=head1 NAME

Text::MicroMason::QuickTemplate - Alternate Syntax like Text::QuickTemplate


=head1 SYNOPSIS

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

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

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

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

Or use Text::QuickTemplate's calling conventions:

    $template = Text::MicroMason->new( -HTMLTemplate, text=>'simple.tmpl' );
    print $template->fill( %arguments );

Text::QuickTemplate provides a syntax to embed values into a text template:

    Good {{timeofday}}, {{name}}!


=head1 DESCRIPTION

This mixin class overrides several methods to allow MicroMason to emulate
the template syntax and some of the other features of Text::QuickTemplate.

This class automatically includes the following other mixins: TemplateDir, HasParams, and StoreOne.

=head2 Compatibility with Text::QuickTemplate

This is not a drop-in replacement for Text::QuickTemplate, as the implementation is quite different, but it should be able to process most existing templates without major changes.

The following features of EmbPerl syntax are supported:

=over 4

=item *

Curly bracketed tags with parameter names.

=item *

Array of parameters hashes.

=item *

Special $DONTSET variable.

=back


=head1 SEE ALSO

The interface being emulated is described in L<Text::QuickTemplate>.

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

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

For distribution, installation, support, copyright and license 
information, see L<Text::MicroMason::Docs::ReadMe>.
