Using GraphApp with Python

Can GraphApp be used with Python?

Yes, there is a Python module for GraphApp, but it has a few problems at the moment. Basically, it is difficult to detect errors inside Python call-backs. But the system is workable.

How do you set up the Python module?

There are a few steps to follow:

1. Firstly, make sure Python 1.3 or later is installed on your machine.
2. Download and install GraphApp for Athena or Motif.
3. Download GraphApp for Python.
4. You'll have to edit the Makefile to point it to your Python installation.
5. Make the GraphApp for Python module and put it in the same place as your other GraphApp libraries.
6. Set your PYTHONPATH environment variable to point to where the GraphApp for Python module is located.

This last point is very important. Without the PYTHONPATH environment variable, Python has no way of making sense of the statement "import graphapp".
