REM  Marp 演示批量导出脚本 (Windows)
REM ====================================================
REM 用途：一键导出 Active 目录下所有演示
REM 使用方法：
REM   1. 确保已安装 Marp CLI: npm install -g @marp-team/marp-cli
REM   2. 双击运行此脚本
REM   3. 导出结果在 Export 目录
REM ====================================================

setlocal EnableDelayedExpansion

REM 配置
set "PRESENTATIONS_DIR=%~dp0Active"
set "EXPORT_DIR=%~dp0Export"
set "TIMESTAMP=%date:~0,4%-%date:~5,2%-%date:~8,2%"

REM 创建导出目录
if not exist "%EXPORT_DIR%" mkdir "%EXPORT_DIR%"
if not exist "%EXPORT_DIR%\PDF" mkdir "%EXPORT_DIR%\PDF"
if not exist "%EXPORT_DIR%\PPTX" mkdir "%EXPORT_DIR%\PPTX"
if not exist "%EXPORT_DIR%\HTML" mkdir "%EXPORT_DIR%\HTML"
