Dancer vs Catalyst [Perl Web Frameworks]
What do you think about both? I began reading a book about Catalyst, and found it pretty complex as compared to Dancer. so now I'm giving Dancer a try, and it looks easier to learn and more "human friendly".
Answer
I think David's comment is very accurate and excellent. However, as someone who has done development in both but is not a developer on either perhaps I can be slightly more objective (and technical) in what the differences are.
Both frameworks provide a variation on the Web MVC paradigm.
Catalyst's main level of abstraction is the Controller. Catalyst expects you to break separate logic out into separate packages in some logical fashion (Login code goes here, Registration code goes there, Search functionality over here). This works incredibly well if you have a team of programmers since each of you can work on separate files and not step all over each other during merges. Catalyst provides a lot of tools for making the Controller logic extensible and flexible, I think the premier example of this is Chained actions which let you split up and build a complex flow for any given request. The downside is that it becomes very seductive to put your business logic into the Controllers and you end up with very fat logic in the Controllers where it (theoretically) belongs in the Model.
Dancer's main level of abstraction is the Route. My experience with Dancer is this leads to much smaller applications. Partly my experience here is tinged with the fact that I have dealt with several thousand line applications in Catalyst but I have yet to write a Dancer app that is longer than 200 lines (with a much smaller scope). I think however that this experience holds true. The push in Dancer is in keeping the Controller logic very thin because it doesn't have the same tools for managing complex behaviors there that Catalyst does.
Honestly I've enjoyed working in both of them. They both provide different opinions on what writing a web application is supposed to be. I would, given the time and inclination, recommend learning both ultimately.
