py2exe

Jens,

I did it by dinamic loading the pyc files in my code. The problem with th=
is
approach is that at least one file will be a plain vanilla source code fi=
le
with the idea of also having it has a "plugin", so it might work 4 u as w=
ell.

You can check it out since it is Open Source project anyway stored at
http://file-spector.sourceforge.net

In the setup.py I load it using a glob instruction:

...
     data_files =3D [("images", ["images/file-spector.ico",
			    "images/add-arrow.bmp",
			    "images/add-node.bmp",
			    "images/subtract.bmp",
			    "images/struct-a-file.gif",
			    "images/export.bmp",
			    "images/new.bmp",
			    "images/open.bmp",
			    "images/save.bmp"]),
			    ("pool", glob.glob("pool/*.pyc")) ],
...

In the code, all files in the pool directory, which is actually
a package since it includes a file named __init__.py, are loaded
when needed for the first time using the import. You can check it
out in the class DataNodeVisitor in the DatNode module file.

http://cvs.sourceforge.net/viewcvs.py/file-spector/prototype/saf/

Still, Heller might have a better and absolute solution for it.

There's a patch here

<http://sourceforge.net/tracker/index.php?func=detail&aid=952891&group_id=15583&atid=315583>

which has been applied to CVS, but this is not yet released.

i implemented the changes from the patch link into the build_exe.py. but th=
e
modules ImportError still exist.
i am using python 2.2.3 with wxpython 2.4.2.4 and py2exe 0.40.

Does the patch work with this versions or is it my mistake???

If your pyc-files originally located in ./plugins/ directory
try puts them into produced by py2exe library.zip -- in subfolder inside 
of zip: library.zip/plugins/

Jens, I misread your original question - sorry for that.
You don't need that patch, it should work with the current version of
py2exe - the only thing is that you need to make sure that the
directory where your .pyc files are must be on sys.path. In the
exe-file, the only entry in sys.path is the full path of the library.zip
file.

HTH,

Thomas

Hi,

i tried it out with python 2.3 and py2exe 0.5.3 and the import of pyc-files=

worked fine.
my problem is now, i have some pyc files that are compiled with python 2.2.=

i dont have the source code for these files. to import python2.2 pyc-files
with python 2.3 is not possible (bad magic number....). thats why i need to=

import pyc files within python 2.2 and py2exe 0.4.0, but there i got this
ImportError.

here is my little test environment:

=3D=3D=3D=3D=3D=3D=3D=3D=3Dfile func.py
def f(a):
    return a*a
=3D=3D=3D=3D=3D=3D=3D=3D=3Dend of file: func.py


=3D=3D=3D=3D=3D=3D=3D=3D=3Dfile test.py
import func
print func.f(10)
=3D=3D=3D=3D=3D=3D=3D=3D=3Dend of file: test.py


=3D=3D=3D=3D=3D=3D=3D=3D=3Dfile setup.py
from distutils.core import setup
import py2exe

setup(name=3D"Test",
  version=3D"1.0",
  scripts=3D["test.py"])
=3D=3D=3D=3D=3D=3D=3D=3D=3Dend of file: setup.py



i compiled the setup.py and got the test.exe. then i copy func.py into the
directory that contains test.exe.
run test.exe and got the expected print out "100" (10*10)
after this run i have the func.pyc

now i delete func.py (i just have the 3 files test.exe, python22.dll and
func.pyc)
run test.exe and got:
Traceback (most recent call last):
  File "<string>", line 3, in ?
  File "imputil.pyc", line 106, in _import_hook
ImportError: No module named func


for python2.3 i added the following 2 lines to test.py (because of sys.path=

is library.zip) and it works
import sys,os
sys.path.append(os.getcwd())


any ideas??

best regards
Jens

One (convoluted) solution is to track down 'decompyle' (it can still be
found...). This will convert python 2.2 .pyc files back into python sourc=
e
code. There isn't a public version for 2.3 unfortunately.

Fuzzy

It seems imputil doesn't handle .pyc files.  You may be able to fix this
by hacking imputil and/or py2exe yourself.

Hi,

sorry for annoying you again, but its hard to get into the code. i tried to=

modify the py2exe0.53 code to run with python2.2. the result was an empty
library.zip and no exe file.
so i tried to hack the imputil.py, but still looking for the code, that
handles the import of modules (at runtime of the exe file).
i tried to modify the constructor of the ImportManager class.
self.add_suffix(".pyc", py_suffix_importer) -> i thought i have to register=

the pyc file extension. added some print instructions in the
py_suffix_importer method, but i cant see any changes.
Is there any hint you can give?

Jens

I'm afraid I cannot give too much help, but I'll try my best.

That won't work - python2.2 doesn't have the zipimport feature needed by
the exe.

The imported code is in lib\site-packages\py2exe\support.py.

I would first try to get it to work in pure Python.
The imputil module has a _test_revamp() function, this (IIRC) replaces
the normal import mechanism by the one from imputil.

Trying that out (in the interactive interpreter), I'm able to import
an x.py module, but not the x.pyc file when I have deleted the x.py
file - I get an import error.

c:\>py22
Python 2.2.3 (#42, May 30 2003, 18:12:08) [MSC 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import imputil
>>> imputil._test_revamp()
>>> import x
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "c:\python22\lib\imputil.py", line 106, in _import_hook
    raise ImportError, 'No module named ' + fqname
ImportError: No module named x
>>> ^Z

I hope that gives you at least an idea where start,

Thomas
