Into The Blue

Posted on 7th May 2011

I haven't been posting recently about the Perl projects I'm currently working on, so over the next few posts I hope to remedy that.

To begin with, one of the major projects I've been involved with for the past 8 years has been CPAN Testers, although you can find out more of my work there on the CPAN Testers Blog. This year I've been releasing the code that runs some of the websites, specifically those that are based on my other major project, Labyrinth. Spearheading these releases have been the CPAN Testers Wiki and CPAN Testers Blog, with further releases for the Reports, Preferences and Admin sites also planned. The releases have taken time to put together mostly because of the major dependency they all have, which is Labyrinth.

Labyrinth is the website management framework I started writing back in 2002. Since then it has grown and become a stable platform on which to build websites. With both the CPAN Testers Wiki and the CPAN Testers Blog, three key plugins for Labyrinth have also been released which hopefully others can make use of.

The Wiki plugin, was intended to be written for the YAPC::Europe 2006 Wiki, but with pressures of organising the conference and setting up the main conference site (which also used Labyrinth), I didn't get it finished in time. Once a CPAN Testers Wiki was mooted, I began finishing off the plugin and integrating into Labyrinth. The plugin has been very stable for the last few years, and as a consequence was the first non-core plugin to be released. It's a fairly basic Wiki plugin, not too many bells and whistles, although there are a couple of Perlish shortcuts, but for the most part you don't need them. The CPAN Testers Wiki codebase release was also the first complete working site for Labyrinth, which was quite a milestone for me.

Following that success, the next release was for the CPAN Testers Blog. Again the underlying plugin, the Blog Plugin, has been stable for a few years, so was fairly quick to package and release, however the secondary plugin, the Event Plugin, has been evolving for quite some time and took a little more time. As I use both these plugin for several other sites, it was a good opportunity to bring together any minor bug fixes and layout changes. Some of these have seen slight modifications to the core Labyrinth codebase and the core set of plugins. In addition it has prompted me to start working on the documentation. It is still a long way from being complete, but at least the current documentation might provide some guidance to other users.

One of my major goals for Labyrinth was for it to be a 'website in a box'. Essentially this means that I wanted anyone to take a pre-packaged Labyrinth base (similar to the Demo site), drop it on a hosting service and be able to run a simple installation script to instantiate the database and configuration. The installation would then also be able to load requested plugins, and amend the database and configuration files appropriately. I haven't got to that stage yet, but it is still a goal.

With this goal in mind, I have read with interest the recent postings regarding the fact that DotCloud are now able to run Perl apps. This is definitely great news, and is exactly the kind of setup I had wanted to make best use of for the 'website in a box' idea. However, with several other frameworks now racing to have the coolest instance, it isn't something I'm going to concentrate on right now for Labyrinth. Plus there is the fact that Labyrinth isn't a PSGI framework, which others have eagerly added to their favourite framework. Labyrinth came from a very different mindset than other now more well known frameworks, and tries to solve some slightly different problems. With just me currently working on Labyrinth, as opposed to the teams of developers working on other frameworks, Labyrinth is never going to be the first choice for many reasons. I shall watch with interest the successes (and lessons learned from any hiccups) of the other frameworks as it is something I would like to get working with Labyrinth. If anyone who has the time and knows PGSI/Plack well enough, and would like to add those capabilities to Labyrinth, please get in touch.

The next notable plugins I'll be working on are the Survey, Music and Gallery Plugins. The former has its own post coming shortly. The next notable CPAN Testers site released planned is the Reports site. With it being considerably more involved, it might take a little longer to package and document, but it will likely be the most complex site release for Labyrinth, which will give anyone interested in the framework a good idea of how it can be used to drive several sites all at once.
