Re: Expansion of score for different format

[Carl Peterson]

Premature sending...

As I was saying, the problem with the below code is that it prints the first verse, but it only prints the first verse. I also simplified the code so that instead of just passing lyrics in the list structure, each list element is one or more Lyrics blocks.

I've made a little bit of progress: I've changed the code to:

(if (not (null? lyrics))

#{ $(car lyrics)

$(make-my-scores parser location (cdr lyrics))

#}

)

seqVerses =

#(define-void-function (parser location up down title composer passage meter lyricist copyright lyrics)

(ly:music? ly:music? string? string? string? scheme? scheme? scheme? list?)

Okay, so I've been fairly successful in implementing and tweaking. I'm working  on the complementary function, to output a regular score with stacked verses for book layout. Here is my re-arrangement: 

If I leave out #(make-my-scores parser location lyrics) in the main seqVerses function, I get the music just fine. However, when I add this, I get guile errors. What am I missing here? I'm sure there's something obvious that just isn't coming to mind.

Thanks,

Yes, I do something similar. This might help get you started:

I think you're better off writing two separate functions instead of a
big if/else block: one for one score with multiple verses and another,
like the above, for multiple scores each with one verse.
