zap-wrap intergrates zap and log rotate, make zap easier to use
zap is excellent, but its configuration is too complicated. Though zap provides a default configuration, it's not enough for most projects.
If you:
- want to rotate the log file by time
- want clear old log files routinely
- want to write normal log to access.log and error info to error.log, just like nginx
this is for you!

{
"log_dir": "/home/deen/test",
"filename": "access.log",
"suffix": "%Y%m%d%H",
"rotate_duration": "1h",
"retain_age": "168h",
"soft_link": true,
"level": "debug"
},
{
"log_dir": "/home/deen/test",
"filename": "error.log",
"suffix": "%Y%m%d%H",
"rotate_duration": "1h",
"retain_age": "168h",
"soft_link": true,
"level": "warn"
}
]config above means:
- rotate once an hour
- old log file will be named as access.log.2019121420
- %Y: year
- %m: Month
- %d: day
- %H: hour
- %M: minute
- clear old log files which exist over 168 hours
- create symbol link named access.log to access.log.{current}, so that you can find the current log right away
- level >= warn -> error.log
- level >= debug && level < warn -> access.log
then
func main() {
var cfgs []zap_wrap.FileConfig
_ = json.Unmarshal(jsonConfig, &cfgs)
// So easy
logger, _ := zap_wrap.NewLogger(cfgs...)
logger.Debug("123", zap.Int("rand", rand.Intn(30)))
// In access.log: {"level":"debug","time":"2019-12-14T19:52:56+08:00","caller":"triple/main.go:28","msg":"123","rand":20}
logger.Error("ttt", zap.Int("rand", rand.Intn(30)))
// In error.log: {"level":"warn","time":"2019-12-14T19:52:56+08:00","caller":"triple/main.go:28","msg":"ttt","rand":5}
