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

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 $]

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

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.

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();
    

For an overview of this templating framework, see Text::MicroMason.
This is a mixin class intended for use with Text::MicroMason::Base.
