An implementation of NewtonScript
I wrote this in 1997. It got to this point before I got distracted by other things. :) I originally called it "Proto" and got about halfway through changing it to "Prota".
It implements
- The basic NewtonScript object model
- A NewtonScript interpreter (missing floating point and a few other niceties)
- A package stream reader (no writer)
- A printer
It does not implement
- A NewtonScript compiler (I used NTK to compile the initial objects and the interpreter test programs, which is why you'll see NTK files here.)
- An object store
- A UI system
- Any other Newton technology :)
I used the Boehm conservative garbage collection library for memory management
rather than the error-prone RefVar system used for precise GC in the Newton
OS. There might be a nicer way to do this in C++ now, but I haven't written any
serious C++ in this century. :)
This was last compiled in MS Visual C++ in 1997. I have it working on OS X (clang) in 2017. At least, it compiles and does something. :)
BTW, this is pretty close to what the original NewtonScript source code looks like. My style didn't change much in six years.
