I have an interesting problem with my chess application. The application reads PGN files, and at any time while viewing a game from the file, the function below, when called, iterates over the chessboard, gets the square names for each piece, and then constructs a string containing the descriptio...

I attempted (incorrectly) to implement foldTree here.
Recently, I updated it per Petr's help:
treeFold :: (b -> [b] -> b) -> (a -> b) -> Tree a -> b
treeFold f g tree = f (g (rootLabel tree)) (map (treeFold f g) (subForest tree))
I implemented toList:
toList :: Tree a -> [a]

I've recently ported an old project and made it object-oriented. However, I've noticed that rubocop points out the following status: Assignment Branch Condition size for fetch_images is too high. [22.41/15]. Can I make this method be made more efficient, perhaps?
