Emacs和Vim之间有什么实际的、客观的区别?例如,使用一个可以做而另一个不行(或者使用一个比另一个更容易做)?为了选择一门课程,我应该知道些什么?

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.

(以下文字是我的观点,不应被视为事实或侮辱)

With Emacs you are expected to have it open 24/7 and live inside the program, almost everything you do can be done from there. You write your own extensions, use it for note-taking, organization, games, programming, shell access, file access, listening to music, web browsing. It takes weeks and weeks till you will be happy with it and then you will learn new stuff all the time. You will be annoyed when you don't have access to it and constantly change your config. You won't be able to use other peoples emacs versions easily and it won't just be installed. It uses Lisp, which is great. You can make it into anything you want it to be. (anything, at all)

对于Vim,它几乎总是预先安装的。这是太快了。你打开一个文件做一个快速编辑,然后退出。如果您在其他人的机器上,则可以使用基本设置。它的可编辑性不是很好,但它仍然比大多数文本编辑器好得多。它能识别出你大部分时间是在阅读/编辑而不是打字,并使这部分工作更快。你的小指没有emacs症状。这并没有那么令人愤怒。这样更容易学。

即使我每天都在使用Emacs(而且喜欢它),除非你打算在你选择的程序上花费大量时间,否则我会选择vim

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

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。

如果您经常从一个站点移动到另一个站点,或者您的工作涉及到登录到生产系统,那么vim就是合适的选择。

默认情况下,所有*nix机器都会安装vi。

大多数sysdamins更喜欢ksh作为默认shell。KSH使用vi(或emacs)命令击键来搜索历史记录并编辑命令行。

如果你不太了解vi,当你登录到一个标准配置的unix机器上时,你就会受到严重的限制。

仅仅因为这个原因,我推荐vim作为你日常的编辑器。我曾经见过emacs爱好者试图在一个基本的unix服务器上修改配置文件。
