[SOLVED] How can I reload pserve when a template changes?

How can I reload pserve when a template changes?

I have pserve --reload working with any python changes, but I still have to manually reload when I change a template.

I made this little script that monitors my templates folder for any changes, but what is the command to reload pserve? If I need to call a pserve method from within my Pyramids project, like in init.py or something, what is the method I would call to reload pserve?

#!/usr/bin/env python
import sys
import pyinotify
from subprocess import call
import time

wm = pyinotify.WatchManager()
mask = pyinotify.IN_DELETE | pyinotify.IN_CREATE | pyinotify.IN_MODIFY

class EventHandler(pyinotify.ProcessEvent):
    def process_IN_MODIFY(self, event):
        print "Modified: ", event.pathname

        # This is where my reload call would go...            
        # call(["pserve", "reload"])

handler = EventHandler()
notifier = pyinotify.Notifier(wm, handler)
wdd = wm.add_watch("/path/to/my/pyramid/templates/", mask, rec=True, auto_add=True)

notifier.loop()

Solution

Pyramid already provides a method to reload templates without restarting pserve by putting such configuration in a PasteDeploy development.ini file or using environment variables. See Environment Variables and .ini File Settings. Of course, do not enable template reloading in production as it slows down your application.
