Log::Abstraction - Logging Abstraction Layer

VERSION

0.20

SYNOPSIS

use Log::Abstraction;

my $logger = Log::Abstraction->new(logger => 'logfile.log');

$logger->debug('This is a debug message');
$logger->info('This is an info message');
$logger->notice('This is a notice message');
$logger->trace('This is a trace message');
$logger->warn({ warning => 'This is a warning message' });

DESCRIPTION

The Log::Abstraction class provides a flexible logging layer on top of different types of loggers, including code references, arrays, file paths, and objects. It also supports logging to syslog if configured.

METHODS

new

my $logger = Log::Abstraction->new(%args);

Creates a new Log::Abstraction object.

The argument can be a hash, a reference to a hash or the logger value. The following arguments can be provided:

• carp_on_warn

  If set to 1, and logger is not given, call Carp:carp on warn().

• config_file

  Points to a configuration file which contains the parameters to new(). The file can be in any common format, including YAML, XML, and INI. This allows the parameters to be set at run time.

  On non-Windows system, the class can be configured using environment variables starting with "Log::Abstraction::". For example:

    export Log::Abstraction::script_name=foo
  

  It doesn't work on Windows because of the case-insensitive nature of that system.

• level

  The minimum level at which to log something, the default is "warning".

• logger

  A logger can be one or more of:

  • a code reference
  • an array reference
  • a file path
  • a file descriptor
  • an object
  • a hash of options, e.g. 'file' containing the filename, 'array' a reference to an array, or 'fd' containing a file descriptor to log to

  Defaults to Log::Log4perl.

• syslog - A hash reference for syslog configuration.

• script_name

  The name of the script. It's needed when syslog is given, if none is passed, the value is guessed.

Clone existing objects with or without modifications:

my $clone = $logger->new();

level

Get/set the minimum level to log at

messages

Return all the messages emmitted so far

debug

$logger->debug(@messages);

Logs a debug message.

info

$logger->info(@messages);

Logs an info message.

notice

$logger->notice(@messages);

Logs a notice message.

trace

$logger->trace(@messages);

Logs a trace message.

warn

$logger->warn(@messages);
$logger->warn(\@messages);
$logger->warn(warning => \@messages);

Logs a warning message. This method also supports logging to syslog if configured. If not logging mechanism is set, falls back to Carp.
