Detailed Description

Console logging component with colored output.

CConsoleLogComp outputs log messages to the console (std::wcout) with platform-specific colored output based on message severity. This makes it easy to visually distinguish between info, warnings, and errors when running applications from the command line.

The component uses CStreamLogCompBase for message formatting and filtering, and adds color support for both Windows (via Windows console API) and Unix-like systems (via ANSI escape codes).

Color Scheme

Info/None: Default console color (typically white/gray)
Warning: Yellow/amber text
Error: Red text
Critical: Bright red text

Platform Support

Windows: Uses SetConsoleTextAttribute API
Unix/Linux/macOS: Uses ANSI escape codes (when terminal supports them)

Usage Example: // Create console logger

istd::TSharedInterfacePtr<ilog::CConsoleLogComp> console(

new ilog::CConsoleLogComp);

// Configure formatting

// In .acc:

// MinCategory: 1 (info and above)

// UseCategory: true (show "Warning:", "Error:")

// UseCode: true (show message IDs)

// UseTimeStamp: false (no timestamps)

// Send messages

console->AddMessage(istd::TSharedInterfacePtr<ilog::CMessage>(

new ilog::CMessage(istd::IInformationProvider::IC_INFO,

1001, "Application started", "Main")));

console->AddMessage(istd::TSharedInterfacePtr<ilog::CMessage>(

new ilog::CMessage(istd::IInformationProvider::IC_ERROR,

5001, "Connection failed", "Network")));

// Console output:

// Info (1001): Application started - Main

// Error (5001): Connection failed - Network [in red]
