Welcome to WikEmacs - A Community Maintained Emacs Wiki

About

Useful resources for working with GNU Emacs, the extensible, self-documenting text editor. See also Emacs (Wikipedia).

Emacs is free software (Wikipedia).

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

See WikEmacs:Guidelines for information on editing this wiki.

Getting started with Emacs

The latest stable release is Emacs-23.4. The next major release is Emacs-24.1 and is in Pretest stage.

Emacs is available on all popular Operating Systems including GNULinux, OSX and Windows. It supports variety of Programming languages.

Explore this Wiki based on your needs. Here are some starting points.

Whoever

Pages organized by your role in Emacs community. Whether you are a Emacs User, a Emacs Contributor or a Programmer. There is some thing just for you.

Workflow

Pages organized by your current workflow. Whether you want to write mails, browse the web, blog, read news feeds, author documents or for that matter get organized, there are few things just for you.

REPLs

Interactive command-line environments for Lisp. (Read-Eval-Print-Loop)

• 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

Emacs as an IDE

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

For Literate Programming see Org Babel.

Version Control

Emacs supports many Version Control systems out of the box and provides bindings and other shortcuts for a better workflow between Emacs and these systems.

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

Productivity

Communication

• Blogging
• Chat
• Email
• Feed reading
• Microblogging
• Usenet news

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:

• ansi-term
• shell
• term
• multi-term

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.

Accessibility

• Emacspeak for the visually challenged.

Security and cryptography
