PureScript 0.6.8 发布，静态类型语言

#JetBrains 六折贺新春！IntelliJ IDEA,PyCharm,WebStorm,PhpStorm 优惠！

PureScript 0.6.8 发布，此版本更新内容如下：

重大改进

The Num type class has been refined to allow more interesting instances. The Semiring , ModuloSemiring , Ring and DivisionRing classes have been introduced. Most code should continue to compile, since Number was one of only a handful of instances, but library developers will need to break up their Num instances.

功能增强

@garyb has improved the readability of psc-docs output.

注意

全面废弃了 ErrorT ，使用 ExceptT 和 transformers 替换， mtl 依赖有点小改动

PureScript 是个小巧而强大的静态类型语言，可以编译成 JavaScript。purescript 主要是由 Haskell 和 PureScript 编写的。

PureScript 示例代码：

module Main where import Debug.Trace main = trace "Hello, World!"

编译成 JavaScript 代码：

var PS = PS || {}; PS.Main = (function () {  "use strict";  var Debug_Trace = PS.Debug_Trace;  var main = Debug_Trace.trace("Hello, World!");  return {   main: main  }; })();
