Template::Constants(3pUser Contributed Perl DocumentatTemplate::Constants(3pm)
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;
Consult the documentation for the "Exporter" module for more
information on exporting variables.
EXPORTABLE TAG SETS

:status
STATUS_OK # no problem, continue
STATUS_RETURN # ended current block then continue (ok)
