Golang的fmt.Print(“ \ 033c”)和fmt.Print(“ \ x1bc”)无法清除屏幕(ANSI Escape代码不起作用)如何解决?

Whenever I run fmt.Print("\033c") in golang on windows cmd it does not clear screen but prints c whenever I do console.log("\033c") in javascript it works fine.

According to the following links this should have worked: https://en.wikipedia.org/wiki/ANSI_escape_code#Windows

https://docs.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences#samples

I have tried logging it in javascript and it works fine I also tried adding a character to the end which printed c and changing it to \x1bc which also just printed: c

the following all prints: c on windows cmd


func main() {
  fmt.Print("\033c")
  fmt.Print("\033c
")
  fmt.Print("\x1bc")
  fmt.Print("\x1bc
")
  fmt.Println("\033c")
  fmt.Println("\x1bc")
}

I expected that it would just clear the screen as in javascript but for some reason it doesn't

To clarify I am talking about that the ANSI escape code is not working.

    The problem was that windows needs the ENABLE_VIRTUAL_TERMINAL_PROCESSING(0x0004) console flag I fixed it by using the following code to add the flag to the console:

    package main
    
    // #include "Windows.h"
    import "C"
    import "fmt"
    
    func main() {
        // Needed for getting handle and getting current console mode
        var mode C.DWORD
        handle := C.GetStdHandle(C.STD_OUTPUT_HANDLE)
        C.GetConsoleMode(handle, &mode)
    
        // Enable Virtual Terminal Processing by adding the flag to the current mode
        C.SetConsoleMode(handle, mode|0x0004)
        fmt.Print("\033c")
    }
    

    SetConsoleMode

    ===EDIT===

    Like Matmarbon mentioned in the comments // #include "Windows.h" line is nessecary and you need to have an gcc installed
