PyREDUCE

This is a (ctypes) Python wrapper for the procedural interface to REDUCE (http://reduce-algebra.com/). The interface is stack based so you can embed REDUCE procedurally into Python, not just as text interface.

There is a really sophisticated embedding of this interface into Pure, an excellent modern-style functional programming language based on term rewriting (http://purelang.bitbucket.org/) . If you want to use REDUCE for productive tasks we suggest to use that one as it is much more suited for symbolic tasks than Python. See also: http://puredocs.bitbucket.org/pure-reduce.html

The file reduce.py is only a low level wrapper with a class hack Expr which shows how to interact between objects. There are many ways to implement high level tasks.

Build

One needs to build the REDUCE procedural (C) interface:

• Get the code from http://sourceforge.net/p/reduce-algebra/code/HEAD/tree/ or svn checkout
• Read trunk/csl/new-embedded/README, make the procedural and reduce-image items to get reduce.img and reduce.lib (or .dll on Windows).
• Adjust the path to reduce.img and reduce.lib in reduce.py
• Do the tests for usage examples.
