log

log interface and default implementation for ccmonky.

Usage

inject logger

you can inject logger with the following interface(e.g. zap.SugaredLogger):

type LoggerInterface interface {
    Debug(msg string, keysAndValues ...interface{})
    Info(msg string, keysAndValues ...interface{})
    Error(msg string, keysAndValues ...interface{})
}

inject logger like this:

log.SetLogger("xxx", zap.S())

log levels

ccmonky/log support these log levels by default:

• ErrorLevel: error level, also can use short alias E
• InfoLevel: error level, also can use short alias I
• DebugLevel: error level, also can use short alias D

std log adapter

ccmonky/log has std log adapter support, you can use it like this:

• first, replace your std log import to github.com/ccmonky/log

that's all for existing libs, and then in app, replace the default logger like this:

// NOTE: 
// 1. default logger name is ""
// 2. appLogger is your app logger, which should implement `log.LoggerInterface`
log.SetLogger("", appLogger) 

then all your logs of libs will be recorded by appLogger, but note that, all the logs can only be recorded by appLogger in info level.

• second, if you are develop new libs, you can also support logger and levels like this:

log.Println(log.Ctx("xxx", log.E), ...)
log.Printf("%v %d %s", log.Ctx("yyy", log.D), code, msg)
