App::CELL::Config -- load, store, and dispense meta parameters, core parameters, and site parameters
Version 0.183
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 );
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.
$meta
$core
$site
For details, read App::CELL::Guilde.
This module exports three scalars: the 'singleton' objects $meta, $core, and $site.
The AUTOLOAD routine handles calls that look like this: $meta->MY_PARAM $core->MY_PARAM $site->MY_PARAM
AUTOLOAD
For some reason, Perl 5.012 seems to want a DESTROY method
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.
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.
