accessors :: Lookup a => a -> AccessorTree a Source

flatten :: AccessorTree a -> [(String, Getter a, Setter a)] Source

showTree :: AccessorTree a -> (Getter a -> String) -> String Source

Show a tree of values

showFlat :: forall a. AccessorTree a -> Bool -> (Getter a -> String) -> String Source

Show a list of values . True --> align the colums, False --> total mayhem
