I haven't read up on JScheme much yet, so I'm not seeing an easy way to test this. From the looks of it, the Scheme isn't actually being invoked at the moment in that code. But, it looks like it gets past all of the security checks in the AppletViewer even when I call initScheme() from init(). So, it looks like this might have possibilities of making unsigned applets.

The code I've been working on is here: http://automatous-monk.cvs.sourceforge.net/viewvc/automatous-monk/APictureLanguage/ but it's not really organized. I'm doing exercises from <i>The Wizard Book</i>. (That's why the files are named after exercises.) I plan on finishing this, organizing and cleaning it up. I may do this for the study group.

Spiffy. Yes, as I’d been thinking about it, I was struggling to come up with a good way to do formulas without lambdas. Spiffy.

There's also a test suite and simple documentation (the code was written in a literate programming style, using ctangle/cweave). Everything took 900 LOC with comments, documentation and empty lines. Lisp Cells are collected in classes that group them. My cells were simple independent variables. I found this way simpler and easier to do using C++ templates. I did all of this for my OOP class a year ago, and I considered releasing it as free software, but somehow I did not find time for that... but I still want to. I also planned to integrate them with gtkmm, but this would be pretty time-consuming. The main problem was that C++ does not have closures and lambdas (boost lambdas are very weak). I tried to use macros to make defining cells easier, but I found no solution I liked. Now I'd probably try to use OpenC++ for that.

I had never heard of them before, but I have now watched that video and read a few tutorials and tangential posts. I think they may suffice for the purposes of my study group assignments. That will give me a good chance to feel them out. I may have to bend them a little bit to really work with Lisp, but it should be fun. Thank you. I'm sure that I'll blog more about it here as I try them in practice. They are of interest.

Does this mean you finished them? I am interested in hearing how that went, what obstacles C++ presented, etc. You said were implementing. Does this mean you finished them?

AFAIK Adobe also does a similar thing for their software (there was a google techtalk about that some time ago). I really think something like this should be standard.
