Python

Python is the preferred scripting language of the CP2K project.

Self-Testing

All python scripts should support self-testing. This means that they can be invoked with –selftest as its sole argument.

Ideally, a script's self-test consists of an exhaustive suite of unit-test. At the very least, it should not crash or break anything. Even an empty self-test will still reveal syntax and import errors. These errors are the most common ones for Python 3 compatibility.

Once per night all Python executable are self-tested automatically.

Language Versions

All scripts should work with Python 2.7 or later. In particular the script should also work with Python 3.x . Additionally, a small set of essential scripts should work with Python 2.4 as well. Essential scripts are those required for building CP2K plus prettify.py and instantiateTemplates.py.
