Welcome to WikEmacs - A Community Maintained Emacs Wiki


Useful resources for working with GNU Emacs. See also Emacs (Wikipedia).

WikEmacs (pronounced wikimacs) is intended as a next generation alternative to the traditional EmacsWiki.

Getting started with Emacs

Text editing in Emacs

Automation in Emacs

Configuring Emacs

Emacs and Desktop Integration

Typesetting, Document Markup and Document Creation in Emacs

Emacs as an IDE

Integrated Development Environment (IDE) for Emacs is called CEDET. See Gentle Introduction to CEDET.

For Literate Programming see Org Babel.

Programming and Scripting Languages

Markup Languages




  • Inferior Emacs Lisp Mode (IELM) for interacting with Emacs' own internal Lisp
  • mozrepl for interacting with an external web browser's internal JavaScript engine
  • SLIME for interacting with an external Common Lisp or Clojure instance

Version Control

  • dvc provides a standard interface between Emacs and distributed version control systems
  • vc provides a standard interface between Emacs and conventional version control systems

Within Emacs, ediff provides sophisticated diff and merge functions. Both vc and dvc integrate well with ediff.



Web browsing and web development

  • w3 : a pure-Emacs-Lisp text-mode web browser.
  • w3m-el : The text-mode w3m web browser hosted and enhanced within Emacs, with rudimentary inline image support but no JavaScript.
  • Launching and interacting with an external browser from emacs
  • Using emacs as a browser's external editor , either when entering text on web pages or when viewing a web page's source document or both.

Shells and terminal emulation

Within Emacs you can interact with various shells and other command-line/text-mode programs running as a sub-process within an Emacs terminal emulator:

eshell is a shell (not a terminal emulator, nor a process hosted in one) written in pure Emacs Lisp . It is very powerful, flexible and customizable, but poorly documented at time of writing.

Emacs itself is fully functional either in a terminal or a windowing system. Some keystrokes available under window systems may not work in a terminal and vice versa.
