SYNOPSIS | [ Index ] [ Modules ] [ Top ]

        use Template::Constants qw( :status :error :all );

DESCRIPTION | [ Index ] [ Modules ] [ Top ]

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 | [ Index ] [ Modules ] [ Top ]

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

      :chomp                      # for PRE_CHOMP and POST_CHOMP
        CHOMP_NONE                # do not remove whitespace
        CHOMP_ALL                 # remove whitespace
        CHOMP_COLLAPSE            # collapse whitespace to a single space

      :all         All the above constants.
