Interactive PyEPL session

Sometimes, I am interested in exploring some PyEPL feature without writing a whole experiment with setting up subject and all that. I rather like to have an interactive python shell and hack away. Here is the code on how to do that:

from pyepl.locals import *

import os

import shutil



# create an experiment object:

# parse command-line arguments

# & initialize pyepl subsystems

tdir = "/tmp/iPyEPL"

subj = "isubj"

subjdir = os.path.join(tdir,subj)



if not os.path.exists(tdir):

  os.makedirs(tdir)





if os.path.exists(subjdir):

  shutil.rmtree(subjdir)





exp = Experiment(archive=tdir,subject=subj,fullscreen=False)

exp.setBreak()



# load some tracks

vt = VideoTrack("video")

kt = KeyTrack("key")

#at = AudioTrack("audio")



# reset the display to black

vt.clear("black")

vt.updateScreen()



# create a PresentationClock object

# for timing

clk = PresentationClock()

Just copy and paste into your python session and you are ready to explore. Thanks to Per for that!
