Hi
I would like to be able to get the inputs that are needed into a
template file programmatically.
For example if we had a template:
=====================
$name has $num marbles in his hand.
=====================
I want to be able to initialise this template and call a method on it
to get the list ['name', 'num']
Is there anything in cheetah which does this?
At present, I am sending a "fake" dictionary into the searchList to do
this. This is coded as.
fake = Generic()
t = Template(file=absFileName, searchList=[fake])
print fake.calledAtts
=========================================
class Generic(object):
""" Generic object can pretend to be a dictionary or a list and
doesn't throw
any errors whatever you call it for """
# def __new__(cls, *args, **kwargs):
# if '_inst' not in vars(cls):
# cls._inst = object.__new__(cls, *args, **kwargs)
# return cls._inst
calledAtts = sets.Set()
def __init__(self, *args, **kwargs):
pass
def __call__(self, *args, **kwargs):
return self
def __repr__(self):
return "Generic"
def __nonzero__(self):
return True
def __getattr__(self, name):
return self
__delattr__ = __getattr__
def __setattr__(self, name, value):
return self
def __len__(self):
return 1
def __iter__(self):
return iter(("Generic",))
def __getitem__(self, i):
if isinstance(i,types.StringType):
self.calledAtts.add(str(i))
return self
def __setitem__(self, i, v):
return self
def __contains__(self, itemName):
print "contains " + itemName
return True
def has_key(self, *args, **kwargs):
# print "has key called"
return True
__delitem__ = __getitem__
========================================
This just logs each access to the dictionary and stores the key under
self.calledAtts
But obviously this won't work if I have #if statements etc. I am hoping
cheetah already has this feature somewhere which is much more robust
but I can't find it.
