EAF is a GUI application framework that revolutionizes Emacs graphical capabilities to ultimately Live in Emacs.
EAF is an extensible framework, one can develop any Qt5 application and integrate it into Emacs.

- EAF talk & demo at EmacsConf2020, presented to you by MatthewZMD
- Homepage (Q&A included): https://emacsconf.org/2020/talks/34/
- Youtube link:
- Download EAF
git clone --depth=1 -b master https://github.com/manateelazycat/emacs-application-framework.git ~/.emacs.d/site-lisp/emacs-application-framework/
Alternatively, you can use a Quelpa recipe
(quelpa '(eaf (:fetcher github
:repo "manateelazycat/emacs-application-framework"
:files ("*"))))
- Install EAF dependencies using
M-x install-eaf-dependencies
.
If you prefer to manually call the installation script in the terminal,
- If you use GNU/Linux,
cd emacs-application-framework
chmod +x ./install-eaf.sh
./install-eaf.sh
- If you use Windows,
cd emacs-application-framework
node ./install-eaf-win32.js
Feel free to inspect the install script yourself. An explanation of each dependency can be found at Dependency List.
- Install Elisp packages:
- From here on, you can either add the full path to the EAF installation directory to your Emacs
load-path
, then add the following toinit.el
:
(add-to-list 'load-path "~/.emacs.d/site-lisp/emacs-application-framework/")
(require 'eaf)
or, if you use use-package, you can use the following sample configuration for your convenience.
(use-package eaf
:load-path "~/.emacs.d/site-lisp/emacs-application-framework" ; Set to "/usr/share/emacs/site-lisp/eaf" if installed from AUR
:init
(use-package epc :defer t)
(use-package ctable :defer t)
(use-package deferred :defer t)
(use-package s :defer t :ensure t)
:custom
(eaf-browser-continue-where-left-off t)
:config
(eaf-setq eaf-browser-enable-adblocker "true")
(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-key nil "M-q" eaf-browser-keybinding)) ;; unbind, see more in the Wiki
Packages listed as Core are mandatory for EAF to work, whereas other packages are optional - install if you want to use corresponding EAF Application.

- 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
).
It is highly suggested to read the Wiki first before using EAF.
Wiki consists of documentations on:
- Keybindings
- Customization
- Design
- TODOLIST
There also are some helpful tips to make EAF work with Docker, Helm, etc.
EAF implements three major functionalities:
- Integrate PyQt program window into Emacs frame using QWindow Reparent technology.
- Listen to EAF buffer's keyboard event flow and control the keyboard input of PyQt program via Python EPC.
- Create a window compositer to make a PyQt program window adapt Emacs's Window/Buffer design.
Learn more from the Wiki!
- EAF and EXWM share a common goal: enhance collaboration between the standard GNU Emacs with other GUI tools.
- EXWM is an X11 Window Manager, it manages and controls other software using a keyboard, but it cannot modify, customize and extend the behavior of other software.
- EAF is not a Window Manager, it utilizes the windows managing capabilities of Emacs to display its applications.
- The intention of EAF is to provide a framework to write PyQt5 applications that extends the multimedia experience of Emacs. From the perspective of Emacs' buffer/mode design, EAF is not different from any other package, with the former uses Qt for drawing contents while the latter uses Emacs' built-in text libraries instead.
- Through EAF's design, one can use Elisp to control Python and vice versa, and even able to use Elisp to control JavaScript in EAF Browser. EAF enables Emacs to the world of multi-language scripting.
Both projects are similar in terms of interface, but they are two completely different projects with different goals in mind. Sometimes one may find EAF is more suitable than EXWM, sometimes it's the other way around. Please do not meaninglessly compare them.
- Qt5's QGraphicsScene technology does not work on MacOS.
- QWindow Reparent technology need use the original API of Mac platform for replacement.
If you've figure them out, PRs are always welcome!
EAF confirms that the desktop environment or window manager you can work includes: KDE, GNOME2, GNOME3, Mate, Xfce, LXDE, I3, QTILE, Xpra.
We suspect there are some issues with how all the Window Managers implement their x11 protocols.
One workaround is to name of command wmctrl -m
to the elisp list eaf-wm-focus-fix-wms
. Fill an issue if it still doesn't work.
If you use EAF Markdown Previewer, to get consistent previewing, you need to access Github Personal access token site, fill something in "Token description" and click button "Generate token" to get your personal token. Then set the token:
(setq eaf-grip-token "yourtokencode")
Although Markdown Previewer works for the first few times by entering empty string when prompted, eventually it stops working and gives "GitHub Rate Limit Reached" error.
If you need to use proxy to access internet, one can configure the proxy settings.
(setq eaf-proxy-type "http")
(setq eaf-proxy-host "127.0.0.1")
(setq eaf-proxy-port "1080")
If you use Socks5 as local proxy, one can set proxy type with:
(setq eaf-proxy-type "socks5")
A list of other community packages that use EAF to enhance their graphical experiences!
If we missed your package, please make a PR to add it to the list.
For any installation and configuration assistance, please read the Wiki first!
If you encounter a problem with EAF, and it occured after pulling the latest commit, please check the Discussions page first.
For any other problems, please use emacs -q
and load a minimal setup with only EAF to verify that the bug is reproducible. If emacs -q
works fine, probably something is wrong with your Emacs config.
If the problem persists, please report it here with *eaf*
buffer content, it contains many clues that can help us locate the problem faster.
If you got segfault error, please use the following way to collect crash information:
- Install gdb and turn on option
eaf-enable-debug
- Use command
eaf-stop-process
stop current process - Restart eaf, send issue with
*eaf*
buffer content when next crash
