我正在使用堆栈解释器功能,并具有如下代码:

#!/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。有可能吗?

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"
