I finally managed to migrate!
This time I removed the old repositories and added a project on github.
I finally managed to migrate!
After "compiling" the scheme init and rep code into String constants, the Interpreter is now available as a single file. There are two main methods in there: MScheme.Main which runs on the console using stdin and stdout and MScheme.AwtMain, which uses the AWT classes to provide it's own console in a window. An applet class is in there, too.
You can try it at http://mscheme.sourceforge.net/MScheme.html.
But I only tested it on Netscape 4.? with Java 1.1.5.
Up to now, any error caused the interpreter to stop with an ugly java error message. Now such errors are handeled by the code in rep.scm.
