go-loggers
Package loggers provides useful tools for dealing with loggers, for the Go programming language.
Documention
Online documentation, which includes examples, can be found at: http://godoc.org/github.com/reiver/go-loggers
Example
logger := loggers.Writers{
FatalWriter: os.Stderr,
PanicWriter: os.Stderr,
ErrorWriter: os.Stderr,
WarnWriter: os.Stderr,
PrintWriter: os.Stdout,
DebugWriter: os.Stdout,
TraceWriter: osutil.Discard,
}
logger.Print("Hello world!")
logger.Warn("Be very very careful!")
logger.Fatalf("Finish %s", name)

type Logger ¶
type Logger interface {
Debug(...interface{})
Debugf(string, ...interface{})
Error(...interface{})
Errorf(string, ...interface{})
Fatal(...interface{})
Fatalf(string, ...interface{})
Panic(...interface{})
Panicf(string, ...interface{})
Print(...interface{})
Printf(string, ...interface{})
Trace(...interface{})
Tracef(string, ...interface{})
Warn(...interface{})
Warnf(string, ...interface{})
}
Logger represents a logger with levels.
Logger includes the Panic, Panicf, Print, Printf, Trace, and Tracef methods from the *log.Logger type in the Go standard library.
But it also adds the Debug, Debugf, Error, Errorf, Trace, Tracef, Warn, and Warnf methods that are common with loggers with "levels".
The "levels" in terms of least verbose to most verbose are:
· Fatal · Panic · Error · Warn · Print · Debug · Trace
var Discard Logger
Discard is a Logger on which all log calls succeed without doing anything.
The logging data is essentially "thrown away".
