FieldsOrder []string
// TimestampFormat - default: time.StampMilli = "Jan _2 15:04:05.000"
TimestampFormat string
// HideKeys - show [fieldValue] instead of [fieldKey:fieldValue]
HideKeys bool
// NoColors - disable colors
NoColors bool
// NoFieldsColors - apply colors only to the level, default is level + fields
NoFieldsColors bool
// NoFieldsSpace - no space between fields
NoFieldsSpace bool
// ShowFullLevel - show a full level [WARNING] instead of [WARN]
ShowFullLevel bool
// NoUppercaseLevel - no upper case for level value
NoUppercaseLevel bool
// TrimMessages - trim whitespaces on messages

Usage
import (
nested "github.com/antonfisher/nested-logrus-formatter"
"github.com/sirupsen/logrus"
)
log := logrus.New()
log.SetFormatter(&nested.Formatter{
HideKeys: true,
FieldsOrder: []string{"component", "category"},
})
log.Info("just info message")
// Output: Jan _2 15:04:05.000 [INFO] just info message
log.WithField("component", "rest").Warn("warn message")
// Output: Jan _2 15:04:05.000 [WARN] [rest] warn message
