haskell - 将 ghc-options 传递给 Stack 脚本解释器

Question

我正在使用堆栈解释器功能并拥有如下代码:

#!/usr/bin/env stack 
-- stack script --resolver lts-12.7 --package yesod 

main = print "hello"

我想将 ghc-options 选项传递给堆栈解释器。这可能吗？

Answer 1

最新版本的 Stack 直接支持 ghc-options:

#!/usr/bin/env stack 
-- stack script --resolver lts-12.7 --package yesod --ghc-options -Wall

main = print "hello"

执行时:

$ stack jest.hs

  | ^^^^
"hello"
