From 0aacad31f4bdb547ab3882c2c640f0c595d565c2 Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Fri, 12 Sep 2025 22:26:38 +0100 Subject: [PATCH] emblemscanner: add camera rules, web-view fallback, and loading state MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major enhancements to the emblemscanner module: **Camera System:** - Device-specific camera rules from Themblem API - Web-view fallback for problematic devices in same page - Loading spinner prevents camera mode jumping - Debug mode with comprehensive diagnostics **Self-contained Architecture:** - Inline utility functions (no external dependencies) - Camera rule matching and API integration - Web-view URL generation with proper parameters - Message handling for web-view QR results **UI Improvements:** - Hide overlays during loading state - Enhanced debug overlay with camera rule info - Worker/native camera mode detection - Loading feedback with "初始化相机..." message Module is now production-ready for camera setup and UI, with framework for QR processing integration. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- scanner/QR_SCANNER_MODULE_PROGRESS.md | 94 ++++---- scanner/pages/emblemscanner/emblemscanner.js | 200 +++++++++++++++--- .../pages/emblemscanner/emblemscanner.wxml | 24 ++- .../pages/emblemscanner/emblemscanner.wxss | 31 +++ 4 files changed, 262 insertions(+), 87 deletions(-) diff --git a/scanner/QR_SCANNER_MODULE_PROGRESS.md b/scanner/QR_SCANNER_MODULE_PROGRESS.md index e5bb1e0..4857041 100644 --- a/scanner/QR_SCANNER_MODULE_PROGRESS.md +++ b/scanner/QR_SCANNER_MODULE_PROGRESS.md @@ -17,8 +17,9 @@ Create a self-contained, portable QR scanning page module that can be easily int ### ✅ Camera System -
