[Push] Re: Questions...

[Lee Spector]

Adzni,

There are two versions of the Push3 interpreter, one in Lisp and one  
in C++. You probably just want to use one or the other. The C++  
version is also built into the breve simulation environment, which  
can be obtained from http://www.spiderland.com/breve . If you use  
breve then you don't have to download any of the Lisp or C++ code for  
the interpreter -- it's all include in the breve application. On your  
specific questions:

SwarmEvolve-2.0.tz must be run within breve. It uses breve's  
simulation physics, etc., and there's no version of this for the Lisp  
version of Push or for the non-breve C++ version. SwarmEvolve-2.0.tz   
is steve (breve) code that makes calls to the Push interpreter that  
is built into breve. It is actually included in the breve package as  
one of the demo programs. Follow the instructions in the breve  
documentation for running demos to try it out.

If you look at the PushRegression.tz or PushTest.tz. source code  
files you'll see how to load a configuration file, and if you look at  
the demo configuration files you'll see how to turn on specific  
instructions.

Push was developed for use in systems that produce code  
automatically, primarily through evolution. It was not designed to be  
a language that people would use when they sit down to write programs  
themselves. It could be used for that purpose, but it was designed  
with evolution in mind, not the psychology of human programmers.

You might try working with the PushTest.tz demo file in breve first.  
If you can't get this to work then perhaps you could send me your  
code and I could take a look.

I hope this helps.
