Thank you for following up on my request at stackoverflow.com to open this. As it stands the abbreviator will also support a pattern like \{1.1.} which would print "o.a.commons.Foo". Unfortunately if the package name was "org.apache.logging.log4j.core.Foo" it would print "o.a.logging.log4j.core.Foo" so it doesn't really accomplish what you want.  I would suggest that modifying the Pattern Abbreviator to accept a pattern like \{1.2*} which would mean abbreviate everything except the last 2 "words" to a single character would be more useful.

> The following are my favorite patterns
> {quote}%c\{2} - which displays the corresponding number of rightmost logger name components. So a logger with a name like "org.apache.commons.Foo" is displayed as "commons.Foo".
> {quote}
> and
> {quote}%c\{1.} - which abbreviates the name based on the pattern. So a logger with a name like "org.apache.commons.Foo" is displayed as "o.a.c.Foo".
> {quote}
> Is there a way to combine the two. I want to abbreviate the name of all logger components except the 2 rightmost. Such that "org.apache.commons.Foo" is displayed as "o.a.commons.Foo".
