build and run 合体技. 来自 Go编程语言群成员 四叶草 发的 gorun 代码.

package main

import (
	"log"
	"os"
	"os/exec"
	"path/filepath"
)

func main() {
	wd, _ := os.Getwd()
	fd := filepath.Base(wd)
	// cmd := exec.Command("go", "build", fd)
	cmd := exec.Command("go", "build")
	cmd.Stdout = os.Stdout
	cmd.Stderr = os.Stderr
	err := cmd.Run()
	if err != nil {
		log.Fatalf("error build %v", err)
	}

	err = cmd.Wait()

	cmd = exec.Command(fd)
	for i := 1; i < len(os.Args); i++ {
		cmd.Args = append(cmd.Args, os.Args[i])
	}
	cmd.Stderr = os.Stderr
	cmd.Stdout = os.Stdout
	cmd.Run()
	cmd.Wait()
