这块逻辑比较复杂，需要花点时间review。

This logic is relatively complex and will take some time to review.

@oldme-git 我在项目中执行了一下，遇到生成方法重复的问题。我把文件作为附件上传，你可以尝试一下，建议加上一个类似的单例在提交代码中。

单测已经加上了。生成文件的那一块也整理了一下，去掉了因为正则不准确而又多添加的矫正代码。另外，在生成文件的地方进行了两个优化：

• 使用协程
• 使用 bytes.Buffer 替代字符串拼接，以提高性能。

最终性能得到了约 30% 的提升，以下是对 3000 个文件，若干方法测试的结果，单位秒，测试环境：go1.22.1 windows11/i7-13700k/64G memory

正则

在测试中，大部分的时间都用来 gofmt 生成好的文件。如果想获得更好的性能，可以对 gofmt 这一步进行优化，不过当前，也足够使用了

@oldme-git I executed it in the project and encountered the problem of duplicate generation methods. I uploaded the file as an attachment. You can try it. It is recommended to add a similar singleton in the submission code.

Packaged logic minimum file: logic.zip

Single test has been added. The generated file has also been tidied up, and the correction code added due to inaccurate regular expressions has been removed. In addition, two optimizations have been made where the file is generated:

• Use coroutines
• Use bytes.Buffer instead of string concatenation to improve performance.

The final performance was improved by about 30%. The following are the results of testing 3000 files with several methods, unit seconds, test environment: go1.22.1 windows11/i7-13700k/64G memory

In testing, most of the time is spent generating good files with gofmt. If you want to get better performance, you can optimize the gofmt step, but currently, it is enough.
