=head2 GetPlugins
|
|
|

This will return a list of all available plugins, optionally limited by
|
|
method or metadata value.
|
|
|
|
my @plugins = Koha::Plugins::GetPlugins({
|
|
method => 'some_method',
|
|
metadata => { some_key => 'some_value' },
|
|
});
|
|
|
|
The method and metadata parameters are optional.
|
|
Available methods currently are: 'report', 'tool', 'to_marc', 'edifact'.
|
|
If you pass multiple keys in the metadata hash, all keys must match.
