A free/libre and open-source extensible framework that revolutionizes the graphical capabilities of Emacs.
The key to ultimately Live in Emacs
Emacs, the extensible text 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 of living 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 has a real browser? What if this PDF or video file can 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 is the integral part of the Emacs culture, it carries decades of history with itself, it is what makes Emacs special. It is irreplaceable.

3. Load EAF Core
From here on, you can add the full path to the EAF installation directory to your Emacs
load-path, then add the following to
(add-to-list 'load-path "~/.emacs.d/site-lisp/emacs-application-framework/") (require 'eaf)
Alternatively, 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" :custom ; See https://github.com/emacs-eaf/emacs-application-framework/wiki/Customization (eaf-browser-continue-where-left-off t) (eaf-browser-enable-adblocker t) (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-key nil "M-q" eaf-browser-keybinding)) ;; unbind, see more in the Wiki
4. Load EAF Apps
You can use below code to load applications
pdf-viewer that you installed. Please check Applications for the full list:

If you encounter a problem with EAF, and it occurred after pulling the latest commit, please check the Mandatory Procedures to Keep Your EAF Up-To-Date 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 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-processto stop the current process
- Restart eaf, send issue with
*eaf*buffer content when next crash
