OTOH: is it possible to have LilyPond trigger an external program
*after* the PDF has been created? I recall getting an answer for a hook
that works at the very end of the engraving process (this should allow
me to write out data into a log file that has only been generated during
the after-line-breaking stage). Is there such a hook to execute after
the PDF has been written?

Something like this should be possible:

$ PATH=~/your_wrappers:$PATH
$ cat ~/your_wrappers/lilypond
#!/bin/sh

/usr/bin/lilypond "$@"
echo Finished, do something
$ lilypond xxx
...
Finished, do something
$

Or use a Makefile, you can look at my workflow if you like:
  http://aspodata.se/git/musik/bin/
  http://aspodata.se/git/musik/include/


Much simpler . Put

#(system "program parameters ...") 

after a book, at the very end of the file or wherever you want to 
execute an external program.


Thanks, this is exactly what I need. I wouldn't have thought it is so 
simple.
With that I can trigger any post-processing script from within the 
LilyPond document :-)

mkvideo, sync to recorded audio

[Christian Alpen]

Hi,

once again I have a question concerning generating video with 
mkvideo-lily-diff:


I want to synchronize the video to a manually recorded audio track with 
rubato and tempo variations.
Somewhere I read about how to generate an extra file containing these 
tempo informations (using extra software
to create scores from contemporary and not yet notated music) and how to 
use it to extract these information for

mkvideo generating the video.

The problem is: After googling a lot around I cannot find this guide again.
So I'm looking for help on how this is done or, if anyone knows or 
remembers, a link to this guide.


Can anyone help me with this?

Thanks a lot,

Christian

Staves?
You only have one staff actually explicitly defined in your file, and 
you're not using the <<  >> construct which would then produce 
simultaneous staves :)


That's all you need.

I didn't actually test your file but when you have

\set doubleSlurs = ##t

you can achieve the contrary effect with

\set doubleSlurs = ##f

Hi again,

If you're going to attach an ly file that is fine, however can I ask: in 
addition to just attaching a full score with a brief question, could you 
please at least


* either isolate a section of your input file and place it in the body 
of your message with the question;

* or tell us to look at line numbers xx-yy along with your question?

It's frustratingly time consuming to have to compile, then compile 
again, each time, with each post...the entire input file...and then try 
and scroll through the file, eyeball the appropriate location in the 
entire score file where the question may apply to, then begin to answer 
your question...thank you kindly.



As for double slurs, it's pretty straight-forward.

http://lilypond.org/doc/v2.19/Documentation/notation/expressive-marks-as-curves#slurs

\relative c' {
  \set doubleSlurs = ##t
  4(   )
}

Then use ##f when you're finished, etc.

retrying in and out polyphony

That code does not compile.

The octave marks go on the other-side,   -->  c''2

Also, what are you trying to do with the S's? Single note? Tied?


\relative c'
{ c''2  ~\< c\!  }


That's how you terminate a hairpin :)

Does this help?

Ah yes, indeed you can use spacer notes for that situation, now I 
understand.

Also, make sure you use the << >> as well.

There's a few different ways you can "stretch out" the hairpins, here is 
just one example:


\version "2.19.80"
% spacer rests needed for a cresc + decres. on the same note as below
 \relative c'
{
  \override Hairpin.minimum-length = #10
f1
<< f1 { s4 s4\< s4\> s4\! } >>

}

see attached.

So strange, now that I re-compiled it seems to have all the staves correct.
Bizarre. When I first downloaded it, the score only had one staff declared,
and everything else outside.

It does seem aligned now...

Tie shape

[Pieter Terpstra]

Dear people,
Another question.
Trying to change the shape of the tie in such a way that the c note becomes 
free from the tie overlap.
The \Shape command works on the lowest tie but not on the next?
To add the \Shape command a second time makes no difference.

Here is the example:
\score {
  \relative c' {
g'16\rest 
  \shape #'((0 . 0) (0 . -1) (0 . -1) (0 . 0)) Tie
  \set tieWaitForNote = ##t
  b,~
  \shape #'((-3 . 0) (0 . -3) (0 . -3) (0 . 0)) Tie
  d~ g~ s8 c ~ s4 
  }
}

Kindly,

   Peter

If you can't get it to work with the shape, maybe you'd get some results

Re: Tie shape

[Andrew Bernard]

Hi Pieter,

Apparently ties, although they look almost identical to slurs, use a
different type of machinery internally to produce their shape, and the
\shape functions only partially work. I do not know why the code is
different, but I suppose lilypond 'just grew' and that's how it is. Most
people end up having to use TieColumn techniques in this case.

Others more learned  than I in lilypond internals will no doubt be able to
explain this better.

Ties are not really very perfect in lilypond, and there was an effort to
fix them up, but I understand that project came to end end due to time and
resource matters on the part of the developer.
