# 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](https://en.wikipedia.org/wiki/Tuple_space). 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](http://racket-lang.org/) implementation of Syndicate

   (plus auxiliary modules) in `racket/syndicate/`

 - an

   [ECMAScript 5](http://www.ecma-international.org/publications/standards/Ecma-262.htm)

   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/`
