ xbps-repo show package
To search for binary packages by specifying a shell pattern (see fnmatch(3)):
$ xbps-repo search 'foo*'

WHAT IS IT?
-----------------------------------------------------------------------------
xbps - xtraeme's binary package ystem.
xbps is a new binary package system, taken ideas from other free available
implementations, such as dpkg/apt, RPM, pacman and others. Metadata handling
as package databases are handled by proplib. Multiple compression formats
are supported in binary packages thanks to libarchive.
xbps has been designed for Linux, and for the moment I'm not interested to
make it work on any other random OS. xbps is the base to create a basic
Linux system.
-----------------------------------------------------------------------------
REQUIREMENTS
-----------------------------------------------------------------------------
xbps uses proplib, a property container object library and it's almost the
same one available for NetBSD. Be sure to have it installed before using
xbps. You can get it at:
http://code.google.com/p/portableproplib/
I'm also the human maintaining the portable proplib package. I'd suggest you
to install it into /usr/local to avoid issues with your distribution packages.
To build the xbps utils, you'll need for both shared and dynamic:
* asciidoc (to build the manpages)
* libarchive (devel pkg)
* proplib (devel pkg)
* openssl (devel pkg)
And the following packages as well to build the static binaries:
* attr (devel pkg with static lib)
* acl (devel pkg with static lib)
* zlib (devel pkg with static lib)
* bzip2 (devel pkg with static lib)
* xz (devel pkg with static lib)
Please note that when building the static binaries, the static libs
must match the requirements! please make sure that your installed
libarchive has all features built in (acl, zlib, bzip2, xz and openssl).
------------------------------------------------------------------------------
HOW TO USE IT
------------------------------------------------------------------------------
Before using xbps, some required utilities need to be built and installed
into $(PREFIX); by default they are installed into /usr/local.
You can do this by issuing "make" and "make install" as root in the top
level directory. See the REQUIREMENTS section above for required packages.
To build binary packages, you need xbps-src. It's stored in a public GIT
repository located at:
http://repo.or.cz/w/xbps.git
For information about binary packages, see the BINPKG_INFO file.

xbps-bin:
* Add support to install binary packages without any repository.
* Add a flag to reinstall a package version that is already installed,
overwritting files on disk and updating required_by if required.
Perhaps change the automatic-install object to false, like pkg_install
from NetBSD do.
* Implement shell style match patterns with fnmatch() for install, update
and remove.
* Make -f flag to overwrite files when installing, and to ignore
files with wrong checksum or unexistent when removing.
[PARTIAL: only unexistent files are ignored when removing]
libxbps:
* Add support to upgrade packages but overwritting current files;
this will fix libc, sh and others. An "essential" boolean obj
seems to be a good way to find such packages, like dpkg.
[PARTIAL: files are overwritten but obsolete files are not
taken into account yet]
