Golang Logging Library
This Golang library provides an easy interface for logging to console and files. The library provides support for multiple log levels.
Supported Log levels
The following log levels are supported when logging.
- TRACE
- DEBUG
- INFO
- WARNING
- ERROR
- FATAL
Logging to fatal will terminate the program.
Usage
To create a new logger specify a log file and a log level. Specifying an empty string "" for the log file will return a console only logger.
log := logger.NewLogger("/tmp/mylogfile.log", logger.INFO)
This will create an INFO level logger that will log to the path
/tmp/mylogfile.log.
To log to info:
log.Info("My log message")
To log to error:
log.Error("My error message")
You can even use formatting
myString := "World"
myInt := 47
log.Debug("Hello, %s: %d", myString, myInt)
Yields Hello, World: 47

Log is an interface describing the required functions for a logger.
type Logger ¶
type Logger struct {
// contains filtered or unexported fields
}
Logger is a log handler for various levels of logging.
func (*Logger) ConsoleInfo ¶
ConsoleInfo is a helper function that logs to both the console and Info log.
