Detailed Description

General purpose client for https://download.moodle.org/api/.

The API provides proxy access to public information about plugins available in the Moodle Plugins directory. It is used when we are checking for updates, resolving missing dependecies or installing a plugin. This client can be used to:

• obtain information about particular plugin version
• locate the most suitable plugin version for the given Moodle branch

TODO:

• Convert core\update\checker to use this client too, so that we have a single access point for all the API services.
• Implement client method for pluglist.php even if it is not actually used by the Moodle core.

moodle branch in the X.Y format (e.g. 2.9, 3.0, 3.1 etc)

find_plugin()

core\update\api::find_plugin	(		$component,
			$reqversion = ANY_VERSION,
			$branch = null )

Locate the given plugin in the plugin directory.

Uses pluginfo.php end-point to find a plugin with the given component name, that suits best for the given Moodle core branch. Minimal required plugin version can be specified. This is typically used for resolving dependencies.

False is returned on error, or if there is no plugin with such component name found in the plugins directory via the API.

If a plugin with the given component name is found, data about the plugin are returned as an object. The ->version property of the object contains the information about the particular plugin version that matches best the given critera. The ->version property is false if no suitable version of the plugin was found (yet the plugin itself is known).

Parameters

string	$component	frankenstyle name of the plugin
string | int	$reqversion	minimal required version of the plugin, defaults to ANY_VERSION
int	$branch	moodle core branch such as 29, 30, 31 etc, defaults to $CFG->branch
