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();

NAME

       Text::MicroMason::DoubleQuote - Minimalist Interpolation Engine

SYNOPSIS

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

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

       Templates can be written using Perl's double-quote interpolation syntax:

	   $coderef = $mason->compile( text => 'Hello $ARGS{name}!' );
	   print $coderef->( name => 'World' );

DESCRIPTION

       Text::MicroMason::DoubleQuote uses Perl's double-quoting interpolation as a minimalist syntax for templating.

       Of course you don't need this module for simple cases of interpolation, but if you're already using the MicroMason framework to process
       template files from disk, this module should allow you to make your simplest templates run even faster.

       To embed values other than simple scalars in a double-quoted expression you can use the ${ expr } syntax. For example, you can interpolate
       a function call with "${ ( time() ) }" or "@{[mysub(1,2,3)]}". As noted in perldaq4, "this is fraught with quoting and readability
       problems, but it is possible." In particular, this can quickly become a mess once you start adding loops or conditionals. If you do find
       yourself making use of this feature, please consider switching to one of the more powerful template syntaxes like
       Text::MicroMason::HTMLMason.
