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 evaluate 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:

       •   Basic markup tags

       The following syntax features of are not supported:

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

       •   Web server interface with tied

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

       •   <: perl statements :>

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

       •   <:= perl expression :>

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

       •   <( 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.
