C1Logger

My Website: Corpi1.uk

C1Log is a modern, thread-safe, and highly configurable logging library for .NET applications.
It supports asynchronous logging, file rolling (by date and size), minimum log level filtering, syslog-style log levels (with shorthand), and custom log sinks for advanced scenarios.

Installation

To use this library, install it via NuGet in your project. You can do this by running the following command in the Package Manager Console:

Latest Version:

NuGet\Install-Package C1.Logger

Specific Version:

NuGet\Install-Package C1.Logger --Version x.x.x

Alternatively, search for "C1Log" in the NuGet Package Manager in Visual Studio and install it from there.

Usage

For a full usage guide, please refer to the Docs

Note:
C1Log is fully self-initializing. You do not need to call any initialization method.
If you want to customize configuration (log directory, minimum log level, formatter, etc.), set those properties before your first log call.

Log Levels:

• Emergency (emerg)
• Alert (alert)
• Critical (crit)
• Error (error)
• Warning (warn)
• Notice (notice)
• Informational (info)
• Debug (debug)

Basic Examples:

Default usage with default settings:

using C1Logger; 
C1Log.Info("Application started."); 
C1Log.Flush(); // Ensure all logs are written

Customizing the log directory, log level and format:

using C1Logger; 
C1Log.LogDirectory = @"C:\Logs"; // Specify your log directory 
C1Log.MinLogLevel = C1Log.LogLevel.Warning; // Set minimum log level to Warning 
C1Log.Formatter = (dt, lvl, msg) => $"[{lvl.ShortHand()}] {dt:HH:mm:ss} - {msg}"; // Custom log message to use shorthand
C1Log.Info("Application started."); 
C1Log.Error("An error occurred."); 
C1Log.Flush(); // Ensure all logs are written

Full API Example:

using System; 
using C1Logger;
public class MyCustomSink : C1Log.ILogSink {
    public C1Log.LogLevel MinLogLevel => C1Log.LogLevel.Notice; 
    public void Dispose() { } 
    public Task WriteAsync(string message, 
    C1Log.LogLevel level, IDictionary<string, object> context = null) {
        // Custom sink logic here 
        return Task.CompletedTask; 
        } 
    }
class Program { 
    static void Main() { 
        // Configure logger before first log
        C1Log.LogDirectory = @"C:\Logs"; 
        C1Log.MinLogLevel = C1Log.LogLevel.Notice; 
        C1Log.Formatter = (dt, lvl, msg) => $"[{lvl.ShortHand()}] {dt:HH:mm:ss} - {msg}"; 
        C1Log.AddSink(new MyCustomSink());
        // Subscribe to logging failures
        C1Log.OnLoggingFailure += ex => Console.Error.WriteLine($"Logging failed: {ex}");

        // Log messages
        C1Log.Info("Informational message.");
        C1Log.Warning("Warning message.");
        C1Log.Error("Error message.");
        C1Log.Exception(new Exception("Test exception"));
        C1Log.Flush(); // Ensure all logs are written
    }
}

Building

If you want to build the project yourself, follow these steps:

1. Install Visual Studio (Community Edition is sufficient).
   • Select the .NET desktop development workload during installation.
2. Clone the repository to your local machine using Git or download it as a ZIP file.
3. Open the folder in Visual Studio as a new project.
4. Build the project by selecting Build > Build Solution or pressing Ctrl + Shift + B.
   • This should install all required dependencies. If not, manually install them via Manage NuGet Packages.
5. Once the build completes, you can run it:
   1. From Visual Studio: Debug > Start Debugging or F5
   2. From the built executable in \bin\Debug\net8.0 (or Release for release builds).
