Packages

Package	NuGet	Description
Bia.LogViewer.Core		Core abstractions: LogModel, ILogEntrySource, IClipboardService
Bia.LogViewer.Avalonia		Avalonia UserControl + LogViewerViewModel with filtering UI

All packages are cross-platform, trimmable and AOT/NativeAOT compatible.

Features

• Log level filtering — toggle Info, Warning, Error, Critical independently via bitmask
• Auto-scroll — automatically scrolls to the latest log entry
• Copy on select — optionally copies selected log message to clipboard
• Per-level counters — real-time count badges for each severity level
• Observable source — uses ObservableCollections for high-performance reactive updates

Usage

1. Implement the interfaces

// Provide log entries from your logging pipeline
public class MyLogSource : ILogEntrySource
{
    public IReadOnlyObservableList<LogModel>? Entries { get; }
}

// Platform clipboard integration
public class MyClipboard : IClipboardService
{
    public async Task CopyToClipboardAsync(string? text)
    {
        // Use Avalonia's clipboard API
    }
}

2. Create the ViewModel and bind it

var vm = new LogViewerViewModel(logSource, clipboardService);

3. Use the control in AXAML

<logViewer:LogViewerControl DataContext="{Binding LogViewerVm}" />
