[logback-dev] Parameterized logging

[Pavel Bortnovskiy]

Hello:

I am a new subscriber to this list, so please forgive me if these 
questions have already been asked and answered.

Being quite experienced with log4j, migrating to Logback would probably be 
a relatively easy exercise. However, while reading the manual, I have a 
few questions, which might be best addressed to the developers, rather 
than the users.

1) using parameterized logging instead of wrapping the log statment in a 
conditional isEnabled, is very convenient, however I wonder whether there 
is an implementation of printf
function (or whether there are plans to do so). 
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Formatter.html#format(java.lang.String, 
java.lang.Object...) 
Implementation of log statements with such functionality and a variable 
arg list would be fairly trivial, but I found no references to such in 
Logback Javadocs, FAQ or search engine queries.

2) If the answer to (1) is NO, then is there an easy way to extend Logback 
to incorporate such functions?

3) the need to migrate to Logback arose when we started to look into 
modularizing our application with OSGi Apache Felix. What OSGi bundles of 
Logback/SLF4J would you recommend?

Your response is greatly appreciated.

Regards,

Pavel Bortnovskiy.
