This requires minor changes in various parts of MediaWiki, and being extra careful about cached rendered pages' HTML. Fun fact: editsection links are not made in Parser. They're made in Linker, in Skin *and* in ParserOutput. Client-side code and screen-scrapers will have to be adjusted to handle both cases (old HTML will still be visible on cached page renders until they are purged); extensions using the DoEditSectionLink or EditSectionLink hooks might need adjustments as well. * Linker: Change the HTML of pages to move the link itself from the beginning of the heading (before <span class="mw-headline">) to the end of the heading (after the span). * Skin: Change the class from .editsection to .mw-editsection; we use this opportunity to clean up old cruft, and this makes it much easier to handle cached renders (by just detecting the old class). * ParserOutput: Implement a horrible hack to support cached parser outputs with the old order of items. * Ensure everything that should support both classes supports both classes (this includes print stylesheets and some scripts). * Implement styles for the new look for all the skins (did this in shared.css; the styles are non-intrusive and can be overridden easily, and all of the skins were using the same look before).

/**
|
|
* Set a property to be stored in the page_props database table.
|
|
*
|
|
* page_props is a key value store indexed by the page ID. This allows
|
|
* the parser to set a property on a page which can then be quickly
|
|
* retrieved given the page ID or via a DB join when given the page
|
|
* title.
|
|
*
|
|
* setProperty() is thus used to propagate properties from the parsed
|
|
* page to request contexts other than a page view of the currently parsed
|
|
* article.
|
|
*
|
|
* Some applications examples:
|
|
*
|
|
* * To implement hidden categories, hiding pages from category listings
|
|
* by storing a property.
|
|
*
|
|
* * Overriding the displayed article title.
|
|
* @see ParserOutput::setDisplayTitle()
|
|
*
|
|
* * To implement image tagging, for example displaying an icon on an
|
|
* image thumbnail to indicate that it is listed for deletion on
|
|
* Wikimedia Commons.
|
|
* This is not actually implemented, yet but would be pretty cool.
|
|
*
|
|
* @note: Do not use setProperty() to set a property which is only used
|
|
* in a context where the ParserOutput object itself is already available,
|
|
* for example a normal page view. There is no need to save such a property
|
|
* in the database since it the text is already parsed. You can just hook
|
|
* OutputPageParserOutput and get your data out of the ParserOutput object.
|
|
*
|
|
* If you are writing an extension where you want to set a property in the
|
|
* parser which is used by an OutputPageParserOutput hook, you have to
|
|
* associate the extension data directly with the ParserOutput object.
|
|
* Since MediaWiki 1.21, you can use setExtensionData() to do this:
|
|
*
|
|
* @par Example:
|
|
* @code
|
|
* $parser->getOutput()->setExtensionData( 'my_ext_foo', '...' );
|
|
* @endcode
|
|
*
|
|
* And then later, in OutputPageParserOutput or similar:
|
|
*
|
|
* @par Example:
|
|
* @code
|
|
* $output->getExtensionData( 'my_ext_foo' );
|
|
* @endcode
|
|
*
|
|
* In MediaWiki 1.20 and older, you have to use a custom member variable
|
|
* within the ParserOutput object:
|
|
*
|
|
* @par Example:
|
|
* @code
|
|
* $parser->getOutput()->my_ext_foo = '...';
|
|
* @endcode

|
* This method is provided to overcome the unsafe practice of attaching extra information to a

|
|

|
|
* To use setExtensionData() to pass extension information from a hook inside the parser to a
|
|
* hook in the page output, use this in the parser hook:
|
|
*
|
|
* @par Example:
|
|
* @code
|
|
* $parser->getOutput()->setExtensionData( 'my_ext_foo', '...' );
|
|
* @endcode
|
|
*
|
|
* And then later, in OutputPageParserOutput or similar:
|
|
*
|
|
* @par Example:
|
|
* @code
|
|
* $output->getExtensionData( 'my_ext_foo' );
|
|
* @endcode
|
|
*
|
|
* In MediaWiki 1.20 and older, you have to use a custom member variable
|
|
* within the ParserOutput object:
|
|
*
|
|
* @par Example:
|
|
* @code
|
|
* $parser->getOutput()->my_ext_foo = '...';
|
|
* @endcode
|
|
*

|
* @since 1.21
|
|
*
|
|
* @param string $key The key for accessing the data. Extensions should take care to avoid
|
|
* conflicts in naming keys. It is suggested to use the extension's name as a
|
|
* prefix.
|
|
*
|
|
* @param mixed $value The value to set. Setting a value to null is equivalent to removing
|
|
* the value.
