I
thought I had read this somewhere, about not being able to use "
cf" as a prefix to a function, but when I defined all those functions in scriptaGulous with that prefix, and it let me, I thought maybe I made the whole thing up.
But then today I was having a look through the
docs for cfscript, and I found this:
Caution: ... You cannot put a user-defined function whose name begins with any of these strings within this tag:
-
cf
-
cf_
-
_cf
-
coldfusion
-
coldfusion_
-
_coldfusion
However, so far it has let me with no problems. What shall be done?

I was thinking... maybe that just means I can't define a function in cfscript that begins with any of those strings.
I ran a test, and sure enough it didn't work. When I tried to call any method on it, it told me the object that held the method wasn't defined.

Doh... maybe not. When I try it outside of a component, like this:
function cfstupendous()
{
return 1;
}
writeoutput(cfstupendous());
I get no problems...

So, the problem I was encountering before was I forgot to "return this;" at the end of my init method.
Oh boy, today is looking like my brain is a bit off!
So, what shall be done?

I also meant to say, looks like Tim (Farrar) was right...

I might be a bit confused - is a cf prefix allowed inside CFCs but not outside of them?

My confusion comes from the fact that indeed, I can use a function prefixed with CF anywhere I try (so scriptaGulous works), but the docs say that it shouldn't work.
The consensus in the few comments at
http://www.codeodor.com/index.cfm/2007/6/7/What-ar...seems to indicate that no one (including at least one person on the CF team - to my knowledge) rates the possibility of these becoming reserved functions.
So, the question now becomes, are they planning to ever fix this "bug," or allow us to use functions with cf as a prefix? (not sure why they'd care much anyway what we named our function as long as it wasn't a reserved word).
As always, insight and advice are much appreciated!

Oh, and Peter - to answer your question, the cf prefix on a function works fine everywhere. The docs do not match the behavior, at least in CFMX 7.
