logex

A leveled log pkg for go. Very easy to use and fully customizes. Most importantly, it output goroutine-id in log line. output example:

NOTICE: 08-10 15:15:03.365: 3: basic_usage.go:25: note the third field of log line is the goroutine-id

Example

• example.go:

  // The very basic usage of logex pkg
  package main
  
  import (
      "fmt"
      "os"
      "time"
  )
  
  import "github.com/wuxicn/logex"
  
  func main() {
      if err := SetUpFileLogger("./log", "test", nil); err != nil {
          fmt.Fprintln(os.Stderr, "init file logger failed\n")
          os.Exit(1)
      }
      logex.SetLevel(logex.NOTICE) // set log level to NOTICE,
                                   // so DEBUG and TRACE logs won't show
                                   // in log file
  
      logex.Debug("this message won't show")
      logex.Trace("this message won't show neither")
      logex.Notice("hi, pi is:", 3.1415926)
      logex.Warning("this is warning message")
      logex.Fatal("all logs will output to os.Stderr by default")
  }
