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.
