I have the following code:
foo :: Int -> [String] -> [(FilePath, Integer)] -> IO Int
foo _ [] _ = return 4
foo _ _ [] = return 5
foo n nameREs pretendentFilesWithSizes = do
result <- (bar n (head nameREs) pretendentFilesWithSizes)
if result == 0
then return 0 -- <========================================== here is the error
else foo n (tail nameREs) pretendentFilesWithSizes
I get an error on the line with the comment above, the error is:
aaa.hs:56:2:
parse error (possibly incorrect indentation)
I'm working with emacs, there's no spaces, and i do not understand what did i do wrong.
