Emacs实际上更像是一个无所不能的程序，而vi(m)实际上只是一个编辑器。如果您正在编辑文本，它们都很好，但我更喜欢emacs，因为我必须将一个移出主行才能移动，并在命令模式中不断键入错误的内容。如果您没有这个问题，vi(m)可能是您的编辑器。

Vim was always faster to start up than Emacs. I'm saying that on any machine, out-of-the-box installs of Vim will start up faster than out-of-the-box installs of Emacs. And I tend to think that after a moderate amount of customisation of either one, Vim will still start up faster than Emacs. After that, the other practical difference was Emacs' modes. They make your life tremendously easier when editing XML, C/C++/Java/whatever, LaTeX, and most popular languages you can think of. They make you want to keep the editor open for long sessions and work.

总而言之，我会说Vim让您使用它来完成简短、快速的编辑任务;而Emacs则鼓励您投入长时间的会话。

Emacs的好处

Emacs has both non-modal interface (by default) and modal one (e.g. it can emulate vim and vi through Evil, Viper, or Vimpulse). One of the most ported computer programs. It runs in text mode and under graphical user interfaces on a wide variety of operating systems, including most Unix-like systems (Linux, the various BSDs, Solaris, AIX, IRIX, macOSetc.), MS-DOS, Microsoft Windows, AmigaOS, and OpenVMS. Unix systems, both free and proprietary, frequently provide Emacs bundled with the operating system. Emacs server architecture allows multiple clients to attach to the same Emacs instance and share the buffer list, kill ring, undo history and other state. Pervasive online help system with keybindings, functions and commands documented on the fly. Extensible and customizable Lisp programming language variant (Emacs Lisp), with features that include: A powerful and extensible file manager (dired), integrated debugger, and a large set of development and other tools. Having every command be an Emacs Lisp function enables commands to DWIM (Do What I Mean) by programmatically responding to past actions and document state. For example, a switch-or-split-window command could switch to another window if one exists, or create one if needed. This cuts down on the number of keystrokes and commands a user must remember. "An OS inside an OS". Emacs Lisp enables Emacs to be programmed far beyond editing features. Even a base install contains several dozen applications, including two web browsers, news readers, several mail agents, four IRC clients, a version of ELIZA, and a variety of games. All of these applications are available anywhere Emacs runs, with the same user interface and functionality. Starting with version 24, Emacs includes a package manager, making it easy to install additional applications including alternate web browsers, EMMS (Emacs Multimedia System), and more. Also available are numerous packages for programming, including some targeted at specific language/library combinations or coding styles.

vi类编辑器的好处

Edit commands are composable Vi has a modal interface (which Emacs can emulate) Historically, vi loads faster than Emacs. While deeply associated with UNIX tradition, it runs on all systems that can implement the standard C library, including UNIX, Linux, AmigaOS, DOS, Windows, Mac, BeOS, OpenVMS, IRIX, AIX, HP-UX, BSD and POSIX-compliant systems. Extensible and customizable through Vim script or APIs for interpreted languages such as Python, Ruby, Perl, and Lua Ubiquitous. Essentially all Unix and Unix-like systems come with vi (or a variant) built-in. Vi (and ex, but not vim) is specified in the POSIX standard. System rescue environments, embedded systems (notably those with busybox) and other constrained environments often include vi, but not emacs.

我是一个不折不扣的Emacs迷，但我早在认识Emacs之前就认识VI了。也就是说，我让我所有的人学习VI，因为它总是可用的，在任何地方。选哪一个都不会错。

Vim是一个方便的编辑器，你只需输入Vim的文件名来打开文件，编辑，保存和关闭。

Emacs是一个伪装成编辑器的“操作系统”，你可以评估代码来改变它的行为，并按你的喜好扩展它。在emacs上接收/发送电子邮件的模式类似于操作系统上的电子邮件软件。

当进行简单的编辑时，例如，修改配置文件，我使用vim。

否则，我永远不会离开emacs。

VI总是可用的，并且将在最残缺的、单用户模式、坏的图形、没有键图、慢的链接机器上运行——因此，仅仅为了系统管理任务，了解如何在它中编辑简单的文件是值得的。

Emacs是一个编辑器中的完整用户界面。其思想是在启动机器时启动Emacs，并且永远不要离开它。可能会有数千个会话。

与使用GUI编辑器/IDE和使用python/awk/等来完成额外任务相比，学习Emacs的功能是否值得，取决于你自己。
