如何在堆栈中创建项目模板?

haskell-stack haskell

softshipper · 技术社区 · 5 年前

我将创建几个项目。这些项目将使用相同的依赖项,例如:

dependencies:
- base >= 4.7 && < 5
- classy-prelude

default-extesion:
- NoImplicitPrelude
- OverloadedStrings

问题是,如何在堆栈中创建包含默认值的模板 dependencies ,就像上面列出的。

您可以更改Haskell模板,例如 simple template on GitHub . 您可以在本地保存修改后的文件,例如 ~/simple-classy.hsfiles ,然后使用以下内容构建新项目:

stack new name ~/simple-classy.hsfiles

例如,这里有一个稍微修改过的版本 simply.hsfiles . 当然,您可以对模板进行更重要的更改:

{-# START_FILE package.yaml #-}
name:    {{name}}
version: "0.0.0"

dependencies:
  - base >= 4.7 && < 5
  - classy-prelude

default-extension:
  - NoImplicitPrelude
  - OverloadedStrings

{-# START_FILE {{name}}.cabal #-}
name:                {{name}}
version:             0.1.0.0
