I always wanted a fast and responsive pop-up window to display multimedia content in Emacs, this includes web translation tooltip, LaTeX preview for math equations, code completion, color picker, etc. The creation and success of the Emacs Application Framework gave a solid foundation for this to happen.

I consider popweb to be a sister project, and a lightweight version of EAF that particularly focuses on multimedia popup functionality, some portion of code is shared between the two projects.

1. Install PyQt6: pip install PyQt6 PyQt6-Qt6 PyQt6-sip PyQt6-WebEngine PyQt6-WebEngine-Qt6 (macOS need install pyobjc additionally)
2. Install python-epc: pip install epc sexpdata
3. Install browser_cookie3(optional, for import cookies from browser): pip install browser_cookie3
4. Clone or download this repository (path of the folder is the <path-to-popweb> used below).
5. In your ~/.emacs, add the following lines:

(add-to-list 'load-path "<path-to-popweb>") ; add popweb to your load-path
;; Org-Roam ID link and footnote link previewer
(add-to-list 'load-path "<path-to-popweb>/extension/org-roam")
(require 'popweb-org-roam-link)
;; LaTeX preview functionality
(add-to-list 'load-path "<path-to-popweb>/extension/latex")
(require 'popweb-latex)
(add-hook 'latex-mode-hook #'popweb-latex-mode)
;; Chinese-English translation popup
(add-to-list 'load-path "<path-to-popweb>/extension/dict") ;
(require 'popweb-dict)
;; Anki note review popup
(add-to-list 'load-path "<path-to-popweb>/extension/anki-review")
(require 'popweb-anki-review)

If you need to use a proxy to access the internet, one can configure the proxy settings.

(setq popweb-proxy-type "http")
(setq popweb-proxy-host "127.0.0.1")
(setq popweb-proxy-port "1080")

If you use Socks5 as a local proxy, one can set proxy type with:

(setq popweb-proxy-type "socks5")

If you think the font of popup web page is too small, you can change value of popweb-zoom-factor.

(setq popweb-zoom-factor 1.5)

(setq popweb-org-roam-link-popup-window-width-scale 0.8)
(setq popweb-org-roam-link-popup-window-height-scale 0.5)

Popup window scales to Emacs's.

You can choose either scaled to emacs or in pixes by customizing

(setq popweb-url-web-window-size-use-absolute t)

(setq popweb-url-web-window-width-scale 0.8)
(setq popweb-url-web-window-height-scale 0.45)

Popup window scales to Emacs's.

(setq popweb-url-web-window-width-absolute 480)
(setq popweb-url-web-window-height-absolute 270)

Popup window's size in pixels

If you when to play Anki note sound file, configure the Anki media direction.

(setq popweb-anki-review-media-directory <path-to-Anki-media-directory>)

then install python playsound package.

python3 -m pip install playsound

Customize callback method, for example:

(setq popweb-anki-review-callback "popweb-dict-eudic-dicts-input")

You can set option popweb-enable-developer-tools with t, then you can debug popweb page like normal browser does.

Please use emacs -q and load a minimal setup with only popweb 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 *popweb* 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 popweb-enable-debug
2. Use the command popweb-stop-process to stop the current process
3. Restart popweb, send issue with *popweb* buffer content when next crash
