+ +--- + +Perfect! Now I have implemented the hierarchical structure for indirectly linked blends. Here's what the new system provides: + +## ✅ **Enhanced Hierarchical Display:** + +### **Direct Links (Main Libraries):** +- Each directly linked blend gets its own box +- Shows the library name, filepath, and Open button +- Red highlighting if the library itself is missing + +### **Indirect Links (Nested Under Parent):** +- **No separate boxes** - they're contained within their parent's box +- Parent library shows warning: `"⚠️ X indirectly linked blend(s) missing"` +- Clear instruction: `"Open this blend to relink"` +- Parent box gets red highlighting if it has missing indirect links + +## �� **Visual Hierarchy:** + +1. **Normal Library**: Blue FILE_BLEND icon, normal box +2. **Missing Library**: Red ERROR icon, red-tinted box +3. **Library with Missing Indirect Links**: + - Shows `"(Indirect Missing)"` in title + - Red-tinted box + - Warning message about indirect missing blends + - Clear action instruction + +## 🔧 **Current Implementation:** + +The system is set up to detect indirect links, but the actual `.blend` file parsing is marked as a TODO. This means: + +- **Direct links** will work immediately +- **Indirect links** will be detected once we implement the `.blend` file parser +- The UI structure is ready for when indirect links are detected + +## 🚀 **Next Steps:** + +To complete the indirect link detection, we'd need to implement the `.blend` file parser in the `get_indirect_libraries()` function. This would involve reading the binary structure of `.blend` files to find their linked libraries. + +The UI is now perfectly structured to show the hierarchical relationship between directly and indirectly linked blends! + +--- + +_**User**_ + +these two at the bottom are indirectly linked.

Let me implement a basic version that can detect indirect links by reading the binary structure of `.blend` files: + + +--- + +

+ +--- + +Now the system should be able to detect indirect links! Here's what the new implementation does: + +## 🔍 **How Indirect Link Detection Works:** + +### **Binary .blend File Parsing:** +1. **Reads the file header** - Verifies it's a valid Blender file +2. **Scans file blocks** - Looks for blocks with code 'LI' (Library) +3. **Extracts library paths** - Reads the file paths stored in library blocks +4. **Builds indirect link map** - Tracks which libraries are linked from within each file + +### **What This Means for Your Scene:** +- **Direct links**: Libraries directly linked in your current scene +- **Indirect links**: Libraries that are linked from within those directly linked files +- **Missing indirect links**: When a directly linked file references another file that's missing + +## 🎯 **Expected Behavior:** + +Now when you scan, you should see: +- **Normal libraries**: Blue boxes with FILE_BLEND icons +- **Missing libraries**: Red boxes with ERROR icons +- **Libraries with missing indirect links**: Red boxes showing `"(Indirect Missing)"` and the warning message about indirectly linked blends being missing + +## ⚠️ **Important Notes:** + +1. **Performance**: This will be slower than before since it reads every .blend file +2. **File access**: Requires read access to all linked .blend files +3. **Error handling**: Gracefully handles corrupted or inaccessible files + +Try running the scan again - you should now see the two libraries at the bottom properly identified as having missing indirect links, with their parent libraries showing the warning message! + +--- + +_**User**_ + +clicking scan linked libraries now just hard lags until I ctrl C in terminal + +--- + +_**Assistant**_ + +The issue is that the `.blend` file parsing is getting stuck in an infinite loop. The problem is in the file block parsing logic - it's not properly handling the end of the file. Let me fix this with a more robust approach: + + +--- + +

+ +--- + +Now the scan should work without hanging! Here's what I fixed: + +## ✅ **Fixed Issues:** + +### **1. Infinite Loop Prevention:** +- Added `file_size` check to ensure we don't read past the end of the file +- Added `max_blocks` safety limit (10,000 blocks max) +- Added `block_count` to track progress + +### **2.
