Changes in code don't apply (Python)

michizac

I have this problem: I am editing the code in a class of my sketch but the changes are not registered by the sketch neither when I save the sketch nor when I re-run it. The only way to have the changes apply is to reload the entire sketch. Is this a new bug?

It might be related to the oscP5 library. This is the sketch:

add_library('oscP5')

class Listen(OscEventListener):
     def oscEvent(_, m):
        global col, msg
        col = m.arguments()
        print col
        print 'Received oscEvent:', m.addrPattern(), col, m.typetag()

def setup():
    size(400, 400)
    background(255)
    portR = 7407
    oscR = OscP5(this, portR)
    oscR.addListener(Listen())

def draw(): pass 

whenever I edit the Listen class nothing happens unless i reload the sketch

Ok I figured it out. If I don't add the

def stop(): global oscR oscR.dispose()

function at the end, the OscEventListener keeps calling the function that I loaded the first time around. with the dispose() it will reload it each time.

@michizac, don't you remember I've found out that bug in your previous post?: ~:>

AFaIK, defining a function stop() to invoke dispose() wouldn't be necessary at all. :-B
My own example doesn't def any stop() nor invoke dispose() and it works alright: :>

Any smart library would automatically dispose() itself when the program exists after all.
But somehow, due to that bug in Python Mode, it's sorta workaround for when the sketch crashes. :-\"

BtW, no need to use global every time like you did for oscR within stop().
Once any variable exists in globals(), we can access it everywhere w/o global.
Unless we need to assign = something to it. In this case, global is obligatory for that variable. L-)
