PyRappel is an interactive assembler with ptrace support - a Python version of the original rappel tool.

pip install pyrappel

git clone <repository-url>
cd pyrappelv2
pip install .

git clone <repository-url>
cd pyrappelv2
pip install -e .[dev]

After pip installation, PyRappel is automatically installed as a system-wide executable. You can run it from anywhere in your terminal:

pyrappel -h

The pyrappel command is automatically:

• Installed in your system PATH (e.g., /usr/local/bin/pyrappel or ~/.local/bin/pyrappel)
• Made executable
• Available from any directory

• -a, --arch: Target architecture (x86 or x64, default: x64)
• -s, --start-addr: Start virtual address for code execution (default: 0x400000)
• -A, --all-regs: Display all available registers (including FP/SSE)
• -v, --verbose: Enable verbose output

# Start with x64 architecture (default)
pyrappel

# Start with x86 architecture
pyrappel -a x86

# Start with custom start address
pyrappel -s 0x10000000

# Show all registers
pyrappel -A

• Python 3.11+
• Linux (ptrace support required)
• Dependencies are automatically installed via pip

The package uses modern Python packaging with pyproject.toml. For development:

pip install -e .[dev]

This is a Python reimplementation of the original C version: Rappel
