prologlib is an ISO Prolog processor written in Python 3. It aims at providing
an open source Prolog implementation that strictly follows the non-free ISO
standard document (ISO/IEC 13211-1), from execution model to builtin predicates
and functors.

Usage:

$ hg clone http://bitbucket.org/gpiancastelli/prologlib/
$ cd prologlib
$ python3.1 toplevel.py

Besides toplevel.py, in the project root you will also find the test.py script,
used to drive the execution of unit/acceptance tests for prologlib. If you run
it without arguments, test.py executes all the tests in the tests subdirectory,
showing results that should include no failures. You will note, however, that
some tests are skipped: typically, they involve some unimplemented feature. You
may also run test.py providing the name of a single test file, to execute only
that set of tests. For example:

$ test.py builtin-predicates
$ [...executing tests in tests/test-builtin-predicates.py...]
$ test.py parser
$ [...executing tests in tests/test-parser.py...]

No real API is provided. If you want to integrate prologlib into Python code,
have a look at how prologlib.ui uses prologlib.core.Engine.

Source code includes some examples of Prolog code, to be found in the
subdirectory examples. Those include classic Prolog benchmarks, stored in their
own subdirectory.

BE WARNED! prologlib is extremely slow. It's unlikely that you will find it to
be suitable for serious (and less serious) work.

prologlib's code is distributed under the BSD license.
