216.171.97.194: /* Text editing in Emacs */

'''Welcome to WikEmacs - A Community Maintained Emacs Wiki'''

Useful resources for working with [http://www.gnu.org/software/emacs/emacs.html GNU Emacs], the extensible, self-documenting text editor. See also [http://en.wikipedia.org/wiki/Emacs Emacs (Wikipedia)].

Emacs is [https://en.wikipedia.org/wiki/Free_software free software (Wikipedia)].

WikEmacs (pronounced wikimacs) is intended as a next generation alternative to the traditional [http://www.emacswiki.org/ EmacsWiki].

See [[WikEmacs:Guidelines]] for information on editing this wiki.

== Getting started with Emacs ==

The latest stable release is [[:Category:Emacs-23.4|Emacs-23.4]]. The next major release is [[:Category:Emacs-24.1|Emacs-24.1]] and is in ''Pretest'' stage.

Emacs is available on all popular [[:Category:Operating System | Operating Systems]] including [[GNU/Linux]], [[OSX]] and [[Windows]]. It supports variety of [[:Category:Programming languages|Programming languages]].

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

== Emacs for Development ==

You can use Emacs to program in variety of [[:Category:Programming languages|Programming languages]]. If you don't see an entry for your favorite language, please create an page for it and few words about it.

=== Markup Languages ===

* [[CSS]]
* [[HTML]]
* [[JSON]]
* [[Markdown]]
* [[SGML]]
* [[XML]]

=== Compiling ===

* [[ flymake ]]

=== Debugging ===

=== REPLs ===

Interactive command-line environments for Lisp. ('''R'''ead-'''E'''val-'''P'''rint-'''L'''oop)

* [[ 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 [http://cedet.sourceforge.net/ CEDET]. See [http://alexott.net/en/writings/emacs-devenv/EmacsCedet.html Gentle Introduction to CEDET].

For Literate Programming see [http://orgmode.org/worg/org-contrib/babel/ 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 ==
* [[ Org ]] Mode
* [[ calc ]]
* [[ calendar ]]
* [[ notification ]]
* [[ diary ]]
* Contacts: [[ bbdb ]]

== Communication ==

* [[ Blogging ]]
* [[ Chat ]]
* [[ Email ]]
* [[ Feed reading ]]
* [[ Microblogging ]]
* [[ Usenet news ]]

== Web browsing ==

* 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.

See also [[:Category:Workflow:Browsing|Workflow:Browsing]]

== 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 ==

* [http://emacspeak.sourceforge.net/ Emacspeak] for the visually challenged.

== Security and cryptography ==

* [[ Gnu Privacy Guard ]] (GPG) support and integration

== Getting Involved ==
* IRC Channel

* [[ Mailing list archives ]]

* [http://bzr.savannah.gnu.org/lh/emacs/trunk/files Browsable source repository]

Emacs includes an optional client-server architecture.

To start the server, run <code>server-start</code>. If you want to use this feature it probably makes sense to do this somewhere in your configuration files.

Once this is done you may use the <code>emacsclient</code> command outside of Emacs to send a file to Emacs for editing, e.g. <code>emacsclient ~/.emacs.d/init.el</code> to modify your init file. On a GNU/Linux system it might be a good idea to set your <tt>EDITOR</tt> environment variable to <tt>emacsclient</tt>.

Once you have finished with a buffer that was opened via <tt>emacsclient</tt> you should use the <code>C-x #</code> (<code>server-edit</code>) to properly close the loop. Killing the buffer normally will not send the signal to <tt>emacsclient</tt> that Emacs has finished with the file.
