GetBacktrace returns the caller backtrace content, the optional parameter <skip> specify the skipped backtraces offset from the end point.
获取文件调用回溯信息.
func GetPath ¶
func GetPath() string
GetPath returns the logging directory path for file logging. It returns empty string if no directory path set.
获取日志目录绝对路径
func GetWriter ¶
GetWriter returns the customed writer object, which implements the io.Writer interface. It returns nil if no customed writer set.
返回自定义的IO，默认为nil.

func SetDebug ¶
func SetDebug(debug bool)
SetDebug enables/disables the debug level for default logger. The debug level is enbaled in default.
设置是否允许输出DEBUG信息.
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
日志文件名称.
func SetPath ¶
func SetPath(path string)
SetPath sets the directory path for file logging.
日志日志目录绝对路径.
func SetStdPrint ¶ added in v1.5.0
func SetStdPrint(open bool)
SetStdPrint sets whether ouptput the logging contents to stdout, which is false indefault.
设置写日志的同时开启or关闭控制台打印，默认是关闭的
func SetWriter ¶
SetWriter sets the customed logging <writer> for logging. The <writer> object should implements the io.Writer interface. Developer can use customed logging <writer> to redirect logging output to another service, eg: kafka, mysql, mongodb, etc.
可自定义IO接口，IO可以是文件输出、标准输出、网络输出.
func Warningfln ¶
func Warningfln(format string, v ...interface{})
