simplelogger

simplelogger is a small logger with no external dependencies. It provides a basic logger API with useful configuration options such as log level, time-stamping and color output.

Installation

Run the following to install simplelogger:

$ go get -u github.com/Renni771/simplelogger

Usage

Simply call the GetLogger function and provide a LoggerOptions struct to configure simplelogger:

  logger := simplelogger.GetLogger(simplelogger.LoggerOptions{
    LogLevel:            simplelogger.LogLevelInfo,
    WithTimeStamps:      true,
    WithColorizedOutput: true,
  })

  logger.Debug("Here's a debug message...")
  logger.Info("Just some info.")
  logger.Warn("I'm warning you!")
  logger.Error("An error occurred!")
  logger.Fatal("Fatality")

Log level

simplelogger supports 7 different log levels with increasing severity:

  LogLevelVerbose   // lowest severity
  LogLevelDebug
  LogLevelInfo
  LogLevelWarn
  LogLevelError
  LogLevelFatal     // highest severity
  LogLevelSilent

Setting the log level to LogLevelWarn will, for example, suppress all LogLevelVerbose, LogLevelDebug, LogLevelInfo logs.
