Logda logging bridges

NOTE: Logda's API is not final yet. Although the library is fairly funcional, this is still beta-quality code. Do not rely on it for production code just yet. Feedback is very welcome!

What is it?

Logda is currently a Log4j logging bridge with support for Java 8 Lamdas.

Features

• Log4j equivalent api (Means same method signatures)
• Less code overhead for adaptive logging

How do I use it?

Assuming you are using Log4j today

1. Checkout this projekt and run mvn install in the root of this projekt

2. Add the following dependency to your Maven projekt

   <dependency>
      <groupId>dk.mwl.logda</groupId>
      <artifactId>logda-log4j</artifactId>
      <version>1.0-SNAPSHOT</version>
   </dependency>

3. Start replacing your org.apache.log4j.Logger and org.apache.log4j.LoggerFactory imports with dk.mwl.logda.Logger and dk.mwl.logda.LoggerFactory

4. Start logging with

   logger.debug(() -> "Queue size=" + queue.size())

As this example is using Java 8's Lambda expressions it will only calculate the queue size if debug logging is enable for this context.
