问题


I am making a tutorial program for a friend of mine using batching programming. I would like to know if it is possible if there is code I can write in the file that will display the current color code.

Example being the color is currently set to 0A and I want be displayed on the line saying:

echo The color is currently set to 0A.

I want my file to read the code that is set to and display it to help them remember what changes they have made as this is an example program for color codes in the command prompt/batch.

Thank you for your help!

It is easy to make your own command to do this. Copy both below text files into GetConsoleColour.bat and GetConsoleColour.vb in the same folder. Double click the batch file and it will create GetConsoleColour.exe.

PS Colour is spelt right for my culture. As I'm writing it I don't see any need to use American spelling which in programming you usually have to do.

See https://docs.microsoft.com/en-us/windows/console/getconsolescreenbufferinfo

GetConsoleColour.exe prints the current console colour in hex and returns an errorlevel with the value

To use

C:\PathToFile\GetConsoleColour

I have a program here that sets text color line by line. It is the only technique that will work on all Windows computers.

Command Prompt Scripting: Problem with multiple colors in a batch file.

Also a similar program saying how many processes are in this console window - ListConsole.exe list the processes in the current console and returns an errorlevel saying how many . https://winsourcecode.blogspot.com/2019/05/listconsoleexe-list-processes-in.html

REM GetConsoleColour.bat
REM This file compiles GetConsoleColour.vb to GetConsoleColour.exe
REM GetConsoleColour.exe prints the current console colour and returns an errorlevel with the value
"C:\Windows\Microsoft.NET\Framework\v4.0.30319\vbc.exe" /target:exe /out:"%~dp0\GetConsoleColour.exe" "%~dp0\GetConsoleColour.vb" 
pause

Note: There is only 4 lines of code here. The rest is just information the program needs to do those 4 lines. In a big program they would be hidden away in a separate file.

As already indicated in another answer, you can use powershell from your batch-file to show you the current color sequence:

@(Set/P "=The color is currently set to "<NUL&For /F %%# In ('^""%__AppDir__%WindowsPowerShell\v1.0\powershell.exe" -NoP "$Console=(Get-Host).UI.RawUI;Switch($Console.BackgroundColor,$Console.ForegroundColor){'Black'{'0'}'DarkBlue'{'1'}'DarkGreen'{'2'}'DarkCyan'{'3'}'DarkRed'{'4'}'DarkMagenta'{'5'}'DarkYellow'{'6'}'Gray'{'7'}'DarkGray'{'8'}'Blue'{'9'}'Green'{'A'}'Cyan'{'B'}'Red'{'C'}'Magenta'{'D'}'Yellow'{'E'}'White'{'F'}}" 2^>NUL^"')Do @Set/P=%%#<NUL)&Echo(&Pause

You should also be able to do it from the command-prompt thus:

(Set/P "=The color is currently set to "<NUL&For /F %# In ('^""%__AppDir__%WindowsPowerShell\v1.0\powershell.exe" -NoP "$Console=(Get-Host).UI.RawUI;Switch($Console.BackgroundColor,$Console.ForegroundColor){'Black'{'0'}'DarkBlue'{'1'}'DarkGreen'{'2'}'DarkCyan'{'3'}'DarkRed'{'4'}'DarkMagenta'{'5'}'DarkYellow'{'6'}'Gray'{'7'}'DarkGray'{'8'}'Blue'{'9'}'Green'{'A'}'Cyan'{'B'}'Red'{'C'}'Magenta'{'D'}'Yellow'{'E'}'White'{'F'}}" 2^>NUL^"')Do @Set/P=%#<NUL)&Echo(

By making a compromise and using setlocal EnableDelayedExpansion, you can do so using the following:

@ECHO OFF

Setlocal enableDelayedExpansion

Set "Color=Color 02" && !color!

ECHO Color is currently %color%

pause

The downside of this approach being changing console Color becomes a 2 Step process (depending on how your displaying information).

You also, can try get some help with $Host.UI.RawUI in powershell?

@echo off && setlocal EnableDelayedExpansion

@set "_color=!_color!"5 DarkMagenta","6 DarkYellow","7 Gray","8 DarkGray","
      set "_color=!_color!"9 Blue","A Green","B Cyan","C Red","D Magenta","

if not "!_FB!"=="!_Hex:~1,1!" ( set "_FB=!_Hex:~0,1!!_FB!" && set "_L= !_Hex:~2!!_L!" )))
