A free/libre and open-source extensible framework that revolutionizes the graphical capabilities of Emacs.
The key to ultimatelyLive in Emacs
Emacs, the extensibletext editor, is more than 45 years old. It is older than virtually all operating systems people use today, almost as old as the first UNIX system. During the decades of development, the world's brightest hackers have contributed their intelligence and creativity. Together they've constructed the most comprehensive and richest ecosystem that you can find in any software to date.
If you are a hacker who works with numerous languages and text, who's keyboard-driven and desires maximum freedom, extensibility, and introspectivity over your tool, maybe to the extent ofliving in it, Emacs will be your best bet.
Unfortunately, this 45 years of age is also one of the greatest disadvantages of Emacs. Comparing with modern software, Emacs lacks performance. Specifically Emacs Lisp lacks performance. It doesn't have proper multithreading and its graphical capabilities are seriously limited. It is far from what you'd expect from any GUI application today (such as IDEA or VSCode). You may think that Emacs, as a text-centric editor, doesn't need them, but have you ever run into a situation that, you sit comfortably typing commands and doing your Emacs sorcery, but can't help but ponder:
What if Emacs had a real browser?What if this PDF or video file could be viewed efficiently without leaving Emacs?
Emacs, although infinitely extensible in text, is very limited in graphics. It shouldn't have to be this way. However, Emacs Lisp isthe integral part of the Emacs culture, it carries decades of history with itself, it is what makes Emacs special. It is irreplaceable.
The vision of the Emacs Application Framework (EAF) project is, while fully retaining the rich history, culture, and ecosystem of Emacs and Emacs Lisp, to open up completely new doors to the ecosystems of Python, Qt6, and even JavaScript. EAF extends Emacs to the world of modern graphics, but still preserving the extensibility and customizability of Emacs. It will be the key to ultimatelyLive in Emacs.
EAF is very extensible. We ship a lot of applications, feel free to choose anything you find interesting to install:

EAF supports Linux (X11 and Wayland), Windows, macOS and FreeBSD. The installation method is very simple.
git clone --depth=1 -b master https://github.com/emacs-eaf/emacs-application-framework.git~/.emacs.d/site-lisp/emacs-application-framework/
You can useM-x eaf-install-and-update
or manually run theinstall-eaf.py
script in the EAF directory:
cd emacs-application-frameworkchmod +x ./install-eaf.py./install-eaf.py
There are many useful flags available forinstall-eaf.py
, check it yourself using--help
.
There are four types of support for the Wayland environment:
- XWayland: EAF can run directly under XWayland
- Gnome3 Wayland Native: You need to execute the command
cp -r emacs-application-framework/gnome-shell/eaf-wayland@emacs-eaf.org ~/.local/share/gnome-shell/extensions
and activate theeaf-wayland@emacs-eaf.org
plugin ingnome-extensions
- Sway Wayland Native: jq needs to be installed
- Hyprland Wayland Native
Unity environment support: requiresxdotool
to be installed.
From here on, you can add the full path to the EAF installation directory to your Emacsload-path
, then add the following toinit.el
:
(add-to-list'load-path"~/.emacs.d/site-lisp/emacs-application-framework/")(require'eaf)
Alternatively, if you useuse-package, you can use the followingsample configuration for your convenience.
(use-package eaf:load-path"~/.emacs.d/site-lisp/emacs-application-framework":custom; See https://github.com/emacs-eaf/emacs-application-framework/wiki/Customization (eaf-browser-continue-where-left-offt) (eaf-browser-enable-adblockert) (browse-url-browser-function'eaf-open-browser):config (defalias'browse-web#'eaf-open-browser) (eaf-bind-key scroll_up"C-n" eaf-pdf-viewer-keybinding) (eaf-bind-key scroll_down"C-p" eaf-pdf-viewer-keybinding) (eaf-bind-key take_photo"p" eaf-camera-keybinding) (eaf-bind-keynil"M-q" eaf-browser-keybinding));; unbind, see more in the Wiki
You can use below code to load applicationsbrowser
andpdf-viewer
that you installed. Please checkApplications for the full list:
(require'eaf-browser)(require'eaf-pdf-viewer)
Congratulations, you just installed EAF! You can tryM-x eaf-open-demo
(that is if you havedemo
installed, of course) to see if everything works properly, and enjoy the new possibilities of Emacs.

- EAF Browser and PDF Viewer support Emacs built-in bookmark operation, with
M-x bookmark-set
(defaulted toC-x r m
) andM-x bookmark-bmenu-list
(defaulted toC-x r l
).
Also, you should regularlygit pull
and runinstall-eaf.py
(M-x eaf-install-and-update
) to update EAF, its applications, and relating dependencies.
If you encounter a problem with EAF, and it occurred after pulling the latest commit, please check theMandatory Procedures to Keep Your EAF Up-To-Date pagefirst.
For any other problems, please useemacs -q
and load a minimal setup with only EAF to verify that the bug is reproducible. Ifemacs -q
works fine, probably something is wrong with your Emacs config.
If the problem persists, please report ithere with the*eaf*
buffer content. It contains many clues that can help us locate the problem faster.
If you get a segfault error, please use the following way to collect crash information:
- Install gdb and turn on option
(setq eaf-enable-debug t)
- Use the command
eaf-stop-process
to stop the current process - Restart eaf, send issue with
*eaf*
buffer content when next crash
