Documenting Components

ZConfig includes a docutils directive for documenting components that you create. This directive can function as a Sphinx extension if you include ZConfig.sphinx in the extensions value of your Sphinx configuration:

extensions = [

There is one directive:

.. zconfig:: <package-name>

New in version 3.2.0.

Document the components found in the Python package package-name.

By default, the contents of component.xml will be documented. You can specify the :file: option to choose a different file from that package.

Each component will have its name, type, and default value documented. The description of the component will be rendered as reStructuredText (and so can use directives like py:class: and py:meth: to perform cross references). Any example for the component will be rendered as a pre-formatted block.

All ZConfig components reachable will be documented, in the order in which they are found. Often times, if your component extends other components, this will produce too much documentation (it will document the components you are extending in addition to the unique aspects of your component). You can use the :members: and :excluded-members: options to limit this.

Both of these options take a space-separated list of component names. These options can be used together. When :members: is given, only items that are explicitly named, or that are reachable from such items, are documented. The :excluded-members: option overrides this, causing any such members to be explicitly excluded.

These options are also useful for breaking the description of a component up into multiple distinct sections, with narrative documentation between them. For example, to document the main logger component provided by ZConfig separately from each type of handler ZConfig provides, the document might look like this:

You can configure a logger and logging level with ZConfig:

.. zconfig:: ZConfig.components.logger
    :members: ZConfig.logger.base-logger
    :excluded-members: zconfig.logger.handler

ZConfig supports multiple different types of handlers for a given logger:

.. zconfig:: ZConfig.components.logger
    :members: zconfig.logger.handler
