Template::Constants - Defines constants for the Template Toolkit
use Template::Constants qw( :template :status :error :ops :cache :debug :all );
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; use Template::Constants; my $template = Template->new({ DEBUG => Template::Constants::DEBUG_ALL });
Constants may be imported into the caller's namespace by naming them as options to the use Template::Constants statement:
use Template::Constants
use Template::Constants qw( DEBUG_ALL );
Alternatively, one of the following tagset identifiers may be specified (prefixed by ':') to import sets of constants; reset, notify, expand, debug.
use Template; use Template::Constants qw( :debug ); my $template = Template->new({ DEBUG => DEBUG_ALL });
The Template module uses the Template::Constants module and delegates any import specifications to it. Thus, it is sufficient to use Template without requiring a further use Template::Constants.
use Template
use Template qw( :error :debug ); my $template = Template->new({ DEBUG => DEBUG_ALL });
See Exporter for more information on exporting variables.
The following tag sets and associated constants are defined:
:template General purpose Template control parameters. TEMPLATE_OUTPUT # indicates output "stream" TEMPLATE_ERROR # indicates error "stream" :status Status codes, returned by toolkit and user code 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_ERROR # general error condition (not ok) :error Error (exception) types thrown by toolkit ERROR_FILE # file missing or parse error ERROR_UNDEF # undefined variables :ops Fundamental 'opcodes' of context runtime. (see Context::_runop() for details) :all All the above constants.
