Emacs 29 is getting native Tree-Sitter support, and the buzz is hard to miss. Tree-Sitter maintains and provides a concrete parse tree of the buffer that you can query, but that’s as far as it goes. Acting on this information to provide context-aware navigation and editing tools is left to package authors, who have picked up this baton and started running with it! In the last few months we’ve had structural editing packages popping up all over the place.
