Color Console Output

[reepblue]

This would be nice to identify what messages are from Print, DebugLog, Warn, etc. It'll help make errors pop out too. 

 

Here's how I'd do it. Works on all platforms.

	enum PrintColor
	{
		PRINT_COLOR_NORM = 0,
		PRINT_COLOR_MAGENTA,
		PRINT_COLOR_GREEN,
		PRINT_COLOR_BLUE,
		PRINT_COLOR_YELLOW,
		PRINT_COLOR_RED
	};	

	void PrintWString(const std::wstring& message, PrintColor printcolor)
	{
#if defined (_WIN32)
		HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

		// Apply a log tag
		switch (printcolor)
		{
		case PRINT_COLOR_MAGENTA:
			SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_BLUE | FOREGROUND_INTENSITY);
			break;

		case PRINT_COLOR_GREEN:
			SetConsoleTextAttribute(hConsole, FOREGROUND_GREEN | FOREGROUND_INTENSITY);
			break;

		case PRINT_COLOR_BLUE:
			SetConsoleTextAttribute(hConsole, FOREGROUND_BLUE | FOREGROUND_INTENSITY);
			break;

		case PRINT_COLOR_YELLOW:
			SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_INTENSITY);
			break;

		case PRINT_COLOR_RED:
			SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_INTENSITY);
			break;

		default:
			SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE);
			break;
		}

		std::wcout << message << std::endl;
		SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE);
#else
		static const std::wstring ColorRed(L"\033[0;31m");
		static const std::wstring ColorYellow(L"\033[1;33m");
		static const std::wstring ColorGreen(L"\033[1;32m");
		static const std::wstring ColorCyan(L"\033[0;36m");
		static const std::wstring ColorMagenta(L"\033[0;35m");
		static const std::wstring ColorDefault(L"\033[0m");

		switch (printcolor)
		{
		case PRINT_COLOR_MAGENTA:
			std::wcout << ColorMagenta;
			break;

		case PRINT_COLOR_GREEN:
			std::wcout << ColorGreen;
			break;

		case PRINT_COLOR_BLUE:
			std::wcout << ColorCyan;
			break;

		case PRINT_COLOR_YELLOW:
			std::wcout << ColorYellow;
			break;

		case PRINT_COLOR_RED:
			std::wcout << ColorRed;
			break;

		default:
			std::wcout << ColorDefault;
			break;
		}

		std::wcout << message << ColorDefault << std::endl;
#endif
	}

I don't think this changes the color in Visual Studio's output window, but I'll be someone who will still be forcing the console window for my debug builds.

How about this?

#include "UltraEngine.h"

using namespace UltraEngine;

bool PrintColorHook(const Event& e, shared_ptr<Object> extra)
{
    //https://learn.microsoft.com/en-us/windows/console/getstdhandle#handle-disposal
    HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);

    if (e.text.Left(8) == "Warning:")
    {
        SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_INTENSITY);
    }
    else if (e.text.Left(6) == "Error:")
    {
        SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_INTENSITY);
    }
    else
    {
        SetConsoleTextAttribute(hConsole, FOREGROUND_RED | FOREGROUND_GREEN | FOREGROUND_BLUE);
    }
    return true;
}

int main(int argc, const char* argv[])
{
    ListenEvent(EVENT_PRINT, NULL, PrintColorHook);

    Print("Here is a normal text message.");
    Print("Warning: Here is a warning.");
    Print("Here is a normal text message.");
    Print("Error: Here is an error.");
    Print("Here is a normal text message.");

    return 0;
}

Idk why I didn't think of that before. I guess that could work too. I ended up making a wrapper function but I wanna revisit that to make sure I'm not losing anything.
