concatTopPadded :: [String] -> String Source

Join multi-line strings as side-by-side rectangular strings of the same height, top-padded.

concatBottomPadded :: [String] -> String Source

Join multi-line strings as side-by-side rectangular strings of the same height, bottom-padded.

padtop :: Int -> String -> String Source

Convert a multi-line string to a rectangular string top-padded to the specified height.

padbottom :: Int -> String -> String Source

Convert a multi-line string to a rectangular string bottom-padded to the specified height.

padleft :: Int -> String -> String Source

Convert a multi-line string to a rectangular string left-padded to the specified width.

padright :: Int -> String -> String Source

Convert a multi-line string to a rectangular string right-padded to the specified width.

cliptopleft :: Int -> Int -> String -> String Source

Clip a multi-line string to the specified width and height from the top left.

fitto :: Int -> Int -> String -> String Source

Clip and pad a multi-line string to fill the specified width and height.

difforzero :: (Num a, Ord a) => a -> a -> a Source

splitAtElement :: Eq a => a -> [a] -> [[a]] Source

leaves :: Tree a -> [a] Source

List just the leaf nodes of a tree

subtreeat :: Eq a => a -> Tree a -> Maybe (Tree a) Source

get the sub-tree rooted at the first (left-most, depth-first) occurrence of the specified node value

subtreeinforest :: Eq a => a -> [Tree a] -> Maybe (Tree a) Source

get the sub-tree for the specified node value in the first tree in forest in which it occurs.

treeprune :: Int -> Tree a -> Tree a Source

remove all nodes past a certain depth

strace :: Show a => a -> a Source

trace (print on stdout at runtime) a showable expression (for easily tracing in the middle of a complex expression)

ltrace :: Show a => String -> a -> a Source

labelled trace - like strace, with a newline and a label prepended

parsewith :: Parser a -> String -> Either ParseError a Source

trace an expression using a custom show function
