routines

ABSTRACT

Typeable Method and Function Signatures

SYNOPSIS

  package main;

  use strict;
  use warnings;

  use routines;

  fun hello($name) {
    "hello, $name"
  }

  hello("world");

DESCRIPTION

This pragma is used to provide typeable method and function signtures to the calling package, as well as before, after, around, augment and override method modifiers.

  package main;

  use strict;
  use warnings;

  use registry;
  use routines;

  fun hello(Str $name) {
    "hello, $name"
  }

  hello("world");

Additionally, when used in concert with the registry pragma, this pragma will check to determine whether a Type::Tiny registry object is associated with the calling package and if so will use it to reify type constraints and resolve type expressions.

  package Example;

  use Moo;

  use registry;
  use routines;

  fun new($class) {
    bless {}, $class
  }

  method hello(Str $name) {
    "hello, $name"
  }

  around hello(Str $name) {
    $self->{name} = $name;

    $self->$orig($name);
  }

  1;

This functionality is based on Function::Parameters and uses Perl's keyword plugn API to provide new keywords. As mentioned previously, this pragma makes the before, after, around, augment, and override method modifiers available to the calling package where that functionality is already present in its generic subroutine callback form.
