=head1 NAME

Config::Any::INI - Load INI config files

=head1 DESCRIPTION

Loads INI files. Example:

name=TestApp

[Controller::Foo]
    foo=bar

[Model::Baz]
    qux=xyzzy

=head1 METHODS

=head2 extensions( )

return an array of valid extensions (C<ini>).

=cut

sub extensions {
    return qw( ini );
}

=head2 load( $file )

Attempts to load C<$file> as an INI file.

=cut

sub load {
    my $class = shift;
    my $file  = shift;

require Config::Tiny;
    my $config = Config::Tiny->read( $file );

die $Config::Tiny::errstr if not defined $config;

my $out = delete $config->{ _ } || {};

for my $k ( keys %$config ) {
        my @keys = split /\s+/, $k;
        my $ref = $config->{ $k };

if ( $MAP_SECTION_SPACE_TO_NESTED_KEY && @keys > 1 ) {
            my ( $a, $b ) = @keys[ 0, 1 ];
            $out->{ $a }->{ $b } = $ref;
        }
        else {
            $out->{ $k } = { %{ $out->{ $k } || {} }, %$ref };
        }
    }

return $out;
}

=head2 requires_all_of( )

Specifies that this module requires L<Config::Tiny> in order to work.

=cut

sub requires_all_of { 'Config::Tiny' }

=head1 PACKAGE VARIABLES

=over 4

=item $MAP_SECTION_SPACE_TO_NESTED_KEY (boolean)

This variable controls whether spaces in INI section headings will be expanded into nested hash keys.
e.g. it controls whether [Full Power] maps to $config->{'Full Power'} or $config->{'Full'}->{'Power'}

By default it is set to 1 (i.e. true).

Set it to 0 to preserve literal spaces in section headings:

use Config::Any;
    use Config::Any::INI;
    $Config::Any::INI::MAP_SECTION_SPACE_TO_NESTED_KEY = 0;
