+# RaptDrama Download Tools
+
+Windows 桌面程序，用来登录 RaptDrama、浏览剧目、播放已缓存的分集，以及把剧集下载成 MP4。
+
+## 使用分发包
+
+1. 解压 `dist/RaptDrama-Download-Tools-windows-x64.zip`。
+2. 进入 `RaptDrama-Download-Tools`，运行 `raptdrama.exe`。
+3. 压缩包里已经带有 Python、adb、ffmpeg 和 WebView2 离线安装包。本机如果还没有 WebView2，程序启动时会静默安装。
+
+程序会在自己的目录里写入：
+
+- `download/`：下载下来的视频
+- `cache/`：封面、剧目清单和分集播放地址
+
+分集播放地址会留在缓存里。账号还能拿到新地址时会更新缓存；VIP 失效后，缓存里已经有地址的集仍然可以播放。签名过期的地址无法继续播放。
+
+关闭窗口时，如果还有未完成的下载，会先询问。确定后才会退出。
+
+## 开发
+
+需要 Windows、Node.js、Rust 和 Python 3.13。
+
+```powershell
+python -m venv server\.venv
+server\.venv\Scripts\python.exe -m pip install -r server\requirements.txt
+npm install
+npm install --prefix ui
+npm run tauri dev
+```
+
+开发时界面和后台都从仓库目录读取。剧目清单默认使用 `cache/catalog.json`，正式打包会关掉这份缓存。封面缓存和分集地址缓存会保留。
+
+## 打包
+
+在仓库根目录执行：
+
+```powershell
+python scripts\package.py
+```
+
+脚本会编译界面和桌面程序，并把本地已经放好的文件拷进压缩包：
+
+- `dist/cache` 里的 Windows 嵌入式 Python，以及 `server/requirements.txt` 里的依赖
+- `vendor/platform-tools` 里的 adb，拷到压缩包的 `tools/platform-tools`
+- `tools/ffmpeg/ffmpeg.exe`
+- `vendor/webview2/MicrosoftEdgeWebView2RuntimeInstallerX64.exe`
+
+adb 和 WebView2 打包时不再下载。完成后得到 `dist/RaptDrama-Download-Tools-windows-x64.zip`。
+
+打包脚本是 Python，公共步骤和平台相关的运行时是分开的。目前只接好了 Windows。macOS 和 Linux 以后把对应文件放进 `vendor` 即可。
