DWARF Viewer

A powerful tool for viewing and analyzing DWARF debugging information from ELF executables. It provides both command-line and web interface for exploring debug information entries (DIEs).

Features

• Reads DWARF debugging information from ELF executables

  the fileparser could be extended to support Mach-O, PE, etc.

• Displays the DIEs and their Children recursively
• Displays the DIEs and their siblings recursively
• Supports filtering DIEs using regular expressions
• Interactive web interface for exploring DIEs
• Hierarchical navigation of DIE relationships
• Support for all DWARF tags and attributes

Requirements

• Go 1.21 or later
• ELF executable with DWARF debugging information

Installation

go install -v github.com/hitzhangjie/dwarfviewer@latest

or

git clone https://github.com/hitzhangjie/dwarfviewer
cd dwarfviewer
go install -v

Testing

Run the tests and learn how to use it before inspecting your own ELF file.

# Build the program
make

# Run tests
make test
make test2
make test3
make test4

Usage

Command Line Interface

# Build the program
go build

# View all DWARF information
./dwarfviewer -file <path-to-elf-file>

# Filter DIEs by name using regex
./dwarfviewer -file <path-to-elf-file> -pattern "main"

# Launch web interface
./dwarfviewer -file <path-to-elf-file> -webui

Web Interface

When launched with the -webui flag, the tool provides an interactive web interface at http://localhost:8080 with the following features:

• Hierarchical view of all DIEs
• Search functionality for filtering DIEs
• Detailed view of DIE attributes and values
• Navigation breadcrumbs for exploring DIE relationships
• Interactive tree view of DIE children
