PyCLP 0.7

Interface to ECLiPSe CLP

Package Documentation

Latest Version: 0.8

Introduction

PyCLP is a Python library to interface ECLiPSe Constraint Programmig System.

This module try to implement a pythonic interface to ECLiPSe (alias easy to use) by compromising on a little bit on performance.

Major differences from ECLiPSe standard interface libraries

The main difference compared to embedded interface provided by ECLiPSe system is the persistence of constructed terms after calling the pyclp.resume (check 3.1.2 Building ECLiPSe terms ) function. In ECLiPSe standard interfaces compound terms are destroyed after resume while in PyCLP are stored in a reference that survives after resuming. PyCLP will destroy the reference only when python destroys the linked python object (garbage collection). This consumes more memory but now the python object and the related ECLiPSe object have the same lifetime.

Moreover, in the definition of the API I tried to take advantage of a common propety of python and ECLiPSe: both are weak typed languages.

Next steps

  • Extend functionality of set_option function

Installation

At this moment only Linux platform is supported.(tested on Ubuntu 12.04).

Linux

In this page it is explained how to compile and install from source in a Linux Platform

Requirments

Following packages shall be preinstalled before proceeding the installation of PyCLP

Download

Download source files from PyCLP sources

Compilation & Installation

Setup Enviromental variables for ECLiPSe:

ECLIPSEDIR enviromental variable shall be set to the folder where is located ECLiPSe system. This is required for compiling and using PyCLP.

LD_LIBRARY_PATH enviromental variable shall contains the path of folder that contains the ECLiPSe sharable library. E.g. <eclipsedir>/lib/<platform>.

Install using usual method

sudo python setup.py install

Regression test

python test.py

Tested enviroment

The present version of pyclp is tested on

  • Ubuntu 12.04 LTS (32bit), Python 2.7 and 3.3
  • Ubuntu 13.04 (64bit) , Python 2.7 and 3.3

However it is expected working on other platform that fullfill the requirements.

Windows
