Re: [Pgu-devel] pgu and py2exe -- problem solved

Phil,
Tried that and couldn't find the site, either as svn or http. Anyway, I
finally decided that my only alternative was to spend a few hours running
experiments. You gave me enough information so that I knew what files I
needed (the default folder), and I figured that I could find the right
location for these files by trial and error. I finally got it to work. The
correct command is
shutil.copytree('data/themes/default','dist/default')
This is anything but obvious. I can't believe that I am the only person who
has ever run into this problem, nor can I believe that I'm the only person
with this problem who couldn't just figure it out in a few minutes.
Future pgu users might appreciate having a note of this problem put on the
pgu web page. Something like this:
"Q: I've got a program that uses python, pygame, and pgu, and I want to use
py2exe to make an executable. Everything seems to work until I try to run
the executable, at which point I get an error about some problem with
app.pyc and themes.pyc. What do I do to fix this?
A: Make sure that the data folder from the pgu distribution is in the main
python directory that houses the program file and the setup file. You need
to make two changes to setup.py. First, add the line
import shutil
in the beginning portion, if it isn't already there. This command loads a
utility that copies files. Second, at the bottom of the file, add the line
shutil.copytree('data/themes/default','dist/default')
This command copies all of the files in the data/themes/default directory
tree of the pgu distribution into a new folder called default that is
created in the dist folder along with the executable and other files. This
command only works if you don't already have a dist/default folder; delete
an old version of this folder before running setup.py.
"
Now that I've got my project working, I want to say that I'm very pleased
with my experience of programming with python, pygame, and pgu. The pygame
documentation is first-rate. While I couldn't find everything I wanted in
the pgu documentation, the Pitcher's Duel example taught me what I needed to
know about using pgu to make a gui with a variety of widgets. As a
professional mathematician, I'm great at programming a simulation based on
scientific assumptions, but I lack the programming skills to write
professional code in javascript. A simulation written in software generally
unknown outside of mathematics departments doesn't have adequate
availability for full utilization. Now any user can run my code simply by
downloading a zip file, unpacking the contents, and double-clicking the
executable. When I have more ideas for college-level educational tools,
I'll definitely use the same programming environment.
Best wishes,

Glenn,
I'm having a tough time following all that ... You might want to check out
svn://www.imitationpickles.org/pyweek4/trunk -- it includes a setup.py
script that uses py2exe without any trouble. It manages to copy the gui
data as well.
Thanks!

Phil,
I don't understand your reply.
Do you mean that the C:/Python25/data/themes folder, which came from the pgu
package but is not in a folder named "pgu", needs to be present as
C:/Python25/dist/pgu/data/themes? This seems weird, but I tried it anyway.
I got the same error message.
Do you mean that the data/themes folder included as part of the pgu package
needs to be present as /dist/data/themes? The command
shutil.copytree('data','dist/data')
seems to have done that just fine.
In short, test.py runs fine from C:\Python25 with your pgu stuff in
C:\Python25\pgu and C:\Python25\data, but test.exe does not run from
C:\Python25\dist with exactly the same pgu stuff in C:\Python25\dist\pgu and
C:\Python25\dist\data.
It's weird that nobody else seems to have had a problem using pgu with
py2exe. There are lots of reports on the web of people having trouble with
the fonts in pygame. Surely some people have used pgu with py2exe and yet
there are no reports of problems.

Glenn,
You need to include (from pgu) the data/themes folder.
Hope that helps!

After a necessary break, I'm back to finishing my software project. I'm
still stuck on getting py2exe and pgu to work together. I put together a
test case. I'll be grateful for any help! I probably have made some
obvious mistake, but I just can't see it.
Here is the code for the file test.py.
################################################
import pygame, sys
from pygame.locals import *
from pgu import text, gui
pygame.init()
white = (255, 255, 255)
width = 200
height = 100
def finish():
sys.exit()
# create the display screen
screen = pygame.display.set_mode((200,100))
screen.fill(white)
# create GUI object
pgu = gui.App()
IO = gui.Container(width=200,height=100)
# define widget
quitt = gui.Button("QUIT")
quitt.connect(gui.CLICK, finish)
IO.add(quitt,width/2-25,height/2-10)
# show the display
pgu.init(IO)
pgu.paint(screen)
pygame.display.update()
# handle input events
while True:
for event in pygame.event.get():
if event.type == QUIT: sys.exit()
elif event.type == KEYDOWN and event.key == K_ESCAPE:
sys.exit()
pgu.event(event)
pgu.paint(screen)
pygame.display.update()
################################################
When I double-click on test.py, the file runs correctly.
Here is the code for setup.py.
################################################
# setup.py
from distutils.core import setup
from pgu import text, gui
import py2exe, pygame, sys
import shutil
setup(windows=["test.py"])
shutil.copytree('data','dist/data')
shutil.copytree('pgu','dist/pgu')
################################################
I got a command window and set it to the Python25 directory. Then I entered
python setup.py py2exe
This resulted in a huge output dump in the command window. There are a lot
of lines like
skipping byte-compilation of C:\Python25\pgu\gui\theme.py to
pgu\gui\theme.pyc
Then there are a lot of lines about copying stuff from the pygame folder,
followed by the usual stuff that certain modules appear to be missing and a
list of dll files in system32. I don't think any of this stuff is important
because py2exe works fine when test.py does not use pgu.
After this operation, the new C:\Python25\dist\ folder contains subfolders
called data and pgu, and these appear to be identical to the data and pgu
folders in C:\Python25\.
Finally, when I double-click on C:\Python25\dist\test.exe, I get the
following log:
C:\Python25\dist\library.zip\pgu\gui\theme.py:72: DeprecationWarning:
raising a string exception is deprecated
Traceback (most recent call last):
File "test.py", line 18, in
File "pgu\gui\app.pyc", line 42, in __init__
File "pgu\gui\theme.pyc", line 41, in __init__
File "pgu\gui\theme.pyc", line 49, in _preload
File "pgu\gui\theme.pyc", line 72, in _load
could not find theme default
I checked the directories and there are files
C:\Python25\dist\pgu\gui\theme.pyc and
C:\Python25\dist\library.zip\pgu\gui\theme.pyc, although there is no
C:\Python25\dist\library.zip\pgu\gui\theme.py.
One last bit of information. When I double-click on test.exe, I actually do
get a pygame window of the correct size; however, the window is black and
there is no "Quit" button.
Can anyone diagnose the problem for me? Is there something wrong with the
way I use pgu commands in test.py?
Thanks!
Glenn
