[slf4j-user] feature request: LOG.debugFormat("This is a number %f", someFloat)

[Thomas Oellrich]

It would also be possible to only support %s, not the full range of
formatting options, just like Google Guava's Precondition class does
it:

http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/base/Preconditions.html

I, too, would welcome such an addition since it's cumbersome having to
remember to use %s when using Preconditions and String.printf, but {}
when logging in SLF4J. A better name, though, might be Logger.debugf
just as used by JBOSS' Logging API.

Cheers,

Thomas
