3 * @defgroup Parser Parser
7 * File for Parser and related classes
12 * PHP Parser - Processes wiki markup (which uses a more user-friendly
13 * syntax, such as "[[link]]" for making links), and provides a one-way
14 * transformation of that wiki markup it into XHTML output / markup
15 * (which in turn the browser understands, and can display).
18 * There are five main entry points into the Parser class:
20 * produces HTML output
22 * produces altered wiki markup.
24 * removes HTML comments and expands templates
26 * Cleans a signature before saving it to preferences
28 * Extracts sections from an article for section editing
30 * Removes <noinclude> sections, and <includeonly> tags.
33 * objects: $wgLang, $wgContLang
35 * NOT $wgArticle, $wgUser or $wgTitle. Keep them away!
38 * $wgUseTex*, $wgUseDynamicDates*, $wgInterwikiMagic*,
39 * $wgNamespacesWithSubpages, $wgAllowExternalImages*,
40 * $wgLocaltimezone, $wgAllowSpecialInclusion*,
43 * * only within ParserOptions
50 * Update this version number when the ParserOutput format
51 * changes in an incompatible way, so the parser cache
52 * can automatically discard old data.
