Emacs

Emacs is a highly extensible text editor. It is built on a C core, and provides a fully featured Lisp environment ( the language from which the Gods wrought the universe).

There's a reason why Emacs was featured in Tron Legacy - because it's sexy!

Emacs

You can use Emacs for all of your text processing needs, internet and social network interactions, hacking, coding, managing to-do's and organizing your daily schedule, playing Tetris, and many other awesome things. It can even provide you with free psychotherapy and counseling using the built in doctor. A vibrant community of hackers is constantly writing new extensions, thanks to the power of the Emacs Lisp environment.

GNU Emacs is Free Software, both free as in free beer and free as in free speech. The original Emacs was written by St. iGNUcius himself — Richard Stallman.

Not only does it give the user the four essential freedoms, its architecture is built in such a way that you have the power to mold it, change it and make it comply to your computering needs.

Why use Emacs?

Emacs is a very powerful text processor, giving you the power to manipulate documents quickly and efficiently. You can easily move through and edit paragraphs, sentences, words, and logical blocks; blaze through text using powerful search tools; and easily edit thousands of lines at once using regular expressions, keyboard macros and more.

Colorful text editor

Emacs can be customized in every conceivable way, including its looks. You can strip it down, choose between dozens of easy to install themes with M-x load-theme, or even create your own and share it with your friends. Here's a nice gallery of themes.

Et tu, Programmer?

There are tools for every programming language out there. Lisp, Ruby, Python, PHP, Java, Erlang, JavaScript, C, C++, Prolog, Tcl, AWK, PostScript, Clojure, Scala, Perl, Haskell, Elixir all of these languages and more are supported in Emacs. Because of the powerful Lisp core, Emacs is easy to extend to add support for new languages if the urge strikes you.

You get lots of features out of the box, including syntax highlighting, automatic indentation, REPL support, debugging, code browsing, version control integration and much more.

More!

Org mode helps you to keep notes, maintain TODO lists, plan projects and author documents. You can use your Org documents to create HTML websites like this one or export to LaTeX, Beamer, OpenDocuments and many other formats.

Tramp allows you to edit remote files without leaving Emacs. You can seamlessly edit files on remote servers via SSH or FTP, edit local files with su/sudo, and much more.

M-x butterfly unleashes the powers of the butterfly. The real way of programming.

Use the built in IRC client ERC along with BitlBee to connect to your favorite chat services, or use the Jabber package to hop on any XMPP service (like Google Hangouts).

Out of the box Emacs includes a mail client, web browser, calendar, and games; you can even edit video and images inside Emacs. There are more than 2,000 packages for Emacs, and more are written all the time. You can easily extend your Emacs with new packages from GNU ELPA, MELPA and Marmelade repositories.

Installing Emacs

Emacs is easy to install on almost every operating system out there. Officially supported systems include GNU/Linux, Mac OS X, Microsoft Windows, GNU/Hurd, FreeBSD, NetBSD, OpenBSD, and Solaris. You can check out Get Emacs for simple, direct installation directions for your system, or read the following instructions:

GNU/Linux

GNU Emacs is available on every major GNU/Linux distribution. It's available out of the box on several of them, and if it's not you can install it with your system's package manager or download Emacs directly from GNU.

Mac OS X

Emacs is included in Mac OS X, so you can just use Terminal.app, type emacs and you're ready to roll. It's an old version though, and it's recommended that you use the latest stable version. To get the latest and greatest features, there are community built packages like Emacs For OS X or Homebrew that are easy to install.

You can find more info about Emacs on OS X here.

Windows

Windows users can download Emacs for Windows from the GNU servers.

There is also more info on Emacs for Windows on the GNU website.
