I have a cheetah template something like this:
x is: $x
y is: $y
z is: $z
[Actually more complicated]
If for example $y is not defined I get an exception and the parsing
of the template stops. Is there any way to substitute $y with an emty
string and making cheeta going on with parsing?
Thnx

Actually I wanted to keep things simple for who writes the template,
so I am using this workaround: I define a class
class ClassMapper:
def __init__(self,dict={}):
self.__dict=dict
def getValue(self,str):
try:
return self.__dict[str]
except KeyError:
return ""
x=ClassMapper(dict)
Template(definition, searchList=[{"info":x.getValue}])
so the user should do
$info("name")
Maybe I could define a class that implements a dictionary and doesn''t
raise an exception for a key not present... but it seems to
complicated.
