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.
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
All the above constants.
