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.

Vim:

作为一个简单的编辑器更好(简单任务所需的键更少) 更活跃的脚本社区-内部语言:vimscript 一个集中的脚本、插件、配色方案…… 在python、ruby中也可扩展 可移植(emacs在这方面存在一些问题)

Emacs:

non modal by default (most of today's editors have taken this approach). Though there is evil-mode which emulates vim behavior. more powerful language for extending it (elisp is a full blown language, and in emacs you can practically redefine everything; while in vim you cannot redefine build in functions of the editor. On the downside, vimscript is relatively similar to today's dynamic languages while elisp doesn't resemble pretty much anything) more extendible excellent support for GNU tools (the bunch of them)

就我个人而言，我更喜欢vim——它很小，做了它应该做的事情，当我想要一个完整的IDE时，我打开它VS. Emacs的方法是一个编辑器，它想成为一个IDE(或者我应该说，一个操作系统)，但并不完全，在我看来，过时了。以前有电子邮件客户端、ftp客户端、俄罗斯方块……一个包(emacs)中的东西是有意义的……如今，它不再是了。

然而，这两者都是程序员和超级用户社区用户之间的宗教讨论话题，在这方面，如果接触(在同一句话/问题中)，两者都很适合开始激烈的战争。

对我来说，emacs的优点是，

tramp模式允许您通过ssh编辑远程文件。就像本地文件一样。 Tramp-mode + dired =全功能SFTP客户端 支持您需要的所有语言。 内置的终端模拟器(术语模式)，所以我可以继续编码，而无需在应用程序之间切换。 可扩展性任何你不喜欢的东西都可以用lisp来改变。

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。

我是Emacs的粉丝，但我鼓励其他开发人员学习VI，因为:

你可以使用VI编辑emacs的makefile文件。 VI包含ed命令，每个UNIX用户都应该知道ed和sed。

我注意到一些关于VIM启动速度比emacs快的评论。如果您真的关心这个问题，请在服务器模式下运行emacs，并将“emacs”别名为“emacsclient”。客户端速度非常快，因为它所做的一切都是轻拍服务器的肩膀，告诉它你想编辑哪个文件。在MacOSX上，emacsclient只有33K，而emacs是287M。

我不确定这些在现代硬件上是否有必要。在我的MacBook Pro (2013 Retina)上，当我从shell运行emacs时，它几乎是立即加载的。我丝毫没有察觉到停顿。当我运行Emacs时。app (GUI版本)可能需要3秒。

我听到的大多数关于emacs的抱怨似乎都来自那些对emacs不了解的人。我从1982年就开始使用vi和emacs了，我清楚地记得，在我早期的UNIX机器中，emacs加载速度比vi慢得多，并且占用了大部分物理内存，但现在已经不再是这样了，至少15-20年都没有了。

我承认的一个抱怨是“emacs小指”。在我年轻的时候，这从来没有困扰过我。现在我已经58岁了，我的小手指确实因为反复使用Control键进行emacs和弦而有点酸痛。在MacBook Pro的键盘上尤其如此，“控制”键向右移动了一个位置，为“fn”键腾出空间。当Control是左下角的键时，它几乎没有那么烦人。

我从vi开始，到emacs，然后到vim。我一直想试试Emacs，看看在过去五年中发生了什么变化。(说到IDE，我已经使用eclipse有一段时间了，但我更喜欢我的终端窗口连接我的mac和我(丈夫的)linux盒子)。

剪切粘贴的事最近一直困扰着我。在Vim中剪切和粘贴比在Emacs和IIRC中需要更多的步骤。从浏览器粘贴到终端窗口很烦人，除非你做了一些我不喜欢做的奇特的事情，所以我忍受了奇怪的缩进。我认为，在emacs中编辑多个文件更容易。如果两个文件都在屏幕上，至少可以从一个文件跳转到下一个文件。

我没有使用vi或emacs的花哨特性，因为我只是想开始编码的工作。我所需要的是漂亮的颜色和适当的制表符到空格的转换(对python尤其重要)。

我认为这完全取决于你是想使用:wq还是Ctrl-x Ctrl-s (IIRC)来保存文件，如果你不关心花哨的东西。

@mgb是正确的。一两个月前，我曾在Debian发行版中使用最低限度的linux来修复一些东西。Vi是唯一可用的编辑器。
