Usage 🚀

Importing the Package 📦

First, import the package in your Go file:

import "github.com/catalystgo/logger/cli

Setting Log Level 📏

You can set the current log level using the SetLevel function. The available log levels are:

• LevelDebug
• LevelInfo
• LevelWarn
• LevelError
• LevelFatal

For example, to set the log level to LevelDebug:

log.SetLevel(log.LevelDebug)

Logging Messages 📝

You can log messages at different levels using the following functions:

• Debug(msg string)
• Debugf(msg string, args ...interface{})
• Info(msg string)
• Infof(msg string, args ...interface{})
• Warn(msg string)
• Warnf(msg string, args ...interface{})
• Error(msg string)
• Errorf(msg string, args ...interface{})
• Fatal(msg string)
• Fatalf(msg string, args ...interface{})

Each log level has its own prefix and color:

Examples 🚀

Here are some examples of how to use the logging functions:

log.SetLevel(log.LevelDebug)

log.Debug("This is a debug message")
log.Debugf("This is a debug message with a variable: %d", 42)

log.Info("This is an info message")
log.Infof("This is an info message with a variable: %d", 42)

log.Warn("This is a warning message")
log.Warnf("This is a warning message with a variable: %d", 42)

log.Error("This is an error message")
log.Errorf("This is an error message with a variable: %d", 42)

log.Fatal("This is a fatal message")
log.Fatalf("This is a fatal message with a variable: %d", 42)

// Panic functions can't be disabled by setting the log level to a higher value
// since they are meant to be used in critical situations where the application can't continue

log.Panic("This is a panic message")
log.Panicf("This is a panic message with a variable: %d", 42)
