   is a Log::Report::Dispatcher

SYNOPSIS

 dispatcher Log::Report::Dispatcher::File => 'stderr'
   , to => \*STDERR, accept => 'NOTICE-';
 
 # close a dispatcher
 dispatcher close => 'stderr';
 
 # let dispatcher open and close the file
 dispatcher FILE => 'mylog', to => '/var/log/mylog'
   , charset => 'utf-8';
 ...
 dispatcher close => 'mylog';  # will close file
 
 # open yourself, then also close yourself
 open OUT, ">:encoding('iso-8859-1')", '/var/log/mylog'
     or fault "...";
 dispatcher FILE => 'mylog', to => \*OUT;
 ...
 dispatcher close => 'mylog';  
 close OUT;
 
 # dispatch into a scalar
 my $output = '';

 dispatcher FILE => 'into-scalar', to => \$outfile;
 ...
 dispatcher close => 'into-scalar';
 print $output;

DESCRIPTION

This basic file logger accepts an file-handle or filename as destination.

[1.00] writing to the file protected by a lock, so multiple processes can write to the same file.

Log::Report::Dispatcher::File->new($type, $name, %options)

 -Option       --Defined in             --Default

  charset        Log::Report::Dispatcher  LOCALE

  to                                      <required>

accept => REASONS

charset => CHARSET

format => CODE|'LONG'

[1.00] process each printed line. By default, this adds a timestamp, but you may want to add hostname, process number, or more.

   format => sub { '['.localtime().'] '.$_[0] }
   format => sub { shift }   # no timestamp
   format => 'LONG'

The first parameter to format is the string to print; it is already translated and trailed by a newline. The second parameter is the text-domain (if known). The "LONG" format is equivalent to:

  my $t = strftime "%FT%T", gmtime;
  "[$t $$] $_[1] $_[0]"

format_reason => 'UPPERCASE'|'LOWERCASE'|'UCFIRST'|'IGNORE'|CODE

locale => LOCALE

mode => 'NORMAL'|'VERBOSE'|'ASSERT'|'DEBUG'|0..3

replace => BOOLEAN

Only used in combination with a FILENAME: throw away the old file if it exists. Probably you wish to append to existing information.

Use the LOCALE setting by default, which is LC_CTYPE or LC_ALL or LANG (in that order). If these contain a character-set which Perl understands, then that is used, otherwise silently ignored.

to => FILENAME|FILEHANDLE|OBJECT

You can either specify a FILENAME, which is opened in append mode with autoflush on. Or pass any kind of FILE-HANDLE or some OBJECT which implements a print() method. You probably want to have autoflush enabled on your FILE-HANDLES.

When cleaning-up the dispatcher, the file will only be closed in case of a FILENAME.

Accessors

Extends "Accessors" in Log::Report::Dispatcher.

$obj->filename(): Returns the name of the opened file, or undef in case this dispatcher was started from a file-handle or file-object.
$obj->format()
$obj->isDisabled(): Inherited, see "Accessors" in Log::Report::Dispatcher
$obj->mode(): Inherited, see "Accessors" in Log::Report::Dispatcher
$obj->name(): Inherited, see "Accessors" in Log::Report::Dispatcher
$obj->needs( [$reason] ): Inherited, see "Accessors" in Log::Report::Dispatcher
$obj->output()
$obj->type(): Inherited, see "Accessors" in Log::Report::Dispatcher

File maintenance

$obj->close(): Only when initiated with a FILENAME, the file will be closed. In any other case, nothing will be done.
$obj->rotate($filename): [1.00] Move the current file to $filename, and start a new file.

Logging
