logger

Overview ¶

Package logger provides structured logging configuration for clibot.

This package initializes and configures logrus for structured logging with support for:

• Multiple log levels (debug, info, warn, error)
• File output with automatic log rotation
• Console output with color formatting
• JSON format for production environments

Configuration ¶

Logging behavior is configured through the Config struct:

• Level: Minimum log level to capture (default: "info")
• File: Path to log file (optional)
• MaxSize: Maximum size of single log file in MB (default: 100)
• MaxBackups: Maximum number of old log files to keep (default: 5)
• MaxAge: Maximum number of days to retain old logs (default: 30)
• Compress: Whether to compress rotated logs (default: true)
• EnableStdout: Also output to stdout (default: true)

Usage ¶

// Initialize logger with configuration
config := logger.Config{
    Level: "debug",
    File: "/var/log/clibot/app.log",
    EnableStdout: true,
}
if err := logger.InitLogger(config); err != nil {
    log.Fatal(err)
}

// Use structured logging
logger.WithFields(logrus.Fields{
    "user": "alice",
    "action": "login",
}).Info("User logged in")
