[Pythoncard-users] py2exe minimal PythonCard app build success

I think py2exe gets very confused by how the PythonCard apps load or rather
the extra files it loads during initialization. The good news is that after
changing the paths to the config file (pythoncard.config.py) and spec file
(spec.py) I got a working .exe. So, given a slightly modified version of the
framework, it is possible to build standalone PythonCardPrototype apps on
Windows. Sweet! Details follow...

I tried it with the minimal sample. py2exe ended up including tcl, due to
the PIL import in graphic.py. If PIL isn't available, then tcl and PIL are
skipped. I'm not entirely sure which names to specify with the -e option to
exclude tcl and/or PIL, so I just commented out the imports and set
PIL_FOUND = 0 in graphic.py. Of course, if your app used PIL, you would want
it included, so the question is then whether you need tcl?

I used the this command-line to build minimal:
  python setup.py py2exe

Here's the setup.py script:

from distutils.core import setup
import py2exe

setup( name = "minimal",
       scripts = ["minimal.py"]
       )

The resulting output files in dist\minimal with file sizes in bytes:
    57344 Jul 26 12:40 PyWinTypes21.dll
    49236 Jul 26 12:39 _sre.pyd
   477563 Nov  9 19:08 minimal.exe
   708696 Jul 26 12:38 python21.dll
   364544 Jul 10 13:39 stc_c.pyd
   147456 Jul 10 13:36 utilsc.pyd
    57439 Jul 26 12:46 win32api.pyd
  2080256 Jul  6 12:37 wx23_1.dll
  1576960 Jul 10 13:35 wxc.pyd


The two changes necessary in the current framework to do a build were:
config.py, line 25, change how the 'pythoncard.config.py' or
'pythoncard.user.config.py' is loaded
changed:
            #basePath = os.path.dirname( os.path.abspath( __file__ ) )
to:
            basePath = ""


res.py, line 40, change loading of spec.py
changed:
            #specPath = os.path.join( thisDir, 'spec.py' )
to:
            specPath = "spec.py"

These changes were against release 0.5, which is the same as what's in cvs.
I then copied the spec.py and pythoncard.config.py files to the minimal.py
directory so they would be found while the .exe was being built.

minimal.py, lines 20 and 21, hard-coded the resource file name
    #base, ext = os.path.splitext(sys.argv[0])
    #filename = base + ".rsrc.py"
    filename = "minimal.rsrc.py"

Normally, spec.py and pythoncard.config.py are in the package directory.
Maybe Thomas will has some suggestions on dealing with path issues like
this? I'm pretty sure the abspath() call was added for finding the files
because we had trouble with file loading under Linux when you didn't run a
sample from the package directory. I skipped trying to fix some of the paths
in model.py for loading the pycrustrc.py files, so that could probably use
some work to.

Finally, I didn't attempt to comment out PyCrust, so the app I ended up
building can still show all the debug windows, which would be needed for
something like the turtle sample.

Go to wxPython/samples/doodle, run "python setup.py py2exe -w" and then look
for superdoodle.exe under the dist folder.

It's an extremely simple example, so some other py2exe or distutils work may
have to be done to get it right for a PythonCard app, but it shouldn't be
too difficult.
