Documentation
sepBy :: Alternative f => f a > f v > f [a] Source #
sepBy1 :: Alternative f => f a > f v > f [a] Source #
getFirstElement :: Foldable t => t a > Maybe a Source #
Return the 1st token of a subtree.
getLastElement :: Foldable t => t a > Maybe a Source #
Return the last token of a subtree.
getLastPath :: IsTree tree => [tree (Tok t)] > Point > Maybe [tree (Tok t)] Source #
Search the given list, and return the last tree before the given point; with path to the root. (Root is at the start of the path)
getAllSubTrees :: IsTree tree => tree t > [tree t] Source #
Return all subtrees in a tree, in preorder.
tokenBasedAnnots :: Foldable t1 => (a1 > Maybe a) > t1 a1 > t > [a] Source #
tokenBasedStrokes :: Foldable t3 => (a > b) > t3 a > t > t2 > t1 > [b] Source #
fromLeafToLeafAfter :: IsTree tree => Point > Node (tree (Tok a)) > Node (tree (Tok a)) Source #
Search the tree in preorder starting at a given node, until
finding a leaf which is at or after the given point. An effort is
also made to return a leaf as close as possible to p
.
