GNU Emacs is an extensible, customizable, free/libre text editor. At its
core is an interpreter for Emacs Lisp, a dialect of the Lisp programming
language with extensions to support text editing.
The features of GNU Emacs include:
- content-aware editing modes, including syntax coloring, for many file
types
- complete built-in documentation, including a tutorial for new users
- full Unicode support for nearly all human scripts
- powerful customizability, using Emacs Lisp code or a graphical
interface
- a vast ecosystem of functionality beyond text editing, including a
project planner, mail and news reader, debugger interface, calendar,
even a psychotherapist, and more
- a packaging system for downloading and installing extensions.
