{{rel2abs: path }} or {{rel2abs: path | base path }}

Returns the absolute path to a subpage, relative to the current article title. Treats titles as slash-separated paths.

Following subpage link syntax instead of standard path syntax, an initial slash is treated as a relative path, and vice versa.

◆ runCount()

static MediaWiki\Extensions\ParserFunctions\ParserFunctions::runCount	(	Parser	$parser,

static

Returns number of occurrences of "substr" in "string".

Note: If "substr" is empty, a single space is used.

Parameters

Parser	$parser
string	$inStr
string	$inSubStr

Returns: int|string

			$inStr = `''`,
			$inDiv = `''`,
			$inPos = `0`,
			$inLim = `null`
	)

static

Breaks "string" into chunks separated by "delimiter" and returns the chunk identified by "position".

Note: Negative position can be used to specify tokens from the end. Note: If the divider is an empty string, single space is used instead. Note: Empty string is returned if there are not enough exploded chunks.

Parameters

Parser	$parser
string	$inStr
string	$inDiv
int	$inPos
int \| null	$inLim

Returns: string

◆ runPos()

static MediaWiki\Extensions\ParserFunctions\ParserFunctions::runPos	(	Parser	$parser,
			$inStr = `''`,
			$inNeedle = `''`,
			$inOffset = `0`
	)

static

Finds first occurrence of "needle" in "string" starting at "offset".

Note: If the needle is an empty string, single space is used instead. Note: If the needle is not found, empty string is returned.

Parameters

Parser	$parser
string	$inStr
int \| string	$inNeedle
int	$inOffset

Returns: int|string

			$inReplaceFrom = `''`,
			$inReplaceTo = `''`,
			$inLimit = `-1`
	)

static

Replaces each occurrence of "from" in "string" with "to". At most "limit" replacements are performed.

Note: Armored against replacements that would generate huge strings. Note: If "from" is an empty string, single space is used instead.

Parameters

Parser	$parser
string	$inStr
string	$inReplaceFrom
string	$inReplaceTo
int	$inLimit

Returns: mixed|string

			$inStr = `''`,
			$inNeedle = `''`

static

Finds last occurrence of "needle" in "string".

Note: If the needle is an empty string, single space is used instead. Note: If the needle is not found, -1 is returned.

Parameters

string	$inStr
int \| string	$inNeedle

Returns: int|string

			$inStr = `''`,
			$inStart = `0`,
			$inLength = `0`
	)

static

Returns substring of "string" starting at "start" and having "length" characters.

Note: If length is zero, the rest of the input is returned. Note: A negative value for "start" operates from the end of the "string". Note: A negative value for "length" returns a string reduced in length by that amount.

Parameters

Parser	$parser
string	$inStr
int	$inStart
int	$inLength

Returns: string
