Tony Garnock-Jones 463dd48577 Always pick the highest-priority script to run next. 
This means that `*gc-priority*` scripts will now reliably run last.
Prior to this change, if some higher-priority script X ran while a
`*gc-priority*` script Y was queued, and it enqueued a high-priority
script Z, then Y would run before Z.

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.

Contents

This repository contains

  • a Racket implementation of Syndicate (plus auxiliary modules) in racket/syndicate/

  • an ECMAScript 5 implementation of Syndicate in js/

  • larger example programs:

    • examples/platformer, a 2D Platform game written in Syndicate for Racket.

    • examples/netstack, a TCP/IP stack written in Syndicate for Racket. It reads and writes raw Ethernet packets from the kernel using Linux- and OSX-specific APIs.

  • a sketch of a Haskell implementation of the core routing structures of Syndicate in hs/
