Documentation
readFileLenient :: FilePath -> IO Text Source #
Read a UTF8 file, but don't crash on encoding errors.
dropBefore :: (a -> Bool) -> [a] -> [a] Source #
Drop until the element before the matching one. Return [] if the function never matches.
groupOnKey :: Ord key => (a -> key) -> [a] -> [(key, [a])] Source #
Group the unsorted list into (key x, xs)
where all xs
compare equal
after key
is applied to them. List is returned in sorted order.
