I'm creating a python addon for ArcMap, one of the programs I use heavily for my major. The purpose of the script is to autosave the document periodically in the event of a hang or crash (which is somewhat common since the program deals with extremely large map files and datasets). In any event, I've pieced together the script, but my knowledge of coding is limited to lua and even then I'm not that great. If somebody who knows python could look this over and give me some pointers on the syntax, I would be very grateful.

Hidden/Spoiler:

[code]import arcpy

import pythonaddins

class Autosave(object):

    """Implementation for Scripts_addin.extension2 (Extension)"""

    def __init__(self):

        # For performance considerations, please remove all unused methods in this class.

        self.enabled = True

    def startup(self):

        pass

    def mapsChanged(self):

        pass

    def saver():

	mxd = arcpy.mapping.MapDocument("CURRENT") #targets the currently open map for saving

	mxd.save() #actually does the save

	print "saved successfully" #and maybe a timestamp?  But anyway 

    t = Timer(120.0, saver) #seems wrong syntax

    if mapsChanged(): #is that proper syntax?  We'll soon find out.

		t.start() #after 120 seconds, the map will be saved.  This can be changed depending on how long you want.

	else:

		return

[/code]

PS - This is not a project for class, its just my attempt at making a utility that has some practical use. Thanks for reading!

You're missing

import threading
import time

Timer is a threading object.
