golang下在终端显示字体颜色及闪烁、下划线效果的小工具

在终端下打印不同颜色的字体,具体说明见:http://blog.csdn.net/gxut555/article/details/7913591

自己用golang实现一个,除了在MAC下显示不出效果来,其他端上还算正常了,效果所示:

 

 

代码如下(见:https://github.com/liuyongshuai/goColorTerm):

//绿色字体,modifier里,第一个控制闪烁,第二个控制下划线
func Green(str string, modifier ...interface{}) string {
	return cliColorRender(str, 32, 0, modifier...)
}

//淡绿
func LightGreen(str string, modifier ...interface{}) string {
	return cliColorRender(str, 32, 1, modifier...)
}

//青色/蓝绿色

}

	//闪烁效果
	isBlink := 0
	if len(extraArgs) > 0 {
		isBlink, _ = MakeItemElem(extraArgs[0]).ToInt()
	}
	//下划线效果
	isUnderLine := 0
	if len(extraArgs) > 1 {

	var mo []string
	if isBlink > 0 {

	}
	if weight > 0 {
		mo = append(mo, fmt.Sprintf("%d", weight))
	}
	if len(mo) <= 0 {
		mo = append(mo, "0")
	}
	return fmt.Sprintf("\033[%s;%dm"+str+"\033[0m", strings.Join(mo, ";"), color)
}

测试效果:

package tofuutils

import (
	"testing"
	"fmt"
)

func TestCliColor(t *testing.T) {
	fmt.Println(Green("闪烁字体:Green", 1, 1))
	fmt.Println(LightGreen("闪烁字体:LightGreen", 1))
	fmt.Println(Cyan("闪烁字体:Cyan", 1))
	fmt.Println(LightCyan("闪烁字体:LightCyan", 1))
	fmt.Println(Red("闪烁字体:Red", 1))
	fmt.Println(LightRed("闪烁字体:LightRed", 1))
	fmt.Println(Yellow("闪烁字体:Yellow", 1))
	fmt.Println(Black("闪烁字体:Black", 1))
	fmt.Println(DarkGray("闪烁字体:DarkGray", 1))
	fmt.Println(LightGray("闪烁字体:LightGray", 1))
	fmt.Println(White("闪烁字体:White", 1))
	fmt.Println(Blue("闪烁字体:Blue", 1))
	fmt.Println(LightBlue("闪烁字体:LightBlue", 1))
	fmt.Println(Purple("闪烁字体:Purple", 1))
	fmt.Println(LightPurple("闪烁字体:LightPurple", 1))
	fmt.Println(Brown("闪烁字体:Brown", 1))
	fmt.Println(Green("字体:Green"))
	fmt.Println(LightGreen("字体:LightGreen"))
	fmt.Println(Cyan("字体:Cyan"))
	fmt.Println(LightCyan("字体:LightCyan"))
	fmt.Println(Red("字体:Red"))
	fmt.Println(LightRed("字体:LightRed"))
	fmt.Println(Yellow("字体:Yellow"))
	fmt.Println(Black("字体:Black"))
	fmt.Println(DarkGray("字体:DarkGray"))
	fmt.Println(LightGray("字体:LightGray"))
	fmt.Println(White("字体:White"))
	fmt.Println(Blue("字体:Blue"))
	fmt.Println(LightBlue("字体:LightBlue"))
	fmt.Println(Purple("字体:Purple"))
	fmt.Println(LightPurple("字体:LightPurple"))
	fmt.Println(Brown("字体:Brown"))
	fmt.Println(Blue("字体:Blue", 1, 1))
