golang logger manager
Log plug-ins that can be customized appropriately. Support concurrent logging.We used the ring queue and sync.Pool . and use queue instead of lock(sync.Mutex) write security. Easy to use. Customized. Log files can be customized by size and date. Both supported.

Writen 14M data into a log file.If you don't want set your path, debug, time and so on. It can still be used
- Import
import "github.com/slclub/glog"- API
Like fmt.Pringln
glog.Info("[HELLO][WORLD]", "MY FIST START", "PID[", int , "]")
glog.Debug("[HELLO][WORLD]", "MY FIST START", "PID[", int , "]")
glog.Warnning("[HELLO][WORLD]", "MY FIST START", "PID[", int , "]")
glog.Error("[HELLO][WORLD]", "MY FIST START", "PID[", int , "]")
glog.Fatal("[HELLO][WORLD]", "MY FIST START", "PID[", int , "]")- An example.
func concurrencyLog(send_time int) {
for i := 0; i < send_time; i++ {
glog.Debug("testing something.")
glog.Info("Oh my god. you are so clever.")
glog.Warnning("an waring log!")
}
fmt.Println("[PRINT][FINISH]")
}
func main() {
glog.Set("path", "", "mylog")
go concurrencyLog(1000)
go concurrencyLog(1000)
time.Sleep(1800 * time.Second)
}
- Log default style. before you customized
2020-05-20 00:20:38 INFO Oh my god. you are so clever.
2020-05-20 00:20:38 WARN an waring log!
2020-05-20 00:20:38 DEBUG testing something.
2020-05-20 00:20:38 INFO Oh my god. you are so clever.
2020-05-20 00:20:38 WARN an waring log!
2020-05-20 00:20:38 DEBUG testing something.
2020-05-20 00:20:38 INFO Oh my god. you are so clever.It's actually a function
Set(field string, value ...interface{})
In you code maybe like glog.Set(xxx, xxx)
- Log file path setting.
// log file abs path and relative path. can both set them.
// In fact, the two paths correspond to the project path and its path respectively
// You can choose only one of them to set.
Set("path", "abs_path", "rel_path")- Log name prefix
// We offen concatenated log name with string and time and random number.
// here you just set the string part of the name.
Set("name", "kawayi")- Log time settings
// Need to hide the time of each log line
// false : hidden, true: show ;
// default format : 2020-50-19 00:00:00
Set("show_time", false)- Log head info
// Log files are changed. when a new file was created. this string you added will be set to top of file.
Set("head", "auth@kawayi\nBbegin a new log every day\n")- Log debug settings.
// false: Hide data printed by a Debug method. true: show all
Set("debug", false)
// The second param also can be a number. The permission setting here is designed by bit calculation
// Add and subtract are supported for these numbers. You can use addition and subtraction to control permissions
// Very delicate to control
Set("debug", int)
const (
// LEVEL
LEVEL_INFO = 1
LEVEL_DEBUG = 2
LEVEL_WARNNING = 4
LEVEL_ERROR = 8
LEVEL_FATAL = 16
TRACE_INFO = 32
TRACE_DEBUG = 64
TRACE_WARNNING = 128
TRACE_ERROR = 256
TRACE_FATAL = 512
)Wrap glog as you like. If you wanna wrap more one layer. you should use InfoDepth, DebugDepth, WarnningDepth, ErrorDepth .. etc.
- InfoDepth(depth int, args ...interface{})
- DebugDepth(depth int, args ...interface{})
- WarnningDepth(depth int, args ...interface{})
- ErrorDepth(depth int, args ...interface{})
- FatalDepth(depth int, args ...interface{})// @param depth int
// You should add as many layers of as you wraped. this will be used by runtime.Caller().
// Its function is to print the number of lines of code and file name.
// @param args ...interface{}
// You can use it like fmt.Pringln . Their parameters are the same.
