# Log::Contextual::SimpleLogger(3pm)

Super simple logger made for playing with Log::Contextual

## 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;
```
