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
       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)
               STATUS_DONE           # iterator is all done (ok)
               STATUS_DECLINED       # provider declined to service request (ok)
               STATUS_ERROR          # general error condition (not ok)

           :error
               ERROR_RETURN          # return a status code (e.g. 'stop')
               ERROR_FILE            # file error: I/O, parse, recursion
               ERROR_UNDEF           # undefined variable value used
               ERROR_PERL            # error in [% PERL %] block
               ERROR_FILTER          # filter error
               ERROR_PLUGIN          # plugin error

           :chomp                  # for PRE_CHOMP and POST_CHOMP
               CHOMP_NONE            # do not remove whitespace
               CHOMP_ONE             # remove whitespace to newline
               CHOMP_ALL             # old name for CHOMP_ONE (deprecated)
               CHOMP_COLLAPSE        # collapse whitespace to a single space
               CHOMP_GREEDY          # remove all whitespace including newlines

           :debug
               DEBUG_OFF             # do nothing
               DEBUG_ON              # basic debugging flag
               DEBUG_UNDEF           # throw undef on undefined variables
               DEBUG_VARS            # general variable debugging
               DEBUG_DIRS            # directive debugging
               DEBUG_STASH           # general stash debugging
               DEBUG_CONTEXT         # context debugging
               DEBUG_PARSER          # parser debugging
               DEBUG_PROVIDER        # provider debugging
               DEBUG_PLUGINS         # plugins debugging
               DEBUG_FILTERS         # filters debugging
               DEBUG_SERVICE         # context debugging
               DEBUG_ALL             # everything
               DEBUG_CALLER          # add caller file/line info
               DEBUG_FLAGS           # bitmap used internally

               All the above constants.
