Using the Deepl API, this python script will grab the selected text with xclip and make a translate request to the API. It will show the translated text in a small popup window next to the mouse cursor. Left click to dismiss it. You need to create a Deepl account, the API is free for 500 000 characters per months. If you have a pro plan, change the API endpoint accordingly in the configuration file.

You need to create a config file at $XDG_CONFIG_HOME/deeplinux/deeplinux.toml (usually $HOME/.config/deeplinux/deeplinux.toml) and add the following:

[quicktranslate]
DEEPL_AUTH_KEY = "api_key_here"
DEEPL_API_ENDPOINT = "https://api-free.deepl.com/v2/translate"
TARGET_LANG = "EN"

For example, on Hyprland, you can bind it as: $mod, T, exec, quicktranslate

Logs are located in $XDG_STATE_HOME/deeplinux/deeplinux.log (usually $HOME/.local/state/deeplinux/deeplinux.log)
