SYNOPSIS
use App::CELL::Config qw( $meta $core $site );
# get a parameter value (returns value or undef)
my $value;
$value = $meta->MY_PARAM;
$value = $core->MY_PARAM;
$value = $site->MY_PARAM;
# set a meta parameter
$meta->set( 'MY_PARAM', 42 );
# set an as-yet undefined core/site parameter
$core->set( 'MY_PARAM', 42 );
$site->set( 'MY_PARAM', 42 );
DESCRIPTION
The purpose of the App::CELL::Config module is to maintain and provide access to three package variables, $meta, $core, and $site, which are actually singleton objects, containing configuration parameters loaded by App::CELL::Load from files in the distro sharedir and the site configuration directory, if any.For details, read App::CELL::Guilde.
EXPORTS
This module exports three scalars: the 'singleton' objects $meta, $core, and $site.SUBROUTINES
AUTOLOAD
The "AUTOLOAD" routine handles calls that look like this:$meta->MY_PARAM
$core->MY_PARAM
$site->MY_PARAM
DESTROY
For some reason, Perl 5.012 seems to want a DESTROY methodexists
Determine parameter existence.get
Wrapper for get_paramget_param
Get value of config param provided in the argument.get_param_metadata
Routine to provide access not only to the value, but also to the metadata (file and line number where parameter was defined) associated with a given parameter.Takes: parameter name. Returns: reference to the hash associated with the given parameter, or undef if no parameter found.
set
Use this function to set new params (meta/core/site) or change existing ones (meta only). Takes two arguments: parameter name and new value. Returns a status object.
