Haskell Advent Calendar jp 2010のためのエントリです（17日目）． 6日目の id:camlspotterさんの 経験15年のOCaml ユーザーが Haskell を仕事で半年使ってみた に対するカウンター（になってるかどうか分からないですが）みたいな感じです． 近くて遠い隣人：HaskellとOCaml OCamlはHaskellと違って副作用があり，更にHM型推論をもつためプログラマは本質的な部分の記述に注力しつつ，コードのチューニングもできる． つまり働くHaskellプログラマがシリアスなソフトウェアを書く時に使えるほとんど唯一の選択肢だ．しかし，同じ静的型付けの関数型言語でありながら，OCamlとHaskellの見た目はかなり異なる． この記事では， HaskellプログラマがOCamlを使い始めると，どういうトラップにハマるかを書く． なかでも，
Reflex adapts to changes in your...DataReflex apps automatically react to changing data. This keeps every interaction current, accurately representing the relationship between your data and the real world. Reflex is the key to writing self-updating user interfaces. RequirementsReflex components are modular and reusable. If your requirements change, your app can quickly and easily be reworked. The
What is Eta? Eta is a pure, lazy, strongly typed functional programming language on the JVM. It brings two big ecosystems, the JVM and Haskell, together. This allows you to harness the best of both ecosystems to build your applications quickly and effectively. Eta's concurrency support helps you to build highly scalable systems.
Historically, I’ve struggled to find a concise, simple way to explain what it means to practice type-driven design. Too often, when someone asks me “How did you come up with this approach?” I find I can’t give them a satisfying answer. I know it didn’t just come to me in a vision—I have an iterative design process that doesn’t require plucking the “right” approach out of thin air—yet I haven’t bee
今までいまいちモチベが上がらなかったHaskellでスクリプトを書くというのが、急に現実的になってしまったので、紹介します。 Haskellでスクリプティングする上での問題点 Haskellはもともと簡単なテキスト処理を書きやすいプログラミング言語ではあるのですが、標準で提供されているライブラリはあまり多くないので、必要に応じてコミュニティーパッケージを導入しなければその力を存分に発揮することができません。 通常のパッケージなら、cabalに依存関係を書けばパッケージマネージャで自動的に（コケることもありますが、理想的には）管理できるのですが、シェルスクリプトやPerl、あるいは最近ならPythonでやるような、コードを直接インタプリタで実行するような形のコードでは、そのような依存関係を自動で解決することは難しく、その上、仮にやろうとしたところで、いつまでもその依存パッケージが新しいコンパ
Employment At this time we are not accepting any new applications; however if you submit an application we will review it in our next round of hiring which is estimated to be in Q3, 2013. Do you love Haskell? Do you like problem solving and finding elegant solutions? Are you not opposed to making money? Tsuru is a fast growing company looking to expand its team. Ideally candidates should enjoy wha
These are Haskell translations of Ninety-Nine Lisp Problems, which are themselves translations of Ninety-Nine Prolog Problems. If you want to work on one of these, put your name in the block so we know someone's working on it. Then, change n in your block to the appropriate problem number, and fill in the <Problem description>,<example in Haskell>,<solution in haskell> and <description of implemen
Haskell has a diverse range of use commercially, from aerospace and defense, to finance, to web startups, hardware design firms and a lawnmower manufacturer. This page collects resources on the industrial use of Haskell. The main user conference for industrial Haskell use is CUFP - the Commercial Users of Functional Programming Workshop. The Industrial Haskell Group supports commercial users. Ther
CodeWorld is an educational environment using Haskell. It provides a simple mathematical model for geometric figures, animations, and interactive and multi-player games. The web-based programming environment supports this educational mission with a zero-setup editor and compiler, easy sharing and cloud storage of projects, and the ability to run programs right in the web browser using GHCJS. There
If you need to convert files from one markup format into another, pandoc is your swiss-army knife. Pandoc can convert between the following formats: (← = conversion from; → = conversion to; ↔︎ = conversion from and to) Lightweight markup formats ↔︎ Markdown (including CommonMark and GitHub-flavored Markdown) ↔︎ reStructuredText → AsciiDoc ↔︎ Emacs Org-Mode ↔︎ Emacs Muse ↔︎ Textile → Markua ← txt2t
Introductions to Haskell These are the recommended places to start learning, short of buying a textbook. See also Meta-tutorial, another, shorter overview of tutorials aimed at helping you find the right one. Best places to start Introduction to Haskell (Spring 2013) An excellent tutorial to Haskell for beginners given as a course at UPenn by the author of the Typeclassopedia and Diagrams, Brent Y

What is Snap? Snap is a simple web development framework for unix systems, written in the Haskell programming language. Snap has a high level of test coverage and is well-documented. Features include: A fast HTTP server library A sensible and clean monad for web programming An HTML-based templating system for generating pages Snaplets Snap includes an optional system for building reusable pieces w
In mathematics, amongst the natural numbers greater than 1, a prime number (or a prime) is such that has no divisors other than itself (and 1). This means that it cannot be represented as a product of any two of such numbers.

TL;DR 簡潔で直感的に扱える、宣言的なRust向けのコマンドライン引数パーザーを作りました。 https://crates.io/crates/argopt モチベーション Rustにstructoptというライブラリがあります。これはコマンドライン引数をパーズするライブラリなんですが、僕はこのライブラリが大好きなんです。Rustのライブラリの中で一二を争うほど好きです。なんならコマンドラインツールをRustを書く理由の大部分がこのライブラリの存在といっても過言ではないかもしれません（過言ですけど）。 しかしstructoptも使い続けていると、どうにももっと便利にできるんじゃないのかと思う部分が出てきます。structoptでは名前の通りコマンドライン引数をstructで定義して、それに#[derive(StructOpt)] とStructOptをderiveすることでパーザーのコ
