英文:
Can not call `vim` within go code
问题
我试图在Go程序中调用vim，代码类似于这样：
package main
import (
"fmt"
"os"
"os/exec"
)
func main() {
err := exec.Command("vim", "a.txt").Run()
if err != nil {
fmt.Println(err)
}
os.Exit(0)
}
我运行了go run mycode.go然后得到了：
exit status 1
我尝试了几种方法来成功实现这个，例如用Start()、Output()等替换Run()，但似乎都不起作用。最后，我想做的是调用vim并停止当前的Go程序。我只想看到vim出现，仅此而已。
英文:
I try to call vim within go program, which code similar to this:
package main
import (
"fmt"
"os"
"os/exec"
)
func main() {
err := exec.Command("vim", "a.txt").Run()
if err != nil {
fmt.Println(err)
}
os.Exit(0)
}
I ran go run mycode.go then got:
exit status 1
I have tried several ways to succeed this e.g. replace Run() by Start(), Output(), ..., but it seems not work. Finally, What I try to do is I try to call vim and stop my current go program. I just want to see vim appear, that's all.

为了使vim能够渲染其界面，您需要将标准输入/输出流附加到进程中：
package main
import (
"fmt"
"os"
"os/exec"
)
func main() {
cmd := exec.Command("vim", "a.txt")
cmd.Stdin = os.Stdin
cmd.Stdout = os.Stdout
cmd.Stderr = os.Stderr
err := cmd.Run()
if err != nil {
fmt.Println(err)
}
os.Exit(0)
}
不附加流类似于从shell中运行以下命令：
vim < /dev/null > /dev/null 2> /dev/null
英文:
In order for vim to render its interface, you need to attach the standard input/output streams to the process:
package main
import (
"fmt"
"os"
"os/exec"
)
func main() {
cmd := exec.Command("vim", "a.txt")
cmd.Stdin = os.Stdin
cmd.Stdout = os.Stdout
cmd.Stderr = os.Stderr
err := cmd.Run()
if err != nil {
fmt.Println(err)
}
os.Exit(0)
}
Not attaching the streams is similar to running the following command from your shell:
vim < /dev/null > /dev/null 2> /dev/null
