NAME

Exporter::Declare::Magic - Enhance Exporter::Declare with some fancy magic.

DESCRIPTION

SYNOPSIS

    package Some::Exporter;
    use Exporter::Declare::Magic;

    ... #Same as the basic Exporter::Declare synopsis

    #Quoting is not necessary unless you have space or special characters
    export another_sub;
    export parsed_sub parser;

    # no 'sub' keyword, not a typo
    export anonymous_export {
        ...
    }
    #No semicolon, not a typo

    export parsed_anon parser {
        ...
    }

    # Same as export
    default_export name { ... }

    # No quoting required
    export $VAR;
    export %VAR;

    my $iterator = 'a';
    gen_export unique_class_id {
        my $current = $iterator++;
        return sub { $current };
    }

    gen_default_export '$my_letter' {
        my $letter = $iterator++;
        return \$letter;
    }

    parser myparser {
        ... See Devel::Declare
    }

    parsed_exports parser => qw/ parsed_sub_a parsed_sub_b /;
    parsed_default_exports parser_b => qw/ parsed_sub_c /;

API

These all work fine in function or method form, however the syntax sugar will only work in function form.

parsed_exports( $parser, @exports )

Add exports that should use a 'Devel::Declare' based parser. The parser should be the name of a registered Devel::Declare::Interface parser, or the name of a parser sub created using the parser() function.

parsed_default_exports( $parser, @exports )

Same as parsed_exports(), except exports are added to the -default tag.

parser name { ... }
parser name => \&code

Define a parser. You need to be familiar with Devel::Declare to make use of this.

export( $name )
export( $name, $ref )
export( $name, $parser )
export( $name, $parser, $ref )
export name { ... }
export name parser { ... }

export is a keyword that lets you export any 1 item at a time. The item can be exported by name, name+ref, or name+parser+ref. You can also use it without parentheses or quotes followed by a codeblock.

default_export( $name )
default_export( $name, $ref )
default_export( $name, $parser )
default_export( $name, $parser, $ref )
default_export name { ... }
default_export name parser { ... }
gen_export( $name )
gen_export( $name, $ref )
gen_export( $name, $parser )
gen_export( $name, $parser, $ref )
gen_export name { ... }
gen_export name parser { ... }
gen_default_export( $name )
gen_default_export( $name, $ref )
gen_default_export( $name, $parser )
gen_default_export( $name, $parser, $ref )
gen_default_export name { ... }
gen_default_export name parser { ... }

These all act just like export(), except that they add subrefs as generators, and/or add exports to the -default tag.
