This repository combines all the scripts I had to develop for efficient language learning on Linux. They are probably quite specific to modern Debian/Ubuntu with KDE, so please see them as a source of inspiration rather than a finished product. That said, the KDE-specific parts (for example) can be easily replaced if you know your own desktop environment decently well! Most of the core logic will probably work on any modern Linux system.
Please see the header section of each script for any specific requirements.
It should be fine to simply drop the scripts you want to use into your system's /opt/ directory and make them executable.
Call them on specific shortcut presses, execute them as a systemd service on appropriate events or just execute them manually when needed.
I developed this collection of scripts in the early phases of my own language learning and certainly saved myself a lot of hassle through this. However, I cannot guarantee that you will be equally satisfied with it. Please consider creating an issue or a pull request if you know how to do it better. If my contribution eased your language learning experience or you want me to help you with a specific problem more quickly, consider donating as much as you feel I deserve!
