Wow, I really like this solution. I’ve been sitting the signatures in the 
normal location, but this is far more clear. Thanks!

I've done this some month ago in the german forum
http://www.lilypondforum.de/index.php?topic=2127.msg11763#msg11763
Without account you'll not able to see the image, so I attached it
below, but the code should be available.

I was too tired to write documentation about it and didn't return to
it, maybe I should put it in LSR.
Note the beat-structure is hard-coded to '() for now. If this gives
problems, please shout.

HTH,

Thank you very much Paul, for this and your previous message. I think it’s 
going to be really helpful.

Hi again,  I’d suggest looking at snippets in the LSR, searching for "time 
signature", if you haven’t yet, .  This one looks like it might be helpful:

You’ll find it in ly/music-functions-init.ly

What is the proper way of programmatically generating markup?

[Matt Hood]

Hi everyone,

So I’m writing a function that reimplements the ‘\compoundMeter’ command with 
an Orff-style time signature, whereby the denominator of the signature is a 
note head (as opposed to a number), e.g. 4/4 = 4/crotchet, 9/8 = 
3/dotted-crotchet, 15/16+2/4 = 5/dotted-quaver + 2/crotchet. I’ve been able to 
implement the first two cases, i.e. no additive signatures,  but I’d like to 
make the third example work.

**My first question is: does anyone know where can I find the source (scm or 
otherwise) for \compoundMeter? I can’t find it in the ‘share/scm’ folder. I 
feel like it would be helpful to reference.**

My attempts to make this work have involved trying to generate the markup using 
foreach loops, that crawl through a list of lists that might look like:

(  (3 3 (ly:make-duration 3 1))   (4 (ly:make-duration 2))  )

which would be equal to: (9+9/16)+(4/4). All elements except for the last of 
each loop are numerators, while the last is the denominator.

-

This is the scheme code doing the work (not finished, but the basics should 
work?). The list-of-lists is referred to as ‘durs':

\version “2.18.2"
...
(markup
(#:line
  ( for-each
   (lambda (x) 
(markup "+")
( #:center-column 
 
 ;; Numerator Markup. The list supplied to the for-each loop doesn’t 
contain the duration. [“(cdr (reverse x))”]
 (#:line  
   (for-each 
(lambda (y) 
 (
  ( markup "+") 
  (#:number (number->string y) )
 )
)
(cdr (reverse x))
   )
 )

;; Denominator markup.
(#:note-by-number 
 (ly:duration-log (car (reverse x))) 
 (ly:duration-dot-count (car (reverse x))) 
 DOWN
)
   
   )
  )
  durs
 )
)
)

This haphazard collection of markup needs to somehow fit into:

\override Score.TimeSignature #'text =

which accepts ‘markup’, singular, only. 

This throws errors such as:
warning: type check for `stencil' failed; value `#' must 
be of type `stencil'

--

**So my second question is: How do I programmatically generate markup from 
information taken from a list, and then put it into a single markup variable?**

Any help at all would be greatly appreciated.
