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 evaluate 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:

       •   Square-bracket markup tags

       The following syntax features of are not supported:

       •   Dynamic HTML tags

   Template Syntax
       The following elements are recognized by the Embperl 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.

       •   [! perl statements !]

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

       •   [$ 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();
