=head1 Trog::Config

A thin wrapper around Config::Simple which reads the configuration from the appropriate place.

=head2 Trog::Config::get() = Config::Tiny

Returns a configuration object that will be used by server.psgi, the data model and Routing modules.
The object will be cached in memory, so that re-run of get() will return the object fetched earlier.
Pass in a truthy argument to force refetch.

=cut

our $home_cfg = "config/main.cfg";

my $cf;

sub get {
    my ($refetch) = @_;
    undef $cf if $refetch;
    return $cf if $cf;
    $cf = Config::Tiny->read($home_cfg) if -f $home_cfg;
    return $cf if $cf;
    $cf = Config::Tiny->read('config/default.cfg');
    return $cf;
}

=head2 Trog::Config::theme_dir()

Returns string corresponding to the path of the theme in use per config.
The string will be cached in memory, so that re-run of get() will return the object fetched earlier.
Pass in a truthy argument to force refetch of both theme dir and config object.

=cut

my $theme_dir = '';
sub theme_dir {
    my ($refetch) = @_;
    $theme_dir = '' if $refetch;
    return $theme_dir if $theme_dir;
    get($refetch) if !$cf || $refetch;
    $theme_dir = "themes/$cf->{'general'}{'theme'}" if $cf->{'general'}{'theme'} && -d "www/themes/$cf->{'general'}{'theme'}";
    return $theme_dir;
}
