I also added the following paragraph to the docs: Please note that the right most segment in a logger name is never abbreviated, even if its length is longer than the <em>length</em> option. Other segments may be shortened to at most a single character but are never removed. Ceki Gulcu wrote:

Assume the conversion specifier "%logger{3}" and logger name "mainPackage.sub.sample.Bar". This will result in "m.s.s.Bar" which is the shortest string containing representations for all package names, plus the full name of the rightmost segment (the class name). The package names are represented by a single letter.

Does that make sense?

I cant clearly understand the documentation of the conversion word %c

I thought %c{10} will always return string at maximum length 10 but its obviously not true. In the JUnit test "hello.world" is abbreviated "h.world" while length set to 1.

Seems its a maximum length of the string before the last dot?!?

Thanks
