Member Function Documentation

Parser::areSubpagesAllowed ( )

Return true if subpage links should be expanded on this page.

Returns
bool

Definition at line 1896 of file Parser.php.

{
# Some namespaces don't allow subpages
global $wgNamespacesWithSubpages;
return !empty($wgNamespacesWithSubpages[$this->mTitle->getNamespace()]);
Parser::argSubstitution (   $matches)
private

Triple brace replacement – used for template arguments.

Definition at line 3333 of file Parser.php.

{
$arg = trim( $matches['title'] );
$text = $matches['text'];
$inputArgs = end( $this->mArgStack );
if ( array_key_exists( $arg, $inputArgs ) ) {

}
return $text;
Parser::armorLinks (   $text)

Insert a NOPARSE hacky thing into any inline links in a chunk that's going to go through further parsing steps before inline URL expansion.

In particular this is important when using action=render, which causes full URLs to be included.

Oh man I hate our multi-layer parser!

Parameters
stringmore-or-less HTML
Returns
string less-or-more HTML with NOPARSE bits

Definition at line 1887 of file Parser.php.

{
return preg_replace( '/\b(' . wfUrlProtocols() . ')/',
"{$this->mUniqPrefix}NOPARSE$1", $text );
Parser::attributeStripCallback ( &  $text,
  $args 
)
private

#@+ Callback from the Sanitizer for expanding items found in HTML attribute values, so they can be safely tested and escaped.

Parameters
string$text
array$args
Returns
string

Definition at line 4502 of file Parser.php.

{
$text = $this->replaceVariables( $text, $args );
$text = $this->mStripState->unstripBoth( $text );
return $text;
Parser::braceSubstitution (   $piece)
private

Return the text of a template, after recursively replacing any variables or templates within the template.

Parameters
array$pieceThe parts of the template $piece['text']: matched text $piece['title']: the title, i.e. the part before the | $piece['parts']: the parameter array
Returns
string the text of the template

Clear Parser state.

Prefix for temporary replacement strings for the multipass parser. should never appear in input as it's disallowed in XML. Using it at the front also gives us a little extra robustness since it shouldn't match when butted up against identifier-like string constructs.

#@-

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
$textPage wikitext
$sectionNumbered section. 0 pulls the text before the first heading; other numbers will pull the given section along with its lower-level subsections.
$modeOne of "get" or "replace"
$newtextReplacement text for section data.
Returns
string for "get", the extracted section text. for "replace", the whole page with the section replaced.

Parser::formatHeadings (   $text,

)
private

This function accomplishes several tasks: 1) Auto-number headings if that option is enabled 2) Add an [edit] link to sections for logged in users who have enabled the option 3) Add a Table of contents on the top for users who have enabled the option 4) Auto-anchor headings.

It loops through all headlines, collects the necessary data, then splits up the string and re-inserts the newly formatted headlines.

Parameters
string$text

Parser::makeKnownLinkHolder (   $nt,

Render a forced-blue link inline; protect against double expansion of URLs if we're in a mode that prepends full URL prefixes to internal links.

Since this little disaster has to split off the trail text to avoid breaking URLs in the following text without breaking trails on the wiki links, it's been made into a horrible function.

Parameters
Title$nt
string$text
string$query
string$trail
string$prefix
Returns
string HTML-wikitext mix oh yuck

Parser::makeLinkHolder ( &  $nt,
  $text = '',
  $query = '',
  $trail = '',

Make a link placeholder.

The text returned can be later resolved to a real link with replaceLinkHolders(). This is done for two reasons: firstly to avoid further parsing of interwiki links, and secondly to allow all existence checks and article length checks (for stub links) to be bundled into a single query.

Parser::replaceVariables (   $text,

Parameters

Parser::setFunctionHook (   $id,

  $flags = 0 
)

Create a function, e.g.

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

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 noparse Unsafe HTML tags should not be stripped, etc. noargs Don't replace triple-brace arguments in the return value isHTML The returned text is HTML, armour it against wikitext transformation

Parameters
string$idThe magic word ID
mixed$callbackThe callback function (and object) to use
integer$flagsa combination of the following flags: SFH_NO_HASH No leading hash, i.e. {{plural:...}} instead of {{if:...}}
Returns

Parser::setHook (   $tag,

)

Create an HTML-style tag, e.g.

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

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

Parameters
mixed$tagThe tag to use, e.g. 'hook' for <hook>
