Here is the simplest mediawiki extension you can write:
- in LocalSettings.php, add
include("extensions/circlextension.php");
- create a file extensions/circlextension.php:
<?php $wgExtensionFunctions[] = "wfcirclextension"; function wfcirclextension() { global $wgParser; $wgParser->setHook("circle", "circlehtml"); } function circlehtml($code, $argv) { $result="<svg><circle r=50 /></svg>"; return $result; }
- Now you can create a mediawiki page with the content
This is mediawiki-syntax <circle this goes into argv > this goes into code </circle>
- And you will see a circle on the resulting wiki page. Note the circle may not be complete.
Version 2
Version 2 could look like this:
<?php $wgExtensionFunctions[] = "wfcirclextension"; function wfcirclextension() { global $wgParser; $wgParser->setHook("circle", "circlehtml"); } function circlehtml($code, $argv) { $param=reset($argv); # get first value of array if (!is_numeric($param)) {$param=20;}; $result=" <svg width=".round($param*2)." height=".round($param*2)."> <circle r=$param cx=$param cy=$param /> </svg>"; $result=preg_replace("/\n/","",$result); return $result; }
