the python way of getting the right path separators is to use 

os.path.join(item1, item2, ...)

Works even for macs ;-)

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

[Zope-dev] is INSTANCE_HOME broken on Win32?

2000-09-11 Thread Chris Withers 

Hello :-)

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'

which is:

- horrible
- wrong
- doesn't work ;-)

Anyway, I'm looking for something like INSTANCE_HOME or SOFTWARE_HOME
that:

- works in an INSTANCE_HOME setup
- works in a non-INSTANCE_HOME setup
- works on both Unix and Windows..

Any ideas?

cheers,

Chris
