Hoogle has plenty of bugs, consider them features until they are fixed :) To report a bug either email me or just add it to this list.
Bad Searches
- (a -> b) -> ([a] -> [b]) -- should find map
- @hoogle Data.IntMap.IntMap a -> [a] -- badly kills the module names
- @hoogle -- , gives copyright message (consequence of argument parsing in command line)
- Either, should find Left and Right
- @hoogle (\=), bracket does not parse
Higher Kinds
The following searches are all wrong because Hoogle doesn't understand higher kinds, i.e. Monad's.
- Functor f => (a -> b) -> f a -> f b -- should find fmap
- Monad m => [m a] -> m [a] -- should find sequence
- (Monad m) => m (m a) -> m a -- should find join
Bad Ordering
- Ptr a -> IO a [peek should be first]
- Foreign.Storable.peekByteOff :: Storable a => Ptr b -> Int -> IO a
- Foreign.Storable.peek :: Storable a => Ptr a -> IO a
Other Issues
While trying to run hihoo.pl on the NewBinary library, I received the following problems
- hihoo is currently unmaintained, I recommend hadhtml. If someone is able to fix it up... --Neil Mitchell 19:22, 13 February 2006 (UTC)
