我正在使用堆栈解释器功能并具有这样的代码:
#!/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。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"
在执行时:
$ stack jest.hs
/home/sibi/github/subsite/jest.hs:4:1: warning: [-Wmissing-signatures]
Top-level binding with no type signature: main :: IO ()

"hello"
