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



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 evalute 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 ) {  %>
      Im sorry <%= $name %>, Im afraid I cant do that right now.
    <% } else {
        my $hour = (localtime)[2];
        my $daypart = ( $hour > 11 ) ? afternoon : morning;
      Good <%= $daypart %>, <%= $name %>!
    <% } %>


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:
o Angle-bracket markup tags
The following syntax features of are <B>notB> supported:
o Dynamic XML/XSL processing.
o Web server objects such as $Session, $Request, $Response, and $Application.
o Application events such as Application_OnStart, Script_OnStart, and other gloga.asa features.

    Template Syntax

The following elements are recognized by the ServerPages 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 <%& file, arguments %>

Includes an external template file.

o <%-- comment --%>

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

o <%name> ... </%name>

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

    Private Methods


  ( $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.


For an overview of this templating framework, see Text::MicroMason.

This is a mixin class intended for use with Text::MicroMason::Base.
