Hi all,
I am working on a Scheme function and would like to check if I have found the
best solution for a specific subpart. Somehow it looks more complicated than
necessary.
The function needs to test if each element of a given list is a (sub)list with
exactly two elements. So
'((1 2)(3 4))
Hi Urs,
it doesn't make too much sense to first collect the whole list and
then check for membership of #f. It'd be more reasonable to stop
iteration once any of the preconditions isn't met. You could achieve
this by using a recursive function like below (you could make it
more terse by using if
Hi,
I almost don’t know any Scheme but I think this could be done with a
map, a fold, and some function composition. In Haskell, you would do this:
validate = foldr () True . map ((== 2) . length)
validateShort = and . map ((== 2) . length)
The function and is a shortcut

Hi David,
I wasn't aware that SRFI-1 is included in lilypond. Is there any
documentation about which libs/packages are included in lilypond?

I'm making that exercise for my students now** and found... the first group
of eighths after \unHideNotes is missing its beam. It omits 8th-note flags,
and it draws the stems as if it's going to beam them, but... no beam.
** Thanks, Pierre, for reminding me about \hideNotes!

I don't think that it's documented (and it's not all that much more).
But of course you can
Hi all,
is there already a function that converts a string 4. to the fraction
'3/8', or the other-way round?
Maybe it's helpful to know that the string is intended for use with
\note, e g
\note #4. #UP
and the fraction is intended for use with \set Timing.baseMoment, e g
\set
if the work is open source, can LilyJAZZ be integrated with Lilypond?

Hi Nick,
you'll find more noteheads here:

This snippet by Victor Adan shows how to use them in a score:

Folks, every discourse community has implicit assumptions, and the music
community is no different both in its jargon and in its score conventions.
Guitar transposes down the octave unless the score states otherwise.
Contrabass and contrabassoon sound an octave lower than written. Piccolos

Hi!
Is there any easy way in version 2.18.2 to get a custos at the end of
the (visible) notation in mensural or petrucci voice context?
Without twidling with forcing linebreak hiding staff notes other
objects. That is; having to manufacture a fucking lot of code
