In my previous post, we saw how to extend wallaby by writing Ruby classes that use a client library to extend the wallaby shell. If you're comfortable with Ruby, this is a great way to build functionality on top of the wallaby API in an idiomatic way. However, Python programmers shouldn't have to learn Ruby just to interact with wallaby.
The wallaby source repository now includes a Python client library to interact with a wallaby service. This library does a few things to make your life easier:
- Raw QMF object proxies are wrapped in Python client objects.
- Object references returned by QMF methods are automatically wrapped by client objects.
- QMF methods that return error statuses will raise exceptions in the client library.
- Client classes include docstrings for QMF methods.
See below for a transcript illustrating these features. Note that you'll need to have the following packages installed to use the Python wallaby client library: Red Hat Enterprise MRG 1.3 (or the
python-qmf package from a recent Fedora release) and Wallaby 0.9.18 or later (0.10.0 to access all of the features exposed through the client library).
