Glog Verbosity Wrapper

This is a wrapper for glog that allows you to set verbosity levels.

The following verbosity levels are supported:

• 0 - Exit, Fatal, Error, Warning, Info
• 1 - Exit, Fatal, Error, Warning
• 2 - Exit, Fatal, Error
• 3 - Exit, Fatal
• 4 - Exit
• 5 - Disable all logging

To set the verbosity level, use the flag.Set function:

flag.Set("v", "0") // Exit, Fatal, Error, Warning, Info
flag.Set("v", "1") // Exit, Fatal, Error, Warning
flag.Set("v", "2") // Exit, Fatal, Error
flag.Set("v", "3") // Exit, Fatal
flag.Set("v", "4") // Exit
flag.Set("v", "5") // Disable all logging

Installation

go get github.com/blankalmasry/glog

Example Usage

package main

import (
    "github.com/blankalmasry/glog"
)

func main() {
    // Required by Glog 
    flag.Parse()
    
    // Set the verbosity level to 1 (Exit, Fatal, Error, Warning) or running the program with the -v flag
    flag.Set("v", "1")

    // Log a message at the "Error" level
    glog.Error("This is an error message")

    // Log a message at the "Warning" level
    glog.Warning("This is a warning message")

    // Log a message at the "Fatal" level
    glog.Fatal("This is a fatal message")

    // This message will not be logged since the verbosity level is set to 1
    glog.Info("This is an info message")
}
