I'm trying to make Squishdot work with INSTANCE_HOME nicely. However, the testing is going wrong on a normal Win32 Install...
I had lots of lines that went something like:
f=open('%s/Products/%s.dtml' % (SOFTWARE_HOME,file))
Which generates:
E:\Zope\2.2.0\lib\python/Products/Squishdot/validArticle.dtml
That's not very nice in itself but seems to work with Python's open...
However, when I change them all to be like, for example:
f=open('%s/Products/%s.dtml' % (INSTANCE_HOME,file))
I then get:
'E:\\Zope\\2.2.0/Products/Squishdot/validArticle.dtml'
This looks correct to me. If no explicit INSTANCE_HOME is set, it defaults to SOFTWARE_HOME minus '/lib/python'. On the other hand, I wonder why you're constructing '%s/Products/' paths explicitly like this. If this code is inside the Product to which you would like the path, the proper way to get the path is: from Globals import package_home path = package_home(globals()) # path now probably equals 'E:\\Zope\\2.2.0\\lib\\python\\Products\\Squishdot' in your example. I have no idea if or where this is documented, sadly. I'll definitely put it in my 'writing INSTANCE_HOME-friendly Products' howto, as soon as I get around to writing such a thing :-/ Or perhaps you could? ;-) Cheers, Evan @ digicool & 4-am
