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

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)

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

parse :: P TT (Tree TT)

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

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

tokenToStroke :: TT -> Stroke

modStroke :: StyleName -> Stroke -> Stroke

tokenToAnnot :: TT -> Maybe (Span String)

errTok :: Parser (Tok t) (Tok Token)

Create a special error token. (e.g. fill in where there is no correct token to parse) Note that the position of the token has to be correct for correct computation of node spans.
