LogC

A common and universal logging interface that every package in the simple frameworks org uses.

Adapters to common logging libraries are provided so whatever logging library that you decide to use can be supported.

type Logger interface {
	Trace(args ...interface{})
	Debug(args ...interface{})
	Info(args ...interface{})
	Warn(args ...interface{})
	Error(args ...interface{})
	WithField(key string, value interface{}) Logger
	WithFields(fields map[string]interface{}) Logger
	WithError(err error) Logger
}

Logrus example

An outgoing adapter is used to send log messages. Here we use Logrus.

log = logc.NewLogrus(logrus.New())

log.Trace("some Trace log")
log.Debug("some Debug log")
log.Info("some Info log")
log.Warn("some Warn log")
log.Error("some Error log")


log.WithField("RequestID",1234).Trace("some Trace log")


log.WithFields(map[string]interface{}{
  "RequestID":  1234,
  "Name":       "SomeName",
}).Info("some Info log")


someError := errors.New("an error occurred")
log.WithError(someError).Error("some Error log")

Gorm adapter

An incoming adapter is used to collect log messages. Here we are collecting logs from Gorm

log = logc.NewLogrus(logrus.New())

log.Info("connecting to db - started")

db, err0 := gorm.Open(sqlite.Open("file::memory:"), &gorm.Config{
	Logger: logging.NewGormLogger(log),
})

log.Info("connecting to db - completed")

log.Info("running db auto migration - started")

db.AutoMigrate(&User{})

log.Info("running db auto migration - completed")

user := User{Name: "shmc", Age: 18, Birthday: time.Now()}
result := db.Create(&user)

Currently only logrus is supported but more packages are planned.
