+ +--- + +Excellent! Now your addon has comprehensive debug output for indirect link detection. Here's what I've implemented: + +## 🔍 **Enhanced Indirect Link Detection:** + +### **1. Safe Binary Parsing:** +- **File Header Validation** - Checks if it's a valid Blender file +- **Size Limits** - Won't process files larger than 100MB +- **Block Limits** - Maximum 10,000 blocks to prevent infinite loops +- **Error Handling** - Comprehensive try-catch blocks + +### **2. Library Block Detection:** +- **LI Block Scanning** - Looks for 'LI' blocks that contain library paths +- **Path Extraction** - Parses the block data to find .blend file paths +- **Validation** - Ensures paths look like valid file paths + +### **3. Debug Output:** +- **File Analysis** - Shows what's happening during parsing +- **Block Counts** - Reports total blocks and LI blocks found +- **Indirect Libraries** - Lists each indirect library discovered +- **Scan Summary** - Shows final results + +## 🧪 **Testing the Enhanced Detection:** + +1. **Enable the addon** - It should now work without indentation errors +2. **Click "Scan Linked Assets"** - Watch the Blender console for debug output +3. **Check the console** - You'll see detailed information about: + - Which files are being analyzed + - How many LI blocks are found + - What indirect libraries are detected + - Final scan results + +## �� **Expected Output:** +``` +Starting to parse [filepath] for indirect links... +Valid Blender file header found +Pointer size: 8, Endian: < +File size: [size] bytes +Found LI block #1, size: [size] +Found indirect library: [path] +Total blocks processed: [count], LI blocks found: [count] +=== SCAN COMPLETE === +Total libraries found: [count] +Libraries with indirect missing: [count] +``` + +Now when you scan, you should see exactly what's happening with indirect link detection and why it might not be working as expected. The debug output will help us identify any remaining issues! + +--- + +_**User**_ + +Ok, let's reconsider. FMT is great for image textures. Let's do something like this for the linked library analysis. So first, it scans, we have this implemented already. Then, it shows which are missing and has a field where you can browse for missing files and add multiple fields like the "search path" part of FMT. These fields should be settable in the addon preferences. Then, once it searches those fields for those files and tries to relink them, if it fails with a "unable to relocate indirectly linked library" we THEN know which ones are indirectly linked. + +--- + +_**Assistant**_ + +Excellent idea! That's a much smarter approach than trying to parse .blend files. Using Blender's built-in relinking system will naturally reveal the indirect links when it fails with that specific error message. Let me implement this approach: + +## �� **New Strategy:** +1. **Scan** - Find all linked libraries (already implemented) +2. **Show missing** - Display which files are missing +3. **Search paths** - Multiple configurable search paths (addon preferences) +4. **Attempt relink** - Use Blender's native relinking +5. **Detect indirect** - When relinking fails with "unable to relocate indirectly linked library" + +Let me start by updating the addon preferences to include search paths: + + +--- + +

+ +--- + +Excellent! Now I have implemented the new approach for detecting indirect links. Let me summarize what we've built: + +## �� **New Dynamic Link Manager Approach:** + +### **1. Smart Indirect Link Detection:** +- **No more binary parsing** - Eliminates the risk of data loss +- **Uses Blender's native system** - Leverages built-in relinking functionality +- **Detects indirect links naturally** - When relinking fails with "unable to relocate indirectly linked library" + +### **2. Search Path Management (Addon Preferences):** +- **Configurable search paths** - Add/remove multiple directories to search +- **Persistent storage** - Settings saved between Blender sessions +- **File browser integration** - Easy path selection with folder picker + +### **3. Enhanced UI Features:** +- **Search Paths section** - Shows current paths and management buttons +- **Attempt Relink button** - Only appears when there are missing libraries +- **Missing count display** - Shows how many libraries need relinking +- **Indirect link warnings** - Automatically detected and displayed + +### **4. Workflow:** +1. **Scan** - Find all linked libraries (already working) +2. **Configure** - Add search paths in addon preferences +3. **Attempt Relink** - Click button to try relinking missing files +4. **Auto-detect** - Indirect links are automatically identified from error messages +5. **Display** - UI shows which libraries have indirect missing dependencies + +## �� **How to Use:** + +1. **Enable the addon** - Should work without indentation errors now +2. **Go to Preferences > Add-ons** - Find "Dynamic Link Manager" +3. **Add search paths** - Click "Add Search Path" and select directories +4. **Scan your scene** - Click "Scan Linked Assets" in the 3D View sidebar +5. **Attempt relink** - Click "Attempt Relink" to find missing files +6. **View results** - Indirect links will be automatically detected and highlighted + +This approach is much more robust and follows Blender's natural workflow for handling missing linked files. The indirect link detection happens automatically when the relinking process encounters the specific error message you mentioned! + +--- + +_**User**_ + + + +--- + +_**Assistant**_ + +I can see the issue! The error shows that `IntProperty` is not defined in the `operators.py` file.

FMT-Inspired Layout:** +- **Box-based sections** - Clear visual separation like FMT +- **Row alignment** - Consistent spacing and alignment +- **Icon integration** - Meaningful icons for different states +- **Status indicators** - Clear MISSING/INDIRECT/OK status display + +### **4. Enhanced User Experience:** +- **Selected item details** - Shows full information about the selected library +- **Smart button states** - Buttons adapt based on selection +- **Visual feedback** - Red tinting for missing/indirect libraries +- **Compact information** - Truncated paths with ellipsis for space efficiency + +## 🔄 **New Workflow:** + +1. **Scan** - Click "Scan Linked Assets" to find all linked libraries +2. **Browse** - Use the compact list view to see all libraries at a glance +3. **Select** - Click on any library in the list to see its details +4. **Act** - Use "Open Selected" to open the selected library +5. **Manage** - Configure search paths and attempt relinking + +The UI now follows FMT's proven design patterns while maintaining our focus on linked library management and indirect link detection.
