# angr-data — Data files (function and type prototype definitions) for angr, released as a separate package so they do not bloat every angr release

License: permissive · Maintenance: active · Downloads: 92.9K/mo

## What it is and what it does

angr-data is a data-only package that bundles function and type prototype definitions needed by the angr binary analysis framework. It provides a simple API—`get_path()`—to locate bundled data files by category and name, returning absolute paths for direct use. The package exists to keep angr releases lean by separating frequently-changing data from the main framework code.

The package is versioned independently from angr and released only when data files change. Each angr release pins a compatible angr-data version, ensuring that users get the right data definitions for their angr version. It has no runtime dependencies and supports Python 3.12 and later.

Use it for:

- Resolve function and type prototype definitions when using angr for binary analysis without needing to manage separate data files.
- Access platform-specific procedure definitions (e.g., win32) during static or dynamic analysis workflows.
- Retrieve Rust type database files for analyzing Rust-compiled binaries with version-specific metadata.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides bundled data files—function and type prototype definitions—for the angr binary analysis framework, accessible via a simple path lookup API.

Yes, if you use angr for binary analysis. It is a required data dependency for angr, has low install friction, no external dependencies, and is actively maintained. The permissive BSD-2-Clause license poses no restrictions.

## Install

pip install angr-data
uv add angr-data
poetry add angr-data

## Installing angr-data

Before you install: Low friction install with no runtime dependencies. Actively maintained as of 2026-06-24 with recent release activity.

License in practice: BSD-2-Clause permissive license allows commercial and private use with minimal restrictions.

Quickstart:

import angr_data

# Get absolute path to bundled data
path = angr_data.get_path("procedures", "definitions", "win32")
path2 = angr_data.get_path("rust", "analyses", "type_db", "1.39.0.json")

Requires Python 3.12 or later.

Verify before relying:

- Whether data files are updated frequently enough to warrant tracking angr-data versions separately from angr releases.
- Coverage and completeness of prototype definitions for different platforms and Rust versions.
