Code examples

package main
 
import (
    "syscall"
)
 
var (
    kernel32    *syscall.LazyDLL  = syscall.NewLazyDLL(`kernel32.dll`)
    proc        *syscall.LazyProc = kernel32.NewProc(`SetConsoleTextAttribute`)
    CloseHandle *syscall.LazyProc = kernel32.NewProc(`CloseHandle`)
 
    // 给字体颜色对象赋值
    FontColor Color = Color{0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15}
)
 
type Color struct {
    black        int // 黑色
    blue         int // 蓝色
    green        int // 绿色
    cyan         int // 青色
    red          int // 红色
    purple       int // 紫色
    yellow       int // 黄色
    light_gray   int // 淡灰色（系统默认值）
    gray         int // 灰色
    light_blue   int // 亮蓝色
    light_green  int // 亮绿色
    light_cyan   int // 亮青色
    light_red    int // 亮红色
    light_purple int // 亮紫色
    light_yellow int // 亮黄色
    white        int // 白色
}
 
// 输出有颜色的字体
func ColorPrint(s string, i int) {
    handle, _, _ := proc.Call(uintptr(syscall.Stdout), uintptr(i))
    print(s)
    CloseHandle.Call(handle)
}
 
func main() {
    ColorPrint(`红色`, FontColor.red)
    ColorPrint(`蓝色`, FontColor.blue)
    ColorPrint(`白色`, FontColor.white)
}
