The method of changing the echo color in go language: first open the corresponding go file; then assign a value to the font color object through the "FontColor Color=Color{}" method; finally use "func ColorPrint(s string, i int ){}" method to output colored fonts.
Environment of this article: Windows 7 system, Go1.11.2 version, this article is applicable to all brands of computers.
Recommended: "golang tutorial"
golang console color output (for windows)
Go language: console Output colored words
This method is only applicable to Windows systems
Application scenarios
Run logs that need to output a large amount of information (usually servers , Windows system)
Debugging interface of a certain type of client (usually games, especially those with third-party modules)
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)
}

Golang and Python: Understanding the DifferencesApr 18, 2025 am 12:21 AMThe main differences between Golang and Python are concurrency models, type systems, performance and execution speed. 1. Golang uses the CSP model, which is suitable for high concurrent tasks; Python relies on multi-threading and GIL, which is suitable for I/O-intensive tasks. 2. Golang is a static type, and Python is a dynamic type. 3. Golang compiled language execution speed is fast, and Python interpreted language development is fast.
Golang vs. C : Assessing the Speed DifferenceApr 18, 2025 am 12:20 AMGolang is usually slower than C, but Golang has more advantages in concurrent programming and development efficiency: 1) Golang's garbage collection and concurrency model makes it perform well in high concurrency scenarios; 2) C obtains higher performance through manual memory management and hardware optimization, but has higher development complexity.
Golang: A Key Language for Cloud Computing and DevOpsApr 18, 2025 am 12:18 AMGolang is widely used in cloud computing and DevOps, and its advantages lie in simplicity, efficiency and concurrent programming capabilities. 1) In cloud computing, Golang efficiently handles concurrent requests through goroutine and channel mechanisms. 2) In DevOps, Golang's fast compilation and cross-platform features make it the first choice for automation tools.
Golang and C : Understanding Execution EfficiencyApr 18, 2025 am 12:16 AMGolang and C each have their own advantages in performance efficiency. 1) Golang improves efficiency through goroutine and garbage collection, but may introduce pause time. 2) C realizes high performance through manual memory management and optimization, but developers need to deal with memory leaks and other issues. When choosing, you need to consider project requirements and team technology stack.
Golang vs. Python: Concurrency and MultithreadingApr 17, 2025 am 12:20 AMGolang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.
Golang and C : The Trade-offs in PerformanceApr 17, 2025 am 12:18 AMThe performance differences between Golang and C are mainly reflected in memory management, compilation optimization and runtime efficiency. 1) Golang's garbage collection mechanism is convenient but may affect performance, 2) C's manual memory management and compiler optimization are more efficient in recursive computing.
Golang vs. Python: Applications and Use CasesApr 17, 2025 am 12:17 AMChooseGolangforhighperformanceandconcurrency,idealforbackendservicesandnetworkprogramming;selectPythonforrapiddevelopment,datascience,andmachinelearningduetoitsversatilityandextensivelibraries.
Golang vs. Python: Key Differences and SimilaritiesApr 17, 2025 am 12:15 AMGolang and Python each have their own advantages: Golang is suitable for high performance and concurrent programming, while Python is suitable for data science and web development. Golang is known for its concurrency model and efficient performance, while Python is known for its concise syntax and rich library ecosystem.
