## NAME
    [Log::Log4perl::Layout::PatternLayout::Multiline](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3ALayout%3A%3APatternLayout%3A%3AMultiline/markdown) - Multiline Pattern Layout

## SYNOPSIS
        use [Log::Log4perl::Layout::PatternLayout::Multiline](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3ALayout%3A%3APatternLayout%3A%3AMultiline/markdown);

        my $layout = [Log::Log4perl::Layout::PatternLayout::Multiline](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3ALayout%3A%3APatternLayout%3A%3AMultiline/markdown)->new(
            "%d (%F:%L)> %m");

## DESCRIPTION
    "[Log::Log4perl::Layout::PatternLayout::Multiline](https://www.chedong.com/phpMan.php/perldoc/Log%3A%3ALog4perl%3A%3ALayout%3A%3APatternLayout%3A%3AMultiline/markdown)" is a subclass of Log4perl's PatternLayout and
    is helpful if you send multiline messages to your appenders which appear as

        2007/04/04 23:59:01 This is
        a message with
        multiple lines

    and you want them to appear as

        2007/04/04 23:59:01 This is
        2007/04/04 23:59:01 a message with
        2007/04/04 23:59:01 multiple lines

    instead. This layout class simply splits up the incoming message into several chunks split by
    line breaks and renders them with PatternLayout just as if it had arrived in separate chunks in
    the first place.
