# Keys Pagination System for Owner & Admin Bots
# Add this code to nitro_system/bots.py
# ═══════════════════════════════════════════════════════════════

# CONFIGURATION
KEYS_PER_PAGE = 8  # عدد المفاتيح في كل صفحة

# ═══════════════════════════════════════════════════════════════
# 1. Add to LANG["ar"] dictionary:
# ═══════════════════════════════════════════════════════════════

"page_info": "📄 صفحة {current} من {total}",
"next_page": "التالي ➡️",
"prev_page": "⬅️ السابق",
"no_more_pages": "لا توجد صفحات أخرى",

# ═══════════════════════════════════════════════════════════════
# 2. Add to LANG["en"] dictionary:
# ═══════════════════════════════════════════════════════════════

"page_info": "📄 Page {current} of {total}",
"next_page": "Next ➡️",
"prev_page": "⬅️ Previous",
"no_more_pages": "No more pages",

# ═══════════════════════════════════════════════════════════════
# 3. Add to LANG["ru"] dictionary:

"page_info": "📄 Страница {current} из {total}",
"next_page": "Далее ➡️",
"prev_page": "⬅️ Назад",
"no_more_pages": "Больше нет страниц",

# 8. Handle page_info callback (does nothing, just for display):
# ═══════════════════════════════════════════════════════════════

elif q.data == 'page_info':

# ═══════════════════════════════════════════════════════════════
# End of patch
# ═══════════════════════════════════════════════════════════════

# NOTES:
# - KEYS_PER_PAGE = 8 means 8 keys per page (you can change this)
# - Pagination works for:
#   * Owner: All Keys view
#   * Admin: My Keys view
#   * Admin: Ban Key selection
# - Navigation buttons appear only when needed
# - Page info shows current page / total pages
# - Keys are displayed with full details (IP, expiry, status)
