A quick glance at the sources and I see where missing a little bit
(but not much)...
Internally, Adam operates on adobe::value_t for the values in cells
(these are similar to boost any - but the type requirements are a bit
stronger, the type passed to a value_t must be equality comparable
and if ADOBE_SERIALIZATION is defined then it must support operator
<< on an ostream. The serialization should go through the Adobe
formatting code (but that's a loose requirement) -
ADOBE_SERIALIZATION predates the boost serialization code but it
isn't complete and although I like some of the ideas better we'll
likely replace it with boost serialization. For now, it is only used
for debugging.
The virtual machine has a pair of callbacks for user defined
functions (one which takes named parameters and hands off a
dictionary_t, and one that takes unnamed parameters and hands off an
array_t) -
So all you need to do is write the functions you need for your dates
in terms if the function interface for the virtual machine - and plug
it in to the (non-existent but trivial to add) interface to Adam.
Programatically, you can set any value_t into an Adam sheet and it
will carry through calculations (the type system is open).
I don't yet have operator overloading (working on how you recover an
"any addable type" from an "any type"). A long term goal is to
eliminate the dependency tracking in the VM and then the interface to
Adam will be simple function objects (instead of "byte codes" in an
array_t).
