Logger: custom logger package for Go.
Logger package help you easier write log to io.Writer. All methods fully support standard log package, but have extra features.
Install
For install logger, just run go get -u github.com/neliseev/logger or glide get github.com/neliseev/logger
Usage
Simple in main file you should initialise logger.
package main
import "github.com/neliseev/logger"
var log *logger.Log // Using log subsystem
func init() {
// Initialization log system
var err error
if log, err = logger.NewFileLogger("/var/log/example/main.log", 8); err != nil {
panic(err)
}
}
func main() {
log.Info("Starting main packge")
...
}
Logger automatically create all subfolder by defined path.
For re-use current initialised logger, just define var log *logger.Log, example:
package example
import "github.com/neliseev/logger"
var log *logger.Log // Using log subsystem
func Some() {
log.Debug("Hello, Wold!")
}

Types ¶
type Log ¶
type Log struct{}
func NewFileLogger ¶
NewFileLogger func - creating new file logger.
Fields:
LogFile - path to log file LogLevel - log level, possible levels: 0 - Emergency, with panic exit. 1 - Alert, with exit 2. 2 - Critical, with ext 1. 3 - Errors. 4 - Warnings. 5 - Notice. 6 - Info. 7 - Debug. 8 - Trace.
Example, for reusing current pointer to this logger, just define in package var log *logger.Log: var log *logger.Log // Using log subsystem
func init() {
// Initialization log system
var err error
if log, err = logger.NewFileLogger(environment.GetLogFile(), environment.GetLogLevel()); err != nil {
