Quick Taste

uses
  LoggerPro.GlobalLogger;

begin
  Log.Info('Application started');
  Log.Debug('Processing item %d', [42], 'WORKER');
  Log.Error('Connection failed', 'DATABASE');
end.

One line of uses, and you're logging to rotating files. It's that simple.

Builder API (v2.0)

Log := LoggerProBuilder
  .WithDefaultTag('MYAPP')
  .WriteToFile
    .WithLogsFolder('logs')
    .Done
  .WriteToConsole.Done
  .WriteToHTTP
    .WithURL('https://logs.example.com/api')
    .Done
  .Build;

Structured Context Logging

Log.Info('Order completed', 'ORDERS', [
  LogParam.I('order_id', 12345),
  LogParam.S('customer', 'John Doe'),
  LogParam.F('total', 299.99)
]);
