| 26 | * Some parser functions, and quite a bunch of stubs of parser functions. |
| 27 | * |
| 28 | * IMPORTANT NOTE: These parser functions are only used by the Parsoid-native |
| 29 | * template expansion pipeline, which is *not* the default or used in |
| 30 | * production. Normally core provides us SiteConfig and DataAccess objects |
| 31 | * that provide parser functions and other preprocessor functionality. |
| 32 | * |
| 33 | * There are still quite a few missing, see |
| 34 | * {@link http://www.mediawiki.org/wiki/Help:Magic_words} and |
| 35 | * {@link http://www.mediawiki.org/wiki/Help:Extension:ParserFunctions}. |
| 36 | * Instantiated and called by the {@link TemplateHandler} extension. |
| 37 | * Any `pf_<prefix>` |
| 38 | * matching a lower-cased template name prefix up to the first colon will |
| 39 | * override that template. |
| 40 | * |
| 41 | * The only use of this code is currently in parserTests and offline tests. |
| 42 | * But, eventually as the two parsers are integrated, the core parser tests |
| 43 | * implementation from $mw/includes/parser/CoreParserFunctions.php might |
| 44 | * move over here. |
