=head1 NAME

Config::Any - Load configuration from different file formats, transparently

=head1 SYNOPSIS

    use Config::Any;

    my $cfg = Config::Any->load_stems({stems => \@filepath_stems, ... });
    # or
    my $cfg = Config::Any->load_files({files => \@filepaths, ... });

    for (@$cfg) {
        my ($filename, $config) = %$_;
        $class->config($config);
        warn "loaded config from file: $filename";
    }

=head1 DESCRIPTION

L<Config::Any|Config::Any> provides a facility for Perl applications and libraries
to load configuration data from multiple different file formats. It supports XML, YAML,
JSON, Apache-style configuration, Windows INI files, and even Perl code.

The rationale for this module is as follows: Perl programs are deployed on many different
platforms and integrated with many different systems. Systems administrators and end 
users may prefer different configuration formats than the developers. The flexibility
inherent in a multiple format configuration loader allows different users to make 
different choices, without generating extra work for the developers. As a developer
you only need to learn a single interface to be able to use the power of different
configuration formats.

=head1 INTERFACE 

=cut

=head2 load_files( \%args )

    Config::Any->load_files( { files => \@files } );
    Config::Any->load_files( { files => \@files, filter  => \&filter } );
    Config::Any->load_files( { files => \@files, use_ext => 1 } );

C<load_files()> attempts to load configuration from the list of files passed in
the C<files> parameter, if the file exists.

If the C<filter> parameter is set, it is used as a callback to modify the configuration 
data before it is returned. It will be passed a single hash-reference parameter which 
it should modify in-place.

If the C<use_ext> parameter is defined, the loader will attempt to parse the file
extension from each filename and will skip the file unless it matches a standard
extension for the loading plugins. Only plugins whose standard extensions match the
file extension will be used. For efficiency reasons, its use is encouraged, but
be aware that you will lose flexibility -- for example, a file called C<myapp.cfg> 
containing YAML data will not be offered to the YAML plugin, whereas C<myapp.yml>
or C<myapp.yaml> would be.

C<load_files()> also supports a 'force_plugins' parameter, whose value should be an
arrayref of plugin names like C<Config::Any::INI>. Its intended use is to allow the use 
of a non-standard file extension while forcing it to be offered to a particular parser.
It is not compatible with 'use_ext'. 

You can supply a C<driver_args> hashref to pass special options to a particular
parser object. Example:

    Config::Any->load_files( { files => \@files, driver_args => {
        General => { -LowerCaseNames => 1 }
    } )

=cut

sub load_files {
    my ( $class, $args ) = @_;

    unless ( $args && exists $args->{ files } ) {
        warn "No files specified!";
        return;
    }

    return $class->_load( $args );
}

=head2 load_stems( \%args )

    Config::Any->load_stems( { stems => \@stems } );
    Config::Any->load_stems( { stems => \@stems, filter  => \&filter } );
    Config::Any->load_stems( { stems => \@stems, use_ext => 1 } );

C<load_stems()> attempts to load configuration from a list of files which it generates
by combining the filename stems list passed in the C<stems> parameter with the 
potential filename extensions from each loader, which you can check with the
C<extensions()> classmethod described below. Once this list of possible filenames is
built it is treated exactly as in C<load_files()> above, as which it takes the same
parameters. Please read the C<load_files()> documentation before using this method.

    my ( $class, $args ) = @_;

            my @configs
                = eval { $loader->load( $filename, $loader_args{ $loader } ); };

=head2 finder( )

The C<finder()> classmethod returns the

more information.

}

=head2 plugins( )

The C<plugins()> classmethod returns the names of configuration loading plugins as 
found by L<Module::Pluggable::Object|Module::Pluggable::Object>.

=cut

sub plugins {
    my $class = shift;
    return $class->finder->plugins;

=head2 extensions( )

The C<extensions()> classmethod returns the possible file extensions which can be loaded
by C<load_stems()> and C<load_files()>. This may be useful if you set the C<use_ext>
parameter to those methods.

=head1 DIAGNOSTICS

=over

=item C<No files specified!> or C<No stems specified!>

The C<load_files()> and C<load_stems()> methods will issue this warning if
called with an empty list of files/stems to load.

=item C<_load requires a arrayref of file paths>

This fatal error will be thrown by the internal C<_load> method. It should not occur
but is specified here for completeness. If your code dies with this error, please
email a failing test case to the authors below.

=back

=head1 CONFIGURATION AND ENVIRONMENT

Config::Any requires no configuration files or environment variables.
