Typesetting, Document Markup and Document Creation in Emacs

Emacs supports a wide range of Markup languages to help you in your workflow of document creation.

Debugging

gdb

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

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

Communication

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.

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.

Accessibility

Emacspeak for the visually challenged.

Security and cryptography

Gnu Privacy Guard (GPG) support and integration
