Thanks. Now I see that it didn't _seem_ to work because I ran the wrong LilyPond version :-[

Hi again,

sorry to have to insist on perhaps basic questions.
As it is the function now works as I want, but not in 2.16.
From the versions I have available to test it works with 2.17.6 onwards and not with 2.17.3 and less.
Somehow I suspect the change between 2.17.3 and .4

My best bet is that

  #{ $@(map (lambda (s) #{ $colorizeDir $s #}) debug-direction-grob-list) #})

in the mapList function is the offending piece of code.

Is there a way to write this so it compiles both with 2.16.2 and with current versions?
If that's not possible how would I achieve the same with 2.16.2 (I can do a conditional include if necessary)?

Please refer to the attached version of the function.

TIA
Urs
