getIndentingSubtree :: Tree TT -> Point -> Int -> Maybe (Tree TT) Source

Search the given list, and return the 1st tree after the given point on the given line. This is the tree that will be moved if something is inserted at the point. Precondition: point is in the given line.

getSubtreeSpan :: Tree TT -> (Point, Int) Source

Given a tree, return (first offset, number of lines).

parse :: P TT (Tree TT) Source

parse' :: (TT -> Token) -> (Token -> TT) -> P TT [Tree TT] Source

getStrokes :: Point -> Point -> Point -> Tree TT -> [Stroke] Source
