Effective Concurrency with Algebraic Effects · KC Sivaramakrishnan
Algebraic effects and handlers provide a modular abstraction for expressing effectful computation, allowing the programmer to separate the expression of an effectful computation from its implementation. In this post, I will present an extension to OCaml for programming with linear algebraic effects, and demonstrate its use in expressing concurrency primitives for multicore OCaml. The design and im
Eff Programming Language
Eff is a functional programming language based on algebraic effect handlers. This means that Eff provides handlers of not only exceptions, but of any computational effect, allowing you to redirect output, wrap state modifications in transactions, schedule asynchronous threads, and much much more… Try it out in your browser! or install it on your computer Algebraic effects, on which Eff is built, g

This package implements extensible effects, an alternative to monad transformers. The original paper can be found at http://okmij.org/ftp/Haskell/extensible/exteff.pdf. The main differences between this library and the one described in the paper are that this library does not use the Typeable type class, does not require that effects implement the Functor type class, and has a simpler API for hand
PureScript Community Blog - Handling Native Effects with the Eff Monad
Posted on March 16, 2014 by Phil Freeman In this post, I’m going to talk about PureScript’s hybrid approach to handling side-effects. As in Haskell, values in PureScript do not have side-effects by default, and there are a number of techniques for handling “non-native” side-effects. Such techniques include the use of things like monoids, monads, applicative functors and arrows, but I’m not going t
24 Days of Hackage: extensible-effects
To a lot of programmers, the idea of programming with monads is almost synonymous with the idea of programming in Haskell. Of course, to those us who write a lot of Haskell we only consider monads a small part of our work - but it’s true, monads do have a fairly important role in how we structure our computations. Despite the benefits monads give us, they are not without their pain points. For a l
Extensible Effects はモナド変換子に対する救世主になり得るか？
Extensible Effects はモナド変換子に対する救世主になり得るか？ konn-san.com Oleg, Sabry and Swords らによる Extensible Effects: An Alternative to Monad Transformers の論文を読んだメモ的な何かです。モナド変換子に関する簡単な現状確認から入ってはいますが、想定読者層は日常的にモナドやモナド変換子を用いたプログラムを書いている人達です。 どちらかというと自分向けのメモの性格が強いので、詳しい部分は論文を参照してみてください。 背景：モナド変換子とその問題 Haskell を中心に、関数型言語では副作用のある函数を合成するための手段としてモナドが広く用いられている。モナドは非常に強力な抽象化で、およそ副作用と呼べるものはモナドを使って定式化することが出来た。例えば、大域的な環境 r を
