Syndicate: A Networked, Concurrent, Functional Programming Language
Syndicate is an actor-based concurrent language able to express communication, enforce isolation, and manage resources. Network-inspired extensions to a functional core represent imperative actions as values, giving side-effects locality and enabling composition of communicating processes.
Collaborating actors are grouped within task-specific networks (a.k.a. virtual machines) to scope their interactions. Conversations between actors are multi-party (using a publish/subscribe medium), and actors can easily participate in many such conversations at once.
Syndicate makes presence notifications an integral part of pub/sub through its shared dataspaces, akin to tuplespaces. Each shared dataspace doubles as the pub/sub subscription table for its network. Actors react to state change notifications reporting changes in a dataspace, including new subscriptions created by peers and removal of subscriptions when a peer exits or crashes. State change notifications serve to communicate changes in demand for and supply of services, both within a single network and across nested layers of networks-within-networks. Programs can give up responsibility for maintaining shared state and for scoping group communications, letting their containing network take on those burdens.
