从零搭建基于 AI GitHub 分析平台 (11) 基于commit diff 生成 commit 的总结

效果：

执行语句 bun run src/lib/gpt.ts :

- Set `randomOption` default value to `1` in the examination page.
- Add `zod` schema validation and new hooks for exam records and questions.
- Replace `useStartWCDialog` with `useExamDialog` for handling exam dialogs.
- Add logic to handle wrong question collections and create new exam records.
- Include `questionNum` in the API response for questions of a repository.
- Replace `thumbUrl` with `isWrongCollection` in the repositories API response.
- Reorganize imports and adjust button layout in the new exam dialog component.
- Filter repositories to hide items with `isWrongCollection` set to `1`.

我拿了一个比较复杂的代码提交，总结的比较到位。

编写 AI 调用函数

添加 src/lib/gpt.ts:

import OpenAI  from "openai";

const openai = new OpenAI({
  baseURL: 'https://api.deepseek.com',
  apiKey: process.env.OPENAI_API_KEY,
});

export const strict_output = async( 
  diff: string,
  model: string = "deepseek-chat",
  temperature: number = 1,
) => {

  let user_prompt = `You are expert programmer. and you are trying to summary a git diff 
Reminders about the git diff format:
For every file, there are a few metadata lines, like (for example):
\`\`\`
diff --git a/lib/index.js b/lib/index.js
index aadf691..bfef603 100644
--- a/lib/index.js
+++ b/lib/index.js
\`\`\`
This means that \`lib/index.js\` was modified in this commit. Note that this is only an example.
Then there is a specifier of the lines that were modified.
A line starting with "+" means it was added.
A line starting with "-" means that line was deleted.
A line that starts with neither "+" nor "-" is code given for context and better understanding.
It is not part of the diff.
After the git diff of the first file, there will be an empty line, and then the git diff of the next file.

EXAMPLE SUMMARY COMMENTS:
\`\`\`
- Increase the number of returned recordings from 10 to 100
- Correct a typo in the GitHub Action name
- Relocate the octokit initialization to a separate file
- Implement an OpenAI API endpoint for completions
- Reduce the numeric tolerance in test files
- Add 2 tests for the inclusive string split function
\`\`\`

Do not include the file name as another part of the comment.
Do not use the characters "[" or "]" in the summary.
Write every summary comment in a new line.
Comments should be in a bullet point list, each line starting with a "-".
The summary should not include comments copied from the code.
The output should be easily readable. When in doubt, write less comments and not more. Do not output comments that simply repeat the contents of the file.
Readability is top priority. Write only the most important comments about the diff.

Please summarise the following diff file: \n\n ${diff}`

  // Use OpenAI to get a response  
  const response = await openai.chat.completions.create({
    temperature: temperature,
    model: model,
    messages: [
      { role: "user", content: user_prompt },
    ],
  });

  // let res: string = response.choices[0].message?.content?.replace(/'/g, '"') ?? "";
  let res: string;
  if (response && response.choices && response.choices[0] && response.choices[0].message) {
    res= response.choices[0].message.content?.replace(/'/g, '"') ?? "";
  } else {
    res = "";
    console.error("Response is undefined or does not contain choices");
  }   

  // ensure that we don't replace away apostrophes in text
  res = res.replace(/(\w)"(\w)/g, "$1'$2");

  return res;
}
