如何在windows上使用java中的vt100转义码

https://docs.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences 把它翻译成Java。

这会使用一些对kernel32.dll的调用,因此我必须合并Java本机访问(JNA)。要运行它,您需要下载 jna-*version*.jar jna-platform-*version*.jar 从 https://github.com/java-native-access/jna#download 并将它们包含在你的项目中。

import com.sun.jna.*;
import com.sun.jna.platform.win32.WinDef.*;
import com.sun.jna.platform.win32.WinNT.HANDLE;

在程序开始时,您可以通过运行以下代码来启用vt100:

if(System.getProperty("os.name").startsWith("Windows"))
{
    // Set output mode to handle virtual terminal sequences
    Function GetStdHandleFunc = Function.getFunction("kernel32", "GetStdHandle");
    DWORD STD_OUTPUT_HANDLE = new DWORD(-11);
    HANDLE hOut = (HANDLE)GetStdHandleFunc.invoke(HANDLE.class, new Object[]{STD_OUTPUT_HANDLE});

    DWORDByReference p_dwMode = new DWORDByReference(new DWORD(0));
    Function GetConsoleModeFunc = Function.getFunction("kernel32", "GetConsoleMode");
    GetConsoleModeFunc.invoke(BOOL.class, new Object[]{hOut, p_dwMode});

    int ENABLE_VIRTUAL_TERMINAL_PROCESSING = 4;
    DWORD dwMode = p_dwMode.getValue();
    dwMode.setValue(dwMode.intValue() | ENABLE_VIRTUAL_TERMINAL_PROCESSING);
    Function SetConsoleModeFunc = Function.getFunction("kernel32", "SetConsoleMode");
    SetConsoleModeFunc.invoke(BOOL.class, new Object[]{hOut, dwMode});
}

从那时起

System.out.print("\u001b[31mHello, World!");
