NAME

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

VERSION

       version 0.009001

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 up to 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{\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;
