翻译规范

  1. 创建一个认领issue,认领标题中注明tip号和标题。不允许一人同时认领多个任务。翻译完一项任务后才能认领下一个任务。
  2. 任务请搜索 Phuong Le 的Twitter账号,找到对应的tip,然后翻译成中文。(可能有的tip作者已经删除,经咨询,作者反馈内容会有增删,所以如果某个tip不存在,请空一个,寻找下一个tip)
  3. fork 本项目,然后在 fork 后的项目中进行翻译认领的一个tip,翻译完成后提交pull request
  4. 任务请在一周内完成,未完成的任务将被释放,其他人可以认领。
  • 项目自动统计贡献者
  • 翻译请保持语句通顺,可以使用AI协助翻译,但是一定要避免生硬和机翻的感觉

**怎么提交Pull Request? **

如果大家以前没有提交过 Pull Request,可以探索下。 首先点击项目右上角的 Fork 按钮,将项目 Fork 到自己的仓库。 在github浏览你fork的项目,你会看到一个 "Create pull request" 按钮,点击它 填写相关的内容提交即可。 后续等待项目的维护者合并你的PR即可。

# Tip #76 函数调用的结果回传

>  原始链接:[Golang Tip #76: Result forwarding in function call](https://twitter.com/func25/status/1779128931586850890)
>

当我刚开始使用go语言的时候,我发现有一个概念比较棘手:函数调用结果的回传。

....
  • 在src下创建翻译文件: xxx.md, 内容模板如上
  • 图片放入 src/images 文件夹中
  • src/SUMMARY.md 文件中加入你翻译的一项
  • README 文件中翻译任务认领表格 填写你翻译的项目
