SimCity and Robot Odyssey.
Anyone know the current status of being able to turn an AST tree emitted
by the Python compiler module back into code after it has been modified ?
I think Boxer is an interesting middleground between a full visual
scripting environment, and something more visual than typical Python
source code. It's an old/dead project, and I never was able to actually
get the code to run well (in OS 9 emulation), but the paper is
interesting: http://www.soe.berkeley.edu/boxer/papers.html
In the context of Python, and at its simplest, there would be a
different representation of indentation. Like a box. Which isn't a big
jump for Python, since indentation is already a visual structure for the
code. Then you could add in non-text literals, like a color. These
could be live objects (which I think is how Boxer worked), but that's
not a good fit for Python. A simpler option is just having the idea of,
well, non-text literals. This requires some groking of the code by the
editor (and the entire coding environment, i.e., what binds to what).
But it can be fairly simple, I think, maybe based on some magic methods
attached to types that can have visual source representations.
Anyway, all of that can be serialized to text. Maybe not normal Python
source code, I'm not sure. It could be very close, at least. Anyway,
if I was going to pursue a more visual version of Python that's how I'd
do it. But I'm not going to pursue it, so these choices are left up to
whoever will do that ;)
