NAME
Log::Any::IfLOG - Load Log::Any only if LOG environment variable is true
VERSION
This document describes version 0.02 of Log::Any::IfLOG (from Perl distribution Log-Any-IfLOG), released on 2015-03-24.
SYNOPSIS
use Log::Any::IfLOG '$log';DESCRIPTION
This module will load Log::Any only when LOG environment variable is true. Otherwise, the module is not loaded and if user imports $log, a dumb object will be returned instead that will accept any method but return false.
This is a quick-hack solution to avoid the cost of loading Log::Any under "normal condition" (when LOG is not set to true). Since Log::Any 1.00, startup overhead increases to about 7ms on my PC (from under 1ms for the previous version). Since 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.
ENVIRONMENT
LOG => bool
If set to true, will load Log::Any as usual. Otherwise, won't load Log::Any and will return a dumb object in $log instead.
