如何在 Go 中编写一个程序，在编辑器中打开文件并在退出时恢复该程序？

我需要在 Go 中编写一个函数，在 Vim 或 Nano 中打开文件，然后在退出编辑器时恢复 Go 程序。

这就是我所拥有的：

func OpenEd(page string) error {
    pagePath := GetPath(page, DEBUG)
    ed := "/usr/bin/nano"
    cmd := exec.Command(ed, pagePath)
    err := cmd.Start()
    cmd.Wait()

    return err
}

它运行时没有错误，但什么也不做。我认为我必须分叉主进程才能正确运行 exec 功能，就像 C 中典型的那样。但我对此进行了研究，我认为 Go 中不是这样处理的。但我不确定，Go 对我来说相当陌生。

C 中的这段代码完全按照我希望 Go 代码运行的方式运行：

void openEd(void)
{
    int rc;

    char *args[] = {"test.txt", NULL};

    rc = fork();
    if (rc == 0) {
        execvp("nano", args);
    }
    wait(&rc);
}

How do I get this Go function to run like this C function?

I need to write a function in Go that opens a file in Vim or Nano and then upon exiting the editor, have the Go program resume.

Here's what I have:

func OpenEd(page string) error {
    pagePath := GetPath(page, DEBUG)
    ed := "/usr/bin/nano"
    cmd := exec.Command(ed, pagePath)
    err := cmd.Start()
    cmd.Wait()

    return err
}

It runs with no error but does nothing. I was thinking that I would have had to fork the main process to run the exec functionality properly like what is typical in C. But I looked into that and I don't think that's how it's handled in Go. But I'm not sure, Go is fairly new to me.

This code in C runs exactly how I want the Go code to run:

void openEd(void)
{
    int rc;

    char *args[] = {"test.txt", NULL};

    rc = fork();
    if (rc == 0) {
        execvp("nano", args);
    }
    wait(&rc);
}

How do I get this Go function to run like this C function?
