https://github.com/manateelazycat/grammatical-edit 是基于 tree-sitter 的结构化编辑插件, 这个项目的目标是实现 ParEdit、thing-edit、textobj 这三类插件的功能合集。
最主要的优点是基于 tree-sitter 的 AST 而不是正则来实现语法对象编辑，只要 tree-sitter 支持的编程语言，都可以进行结构性编辑，不需要像 smartparens 或者 awesome-pair.el 针对一些偏门语言增加 workaround, 甚至是明天才发布的新编程语言都可以支持。
安装方法
- 先安装 tree-sitter: Installation :: Emacs Tree-sitter
- 下载 grammatical-edit 后在配置文件中加入
(require 'grammatical-edit)

添加 tree-sitter 对 elisp 的支持
1. git clone https://github.com/Wilfred/tree-sitter-elisp
2. gcc ./src/parser.c -fPIC -I./ --shared -o elisp.so
3. cp ./elisp.so ~/.tree-sitter-langs/bin
(tree-sitter-load 'elisp "elisp")
(add-to-list 'tree-sitter-major-mode-language-alist '(emacs-lisp-mode . elisp))
添加Vue对tree-sitter支持
1. git clone https://github.com/ikatyang/tree-sitter-vue.git
2. gcc ./src/parser.c ./src/scanner.cc -fPIC -I./ --shared -o vue.so
3. cp ./vue.so ~/.tree-sitter-langs/bin (~/.tree-sitter-langs/bin is path of your tree-sitter-langs repo)
(tree-sitter-load 'vue "vue")
(add-to-list 'tree-sitter-major-mode-language-alist '(web-mode . vue))
备注
grammatical-edit的代码 fork 于 awesome-pair.el ， 仍然有一部分代码需要从原来正则匹配转换成 AST 逻辑，欢迎大家试用反馈。
