There's a method to this apparent madness, though, because Emacs is built to be flexible in how it's used. Learning Emacs can be difficult because it uses keyboard combinations fundamentally different from the way modern computers do.
FeaturesĬomputer enthusiasts don't love Emacs just because it happens to be old and free. Today, although there are other emacsen (the plural of "emacs" is "emacsen"), the most common version of Emacs is GNU Emacs. Stallman started the GNU project, Emacs became one of its most successful applications. In 1983, Richard Stallman released a bundle of his macros under the name editing macros, or emacs for short. Editing big documents this way can get tedious, so people started developing macros to perform common, related tasks. Instead, a text editor was a command that could generate words and dump them into a file, or find and replace words in a file, or remove lines from a file, and so on. A text editor is essentially a word processor without any of the decoration like fancy fonts and page styles or page layouts.Įarly text editors were so rudimentary that they couldn't even open an entire text document at once. In the early days of computing, word processors didn't exist at all, and text editors barely did. As time has shown, however, once you learn the basics, you have a powerful, efficient, and extremely hackable editor for life. Users love Emacs because it features efficient commands for common but complex actions and for the plugins and configuration hacks that have developed around it for nearly 40 years.īecause it's an old editor that was developed well before modern computer conventions and terminology existed (for instance, you "visit" instead of "opening" a file, and you "write" instead of "save," and so on), Emacs is often viewed as complex and even mysterious.
