Re: tocItem as \mark

[David Sumbler]

Thanks, that's brilliant, and it will be a very useful template for me
for creating functions in the future.

Since my original post, I had experimented some more and thought I had
succeeded in getting the result I wanted, basically doing what your
function does, but as 2 separate calls.  My solution, of course, was
not nearly so neat as wrapping it all together.

Unfortunately, there is a problem with a couple of the TOC items.
 There is already a fermata Mark over the preceding barline, so I get a
"Two simultaneous mark events, junking this one" warning.  The same
problem, of course, arises with your function which combines the Mark
and the tocItem.  I tried using

allowSimultaneousMarks = { \cadenzaOn \once \omit Score.TimeSignature
\time 1/16 s16 \bar "" \cadenzaOff \once \omit Score.TimeSignature }

which I have found useful in the past, but for some reason it messed up
the vertical alignment of notes in the following bar.

I ended up by doing a rather make-shift thing of putting the titles in
the score as markups using

s1*0^\tweak X-offset #-9 \tweak Y-offset #10 -\markup {                
  \fontsize #2 \bold "Title" }

before the first note of the top line of the score, and also in other
parts with a tag so that it only prints in the parts, not the score.

This is rather unsatisfactory, because the offsets need adjusting for
each song and probably also for each part.  Fortunately in this
particular case there is only one other instrument that needs a
separate part.

Can you see a way of combining the titles as a RehearsalMark with a
fermata over the barline?
