# distributed-closure
[](https://buildkite.com/tweag-1/distributed-closure)
Leverage the `-XStaticPointers` [extension][staticpointers-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][ocharles-static-pointers] for a hands on introduction
and [this paper][ch-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
```Haskell
data NodeId
-- Assume we're given a spaw primitive.
spawn :: NodeId -> Closure (IO ()) -> IO ()
-- A computation to remote on another node.
hello :: String -> IO ()
hello name = putStrLn ("Hello, " ++ name)
main = do
name <- getLine
spawn "someAddress" (static hello `cap` name)
```
An example of sending static pointers and closures
through a communication channel is provided under
[examples/ClientServer.hs](examples/ClientServer.hs)
in the source repository.
`distributed-closure` does not implement sending/receiving/spawning
closures - that's left for higher-level frameworks. Only closure
creation, composition and (de)serialization.
