Changed description
from This is an extensible effects library for Haskell taking inspiration from the Eff language <http://www.eff-lang.org/>.
See these papers for the ideas and theory behind the library:
- O. Kammar et al: Handlers in Action! <http://homepages.inf.ed.ac.uk/slindley/papers/handlers.pdf>
- A. Bauer, M. Pretnar: Programming with Algebraic Effects and Handlers <http://arxiv.org/abs/1203.1539>
- O Kiselyov, A Sabry, C Swords: Extensible Effects <http://dl.acm.org/citation.cfm?id=2503791>
Implementation wise it's most close to @extensible-effects@ <http://hackage.haskell.org/package/extensible-effects> (also see the Extensible Effects paper) but it implements deep handlers instead of shallow.
@
import Control.Effects.Cont.Eff
import Control.Effects.Cont.Reader
import Control.Effects.Cont.Exception
program = do
v <- ask
if v < 15
then throw $ show v
else return (v+1)
run n = runPure . handle exceptionHandler . handle (readerHandler n)
res :: Integer -> Either String Integer
res n = run n program
