New question #252424 on Sikuli:
https://answers.launchpad.net/sikuli/+question/252424

A previous thread that is closest to answering my current question is:
    https://answers.launchpad.net/sikuli/+question/248604
in which RaiMan suggest the usage of a setSikuliXLogCallback

I searched the net for setSikuliXLogCallback, but the only hit I got was that thread.  Hence this question/plea for more detail.

I recently started looking into Sikuli using IDE first, then I moved onto using standalone Jython, and then finally had the courage to venture into using Ruby, which is the primary language of my test framework.
I was pleasantly surprised how easy and great the interface was. Kudos to RaiMan and contributors on this great tool.

Now, onto my question...
I can redirect the java output to a single log file via Debug.setLogFile(log_file). 
My test framework, however, uses Log4R which direct the log output to multiple files as well as the console. 
Ideally I would like to redirect the logging requests to my logger to do it's thing, so that I can get all the output like:
[LOG] CLICK on L(27,10)@S(0)[0,0 1440x900]
in the standard log files.

I kind-a implemented a workaround that does this as follows:
1. I put in a one-line callback patch in the native_exception_protect() method  in the sikulix.rb  file, like this:
            m.bind(self).call(*args)  # previous existing line
            SikuliX4Ruby.post_region_callback(m) if SikuliX4Ruby.respond_to?(:post_region_callback)  # line added

2.  Redirected the java logs to a temp file first, by defining and calling the following:
module SikuliLib
   def self.log_file=(log_file)
    @@log_file = log_file
    Debug.setLogFile(log_file)
end

3.  Captured the original logoutput and logged it via myLogger as such:
module SikuliX4Ruby
  def self.post_region_callback(method = nil, obj =nil)
    file = SikuliLib.log_file
    File.readlines(file).each { |line| myLogger.info(line.chomp) } if File.size?(file)
    FileUtils.rm file
  end
end

My workaround does the trick for now, but I'm not happy about the fact that I had to copy and patch the sikulix.rb file.
I would rather not muck with original SikuliX distribution files and use a callback that is officially supported, if there is one (The previous question thread hinted that there might be one already.)
