logHandler
logHandler centralises application logging and log file rotation.
It exposes a set of preconfigured *log.Logger instances (Info, Warning, Error, Timing, Audit, etc.) which write to stdout/stderr and to rotating log files (via lumberjack).
How it works
- Initialises automatically via
init()when the package is imported. - Log file location is derived from the application paths and the configured application name.
- Most log categories can be enabled/disabled via
commonConfig. - Uses ANSI colour prefixes on non-Windows platforms.
Common loggers
A few of the exported loggers:
logHandler.InfoLoggerlogHandler.WarningLoggerlogHandler.ErrorLoggerlogHandler.PanicLoggerlogHandler.TimingLoggerlogHandler.AuditLoggerlogHandler.DatabaseLoggerlogHandler.CacheLogger
(There are more categories in logHandler.go.)
Usage
package main
import (
"github.com/mt1976/frantic-core/logHandler"
)
func main() {
logHandler.Info.Println("hello")
logHandler.Warning.Println("something to look at")
logHandler.Error.Println("something failed")
logHandler.InfoBanner("startup", "init", "application starting")
logHandler.Break()
}
Notes
- Because initialisation happens in
init(), importing this package will create/open the log writers immediately. - Rotation settings (max size, backups, age, compression) are taken from
commonConfig.
