pypcode
=======
[![pypi](https://img.shields.io/pypi/v/pypcode)](https://pypi.org/project/pypcode/)

Machine code disassembly and IR translation library for Python using the
excellent [SLEIGH](https://ghidra.re/courses/languages/html/sleigh.html)
library from the [Ghidra](https://ghidra-sre.org/) framework (version 10.2.2).

This library was created primarily for use with [angr](http://angr.io), which
provides analyses and symbolic execution of p-code.

Quick Start
-----------
This package can be installed on Linux, macOS, and Windows platforms for recent
(3.8+) versions of both CPython and PyPy. Wheels are provided for several
configurations. You can install the latest release from PyPI using `pip`:

```bash
pip install pypcode
```

You can also install the very latest development version from this repository
using `pip`:

```bash
pip install --user https://github.com/angr/pypcode/archive/refs/heads/master.zip
```

You can now invoke the `pypcode` module from command line to translate supported
machine code to P-code from command line. Run `python -m pypcode --help` for
usage information. See module source (`__main__.py`) for examples of using
pypcode as a library.

Example
-------

```
$ python -m pypcode -b x86:LE:64:default test-x64.bin
