type DateParser

type DateParser interface {
	ParseTimestamp(log string) (time.Time, string, bool) // Parse timestamp should have the implementation for parsing the timestamp from a log line
}

func NewDayMonthParser

func NewDayMonthParser(datetimeRegex string, layout string, opts ...DayMonthOption) DateParser

type Dateformat

type Dateformat struct {
	DateRegex  string
	Layout     string
	DateSuffix string
}

type DayMonthOption

type DayMonthParser

type DayMonthParser struct {
	// contains filtered or unexported fields
}

DayMonthParser will parse a timestamp string without a year and timezone into a datetime given the regex and layout of the timestamp. It will also optionally strip the outer date and detect if the remaining text contains a valid date
