NAME

       Log::Contextual::SimpleLogger - Super simple logger made for playing with Log::Contextual

SYNOPSIS

	use Log::Contextual::SimpleLogger;
	use Log::Contextual qw( :log ),
	  -logger => Log::Contextual::SimpleLogger->new({ levels => [qw( debug )]});

	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      => Optional[ArrayRef[Str]],
	 levels_upto => Level,
	 coderef     => Optional[CodeRef], ] $conf"

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

       or

	my $l = Log::Contextual::SimpleLogger->new({
	  levels_upto => 'debug',
	  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_upto" enables all the levels upto and including the level passed.

       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{
}, @_;
	     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!' );

   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;
