Catalyst::Model::FormFu has just hit CPAN. It is an experimental alternative interface to HTML::FormFu for Catalyst and its main puprpose is to provide improved performance over the existing Catalyst::Controller::HTML::FormFu. It parses the form configuration files and loads form objects during application startup, and then returns clones of these objects inside your actions. It is hard to evaluate precisely the performance boost that this provides (disk access speed will vary, and there is always the Catalyst overhead), but my crude benchmarks indicate that you can expect a form object to be loaded at least twice as fast when using Catalyst::Model::FormFu.

Making a clean break from what draws you back is important. Whither can we go if "Perl 5" has lost its coolness factor, and "Perl 6" is already taken? But the path to world domination and greater numbers of "ninja perl programmers" and "perl rockstars" need not not necessarily go through the name of Perl itself. It did not for Ruby - it was Rails that did it. Here is my recipe:

chromatic wrote about setting up a private CPAN to store your code. I am a big fan of this appropach, and I think that managing code as distributions, rather than as a bunch of stuff in a version control repo (which is the predominant practice in most shops), is the one and only way to go. Here is how we have set things up at $work:

MooseX::Params (my experiment in parameter processing) has undergone some changes and only the the attributes-based interface has been left now. Here are some examples from the synopsis of how it works. Most of them have been adapted from the Moose manual and the subroutines chapter of Gabor Szabo's Perl 6 tutorial.

This is a follow-up to my previous post at http://mechanicalrevolution.com/blog/parameter_apocalypse.html.

After experimenting with a lot of different ways to tackle method and parameter declaration, I think I have finally settled on an attributes-based interface that makes for a decent compromise between usability and compatibility. The examples blow describe the proposed interface. Note that only the :Args attribute is currently implemented.

An alpha versin of MooseX::Params, described in my previous post, is already on CPAN. MooseX::Params is an attempt to rethink parameter processing and function declaration in Perl. The current release implements the three main objectives: a meta protocol, parameters with lazy builders, and access to processed parameters via the %_ hash.
