Constants ¶
const ( Ldate = 1 << iota // the date in the local time zone: 2009/01/23 Ltime // the time in the local time zone: 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 LUTC // if Ldate or Ltime is set, use UTC rather than the local time zone LstdFlags = Ldate | Ltime // initial values for the standard logger )
These flags define which text to prefix to each log entry generated by the Logger. Bits are 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). The prefix is followed by a colon only when Llongfile or Lshortfile is specified. For example, flags Ldate | Ltime (or LstdFlags) produce,
2009/01/23 01:23:23 message
while flags Ldate | Ltime | Lmicroseconds | Llongfile produce,
2009/01/23 01:23:23.123123 /a/b/c/d.go:23: message

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 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 the count of the number of frames to skip when computing the file name and line number if Llongfile or Lshortfile is set; a value of 1 will print the details for the caller of Output.
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.
Types ¶
type Logger ¶
type Logger struct {
// contains filtered or unexported fields
}
func New ¶
func New(projectID string, options ...LoggerOption) *Logger
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.
type LoggerOption ¶
type LoggerOption func(*LoggerOptions)
func WithContext ¶
func WithContext(ctx context.Context) LoggerOption
func WithDebug ¶
func WithDebug(debug bool) LoggerOption
func WithDefaultSeverity ¶
func WithDefaultSeverity(defaultSeverity logging.Severity) LoggerOption
func WithLocal ¶
func WithLocal(local bool) LoggerOption
func WithLogName ¶
func WithLogName(logname string) LoggerOption
func WithPrefix ¶
func WithPrefix(prefix string) LoggerOption
