Documentation

doCpp :: Logger -> TmpFs -> DynFlags -> UnitEnv -> CppOpts -> FilePath -> FilePath -> IO () Source #

Run either the Haskell preprocessor, JavaScript preprocessor or the C preprocessor, as per the CppOpts passed. See Note [Preprocessing invocations].

UnitEnv is needed to compute MIN_VERSION macros

If you change the macros defined by this function make sure to update the user guide.
