Configuration files, on the other hand, are not meant to be written with a programming language.
who says so? I use PDL (Perl Data Language), a highly complex and powerful software, probably the most complex I have ever used, and all its configuration required to build it are done using a extremely readable perl data structure.
Well, Dancer has been written with one main idea in mind: everything should be simple and intuitive. If there is one reason why people like Dancer, it's because of that: it's simple, intuitive and elegant. YAML configuration files contribute to that, it's very handy to just drop a list of key/value pairs in one config.yml file and just start working. Of course you can find many examples of applications whose configuration files are written with a programming language, but I dislike that. Because if you let the user write his configuration files with a script, sooner or later someone will start putting code inside, and that's a pandora box.
YAML is a very good and well-kown format for human-readable configuration files.
Again, who says so? citations?
My experience tells me that. Again, if you want to write pure perl Dancer settings, you can do it. YAML files are there for people who want to keep their settings outside of their code.
Besides, who wants human-readable? I want programmer-readable. No human reads the config files on a daily basis, but my computer does all the time. I just gave you an example above where a simple indentation can cause misunderstanding both to the human and the computer.
I precisely want human-readable here. Again, Dancer is meant to be as easy to handle as possible. It's a key feature. You won't make me change my mind on this ;) Of course, if you really like, you can write a plugin that will do what you want. Regards, -- Alexis Sukrieh
