Re: How to check if a function exists within a package?

For functions, defined.

if ( defined( &perlmonk::funnyfunction ) )

For methods, can. Checks inheritance.

if ( perlmonk->can('funnyfunction') )
[download]

if ( $obj->can('funnyfunction') )
[download]

`if ( defined( &perlmonk::funnyfunction ) )` Why wouldn't that call the function passing in @_ and check defined on the result? I mean, I see that it doesn't do that, but why? You have to put the ()'s on the end of it to get what I'd expect. -Paul	[reply] [d/l]

It's just another special parsing rule. `exists` and `goto` are exactly the same, but they are hardly the only three functions that have special parsing rules. `map`'s curlies don't create a hash. `print`'s file handle isn't a function name. And the list goes on.	[reply] [d/l] [select]

Great answer. Since I had methods it was the right answer to use can. Thanks everyone!	[reply]
