logger

Overview ¶

Package logger provides a leveled, concurrent-safe logging utility built on top of the standard library's log package. Logs are written to disk using rlog and can be filtered by level: debug, info, warn, error, or none.

The logger prefixes messages with the process ID and supports dynamic log level changes, log formatting customization, and safe shutdown via Close().

Usage:

package main

import "github.com/Data-Corruption/rlog/logger"

// Create a logger
logDir := "./logs"
l, err := logger.New(logDir, "debug")
if err != nil {
	log.Fatalf("Failed to create logger: %v", err)
}
defer l.Close() // Ensure logs are flushed

// Log using methods
l.Info("Application started")
l.Debugf("Configuration value: %s", "some_value")

// Log using context
ctx := context.Background()
ctx = logger.IntoContext(ctx, l) // Place logger into context
logger.Info(ctx, "Hello") // Uses logger placed into context
logger.Warn(ctx, "Warning message")
