=head1 NAME
Text::MicroMason::ServerPages - Alternate Syntax like ASP/JSP Templates
=head1 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 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' ) { %>
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 %>!
<% } %>
=head1 DESCRIPTION
This subclass replaces MicroMason's normal lexer with one that supports a syntax similar to Active Server Pages and Java Server Pages.
=head2 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:
=over 4
=item *
Angle-bracket markup tags
=back
The following syntax features of are B<not> supported:
=over 4
=item *
Dynamic XML/XSL processing.
=item *
Web server objects such as $Session, $Request, $Response, and $Application.
=item *
Application events such as Application_OnStart, Script_OnStart, and other gloga.asa features.
=back
=head2 Template Syntax
The following elements are recognized by the ServerPages lexer:
=over 4
=item *
E<lt>% perl statements %E<gt>
Arbitrary Perl code to be executed at this point in the template.
=item *
E<lt>%= perl expression %E<gt>
A Perl expression to be evaluated and included in the output.
=item *
E<lt>%& file, arguments %E<gt>
Includes an external template file.
=item *
E<lt>%-- comment --%E<gt>
Documentation or inactive code to be skipped over silently. Can also be used to quickly comment out part of a template.
=item *
E<lt>%I<name>E<gt> ... E<lt>/%I<name>E<gt>
Supported block names are: 'perl', 'args', 'once', 'init', 'cleanup', and 'doc'.
=back
=head2 Private Methods
=over 4
=item 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.
=back
