void-packages/doc/BINPKG_REPOSITORY

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.
	- location-local: local path to the repository.
	- location-remote: remote URI repository.
	- total-pkgs: total of number of available packages.

"location-local" will always be created, and it might be exported via
a remote location specified with "location-remote".

The package dictionary will be the same than the one available in
package's metadata directory "/var/cache/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>location-local</key>
	<string>/xbps/repo/local</string>
	<key>location-remote</key>
	<string>http://www.xbps-remote.org/repo/public</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>
			...

		...
	</array>
</dict>

To build binary packages from all currently installed packages in
XBPS_MASTERDIR:

	$ xbps-src build-pkg all

To generate the repository package index in default location
XBPS_PACKAGESDIR (an additional path can be specified for another
alternate location):

	$ xbps-src genindex

After this you can add your own local repository with binary packages:

	$ xbps-bin 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-bin 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-bin repo-rm /path/to/dir

To show information about available packages in the repository pool:

	$ xbps-bin show package

To search for binary packages by specifying a string:

	$ xbps-bin search mypkg
