About

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

This wiki is intended as a next generation replacement for Emacswiki

Getting started with Emacs

• Installing Emacs
• Look and Feel
• Emacs for Vim users
• Starter Kits
• Learning Resources and getting help
• Package Managers
• Emacs Terminology
  • Buffer
  • Windows and frames
  • Point and mark
  • Kill and Yank
  • Region
  • Fill
  • Case-fold
  • Narrow and widen
• Quitting Emacs: type `C-x C-c` (that's Control-X, Control-C)

Text editing in Emacs

• Search and replace
• Undo and redo
• Abbreviations and Templates
• Auto-completion
• Spell check
• International Users
• Remote Editing via FTP, ssh, etc.
• Emacs server and emacsclient

Automation in Emacs

• Keyboard macros
• Emacs Lisp

Configuring Emacs

• Custom for choosing and setting options.
• Scripting your init.el file (formerly .emacs) using Emacs Lisp .

Emacs and Desktop Integration

• Dired
  • Archive mode
• Battery
• Notifications

Typesetting, Document Markup and Document Creation in Emacs

• Markdown
• org-mode export to HTML, PDF etc
• SGML , HTML and XML
• TeX, LaTeX, TeXinfo, BibTeX etc.

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

• Ada
• antlr
• asm
• awk
• C/C++
• Clojure
• Common Lisp
• Emacs Lisp
• Fortran
• Groovy
• Haskell
• Icon
• IDL
• Java
• JavaScript
• make
• Modula2
• OCaml
• Octave
• Pascal and Delphi
• perl
• PHP
• PostScript
• Prolog
• Python
• Ruby
• Scala
• Scheme
• shell script
• Simula
• SQL
• tcl
• Visual Basic

Markup Languages

• CSS
• HTML
• JSON
• Markdown
• SGML
• XML

Compiling

• flymake

REPLs

• 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

• bzr can be managed using dvc
• Clearcase
• CVS can be managed using vc
• git can be managed using dvc or magit
• Mercurial can be managed using dvc
• SVN can be managed using vc
• RCS can be managed using vc

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 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

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

• Gnu Privacy Guard (GPG) support and integration

Getting Involved

• IRC Channel

• Mailing list archives

• Browsable source repository
