Go Basic Logger

A basic logger written in Go so simple it's impossible to miss it.

Log levels

Level	Alias	Description
DEBUG	DBG	Debug information useful when programming
NOTICE	NOT	Notice information useful when requesting logs for errors/bugs
INFO	INF	Standard classic log level, general information that narrates the program execution
WARNING	WRN	Warning messages for non-blocking things that go wrong
ERROR	ERR	Error messages for non-blocking things that go wrong
CRITICAL	CRT	Critical messages it's mandatory to pay attention to, may be still non-blocking
FATAL	FAT	Fatal messages about things for which the program execution cannot continue

Examples

General usage:

package main

import git.bjphoster.com/b.pedini/go-basic-logger

logger Logger

func main() {
    logLevel := "DEBUG"
    logger = *new(Logger)
    logger.Initialize(&logLevel)
    logger.Debug("Program execution started")

    ...

    if err != nil {
        logger.Fatal("Received error during operation X:", err)
    }
}

Getting the Logger level from an environment variable (called LOGLEVEL, not customizable (yet)):

...

func main() {
    logger = *new(Logger)
    logger.Initialize(nil)

    ...
}
