logger - package provides log.Logger adapters
Quick start
go get github.com/gregoryv/logger
Use in your code
type Car struct {
logger.Logger
}
car := &Car{logger.New()}
car.Log("brakes are failing")
car.Logf("reached speed limit %s", 100)
or when testing the logger can be replaced by testing.T
func Test_car_speed(t *testing.T) {
car := &Car{t}
// asserts here
}
Documentation

Overview ¶
Package logger adapts log.Logger with Log and Logf funcs.
There are two benefits of this, the smaller Logger interface limits logging to output only and can easily be replaced by the testing.T object during testing.
type Car struct {
logger.Logger
}
car := &Car{logger.New()}
car.Log("brakes are failing")
car.Logf("reached speed limit %s", 100)
Example (Silent) ¶
package main
import (
"github.com/gregoryv/logger"
)
func main() {
l := logger.Silent
l.Log("nada")
l.Logf("%s", "nada")
}

Log(args ...interface{})
Logf(format string, args ...interface{})
}
var Silent Logger = silent(0)

type Wrapped struct {
// contains filtered or unexported fields
}
func New ¶
func New() *Wrapped
Returns a logger with log.LstdFlags|log.Lshortfile that writes to stderr
Example ¶
package main
import (
"github.com/gregoryv/logger"
)
func main() {
type Car struct {
logger.Logger
}
car := &Car{logger.New()}
car.Log("brakes are failing")
car.Logf("reached speed limit %v", 100)
}
Output:
func NewProgress ¶
func NewProgress() *Wrapped
