# translate-wl — Translate selected text using translate-shell
#                with Wayland clipboard (wl-clipboard)
#
# Replaces the old ratflow trans-xsel script (X11 xsel-based).
# Uses wl-paste to get clipboard content and wl-copy to write
# the translation back, plus a notification via notify-send
# (which works with mako/swaync on Wayland).
#
# Usage:
#   translate-wl en:pl   — translate English to Polish
#   translate-wl pl:en   — translate Polish to English
#   translate-wl de:en   — translate German to English, etc.
#
# Workflow:
#   1. Select text (it goes to Wayland primary/clipboard)
#   2. Press the bound key (e.g. $mod+t)
#   3. Script reads selection via wl-paste, translates,
#      shows notification, and copies result to clipboard
#
# Dependencies: translate-shell (trans), wl-clipboard, libnotify
