NAME
Template::Constants - Defines constants for the Template Toolkit
SYNOPSIS
use Template::Constants qw( :status :error :all );DESCRIPTION
The Template::Constants modules defines, and optionally exports into the caller's namespace, a number of constants used by the Template package.
Constants may be used by specifying the Template::Constants package explicitly:
use Template::Constants;
print Template::Constants::STATUS_DECLINED;Constants may be imported into the caller's namespace by naming them as options to the use Template::Constants statement:
use Template::Constants qw( STATUS_DECLINED );
print STATUS_DECLINED;Alternatively, one of the following tagset identifiers may be specified to import sets of constants; :status, :error, :all.
use Template::Constants qw( :status );
print STATUS_DECLINED;See Exporter for more information on exporting variables.
EXPORTABLE TAG SETS
The following tag sets and associated constants are defined:
:status
STATUS_OK # no problem, continue
STATUS_RETURN # ended current block then continue (ok)
STATUS_STOP # controlled stop (ok)
