Previously, script and style tags were only filtered during render,
but their text content (JavaScript code) was still in the DOM tree.
Now we skip these tags entirely during DOM tree construction,
resulting in much cleaner output for modern websites.
- Merge browser_v2 implementation into browser.cpp
- Remove deprecated files: browser_v2.cpp/h, main_v2.cpp, text_renderer.cpp/h
- Simplify CMakeLists.txt to build single 'tut' executable
- Remove test HTML files no longer needed
- Add stb_image.h for image support
- Add image data storage in DomNode for decoded images
- Collect image nodes in DocumentTree during parsing
- Download and decode images in browser_v2 before layout
- Render images as colored ASCII art using True Color
- Use stb_image for PNG/JPEG/GIF/BMP decoding (requires manual download)
- Fall back to placeholder for failed/missing images
Major features:
- New modular architecture with Terminal, FrameBuffer, Renderer layers
- True Color (24-bit) support with warm, eye-friendly color scheme
- Unicode support with proper CJK character width handling
- Differential rendering for improved performance
- Page caching (LRU, 20 pages, 5-minute expiry)
- Search functionality with highlighting (/, n/N)
- Form rendering (input, button, checkbox, radio, select)
- Image placeholder support ([alt text] or [Image: filename])
- Binary data download via fetch_binary()
- Loading state indicators
New files:
- src/browser_v2.cpp/h - Browser with new rendering system
- src/main_v2.cpp - Entry point for tut2
- src/render/* - Terminal, FrameBuffer, Renderer, Layout, Image modules
- src/utils/unicode.cpp/h - Unicode handling utilities
- tests/* - Test programs for each module
Build with: cmake --build build_v2
Run: ./build_v2/tut2 [URL]
Major improvements:
- Add proper DOM tree structure (dom_tree.cpp/h) with hierarchical node representation
- Refactor HTML parser to use DOM tree instead of flat ContentElement structure
- Enhance text renderer with improved inline content handling and UTF-8 support
- Improve browser interactive element tracking with byte-accurate positioning
- Add comprehensive HTML entity decoding (80+ named entities + numeric)
- Enhance form handling with better field tracking and submission
Code quality improvements:
- Fix all compiler warnings (unused parameters/variables)
- Clean build with zero warnings
- Better separation of concerns between parsing and rendering
Testing:
- Add test_table.html for table rendering verification
This change enables better handling of complex HTML structures while
maintaining the Unix philosophy of simplicity and focus.
