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:

•

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();
