Termly

Terminal colorizer for .NET console apps

Termly provides an easy to use set of extension methods to display colorized text in the terminal. It doesn't support arbitrary colors, instead it reuses the same old ConsoleColor constants. The idea here is that you don't need to come up with your own unique color pallete to display textual data, you just continue using the colors the user already chose for their terminal. The colorization is achieved with the use of a small subset of ANSI escape codes.

Apps with Termly look great in Windows Terminal with your favorite color scheme.

Usage

You can start adding color to the console output with InColor method extension.

private static void HandleContextLog(object sender, LoggingEventArgs e)
{
    if (e.Kind > ChannelMessageKind.Trace)
    {
        Console.Error.WriteLine($"{e.Source.InColor(ConsoleColor.Gray)}: {e.RawMessage.InColor(ConsoleColor.DarkBlue)}");
    }
}

The extension methods Write and WriteLine are used to colorize interpolated strings.

Console.Out.WriteLine(ConsoleColor.DarkYellow, $"Parameters Count: {parameters.Statistics.ParametersCount}");

Background colors are supported too.

Console.Error.WriteLine("ALERT".InColor(foreground: ConsoleColor.Black, background: ConsoleColor.Red));
