I call it cut-trivial-cases-off-early-to-keep-things-simple+together+not-overly-indented logic, hate logic statements barefoot in flow, and like logging in unattended processes:
Code:
if [ ! -s $msg ]
then
 date "+%Y-%m-%d %H:%M:%S ${0##*/} ($$) Discarding empty message '$msg'." >&2
 continue ?  exit ?
fi

NAME
MooseX::Log::Log4perl::Easy - A role for easy usage of logging in your Moose based modules based on MooseX::Log::Log4perl SYNOPSIS
package MyApp; use Moose; use Log::Log4perl qw(:easy); with 'MooseX::Log::Log4perl::Easy'; BEGIN { Log::Log4perl->easy_init(); } sub foo { my ($self) = @_; $self->log_debug("started bar"); ### logs with default class catergory "MyApp" $self->log_info('bar'); ### logs an info message $self->log('AlsoPossible')->fatal("croak"); ### log } DESCRIPTION
The Easy logging role based on the MooseX::Log::Log4perl logging role for Moose directly adds the logmethods for all available levels to your class instance. Hence it is possible to use $self->log_info("blabla"); without having to access a separate log attribute as in MooseX::Log::Log4perl; In case your app grows and you need more of the super-cow powers of Log4perl or simply don't want the additional methods to clutter up your class you can simply replace all code "$self->log_LEVEL" with "$self->log->LEVEL". You can use the following regex substitution to accomplish that: s/log(_(trace|debug|info|warn|error|fatal))/log->$2/g ACCESSORS
logger See MooseX::Log::Log4perl log See MooseX::Log::Log4perl log_fatal ($msg) Logs a fatal message $msg using the logger attribute. Same as calling $self->logger->fatal($msg) log_error ($msg) Logs an error message using the logger attribute. Same as calling $self->logger->error($msg) log_warn ($msg) Logs a warn message using the logger attribute. Same as calling $self->logger->warn($msg) log_info ($msg) Logs an info message using the logger attribute. Same as calling $self->logger->info($msg) log_debug ($msg) Logs a debug message using the logger attribute. Same as calling $self->logger->debug($msg) log_trace ($msg) Logs a trace message using the logger attribute. Same as calling $self->logger->trace($msg) SEE ALSO
