Default key names for the default fields

Types

type FieldMap

type FieldMap map[fieldKey]string

FieldMap allows customization of the key names for default fields.

type GlogFormatter

type GlogFormatter struct {
	// Set to true to bypass checking for a TTY before outputting colors.
	ForceColors bool

	// Force disabling colors.
	DisableColors bool

	// Force quoting of all values
	ForceQuote bool

	// DisableQuote disables quoting for all values.
	// DisableQuote will have a lower priority than ForceQuote.
	// If both of them are set to true, quote will be forced on all values.
	DisableQuote bool

	// Override coloring based on CLICOLOR and CLICOLOR_FORCE. - https://bixense.com/clicolors/
	EnvironmentOverrideColors bool

	// Disable timestamp logging. useful when output is redirected to logging
	// system that already adds timestamps.
	DisableTimestamp bool

	// Enable logging the full timestamp when a TTY is attached instead of just
	// the time passed since beginning of execution.
	FullTimestamp bool

	// TimestampFormat to use for display when a full timestamp is printed
	TimestampFormat string

	// The fields are sorted by default for a consistent output. For applications
	// that log extremely frequently and don't use the JSON formatter this may not
	// be desired.
	DisableSorting bool

	// The keys sorting function, when uninitialized it uses sort.Strings.
	SortingFunc func([]string)

	// Disables the truncation of the level text to 4 characters.
	DisableLevelTruncation bool

	// PadLevelText Adds padding the level text so that all the levels output at the same length
	// PadLevelText is a superset of the DisableLevelTruncation option
	PadLevelText bool

	// QuoteEmptyFields will wrap empty fields in quotes if true
	QuoteEmptyFields bool

	// FieldMap allows users to customize the names of keys for default fields.
	// As an example:
	// formatter := &TextFormatter{
	//     FieldMap: FieldMap{
	//         FieldKeyTime:  "@timestamp",
	//         FieldKeyLevel: "@level",
	//         FieldKeyMsg:   "@message"}}
	FieldMap FieldMap

	// CallerPrettyfier can be set by the user to modify the content
	// of the function and file keys in the data when ReportCaller is
	// activated. If any of the returned value is the empty string the
	// corresponding key will be removed from fields.
	CallerPrettyfier func(*runtime.Frame) (function string, file string)

	// Disables the glog style ：[IWEF]yyyymmdd hh:mm:ss.uuuuuu threadid file:line] msg msg...
	// replace with ：[IWEF] [yyyymmdd] [hh:mm:ss.uuuuuu] [threadid] [file:line] msg msg...
	//EnablePrettyLog   bool
	EnableGoroutineId bool
	// contains filtered or unexported fields
}

GlogFormatter formats logs into text

func (*GlogFormatter) Format

func (f *GlogFormatter) Format(entry *logrus.Entry) ([]byte, error)

Format renders a single log entry
