The first thing you do is open the registry for the local computer:

>>> from infi.registry import LocalComputer
>>> local_computer = LocalComputer()

You can browse different registry hives:

>>> local_machine = local_computer.local_machine
>>> current_usrr = local_computer.current_user

You can travel the hive in two ways:

>>> # direct
>>> key = local_machine[r'Software\Microsoft\Windows NT\\CurrentVersion']
>>> # indirect
>>> key = local_machine['Software']['Microsoft']['Windows NT']['CurrentVersion']

Accessing a non-existing key raises KeyError.

The registry values are stored in a dictionary:

>>> key.values_store.keys()[:2]
[u'CurrentVersion',
 u'CurrentBuild']

Updating a value is easy:

>>> from infi.registry import RegistryFactory
>>> factory = RegistryFactory()
>>> new_value = factory.by_value('this is a string')
>>> key.values_store['name'] = new_value

The by_value method guesses the registry value type but the type of the instance. You can define the value type on our own by using factory.by_type method.

This project uses buildout and infi-projector, and git to generate setup.py and version.py. In order to generate these, first get infi-projector:

easy_install infi.projector

and then run in the project directory:

projector devenv build
