file::find::rule::extending
File::Find::Rule::Extending(3) User Contributed Perl Documentation File::Find::Rule::Extending(3)
NAME
File::Find::Rule::Extending - the mini-guide to extending File::Find::Rule
SYNOPSIS
package File::Find::Rule::Random;
use strict;
# take useful things from File::Find::Rule
use base 'File::Find::Rule';
# and force our crack into the main namespace
sub File::Find::Rule::random () {
my $self = shift()->_force_object;
$self->exec( sub { rand > 0.5 } );
}
1;
DESCRIPTION
File::Find::Rule went down so well with the buying public that everyone wanted to add extra features. With the 0.07 release this became a
possibility, using the following conventions.
Declare your package
package File::Find::Rule::Random;
use strict;
Inherit methods from File::Find::Rule
# take useful things from File::Find::Rule
use base 'File::Find::Rule';
Force your madness into the main package
# and force our crack into the main namespace
sub File::Find::Rule::random () {
my $self = shift()->_force_object;
$self->exec( sub { rand > 0.5 } );
}
Yes, we're being very cavalier here and defining things into the main File::Find::Rule namespace. This is due to lack of imaginiation on
my part - I simply can't find a way for the functional and oo interface to work without doing this or some kind of inheritance, and
inheritance stops you using two File::Find::Rule::Foo modules together.
For this reason try and pick distinct names for your extensions. If this becomes a problem then I may institute a semi-official registry
of taken names.
Taking no arguments.
Note the null prototype on random. This is a cheat for the procedural interface to know that your sub takes no arguments, and so allows
this to happen:
find( random => in => '.' );
If you hadn't declared "random" with a null prototype it would have consumed "in" as a parameter to it, then got all confused as it doesn't
know about a '.' rule.
