# 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)

    ...
}
```
