PvWay.LoggerService.Console.nc8 1.0.3

pvWay ConsoleLoggerService for dotNet Core 8

Description

This nuget implements the ILoggerService as a simple stdout console using Console.WriteLine statements.

The output is colored depending on the severity.

Severity enum

public enum SeverityEnu
{
    Ok,         // "O" Green
    Trace,      // "T" Gray
    Debug,      // "D" White
    Info,       // "I" DarkCyan
    Warning,    // "W" DarkYellow
    Error,      // "E" DarkRed
    Fatal       // "F" Red
}

Methods

All methods include both a synchronous and an asynchronous signature.

The class also implement the ILogger interface (microsoft.logging)

See here after the main methods:

void Log(
    string message,
    SeverityEnu severity = SeverityEnu.Debug,
    [CallerMemberName] string memberName = "",
    [CallerFilePath] string filePath = "",
    [CallerLineNumber] int lineNumber = -1);

Task LogAsync(
    string message,
    SeverityEnu severity = SeverityEnu.Debug,
    [CallerMemberName] string memberName = "",
    [CallerFilePath] string filePath = "",
    [CallerLineNumber] int lineNumber = -1);
        
void Log(
    IEnumerable<string> messages,
    SeverityEnu severity,
    [CallerMemberName] string memberName = "",
    [CallerFilePath] string filePath = "",
    [CallerLineNumber] int lineNumber = -1);

Task LogAsync(
    IEnumerable<string> messages,
    SeverityEnu severity,
    [CallerMemberName] string memberName = "",
    [CallerFilePath] string filePath = "",
    [CallerLineNumber] int lineNumber = -1);

void Log(
    Exception e,
    SeverityEnu severity = SeverityEnu.Fatal,
    [CallerMemberName] string memberName = "",
    [CallerFilePath] string filePath = "",
    [CallerLineNumber] int lineNumber = -1);

Task LogAsync(
    Exception e,
    SeverityEnu severity = SeverityEnu.Fatal,
    [CallerMemberName] string memberName = "",
    [CallerFilePath] string filePath = "",
    [CallerLineNumber] int lineNumber = -1);

void Log(
    IMethodResult result,
    string? topic,
    [CallerMemberName] string memberName = "",
    [CallerFilePath] string filePath = "",
    [CallerLineNumber] int lineNumber = -1);

Task LogAsync(
    IMethodResult result,
    string? topic,
    [CallerMemberName] string memberName = "",
    [CallerFilePath] string filePath = "",
    [CallerLineNumber] int lineNumber = -1);

Injection

The AddPvWayConsoleLoggerService method extends the IServiceCollection

The default lifetime is Scoped and the default minimum log level is Trace... i.e. logging everything

    public static void AddPvWayConsoleLoggerService(
        this IServiceCollection services,
        SeverityEnu minLogLevel = SeverityEnu.Trace,
        ServiceLifetime lifetime = ServiceLifetime.Scoped)
    {
        services.TryAddSingleton<ILoggerServiceConfig>(_ =>
            new LoggerServiceConfig(minLogLevel));
        
        services.AddSingleton<
            ILoggerServiceFactory<IConsoleLoggerService>,
            ConsoleLoggerServiceFactory>();

        services.AddSingleton(
            typeof(IConsoleLoggerService<>),
            typeof(ConsoleLoggerService<>));

        var sd = new ServiceDescriptor(
            typeof(ILoggerService), 
            typeof(ConsoleLoggerService),
            lifetime);
        services.Add(sd);
        
        var sd2 = new ServiceDescriptor(
            typeof(IConsoleLoggerService),
            typeof(ConsoleLoggerService),
            lifetime);
        services.Add(sd2);
    }

Static factories

The PvWayConsoleLogger static class also exposes two public Create methods enabling to factor the service from your own code

    public static IConsoleLoggerService Create(
        SeverityEnu minLogLevel = SeverityEnu.Trace)
    {
        return new ConsoleLoggerService(minLogLevel);
    }

    public static IConsoleLoggerService<T> Create<T>(
        SeverityEnu minLogLevel = SeverityEnu.Trace)
    {
        return new ConsoleLoggerService<T>(minLogLevel);
    }

Usage

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using PvWay.LoggerService.Abstractions.nc8;
using PvWay.LoggerService.Console.nc8;

Console.WriteLine("Hello, ConsoleLoggerService");
Console.WriteLine();

var services = new ServiceCollection();
services.AddPvWayConsoleLoggerService();
var sp = services.BuildServiceProvider();
var ls = sp.GetService<ILoggerService>()!;

ls.Log("This is a trace test log message", SeverityEnu.Trace);
ls.Log("This is a debug test log message");
ls.Log("This is an info test log message", SeverityEnu.Info);
ls.Log("This is a warning test log message", SeverityEnu.Warning);
ls.Log("This is an error test log message", SeverityEnu.Error);
ls.Log("This is a fatal test log message", SeverityEnu.Fatal);

ls.Log(LogLevel.Trace, "MsLog trace");

Happy coding
