There is no standard way for color coding messages.

For some terminals this is done with escape codes, which I don’t believe that e.g. Eclipse supports´in its Console window, and I do not expect that e.g. Chainsaw og Lilith support these.

Subject: [logback-user] Coloring log messages

Hi all

I am quire fascinated about the powers and ease logback gives to its users. I am experimenting with various options it offers like appenders, encoders etc.Recently I though if we could color code the log messages for various logging levels. For example, red for Error, Green for Trace etc. I have these options with me but none seemed to work as desired:

- Extending <code> ClassicConverter </code> & overriding <code> convert(ILoggingEvent) </code> as given in the documentation chapter 6 for Creating a custom conversion specifier. This way, I could color the level using <code> event.getLevel() </code> but could not color the entire log statement as per my wish.

- On the page http://logback.qos.ch/demo.html it is written that "You can color log statements with markers. Markers are part of the SLF4J API." But I could not find any example for that.

- I tried extending <code> RollingFileAppender </code> and in the <code> subAppend </code> I tried to access <code>quirtWriter qs </code> as one could do in earlier versions, but now <code> qs </code> is not visible.

Please guide for the appropriate way of doing it as well as provide some directions / examples. 

Thanks & Regards
