******************************************************************zope.configuration extensions to filter out unwanted configuration******************************************************************.. contents::CHANGES*******1.2.0 (2017-04-17)------------------- Added ``MANIFEST.in``.- Using Python's ``doctest`` module instead of depreacted``zope.testing.doctest``.1.1 (2009-02-26)----------------- Move the ``exclude`` directive into the original ``zope.configuration``package.So, this package is currently contains only a backward-compatibilityimport for ``exclude`` directive and is not useful anymore. Howeverit's intended to contain miscellaneous extensions to the configurationframework and may contain more in future, so we are not marking isas deprecated for now.1.0 (2007-09-29)----------------Initial release.Detailed Documentation**********************Configuration Extensions for Filtering or Inhibiting Configuration==================================================================The zc.configuration package used to provide the ``exclude`` directivefor inhibiting configuration. It was included in the zope.configurationand this package currently provides a backward-compatibility importsand tests that ensure that it will work for people who are alreadyusing zc.configuration and not the newer zope.configuration.This package may contain more configuration extensions in future, butcurrently, it's not useful anymore as the only feature it provided,the ``exclude`` directive was merged into the original``zope.configuration`` package.First, let's look at an example.  The zc.configuration.demo packagehas a ZCML configuration that includes some other configuration files.We'll set a log handler so we can see what's going on:>>> import logging, sys>>> logger = logging.getLogger('config')>>> oldlevel = logger.level>>> logger.setLevel(logging.DEBUG)>>> handler = logging.StreamHandler(sys.stdout)>>> logger.addHandler(handler)Now, we'll include the zc.configuration.demo config:>>> from zope.configuration import xmlconfig>>> _ = xmlconfig.string('<include package="zc.configuration.demo" />')include /zc.configuration/src/zc/configuration/demo/configure.zcmlinclude /zc.configuration/src/zc/configuration/demo/sub/configure.zcmlinclude /zc.configuration/src/zc/configuration/demo/spam.zcmlEach run of the configuration machinery runs with fresh state, sorerunning gives the same thing:>>> _ = xmlconfig.string('<include package="zc.configuration.demo" />')include /zc.configuration/src/zc/configuration/demo/configure.zcmlinclude /zc.configuration/src/zc/configuration/demo/sub/configure.zcmlinclude /zc.configuration/src/zc/configuration/demo/spam.zcmlNow, we'll load the zc.configuration meta.zcml and use the excludedirective to exclude the two files included by the configuration filein zc.configuration.demo:>>> _ = xmlconfig.string(... '''... <configure  xmlns="http://namespaces.zope.org/zope">...   <include package="zc.configuration" file="meta.zcml" />...   <exclude package="zc.configuration.demo.sub" />...   <exclude package="zc.configuration.demo" file="spam.zcml" />...   <include package="zc.configuration.demo" />... </configure>... ''')include /zc.configuration/src/zc/configuration/meta.zcmlinclude /zc.configuration/src/zc/configuration/demo/configure.zcml.. cleanup>>> logger.setLevel(oldlevel)>>> logger.removeHandler(handler)Download********
