NAME

       Text::MicroMason::PostProcess - Apply Filters to All Template Output

SYNOPSIS

       Instead of using this class directly, pass its name to be mixed in:

	   use Text::MicroMason;
	   my $mason = Text::MicroMason->new( -PostProcess );

       Use the standard compile and execute methods to parse and evalute templates:

	 print $mason->compile( text=>$template )->( @%args );
	 print $mason->execute( text=>$template, @args );

       You can define output filters at creation or subsequently:

	   $mason = Text::MicroMason->new( -PostProcess, post_process => $func );

	   $mason->post_processors( $func );

	   $mason->compile( text => $template, post_process => $func );

	   $mason->execute( text => $template, { post_process => $func }, @args );

DESCRIPTION

       This mixin class adds filtering of all template output to any MicroMason class.

       Filter functions can accept the string to be output and return a filtered version:

	 $mason->post_process( sub {
	   my $foo = shift;
	   $foo =~ s/a-Z/A-Z/;
	   return $foo;
	 } );

       If a filter function has an empty prototype, it's assumed to work on $_:

	 $mason->post_process( sub () {
	   s/a-Z/A-Z/
	 } );

   Public Methods
       post_processors()
	   Gets and sets the functions to be used for output filtering.

	   Called with no arguments, returns the list of filter functions:

	     my @functions = $mason->post_processors();

	   Called with one array-ref argument, sets the list of filter functions:

	     $mason->post_processors( @functions );

	   Called with one or more function-ref arguments, appends to the list:

	     $mason->post_processors( $filter1, $filter2 );

   Supported Attributes
       post_process
	   Stores a reference to a function or an array of functions to be used:

	     $mason->{post_process} = $function;
	     $mason->{post_process} = [ $function1, $function2 ];

	   You can set this attribute when you create your mason object, or in calls to the compile and execute methods.

   Private Methods
       post_process()
	     $mason->post_process( $output ) : $filtered_output

	   Applies the post-processing filter.
