Hooking zope.component to any python project
Zope Component Architecture is a set of libraries used for aiding in writing component based applications using python. It provides some useful libraries to handle common patterns such as factory, adapter, multiadapter, and subscribers.
In Inigo, we utilizes Zope Component Architecture widely in our development process as it helps us in decoupling components in our system.
Anyway, lets get straight to the point of this post. Basically, what I'll go through in this post would be one method of hooking zope.component together with a configure.zcml into your current python project. It might not be the best way, but the simplest that I know of.
Requirements
Setting up
In your project egg module directory, create a file called
This file will be the starting point for your project's component registration
Loading configure.zcml
In your python project, probably right at the start of the main() function, add this:
Thats it, and you now can use ZCA in your app like you do in Zope.

Requirements
- You'll need to have these installed in your python environment:
zope.component, zope.configuration. - Your project is packaged as an egg (probably possible if not as an egg, but I never tried that)
Setting up
In your project egg module directory, create a file called
configure.zcml with this content:<configure xmlns="http://namespaces.zope.org/zope">
</configure>
This file will be the starting point for your project's component registration
Loading configure.zcml
In your python project, probably right at the start of the main() function, add this:
from zope.configuration.xmlconfig import xmlconfig
from StringIO import StringIO
xmlconfig(StringIO('''
<configure xmlns="http://namespaces.zope.org/zope">
<include package="your.project.egg.module"/>
</configure>'''))
Thats it, and you now can use ZCA in your app like you do in Zope.
