## Golang logging library
[![godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](https://godoc.org/github.com/op/go-logging) [![build](https://img.shields.io/travis/op/go-logging.svg?style=flat)](https://travis-ci.org/op/go-logging)
Package logging implements a logging infrastructure for Go. Its output format
is customizable and supports different logging backends like syslog, file and
memory. Multiple backends can be utilized with different log levels per backend
and logger.
## Example
Let's have a look at an [example](examples/example.go) which demonstrates most
of the features found in this library.
[![Example Output](examples/example.png)](examples/example.go)
```go
package main
import (
"os"
"github.com/op/go-logging"
)
var log = logging.MustGetLogger("example")
// Example format string. Everything except the message has a custom color
// which is dependent on the log level. Many fields have a custom output
// formatting too, eg. the time returns the hour down to the milli second.
var format = logging.MustStringFormatter(
"%{color}%{time:15:04:05.000} %{shortfunc} ▶ %{level:.4s} %{id:03x}%{color:reset} %{message}",
)
// Password is just an example type implementing the Redactor interface. Any
// time this is logged, the Redacted() function will be called.
type Password string
func (p Password) Redacted() interface{} {
return logging.Redact(string(p))
}
func main() {
// For demo purposes, create two backend for os.Stderr.
backend1 := logging.NewLogBackend(os.Stderr, "", 0)
backend2 := logging.NewLogBackend(os.Stderr, "", 0)
// For messages written to backend2 we want to add some additional
// information to the output, including the used log level and the name of
// the function.
backend2Formatter := logging.NewBackendFormatter(backend2, format)
// Only errors and more severe messages should be sent to backend1
backend1Leveled := logging.AddModuleLevel(backend1)
backend1Leveled.SetLevel(logging.ERROR, "")
// Set the backends to be used.
logging.SetBackend(backend1Leveled, backend2Formatter)
log.Debug("debug %s", Password("secret"))
log.Info("info")
log.Notice("notice")
log.Warning("warning")
log.Error("err")
log.Critical("crit")
}
```
## Installing
### Using *go get*
$ go get github.com/op/go-logging
After this command *go-logging* is ready to use. Its source will be in:
$GOROOT/src/pkg/github.com/op/go-logging
You can use `go get -u` to update the package.
## Documentation
For docs, see http://godoc.org/github.com/op/go-logging or run:
$ godoc github.com/op/go-logging
## Additional resources
* [wslog](https://godoc.org/github.com/cryptix/go/logging/wslog) -- exposes log messages through a WebSocket.

// %{id} Sequence number for log message (uint64).
// %{pid} Process id (int)
// %{time} Time when log occurred (time.Time)
// %{level} Log level (Level)
// %{module} Module (string)
// %{program} Basename of os.Args[0] (string)
// %{message} Message (string)
// %{longfile} Full file name and line number: /a/b/c/d.go:23
// %{shortfile} Final file name element and line number: d.go:23
// %{color} ANSI color based on log level
//
// For normal types, the output can be customized by using the 'verbs' defined
// in the fmt package, eg. '%{id:04d}' to make the id output be '%04d' as the
// format string.
//
// For time.Time, use the same layout as time.Format to change the time format
// when output, eg "2006-01-02T15:04:05.999Z-07:00".
//
// For the 'color' verb, the output can be adjusted to either use bold colors,
// i.e., '%{color:bold}' or to reset the ANSI attributes, i.e.,
// '%{color:reset}' Note that if you use the color verb explicitly, be sure to
// reset it or else the color state will persist past your log message. e.g.,
// "%{color:bold}%{time:15:04:05} %{level:-8s}%{color:reset} %{message}" will
// just colorize the time and level, leaving the message uncolored.
//
// There's also a couple of experimental 'verbs'. These are exposed to get
// feedback and needs a bit of tinkering. Hence, they might change in the
// future.
//
// Experimental:
// %{longpkg} Full package path, eg. github.com/go-logging
// %{shortpkg} Base package path, eg. go-logging
// %{longfunc} Full function name, eg. littleEndian.PutUint32
// %{shortfunc} Base function name, eg. PutUint32
