Subject: Re: [Tutor] listing classes
To: Kent Johnson <[EMAIL PROTECTED]>
I'm building a light html serialize tool, it's going to be used to
build templates on the fly for ToscaWidgets. I have it already
working, but i'm traying to make a "user friendly" way to declare Tags
and Documents. ( that with some other facilities )
So the idea of the class containing classes, it's just with that end.
Syntactic sugar let's say.
The problem comes because i need to keep the order of the HTML tags,
and as you say dict doesn't work like that.. I've working on this
metaclass, and then extend list with it, but i have the same problem,
the dct comes in a dict...
class MetaHTML(type):
def __new__(meta, name , bases, dct):
# Deletes methods and attributes containing "_"
items = []
for key, value in dct.items():
if '_' in key:
dct.pop(key)
items = [tag() for tag in dct.values()]
def __init__(self, items=items):
self.extend(items)
dct.update({'__slots__':[], '__init__':__init__})
return type.__new__(meta,name,bases,dct)
class HTML(list):
__metaclass__ = MetaHTML
I'm write this metaclass inspired in the WidgetsList that comes
shipped with toscawidgets.
I can do definitely the same using a list and just doing:
document = [A(),
B()]
But it's not so nice.
Any suggestion ?
Thanks
