πŸ’– NAME πŸ’–

File::Find::Object::Rule::Extending β€” bestie, this is literally the mini-guide to extending File::Find::Object::Rule. That's it, that's the whole job. πŸŽ€


✨ VERSION ✨

version 0.0313


🌸 SYNOPSIS 🌸

package File::Find::Object::Rule::Random;

use strict;
use warnings;

# take useful things from File::Find::Object::Rule
use base 'File::Find::Object::Rule';

# and force our crack into the main namespace
sub File::Find::Object::Rule::random () {
    my $self = shift()->_force_object;
    $self->exec( sub { rand > 0.5 } );
}

1;

πŸ¦‹ DESCRIPTION πŸ¦‹

So File::Find::Object::Rule inherits the whole extensibility thing from File::Find::Rule, okay? Which means you can extend it β€” and here are the conventions you're gonna follow to do it. No cap. πŸ’…

πŸŽ€ Declare your package

package File::Find::Object::Rule::Random;

use strict;
use warnings;

🧚 Inherit methods from File::Find::Object::Rule

# take useful things from File::Find::Object::Rule
use base 'File::Find::Object::Rule';

Force your madness into the main package:

# and force our crack into the main namespace
sub File::Find::Object::Rule::random () {
    my $self = shift()->_force_object;
    $self->exec( sub { rand > 0.5 } );
}

Yeah okay, we're being very cavalier here β€” we're literally defining stuff straight into the main File::Find::Object::Rule namespace. 😭 And why? Because the author ran out of imagination, fr fr. They straight up could not find a way to make the functional interface and the oo interface both work without doing this, or without some kind of inheritance β€” and inheritance stops you from using two File::Find::Object::Rule::Foo modules together. Tragic.

So for that reason: try and pick distinct names for your extensions. 🫢 If it ever becomes a whole problem, there might be a semi-official registry of taken names. Iconic, honestly.

🌈 Taking no arguments.

Not me pointing at the null prototype on random β€” πŸ‘€ notice it. It's a cheat, a little hack, so the procedural interface knows 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 eaten in as a parameter to it, and then gotten all confused because it doesn't know about a . rule. πŸ’€ So like. Declare it.


πŸ”₯ NOTES ABOUT THE CALLBACK πŸ”₯

The callback can access the File::Find::Object::Result using $self->finder->item_obj(). That's the plug, that's how you get in. ⭐
