以前是 merge 了 branch 以后，自己删除，试着用 github 的新功能 github actions 进行自动化。

方法这里介绍的很详细

https://help.github.com/en/articles/creating-a-workflow-with-github-actions#creating-a-workflow-using-the-file-editor

这次添加下面的文件然后 push 到 github 就行了，完成以后 actions 页面可以进行查看。

文件内容

# .github/main.workflow

workflow "on pull request merge, delete the branch" {
  on = "pull_request"
  resolves = ["branch cleanup"]
}

action "branch cleanup" {
  uses = "jessfraz/branch-cleanup-action@master"
  secrets = ["GITHUB_TOKEN"]
}

然后 merge 一个 branch 以后，就会自动删除它。

不知道大家怎么玩的 github actions
