NAME

       Template::Namespace::Constants - Compile time constant folding

SYNOPSIS

	   # easy way to define constants
	   use Template;

	   my $tt = Template->new({
	       CONSTANTS => {
		   pi => 3.14,
		   e  => 2.718,
	       },
	   });

	   # nitty-gritty, hands-dirty way
	   use Template::Namespace::Constants;

	   my $tt = Template->new({
	       NAMESPACE => {
		   constants => Template::Namespace::Constants->new({
		       pi => 3.14,
		       e  => 2.718,
		   },
	       },
	   });

DESCRIPTION

       The "Template::Namespace::Constants" module implements a namespace handler which is plugged into the "Template::Directive" compiler module.
       This then performs compile time constant folding of variables in a particular namespace.

METHODS

   new(\%constants)
       The new() constructor method creates and returns a reference to a new Template::Namespace::Constants object.  This creates an internal
       stash to store the constant variable definitions passed as arguments.

	   my $handler = Template::Namespace::Constants->new({
	       pi => 3.14,
	       e  => 2.718,
	   });

   ident(@ident)
       Method called to resolve a variable identifier into a compiled form.  In this case, the method fetches the corresponding constant value
       from its internal stash and returns it.

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
	       All the above constants.
