bryan over at Pipedot has released the source code for Pipecode, the software running pipedot.
Pipecode is written in PHP and the code is using the GPLv3.
your argument is based on the false premise that templating is required for flexibility... it's not. if you look at the source, the page structure can be changed, quite easily too. the only difference is that you need only know a bit of php to do it and not some obscure invented templating syntax.
separation of layers is usually good, but it's not the rule, and nor should it be... because such rule itself would remove flexibility. established rules are a tool of the waterfall trade, and is also partly why waterfall projects so often fall on their swords.
do grab the code. "professional programmers" will no doubt balk at it, but from a pragmatic tinkerer's point of view, it's simple, easy to read & understand, and it works.i was able to navigate my way around pipecode fairly easily the first time i saw it. slashcode otoh, well... you can probably guess.
Nope, my argument is that proper structuring of code makes it easier to add/remove/change. Improper design makes changes harder (hence, removes flexibility) and your options fewer.
Is your argument that "templating" is something you do in "one of those (obscure invented) templating languages"? Do you believe that PHP isn't/can't be a templating language? Is Velocity or Freemarker "obscure" or does it have to have the ubiquity of JS?
Just so we are clear, I am talking about the MVC pattern - specifically the Model->View part, templating is simply mapping the data in the Model to structures in the View. Proper templating treats those a separate components so you can (re)move, add, enhance what the user sees without needing to or minimize messing with code. Ignoring the business driven decisions by Dice, do you think we would be here if the site-which-must-not-be-named had a clean template layer that you could control?
Ah, so design patterns (MVC in this case) is a tool of the Man, and fails the People in the real world of Agile Masters. I won't get side-tracked on why waterfall and agile projects fail, but it isn't because they followed best practices. In fact, many of these "rules" were created to address project failure regardless of methodology - but likely help the faster paced development teams the most.
I grabbed slashcode when I joined this site, and it is sitting on my computer. I meandered through it, mostly because I was interested in seeing what NCommander was talking about in some of those posts. It is a good sign that the pipedot code is easy to understand, but I just did a bender with Wordpress, so I'm not in any particular hurry to look at more PHP - but I definitely plan to. Eventually. When the mood or need strikes me.
i'm just a tinkerer... rules are meant to be broken, wheels are meant to be reinvented, and methodologies be damned. also, my idea of software design is scrawl on a bunch of sticky notes, so it's probably a good thing i'm not a pro.
