But I suppose the point of a > bars-per-line-engraver is the freedom to do just that. I've been experimenting with implementing the above, but so far I'm unable to set 'line-break-permission to #f within the engraver without getting errors (though there's no problem setting it in a \context block). In the interests of making the user interface friendlier, I added a feature for specifying repeats. You can now write something like this: \consists #(bars-per-line-engraver '(5 7*5 1 3*3)) instead of \consists #(bars-per-line-engraver '(5 7 7 7 7 7 1 3 3 3)) I don't know if there could be potential issues using the asterisk, since it's reserved for rhythmic input.. If there is, I could use another character, or do something like: '(7 (7 . 5) 1 (3 . 3)) though I rather like the asterisks. Anyway, I hope this helps! -David
