如何在Haskell中读取内置函数的实现代码/源代码? [英] How to read the implementation code/source code for inbuilt functions in Haskell?

问题描述

例如，如果我想阅读Prelude中默认的 curry 函数的源代码，该在哪里引用?有没有办法阅读它的实现?我试图在Hoogle中搜索它，但是它没有给出确切的实现，只是输入和输出类型.我在堆栈上使用GHCI来运行haskell.-

接着，您将进入 curry 的源代码:

 -|"curry"将未咖喱函数转换为咖喱函数.咖喱::(((a，b)-> c)->a->b->C咖喱f x y = f(x，y) 

For instance if I would like to read the source code for the default curry function in Prelude, where do I refer? Is there a way to read it's implementation? I tried to search it in Hoogle, but it doesn't give the exact implementation, just the input and output types. I am using GHCI on stack to run haskell.-

Hoogle curry

解决方案

Like @Lee mentioned in the comments, there is a link for source for many of the functions on hackage.

Following this will take you to the source code for curry:

-- | 'curry' converts an uncurried function to a curried function.
curry                   :: ((a, b) -> c) -> a -> b -> c
curry f x y             =  f (x, y)
