I want a pop-up window display web multimedia content, such as, translation tooltip, LaTex preview, code completion etc.

Browser related technology comes from my other project Emacs Application Framework

1. Make sure install PyQt5 from your operating system repository (DON'T install PyQt5 from pip, otherwise browser will crash)
2. Install library python-epc
3. Clone or download this repository (path of the folder is the <path-to-popweb> used below).
4. In your ~/.emacs, add the following two lines:

(add-to-list 'load-path "<path-to-popweb>") ; add popweb to your load-path
(require 'popweb-dict-bing)
(require 'popweb-dict-youdao)
(require 'popweb-katex)

• popweb-dict-bing-input: popup input translation window with Bing
• popweb-dict-youdao-input: popup input translation window with Youdao
• popweb-dict-bing-pointer: popup pointer translation window with Bing
• popweb-dict-youdao-pointer: popup pointer translation window with Youdao
• popweb-katex-show: show LaTex preview
• popweb-katex-update: update LaTex preview
• popweb-katex-hide: hide LaTex preview

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")
