DWARF Explorer is a cross-platform GUI utility for visualizing DWARF debugging information in executable files. Built on PyQt6, pyelftools, and filebytes, it allows users to open ELF, Mach-O, PE, WASM, and ar files to browse their DWARF debug information tree. The application provides views for DIEs (Debugging Information Entries), attributes, references, and includes specialized tools for analyzing locals at addresses, function maps, data sections, frame information, and unwind data. The architecture follows a modular design with clear separation between the GUI layer (PyQt6-based interface in __main__.py and ui.py) and the DWARF analysis logic. Core functionality includes parsing various binary formats via formats.py, building and navigating the DIE tree through tree.py and die.py, and performing specialized analyses using utilities in dwarfutil.py, locs.py, and other modules. The application supports features like following DIE references, searching by conditions, highlighting DIEs, and exporting C skeletons. Key strengths include robust error handling with crash reporting, support for multiple binary formats and DWARF versions (including experimental v1 support), and thoughtful UI design with keyboard navigation, bookmarking, and detailed views. The code demonstrates good practices in separating concerns, with reusable components like the Mach-O unwind parser that could be extracted for use in other projects.
