I'm a bit surprised helix editor is not mentioned. It is based on tree-sitter grammars and allows for stuff like select-around-function or select-around-argument, to use grammar in the code navigation. Pretty wild and useful.
Is it built into the editor itself? In neovim you need to install a separate plugin "nvim-treesitter-textobjects" to get that.
Yes. Highlighting, these selection actions and symbol detection all work with tree-sitter grammars. The whole premise of the editor is a modern-modal-editing with tree-sitter grammars.
