/* <nowiki>
AnonLoader, allows anons to load scripts specified in window.AnonLoaderScripts (which can be defined in MediaWiki:common.js) through portlet links
AnonLoader is public domain, irrevocably released as WTFPL Version 2[www.wtfpl.net/about/] by its author, Alexis Jazz.
Installation instructions:
* Create MediaWiki:Gadget-AnonLoader.js with the contents of this file.
* Add this line to MediaWiki:Gadgets-definition: "AnonLoader[ResourceLoader|dependencies=mediawiki.util,mediawiki.storage|targets=desktop,mobile|default|hidden]|AnonLoader.js"
* Put (for example) window.AnonLoaderScripts = ['CD','Factotum:gadget','dark-mode-toggle,dark-mode-toggle-pagestyles:gadget:Dark mode','dark-mode:gadget:Instant dark mode:urlLoad']; in MediaWiki:Common.js AND MediaWiki:Mobile.js (MobileFrontend doesn't load Common.js)
* Optional: add window.AnonLoaderShowAll=1 in common.js+mobile.js to show all gadgets without a collapsible menu.
AnonLoaderScripts format description:
Gadgets:
['GADGET1:gadget[:displayname][:urlLoad]','GADGET2[,GADGET3][,GADGET4]:gadget[:displayname]','GADGET5:gadget[:displayname]']
Only one gadget can have urlLoad. This will intercept links to add &withgadget=gadgetname. Dark mode requires this to prevent white flashes.
To load multiple gadgets for one entry, enter them separated by commas.
Scripts (that can't be loaded as gadgets):
['SCRIPTNAME1[:0][:displayname]','SCRIPTNAME2[:0][:displayname]','SCRIPTNAME3[:0][:displayname]']
If :gadget is added (HIGHLY RECOMMENDED) it will load ext.gadget.SCRIPTNAME, e.g. https://commons.wikimedia.beta.wmflabs.org/w/load.php?lang=en&modules=ext.gadget.AnonLoader
Otherwise it will load MediaWiki:Gadget-SCRIPTNAME.js. Insecure page titles are not supported.
If you include displayname that will be used for the link name.
Technically anons could modify their localStorage to load scripts/gadgets that aren't specified in AnonLoaderScripts, but they would still have to comply with the requirements of being a gadget or titled MediaWiki:Gadget-SCRIPTNAME.
There's no UI for that, but very meta, one could write a gadget for that and load it with AnonLoader.
