From a3a1ec57aaa3b008cc21a0150f08ab1a4248c179 Mon Sep 17 00:00:00 2001 From: Marcel de Rooy Date: Wed, 25 May 2016 13:37:49 +0200 Subject: [PATCH] Bug 16586: Koha Plugins: Limit results of GetPlugins by metadata It would be helpful if we could find a plugin based on some metadata tag as returned by the plugin. This extends the use of GetPlugins that already supports searching on method. GetPlugins is used in: admin/edi_accounts.pl, plugins/plugins-home.pl and tools/stage-marc-import.pl. The changes in these three scripts are minimal and just related to parameter passing. Test t/db_dependent/Plugins.t includes another test for GetPlugins. In this regard a metadata tag has been added to t/Koha/Plugins/Test.pm. NOTE: This adjustment will also be used in a redesign for bug 15545. Test plan: Run t/db_dependent/Plugins.t. Enable pref UseKohaPlugins and config var enable_plugins. Go to plugins-home.pl. Verify that it still lists your plugins. Bonus: Check edi_accounts or stage-marc-import.pl if you have a working plugin for that.
