NAME

Log::Contextual::TeeLogger - Output to more than one logger

VERSION

version 0.009001

SYNOPSIS


            

              
              
use Log::Contextual::SimpleLogger;
use Log::Contextual::TeeLogger;
use Log::Contextual qw( :log ),
  -logger => Log::Contextual::TeeLogger->new({ loggers => [
    Log::Contextual::SimpleLogger->new({ levels => [ 'debug' ] }),
    Log::Contextual::SimpleLogger->new({
      levels => [ 'info' ],
      coderef => sub { print @_ },
    }),
  ]});
## docs below here not yet edited
log_info { 'program started' }; # no-op because info is not in levels
sub foo {
  log_debug { 'entered foo' };
  ...
}

DESCRIPTION

This module is a simple logger made mostly for demonstration and initial experimentation with Log::Contextual. We recommend you use a real logger instead. For something more serious but not overly complicated, take a look at Log::Dispatchouli.

METHODS

new

Arguments: Dict[ levels => ArrayRef[Str], coderef => Optional[CodeRef] ] $conf


            

              
              
my $l = Log::Contextual::SimpleLogger->new({
  levels => [qw( info warn )],
  coderef => sub { print @_ }, # the default prints to STDERR
});

Creates a new SimpleLogger object with the passed levels enabled and optionally a CodeRef may be passed to modify how the logs are output/stored.

Levels may contain:


            

              
              
trace
debug
info
warn
error
fatal

$level

Arguments: @anything

All of the following six methods work the same. The basic pattern is:


            

              
              
sub $level {
  my $self = shift;
  print STDERR "[$level] " . join qq{\n}, @_;
      if $self->is_$level;
}

trace


            

              
              
$l->trace( 'entered method foo with args ' join q{,}, @args );

debug


            

              
              
$l->debug( 'entered method foo' );

info


            

              
              
$l->info( 'started process foo' );

warn


            

              
              
$l->warn( 'possible misconfiguration at line 10' );

error


            

              
              
$l->error( 'non-numeric user input!' );

fatal


            

              
              
$l->fatal( '1 is never equal to 0!' );

Note: fatal does not call die for you, see "EXCEPTIONS AND ERROR HANDLING" in Log::Contextual

is_$level

All of the following six functions just return true if their respective level is enabled.

is_trace


            

              
              
say 'tracing' if $l->is_trace;

is_debug


            

              
              
say 'debuging' if $l->is_debug;

is_info


            

              
              
say q{info'ing} if $l->is_info;

is_warn


            

              
              
say 'warning' if $l->is_warn;

is_error


            

              
              
say 'erroring' if $l->is_error;

is_fatal


            

              
              
say q{fatal'ing} if $l->is_fatal;
