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 GitLab 个人访问令牌
  3. 设置环境变量
  4. 使用 toolkit.get_tools() 将工具传递给您的代理
下面将详细解释每个步骤。
  1. 获取问题 - 从仓库获取问题。
  2. 获取单个问题 - 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到基础分支创建合并请求。
  5. 创建文件 - 在仓库中创建新文件。
  6. 读取文件 - 从仓库读取文件。
  7. 更新文件 - 更新仓库中的文件。
  8. 删除文件 - 从仓库删除文件。

​
设置

​
1. 安装 python-gitlab 库

pip install -qU  python-gitlab langchain-community

​
2. 创建 GitLab 个人访问令牌

请在此处遵循说明 以创建 GitLab 个人访问令牌。确保您的应用具有以下仓库权限：
  • read_api
  • read_repository
  • write_repository

​
3. 设置环境变量

在初始化代理之前，需要设置以下环境变量：
  • GITLAB_URL - 托管 GitLab 的 URL。默认为 “gitlab.com”。
  • GITLAB_PERSONAL_ACCESS_TOKEN - 您在最后一步创建的個人访问令牌
  • GITLAB_REPOSITORY - 您希望机器人操作的 GitLab 仓库名称。必须遵循格式 {username}/{repo-name}。
  • GITLAB_BRANCH - 机器人进行提交的分支。默认为 ‘main’。
  • GITLAB_BASE_BRANCH - 您仓库的基础分支，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 create_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 = create_agent(
    model=llm,
    tools=toolkit.get_tools(),
    verbose=True,
)

agent.invoke(
    {
        "input": "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."
    }
)

> Entering new AgentExecutor chain...
 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
