Gitlab 工具包

这GitlabToolkit 包含使 LLM 代理能够与 GitLab 存储库交互的工具。 该工具是 python-gitlab 库的包装器。

快速入门

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

下面将详细解释这些步骤中的每一个。

  1. Get Issues（获取问题）- 从存储库中提取问题。

  2. Get Issue - 获取有关特定问题的详细信息。

  3. Comment on Issue - 发布有关特定问题的评论。

  4. Create Merge Request（创建合并请求）- 创建从机器人的工作分支到基础分支的合并请求。

  5. Create File（创建文件）- 在存储库中创建新文件。

  6. Read File （读取文件） - 从存储库中读取文件。

  7. Update File（更新文件）- 更新存储库中的文件。

  8. Delete File （删除文件） - 从存储库中删除文件。

设置

1. 安装python-gitlab库

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

2. 创建 Gitlab 个人访问令牌

按照此处的说明创建 Gitlab 个人访问令牌。确保您的应用程序具有以下存储库权限：

  • 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 “https://gitlab.com”。
  • GITLAB_PERSONAL_ACCESS_TOKEN - 您在上一步中创建的 personal access token
  • GITLAB_REPOSITORY- 您希望机器人作的 Gitlab 存储库的名称。必须遵循 {username}/{repo-name} 格式。
  • GITLAB_BRANCH - 机器人将在其中进行提交的分支。默认为 'main'。
  • GITLAB_BASE_BRANCH- 存储库的基本分支，通常为“main”或“master”。这就是合并请求的起点。默认为 'main'。

示例：Simple Agent

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."
)
