Hello, I'm trying to add storage to my library (HackaMol), and I think I'm close to getting it to work. My library depends on a non-moose class (Math::Vector::Real), which I was able to get serialized:
http://stackoverflow.com/questions/6101800/store-a-moose-object-that-has-a-pdl-as-an-attribute/31005543#31005543 Any attributes that are Math::Vector:Real objects serialize, unless they are an additional level below in the object, e.g. (ArrayRef[Math::Vector::Real]) In the script below (along with runtime errors) I can store and load the HackaMol::Atom if I remove the coords attribute. The coords attribute has Array traits for storing large numbers of atomic configurations, a characteristic that is central to HackaMol. you can see what I added to get the storage to sorta work here: https://github.com/demianriccardi/HackaMol/commit/384ceb9ce3749d6342fc54df292182442764d180 you'll notice the strange add_custom_type_handler( '[Math::Vector::Real]' which was a step I was hoping would bring me closer. Is there a way to get this to work? Thanks!
