あと、やはりネットワーク周りなどI/Oの多いプログラムの書きにくさが課題になっている印象。関数的なI/OはFRPで解決できそうな気がするんだけど調べてない。そろそろFRPをちゃんと理解したいなー。 Parsec 3活用事例: Keepalived構文チェッカ - maoeのブログ なんて書いてから早1ヶ月半、ようやくFRPが掴めてきたのでわかったことをまとめてみます。 Reactive programmingって何？ FRPの前に、一般的にwikipedia:en:Reactive programmingと呼ばれるパラダイムについて触れておきます。reactive programmingとは疑似言語を使ってかなーり大雑把に説明すると、 var a = 1 var b = a + 1 a = 10 // aを書き換える print b // => 11print bの出力は2ではなく11です

About the content This content has been published here with the express permission of the author. Promises are a well-known design pattern used to delay evaluation of future values, and to pipeline operations in an asynchronous manner. Typically, there are three internal states used to control the behavior of promises, but there is a lack of core interfaces essential to iOS & OS X development. To

GitHub - gree/observed: Observed is a scripting framework for Ruby which is inspired by reactive programming and flow-based programming. It is created to meet needs of today's scripts: reusability and extensibility, ability to deal with many data sources
Observed is a highly extensible framework for polling applications, middlewares and services running locally or on remote servers. Observed allows you to: poll server(s), optionally modify the response result, pass the result on to other services or trigger other tasks All the above 3 operations are extensible via plugins and can be configured via configuration files. There are plugins available f
※注意 現在のElmは、これを書いた時とはかなり別物になっています。そのためElmを学ぶにはこの資料は適切ではありません。Functional Reactive Programmingの習得には参考になると思います。 ===== ElmはHaskellと同じく純粋関数型言語のひとつで、ブラウザ上で動くアプリケーションの作成に特化しています。目に見えるものがすぐに作れるなど、関数型プログラミングやFRP(Functional Reactive Programming)の入門によい面がいくつかあります。JavaScriptなど型のない手続き型言語に慣れた人向けに関数型プログラミングのイメージを掴んでもらうことを目的にしています。
最近再び Functional Reactive Programming (FRP) について調べているのでまとまり無くメモする。まず大まかな言葉の意味については http://en.wikipedia.org/wiki/Reactive_programming から辿るのが良いと思う。簡単に言うと、FRP とはスプレッドシートの計算モデルを拡張したライブラリや言語、プログラミング技術の事を言う。Function という言葉は付いていたり付いていなかったりするけど、Reactive Programming は副作用を制限する手法なので、どの手法も多かれ少なかれ関数的に使う。 FRP はかなり大雑把に使われる言葉なので人に説明するのが難しい。だけどよく似た粒度の言葉としてはコレクションライブラリくらいが丁度良いと思う。関数プログラミングや論理プログラミングのような大げさな言葉では無い。APL
Bacon.js - Functional Reactive Programming library for JavaScript
What is Bacon.js? A small functional reactive programming lib for JavaScript. Turns your event spaghetti into clean and declarative feng shui bacon, by switching from imperative to functional. It's like replacing nested for-loops with functional programming concepts like map and filter. Stop working on individual events and work with event-streams instead. Transform your data with map and filter.

JavaScriptのFunctional reactive programming(FRP)ライブラリ「Baconjs」を使ってFRPの考え方を勉強してみたメモ。 なお、このメモはFRPの勉強のためにいくつかの資料をざっくりまとめただけなので、Bacon.jsの使い方は解説しない。 なのでBacon.jsの使い方を知りたいだけなら元記事を読んだほうが良い。 Bacon.jsのReadme Bacon.jsのチュートリアルブログ(これとかこれ) 三行で FRPでは従来のプログラミングでは間接的にしか扱えなかった「徐々に変化する値」を第一級のオブジェクトとして扱うことができる。 さらに関数型のcompositionalな性質が合わさって素敵。 Bacon.jsは良いものだ。 従来のプログラミングでは時間とともに変化する値の扱いが難しい 例えば次のフォームの例を考えてみる。 <form> <i

Reactive Programming by UniRx �for Asynchronous & Event Processing This document introduces Reactive Programming and UniRx, which is a Reactive Extensions (Rx) library for Unity. It discusses how Rx allows for better event handling and asynchronous programming in Unity by treating events as observable sequences. UniRx brings the benefits of Rx such as LINQ-style querying and orchestration of event

By: Silk Engineering BlogMarch 19th 2014Writing large JavaScript projects is hard. The language lacks both a type system and a canonical module system, it has a rather clunky syntax and has a threading model that is, to say the least, interesting. No wonder so many third party JavaScript frameworks exist. Luckily JavaScript is a flexible language, which makes extending it easy. As the Silk client

Rihanna's image and music have evolved over her career from innocent to highly sexualized. Her early image portrayed her as young and cheerful while her current image shows her as a dark, sensual woman embracing her sexuality through revealing outfits and explicit lyrics and videos. She values challenging norms and rebelling against expectations of how female pop stars should present themselves. R

Functional Reactive Programming (FRP) integrates time flow and compositional events into functional programming. This provides an elegant way to express computation in domains such as interactive animations, robotics, computer vision, user interfaces, and simulation.
