Allows a component to state dependencies on other plugins
ComponentDependencyPlugin allows a Component to state a dependency on other plugin, via the IRequireComponents interface:
class IRequireComponents(Interface): def requires(): """list of component classes that this component depends on"""
The Component classes that are returned by the requires method will be enabled upon environment upgrade. This allows very simple dependencies. Of course, for installation, the required components are still required to be part of python (in install_requires in setup.py) and this plugin will not work if there is trouble loading a plugin that is required.
If you have any issues, create a new ticket.
Download the zipped source from [download:componentdependencyplugin here].
The files in test.py illustrate how to use the plugin. Enable the ComponentDependencyPlugin (componentdependencies.componentdependency.componentdependencyplugin = enabled) and enable the TestDependencyPlugin (componentdependencies.test.testdependencyplugin = enabled). Trac will then require an upgrade. The FooBarTest component will be enabled in the upgrade.
