[parenscript-devel] Generating HTML in parenscript

Thu Dec 27 01:59:41 UTC 2007

I guess I still haven't gotten the darcs post-apply hook right,
because this morning I pushed out the change that made ps-html work in
both Parenscript and CL. I also decided to get rid of CSS generation
altogether; chief reason being I didn't like the code and didn't want
to rewrite it, secondary reason being that right now it is not a good
idea to futz around with CSS on the client side for performance
reasons (which is why I didn't want to rewrite the code).

The one thing I didn't do was to provide CL-WHO like HTML markup. That
will have to wait a little bit.
