cpgclientlib 0.9.231

A client library for CPG servers

A Python client library for Joern Server

A library to script code analyzers based on code property graphs (e.g., Joern/Ocular) via Python.

Requirements

• Python 3 and Pip(we do not support Python 2.7) see (https://packaging.python.org/tutorials/installing-packages/)

Installation

To download and install the latest version, issue the following command:

pip install cpgclientlib

Usage

Assuming that joernd is running locally, the following short scripts creates a code property graph and runs a query to retrieve all methods in JSON format.

#!/usr/bin/env python3

from cpgclient.CpgClient import CpgClient

server = '127.0.0.1'
port = 8080
client = CpgClient(server, port)
client.create_cpg('/path/to/cpg')
methods = client.query('cpg.method.toJson')
print(methods)
