Changelog
0.12.0 (2020-10-23)
Tree.iterate no longer allows returning from inside the iteration (use cursors directly for that kind of use cases).
Subtree has been renamed to SyntaxNode and narrowed in scope a little.
The top, skipped, and error node props no longer exist.
The package now offers a TreeCursor abstraction, which can be used for both regular iteration and for custom traversal of a tree.
SyntaxNode instances have nextSibling/prevSibling getters that allow more direct navigation through the tree.
Node types now expose isTop, isSkipped, isError, and isRepeated properties that indicate special status.
Adds NodeProp.group to assign group names to node types.
Syntax nodes now have helper functions getChild and getChildren to retrieve direct child nodes by type or group.
NodeType.match (and thus NodeProp.add) now allows types to be targeted by group name.
Node types have a new is method for checking whether their name or one of their groups matches a given string.
