Lunet.Extensions.Logging.SpectreConsole 1.1.0

Lunet.Extensions.Logging.SpectreConsole

A highly configurable Spectre.Console logger for Microsoft.Extensions.Logging.

Features

• Highly configurable
• Simple dependency to Microsoft.Extensions.Logging/7.0.0+ and Spectre.Console/0.47+
• Add log markup methods (e.g LogInformationMarkup, LogWarningMarkup...) that can take additional Spectre.Console renderable objects.
  • Compatible with other loggers. Ansi colors will be removed from output.
• Compatible with netstandard2.0+

Usage

On a logger factory configuration, you can simply configure Spectre console via the extension method configure.AddSpectreConsole()

Example 1

using Lunet.Extensions.Logging.SpectreConsole;
using Microsoft.Extensions.Logging;

// Example1: default layout (Similar to SimpleConsole)
using (var factory = LoggerFactory.Create(configure => configure.AddSpectreConsole()))
{
    var logger = factory.CreateLogger("SampleCategory");
    logger.LogInformationMarkup("Hello with [red]SpectreConsole[/]");
    logger.LogWarning("Hello without markup");
}

It will generate the following log:

Example 2

using Lunet.Extensions.Logging.SpectreConsole;
using Microsoft.Extensions.Logging;

// Example2: Don't add a new line, include timestamp
using (var factory = LoggerFactory.Create(configure =>
           {
               configure.AddSpectreConsole(new SpectreConsoleLoggerOptions()
               {
                   IncludeNewLineBeforeMessage = false,
                   IncludeTimestamp = true,
               });
           }
       ))
{
    var logger = factory.CreateLogger("SampleCategory");
    logger.LogInformationMarkup(new EventId(1), "Hello from [red]SpectreConsole[/]");
    logger.LogWarning(new EventId(2), "Hello without markup");
}

It will generate the following log:

Example 3

using Lunet.Extensions.Logging.SpectreConsole;
using Microsoft.Extensions.Logging;
using Spectre.Console;

// Example3: Don't add a new line, include timestamp, log a table
using (var factory = LoggerFactory.Create(configure =>
           {
               configure.AddSpectreConsole(new SpectreConsoleLoggerOptions()
               {
                   IncludeNewLineBeforeMessage = false,
                   IncludeTimestamp = true,
               });
           }
       ))
{

    var table = new Table();
    table.AddColumn("Name");
    table.AddColumn("Spectre?");
    table.AddRow("Microsoft.Extensions.Logging.Console", "⛔");
    table.AddRow("Lunet.Extensions.Logging.SpectreConsole", "✅");
    
    var logger = factory.CreateLogger("SampleCategory");
    logger.LogInformationMarkup(new EventId(1), "Hello from [red]SpectreConsole[/] with a table:", table);
    logger.LogWarning(new EventId(2), "Hello without markup");
}

It will generate the following log:
