If you develope a library or many libraries, than you notice that the import / reload mechanism can slow down the developement. This is because the libraries gets reloaded every time you load your testapp.

My way is to not give every library the reload command for itself and do not give the testapp the reload statement.

I have coded an app to do this. Here you have an example (I am shure that someone who codes a library does know how to use this)

Code:
#! /usr/bin/env python
# -*- Mode: Python -*-
# -*- coding: ascii -*-

nuReload

import lwsdk


import example1
import example2

                    ( "PynuReload", lwsdk.SRVTAG_USERNAME | lwsdk.LANGID_USENGLISH ),

ServerRecord = { lwsdk.CommandSequenceFactory("PythnuReload", nuReload) : ServerTagInfo }
This will open a Dialog with a button for the libs (here the libs "example1" and "example2". By clicking a button, the lib for this button gets reloaded.
To shortly reload all libs, a button "ALL" is included. This button Closes the Dialog after the reloads are done.

I hope this will help someone,
