XBLinJS 0.4.1 is released. In the unlikely event your browser has SVG support built in, see the SVG Widget demo. Simple, but real.
One of the promises of XBLinJS was that you'd be able to use it for more than just HTML. I have to admit that at the time, I was only about 80% certain that I could do that. But I saw this article, and combined with the recent market successes of Firefox and some personal projects of interest that could be used there, I took a few hours tonight and tried to create an SVG Widget.
I finally have a job, a real job, though I don't start until May 9th. For a while after that I will have an overlap between my real job and my last contract job, but after that, I hope to finally have some time to spend with a clear conscience on my open source projects that I want to work on, especially Iron Lute which has been seriously neglected (though not quite ignored).
During a bit of development downtime here, I've been working on making XBLinJS work on any ol' DOM nodes, not just HTML ones. Which, most notably today, means that you can in theory use XBLinJS as a drop-in replacement for the actual, factual XBL. It also means it can be used with other document structures that use DOM and the same basic event structure, like perhaps SVG someday. If we're extra good developers, we may someday see widgets that successfully integrate both XUL and SVG at the same time.
I've released XBLinJS 0.2, which includes some example widgets and much better documentation.
