             Summary: [PatternLayout] Add an ANSI option to %message
                 Key: LOG4J2-1459
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1459
             Project: Log4j 2
          Issue Type: New Feature
            Reporter: Gary Gregory
            Assignee: Gary Gregory
             Fix For: 2.7


For {{PatternLayout}}: Add an ANSI option to {{message}} so you can say {{%message\{ansi\}}} and allow ANSI escape syntax in your log even messages.

For example:

Using styles defined in the configuration:

{code:xml}
       <PatternLayout>
         <Pattern>%message{ansi}{WarningStyle=red,bold KeyStyle=white ValueStyle=blue}%n</Pattern>
      </PatternLayout>
{code}
{code:java}
logger.error("@|WarningStyle Warning!|@ Pants on @|WarningStyle fire!|@");
{code}

Using hard-coded styles:
{code:java}
logger.error("@|red Warning!|@ Pants on @|blue fire!|@");
{code}

The {{"@|Style Text|@"}} is from JANSI but the markers can be user defined using {{BeginToken}} and {{EndToken}}:

{code:xml}
       <PatternLayout>
         <Pattern>%message{ansi}{BeginToken=@| EndToken=|@ WarningStyle=red,bold KeyStyle=white ValueStyle=blue}%n</Pattern>
      </PatternLayout>
{code}
