Logr Build Status

Some different implementations of the go-logr/logr logging interface.

Currently there’s only a standard implementation (stdlogr) using fmt that prints logs to STDOUT in logfmt.

stdlogr

The stdlogr uses fmt to print logs to STDOUT in logfmt. Error logs get printed even if the InfoLogger is disabled.

Example:

package main

import (
  "errors"

  "actshad.dev/logr/stdlogr"
)

func main() {
  // Create new "foo" logger that's enabled and has a verbosity level of 1.
  logger := stdlogr.New("foo", true, 1)
  logger.Info("is this working?", "working", true)

  foobarLogger := logger.WithName("bar")
  err := errors.New("this is an error")
  foobarLogger.Error(err, "what about this logger?", "hello", "world!")

  logger.V(1).Info("verbosity 1 log")
  logger.V(2).Info("verbosity 2 log")
}

Output:

level=info ts=1534767423 name=foo msg="is this working?" working=true
level=error ts=1534767423 name=foo.bar msg="what about this logger?" hello=world! error="this is an error"
level=info ts=1534767423 name=foo msg="verbosity 1 log" v=1
