Detailed Description

PHP Parser - Processes wiki markup (which uses a more user-friendly syntax, such as "[[link]]" for making links), and provides a one-way transformation of that wiki markup it into (X)HTML output / markup (which in turn the browser understands, and can display).

There are seven main entry points into the Parser class:

Parser::parse() produces HTML output
Parser::preSaveTransform() produces altered wiki markup
Parser::preprocess() removes HTML comments and expands templates
Parser::cleanSig() and Parser::cleanSigInSig() cleans a signature before saving it to preferences
Parser::getSection() return the content of a section from an article for section editing
Parser::replaceSection() replaces a section by number inside an article
Parser::getPreloadText() removes <noinclude> sections and <includeonly> tags

Warning: $wgUser or $wgTitle or $wgRequest or $wgLang. Keep them away!

Settings:: $wgNamespacesWithSubpages

Settings only within ParserOptions:: $wgAllowExternalImages $wgAllowSpecialInclusion $wgInterwikiMagic $wgMaxArticleSize

◆ getExternalLinkAttribs()

Parser::getExternalLinkAttribs ( $url )

Get an associative array of additional HTML attributes appropriate for a particular external link.

This currently may include rel => nofollow (depending on configuration, namespace, and the URL's domain) and/or a target attribute (depending on configuration).

Access: internal

Parameters

string $url URL to extract the domain from for rel => nofollow if appropriate

◆ getExternalLinkRel()

static Parser::getExternalLinkRel	(		$url = false,

Get the rel attribute for a particular external link.

Since: 1.21

Access: internal

Parameters

string \| bool	$url	Optional URL, to extract the domain from for rel => nofollow if appropriate
LinkTarget \| null	$title	Optional LinkTarget, for wgNoFollowNsExceptions lookups

Returns: string|null Rel attribute for $url

References $title, and wfMatchesDomainList().

Referenced by Linker\makeExternalLink().

◆ getFlatSectionInfo()

Parser::getFlatSectionInfo ( $text )

Get an array of preprocessor section information.

Preprocessor sections are those identified by wikitext-style syntax, not HTML-style syntax. Templates are not expanded, so these sections do not include sections created by templates or parser functions. This is the same definition of a section as used by section editing, but not the same as TOC generation.

These sections are typically smaller than those acted on by getSection() and replaceSection() since they are not nested. Section nesting could be reconstructed from the heading levels.

The return value is an array of associative array info structures. Each associative array contains the following keys, describing a section:

index: An integer identifying the section.

◆ parseExtensionTagAsTopLevelDoc()

Needed by Parsoid/PHP to ensure all the hooks for extensions are run in the right order.

The primary differences between this and recursiveTagParseFully are: (a) absence of $frame (b) passing true to internalParseHalfParse so all hooks are run (c) running 'ParserAfterParse' hook at the same point in the parsing pipeline when parse() does it. This kinda mimics Parsoid/JS behavior where exttags are processed by the M/w API.

This is a temporary convenience method and will go away as we proceed further with Parsoid <-> Parser.php integration.

◆ recursiveTagParse()

Parser::recursiveTagParse	(		$text,

Half-parse wikitext to half-parsed HTML.

This recursive parser entry point can be called from an extension tag hook.

The output of this function IS NOT SAFE PARSED HTML; it is "half-parsed" instead, which means that lists and links have not been fully parsed yet, and strip markers are still present.

Use recursiveTagParseFully() to fully parse wikitext to output-safe HTML.

Use this function if you're a parser tag hook and you want to parse wikitext before or after applying additional transformations, and you intend to return the result as hook output, which will cause it to go through the rest of parsing process automatically.

If $frame is not provided, then template variables (e.g., {{{1}}}) within $text are not expanded

Parameters

string	$text	Text extension wants to have parsed
-taint	$text	escapes_htmlnoent
bool \| PPFrame	$frame	The frame to use for expanding any template variables

			$flags = 0 )

Create a function, e.g.

{{sum:1|2|3}} The callback function should have the form: function myParserFunction( &$parser, $arg1, $arg2, $arg3 ) { ... }

Or with Parser::SFH_OBJECT_ARGS: function myParserFunction( $parser, $frame, $args ) { ... }

The callback may either return the text result of the function, or an array with the text in element 0, and a number of flags in the other elements. The names of the flags are specified in the keys. Valid flags are: found The text returned is valid, stop processing the template. This is on by default. nowiki Wiki markup in the return value should be escaped isHTML The returned text is HTML, armour it against wikitext transformation

Parameters

string	$id	The magic word ID
callable	$callback	The callback function (and object) to use
int	$flags	A combination of the following flags: Parser::SFH_NO_HASH No leading hash, i.e. {{plural:...}} instead of {{if:...}}

Parser::SFH_OBJECT_ARGS Pass the template arguments as PPNode objects instead of text. This allows for conditional expansion of the parse tree, allowing you to eliminate dead branches and thus speed up parsing. It is also possible to analyse the parse tree of the arguments, and to control the way they are expanded.

The $frame parameter is a PPFrame. This can be used to produce expanded text from the arguments, for instance: $text = isset( $args[0] ) ? $frame->expand( $args[0] ) : '';

For technical reasons, $args[0] is pre-expanded and will be a string. This may change in future versions. Please call $frame->expand() on it anyway so that your code keeps working if/when this is changed.

If you want whitespace to be trimmed from $args, you need to do it yourself, post- expansion.

Please read the documentation in includes/parser/Preprocessor.php for more information about the methods available in PPFrame and PPNode.

Exceptions

MWException

Returns: string|callable|null The old callback function for this name, if any

◆ setHook()

Parser::setHook	(		$tag,
		callable	$callback )

Create an HTML-style tag, e.g.

"<yourtag>special text</yourtag>" The callback should have the following form: function myParserHook( $text, $params, $parser, $frame ) { ... }

Transform and return $text. Use $parser for any required context, e.g. use $parser->getTitle() and $parser->getOptions() not $wgTitle or $wgOut->mParserOptions

Hooks may return extended information by returning an array, of which the first numbered element (index 0) must be the return string, and all other entries are extracted into local variables within an internal function in the Parser class.

This interface (introduced r61913) appears to be undocumented, but 'markerType' is used by some core tag hooks to override which strip array their results are placed in.

Parameters

string	$tag	The tag to use, e.g. 'hook' for "<hook>"
callable	$callback	The callback function (and object) to use for the tag

Exceptions

MWException

Returns: callable|null The old value of the mTagHooks array associated with the hook

◆ stripSectionName()

Parser::stripSectionName ( $text )

Strips a text string of wikitext for use in a section anchor.

Accepts a text string and then removes all wikitext from the string and leaves only the resultant text (i.e. the result of [[User:WikiSysop|Sysop]] would be "Sysop" and the result of [[User:WikiSysop]] would be "User:WikiSysop") - this is intended to create valid section anchors by mimicking the output of the parser when headings are parsed.

Parameters

string $text Text string to be stripped of wikitext for use in a Section anchor

Returns: string Filtered text string
