Constants ¶
const ( // Bits or'ed together to control what's printed. There is no control over the // order they appear (the order listed here) or the format they present (as // described in the comments). A colon appears after these items: // 2009/0123 01:23:23.123123 /a/b/c/d.go:23: message Ldate = 1 << iota // the date: 2009/0123 Ltime // the time: 01:23:23 Lmicroseconds // microsecond resolution: 01:23:23.123123. assumes Ltime. Llongfile // full file name and line number: /a/b/c/d.go:23 Lshortfile // final file name element and line number: d.go:23. overrides Llongfile Lmodule // module name Llevel // level: 0(Debug), 1(Info), 2(Warn), 3(Error), 4(Panic), 5(Fatal) LstdFlags = Ldate | Ltime // initial values for the standard logger Ldefault = Lmodule | Llevel | Lshortfile | LstdFlags )
These flags define which text to prefix to each log entry generated by the Logger.
const ( Ldebug = iota Linfo Lwarn Lerror Lpanic Lfatal )
Variables ¶
var Std = New(os.Stderr, "", Ldefault)
Functions ¶
func Fatal ¶
func Fatal(v ...interface{})
Fatal is equivalent to Print() followed by a call to os.Exit(1).
func Fatalf ¶
func Fatalf(format string, v ...interface{})
Fatalf is equivalent to Printf() followed by a call to os.Exit(1).
func Fatalln ¶
func Fatalln(v ...interface{})
Fatalln is equivalent to Println() followed by a call to os.Exit(1).
func GetOutputLevel ¶
func GetOutputLevel() int
func Panic ¶
func Panic(v ...interface{})
Panic is equivalent to Print() followed by a call to panic().
func Panicf ¶
func Panicf(format string, v ...interface{})
Panicf is equivalent to Printf() followed by a call to panic().
func Panicln ¶
func Panicln(v ...interface{})
Panicln is equivalent to Println() followed by a call to panic().
func Print ¶
func Print(v ...interface{})
Print calls Output to print to the standard logger. Arguments are handled in the manner of fmt.Print.
func Printf ¶
func Printf(format string, v ...interface{})
Printf calls Output to print to the standard logger. Arguments are handled in the manner of fmt.Printf.
func Println ¶
func Println(v ...interface{})
Println calls Output to print to the standard logger. Arguments are handled in the manner of fmt.Println.
func SetOutputLevel ¶
func SetOutputLevel(lvl int)
Types ¶
type Logger ¶
type Logger struct {
Level int
// contains filtered or unexported fields
}
A Logger represents an active logging object that generates lines of output to an io.Writer. Each logging operation makes a single call to the Writer's Write method. A Logger can be used simultaneously from multiple goroutines; it guarantees to serialize access to the Writer.
func New ¶
New creates a new Logger. The out variable sets the destination to which log data will be written. The prefix appears at the beginning of each generated log line. The flag argument defines the logging properties.
func (*Logger) Fatalln ¶
func (l *Logger) Fatalln(v ...interface{})
Fatalln is equivalent to l.Println() followed by a call to os.Exit(1).
func (*Logger) Output ¶
Output writes the output for a logging event. The string s contains the text to print after the prefix specified by the flags of the Logger. A newline is appended if the last character of s is not already a newline. Calldepth is used to recover the PC and is provided for generality, although at the moment on all pre-defined paths it will be 2.
func (*Logger) Panic ¶
func (l *Logger) Panic(v ...interface{})
Panic is equivalent to l.Print() followed by a call to panic().
func (*Logger) Panicln ¶
func (l *Logger) Panicln(v ...interface{})
Panicln is equivalent to l.Println() followed by a call to panic().
func (*Logger) Print ¶
func (l *Logger) Print(v ...interface{})
Print calls l.Output to print to the logger. Arguments are handled in the manner of fmt.Print.
func (*Logger) Printf ¶
Printf calls l.Output to print to the logger. Arguments are handled in the manner of fmt.Printf.
func (*Logger) Println ¶
func (l *Logger) Println(v ...interface{})
Println calls l.Output to print to the logger. Arguments are handled in the manner of fmt.Println.
func (*Logger) SetOutputLevel ¶
SetOutputLevel sets the output level for the logger.
