Functions ¶
func Criticalfln ¶
func Criticalfln(format string, v ...interface{})
func Fatal ¶
func Fatal(v ...interface{})
Fatal prints the logging content with [FATA] header and newline, then exit the current process.
func Fatalf ¶
func Fatalf(format string, v ...interface{})
Fatalf prints the logging content with [FATA] header and custom format, then exit the current process.
func Fatalfln ¶
func Fatalfln(format string, v ...interface{})
Fatalf prints the logging content with [FATA] header, custom format and newline, then exit the current process.
func GetBacktrace ¶ added in v1.5.0
GetBacktrace returns the caller backtrace content, the optional parameter <skip> specify the skipped backtrace offset from the end point.
func GetPath ¶
func GetPath() string
GetPath returns the logging directory path for file logging. It returns empty string if no directory path set.
func GetWriter ¶
GetWriter returns the customized writer object, which implements the io.Writer interface. It returns nil if no customized writer set.
func PrintBacktrace ¶ added in v1.5.0
func PrintBacktrace(skip ...int)
PrintBacktrace prints the caller backtrace, the optional parameter <skip> specify the skipped backtrace offset from the end point.
func SetBacktrace ¶ added in v1.5.0
func SetBacktrace(enabled bool)
SetBacktrace enables/disables the backtrace feature in failure logging outputs.
func SetDebug ¶
func SetDebug(debug bool)
SetDebug enables/disables the debug level for default logger. The debug level is enbaled in default.
func SetFile ¶
func SetFile(pattern string)
SetFile sets the file name <pattern> for file logging. Datetime pattern can be used in <pattern>, eg: access-{Ymd}.log. The default file name pattern is: Y-m-d.log, eg: 2018-01-01.log
func SetStdPrint ¶ added in v1.5.0
func SetStdPrint(open bool)
SetStdPrint sets whether ouptput the logging contents to stdout, which is false in default.
func SetWriter ¶
SetWriter sets the customized logging <writer> for logging. The <writer> object should implements the io.Writer interface. Developer can use customized logging <writer> to redirect logging output to another service, eg: kafka, mysql, mongodb, etc.
func Warningfln ¶
func Warningfln(format string, v ...interface{})
Types ¶
type Logger ¶
type Logger struct {
// contains filtered or unexported fields
}
