Constants ¶
const ( LogOff int = 0 LogFatal int = 1 LogError int = 2 LogWarn int = 3 LogInfo int = 4 LogDebug int = 5 LogTrace int = 6 LogAll int = 7 )
Logger level constants
Variables ¶
var (
ErrClientNil = errors.New("the client pointer was nil")
)
Errors used throughout the package.
Functions ¶
This section is empty.
Types ¶
type Config ¶
type Config struct {
Prefix string `json:"prefix" yaml:"prefix"`
LogLevel string `json:"level" yaml:"level"`
AddTimeStamp bool `json:"add_timestamp" yaml:"add_timestamp"`
JSONFormat bool `json:"json_format" yaml:"json_format"`
}
Config holds configuration options for a logger object.
type Logger ¶
type Logger struct {
// contains filtered or unexported fields
}
Logger is an object with support for levelled logging and modular components.
func (*Logger) NewModule ¶
NewModule creates a new logger object from the previous, using the same configuration, but adds an extra prefix to represent a submodule.
type Modular ¶
type Modular interface {
NewModule(prefix string) Modular
Fatalf(format string, v ...interface{})
Errorf(format string, v ...interface{})
Warnf(format string, v ...interface{})
Infof(format string, v ...interface{})
Debugf(format string, v ...interface{})
Tracef(format string, v ...interface{})
Fatalln(message string)
Errorln(message string)
Warnln(message string)
Infoln(message string)
Debugln(message string)
Traceln(message string)
}
Modular is a log printer that allows you to branch new modules.
func Wrap ¶ added in v0.23.5
func Wrap(l PrintFormatter) Modular
Wrap a PrintFormatter with a log.Modular implementation. Log level is set to INFO, use WrapAtLevel to set this explicitly.
func WrapAtLevel ¶ added in v0.23.5
func WrapAtLevel(l PrintFormatter, level int) Modular
WrapAtLevel wraps a PrintFormatter with a log.Modular implementation with an explicit log level.
type PrintFormatter ¶ added in v0.23.5
type PrintFormatter interface {
Printf(format string, v ...interface{})
Println(v ...interface{})
}
PrintFormatter is an interface implemented by standard loggers.
