Yeah, Mustaha!
Sometimes I think I'm a little stupid, jejejeje, I have in front of my nose
but I don't see it
I was solved the problem adding a y: type expression and then subclass the
PythonExpr with the __init__ method modified to change the expression
Too much difficult to do the job in an acceptable way
BUT!!!
If you go to usr/lib/zope<version>/lib/python/zope/tales/tales.py and change
the 592 and 593:
591 else:
592 type = "standard"
593 expr = expression
to
else:
if expression.find('${') > -1:
type = "python"
expr = "path(path('string:%s'))" % expression
else:
type = "standard"
expr = expression
then you could use expressions like this
path/to/render/${with/some/variable}/and/the/rest/of/the/path
I think it's an acceptable change to the code for the job it does
I don't know if Zope people will introduce this change but I think if not
they will be wrong
But they are absolute free to do what they want to do, don't misunderstand
me, please
