extends LogEventPatternConverter

Highlight pattern converter. Formats the result of a pattern using a color appropriate for the Level in the LogEvent.

For example:

You can define custom colors for each Level:

 %highlight{%d{ ISO8601 } [%t] %-5level: %msg%n%throwable}{FATAL=red, ERROR=red, WARN=yellow, INFO=green, DEBUG=cyan,
 TRACE=black}
 

You can use a predefined style:

 %highlight{%d{ ISO8601 } [%t] %-5level: %msg%n%throwable}{STYLE=Log4j}
 
The available predefined styles are:

You can use whitespace around the comma and equal sign. The names in values MUST come from the AnsiEscape enum, case is normalized to upper-case internally.
