Functions

func GuessParser

func GuessParser(line string) (Parser, *Log, error)

GuessParser guesses the parser from line, uses default parsers for each format

Types

type Apache

type Apache struct {
	// If set to true, ignores non-fatal errors while parsing line,
	// which may leave some fields empty or invalid.
	Loose bool
}

Log is the struct stored parsed result of single line of accesslog

func Parse

func Parse(line string) (*Log, error)

Parse log line using default parsers

type Parser

type Parser interface {
	Parse(string) (*Log, error)
}

Parser is the interface for accesslog

type Parsers
