Have a look at: syntaxhighlighter space [1]
The status is erxperimental, because, if you use expert mode (disabled
by default) a vanilla tw can't render the new code. So, there is no
fallback yet. If you use the default configuration everything should
be fine.
I did test the basics. But any feedback would be welcome.
And it would be interesting if you describe your usecase. Which
languages (brushes), do you want to highlight.
text, css, js, xml are included by default.
to use it, import all tiddlers tagged "syntax" or include
syntaxhighlighter space into your space.
