Types

type Brush

type Brush func(string) string

func NewBrush

func NewBrush(color string) Brush

type ConsoleWriter

type ConsoleWriter struct {
	Level      int  `json:"level"`
	Formatting bool `json:"formatting"`
	// contains filtered or unexported fields
}

ConsoleWriter implements LoggerInterface and writes messages to terminal.

func (*ConsoleWriter) Destroy

func (_ *ConsoleWriter) Destroy()

func (*ConsoleWriter) Flush

func (_ *ConsoleWriter) Flush()

func (*ConsoleWriter) Init

func (cw *ConsoleWriter) Init(config string) error

func (*ConsoleWriter) WriteMsg

func (cw *ConsoleWriter) WriteMsg(msg string, skip, level int) error

type FileLogWriter

type FileLogWriter struct {
	*log.Logger

	// The opened file
	Filename string `json:"filename"`

	Maxlines int `json:"maxlines"`

	// Rotate at size
	Maxsize int `json:"maxsize"`

	// Rotate daily
	Daily   bool  `json:"daily"`
	Maxdays int64 `json:"maxdays"`

	Rotate bool `json:"rotate"`

	Level int `json:"level"`
	// contains filtered or unexported fields
}

FileLogWriter implements LoggerInterface. It writes messages by lines limit, file size limit, or time frequency.

func (*FileLogWriter) Destroy

func (w *FileLogWriter) Destroy()

destroy file logger, close file writer.

func (*FileLogWriter) DoRotate

func (w *FileLogWriter) DoRotate() error

DoRotate means it need to write file in new file. new file name like xx.log.2013-01-01.2

func (*FileLogWriter) Flush

func (w *FileLogWriter) Flush()

flush file logger. there are no buffering messages in file logger in memory. flush file means sync file from disk.

func (*FileLogWriter) Init

func (w *FileLogWriter) Init(config string) error

Init file logger with json config. config like:

{
"filename":"log/gogs.log",
"maxlines":10000,
"maxsize":1<<30,
"daily":true,
"maxdays":15,
"rotate":true
}

func (*FileLogWriter) StartLogger

func (w *FileLogWriter) StartLogger() error

start file logger. create log file and set to locker-inside file writer.

func (*FileLogWriter) WriteMsg

func (w *FileLogWriter) WriteMsg(msg string, skip, level int) error

write logger message into file.

type LogLevel

type LogLevel int

type Logger
