I've started an application that uses Dolmen, a lightweight CMS built on top of Grok, and I want to be able to "rollup" the megrok.resource files based on the devmode setting that was set in the zope.conf file. After a bit of digging, I came up with this code that tells me the current devmode setting for the running instance:

from zope.app.applicationcontrol.applicationcontrol import applicationController
from zope.app.applicationcontrol.interfaces import IRuntimeInfo

def get_debug_mode():
    """Returns the devmode setting for a running zope instance"""

    rti = IRuntimeInfo(applicationController)
    return rti.getDeveloperMode() == "On"
