This is a Mediawiki extension that inserts JargonFile definitions on wiki pages.


The simplest way to do so is to insert <jargon /> in a page, that will use the current page title as lookup term.

Alternatively you can use <jargon>something</jargon>.

Pages using it are also automatically included in Category:Jargon.


If you find a missing page, simply insert <jargon /> (and nothing else) into the new page and save it.



To install copy into ./extensions/JargonExtension.php and then include("extensions/JargonExtension.php"); in LocalSettings.php as usual with Mediawiki extensions.

The extension uses the Debian package jargon. apt-get install jargon. (Also see vh).

$term = escapeshellarg($term);

$jargon=`jargon 2>/dev/null $term`;

$next=explode("Next: ",$jargon); $next=explode(",",$next[1]); $next=$next[0];
