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。

在日常层面上有巨大的区别——Vim(或任何vi变体)本质上是模态的(你进入命令模式，但你不能编辑)，而Emacs(以及大多数其他编辑器)不是。

当然，使用菜单之类的东西，你不需要在Vim中实际进入命令模式——首先。但即使使用Vim的一小部分力量，你也会。这是Vim/Emacs争论的核心。

就我个人而言，我还认为Emacs的可扩展性要强得多。你可以找到很多东西的Elisp包。

不过，我很好奇，为什么您考虑学习其中一种而不是更传统的IDE。你为什么要学这个?

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。

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.

击键执行::: Vi编辑将保留键入键的每个排列。这将在决策树中创建一个路径，该路径明确地标识任何命令，而Emacs命令是立即执行的键入键的组合，使用户可以选择是否使用命令。

内存使用和可定制性::: vi是一个更小更快的程序，自定义能力更有限，而Emacs启动时间更长，需要更多内存。然而，它是高度可定制的，并且包含大量的特性，因为它本质上是为文本编辑而设计的Lisp程序的执行环境。

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。
