Re: [Cheetahtemplate-discuss] problem with include directive on cheetah 2.4.0

[Uhanov, K. <kir...@in...>]

Probably I found workaround for me.
I made some changes for className from compile procedure. 
I replaced starts underscores in generated class name.

Thanks, James, for your information.

Tyler, this is not windows specific problem. I've reproduced that on Linux too. 
Could I get some workaround for cheetah name generation?

The generated class name starts with 3 underscores.  You can't refer
to such a name from within a method due to private name mangling
(http://docs.python.org/reference/expressions.html#atom-identifiers).
Here's a small bit of Python that shows the problem:

__B = 0
class A():
    def f(self):
        return __B
print A().f()

This looks like it should print "0" but instead you get:
NameError: global name '_A__B' is not defined

There's probably some way around this but it may be better just to
ensure that generated identifiers never start with 2 or more
underscores.
