But the `translate` function is only used on Windows No:
{{{ translate :: String -> String #if mingw32_HOST_OS translate xs = '"' : snd (foldr escape (True,"\"") xs) where escape '"' (_, str) = (True, '\\' : '"' : str) escape '\\' (True, str) = (True, '\\' : '\\' : str) escape '\\' (False, str) = (False, '\\' : str) escape c (_, str) = (False, c : str) -- See long comment above for what this function is trying to do. -- -- The Bool passed back along the string is True iff the -- rest of the string is a sequence of backslashes followed by -- a double quote. #else translate "" = "''" translate str -- goodChar is a pessimistic predicate, such that if an argument is -- non-empty and only contains goodChars, then there is no need to -- do any quoting or escaping | all goodChar str = str | otherwise = '\'' : foldr escape "'" str where escape '\'' = showString "'\\''" escape c = showChar c goodChar c = isAlphaNum c || c `elem` "-_.,/" #endif }}}
is your bug report about Windows No, it's about Linux (does Windows even have awk?)
