=head1 NAME
Acme::Crux::Plugin::Log - The Acme::Crux plugin for logging in your application
=head1 SYNOPSIS
# In startup
$app->plugin('Log');
$app->plugin('Log', undef, { ... options ... });
# In application
$app->log->trace('Whatever');
$app->log->debug('You screwed up, but that is ok');

=head1 DESCRIPTION
The Acme::Crux plugin for logging in your application
=head1 OPTIONS
This plugin supports the following options
=head2 autoclean
$app->plugin(Log => undef, {autoclean => 1});
This option enables cleaning (closing handler or syslog) on DESTROY
Default: C<logautoclean> command line option or C<logautoclean> application argument
or C<LogAutoclean> configuration value or C<0> otherwise
=head2 color
$app->plugin(Log => undef, {color => 1});
This option enables colorize log messages with the available levels using L<Term::ANSIColor>
Default: C<logcolorize> command line option or C<logcolorize> application argument
or C<LogColorize> configuration value or C<0> otherwise
=head2 facility
$app->plugin(Log => undef, {facility => 'user'});
This option sets facility for logging
Available standard facilities: C<auth>, C<authpriv>, C<cron>, C<daemon>, C<ftp>,
C<kern>, C<local0>, C<local1>, C<local2>, C<local3>, C<local4>, C<local5>, C<local6>,
C<local7>, C<lpr>, C<mail>, C<news>, C<syslog>, C<user> and C<uucp>
Default: C<logfacility> command line option or C<logfacility> application argument
or C<LogFacility> configuration value or C<user> otherwise
=head2 file
$app->plugin(Log => undef, {file => '/var/log/myapp.log'});
Log file path used by "handle"
Default: C<logfile> command line option or C<LogFile> configuration value
or C<logfile> application argument or C</var/log/$moniker/$moniker.log> otherwise
=head2 format
$app->plugin(Log => undef, {format => sub {...}});
A callback function for formatting log messages. See L<Acrux::Log/format>
Default: C<logformat> application argument or C<undef> otherwise
=head2 handle
$app->plugin(Log => undef, {
handle => IO::Handle->new_from_fd(fileno(STDOUT), "w")
});
Log filehandle, defaults to opening "file" or uses syslog if file not specified
Default: C<loghandle> application argument or C<undef> otherwise
=head2 ident
$app->plugin(Log => undef, {ident => 'myapp'});
The B<ident> is prepended to every B<syslog> message
Default: C<logident> command line option or C<logident> application argument
or C<LogIdent> configuration value or script name C<basename($0)> otherwise
=head2 level
$app->plugin(Log => undef, {level => 'debug'});
This option sets log level
Predefined log levels: C<fatal>, C<error>, C<warn>, C<info>, C<debug>, and C<trace> (in descending priority).
The syslog supports followed additional log levels: C<emerg>, C<alert>, C<crit'> and C<notice> (in descending priority).
But we recommend not using them to maintain compatibility.
See also L<Acrux::Log/level>
Default: C<loglevel> command line option or C<loglevel> application argument

=head1 DESCRIPTION
Acrux::Log is a simple logger for Acrux logging
=head2 new
my $log = Acrux::Log->new(
logopt => 'ndelay,pid',
facility => 'user',
level => 'debug',
ident => 'test.pl',
autoclean => 1,
logopt => 'ndelay,pid',
);
With default attributes
use Mojo::Log;
my $log = Acrux::Log->new( logger => Mojo::Log->new );
$log->error("Test error message");
This is example with external loggers
=head1 ATTRIBUTES
This class implements the following attributes
=head2 autoclean
autoclean => 1
This attribute enables cleaning (closing handler or syslog) on DESTROY
=head2 color
color => 1
Colorize log messages with the available levels using L<Term::ANSIColor>, defaults to C<0>
=head2 facility
facility => 'user'
This attribute sets facility for logging
Available standard facilities: C<auth>, C<authpriv>, C<cron>, C<daemon>, C<ftp>,
C<kern>, C<local0>, C<local1>, C<local2>, C<local3>, C<local4>, C<local5>, C<local6>,
C<local7>, C<lpr>, C<mail>, C<news>, C<syslog>, C<user> and C<uucp>
Default: C<user> (Sys::Syslog::LOG_USER)
See also L<Sys::Syslog/Facilities>
=head2 file
file => '/var/log/myapp.log'
Log file path used by "handle"
=head2 format
format => sub {...}
A callback function for formatting log messages
format => sub {
my ($time, $level, @lines) = @_;
return "[$time] [$level] " . join (' ', @lines) . "\n";
}
This callback routine must return formatted string for the log line
=head2 handle
handle => IO::Handle->new_from_fd(fileno(STDOUT), "w")
Log filehandle, defaults to opening "file" or uses syslog if file not specified
=head2 ident
ident => 'myapp'
The B<ident> is prepended to every B<syslog> message
Default: script name C<basename($0)>
=head2 level
level => 'debug'
There are six predefined log levels: C<fatal>, C<error>, C<warn>, C<info>, C<debug>, and C<trace> (in descending priority).
The syslog supports followed additional log levels: C<emerg>, C<alert>, C<crit'> and C<notice> (in descending priority).
But we recommend not using them to maintain compatibility.
Your configured logging level has to at least match the priority of the logging message.
If your configured logging level is C<warn>, then messages logged with info(), debug(), and trace()
will be suppressed; fatal(), error() and warn() will make their way through, because their
priority is higher or equal than the configured setting.
Default: C<debug>
See also L<Sys::Syslog/Levels>
=head2 logger
logger => Mojo::Log->new()
This attribute perfoms to set predefined logger, eg. Mojo::Log
Default: C<undef>
=head2 logopt
logopt => 'ndelay,pid'
This attribute contains zero or more of the options detailed in L<Sys::Syslog/openlog>
Default: C<'ndelay,pid'>
=head2 prefix
prefix => '>>>'
The B<prefix> is prepended to every C<handled> log message
Default: null
=head2 short
short => 1
Generate short log messages without a timestamp but with log level prefix, defaults to C<0>
=head1 METHODS
This class implements the following methods
=head2 alert
$log->alert('Action must be taken immediately');
$log->alert('Real', 'problem');
Log C<alert> message
=head2 crit
$log->crit('Its over...');
$log->crit('Bye', 'bye');
Log C<crit> message (See L</fatal> method)
=head2 debug
$log->debug('You screwed up, but that is ok');
$log->debug('All', 'cool');
Log C<debug> message
=head2 emerg
$log->emerg('System is unusable');
$log->emerg('To', 'die');
Log C<emerg> message
=head2 error
$log->error('You really screwed up this time');
$log->error('Wow', 'seriously');
Log C<error> message
=head2 fatal
$log->fatal('Its over...');
$log->fatal('Bye', 'bye');
Log C<fatal> message
=head2 info
$log->info('You are bad, but you prolly know already');
$log->info('Ok', 'then');
Log C<info> message
=head2 level
my $level = $log->level;
$log = $log->level('debug');
Active log level, defaults to debug.
Available log levels are C<trace>, C<debug>, C<info>, C<notice>, C<warn>, C<error>,
C<fatal> (C<crit>), C<alert> and C<emerg>, in that order
=head2 logger
my $logger = $log->logger;
This method returns the logger object or undef if not exists
=head2 notice
$log->notice('Normal, but significant, condition...');
$log->notice('Ok', 'then');
Log C<notice> message
=head2 provider
print $log->provider;
Returns provider name (C<external>, C<handle>, C<file> or C<syslog>)
=head2 trace
$log->trace('Whatever');
$log->trace('Who', 'cares');
Log C<trace> message
=head2 warn
$log->warn('Dont do that Dave...');
$log->warn('No', 'really');
Log C<warn> message
