NAME ^

Debug::STDERR - provide debug() method and redirect STDERR.

SYNOPSIS ^

  use strict;
  use warnings;

  # set environment variables, or set and export it for your shell

  BEGIN {
    $ENV{DEBUG} = 1;
    $ENV{STDERR2LOG} = "log.out";
  }

  use Debug::STDERR;

  debug( "foo" => { bar => "baz" });

DESCRIPTION ^

Debug::STDERR provides debug() method and redirect STDERR out to a file.

If you want to use it, you should set tow environment variables for your shell.

   $ export DEBUG=1
   $ export STDERR2LOG=log.out

or edit $ENV on BEGIN block. ( you must put it on before the line 'use Debug::STDERR;' )

If you set only 'DEBUG' variable, the debug messages out to STDERR. Furthermore if you set 'STDERR2LOG' variable, the data for STDERR will be redirect to log file.
