with this, it is also annoying to have to remember to change syntax when
logging errors (cannot use paramatized strings). It would be nice if things
were more consistent.</font>

Correct. As you stated, the logback API sits on top of SLF4J. There are
no plans <br>
to change that.<br>

You do realize that the SLF4J API already supports parameterized logging
up to 2 <br>
parameters? With an SLF4J logger you can write:<br>
<br>
Logger logger = LoggerFactory.getLogger(Wombat.class);<br>
Integer t;<br>
Integer oldT;<br>
Integer expectedT;<br>
<br>
logger.debug("Some message.");<br>
logger.debug("Temperature set to {}", t);<br>
logger.debug("Temperature set to {}. Old temperature was {}.",
t, oldT);<br>
<br>
However, SLF4J does not support 3 or more parameters. So, you could not
write:<br>
<br>
logger.debug("new={}, old={}, expected={}", t, oldT, expectedT);<br>
<br>
You would have to write:<br>
<br>
logger.debug("new={}, old={}, expected={}", new Integer[] {t,
oldT, expectedT});<br>
<br>
I believe that compared to the slight inconvenience above, breaking <br>
compatibility is a more serious concern.<br>

You might also want to check out the slf4j-migrator [1] which may help
with your <br>
migration efforts, when and if you decide to migrate to SLF4J.<br>
