\Text_Wiki_Parse_Freelink

Parses for freelinked page links.

This class implements a Text_Wiki_Parse to find source text marked as a wiki freelink, and automatically create a link to that page.

A freelink is any page name not conforming to the standard StudlyCapsStyle for a wiki page name. For example, a page normally named MyHomePage can be renamed and referred to as ((My Home Page)) -- note the spaces in the page name. You can also make a "nice-looking" link without renaming the target page; e.g., ((MyHomePage|My Home Page)). Finally, you can use named anchors on the target page: ((MyHomePage|My Home Page#Section1)).

Properties

$conf

$conf : string

Configuration options for this parser rule.

Type

string

$regex

$regex : string

Regular expression to find matching text for this rule.

Type

string

$rule

$rule : string

The name of this rule for new token array elements.

Type

string

$wiki

$wiki : object

A reference to the calling Text_Wiki object.

This is needed so that each rule has access to the same source text, token set, URLs, interwiki maps, page names, etc.

Type

object

Methods

__construct()

__construct(  $obj)

Constructor for this parser rule.

Parameters

$obj

parse()

parse()

Abstrct method to parse source text for matches.

Applies the rule's regular expression to the source text, passes every match to the process() method, and replaces the matched text with the results of the processing.

process()

process(array  $matches) : \A

Generates a replacement for the matched text. Token options are:

'page' => the wiki page name (e.g., HomePage).

'text' => alternative text to be displayed in place of the wiki page name.

'anchor' => a named anchor on the target wiki page

Parameters

array $matches

An array of matches from the parse() method as generated by preg_replace_callback. $matches[0] is the full matched string, $matches[1] is the first matched pattern, $matches[2] is the second matched pattern, and so on.

Returns

\A —

delimited token to be used as a placeholder in the source text, plus any text priot to the match.

getConf()

getConf(string  $key, mixed  $default = null) : mixed

Simple method to safely get configuration key values.

Parameters

string $key

The configuration key.
mixed $default

If the key does not exist, return this value instead.

Returns

mixed —

The configuration key value (if it exists) or the default value (if not).

getAttrs()

getAttrs(string  $text) : array

Extract 'attribute="value"' portions of wiki markup.

This kind of markup is typically used only in macros, but is useful anywhere.

The syntax is pretty strict; there can be no spaces between the option name, the equals, and the first double-quote; the value must be surrounded by double-quotes. You can escape characters in the value with a backslash, and the backslash will be stripped for you.

Parameters

string $text

The "attributes" portion of markup.

Returns

array —

An associative array of key-value pairs where the key is the option name and the value is the option value.
