You will find this in the documentation for version 2.18.2 in chapter
1.4.1 long repeats: Your third and fourth alternative should be
something like

\set Score.repeatCommands = #'((volta "3, 4") end-repeat)

I installed ActivePerl (windows pc).
"Perl -v " runs correctly and it shows "This is perl 5, version " etc.

Now tried to do:

LilyPond MusicXML export

2016-11-10 Thread Menu Jacques
Hello Folks,

A newbie question : does there exist something simililar to \displayMusic, that 
would display the structure of \score blocks? This could be a starting point 
for such an export.

And also : has it been considered/studied to perform a two-pass compilation of 
LP, with the first pass creating some internal form as Scheme data (hence the 
question above) and the second pass creating the grobs from the latter? Such a 
separation of concerns could also help I guess, even though it might involve 
much work.

I'm using Strawberry Perl (http://strawberryperl.com/) and have just tried
perl .\tidy_midi.pl LottiAminAgnus-midi.ly  > LottiAminAgnus.out2.ly

Comparing the result with the original LottiAminAgnus.out.ly shows no
differences except for line endings.

David,

I wish you all the very best for your future endeavours. I thank you most
sincerely for your immensely significant and important contribution to
making lilypond the exceptional tool for engraving that it is. Having tried
myself to study the source code and remaining baffled despite decades of
software development experience, I am in awe at your ability to comprehend
and extend this complex code base, for the benefit of us all. It will be
difficult if not impossible for anybody to fill your shoes. I extend my
immense gratitude to you for your tireless pursuit of software excellence.

All the best from Down Under!

And thanks, David, for your part in changing the course of my life, for 
a while at least. It was discovering LilyPond some years ago which 
reminded me of the compositions I still had around, handwritten in 
ballpoint.


I started experimenting with engraving these old compositions, then 
started writing more, some of which I have performed to some (very 
localised) acclaim. I have also used LilyPond to prepare arrangements of 
music to use with people with cognitive disorders such as Alzheimer's. 
Since then, I have had to all but give up music again, and move into an 
altogether different field, but LilyPond's influence may have reached 
further than either yourself or the other developers realise.


Do stay around in any capacity if you can!

With very best wishes,

I you send me the file I can have a look to see if I can adjust the

Multiple optional arguments

2016-11-10 Thread Urs Liska
Hi all,

I would like to have two optional arguments in a music function. My
current approach fails, and I don't know if I'm doing anything wrong or
if I'm trying the wrong thing in the first place.

I have created an interface with two optional and one mandatory
argument. I thought that this should work as long as they differ in
type. However, it only works properly when both arguments are missing or
if the second arg is missing (and of course if all are provided).
However, when the first one is missing the function raises a syntax error.

Is this because LilyPond can't properly discern the two types or is it
generally impossible to use two such optional arguments in sequence? And
if the latter, how can I achieve the effect otherwise? What I want is
that the function uses a global variable but sets it to a new value
before in the case one is provided by the user.

Thanks
Urs

%%

\version "2.19.50"

test =
#(define-void-function (fund dur ratio)
   ((ly:pitch?) (ly:duration?) fraction?)
   (if (ly:pitch? fund)
   (format "Pitch found: ~a" fund))
   (display fund)(newline)
   (display dur)(newline)
   (display ratio)(newline))


% regular invocation
\test b, 4 3/2

% both optional args missing (works)
\test 4/3

% second optional arg missing (works)
\test b, 5/4

I think what you need to do is to make the type test for the first one
to be something like (lambda (a) (or (type1? a) (type2? a))) and then
check which type you actually got inside the function body.

When all else fails, read the manual, in this case the extension guide.


2.2.2 Scheme function usage
---

Scheme functions can be called pretty much anywhere where a Scheme
expression starting with ‘#’ can be written.  You call a scheme function
from LilyPond by writing its name preceded by ‘\’, followed by its
arguments.  Once an optional argument predicate does not match an
argument, LilyPond skips this and all following optional arguments,
replacing them with their specified default, and ‘backs up’ the argument
that did not match to the place of the next mandatory argument.  Since
the backed up argument needs to go somewhere, optional arguments are not
actually considered optional unless followed by a mandatory argument.

the ly file you provide had not been created by midi2ly.py (lilypond's MIDI to
ly converter)
However Karl's Perl script is working specifically with files created by
midi2ly.py, not with ly files in general.

Find attached your midi files converted by midi2ly.py and after that with
tiny_midi.pl

Kind regards,

Re: Stepping down and moving on

Hi David,

Congratulations on your new position!  Let me echo everyone in thanking 
you for all your invaluable work on LilyPond.  Needless to say, it is in 
much better shape today because of your efforts and skills.  We will 
miss you as a full-time contributor (and also your humorous asides and 
metaphors) but hope you will continue to contribute as you are able.


All my best,
-Paul

Hi folks and team,

while I haven't really occupied an official function in LilyPond
development, it's hard to deny that I have effectively functioned as
acting chief architect and vetter (with a rather mottled performance).

Partly in connection with a drop of my productivity particularly this
year, the amount of financial support for my work from members of the
LilyPond community went down from overall survivable to disastrous.  Of
course this is bitter for those of you that did contribute in
significant amounts to my subsistence but I have to be moving on.

I have accepted a full-time development (and team management) position
with another company.  Due to their project and team expansion plans,
I will be starting already in December.

This employment is in another city.  I'll be travelling back and forth
weekly for the foreseeable future.  While I might be working on some
LilyPond side projects interesting to me occasionally, I will not be
able to do any serious amound of coordination or other activity
involving me with LilyPond's community.

As my communication style has proven to be a somewhat mixed blessing for
the purpose of attracting long-term developers, I expect that this may
help in the long run for finding a different balance of areas LilyPond
is getting worked on.

During his tenure as LilyPond leader, Graham has demonstrated that even
without a central technical lead there is a lot of potential to focus
the resources of people willing to work on and expand LilyPond and we
have been continuing to reap the results of his talent for organizing
people into useful teams even though I have not really figured out how
to fill gaps in the various teams and tools managing LilyPond's
infrastructure to offset the "natural" amounts of fluctuation.

I'll try seeing through the release of 2.20 in the little time remaining
to me both before and after starting my job.  My main worry is the
current comparative amount of instability with regard to font handling,
and my main bad taste is that 2.20.1 will not be able to support
Guile 2: there is no way that anything deserving the label of "stable"
and including Guile 2 will come about in the rest of my tenure.

There are also several half-completed features that are a nuisance.
I do not expect to be able to to a significant amount of work on them in
the foreseeable future.

Once consequence, of course, is that my requirement for funding is over.
I am greatly thankful to the people who have enabled me to keep working
on LilyPond as long as I did, but what remains in my bank account, in
spite of being quite less than what I started with when working on
LilyPond, is sufficient to tide me over the time to my first paycheck.

So I would ask you to cancel any regular bank payments you might still
have in place as of December: I don't see that I will have a reasonable
chance at returning a tangible value for them.

Thanks for making me stay in the pond as long as I did!

Re: Alignment of instrument names

Unfortunately you can’t. There already is a request for that feature in 
our issue tracker, but it hasn’t been implemented yet.



The code (minimal, I hope)


Not quite minimal. Minimal would be


\version "2.19.49"
\new Staff \with {
  instrumentName = "Violoncello e Contrabbasso"
} { 1 }


You do have to find an appropriate indent value by trial and error. 
However, you /can/ override instrument names’ self-alignment, if you like:



\version "2.19.49"
<<
  \new Staff \with {
instrumentName = "Flauti"
  } { 1 }
  \new Staff \with {
instrumentName = "Violoncello e Contrabbasso"
  } { 1 }
>>
\layout {
  \context {
\Staff
\override InstrumentName.self-alignment-X = #LEFT
  }
  indent = 50
}
%%

Ultimately, I’d certainly advise you to use
instrumentName = \markup {
  \center-column {
"Violoncello e"
"Contrabbasso"
  }
}
or something similar, to avoid the need for such a huge indent.

Best, Simon

Hm. Shouldn't it be possible to work around this restriction with 
something in the line of:


\version "2.19.49"

\paper {
  indent =
  #(let* ((layout '()) ;; <=== How to get the default layout here?!
  (text-props (ly:output-def-lookup layout 'text-font-defaults))
  (stil (ly:text-interface::interpret-markup layout text-props 
(markup "Supercalifragilisticexpialidocious")))

  (xext (ly:stencil-extent stil X))
  (width (- (cdr xext) (car xext
width)
}

\new Staff \with {
  instrumentName = "Supercalifragilisticexpialidocious"
} { c'1 \break c'1 }

The goal being to adjust the indent to fit the largest instrumentName 
(manually selected and entered before any content is inserted). The 
above code will not work, though, because I don't know how to get some 
layout object at this point...

Any hints?


Cheers,
Alexander

Well, there's the long and the short answer.

The short answer is simply send your proposed plain text to
the bug-list (that's  and someone will
pick it up, vet it, add any necessary formatting and guide 
it through the updating procedure.

The long answer (that's 'long' in the sense of more work for
you, but also more rewarding!) is to read the section on
doc work in the Contributors' Guide:
http://lilypond.org/doc/v2.19/Documentation/contributor/documentation-work
and work from there.  You'll get plenty of help, should you
need it.

Dear David,

I have nothing to add to what others have written here. But I want to
repeat it from my side: Thank you so much for your work on LilyPond!
Thank you for new functionality, for cleaner code, for easier input
syntax, for leading discussions with insightful contributions and
LilyPond facts and for the help for so many on this list!

I was kind of shocked when I read the mail subject from your address.
But I am convinced that it is a good decision for your finances and your
future - I feared it would happen earlier. I wish you a good start in
your new position. Hopefully, we will see you from time to time on these
lists.

Cordially,

Sure, we've gotten into polemical tiffs from time to time, but it has
always been clear that you are motivated by good intentions and that you
invest substantial consideration in what you say, and possess substantial

Dynamically outputting \books

2016-11-10 Thread Morten Lemvigh
Hi,

I am trying to create a procedure to create rehearsal midi files for each
voice of a choir piece. In order to do that I need to be able to
dynamically create \book blocks (one for each voice). Is that possible? I
have tried to have a music function output it like:

rehearsalMidi =
#(define-music-function
  (parser location)
  ()
#{ \book { .. }  #})

Is there some way to dynamically create book blocks?

Use define-scheme-function instead?  Not sure which LilyPond version is
required to actually have the books interpreted correctly when
encountered in the main text.

I think 
https://git.openlilylib.org/bfsc/kayser/blob/karlsruhe/includes/lib/engrave.ily 
does what you need, but I'm not sure if it's easily understandable (although I 
think or well commented), especially without the code of the other included 
files.

ahhh My apologies, you're totally right, I completely forgot it!

Thanks a lot for the conversion, it's a very good starting point!!!

Have you tried Frescobaldi's score wizard or template facilities? I use 
them frequently for your specific purpose, giving me voice tracks with 
the track voice highlighted and the others at a lower dynamic. I have 
also used the various MIDI properties such as pan position to isolate a 
voice on the left, e.g., with the remainder on the right.


Cheers,
Colin

Ties over multiple chords

2016-11-10 Thread Mojca Miklavec
Hello,

I don't know how to explain in proper terms what I want to achieve,
but I hope that it will be clear from the example below (I would be
grateful for a proper English term for this as well :).

I wrote the same thing twice. The second alternative works, but looks
ugly to me. I would like to use the first alternative (which is a bit
of cheating), but ties don't work properly there, most likely lilypond
has problems interpreting where the tie should point to.

Is there any better workaround?

\version "2.19.30"
\language "deutsch"

melody = \fixed c' {
  \time 2/4
  \key b \major

  % first alternative: this doesn't work
  << {f'2~} {s8 d'4.~} {s4 b4~} {s4. g8} >> |
  4. r8 |

  << {f'2~} {s8 es'4.~} {s4 a4~} {s4. g8} >> |
  4. r8 |

  % second alternative: this works
  f'8~ 8~ 8~ 8~ |
  4. r8 |

  f'8~ 8~ ~ 8~ |
  4. r8 |
}

\new PianoStaff <<
  \new Voice = "melody" {
\melody
  }
>>

(I could cheat with slurs, but I have no clue how to use them in this example.)

Thank you,
Mojca
