If I want to use logging for different modules, I would have destinations (like file) depending on the module.

Has it been planned or envisaged to write to a specific logger and not to all managed loggers ?

For example, I would create a console and a file logged for the main part of an application, but also would have a specific logger for a module (let's call it "module"). That would be convenient to have InfoTo(), WarnTo(), etc... for this:

log.NewFileWithName("module", 100, log.FileConfig{
  Level: log.LevelInfo,
  Filename: "module.log"
})

log.InfoTo("module", "log this")
log.WarnTo("module", "warn this")

A complete management of different logger sources with associated destinations would be better, but I think it's a good compromise to add such a functionnality without breaking compatibility.

Using this file:

package main
import aa "gopkg.in/clog.v1"
func main() {
   aa.New(aa.CONSOLE, aa.ConsoleConfig{})
   aa.Info("bbbbb")
   aa.Info("ccccc")
}

I get this result:

2019/06/14 20:38:47 [ INFO] bbbbb

Notice only one message is printed.

I use clog as logging library in my project.
I meet an weird issue that the outdated log file is not deleted when rotate is on.

My go version is

$ go version
go version go1.13.5 linux/amd64

clog was initialled with the code below:

func New(c Config) (err error) {
	name := filepath.Join(c.Path, c.LogName)

	if c.IsConsole {
		_ = clog.NewConsole()
	}

	return clog.NewFile(clog.FileConfig{
		Level:    c.logLevel(),
		Filename: name,
		FileRotationConfig: clog.FileRotationConfig{
			Rotate:  true,
			Daily:   true,
			MaxSize: c.MaxSize,
			MaxDays: c.MaxDays,
		},
	})
}

The daemon is running since last Thursday.
The MaxDays is set to 1, but the old log is still there.

$ ls -1

daemon.log.2019-12-12

Did I make anything wrong or miss anything ?
Thanks

E.g. log.Infos, log.Errors

The first log is not written everytime

package main

import log "unknwon.dev/clog/v2"

func init() {
	if err := log.NewConsole(); err != nil {
                panic("unable to create new logger: " + err.Error())
        }
}

func main() { log.Trace("This will not print") } // will not print anything

But everything get written correctly once you trigger a new one

func main() {
       log.Trace("This will print")
       log.Trace("This will print too")
}

EDIT : after some more testing I found the behavior to be inconsistant,
I ran the same program around 5 times and had different results

func main() {
	log.Trace("something")
	log.Trace("something")
}

E.g. log.Infos, log.Errors
