# 用途: 修复 qBittorrent 核心包的 libtorrent 依赖关系，
#       将过时的 +rblibtorrent 替换为正确的 +libtorrent-rasterbar。
# 依赖: 需要预先 source common/scripts/libs/index.sh 以使用 log 函数
#       若单独使用，脚本内置了日志后备
# 用法:
#   source common/scripts/mods/fix-qbittorrent-deps.sh
#   fix_qbittorrent_deps [base_path]
#
# 参数:
#   base_path : qbittorrent 自定义软件包的基础路径，默认为 'custom-packages/qbittorrent'

# 修复 qBittorrent 的 libtorrent 依赖
#
# 功能:
#   检查 qbittorrent 核心包的 Makefile，确保其依赖中包含 +libtorrent-rasterbar。
#   - 如果已存在正确依赖，则跳过。
#   - 如果存在旧依赖 +rblibtorrent，则替换为 +libtorrent-rasterbar。
#   - 若都不存在，则在 DEPENDS 行末尾追加 +libtorrent-rasterbar。
#
# Arguments:
#   $1 - (可选) qbittorrent 软件包的基础路径，默认为 'custom-packages/qbittorrent'
#
# Examples:
#   fix_qbittorrent_deps
#   fix_qbittorrent_deps 'custom-packages/qbittorrent'
