I'm working on three things. Bad news first.
1. I've been looking into dojo.storage. I really want the ability to load/save files, but it's been very frustrating so far. Dojo is the opposite of CodePress: big, complicated, hard to debug. And it needs debugging, because it doesn't work.
2. Work on the new, faster macro-expander (by compiling psyntax.pp to JS) continues apace. There were technical difficulties last week, so some debugging remains to be done.
3. Now the fun part. CodePress (http://codepress.org/) is a little programmer's editor, written in JavaScript, that runs in your browser. Amazingly nice. The architecture is simple and sweet. Adding Scheme syntax highlighting was a breeze. Adding parens matching was slightly more work, and just now I only have it working for Gecko-based browsers (Mozilla). No indentation yet. The next step is to integrate it with the Try Scheme demo page and go live with it; parens matching for MSIE and other browsers should follow, but I need to get in touch with the CodePress guys and see what they think about it all.
