Things are moving in the Acceleo community. First of all, Acceleo 2 is out and provides a big place for modules like Wisss. To take advantage of the buzz, I’ve finally written the official acceleo page for Wisss. I’ve also comited all my changes in the SVN even if it doesn’t work as well as my first attempt.

But what interests me above all is the publication of the advanced documentation. I’d rather continue to code but I will first read it. So much time I wait for it I hope understanding new things, avoid mistakes while it’s not too late.

For those who read this post (if ever there are) and don’t want to look at the SVN or don’t understand what I am doing, I’m currently working on the PHP generator, especilly on the object manager and the call order between business object and persistense ones. I’ve defined three ways to get an object back from the database : atomic (only the object, with id for associated objects), summary (get only useful information from the object and its related objects, will probably be user code) and full (get all information and related objects).

I try to make everything in the object manager, to have a central place to make choice and thus experiment optimization and auto-detection for what to load. But I lose my way because I don’t manage to make a choice in my Php architecture and I don’t know which layer should instanciate objects from the other.

Even if I’ve simplified my metamodel regarding to the previous version, concerning the generator I’m affraid to try something really too complex for what Php can do. I’ll see. If the metamodel is right, it’s already a very good thing.

I’ll be back ! (after reading Obeo’s documentation )
