distributed-closure

Leverage the -XStaticPointers extension from GHC 7.10 onwards for distributed programming using lightweight serializable closures. This package implements a serializable closure abstraction on top of static pointers. Serializable closures can be shipped around a computer cluster. This is useful for implementing intuitive and modular distributed applications. See this blog post for a hands on introduction and this paper for the original motivation.

Example

In GHC 8 and above, remoting a computation on another node using this library goes along the lines of

hello :: String -> IO ()
hello name = putStrLn ("Hello, " ++ name)

main = do
  name <- getLine
  spawn "someAddress" (static hello `cap` name)

distributed-closure does not implement sending/receiving/spawning closures - that's left for higher-level frameworks. Only closure composition and (de)serialization.
