Advanced features in Emacs and Vi
Emacs and Vi are two of the most popular text editors used by programmers, developers, and writers worldwide. Both editors have been around for decades, and each one has its loyal fan base. While they may look similar on the surface, Emacs and Vi have many differences. Let’s take a closer look at some of the advanced features of these two editors.
Extensibility and Customization
Emacs is known for its extensibility. It is highly customizable, and users can add or modify features to suit their needs. Emacs has a built-in Lisp interpreter that enables users to write Emacs Lisp code to extend the editor’s functionality. Users can write custom commands, scripts, macros, and plugins to automate tasks, integrate with external tools, and enhance the editing experience.
Vi has a less flexible and customizable approach compared to Emacs. However, its versatility lies in its ability to be used in combination with other Unix-based tools, including shell commands, sed, and awk. Users can write scripts to automate tasks by piping text through vi and other commands.
Command and Editing Modes
- Emacs has two primary modes: Command mode and Editing mode. In Command mode, users can navigate through the document, scroll, search, and execute commands. Editing mode is where users can insert and edit text using keystrokes and combinations.
- Vi has two modes; Insert mode and Command mode. Insert mode is where users can type text directly into the document. In Command mode, users can navigate, search, delete, and copy text. Vi’s Command mode is often considered faster and more efficient than Emacs’ Command mode.
Language Support
Emacs has a wide range of language support. It has built-in modes for syntax highlighting, indentation, and code completion for most programming languages. Some modes are useful for specific purposes only. For example, Org mode is a plain-text markup language for notes, outlines, and To-Do lists.
Vi has somewhat limited language support compared to Emacs. By default, it comes with syntax highlighting support, but users need to install plugins to get indentation and code completion support. Users can install plugins for most programming languages.
Multiple Buffers and Split Windows
Emacs has a powerful window management system, allowing users to split the editing window into multiple buffers. They can also split the window into multiple frames, each containing its buffers. It is useful for comparing files, viewing two parts of the same file simultaneously, or working on multiple files simultaneously.
| Command | Description |
|---|---|
| Ctrl + x, 2 | Splits the editing window into two vertical windows |
| Ctrl + x, 3 | Splits the editing window into two horizontal windows |
| Ctrl + x, o | Navigates to the next window |
Vi also supports multiple buffers and split windows, but it doesn’t have Emacs’ flexibility. Users can split the editing window horizontally or vertically, navigate between buffers, and split the buffer into multiple windows using Vim plugins.
When deciding between Emacs and Vi, it comes down to personal preference. Both editors have their strengths and weaknesses, and it’s up to users to decide which editor suits them best. However, mastering both editors is an excellent skill to have as they’re ubiquitous in the programming world, and having familiarity with both can make users more productive in their work.

| Has a flexible and powerful search and replace functionality that supports regular expressions and multi-file search. | Uses a modal approach that allows users to perform commands quickly without moving their hands from the home row. |
| Has a built-in file manager that allows users to navigate and manage files without leaving the editor. | Offers an extensive set of built-in commands that allow users to perform advanced text manipulation tasks. |
Community Support
Both Emacs and Vi have active communities that provide support and plugins for their users.
Emacs has a larger and more diverse community that offers a wide range of plugins for different programming languages and workflows. Emacs also has a built-in package manager that makes it easy to install and manage plugins.
Vi has a more focused community that mainly consists of programmers and system administrators who use it for their daily tasks. Vim has a built-in plugin manager that allows users to install and manage plugins easily.
In conclusion, choosing between Emacs and Vi depends on your preferences, needs, and workflow. Both editors are powerful and customizable, but their approaches to editing, customizability, and learning curves are significantly different. It’s recommended that you try both editors and see which one suits you better.
Common errors and solutions in Emacs and Vi
Emacs and Vi are two of the most popular text editors that have been around for decades. While both editors have their unique features, they also have their fair share of errors and issues that users may encounter. Here are some common errors and solutions in Emacs and Vi:
- Forgotten commands: It’s easy to forget some of the commands, especially if you don’t use them often. In Emacs, you can use the “C-h” key followed by any letter to get a list of possible commands starting with that letter. In Vi, you can use the “help” command to get a list of commands with their descriptions.
- Accidental deletions: Accidentally deleting text or code is a common mistake that happens to the best of us. In Emacs, you can use the “C-g” key to cancel any current command and undo any accidental deletions. In Vi, use the “u” or “Ctrl-r” keys to undo or redo the last action.
- Undo levels: Sometimes, you may find that you need to undo several steps instead of just the last one. In Emacs, you can use the “C-x u” keys to view a list of undo levels and select the one you want to undo to. In Vi, you can use the “u” key with a number to undo multiple steps. For example, “3u” will undo the last three steps.
Here is a table that shows some of the most common errors and their solutions:
| Error | Emacs solution | Vi solution |
|---|---|---|
| Accidentally pasted text | Use “C-_C-x u” to undo and discard the changes | Use “u” or “Ctrl-r” to undo or redo the last action |
| Lost cursor position | Use “C-x C-x” to go back to the previous cursor position. Use “M-g g” to go to a specific line number | Use “Ctrl-o” to go back to the previous cursor position. Use “:%n” to go to a specific line number |
| Can’t exit the editor | Use “C-x C-c” to exit Emacs. Use “C-g” to cancel any current command | Use “:q” to exit Vi. Use “:q!” to force exit without saving changes |
Knowing how to solve some of the common errors and issues in Emacs and Vi can save you time and frustration. With experience, you’ll become more proficient in using these text editors and avoid these errors altogether.
