首先，Vi(原始实现)今天不使用。你说的是一些Vim推导。

要扩展Vim功能，必须重新编译Vim, Emacs则不必。

Emacs在self中有Vim (viper模式)。

Emacs通常需要手动安装，Vim通常预安装在所有Unix之类的操作系统上(但如果你有ssh访问主机的tramp模式win Vim:)。

如果你尝试Vim，那么你讨厌Emacs，所以先从Emacs开始。

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。

Emacs具有Viper模式，因此在某种意义上，它提供了一个超特性集(除了那些在使用Viper和Vimpulse的Emacs中缺少哪些Vim特性?)

vi(和VIM IIRC)的重量较轻(它可以就地编辑文件)，但提供的功能较少(子进程通信、扩展语言)。

对于我来说，选择使用emacs而不是vim的最大区别是emacs内置的gdb支持。Vim的默认发行版中并没有包含这个功能，而且用于集成gdb和Vim的项目几乎不可能使用MacVim

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.

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。
