# A script to display Hyprland keybindings defined in your configuration

# --- CONFIGURATION ---
# Set the path to your keybindings file.
# The script will check keybindings in 'hyprland.conf'.
HYPRLAND_CONF="$HOME/.config/hypr/hyprland.conf"

# Determine which configuration file to use

# Process the configuration file to extract and format keybindings
# 1. `grep` finds all lines starting with 'bind' (allowing for leading spaces).
# 2. The first `sed` removes comments (anything after a '#').
# 3. `awk` does the heavy lifting of formatting the output.
#    - It sets the field separator to a comma ','.
#    - It removes the 'bind... =' part from the beginning of the line.
#    - It joins the key combination (e.g., "SUPER + Q").
#    - It joins the command that the key executes.
#    - It prints everything in a nicely aligned format.
# 4. The final `sed` cleans up any leftover commas from the end of lines.
