golang下在終端顯示字體顏色及閃爍、下划線效果的小工具

在終端下打印不同顏色的字體，具體說明見：http://blog.csdn.net/gxut555/article/details/7913591

自己用golang實現一個，除了在MAC下顯示不出效果來，其他端上還算正常了，效果所示：

 

 

代碼如下(見：https://github.com/liuyongshuai/goColorTerm)：

import (
	"testing"
	"fmt"
)

func TestCliColor(t *testing.T) {
	fmt.Println(Green("閃爍字體：Green", 1, 1))

	fmt.Println(Cyan("閃爍字體：Cyan", 1))
	fmt.Println(LightCyan("閃爍字體：LightCyan", 1))
