Writing multiline log messages into single line in NLog

I prefer to avoid writing single log message into several lines. Doing that allows me to analyze my logs using console tools like grep more efficiently.
While it is easy to meet this convention in custom log messages, user has to solve this problem for text which is put by several Nlog layout renderers, for example exception stacktrace renderer. To solve this problem I use replace layout wrapper. Take a look to a following nlog config:

	<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<variable name="brief" value="${longdate} | ${level} | ${logger} | ${message} | ${exception:format=ToString}"/>
	<variable name="verbose" value="${longdate} | ${processid} | ${processname} | ${threadid} | ${level} | ${logger} | ${message} | ${exception:format=ToString}"/>
	<variable name="verbose_inline" value="${replace:inner=${verbose}:searchFor=\\r\\n|\\n:replaceWith=->:regex=true}"/>
	<targets>
	<target name="file" xsi:type="File" layout="${verbose_inline}" fileName="${basedir}/logs/mcserver_${shortdate}.log" />
	<target name="console" xsi:type="ColoredConsole" layout="${brief}" />
	</targets>
	<rules>
	<logger name="*" minlevel="Trace" writeTo="file" />
	<logger name="*" minlevel="Trace" writeTo="console" />
	</rules>
	</nlog>

In this example I use my custom verbose_inline layout that replaces all newlines to "->" string. After that I can easily sort out statistics for e.g. specific exception using grep command like:

grep -i 'System.NullReferenceException' *.log >nullref.txt
