stevedore 0.8

stevedore release python

What is stevedore?

Python makes loading code dynamically easy, allowing you to configure and extend your application by discovering and loading extensions ("plugins") at runtime. Many applications implement their own library for doing this, using __import__ or importlib. stevedore avoids creating yet another extension mechanism by building on top of setuptools entry points. The code for managing entry points tends to be repetitive, though, so stevedore provides manager classes for implementing common patterns for using dynamically loaded extensions.

What's New?

• Add name_order parameter to NamedExtensionManager to coerce map() into processing the extensions in the order they are named when the manager is created, instead of the random order they may have been loaded. Contributed by Daniel Rocco.
• Change the NamedDispatchExtensionManager to ignore missing extensions (issue 14).
• Add __getitem__ to ExtensionManager for looking up individual plugins by name (issue 15).
• Start working on the tutorial
• Remove dependency on distribute, now that it is merged back into setuptools 0.7 (issue 19).
