Using functions from their own package

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi there. What's the best way to refer to a function inside a package from within the package functions itself?

I haven't worked with modules much until now, so I've been writing:

package myPackage;
sub function1{
  #do stuff
  myPackage->function2($thing)
  #do stuff
} 
sub function2{
  #do stuff
}
[download]

Does Perl provide a better way to do it?

Yes, exactly. To elaborate on Anonymous Monk’s answer: `12:41 >perl -Mstrict -wE "package myPackage; sub function1 { myPackage +::function2('Hi!'); } sub function2 { say qq[@_]; } function1();" Hi! 12:41 >perl -Mstrict -wE "package myPackage; sub function1 { function2 +('Hi!'); } sub function2 { say qq[@_]; } function1();" Hi! 12:41 >perl -Mstrict -wE "package myPackage; sub function1 { myPackage +->function2('Hi!'); } sub function2 { say qq[@_]; } function1();" myPackage Hi! 12:41 >` [download] Within the package, prepending `myPackage::` to a function name is merely redundant. But prepending `myPackage->` changes the behaviour: it passes the package name to the function as the first argument. Hope that helps, Athanasius <°(((>< contra mundum	[reply] [d/l]

You should call functions by using `foo() or myPackage::foo()` You should reserve use of -> for methods only	[reply] [d/l]
