NAME

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

SYNOPSIS

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

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

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

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

       Embperl syntax provides several ways 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 +], [+ $name +]!
	   [$ endif $]

DESCRIPTION

       This subclass replaces MicroMason's normal lexer with one that supports a syntax similar to Embperl.

   Compatibility with Embperl
       Embperl is a full-featured application server toolkit with many fatures, of which only the templating functionality is emulated.

       This is not a drop-in replacement for Embperl, 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   Square-bracket markup tags

       The following syntax features of are not supported:

       o   Dynamic HTML tags

   Template Syntax
       The following elements are recognized by the Embperl 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   [! perl statements !]

	   Arbitrary Perl code to be executed once when the template is compiled.

       o   [$ name ... $]

	   Supported command names are: if, elsif, else, endif, foreach, endforeach, while, endwhile, do, until, var.

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

	   Lexer for [. ... .] 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.

       assembler_rules()
	   Adds mappings from command names used in [$ ... $] tokens to the equivalent Perl syntax.

	     %syntax_rules = $mason->assembler_rules();
