PureScript v0.10.0 rc1 发布,静态类型语言
欢迎加入运维网交流群:263444886http://onexin.iyunv.com/source/plugin/onexin_bigdata/https://my.oschina.net/img/hot3.pngPureScript 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。
v0.10.0-rc.1 更新内容如下:
主要变化:
The new functional dependencies feature fixes type inference in some cases involving multi-parameter type classes. However, due to a bug in the compiler, some of those expressions were previously type checking where they should not have. As a result, it is necessary to add functional dependencies to some classes in order to make previous code type-check in some cases. Known examples are:
[*] MonadEff and MonadAff
[*] MonadState, MonadReader, and the rest of the MTL-style classes in transformers
These libraries will be updated before the final release of 0.10.*, but you might experience some issues in the meantime.
新功能:
Data.Newtype Deriving
It is now possible to derive the Newtype class for any data declaration which is a newtype, using the existing deriving instance syntax:
newtype Test = Test String
derive instance newtypeTest :: Newtype Test _ Note that the second type argument should be specified as a wildcard, and will be inferred.
