SYNOPSIS

     use Log::Any::IfLOG '$log';

DESCRIPTION

    This module is a drop-in replacement/wrapper for Log::Any to be used
    from your modules. This is a quick-hack solution to avoid the cost of
    loading Log::Any under "normal condition". Since Log::Any 1.00, startup
    overhead increases to about 7-10ms on my PC/laptop (from under 1ms for
    the previous version). Because I want to keep startup overhead of CLI
    apps under 50ms (see Perinci::CmdLine::Lite) to keep tab completion
    from getting a noticeable lag, every millisecond counts.

    This module will only load Log::Any when "logging is enabled".
    Otherwise, it will just return without loading anything. If $log is
    requested in import, a fake object is returned that responds to methods
    like debug, is_debug and so on but will do nothing when called and just
    return 0.

    To determine "logging is enabled":

      * Is $ENABLE_LOG defined?

      This package variable can be used to force "logging enabled" (if
      true) or "logging disabled" (if false). Normally, you don't need to
      do this except for testing.

      * Is Log::Any is already loaded (from %INC)?

      If Log::Any is already loaded, it means we have taken the overhead
      hit anyway so logging is enabled.

      * Is one of log-related environment variables true?

      If one of LOG, TRACE, or DEBUG, or VERBOSE, or QUIET, or LOG_LEVEL is
      true then logging is enabled. These variables are used by
      Perinci::CmdLine.

      Otherwise, logging is disabled.

ENVIRONMENT

 LOG => bool

 TRACE => bool

 DEBUG => bool

 VERBOSE => bool

 QUIET => bool

 LOG_LEVEL => str

VARIABLES

 $ENABLE_LOG => bool

    This setting can be forced to force loading Log::Any or not.
