NAME

Coerce::Types::Standard - Coercing

VERSION

Version 0.000008

SYNOPSIS

        package Headache;

        use Coerce::Types::Standard qw/Str HashRef ArrayRef StrToHash StrToArray/;

        attributes(
                [qw/sleep/] => [StrToHash->by(' '), {coe}]
        );

Exports

Coerce::Types::Standard extends Types::Standard it exports Nothing by default. The following outlines the additional types that can be exported using this module.

StrToArray

Accepts a string and coerces it into a ArrayRef, You can specify how to split the string by instantiating with *by*.

        StrToArray->by('--')->coerce('mid--flight--documenter');
        *-*-*-*-*-*-*
        [qw/mid flight documenter/]
        

StrToHash

Accepts a string and coerces it into a HashRef, You can specify how to split the string by instantiating with *by*.

        StrToHash->by(", ")->coerce('I, drink, way, too, much, coffee');
        *-*-*-*-*-*-*
        {
                I => 'drink',
                way => 'too',
                much => 'coffee',
        }

StrSR

Accepts a string and coerces via a search and replace regex generated by the arrayref passed into *by*, optionally the second argument can also be a callback function.

        StrSR->by(['-', ':'])->coerce('beach_bar');
        *-*-*-*-*-*-*
        'beach:bar'

ArrayToHash

Accepts an ArrayRef and coerces it into a HashRef, the default behaviour here is to just dereference the array into a hash.

        ArrayToHash->coerce([qw/north south east west/]);
        *-*-*-*-*-*-*
        {
                north => 'south',
                east => 'west'
        }

You can also instantiate this object via *by* and passing in a *mode*, currently the following are your options.

odd

Only build my hash out of the odd **index** of the array (1, 3, 5, 7 .....)

        ArrayToHash->by('odd')->coerce([qw/zero one two three/]);
        *-*-*-*-*-*-*
        {
                one => 'three',
        }
even

Only build my hash out of the even **index** of the array (0, 2, 4, 6 .....)

        ArrayToHash->by('even')->coerce([qw/zero one two three/]);
        *-*-*-*-*-*-*
        {
                zero => 'two',
        }
reverse

Reverse the default behavior so keys are values and values are keys.

        ArrayToHash->by('reverse')->coerce([qw/north south east west/]);
        *-*-*-*-*-*-*
        {
                south => 'north',
                west => 'east'
        }
flat

Should convert any struct into a one level Hash.

        ArrayToHash->by('flat')->coerce([{ ux => 'ui', analyst => [qw/document support meeting/] }, [qw/sysAdmin backend db deploy/]]); 
        *-*-*-*-*-*-*
        {
                analyst => 'document',
                ux => 'ui',
                support => 'meeting',
                db => 'deploy',
                sysAdmin => 'backend'
        }
merge

Simple single level merge of an array of hash references.

        ArrayToHash->by('merge')->coerce([{ simple => 'merge' }, { simple => 'life' }]);
        *-*-*-*-*-*-*
        {
                simple => 'life'
        }

HashToArray

        HashToArray->coerce({ 
                Malaysia => 'KL', 
                Austrailia => 'Sydney',   
                Indonesia => 'Bali',
        });
        *-*-*-*-*-*-*
