This package provides an integrated tool for generating and executing C/C++ code snippets externally in Langchain. Allows Langchain users to specify the desired C++ standard version and set optional CPU time limits for code execution. Provides an interface with subprocess to run the generated C/C++ code.

pip3 install cpp-langchain

• C/C++ Code Generation and Execution: Generate and execute C/C++ code snippets to provide answers.
• Version Selection: Specify the desired C++ standard version (e.g., c++11, c++14, c++17, c++20).
• CPU Time Limits: Set optional CPU time limits for code execution to prevent long-running processes.

This tool can execute arbitrary code on the host machine. Use with caution and only if you fully understand the security risks associated with subprocess execution.

• Default Safety: The allow_dangerous_code option is set to False by default to prevent unauthorized code execution.
• Risk Acceptance: If you choose to set allow_dangerous_code to True, you acknowledge and accept the potential risks of executing malicious code.

Below is a simple script to use CppSubprocessTool with Langchain.

For more advanced usages please check example notebook.

import os os.environ["OPENAI_API_KEY"] = "" from cpp_langchain import CppSubprocessTool tools = [CppSubprocessTool(allow_dangerous_code=True)] from langchain_openai import ChatOpenAI from langchain.agents import AgentExecutor, create_tool_calling_agent from langchain_core.prompts import ChatPromptTemplate llm = ChatOpenAI(model="gpt-4") prompt = ChatPromptTemplate.from_messages( [ ( "system", "You are a helpful coding assistant.
