GitLab 工具包

The Gitlab 工具包包含使LLM代理能够与gitlab仓库进行交互的工具。The tool 是 python-gitlab 库的包装器。

快速开始​

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

这些步骤将在下面进行详细解释。

  1. 获取问题- 从仓库中检索问题。

  2. 获取问题- 获取特定问题的详细信息。

  3. 在问题上留言- 在特定的问题上发表评论。

  4. 创建合并请求- 从机器人的工作分支向基础分支创建一个合并请求。

  5. 创建文件- 在仓库中创建新文件。

  6. 读取文件- 从仓库中读取文件。

  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​

按照此处的说明 创建一个GitLab个人访问令牌。确保你的应用具有以下仓库权限：

  • read_api
  • read_repository
  • write_repository

3. 设置环境变量​

在初始化您的代理之前，需要设置以下环境变量：

  • GITLAB_URL - 托管的 GitLab 地址。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- 你要让机器人作用的GitLab仓库的名字。必须遵循{用户名}/{仓库名}的格式。
  • GITLAB分支- 机器人将在此分支进行提交。默认为'main'。
  • GITLAB_BASE_BRANCH- 你的仓库的基础分支，通常是'main'或'master'。合并请求将基于此分支。默认为'main'。

from langchain_openai import OpenAI

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."
)
