NAME ^

MooseX::Types::Moose::MutualCoercion - Mutual coercions for common type constraints of Moose

VERSION ^

This document describes MooseX::Types::Moose::MutualCoercion version 0.03.

SYNOPSIS ^

    {
        package Foo;
        use Moose;
        use MooseX::Types::Moose::MutualCoercion
            qw(StrToArrayRef ArrayRefToHashKeys);
        has 'thingies' =>
            (is => 'rw', isa => StrToArrayRef, coerce => 1);
        has 'lookup_table' =>
            (is => 'rw', isa => ArrayRefToHashKeys, coerce => 1);
        1;
    }

    my $foo = Foo->new( thingies => 'bar' );
    print $foo->thingies->[0];                              # 'bar'

    $foo->lookup_table( [qw(baz qux)] );
    print 'eureka!'                                         # 'eureka!'
        if grep {
            exists $foo->lookup_table->{$_};
        } qw(foo bar baz);

DESCRIPTION ^

This module packages several Moose::Util::TypeConstraints with coercions, designed to mutually coerce with the built-in and common types known to Moose.

CONSTRAINTS AND COERCIONS ^

NOTE: These constraints are not exported by default but you can request them in an import list like this:

    use MooseX::Types::Moose::MutualCoercion qw(NumToInt ScalarRefToStr);

To Int

NumToInt

A subtype of Int. If you turned coerce on, Num will become integer. For example, 3.14 will be converted into 3.

To Str

ScalarRefToStr

A subtype of Str. If you turned coerce on, ScalarRef[Str] will become dereferenced string. For example, \do{'foo'} will be converted into foo.

ArrayRefToLines

A subtype of Str. If you turned coerce on, all elements of ArrayRef[Str] will be joined by $/. For example, [qw(foo bar baz)] will be converted into foo\nbar\nbaz\n.

NOTE: Also adds $/ to the last element.

To ClassName

StrToClassName

CAVEAT: This type constraint and coercion is DEPRECATED. Please use MooseX::Types::LoadableClass's LodableClass instead of it. In addition, MooseX::Types::LoadableClass also has LodableRole.

A subtype of ClassName. If you turned coerce on, NonEmptyStr, provided by MooseX::Types::Common::String, will be treated as a class name. When it is not already loaded, it will be loaded by Class::MOP::load_class().

To ScalarRef

StrToScalarRef

A subtype of ScalarRef[Str]. If you turned coerce on, Str will be referenced. For example, foo will be converted into \do{'foo'}.

To ArrayRef

StrToArrayRef

A subtype of ArrayRef. If you turned coerce on, Str will be assigned for the first element of an array reference. For example, foo will be converted into [qw(foo)].

LinesToArrayRef

A subtype of ArrayRef. If you turned coerce on, Str will be split by $/ and will be assigned for each element of an array reference. For example, foo\nbar\nbaz\n will be converted into ["foo\n", "bar\n", "baz\n"].

NOTE: $/ was not removed.

HashRefToArrayRef

A subtype of ArrayRef. If you turned coerce on, HashRef will be flattened as an array reference. For example, {foo => 0, bar => 1} will be converted into [qw(bar 1 foo 0)].

NOTE: Order of keys/values is the same as lexically sorted keys.

HashKeysToArrayRef

A subtype of ArrayRef. If you turned coerce on, list of lexically sorted keys of HashRef will become an array reference. For example, {foo => 0, bar => 1} will be converted into [qw(bar foo)].

HashValuesToArrayRef

A subtype of ArrayRef. If you turned coerce on, list of values of HashRef will become an array reference. For example, {foo => 0, bar => 1} will be converted into [qw(1 0)].

NOTE: Order of values is the same as lexically sorted keys.

OddArrayRef

A subtype of ArrayRef, that must have odd elements. If you turned coerce on, ArrayRef, that has even elements, will be pushed undef as the last element. For example, [qw(foo bar)] will be converted into [qw(foo bar), undef].

EvenArrayRef

A subtype of ArrayRef, that must have even elements. If you turned coerce on, ArrayRef, that has odd elements, will be pushed undef as the last element. For example, [qw(foo)] will be converted into [qw(foo), undef].

To HashRef

ArrayRefToHashRef

A subtype of HashRef. If you turned coerce on, all elements of EvenArrayRef will be substituted for a hash reference. For example, [qw(foo 0 bar 1)] will be converted into {foo => 0, bar => 1}.

ArrayRefToHashKeys

A subtype of HashRef. If you turned coerce on, all elements of ArrayRef will be substituted for keys of a hash reference. For example, [qw(foo bar baz)] will be converted into {foo => undef, bar => undef, baz => undef}.

To RegexpRef

ArrayRefToRegexpRef

A subtype of RegexpRef. If you turned coerce on, all elements of ArrayRef will be joined with | (the meta character for alternation) and will become a regular expression reference. For example, [qw(foo bar baz)] will be converted into qr{foo|bar|baz}.

NOTE: If Regexp::Assemble can be loaded dynamically, namely at runtime, a regular expression reference will be built with this module. For example, [qw(foo bar baz)] will be converted into qr{(?:ba[rz]|foo)}.
