    sclude

    Scludeは主にHaskellのPreludeにある関数を, TypeScriptかJavaScriptの標準ビルドインオブジェクトのメソッドとして, 持ち込むことを目的としたパッケージです.

    Sclude is a package intended mainly to bring functions in Prelude of Haskell into TypeScript or JavaScript as methods of standard built in objects.

    To Use

    JavaScript

    require('sclude');
     
    console.log([1, 2, 3].subsequences)

    TypeScript

    import "sclude";
     
    console.log([1, 2, 3].subsequences);

    Support language

    Sclude自体はTypeScriptで書かれています. しかしJavaScript(ES2016)以降でも快適に使えるように考えられています. Flowは対応したいですが簡単にやる方法を知らないのでサポートしていません.

    Sclude itself is written in TypeScript. However, it is thought that it can be used comfortably even after JavaScript (ES2016). Flow wants to correspond, but does not support it because it does not know how to do it easily.

    Difference from the original Haskell version

    ScludeはオリジナルのHaskell版のAPIをあまり重視せずに, JavaScript標準オブジェクトのライブラリとの親和性を重視しています.

    例えばinsertByの比較関数compareはenum型Orderingを返さずに, sortとの一貫性を保てるnumberを返します.

    Sclude places great emphasis on compatibility with libraries of JavaScript standard objects without giving much emphasis to the original Haskell version API.

    For example, compare compareinsertBy returns number which maintains consistency withsort instead of returning enum type Ordering.

    TypeScript Optional

    Scludeは typescript-optional のオブジェクトを返り値として使います.

    Sclude is typescript-optional We use the object as a return value.

    Why do I write Sclude

    JavaScriptはtakeWhileなど基本的なアルゴリズム関数を欠いていて,とても面倒です.

    JavaScript lacks basic algorithm functions such as takeWhile, which is very troublesome.

    Why do not I use Lodash

    Lodashは良いライブラリですが, 標準ライブラリがメソッド記法を使っているなら, 統一してメソッド記法を使いたい.

    Lodash is a good library, but if the standard library uses method notation, I would like to use method notation consistently.

    Bad thing is to extend the prototype

    prototypeを拡張する以外に良い方法があれば私もそうしていました. しかし今のJavaScriptにはモジュールがありますし, TypeScriptを使えば被さりはチェック出来るので昔よりは行って良いと判断しました. これはMikutterなら普通のことです.

    If there was a good way to extend prototype, I did as well. But now JavaScript has modules, If you use TypeScript you can check cloudiness so it might not be better than before. This is normal for Mikutter.

    There is no method that

    TypeScriptで型安全にメソッド記法で実装する方法がわからないメソッドは実装していません. 方法がわかったら実装します.

    I do not implement those that do not know how to type safely in TypeScript by method notation. I implement if I know how.

    There are other similar libraries though

    ScludeがTypeScriptでHaskellのライブラリをどこまで再現できるのか実験した副産物というのは否定できません.

    I can not deny that Sclude is a by-product that I experimented with TypeScript to see how far I can reproduce Haskell 's library.
