NAME

Text::MicroMason::ServerPages - Alternate Syntax like ASP/JSP Templates

SYNOPSIS

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

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

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

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

Server Pages syntax provides another way 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 %>!
    <% } %>

DESCRIPTION

This subclass replaces MicroMason's normal lexer with one that supports a syntax similar to Active Server Pages and Java Server Pages.

Compatibility with Apache::ASP

Apache::ASP 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 Apache::ASP, 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:

• Angle-bracket markup tags

The following syntax features of are not supported:

• Dynamic XML/XSL processing.

• Web server objects such as $Session, $Request, $Response, and $Application.

• Application events such as Application_OnStart, Script_OnStart, and other gloga.asa features.

Template Syntax

The following elements are recognized by the ServerPages 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.

• <%& file, arguments %>

  Includes an external template file.

• <%-- comment --%>

  Documentation or inactive code to be skipped over silently. Can also be used to quickly comment out part of a template.

• <%name> ... </%name>

  Supported block names are: 'perl', 'args', 'once', 'init', 'cleanup', and 'doc'.

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.
