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):

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)) }
