Documentation

Overview

Package logx provides very useful utilities for logging. I hesitate to create it, for fear we will add too much stuff to it. But LogEvery seems worth it. This packages uses the MIT license, to respect the corresponding license from kami-zh/go-capture

• func CaptureLog(logger *log.Logger, f func()) (string, error)
• type Logger
  • func NewLogEvery(logger *log.Logger, interval time.Duration) Logger

Variables

var Debug = log.New(ioutil.Discard, "DEBUG: ", 0)

Debug is the package logger for debug messages. Debug messages are discarded if LogxDebug is set false.

var (
	// LogxDebug controls whether the debug logger is enabled or not. In almost all cases
	// you should rely on the flag to change this value. If critical, you may change the
	// value using LogxDebug.Set("true") or LogxDebug.Set("false").
	LogxDebug = logxDebug(false)
)
