The GHC API requires writing the code evaluation model from scratch. This is a complicated task. iHaskell reimplements a lot of GHCi directives (so notebooks can be GHCi compatible) but doesn’t cover a lot of useful ones e.g :set package and :script. For this reason, Sabela evaluates the code with a cabal subprocess. This ensures that you get all of GHCi’s API for free.

For each key in the incoming state, we get the local register at that key. If we find one, the peer is updating an existing key that we already know about, so we call that register’s merge method with the incoming state at that key. Otherwise, the peer has added a new key to the map, so we instantiate a new LWW Register using the incoming state at that key.
