Overview ¶
Package logger is a level-based logger for Go applications.
Example usage:
package main
import (
"github.com/FZambia/go-logger"
)
func main() {
name := "Alexander"
logger.INFO.Printf("Hello %s", name)
logger.ERROR.Println("Error")
}
Output:
[I]: 2016/09/09 19:41:13 Hello Alexander [E]: 2016/09/09 19:41:13 Error

Functions ¶
func SetLogFile ¶
SetLogFile sets the LogHandle to a io.writer created for the file behind the given file path. Will append to this file.
func SetLogThreshold ¶
func SetLogThreshold(level Level)
SetLogThreshold establishes a threshold where anything matching or above will be logged.
func SetStdoutThreshold ¶
func SetStdoutThreshold(level Level)
SetStdoutThreshold establishes a threshold where anything matching or above will be output.
Types ¶
type LevelLogger ¶
type LevelLogger struct {
// contains filtered or unexported fields
}
LevelLogger represents levelled logger.
func (*LevelLogger) Enabled ¶
func (n *LevelLogger) Enabled() bool
Enabled exists to prevent calling underlying logger methods when not needed. This can also called from library users before calling LevelLogger methods to reduce allocations.
func (*LevelLogger) Fatal ¶
func (n *LevelLogger) Fatal(v ...interface{})
Fatal calls underlying Logger Fatal func.
func (*LevelLogger) Fatalf ¶
func (n *LevelLogger) Fatalf(format string, v ...interface{})
Fatalf calls underlying Logger Fatalf func.
func (*LevelLogger) Fatalln ¶
func (n *LevelLogger) Fatalln(v ...interface{})
Fatalln calls underlying Logger Fatalln func.
func (*LevelLogger) Panic ¶
func (n *LevelLogger) Panic(v ...interface{})
Panic calls underlying Logger Panic func.
func (*LevelLogger) Panicf ¶
func (n *LevelLogger) Panicf(format string, v ...interface{})
Panicf calls underlying Logger Panicf func.
func (*LevelLogger) Panicln ¶
func (n *LevelLogger) Panicln(v ...interface{})
Panicln calls underlying Logger Panicln func.
func (*LevelLogger) Print ¶
func (n *LevelLogger) Print(v ...interface{})
Print calls underlying Logger Print func.
func (*LevelLogger) Printf ¶
func (n *LevelLogger) Printf(format string, v ...interface{})
Printf calls underlying Logger Printf func.
func (*LevelLogger) Println ¶
func (n *LevelLogger) Println(v ...interface{})
Println calls underlying Logger Println func.
