I have a test file that looks like this:
my $int = new Services::Plugins::FTP::ftp;
$int->AddUser("durr");
The module has this code:
sub AddUser {
my( @username ) = @_;
print "@_\n";
}
But my results looks like: Services::Plugins::FTP::ftp=HASH(0x2490160)durr
I just want 'durr'.
Why am I getting the extra stuff?
You're dealing with object-oriented Perl. If you call a function on an object instance, as in your case with $instance->function(), then the very first parameter is the reference to the instance itself. It is most often called $self.
A commonly used idiom is to write instance methods like this:
sub some_method {
my ($self, @args) = @_;
}
I suggest you read up on Perl's object-oriented system in the perlootut man page (a good tutorial).
The first argument to $foo->bar() is $foo
sub AddUser {
my($self, @username ) = @_;
print "@_\n";
}
You are using Object Oriented approach ($int->AddUser("durr") is a method invocation). When calling a method, the first argument is always the object or the class the method should be applied to.
