Please note that the source code used for the build here originates from my modified source code.
I added Deepl translation support, Subtext, translation engine icon (only present here) to the original project.
Here is the source code for the build:
https://github.com/shenghuang147/krunner-translator

This is a plugin for Plasma 5 KRunner. It's a translator and it translates text. Currently Google Translate, Bing Translator, Deepl Translate, youdao, and Baidu Fanyi are supported. By clicking on the corresponding icon, the translation can be copied or read aloud.
