multi-component infrastructure. #16

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
We have the following current problems:

* happs-state requires too many type signatures that are also hard to
understand for a variety of simple components e.g. the Timer example

* you can't have two states of the same type in your app which is useful
both for testing and for multihome style apps

* ixset doesn't work with current state because is has floating parameters

The solution is to have query and update take a state index value as the
first argument e.g.

$(systemState [("StateKeyOne",''StateOne)])

then lets you do things like:

  query StateKeyOne $ getSession sessionKey

also startState should take a config object to allow specification of a 
different
directory.

It should be noted that multi-state is equally hard to maintain as single-state.

We're going for a multi-component infrastructure instead.
