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 XHTML 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.

Globals used: object: $wgContLang

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

Settings:: $wgLocaltimezone $wgNamespacesWithSubpages

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

Parser::extractSections	(	$	text,
		$	section,
		$	mode,
		$	newText = `''`
	)		`[private]`

Break wikitext input into sections, and either pull or replace some particular section's text.

External callers should use the getSection and replaceSection methods.

Parameters:

string	$text	Page wikitext
string	$section	a section identifier string of the form: "<flag1> - <flag2> - ... - <section number>"

Currently the only recognised flag is "T", which means the target section number was derived during a template inclusion parse, in other words this is a template section edit link. If no flags are given, it was an ordinary section edit link. This flag is required to avoid a section numbering mismatch when a section is enclosed by "<includeonly>" (bug 6563).

The section number 0 pulls the text before the first heading; other numbers will pull the given section along with its lower-level subsections. If the section is not found, $mode=get will return $newtext, and $mode=replace will return $text.

Section 0 is always considered to exist, even if it only contains the empty string. If $text is the empty string and section 0 is replaced, $newText is returned.

Parameters:

string	$mode	one of "get" or "replace"
string	$newText	replacement text for section data.

Returns:: String: for "get", the extracted section text. for "replace", the whole page with the section replaced.

Definition at line 5442 of file Parser.php.

static Parser::extractTagsAndParams	(	$	elements,
		$	text,
		&$	matches,
		$	uniq_prefix = `''`
	)		`[static]`

Replaces all occurrences of HTML-style comments and the given tags in the text with a random marker and returns the next text.

The output parameter $matches will be an associative array filled with data in the form:

   'UNIQ-xxxxx' => array(
     'element',
     'tag content',
     array( 'param' => 'x' ),
     '<element param="x">tag content</element>' ) )

Any flag added to the $flags parameter here, or any other parameter liable to cause a change in the DOM tree for a given text, must be passed through the section identifier in the section edit link and thus back to extractSections().

The output of this function is currently only cached in process memory, but a persistent cache may be implemented at a later date which takes further advantage of these strict dependency requirements.

Parameters:

string	$text	the text to transform
	$frame	PPFrame Object describing the arguments passed to the template. Arguments may also be provided as an associative array, as was the usual case before MW1.12. Providing arguments this way may be useful for extensions wishing to perform variable replacement explicitly.

Parser::serializeHalfParsedText ( $ text )

Save the parser state required to convert the given half-parsed text to HTML.

"Half-parsed" in this context means the output of recursiveTagParse() or internalParse(). This output has strip markers from replaceVariables (extensionSubstitution() etc.), and link placeholders from replaceLinkHolders().

Returns an array which can be serialized and stored persistently. This array can later be loaded into another parser instance with unserializeHalfParsedText(). The text can then be safely incorporated into the return value of a parser hook.

Parameters:

$text string

Returns:: array

Parser::setDefaultSort ( $ sort )

Mutator for $mDefaultSort.

Parameters:

Parser::setFunctionHook	(	$	id,
		$	callback,
		$	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 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
	$callback	Mixed: the callback function (and object) to use
	$flags	Integer: a combination of the following flags: SFH_NO_HASH No leading hash, i.e. {{plural:...}} instead of {{if:...}}

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.

Parser::setHook	(	$	tag,
		$	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 'markerName' is used by some core tag hooks to override which strip array their results are placed in. **Use great caution if attempting this interface, as it is not documented and injudicious use could smash private variables.**

This is probably obsoleted by things dealing with parser frames? The only extension currently using it is geoserver.

Since:: 1.10

Todo:: better document or deprecate this

Parameters:

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

Exceptions:

MWException

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

Definition at line 4805 of file Parser.php.

Parser::setUser ( $ user )

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 mimicing 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

Parser::unserializeHalfParsedText ( $ data )

Load the parser state given in the $data array, which is assumed to have been generated by serializeHalfParsedText().

The text contents is extracted from the array, and its markers are transformed into markers appropriate for the current Parser instance. This transformed text is returned, and can be safely included in the return value of a parser hook.

If the $data array has been stored persistently, the caller should first check whether it is still valid, by calling isValidHalfParsedText().

Parameters:

array $data Serialized data

Exceptions:

MWException

Returns:: String

Definition at line 5887 of file Parser.php.

Parser::validateSig ( $ text )

Check that the user's signature contains no bad XML.

Parameters:

$text String

Returns:: mixed An expanded string, or false if invalid.
