Golog

Golog is a wrapper around logrus which conforms to Finn's logging requirements.

Getting started

Golog can be dropped in place of Logrus and used in a very similar manner:

package main

import log "github.com/finn-no/golog"

func main() {
    log.Info("hello, golog!")
}

Using FIAAS_ENVIRONMENT

Golog looks for the environment variable FIAAS_ENVIRONMENT. If it is non empty, Golog will conform to all of Finn's logging expectations. If it is empty, a standard Logrus logger will be used.

Setting level

The logging level can be set much in the same way as in Logrus:

log.SetLevel("debug")

SetLevel returns an error which can be checked like so:

if err := log.SetLevel("debugg"); err != nil {
    log.Fatalf("setting logging level: %v", err)
}

Using the logger

When you call golog.Info("some message"), the message's calling file will be from the golog package itself, rather than the actual calling file. This behaviour can be mitigated by using the logger directly:

logger := log.Logger()
logger.Info("hello, golog!")

This is the same logrus.Logger used by golog internally.
