ghc-pkg和cabal之间的关系是什么？ [英] What is the relationship between ghc-pkg and cabal?

问题描述

关于如何在Haskell中创建，安装和使用包， ghc-pkg 和 cabal ？

他们的角色是什么 - 你们什么时候使用一种，哪种比较好，或者同时使用两种？ p

工具，或简单的工具，做不同的工作？

解决方案

以图形方式，依赖项是：

  GHC包可以使用
 | 
使用ghc-pkg注册
 |进行注册
并且（几乎总是）用Cabal 
 |构建
通过cabal-install 
 |解决了构建依赖关系
来自Hackage。 
  

With respect to how packages are created, installed and used in Haskell, what is the relationship between ghc-pkg and cabal?

What are their roles - when would you use one, over the other, or use both?

Are they complementary tools, competitive tools, or simply tools that do different jobs?

解决方案

Graphically, the dependencies are:

Packages GHC can use
    | 
Are registered with "ghc-pkg register"
    |
And (almost always) built with Cabal
    |
With build dependencies resolved by cabal-install
    |
From Hackage.
