My Secret Life as a Spaghetti Coder

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;


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

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.
