Baby Steps

So Pjotr recommended that I back up, and try to use SWIG on tiny bits of the code. At the same time, I realized that having a 35K-line .i file was insane, when "based" off a 300-line .h file (especially when about half of those 300 lines are comments). Xin has been making his own .i files, so I decided that I'd have a go at that.

And then, looking through SWIG docs, I find that that's not even necessary for some very simple .h files. There's a -module option that lets you go directly off of the .h file. So...can't hurt to try it. Here are the results, by header file (in utils). In the cases where it compiled sans error, I just left it blank:

Everything compiled--this were all warnings. Many of them are just inheritance problems. Some are for other classes in utils (e.g. GraphicDevice, Clonable), and others are for standard C++ classes (e.g. string, exception). This should be easy to fix.

What I'm more worried about is the template stuff. Also strange are errors about the [] and = operators. For the former, it talks about using the %template directive in SWIG. That's a good place to start looking.

Finally, I feel like I'm moving forward again.
