-----------------------------------
Summary: Pattern To Drop First X Package Parts
Key: LOG4J2-621
URL: https://issues.apache.org/jira/browse/LOG4J2-621
Project: Log4j 2
Issue Type: Wish
Components: Layouts
Affects Versions: 2.0-rc1
Reporter: Lee Theobald
Priority: Trivial
Currently you can have a pattern that will print out the last X parts of you
package. So if my package was `uk.co.ltheobald.foo.bar`, then using
`%logger{2}` will print `foo.bar`. But when I have a number of different
package levels, this becomes less useful (in my opinion).
What I'd find more useful is the inverse where I can ditch the first X parts.
Something like `%logger{-3}` for example. That way I'd end up with:
`uk.co.ltheobald.Main logging` as `Main`
`uk.co.ltheobald.foo.MyClass` logging as `foo.MyClass`
`uk.co.ltheobald.foo.bar.MyOtherClass` logging as `foo.bar.MyOtherClass`
Removing from the start of the logger name allows me to consistently trim off
package names that I know are always the same.
I'll see if I can produce a code example for this if I get time but I wanted to
log it in the meanwhile.
