Template::Constants - Defines constants for the Template Toolkit

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 the Exporter manpage 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_ALL                 # remove whitespace
    CHOMP_COLLAPSE            # collapse whitespace to a single space

  :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         All the above constants.
