Hi, I'm trying to use this component - aware that it is in early dev stages but with the intention of contributing back fixes. For example I have made some changes to allow handling of date patterns with a timezone e..g %d{yyyy-MM-dd HH:mm:ss.SSS,UTC} I have also added parsers for %thread and %logger. I'm coming unstuck with a few types of pattern e.g. %d{yyyy-MM-dd HH:mm:ss.SSS %-5logger %msg Will parse "2013-06-07 10:00:00.999 ERROR rest of my log message" But will fail to parse "2013-06-07 10:00:00.999 INFO rest of my log message" (reducing the two spaces after INFO to one makes it parseable) And also anything like %logger{0} seems to confuse matching no end. IN debug mode it looks like the date pattern is considered to be the whole pattern and it fails to see the } at the end of %d{....}: 08:46:01.510 [main] DEBUG ch.qos.logback.decoder.Decoder - date = 2013-06-07 05:03:28.853 08:46:01.514 [main] ERROR ch.qos.logback.decoder.DateParser - java.lang.IllegalArgumentException: Illegal pattern character 'U' 08:46:01.514 [main] DEBUG ch.qos.logback.decoder.Decoder - level = INFO 08:46:01.515 [main] DEBUG ch.qos.logback.decoder.Decoder - BUG!!

Can anyone advise on how these last two could be fixed? Also is logback-decoder abandoned or just waiting for volunteers? If its abandoned are there any alternatives?
