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.
