Re: Lyric word engraver bug

[Simon Albrecht]

Hello David,

many thanks for the proposed solution. For what I can see now, it works fine.
And sorry for wrongly attributing authorship – no idea how I came to do that. Anyway, I corrected it now.
Best regards,
Simon

OK, I think I may have solved it.  Fingers crossed.

The problem occurs when the callback which creates a stencil for the hyphen creates nothing.  Now why that would be the case I couldn't say.  After all, a hyphen does appear!  (I wonder if that is a bug.)

Anyway, your example and mine compiles nicely with a simple change from the > operator to >=  in a function from your file lyric-word.ily (as I've done below)

#(define (compress-pair syl-a hyphen syl-b threshold)

   (let* ((hyphen-sten (ly:lyric-hyphen::print hyphen))

          (hyphen-ex

           (if (ly:stencil? hyphen-sten)

               (ly:stencil-extent hyphen-sten X)

               (cons (/ threshold -2) (/ threshold 2)))))

     (if (>= (interval-length hyphen-ex) threshold) ;; now greater-than-or-equal-to

         '() ; no compression--DO NOTHING!

         

Let me know if you run into any problems with this change.
