### Quick Start Guide

Source: https://github.com/lazygophers/log/blob/master/README.md

A basic example demonstrating how to set the log level and log messages at different severity levels using the lazygophers/log library.

```go
package main

import "github.com/lazygophers/log"

func main() {
    // 设置日志级别
    log.SetLevel(log.InfoLevel)
    
    // 记录日志
    log.Info("Application started")
    log.Debug("This is debug message") // 不会被输出
    log.Warn("Something might be wrong")
    
    // 格式化日志
    log.Infof("User %s logged in", "Alice")
    
    // 记录错误
    log.Error("Failed to connect database")
}
```

### API Reference

Source: https://github.com/lazygophers/log/blob/master/README.md

Comprehensive API documentation for the lazygophers/log library, detailing core structures, logging methods, and configuration options.

```APIDOC
Core Structures:
  log: The main logger instance.
    SetLevel(level Level): Sets the global logging level. Only messages at or above this level will be output.
    SetOutput(writers ...io.Writer): Configures the output destinations for log messages. Accepts multiple io.Writer interfaces.
    Clone(): Creates a new logger instance that is a copy of the current one, allowing for independent configuration.
    SetCallerDepth(depth int): Adjusts the depth at which the caller information (file, line, function) is captured. Useful for wrapping loggers.

Logging Methods (by Level):
  Trace/Tracef(msg string, args ...interface{}): Logs a message at the TRACE level. Tracef supports formatted strings.
  Debug/Debugf(msg string, args ...interface{}): Logs a message at the DEBUG level. Debugf supports formatted strings.
  Info/Infof(msg string, args ...interface{}): Logs a message at the INFO level. Infof supports formatted strings.
  Warn/Warnf(msg string, args ...interface{}): Logs a message at the WARN level. Warnf supports formatted strings.
  Error/Errorf(msg string, args ...interface{}): Logs a message at the ERROR level. Errorf supports formatted strings.
  Fatal/Fatalf(msg string, args ...interface{}): Logs a message at the FATAL level and then calls os.Exit(1). Fatalf supports formatted strings.
  Panic/Panicf(msg string, args ...interface{}): Logs a message at the PANIC level and then triggers a panic. Panicf supports formatted strings.

Configuration Methods:
  SetPrefixMsg(): Enables setting a custom prefix for log messages.
  SetSuffixMsg(): Enables setting a custom suffix for log messages.
  ParsingAndEscaping(): Toggles the parsing and escaping of log message content.
  Caller(): Toggles the inclusion of caller information (file, line, function name) in log output.
