NAME

Log::Dispatch::Atom - Log to an atom feed.

VERSION

This document describes Log::Dispatch::Atom version 0.01

SYNOPSIS

    use Log::Dispatch::Atom;

    my $log = Log::Dispatch::Atom->new(
        name      => 'foo',
        min_level => 'debug',
        file      => 'file.atom'
    );
    $log->log_message( level => 'error', message => 'A problem happened' );
    $log->log_message( level => 'debug', message => 'Got Here' );

DESCRIPTION

This class implements logging backed by an Atom feed so that you can subscribe to the errors produced by your application.

You should not use this object directly, but should manage it via a Log::Dispatch object.

IMPLEMENTATION NOTES

In order to safely write to the log file, the entire file must be locked each time that an entry is logged. This probably makes it unsuitable for high volume log files.

The log file is opened and closed on each call to log_message().

METHODS

new()

Takes a hash of arguments. Returns a new Log::Dispatch::Atom object. The following parameters are used:

name [mandatory]

The name of the logging object.

min_level [mandatory]

The minimum logging level this object will accept. See Log::Dispatch for more information.

max_level [optional]

The maximum logging level this object will accept. See Log::Dispatch for more information. The default is the highest possible level (ie: no maximum).

file [mandatory]

Specifies the location of the file to read/write the feed from.

feed_id [optional]

Specifies the identity of the feed itself. Normally, this should be set to the published URI of the feed.

If not specified, it will be omitted, which is in violation of the Atom specification. For more information, see http://www.atomenabled.org/developers/syndication/#requiredFeedElements.

feed_title [optional]

The title of the feed. This should probably be set to the name of your application.

If not specified, it will be omitted, which is in violation of the Atom specification. For more information, see http://www.atomenabled.org/developers/syndication/#requiredFeedElements.

XXX This should probably just use the name parameter.

log_message()

Takes a hash of arguments. Has no return value. The following parameters are used.

message [mandatory]

The actual log message.

level [mandatory]

The level of the message. See Log::Dispatch for a full list.

DEPENDENCIES

XML::Atom version 0.15.

This module uses flock() to the lock the feed file whilst it's writing, so your version of Perl will need support for that.
