从Windows批处理文件中检测ANSI兼容控制台？ [英] Detect ANSI-compatible console from Windows batch file?

问题描述

Windows 10控制台主机 conhost.exe 具有对ANSI转义序列的本地支持，而较早的版本则不支持。如何从批处理文件中检测是否存在控制台ANSI支持？

Windows 10 console host, conhost.exe, has native support for ANSI escape sequences, older versions do not. How can one detect the presence or absence of console ANSI support from a batch file?

是否可以调用 GetConsoleMode 还是直接从批处理文件中调用其他Windows API？

Is it possible to call GetConsoleMode or other Windows API calls directly from a batch file?

推荐答案

最后一个问题的答案是：是，借助PowerShell代码。此批处理文件可以执行您的请求：

The answer to your last question is: Yes, with the aid of PowerShell code. This Batch file do what you requested:

@echo off
setlocal

set /A STD_OUTPUT_HANDLE=-11
set /A ENABLE_PROCESSED_OUTPUT=1, ENABLE_WRAP_AT_EOL_OUTPUT=2, ENABLE_VIRTUAL_TERMINAL_PROCESSING=4

PowerShell  ^
   $GetStdHandle = Add-Type 'A' -PassThru -MemberDefinition '  ^
      [DllImport(\"Kernel32.dll\")]  ^
      public static extern IntPtr GetStdHandle(int nStdHandle);  ^
   ';  ^
   $GetConsoleMode = Add-Type 'B' -PassThru -MemberDefinition '  ^
      [DllImport(\"Kernel32.dll\")]  ^
      public static extern bool GetConsoleMode(IntPtr hWnd, ref UInt32 lpMode);  ^
   ';  ^
   $StdoutHandle = $GetStdHandle::GetStdHandle(%STD_OUTPUT_HANDLE%);  ^
   $ConsoleMode = New-Object -TypeName UInt32;  ^
   $null = $GetConsoleMode::GetConsoleMode($StdoutHandle,[ref]$ConsoleMode);  ^
   Set-Content ConsoleMode.txt $ConsoleMode  ^
%End PowerShell%

set /P "ConsoleMode=" < ConsoleMode.txt
set /A "AnsiCompatible=ConsoleMode & ENABLE_VIRTUAL_TERMINAL_PROCESSING"
if %AnsiCompatible% neq 0 (
   echo The console is Ansi-compatible!
) else (
   echo Ansi codes not supported...
)

我编写了此类代码在Add-Type cmdlet的PowerShell帮助中阅读示例，并在这个问题。

I wrote this type of code reading the examples at the PowerShell help on Add-Type cmdlet and the info given in the accepted answer at this question.
