EAF, an extensible framework that revolutionizes the graphical capabilities of Emacs

English | 简体中文

A free/libre and open-source extensible framework that revolutionizes the graphical capabilities of Emacs.
The key to ultimately Live in Emacs

Vision

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 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 is the 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 ultimately Live in Emacs.

Install

EAF supports Linux (X11 and Wayland), Windows, macOS and FreeBSD. The installation method is very simple.

1. Download EAF

git clone --depth=1 -b master https://github.com/emacs-eaf/emacs-application-framework.git ~/.emacs.d/site-lisp/emacs-application-framework/

2. Install/Update EAF applications and dependencies

You can use M-x eaf-install-and-update or manually run the install-eaf.py script in the EAF directory:

cd emacs-application-framework
chmod +x ./install-eaf.py
./install-eaf.py

There are many useful flags available for install-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/[email protected] ~/.local/share/gnome-shell/extensions and activate the [email protected] plugin in gnome-extensions
• Sway Wayland Native: jq needs to be installed
• Hyprland Wayland Native

Unity environment support: requires xdotool to be installed.

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 init.el:

(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 browser and pdf-viewer that you installed. Please check Applications for the full list:

(require 'eaf-browser)
(require 'eaf-pdf-viewer)

5. Hooray!

Upgrade

Also, you should regularly git pull and run install-eaf.py (M-x eaf-install-and-update) to update EAF, its applications, and relating dependencies.

Report bug

For any installation and configuration assistance, please read the Wiki and FAQ.

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:

1. Install gdb and turn on option (setq eaf-enable-debug t)
2. Use the command eaf-stop-process to stop the current process
3. Restart eaf, send issue with *eaf* buffer content when next crash

使用出现错误

每个命令都会出现这个错误 eaf exited abnormally with code 1

我想了解这个错误代码1可能是我哪里出现问题了

Suggestion: save eaf buffers in bookmarks

I really enjoy the speed and capabilities of eaf. However, it would be nicer and more user-friendly if we can save eaf buffers in bookmarks (or something similar to bookmarks)
Examples:

• Browser: Save Google homepage in a bookmark so we don't need to manually type eaf-open-url RET https://www.google.com every time when we need to open google.
• PDF Viewer: Save pdf files in a bookmark. When opening a pdf file directly from a bookmark, it goes to the position we saved last time, without manually finding the file. (similar behavior exists in pdf-tools already)
• Same idea goes with video player, image viewer ...

versions of QT & PyQt5

    from app.browser.buffer import BrowserBuffer

    from PyQt5.QtWebKitWidgets import QWebView, QWebPage
ModuleNotFoundError: No module named 'PyQt5.QtWebKitWidgets'

Hi,
QtWebKit got deprecated upstream in Qt 5.5 and removed in 5.6.
You may want to switch to PyQt5.QtWebEngineWidgets

let `eaf-open-camera` support camera taking photograph

I have not found any keybinding actions on eaf-open-camera. Can it support taking photograph and save to file?

And if it can support Emacs' built-in major-mode keybindings [C-h m] to list out current major-mode keybindings/commands will be helpful. I don't know whether this is possible for eaf buffer.

Can eaf based on file manager develop kinds of application?

As a whole computer system , no matter what kinds of version linux, Mac and windows, all based file manager, I think emacs should do this too, espacially for amzoning eaf. For example, before open images or pdfs and other files with application, we first in the file manager, and then hit enter ,it auto run its application.i think if do this ,emacs can be described as the system fact.
As the file manager , the total commander is the best ,but shortcut the vim is the best. so if can combise the vim shortcut and the total commander function to implemente file manager ,eaf may be as described the really computer system

Is this a replacement for Xwidgets?

According to the Emacs wiki, Emacs can use Gtk widgets. Is this project related to the Xwidgets feature?

I don't see you mention this in the document, and I'm curious how this works.

Lose emacs focus when using with EXWM

I use emacs25 in another xserver (run in Xephyr) with exwn. When i try opening eaf, everytime i focus on eaf window, i lose my emacs focus (can't type on emacs).

当窗口焦点位于eaf buffer时，emacs无法用f11切换到全屏

如题所示，如果手动切换焦点到minibuffer，则可以按f11切换到全屏。
此外，如果Emacs已经全屏，反而可以用f11切换回窗口状态。

复现步骤

1. emacs -Q
2. 添加load-path
3. 确保Emacs是窗口状态
4. M-x eaf-open 随便打开什么东西
5. 尝试用f11切换，此时应当切换失败 (Emacs窗口闪烁一下但是没有报错, 也没有切换成功)
6. 把焦点切换到非eaf buffer，进入全屏，焦点回到eaf buffer
7. f11切换，此时应当成功

specify pyqtwebengine as a new dependency

PyQtWebEngine has been moved to its own pypi package since pyqt5.12, see PyQtWebEngine 5.12 on pypi. It seems to be better to specify it as a new dependency.

What is fitz?

I'm missing this dependency, but looking it up on PyPI gives seemingly unrelated results. What packaged do I need to install for this?

As an aside, it would've been great if your setup.py was an actual setup script. At least mention your dependencies there...

BTW. I also had to

pacman -S python-pyqtwebengine qutebrowser

to get some of the missing stuff.

同时开启 "Pdf Viewer" 和 "Video Player"，其中一个会覆盖另一个。
但是两个 app 可以同时运行，用鼠标可以聚焦/操作。应该是再一个 buffer 中。

Feature request: org-mode preview

You're back with an awesome project !
Congratulations :)

I've just seen that you've made a markdown preview.
Do you think it could be possible to have the same for org-mode file ?
It could be an awesome application for Emacs world domination ...

It's perhaps too difficult at present time but a thread was initiated on reddit on this subject with perhaps good ideas to grab as starting point:

https://www.reddit.com/r/emacs/comments/57nps0/orgmode_need_a_realtime_document_preview/

At this time emacs-application-framework was not born, so the world was not the same :)
Anyway many many thanks for this awesome project !

setup issues on Red Hat Enterprise Linux 6

At least python 3.5 is needed. Python 3.4 failed to install pyqt5. So I
had to create virtual environment for python 3.5 on my anaconda
installation.

On RH 6, dbus-daemon is not launched by default. So I had to add the
following bash starupt script:

if [ -z $DBUS_SESSION_BUS_ADDRESS ]; then
    eval `dbus-launch`
    export DBUS_SESSION_BUS_ADDRESS
fi

On RH 6, libc.so version is 2.12, but at least 2.14 is needed.
For now I use RH 7 as a work around.

I thought I would share this information in case you want to update your setup instruction.

*eaf* aborted: core dumped

I’ve installed all the relevant libraries (I’ve tried this both by installing them through pip3 and through the Ubuntu package manager), cloned the repository, added it to my load-path, and evaluated (require 'eaf). I tried loading a page with eaf-open-url (http://sega.com/ to be precise) and it loaded… but before I could click anything or scroll very far, I would get an error, “*eaf* aborted: core dumped”, which would leave me with a blank buffer. (I think the first time I tried this I got the “*eaf* exited abnormally with code 1” error, so this might be related to #32, I’m not sure. But, I tried several more times, and then I always got the “core dumped” error.)

I tried this all again using emacs -Q, and again it loaded the page, but instead of crashing, it… froze my entire system. When I finally got to a terminal (Ctrl+Alt+F1, but it took a while), I ran top and saw that the python3.6 process was using 99% to 100% of my CPU cycles. This is a neat concept for a package, I hope I can get it working 😓

Not working with HiDPI

I am using emacs 26.2 on i3 on Arch Linux. On one machine with normal display (1366x768 on a 14 inch screen), eaf works. However, on the other machine with HiDPI (2560x1440 on a 14 inch screen), eaf is kind of cropped, as shown in the following picture.

To make things worse, the display from eaf totally covers the components from emacs, i.e. scroll bar, modeline, minibuffer, etc. It also blocks all inputs to emacs. I tried wrapping

app = QApplication(sys.argv)

with

        os.environ["QT_AUTO_SCREEN_SCALE_FACTOR"] = "1"
        app = QApplication(sys.argv)
        app.setAttribute(QtCore.Qt.AA_EnableHighDpiScaling)

as suggested by pyat5 and 4k screen, but it didn't work.

I managed to make it work with the following quick hack since I have a scale of 2. Ideally, this number should come from some variable or environmental variable. This can be tricky though: this might involve scaling both from the python side and the emacs side. Since currently PDF is showing a little bit of blur, I guess the proper way of handling would be emacs pass the exact available width/height, while PyQt handles the HiDPI case.

One minor thing that I need to mention is that when an eaf buffer is focused, it does not seem to pass emacs commands to emacs. Since it also happens to my other machine, I guess I should report a separate bug for this?

Is this project still maintained?

i am having hard time installing this package into emacs 26, any guidance?

When I try to open a pdf file, minibuffer gives this error:*eaf* exited abnormally with code 1

This is what I am seeing in *eaf* buffer:

this and that didn't solve the problem.

Can you please guide on adding custom widgets?

I m trying to build an svg browser and editor... which will allow me render svg from plantuml or graphvz. after roaming from various sources i remember you had something similar which is able to render Qt into emacs buffer,

can you please advise on how can i perform the same thing to display the graph engine into emacs buffer ?

按照 #30 的方法重装 pyqt5 也没有效果，但我是一直可以打开 pdf。

我感觉是依赖问题，因为在我的家里和公司的两台电脑上都复现了，打开video是提示别的。。。

两台电脑上都是装的 ArchLinux 虚拟机，没有装桌面环境，只装了自己需要的一些软件，不知道还缺少什么依赖。。。

Mention system Qt packages needed for running eaf

Full-blown vs keyboard oriented browser/nav

Hi, thank you for bringing eaf.

Regarding browser navigation (and perhaps other plugins), are you planning a GUI approach as well
(URI / reload / navigation buttons);

or whether a strictly keyboard approach (vimium..)

perhaps both ..?

Support for Wayland

Hi,

I have tried it on Wayland. It does not work.
Is there any plan to support wayland?

PDF viewer doesn't work well with multi frames

执行 make-frame-command 然后用 other-frame 跳到别的 frame 上随便执行一些操作，原来的 eaf pdf viewer buffer 会丢失当前显示的内容。

建议让呈现出来的PDF里的文字可选

MacOS install?

Docs reference:

sudo pacman -S python-xlib python-pyqt5 python-pymediainfo
sudo pip install git+https://github.com/wbsoft/python-poppler-qt5.git

Could somebody provide a way to install this on Mac via brew or any other given source?

Thanks,
Ryan

并且不知道被哪个包影响了，eaf-open 时补全提示始终带有本机路径，无法正常输入网址，推测可能是ivy.
