=head1 NAME

Locale::Maketext::Utils::Mock - mock locale object

=head1 VERSION

This document describes Locale::Maketext::Utils::Mock version 0.1

=head1 SYNOPSIS

    use Locale::Maketext::Utils::Mock;
    my $lh = Locale::Maketext::Utils::Mock->get_handle();

=head1 DESCRIPTION

Often we need to create a class so we can do a Locale::Maketext[::Utils] testing but Locale::Maketext is not designed for direct use. Instead you need to create a class with a lexicon and at least the 'en' subclass of that.

This module does all the work for you and behaves like a typical L<Locale::Maketext::Utils> object.

You can also add additional locales at will.

=head1 INTERFACE

=head2 get_handle()

Requires the L<Locale::Maketext::Utils::Mock> based locale handle.

=head2 init_mock_locales()

If you want more than 'en' you can initialize them using init_mock_locales();

It takes a list of locales tags, passes them through L<Locales::normalize_tag()|Locales/Utility functions> and creates the subclass for each one that can be used to create a L<Locales> object or that is an “i_” tag (e.g. i_yoda).

    use Locale::Maketext::Utils::Mock ();
    Locale::Maketext::Utils::Mock->init_mock_locales('fr', 'it', 'en_gb');
    my $it = Locale::Maketext::Utils::Mock->get_handle('it'); # Locale::Maketext::Utils::Mock::it object.
    my $ja = Locale::Maketext::Utils::Mock->get_handle('js'); # Locale::Maketext::Utils::Mock::en object since there is no 'ja' subclass.

It can be called as a function, a class method, or object method.

It returns the number of subclasses successfully created.

=head2 create_method()

Takes a hashref whose keys are the methods to make for mocked objects.

The values are either a coderef for the method or undef. Undef will result in a coderef that returns “I am $key()”.

    use Locale::Maketext::Utils::Mock ();
    Locale::Maketext::Utils::Mock->create_method({ method_x => undef, method_y => sub { return "YABBA DABBA $_[1]" } });
    my $lh = Locale::Maketext::Utils::Mock->get_handle();
    print $lh->maketext("Blah [method_x] blah [method_y,_1] blah.", 42); $ Blah I am method_x() blah YABBA DABBA 42 blah.

=head1 DIAGNOSTICS

init_mock_locales() carp()s if there was a problem createing the subclass.

=head1 CONFIGURATION AND ENVIRONMENT

Locale::Maketext::Utils::Mock requires no configuration files or environment variables.

=head1 DEPENDENCIES

L<Locale::Maketext::Utils>

=head1 INCOMPATIBILITIES

None reported.

=head1 BUGS AND LIMITATIONS

No bugs have been reported.

Please report any bugs or feature requests to
C<bug-locale-maketext-utils-mock@rt.cpan.org>, or through the web interface at
L<http://rt.cpan.org>.

=head1 TODO

Depending on need/demand:

1. Add a way to define lexicon for specifical locales.

2. ? ability to create object in it's own class (so subclass modification are separate) ?
