✒️ golog

golog is a simple, fast and easy-to-use level-based logger written entirely in GoLang.

🥇 Features

• Focus on high performance and agile perspective of things
• Easy API and a default package-level instance, i.e golog#Fatalf/Errorf/Warnf/Infof/Debugf
• Fully compatible with the standard library
• Thanks to the pio library it supports any type of structure, gives you the ability to Hijack and Handle or Intercept the on-going logs too
• Set or even Add unlimited number of output targets, io.Writer
• Scan from any io.Reader and log to the defined output target(s)
• Levels such as fatal,error, warn, info, debug, or disable
• Beautiful (customizable) colors for leveled logs, automatically omit colors when output does not support colors (i.e files)
• Incredible high-performant, 3 times faster than your favourite logger
• Never-Panics

Navigate through _examples and integrations to learn if that fair solution suits your needs.

🚀 Installation

The only requirement is the Go Programming Language*.

$ go get github.com/kataras/golog

golog is fairly built on top of the pio library, it has no more external dependencies.

package main

import (
    "github.com/kataras/golog"
)

func main() {
    // Default Output is `os.Stdout`,
    // but you can change it:
    // golog.SetOutput(os.Stderr)

    // Time Format defaults to: "2006/01/02 15:04"
    // you can change it to something else or disable it with:
    golog.SetTimeFormat("")

    // Level defaults to "info",
    // but you can change it:
    golog.SetLevel("debug")

    golog.Println("This is a raw message, no levels, no colors.")
    golog.Info("This is an info message, with colors (if the output is terminal)")
    golog.Warn("This is a warning message")
    golog.Error("This is an error message")
    golog.Debug("This is a debug message")
    golog.Fatal("Fatal will exit no matter what, but it will also print the log message if logger's Level is >=FatalLevel")
}
