NAME

       Log::Agent::Channel::Handle - I/O handle logging channel for Log::Agent

SYNOPSIS

	require Log::Agent::Channel::Handle;

	my $driver = Log::Agent::Channel::Handle->make(
	    -prefix	=> "prefix",
	    -stampfmt	=> "own",
	    -showpid	=> 1,
	    -handle	=> *FILE,
	);

DESCRIPTION

       The handle channel performs logging to an already opened I/O handle, along with the necessary prefixing and stamping of the messages.

       The creation routine make() takes the following arguments:

       "-handle" => handle
	   Specifies the I/O handle to use.  It can be given as a GLOB reference, such as "*FILE", or as an "IO::Handle" object.

	   NOTE: Auto-flushing is not enabled on the handle.  Even when the channel is closed, the handle is left as-is: we simply stop sending
	   log messages to it.

       "-no_newline" => flag
	   When set to true, never append any "
" (on Unix) or "
" (on Windows) to log messages.

	   Internally, Log::Agent relies on the channel to delimit logged lines appropriately, so this flag is not used.  However, it might be
	   useful for "Log::Agent::Logger" users.

	   Default is false, meaning newline markers are systematically appended.

       "-no_prefixing" => flag
	   When set to true, disable the prefixing logic entirely, i.e. the following options are ignored completely: "-prefix", "-showpid",
	   "-no_ucfirst", "-stampfmt".

	   Default is false.

       "-no_ucfirst" => flag
	   When set to true, don't upper-case the first letter of the log message entry when there's no prefix inserted before the logged line.
	   When there is a prefix, a ":" character follows, and therefore the leading letter of the message should not be upper-cased anyway.

	   Default is false, meaning uppercasing is performed.

       "-prefix" => prefix
	   The application prefix string to prepend to messages.

       "-showpid" => flag
	   If set to true, the PID of the process will be appended within square brackets after the prefix, to all messages.

	   Default is false.

       "-stampfmt" => (name | CODE)
	   Specifies the time stamp format to use. By default, my "own" format is used.  See Log::Agent::Stamping for a description of the
	   available format names.

	   You may also specify a CODE ref: that routine will be called every time we need to compute a time stamp. It should not expect any
	   parameter, and should return a string.

CAVEAT

       Beware of chdir().  If your program uses chdir(), you should always specify logfiles by using absolute paths, otherwise you run the risk of
       having your relative paths become invalid: there is no anchoring done at the time you specify them.  This is especially true when
       configured for rotation, since the logfiles are recreated as needed and you might end up with many logfiles scattered throughout all the
       directories you chdir()ed to.
