In fact, if you run Emacs as a GUI application, you can probably get through the day without noticing you're in Emacs at all. You might think that a GUI renders Emacs less effective, as if "real text editors run in a terminal," but a GUI can make Emacs easier to learn because its GUI follows some typical conventions (a menu bar, adjustable widgets, mouse interaction, and so on). With a GUI, you can just launch Emacs from your application menu or a terminal. If you want to run GNU Emacs as a terminal application, you can launch it with the -nw option: $ emacs -nw This sometimes surprises people because Emacs is often pitted against Vi, which runs in a terminal (although gVim provides a GUI for a modern Vi implementation). GNU Emacs has at least two user interfaces: a graphical user interface (GUI) and a terminal user interface (TUI).

There are many examples of similarly useful applications-within-Emacs, including an email client, a PDF viewer, web browser, a shell, and a file manager. The wildly popular org-mode project is just one example: it's an Emacs plugin as well as a markdown syntax with mobile apps to interpret and extend its capabilities. But LISP dialects are powerful, and because Emacs is a LISP interpreter, you can build applications, whether they're Emacs plugins or prototypes of something you want to develop into a stand-alone project. As a consequence, Emacs is flexible as a text editor, customizable, and powerful.Įlisp (and Common Lisp, by extension) aren't necessarily the easiest languages to start out on, if you're used to Bash or Python or similar languages. In fact, you might think of it as a kind of precursor to Jupyter, combining a powerful programming language (called elisp, to be exact) with its own live environment. Playing Tetris in your text editor is probably not your primary goal on an everyday basis, but it goes to show that Emacs is, proudly, a programming platform. While it was frivolous, it was also an accurate indication of what Emacs is all about-the idea that users can reprogram their (virtual) worlds and do whatever they want with an application.
