CHANGELOG.md: 记录项目的更新日志。LICENSE: 项目的许可证信息。README.md: 项目的介绍和使用说明。Setup.hs: 用于项目构建的设置文件。app/: 包含项目的启动文件。src/: 包含项目的主要源代码。test/: 包含项目的测试代码。extensible-effects.cabal: 项目的配置文件。

2. 项目的启动文件介绍

项目的启动文件位于 app/Main.hs，该文件通常包含程序的入口点，负责初始化和启动整个应用程序。




module Main where


 


import Control.Extensible.Effect


import Control.Extensible.Effect.Default


 


main :: IO ()


main = do


    putStrLn "Starting extensible-effects application..."


    -- 在这里添加你的初始化代码和主逻辑

3. 项目的配置文件介绍

项目的配置文件是 extensible-effects.cabal，该文件包含了项目的元数据、依赖关系、构建选项等信息。
