nested-logrus-formatter

Human-readable log formatter, converts logrus fields to a nested structure:

Configuration:

type Formatter struct {
    FieldsOrder     []string // by default fields are sorted alphabetically
    TimestampFormat string   // by default time.StampMilli = "Jan _2 15:04:05.000" is used
    HideKeys        bool     // to show only [fieldValue] instead of [fieldKey:fieldValue]
    NoColors        bool     // to disable all colors
    NoFieldsColors  bool     // to disable colors only on fields and keep levels colored
    ShowFullLevel   bool     // to show full level (e.g. [WARNING] instead of [WARN])
    TrimMessages    bool     // to trim whitespace 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
