NAME
Log::ger::Screen - Convenient packaging of Log::ger + Lg:Output::Screen + Lg:Level::FromVar + Lg:Level::FromEnv for one-liner
VERSION
version 0.005
SYNOPSIS
Mostly in one-liners:
% perl -MLog::ger::Screen -E'log_warn "blah..."; ...'
Set level from package variable (see Log::ger::Level::FromVar for more details):
% perl -E'BEGIN { $Default_Log_Level = 'info' } use Log::ger::Screen; ...'
Set level from environment variable (see Log::ger::Level::FromEnv for more details):
% TRACE=1 perl ...
But you can certainly use this module in your CLI script, as a more lightweight alternative to Log::ger::App when you only want to output log to screen:
#!perl
use strict;
use warnings;
BEGIN { our $Default_Log_Level = 'info' }
use Log::ger::Screen;
use Log::ger;
use Getopt::Long;
log_debug "Starting program ...";
...
log_debug "Ending program ...";
DESCRIPTION
This is just a convenient packaging of:
use Log::ger::Level::FromVar;
use Log::ger::Level::FromEnv;
use Log::ger::Output 'Screen';
use Log::ger; # in the caller's package
mostly for one-liner usage, but you are also welcome to use it in your CLI scripts.
