Squeaksource.com swiki formatting ?

SqueakSource doesn’t use a Swiki, which is very large. It uses a TinyWiki object for each project, which does not have any wiki syntax tokens for the <code> tag.

"<newline> : \r? \n | \r ;
<blankLine> : <newline> <newline> ;

<rule> : \_[\ \t]* ;
<header> : \!+ ;
<list> : [\#\-\=] ;

<linkText> : [^\*\r\n] ;
<link> : \* <linkText>+ \* ;
<nonLinkStart> : \*\* | \\ [\#\-\=\!\*] ;

<text> : [^\r\n\*\!\#\-\=\\]+ ;
<any> : . ;”

No bold, italic, pre or code tags.

Off the top of my head, I'd suggest you leave a link and do the work on the Squeak Swiki. Put asterisks around your link.

Or put code between rule tags created by underscores.
