prism-keyboard

A utility for changing the system keyboard layout on the fly. It provides a comprehensive, searchable list of all available X11 keyboard layouts (e.g., US, German, Dvorak) via 08 Rofi. When a selection is made, the change is applied instantly to the current session and saved permanently to the 01 Hyprland configuration.

How it works

1. Discovery: The script locates the base.lst rules file provided by the xorg.xkeyboardconfig package. This file serves as the master list of valid keyboard layouts on Linux.
2. Parsing: It uses awk to extract layout codes (like us, de, fr) and their full descriptions (like "English (US)", "German") from the rules file. If the file is missing (rare), it falls back to a short list of common layouts.
3. Selection: The list is piped into rofi, allowing the user to search by country name or language (e.g., typing "Italy" finds the it code).
4. Application:
   • Immediate: Uses hyprctl keyword input:kb_layout <code> to switch the layout instantly without restarting the session.
   • Permanent: Uses sed to update the kb_layout line in $HOME/.config/hypr/input.conf, ensuring the choice persists after a reboot.
5. Feedback: Sends a desktop notification confirming the new layout.
