NAME

       Mason::Manual::Subclasses - Creating custom subclasses of Mason's classes

DESCRIPTION

       You can subclass the following Mason classes for your application:

	   Mason::CodeCache
	   Mason::Compilation
	   Mason::Component
	   Mason::Component::ClassMeta
	   Mason::Component::Import
	   Mason::Component::Moose
	   Mason::Interp
	   Mason::Request
	   Mason::Result

       and arrange things so that Mason always uses your subclass instead of its default class.

       Note: if you want to create a general purpose modification to Mason to use in multiple applications, you should probably create a plugin
       instead of a subclass.

CREATING A SUBCLASS

       A subclass should look something like this:

	   package My::Mason::Interp;
	   use Moose;
	   extends 'Mason::Interp';

	   # put your modifications here

	   1;

LETTING MASON KNOW ABOUT YOUR SUBCLASSES

       There are two ways to let Mason know about your subclasses: by naming convention, and by parameters to "Mason->new".

   By naming convention
       First, create a subclass of Mason itself:

	   package My::Mason;
	   use Moose;
	   extends 'Mason';

	   1;

       and use that in place of "Mason" in construction:

	   my $interp = My::Mason->new();

       Now, you can place any subclasses under 'My::Mason' and they'll automatically be picked up. e.g.

	   My::Mason::Compilation
	   My::Mason::Interp
	   My::Mason::Request

By constructor parameter
       You can specify your subclasses via "base_*" parameters to "Mason->new()".  e.g.

	   my $interp = Mason->new(
		base_compilation_class => 'My::Mason::Compilation',
		base_interp_class => 'My::Mason::Interp'
		base_request_class => 'Some::Other::Mason::Request'
	   );

       See "CUSTOM MASON CLASSES" in Mason::Interp for a complete list.

NAME

       Mason::Plugin::DollarDot - Allow $. as substitution for $self-> and in attribute names

SYNOPSIS

	   <%class>
	   has 'name';
	   has 'date';
	   </%class>

	   <%method greet>
	   Hello, <% $.name %>. Today is <% $.date %>.
	   </%method>

	   ...
	   % $.greet();

	   <%init>
	   # Set the date
	   $.date(scalar(localtime));
	   # or, if combined with LvalueAttributes
	   $.date = scalar(localtime);
	   </%init>

DESCRIPTION

       This plugin substitutes "$.identifier" for "$self->identifier" in all Perl code inside components, so that $. can be used when referring to
       attributes and calling methods. The actual regex is

	   s/ $.([^Wd]w*) / $self->$1 /gx;

RATIONALE

       In Mason 2, components have to write "$self->" a lot to refer to attributes that were simple scalars in Mason 1. This eases the transition
       pain.  $. was chosen because of its similar use in Perl 6.

       This plugin falls under the heading of gratuitous source filtering, which the author generally agrees is Evil. That said, this is a very
       limited filter, and seems unlikely to break any legitimate Perl syntax other than use of the $. special variable (input line number).

BUGS

       Will not interpolate as expected inside double quotes:

	   "My name is $.name"	 # nope

       instead you have to do

	   "My name is " . $.name
