I'm pleased to announce Mason 2, the first major version of Mason in ten years:
http://search.cpan.org/perldoc?Mason
Mason 2 has been rearchitected and reimplemented from the ground up, to take
advantage of modern Perl techniques (Moose, Plack/PSGI) and to correct
long-standing feature and syntax inadequacies. Its new foundations should allow
its performance and flexibility to far exceed Mason 1.
Though little original code or documentation remains, Mason's core philosophy
is intact; it should still "feel like Mason" to existing users.
Major changes:
* Name. The name is now Mason, instead of HTML::Mason.
* Component classes. Each component is represented by its own (Moose) class,
rather than just an instance of a common class. This means that components have
their own namespaces, subroutines, methods, and attributes, and can truly
inherit from one other. See
http://search.cpan.org/perldoc?Mason::Manual::Components
* Filters. A single powerful filter syntax and mechanism consolidates three
separate filter mechanisms from Mason 1 (filter blocks, components with
content, and escape flags). See
http://search.cpan.org/perldoc?Mason::Manual::Filters
* Plugins. Moose roles are utilized to create a flexible plugin system that can
modify nearly every aspect of Mason's operation. Previously core features such
as caching can now be implemented in plugins. See
http://search.cpan.org/perldoc?Mason::Manual::Plugins
* Web integration. Mason 1's bulky custom web handling code (ApacheHandler,
CGIHandler) has been replaced with a simple PSGI handler and with plugins for
web frameworks like Catalyst and Dancer. The core Mason distribution is now
completely web-agnostic. See
http://search.cpan.org/perldoc?Mason::Plugin::PSGIHandler
* File naming. Mason now facilitates and enforces (in a customizable way)
standard file extensions for components: .m (top-level components), .mi
(internal components), and .pm (pure-perl components).
See http://search.cpan.org/perldoc?Mason::Manual::UpgradingFromMason1 for a
more detailed list of changes.
Mason 2 is obviously still in alpha status, but it has a fair sized test suite
and I'm eager to start building web projects with it. I hope you'll give it a
try and let us know what you think!
Best
Jon
