Emacs: 智能感知和操作光标处的语法对象

我在 2008 年开发了 thing-edit.el , 虽然这个插件平常没啥存在感, 但是几乎是天天都在用的插件.

thing-edit.el 简单来说, 就是不用移动光标, 会自动把光标处的各种语法对象 (表达式、邮件地址、文件名、URL、单词、符号、函数定义、列表、句子、空格、段落、行、注释、括号内容等)进行识别并操作, 比如复制, 剪切或者粘贴 kill-ring 内容.

thing-edit.el 相对于其他复制插件的优势在于你完全不用移动光标即可智能的感知语法对象并进行快速的操作. 等操作完成以后可以继续从当前的位置继续编程.

thing-edito.el 本来放到我自己的 插件目录中

如果各位喜欢, 觉得有新的功能需要扩展, 我会把我自己的插件从 lazycat-emacs 中抽取出来, 单独成一个 git 仓库方便大家发送PR.

谢谢 谢鹏 同学编写的 thing-replace-* 函数, 非常的好用.
