[jira] [Updated] (LOG4J2-621) Pattern To Drop First X Package Parts
[ https://issues.apache.org/jira/browse/LOG4J2-621?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lee Theobald updated LOG4J2-621:
--------------------------------
Description:
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.
