NAME

       Template::Alloy::Compile - Compile role - allows for compiling the AST to perl code

DESCRIPTION

       The Template::Alloy::Compile role allows for taking the AST returned by the Parse role, and translating it into a perl code document.  This
       is in contrast Template::Alloy::Play which executes the AST directly.

TODO

       o   Translate compile_RAWPERL to actually output rather than calling play_RAWPERL.

ROLE METHODS

       "compile_tree"
	   Takes an AST returned by parse_tree and translates it into perl code using functions stored in the $DIRECTIVES hashref.

	   A template that looked like the following:

	       Foo
	       [% GET foo %]
	       [% GET bar %]
	       Bar

	   would parse to the following perl code:

	       # Generated by Template::Alloy::Compile v1.001 on Thu Jun  7 12:58:33 2007
	       # From file /home/paul/bar.tt

	       my $blocks = {};
	       my $meta   = {};
	       my $code   = sub {
		   my ($self, $out_ref, $var) = @_;

		   $$out_ref .= 'Foo';

		   # "GET" Line 2 char 2 (chars 6 to 15)
		   $var = $self->play_expr(['foo', 0]);
		   $$out_ref .= defined($var) ? $var : $self->undefined_get(['foo', 0]);

		   # "GET" Line 3 char 2 (chars 22 to 31)
		   $var = $self->play_expr(['bar', 0]);
		   $$out_ref .= defined($var) ? $var : $self->undefined_get(['bar', 0]);

		   $$out_ref .= 'Bar';

		   return 1;
	       };

	       {
		   blocks => $blocks,
		   meta   => $meta,
		   code   => $code,
	       };

	   As you can see the output is quite a bit more complex than the AST, but under mod_perl conditions, the perl will run faster than
	   playing the AST each time.

       "compile_expr"
	   Takes an AST variable or expression and returns perl code that can lookup the variable.

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.
