NAPYR is an acronym for "Not a Python runtime". Well, it isn't, but it comes close.
If you are a end-user: it is a setup of common python DLLs to a special folder on your system, which defaults to %Program Files%\NAPYR. You need to have NAPYR installed to use a NAPYR-enabled application.
If you are a developer: it is a setup of common python DLLs, so you don't need to package them in your installer.
It includes the python runtime DLL, the win32all runtime DLLs and wxPython runtime DLLs. It comes with a nice installer, and an uninstaller, courtesy of the fine NSIS.
NAPYR currently runs only on Windows NT/Windows 2000/Windows XP. It does NOT run on Windows 95/Windows 98/Windows ME.
You can download the single-file installer here. You can also download the source separately, here.
This setup contains parts covered by different licenses. Man, do I hate that lawyer stuff! Anyway, here we go:
Python is copyrighted by the Python License.
The Win32all Extensions are copyrighted by Marc Hammond.
wxWindows is copyrighted by wxwindows.org, and, to everyones surprise, wxPython is copyrighted by wxpython.org.
py2exe is copyrighted by Thomas Heller.
My own code - which accounts for not much in this package - is freeware. Enjoy!
Nothing, really. All you have to do is install NAPYR, if you want to use a NAPYR-enabled application.
NAPYR uses a patched version of py2exe to do its magic. Its not very impressing magic, granted, but it works. The McMillan Installer is currently not supported. OK, how does it work?
You must have py2exe installed, version 0.4.1. (Otherwise, you might have to finetune the patch described below).
Download and extract the NAPYR source.
Copy py2exe-patch/support.py to your \python22\Lib\site-packages\py2exe\support.py. See a description of the patch below
Recompile with the updated py2exe distutils. You can now safely remove the files from your setup that are already part of NAPYR.
The patch is simple, really. If the .pyd cannot be found in the local directory, the environment variable NAPYR_PATH is looked up. It must point to a directory where the .pyd can be found. I told you it was simple, didn't I? But you want the details, so here we go: the original code has this line:
# Should catch IOError and convert into ImportError ??
fp = open(pathname, desc[1])
which will be replaced by this block:
fp = None
try:
fp = open(pathname, desc[1])
except IOError:
import nt
pathname = "%s\\%s" % (nt.environ["NAPYR_PATH"], oldpathname)
fp = open(pathname, desc[1])
dict['__file__'] = pathname
return 0, imp.load_module(fqname, fp, pathname, desc), dict
Because I don't want to modify the path on Windows 9x - that involves patching the autoexec.bat, which I don't have enough willpower to do.
