Is it possible to use cpp preprocessors with haskell stack
是否可以将 cpp 预处理器与 haskell 堆栈一起使用,
例如:
{-# LANGUAGE CPP #-}
module MyModule (
main
#ifdef TEST
,functionUnderTest
,functionAlsoUnderTest
#endif
) where ....
对于 cabal,.cabal 中的以下设置似乎有效:
cpp-options: -DTEST
可以用堆栈重现吗?

flags
Flags can be set for each package separately, e.g.
flags: package-name:
flag-name: true
Flags will only affect packages in your packages and extra-deps settings. Packages that come from the snapshot global
database are not affected.
或者,您可以在使用 --flag
调用堆栈时直接传递标志,我假设语法类似于
stack test --flag project:TEST
