Figlet Extension

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

Syntax

<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

<figlet font=23>moo</figlet>

example Result

| '_ ` _ \ / _ \ / _ \ 
| | | | | | (_) | (_) |
|_| |_| |_|\___/ \___/ 

test Result

<figlet font=`cat /etc/passwd`>`cat /etc/passwd`</figlet>

(not installed on anything this is only beta i dont have figlet installed on this server)
