a simple way turn logging messages on and off. The gui config
|
|
window will let you enable & disable logging while your app is
|

running.
|

|
|
Example:
|
|
|
|
log.Log(NETWARN, "socket connection failed to 127.0.0.1:8080")
|
|
|
|
In your package, register NETWARN:
|
|
|
|
var NETWARN *log.LogFlag
|
|
NETWARN = log.NewFlag("NETWARN", true, "go.wit.com/log", "log", "network warnings!")
|
|

|
