NAME ^

Method::Signatures::Simple - Basic method declarations with signatures, without source filters

VERSION ^

version 1.07

SYNOPSIS ^

    # -- a basic class -- #
    package User;
    use Method::Signatures::Simple;

    method new ($class: $name, $email) {
        my $user = {
            id    => new_id(42),
            name  => $name,
            email => $email,
        };
        bless $user, $class;
    }

    func new_id ($seed) {
        state $id = $seed;
        $id++;
    }

    method name  { $self->{name};  }
    method email { $self->{email}; }
    1;


    # -- other features -- #
    # attributes
    method foo : lvalue { $self->{foo} }

    # change invocant name
    use Method::Signatures::Simple invocant => '$this';
    method foo ($bar) { $this->bar($bar) }
    method bar ($class: $bar) { $class->baz($bar) }

    # use a different function keyword
    use Method::Signatures::Simple function_keyword => 'fun';
    fun triple ($num) { 3 * $num }

    # use a different method keyword
    use Method::Signatures::Simple method_keyword => 'action';
    action foo { $self->bar }

RATIONALE ^

This module provides basic method and func keywords with simple signatures. It's intentionally simple, and is supposed to be a stepping stone for its bigger brothers MooseX::Method::Signatures and Method::Signatures. It only has a small benefit over regular subs, so if you want more features, look at those modules. But if you're looking for a small amount of syntactic sugar, this might just be enough.

FEATURES ^

ADVANCED CONFIGURATION ^

Since this module subclasses Devel::Declare::MethodInstaller::Simple, you can change the keywords and the default invocant with import arguments. These changes affect the current scope.
