PureScript 静态类型语言
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 0.10.4 发布了,
主要更新内容:
新功能
Deriving Functor:
The Functor
type class can now be derived using the standard derive instance
syntax:
newtype F a = F { foo :: Array a, bar :: a } derive instance functorF :: Functor F
User-Defined Kinds:
Custom kinds can now be defined using the foreign import kind
syntax:
foreign import kind SymbolList
Custom kinds can be ascribed to types using foreign import data
declarations, as usual:
foreign import data Nil :: SymbolList foreign import data Cons :: Symbol -> SymbolList -> SymbolList
Source Maps in psc-bundle
:psc-bundle
will now generate source maps if the--source-maps
flag is used.
Solving CompareSymbol
and AppendSymbol
:Support for the new purescript-typelevel-prelude
library has been added to the compiler. CompareSymbol
and AppendSymbol
constraints will now be solved automatically for literal symbols.
New psc-package
