[logback-user] log4j StringMatchFilter porting to logback

[Fabio Erculiani]

Ok now I got that part.
Still, it's very unclear to me how I could match a string declared in
logback.xml (even regexp would be fine) using AbstractMatcherFilter,
without either pulling in Groovy or Janino. Could you be more clear?
It doesn't seem possible to me, and the manual is a bit vague.

Thanks,
