如何使用Stack在另一个项目中导入个人库? [英] How to use import a personal library in another project with Stack?

问题描述

所以我有一个个人堆栈库，我们称它为Foo.在Foo中，我有一个名为FooModule.hs的FooModule模块文件. 我还有一个名为Bar的堆栈项目.如何将FooModule.hs模块导入项目Bar?

So I have a personal stack library, let's call it Foo. In Foo, I have a FooModule module file named FooModule.hs. I have another stack project called Bar. How do I import the FooModule.hs module to project Bar?

推荐答案

我一直都这样做.在您的stack.yaml文件中，将路径添加到Foo包中:

I do this all the time. In your stack.yaml file, add the path to the Foo package:

-- stack.yaml
packages:
- '.'
- lib/foo

然后在您的Bar.cabal文件中，您说您的构建依赖于Foo

And then in your Bar.cabal file you say that your build depends on Foo

-- project.cabal
...
build-depends:       base >= 4.7 && < 5
                   , foo
