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.

NAME

       Text::MicroMason::PLP - Alternate Syntax like PLP Templates

SYNOPSIS

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

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

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

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

       The PLP syntax provides another way to mix Perl into a text template:

	   <: my $name = $ARGS{name};
	     if ( $name eq 'Dave' ) {  :>
	     I'm sorry <:= $name :>, I'm afraid I can't do that right now.
	   <: } else {
	       my $hour = (localtime)[2];
	       my $daypart = ( $hour > 11 ) ? 'afternoon' : 'morning';
	     :>
	     Good <:= $daypart :>, <:= $name :>!
	   <: } :>

DESCRIPTION

       This subclass replaces MicroMason's normal lexer with one that supports a syntax similar to that provided by the PLP module.

   Compatibility with PLP
       PLP is a web-oriented system with many fatures, of which only the templating functionality is emulated.

       This is not a drop-in replacement for PLP, as the implementation is quite different, but it should be able to process some existing
       templates without major changes.

       The following features of EmbPerl syntax are supported:

       o   Basic markup tags

       The following syntax features of are not supported:

       o   Emulation of functions defined in PLP::Functions is incomplete.

       o   Web server interface with tied

   Template Syntax
       The following elements are recognized by the PLP lexer:

       o   <: perl statements :>

	   Arbitrary Perl code to be executed at this point in the template.

       o   <:= perl expression :>

	   A Perl expression to be evaluated and included in the output.

       o   <( file, arguments )>

	   Includes an external template file.

   Private Methods
       lex_token
	     ( $type, $value ) = $mason->lex_token();

	   Lexer for <: ... :> and <( ... )> tags.

	   Attempts to parse a token from the template text stored in the global $_ and returns a token type and value. Returns an empty list if
	   unable to parse further due to an error.

       assemble
	   Performs compile-time file includes for any include tokens found by lex_token.

SEE ALSO

       The interface being emulated is described in PLP.
