ZCA Configuration

Tools that leverage SPARC packages are usually also dependant on Zope Component Architecture (http://docs.zope.org/zope.component/narr.html). Use of ZCA requires component configuration,which SPARC does via ZCML (https://github.com/zopefoundation/zope.component/blob/master/docs/zcml.rst).

Among other things, sparc.common provides access to Configure(), an easy function that can be used to configure dependant applications.

### Usage - ZCA configuration

This simplifies your ability to create components via ZCML and have your application parse the ZCML files to allow them to be registered for lookup. >>> import a.package.that.contains.a.configure.zcml >>> import another.package.that.contains.a.configure.zcml >>> from sparc.common import Configure >>> Configure([your.package.that.contains.a.configure.zcml, … another.package.that.contains.a.configure.zcml])

You will now have access to components configured within those packages.

### Usage - Retrieve user feedback from CLI application

This simplifies the process of getting feedback for processing within a CLI application. >>> import sparc.common >>> from sparc.common import Configure >>> from sparc.common import ICallable >>> from zope.component import getUtility >>> Configure([sparc.common]) >>> asker = getUtiliy(ICallable, ‘sparc.common.ask_question’) >>> answer = asker(u”How are you?”, required = True, answers = … {‘1’:’awesome’,’2’:’ok’,’3’:’not so good’}, tries = 3) How are you? (1) awesome (2) ok (3) not so good

>>> print answer
'1'
