log

log is an out-of-the-box logger, it wraps zap and makes it simpler to use.

Install

$ go get github.com/juan-chan/log@latest

Example

import "github.com/juan-chan/log"

log.Info("Hello, World!")
log.Warn("Hello, Warning!")
log.Error("nil pointer dereference", ErrorField(errors.New("NPE")))
log.Error("some error", ErrorStr(errors.New("what's wrong")))
log.Infof("Today is %s, so happy!", "Friday")
log.Debug("This log should not be displayed")
log.SetDebug()
log.Debug("This log should be displayed")
log.SetLevel(ErrorLevel)
log.Info("This log should not be displayed")
log.Warn("This log should not be displayed")

logger, _ := New(&Config{Encoding: "console"})
log.ReplaceLogger(logger)
log.SetLevel(InfoLevel)
log.Infof("What's your name? My name is %s", "Chan")
log.Error("illegal argument error", String("arg", "name"))

Sentry

log supports sentry by default, you just need to set an environment variable named: SENTRY_DSN and log will add a hook for it.
