    Figlet Extension

    Integrate figlet text into wiki pages using figletlink in a custom Mediawiki extension:

    Syntax[edit]

    <figlet>text</figlet> (default font=standard)

    <figlet font=fontname>text</figlet> (set another font)

    <figlet>$fonts</figlet> (show font list)

    <figlet font=$self>$self</figlet> (special for template usage, $self=pagename)

    Example[edit]

    <figlet>moo</figlet>

    <figlet>moo</figlet>

    Result[edit]

    <figlet font=digital>moo</figlet>


    Example[edit]

    <figlet>$fonts</figlet>

    Result[edit]

    <figlet>$fonts</figlet>


    For all fonts also see Category:Figlet

    Source[edit]

    Historic: The original idea by DrOwl: "this is a first untested version with just monkey knolage of how to make it work"

    <highlightSyntax> <?php

    1. Figlet Mediawiki extension
    2. using shell figlet
    3. by DrOwl 21.06.2005 modded from
    4. by mutante 25.03.2005
    5. modded again 21.05.2005 ,mutante
    6. modded again Owl & mutante 20.06.2006 - the slightly more secure 23 line version

    $wgExtensionFunctions[] = "wfFigletExtension";

    1. extension hook callback function

    function wfFigletExtension() { global $wgParser;

    1. install parser hook for <figlet> tags

    $wgParser->setHook( "figlet", "renderFiglet" ); } function renderFiglet( $input ) { global $wgOutputEncoding; $input = mysql_escape_string($input);

    $output="
    ";
    $output.=shell_exec("figlet " . escapeshellarg($input));
    $output.="
    ";

    return $output; } ?> </highlightSyntax>
