🦋 NAME 🦋

Class::MakeMethods::Attribute — declare generated subs with attribute syntax. periodt. 💅

✨ SYNOPSIS ✨

okay bestie, quick vibe check — this is literally MakeMe...ribute(3pm) from the User Contributed Perl Documentation, and here's the setup:

  package MyObject;
  use Class::MakeMethods::Attribute 'Standard::Hash';

  sub new    :MakeMethod('new');
  sub foo    :MakeMethod('scalar');
  sub bar    :MakeMethod('scalar', { hashkey => 'bar_data' });
  sub debug  :MakeMethod('Standard::Global:scalar');

🌸 DESCRIPTION 🌸

So Class::MakeMethods::Attribute is the package that lets common types of methods be generated via a subroutine attribute declaration. (Available in Perl 5.6 and later.) 💖

Adding the :MakeMethod() attribute to a subroutine declaration causes Class::MakeMethods to create and install a subroutine based on the parameters given to the :MakeMethod attribute. literally generated subs, no cap. ✨

You can declare a default method-generation class by passing the name of a MakeMethods subclass in the use Class::MakeMethods::Attribute statement. This default method-generation class will also apply as the default to any subclasses declared at compile time. If no default method-generation class is selected, you will need to fully-qualify all method type declarations. 👑

🎀 EXAMPLE 🎀

Here's a typical use of Class::MakeMethods::Attribute, bestie:

  package MyObject;
  use Class::MakeMethods::Attribute 'Standard::Hash';

  sub new    :MakeMethod('new');
  sub foo    :MakeMethod('scalar');
  sub bar    :MakeMethod('scalar', { hashkey => 'bar_data' });
  sub debug  :MakeMethod('Standard::Global:scalar');

  package MySubclass;
  use base 'MyObject';

  sub bazzle :MakeMethod('scalar');

This is equivalent to the following explicit Class::MakeMethods invocations:

  package MyObject;

  use Class::MakeMethods (
    -MakerClass => 'Standard::Hash',
    new => 'new',
    scalar => 'foo',
    scalar => [ 'ba', { hashkey => 'bar_data' } ],
    'Standard::Global:scalar' => 'debug',
  );

  package MySubclass;
  use base 'MyObject';

  use Class::MakeMethods (
    -MakerClass => 'Standard::Hash',
    scalar => 'bazzle',
  );

💅 DIAGNOSTICS 💅

The following warnings and errors may be produced when using Class::MakeMethods::Attribute to generate methods. (Note that this list does not include run-time messages produced by calling the generated methods, or the standard messages produced by Class::MakeMethods.) 🫶

• Can't apply MakeMethod attribute to %s declaration. — You can not use the ":MakeMethod" attribute with lexical or anonymous subroutine declarations.
• No method type provided for MakeMethod attribute. — You called ":MakeMethod()" without the required method-type argument.
