I wanted to get bar lines after each sub-meter of a compound meter, and

Thanks to David and Jan-Peter, I was able to change their
doubleBarlinesAfterTimeSig engraver to achieve this effect. I still have
a little more work to do since some of the moment variables currently
have fixed values.

The engraver works well as seen in the code below. Again, I do not
really understand the significance of why, for example time-signature is
set to '() although it does not change in the engraver. Also, when I
tried to change the variable last-fraction to last-bnum, it resulted in
a syntax error, even after changing the #f to #0. Perhaps someone may
know the answer to this.

Here is the modified engraver. Currently, it sets up timings of 3/4, 5/4
and 2/4 and puts a double bar at the end of the three measures. Also
notice how the double notes are split and tied across the bar lines.
Pretty cool, I would say.

I think you must have gotten this here:  http://www.mail-archive.com/lilypond-user%40gnu.org/msg78039.html

It says it's written by Jan-Peter, based on something I wrote.  What that something could be, I don't know anymore :)
