# 自动 hook:i18n 完整性。
# 在 commit 前,如果改动触及 lang/、使用 $lang() 的 .vue/.js,或 lang-bundle.json,
# 就跑一次审计,真问题会拦下 commit。
#
# 启用方法:
#   1) 项目根已有 .husky/pre-commit(本脚本)
#   2) 把这个 commit-msg / pre-commit 加入 husky 钩子(本仓库用 simple-git-hooks
#      或 husky 都行,本脚本不依赖特定框架)
#
# 也可以在 CI 跑:
#   python scripts/i18n_audit.py --strict

set -e

# 检测本次 diff 是否触动相关文件
