HotCat V2.10
Ajax-based simple Category manager. Allows adding/removing/changing categories on a page view.
Supports multiple category changes, as well as redirect and disambiguation resolution. Also
plugs into the upload form. Search engines to use for the suggestion list are configurable, and
can be selected interactively.
Authors:
V0.0: July 2007 - 2010-05-26: original version by [[User:Magnus Manske]], with lots of
additions by many editors, notably [[User:Dschwen]], [[User:TheDJ]], [[User:Superm401]],
and [[User:Lupo]]. No explicit license, assumed multi-licensed GFDL and CC-BY-SA-3.0 per
normal wiki submissions.
V2.0: April-May 2010: [[User:Lupo]]. Complete rewrite reusing only a little code from V0.0.
V2.1: May 2010: [[User:Merlissimo]] (added features: namespace case insensitive, subcategory
engine, category template mapping for removing; developed at de-Wikipedia.)
V2.2: May 2010: [[User:Lupo]] (porting additions from de-WP to the Commons, auto-localization
of template namespace name, cleanup, various other improvements. New features:
highlighting of changed categories, enabling/disabling save button, search engine name
localization, parent category engine).
V2.3: Aug 2010: [[User:Lupo]]: page up/down for scrolling in suggestion lists; suggestion list
size configurable; minor bug fixes.
V2.4: Oct 2010: [[User:TheDJ]] & [[User:Lupo]]: switch to not enable on upload form, ability to
load translations from the Commons. Major/minor edit flag configurable; and fix a minor
bug with the "Warn upon empty edit summary" user preference.
V2.5: Jan 2011: [[User:Lupo]]: blacklist
V2.6: Feb 2011: [[User:Ciencia Al Poder]] & [[User:Lupo]]: get rid of old URI-param based edit
interface, preventing unwanted single-category changes following malicious links
V2.7: March 2011: [[User:Lupo]]: fixes for being loaded as a gadget through the resource loader.
V2.8: July 2011: [[User:Lupo]]: don't remove "uncategorized" template if only hidden categories
are added.
V2.9: July 2011: [[User:Lupo]]: properly delay start-up of HotCat until localizations are loaded.
Also fix skipping interwikis and newline before new category.
V2.10:Sep 2011: [[User:Lupo]]: make compatible with new UL-LI DOM for categories, and adapt for
protocol-relative URLs.
