Gitlab 工具包

Gitlab 工具包包含使 LLM 代理能够与 gitlab 仓库交互的工具。 该工具是 python-gitlab 库的封装。

快速开始​

  1. 安装 python-gitlab 库
  2. 创建一个Gitlab个人访问令牌
  3. 设置您的环境变量
  4. 使用toolkit.get_tools()将工具传递给您的代理

以下将详细解释这些步骤中的每一个。

  1. 获取问题- 从仓库中获取问题。

  2. 获取问题- 获取特定问题的详细信息。

  3. 评论问题- 在特定问题上发布评论。

  4. 创建合并请求- 从机器人的工作分支创建一个合并请求到基础分支。

  5. 创建文件- 在仓库中创建一个新文件。

  6. 读取文件- 从仓库中读取文件。

  7. 更新文件- 更新仓库中的一个文件。

  8. 删除文件- 从仓库中删除一个文件。

设置​

1. 安装 python-gitlab 库​

%pip install --upgrade --quiet  python-gitlab langchain-community

2. 创建一个Gitlab个人访问令牌​

按照这里的指示创建一个Gitlab个人访问令牌。确保你的应用程序具有以下仓库权限：

  • read_api
  • 读取仓库
  • write_repository

3. 设置环境变量​

在初始化您的代理之前，需要设置以下环境变量：

  • GITLAB_URL - 托管Gitlab的URL。默认为"https://gitlab.com"。
  • GITLAB_PERSONAL_ACCESS_TOKEN - 你在上一步创建的个人访问令牌
  • GITLAB_REPOSITORY - 您希望机器人操作的Gitlab仓库的名称。必须遵循格式 {用户名}/{仓库名称}。
  • GITLAB_BRANCH - 机器人将提交的分支。默认为 'main'。
  • GITLAB_BASE_BRANCH - 你的仓库的基础分支，通常是 'main' 或 'master'。这是合并请求的基础。默认为 'main'。

示例：简单代理​

import os

from langchain.agents import AgentType, initialize_agent
from langchain_community.agent_toolkits.gitlab.toolkit import GitLabToolkit
from langchain_community.utilities.gitlab import GitLabAPIWrapper
from langchain_openai import OpenAI
# Set your environment variables using os.environ
os.environ["GITLAB_URL"] = "https://gitlab.example.org"
os.environ["GITLAB_PERSONAL_ACCESS_TOKEN"] = ""
os.environ["GITLAB_REPOSITORY"] = "username/repo-name"
os.environ["GITLAB_BRANCH"] = "bot-branch-name"
os.environ["GITLAB_BASE_BRANCH"] = "main"

# This example also requires an OpenAI API key
os.environ["OPENAI_API_KEY"] = ""
llm = OpenAI(temperature=0)
gitlab = GitLabAPIWrapper()
toolkit = GitLabToolkit.from_gitlab_api_wrapper(gitlab)
agent = initialize_agent(
    toolkit.get_tools(), llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True
)
agent.run(
    "You have the software engineering capabilities of a Google Principle engineer. You are tasked with completing issues on a gitlab repository. Please look at the open issues and complete them by creating merge requests that solve the issues."
)

 I need to look at the open issues and figure out how to solve them.
Action: Get Issues
Action Input: N/A
Observation: Found 1 issues:
[{'title': 'Add tic-tac-toe game', 'number': 15}]
Thought: I need to look at the details of this issue to figure out how to solve it.
Action: Get Issue
Action Input: 15
Observation: {"title": "Add tic-tac-toe game", "body": "Create a tic-tac-toe game using HTML, CSS, and JavaScript. Create a new file called game.html and store the code there.", "comments": "[]"}
Thought: I need to create the game.html file and add the code.
Action: Create File
Action Input: game.html
