Fields
| |
rawCppArgs :: [String] -> FilePath -> CppArgs #
use the given preprocessor arguments without analyzing them
addCppOption :: CppArgs -> CppOption -> CppArgs #
add a typed option to the given preprocessor arguments
addExtraOption :: CppArgs -> String -> CppArgs #
add a string option to the given preprocessor arguments
runPreprocessor :: Preprocessor cpp => cpp -> CppArgs -> IO (Either ExitCode InputStream) #
run the preprocessor and return an InputStream if preprocesssing succeeded
isPreprocessed :: FilePath -> Bool #
guess whether a file is preprocessed (file end with .i)
