Simple application configuration system

Project Description


This package provides a method to configure an application via standard .ini files. This is convenient for site admins since they are more likely to be familiar with ini files than with ZCML.

Creating config files

There are two ways to tell a Zope instance which configuration files to load: zcml statements and the APPCONFIG environment variable. zcml statements are processed first, making it possible to override standard configuration.

The zcml syntax looks like this:

<configure xmlns="">
  <include package="z3c.appconfig" file="meta.zcml"/>
  <appconfig file="default.ini" />

This will load the contents of default.ini and merge it into the application configuration.

If an APPCONFIG environment variable is set and points to a file its contents will be merged into the application configuration. This is done last, allowing you to override application defined defaults. For example:

$ APPCONFIG=etc/mysite.ini bin/instance fg

Accessing configuration

The configuration data can be accessed from your code via a IAppConfig utility. This utility is essentially a standard python dictionary which stores all configuration data. For example lets use a very simple configuration file:

title = My lovely site

You can access the title from python with code like this:

from zope.component import getUtility
from z3c.appconfig.interfaces import IAppConfig

print "Site title is: %s" % appconfig["site"]["title"]

Utility methods

As a convenience a utility method is provided to convert values from a configuration file to booleans: the z3c.appconfig.utils.asBool method:

from z3c.appconfig.utils import asBool
print "Pants are on: %s" % asBool("true")
