This is a simple wrapper around the standard go runtime logger with only one goal:

• ADD DEBUG OUTPUT FUNCTIONS.

Functions that are available for the caller:

• All those in "log" AND
• Debug
• Debugf
• Debugln

On the package base level these functions will print output only if the DEBUG environment variable is present and have some non-empty value.

Otherwise, one can construct a new logger:

func New(out io.Writer, prefix string, flag int, debug bool) *Logger

for the flags, one could use the values from the standard logger.

Import it in your project replacing "log" import entry:

import (
  log "github.com/rusq/dlog"
)

Use:

log.Debug("hello debug!")

Check if debug is enabled:

log.IsDebug()
