Hi
win98, Py234, wxPy2515
I take a look at your project. If I undestand correctly, wxPRE
(wx Python Running Environment ???) is a runtime machine to run
Python scripts using wx without having Python and/or wxPython on
the user's platform. The goal is an easy deployment of wxPy
applications.
I only downloaded the script file and start testing.
1) Running wxPRE.py from the DOS prompt works fine.
python wxPRE.py application.py
2) May I suggest the .pth files may contains more than
one lines? See my version.
3) Thinks became more complicated when I created an
wxPRE.exe. wxPRE.exe -because it is frozen- does not
recognize its own path. Therefore it can not find the
.pth files. This is the main reason, why I started to
code my own test script. See my version.
4) Please add a coding info in the Pyhton script.
All users are not american.
o My test version (of course, the project is yours)
See code below. This basic version assumes only one
multiline .pth in the wxPRE directory.
o Creation of wxrun.exe
With py2exe
o Test of wxrun.exe
- In the wxrun.exe dir, I have a single .pth file
- Copy ..\site-packages\wx\*.* to c:\wx. I removed
all subdirs except \lib.
- c:\ is in my .pth file
- I renamed c:\python23 to c:\python23xxx
- Start playing with wxrun.exe from different dirs
having small.py in different test dirs.
- It works fine. (I have some problems with applications
searching for some files in their own homedir).
o small.py
A small application displaying the sys.path
o Open questions / proposals / comments
- It seems such a runtime machine is feasible.
- Should the runtime machine contains the wx part
only or also python?
- Vesioning? A runtime application for every wxPython/Python
couple version or a machine that tests Py/wxPy version.
- Ability to include/add .pth files and/or paths at the prompt.
- An application should be able to be run from the run time
machine and as a "normal way" without modifications.
- What should the distribution contain, dll, pyd, ...
Q. to Robin Dunn.
o My test scripts are below

but the file is actually 7-bit ASCII which is assumed by Python if no encoding is specified.
