The Unison language
Unison is a new programming language, currently under active development. It's a modern, statically-typed purely functional language, similar to Haskell, but with the ability to describe entire distributed systems with a single program. Here's an example of a distributed map-reduce implementation:
-- comments start with `--` mapReduce loc fn ifEmpty reduce data = match split data with Empty -> ifEmpty One a -> fn a Two left right -> fl = at loc '(mapReduce loc fn ifEmpty reduce !left) fr = at loc '(mapReduce loc fn ifEmpty reduce !right) op !fl !fr
This function can be either simulated locally (possibly with faults injected for testing purposes), or run atop a distributed pool of compute.
We are currently alpha testing Unison. If you'd like to participate in alpha testing, you can go to the docs site to get started.
Building using Stack
If these instructions don't work for you or are incomplete, please file an issue.
$ git clone https://github.com/unisonweb/unison.git $ cd unison $ stack --version # we'll want to know this version if you run into trouble $ stack build && stack exec tests && stack exec unison
