Extensions are additions to the MediaWiki code that perform special functions.

Syntax Highlighting

The Geshi syntax-highlighter extension has been installed on this wiki. For PHP code use <source lang="php">Your PHP code here</source>. Further information can be found here.

For example, inserting the following in your wiki page:

<source lang="php">
<?php
  echo "Hello World\n";
?>
</source>

will result in:

<?php
  echo "Hello World\n";
?>

• #expr: computes simple mathematical expressions;
• #if: if-then-else construct;
• #ifeq: compares two strings or numbers;
• #ifexists: determines if a particular page exists;
• #ifexpr: evaluates and expression and tests the result;
• #switch: switch/case statement;
• #time: time and date formatting function;
• #rel2abs: converts a relative to an absolute path;
• #titleparts: extracts parts of a page title.
