"exit status 128" trying to create git branches from golang
问题
我正在尝试从Golang创建一个“特性分支”，以下代码无法正常工作：
reader := bufio.NewReader(os.Stdin)
fmt.Print(color.RedString("New feature description: "))
featureName, _ := reader.ReadString('\n')
featureName = strings.ReplaceAll(featureName, " ", "-")
featureBranchName := "feature/" + featureName
cmdStartBranch := "git"
arguments := []string{"checkout", "-b", featureBranchName}
if _, err := exec.Command(cmdStartBranch, arguments...).Output(); err != nil {
fmt.Println(color.RedString(err.Error()))
os.Exit(1)
}
但是，如果硬编码featureBranchName，它可以正常工作：
cmdStartBranch := "git"
arguments := []string{"checkout", "-b", "feature/ciaone-proprio"}
if _, err := exec.Command(cmdStartBranch, arguments...).Output(); err != nil {
fmt.Println(color.RedString(err.Error()))
os.Exit(1)
}
请注意，这是一段Golang代码，用于从标准输入读取新特性描述，并根据描述创建一个特性分支。第一个代码段中的问题可能是featureName中包含了换行符\n，导致分支名称无效。

I am trying to create a "feature branch" from golang. The following code is not working:
reader := bufio.NewReader(os.Stdin)
fmt.Print(color.RedString("New feature description: "))
featureName, _ := reader.ReadString('\n')
featureName = strings.ReplaceAll(featureName, " ", "-")
featureBranchName := "feature/" + featureName

arguments := []string{"checkout", "-b", featureBranchName}
if _, err := exec.Command(cmdStartBranch, arguments...).Output(); err != nil {
fmt.Println(color.RedString(err.Error()))
os.Exit(1)
}
But hardcoding featureBranchName it works:
cmdStartBranch := "git"
arguments := []string{"checkout", "-b", "feature/ciaone-proprio"}
if _, err := exec.Command(cmdStartBranch, arguments...).Output(); err != nil {
fmt.Println(color.RedString(err.Error()))
os.Exit(1)
}

得分: 1
[ReadString('\n')]返回分隔符'\n'，你需要将其移除。
featureName, err := reader.ReadString('\n')
if err == nil {
n := len(featureName)
featureName = featureName[:n-1]
}
...
英文:
[ReadString('\n')][1] returns the delimiter '\n', you need to remove it.
featureName, err := reader.ReadString('\n')
if err == nil {
n := len(featureName)
featureName = featureName[:n-1]
}
