BaseConfig is a configuration for LoggerBase.
func NewBaseConfig ¶
func NewBaseConfig() *BaseConfig
NewBaseConfig creates a new LoggerBase configuration.
type FileConfig ¶
type FileConfig struct {
*WriterConfig
Filename string
FileMode os.FileMode
}
FileConfig is a file based logger configuration.
func NewFileConfig ¶
func NewFileConfig() *FileConfig
NewFileConfig creates a new file logger configuration.
type Logger ¶
type Logger interface {
Add(vars ...interface{}) Logger
Log(lvl Level, msg string)
Debug(msg string)
Info(msg string)
Warn(msg string)
Error(msg string)
Fatal(msg string)
}
Logger is an interface for loggers.
func NewFileLogger ¶
func NewFileLogger(conf *FileConfig) (Logger, io.Closer, error)
NewFileLogger creates a new file logger.
func NewMultiLogger ¶
NewMultiLogger creates a new multi-logger from given loggers.
func NewStderrLogger ¶
func NewStderrLogger(conf *WriterConfig) (Logger, error)
NewStderrLogger creates a new logger for standard error stream.
func NewTestLogger ¶
func NewTestLogger(conf *WriterConfig, verbose bool) (Logger, error)
NewTestLogger creates a new test logger.
func NewWriterLogger ¶
func NewWriterLogger(conf *WriterConfig, out io.Writer) (Logger, error)
NewWriterLogger creates a new io.Writer based logger.
type LoggerBase ¶
type LoggerBase struct {
// contains filtered or unexported fields
}
LoggerBase is a base logger implementation shared by many other loggers.
func NewLoggerBase ¶
func NewLoggerBase(conf *BaseConfig, log LoggerFunc) (*LoggerBase, error)
NewLoggerBase creates a new LoggerBase.
func (*LoggerBase) Add ¶
func (l *LoggerBase) Add(vars ...interface{}) Logger
Add returns a new logger with added context variables. This function takes alternated key-value pairs (name1, val1, name1, val2, ...). The keys must be strings, but the values can be of any type.
func (*LoggerBase) Fatal ¶
func (l *LoggerBase) Fatal(msg string)
Fatal adds a new fatal message and then panics.
func (*LoggerBase) Log ¶
func (l *LoggerBase) Log(lvl Level, msg string)
Log adds a new log message with a given severity level.
type LoggerFunc ¶
LoggerFunc is a low-level logging function.
type WriterConfig ¶
type WriterConfig struct {
*BaseConfig
Prefix string
UTC bool
}
WriterConfig is an io.Writer based logger configuration.
func NewWriterConfig ¶
func NewWriterConfig() *WriterConfig
NewWriterConfig creates a new io.Writer based logger configuration.
