Re: Re; Pdf of Manuals

[brentboylan]

When you try to open it in Adobe Reader (at least in XI) it will tell you to
download a Flash plugin to properly view the documents. Do this (it doesn't
take long) and then open the file again. You'll see all the documents in a
row across the page. Search in all the docs at once from the search box at
the top. Works great.

Re: MetronomeMark aligned to accidentals

Well, here's something rough which appears to do the trick.

The basic idea is that the function locates a PaperColumn that is related
to both our MetronomeMark grob and an AccidentalPlacement grob.  If it
finds it, it calculates the extent of all the accidentals and sets X-offset
based on this.

Hope this helps.  Let me know if you run into problems with it.

There are different types of expressions (music expressions, output
definition expressions, etc.), but not different types of variables.  You
don't have to declare/define a variable's type, they are dynamically typed.

Put another way, output definitions like \layout {...} or \midi {...} are
not the same thing as music expressions like { c4 d e f }.  None of these
are variables, they are expressions, but they can be assigned to a variable.  

You may find it easier to learn to fish by just doing some fishing, if you
know what I mean?

See the following which does what you describe.  The \omit line inserts but
does not display a grace note between the two key signatures, and the
\override line prevents the key cancellation from being shown.  

\version "2.18.0"

\relative f' {
  \key g \major
  \omit \grace s8
  \override Staff.KeyCancellation.stencil = ##f
  \key c \major
  c8 cis d dis e f fis g gis a ais b c
}

One problem is that if you want the g key signature to be shown at the
beginning of each line, as is customary, then you would need to do something
like this at the beginning of each line (ugh).  So it's not really a good
solution.  Another possibility might be to replace the c major stencil, but
that will not really be any better I don't think...

Hi Karol,

below the revised function.
'moreWhiteout' takes one optional and two normal arguments:
Specifying whether the stencil should be boxed (boolean), which grob
(string) and the values to extent the stencil. These values can be
given as simple pair, affecting only X-axis-extension or as list of
pairs, affecting X- and Y-axis-extent.
The boolean may be of some use for debugging, though it will affect
spacing! Perhaps I should delete it ...

Otherwise I did some clean up and made the function more robust.
Please test.

I think you're wrong.

Re: Understanding Lilypond language

[Harald Christiansen]

Hello David,

Many thanks for your reply.  :-)

I was giving the variable example as a kind of difficulty I have. I
appreciate the "fish" you are giving to me but I want to learn "how to
fish" :-)

For example you say
"Because \layout { ... } is not a music expression but rather an output
definition. Different type. "

and then later on:

"There are no typed variables."

In my mind these two do not work together ... for me there is some
understanding missing.

And yes I found the Lilypond Extending manual but that still doesn't
explain properly the Lilypond language itself.

Regards.

My apologies for poor statement of the question!  The above I am quite

I think your answer to my previous question about transposing cues 
will solve my problem with some work on my part.  The following 
modification of the documented example may or may not illustrate my 
need.  I actually now have an untransposed (concert pitch) 
clarinet part with cues that I want to make into a clarinet part where 
each section can be played on the clarinet that is easiest.

\version "2.19.3"

flute = \relative c'' {
  \key f \major
  \cueDuring #"clarinet" #DOWN {
R1 _\markup\tiny "clarinet"
c4 f e d
R1 _\markup\tiny "clarinet"
c4 f e d 
  }
}
\addQuote flute \flute 
clarinetA = \relative c'' {
  \key aes \major
  \transposition a
  aes4 bes c des
%  <>^\markup { muta in B\flat }
  \cueDuring flute #up R1 
}
clarinetB = \relative c'' {
  \key g \major
  \transposition bes
  d2 g,
  \cueDuring flute #up R1 
}
clarinet = { \clarinetA \transpose a bes \clarinetB } 
\addQuote "clarinet" \clarinet
<<
  \new Staff \with { instrumentName = #"Flute" }
\flute
  \new Staff \with { instrumentName = #"Cl (A)" }
\clarinet

The last flute cue is not transposed correctly which I guess 
is answered by your previous answer.

Re: Import, edit and export a Lilypond file using Python

[brentboylan]

If I understand what you are after, you want to produce an audio file for
each part (SATB) that individuals can use to practice at home with.

I have been preparing a lilypond file to do the same thing for the choir I
direct. It is evolving even now, but one of the key components came from
using  Frescobaldi    and the score wizard included:

 

In the 'Parts' tab of the score wizard, if you insert a 'Choir' instrument,
one of the settings on the right is 'Rehearsal MIDI files'. Checking that
box adds the following code to create a separate MIDI file for each part:

% Rehearsal MIDI files:
\book {
  \bookOutputSuffix "soprano"
  \score {
\rehearsalMidi "soprano" "soprano sax" \sopranoVerse
\midi { }
  }
}

\book {
  \bookOutputSuffix "alto"
  \score {
\rehearsalMidi "alto" "soprano sax" \altoVerse
\midi { }
  }
}

\book {
  \bookOutputSuffix "tenor"
  \score {
\rehearsalMidi "tenor" "tenor sax" \tenorVerse
\midi { }
  }
}

\book {
  \bookOutputSuffix "bass"
  \score {
\rehearsalMidi "bass" "tenor sax" \bassVerse
\midi { }
  }
}

This creates MIDI files with filenames that tag on whatever is in the
\bookOutputSuffix field (myChoirPiece-bass.mid for example.) While this is
just the individual parts, you could easily add in the accompaniment or
other parts for reference to be included in the MIDI output.

The way I am using this is by adding it to a template that I use whenever I
create a new SATB arrangement. I like to keep 'content' separate from
'presentation' as is popular in many styles of programming, so my
'presentation' file has the extra MIDI generating lines and my content.ly
file holds everything unique to the piece I am working on. I have an
explanation of what I'm doing on my  blog    but
it is a work in progress. I will post a new item in the forum here when I am
ready to share it, including the .ly template files.

Of course, my method does not involve importing MusicXML information but I
believe it could be done relatively easily, using the content.ly as the
target.

Re: Hyphen in a lyrics word

Hi Phil,

I don’t want to make this thread much longer as I got the answer I
needed, but here I have to disagree. It might depend on the language,
but I am not speaking of hyphens due to hyphenation but hyphens
separating words in non-broken text.

In German, I would say it’s not a matter of taste. You can not write
SBahn instead of S-Bahn or iPunkt instead of i-Punkt.

Concerning English, I am not so sure, but can you really write:
maneating shark instead of man-eating shark or
twentiethcentury painting instead of twentieth-century painting?

That’s the use-case I was talking about, not hyphenation to split syllables.

Cheers,

I'm afraid I've misled you here.  Although MetronomeMark layout object 
supposedly supports the break-alignable-interface, according to the IR, it 
seems not to behave in the same way as RehearsalMark and BarNumber layout 
objects.  Sorry about that; I should have checked more carefully before making 
the suggestion.

However, you may be able to obtain a satisfactory placing by overriding 
self-alignment-X, eg

\version "2.19.3"
{
  R1 |
  \override Score.MetronomeMark.self-alignment-X = -0.3
  \tempo "Tempo"
  
}

This offsets the metronome mark from its default position of 0 - centered on 
the left-most notehead.  Unfortunately the required value will depend on the 
string length provided to \tempo and the number of accidentals, so this is 
strictly a poor work-around.

Maybe someone else will have a better solution.

Yes, that's where I'm headed for, but it must be in a completely
automated way, from a MusicXML file...

The question is (probably better worded as) *how* would you create a .ly
file with a single voice from a file (MusicXML or .ly) containing
multiple voices, using a (Python) script...


I can't check right now, but I _assume_ that musicxml2ly will produce a 
file with a number of variables containing the music and a \score block.


Furthermore I assume your variables will always be the same (e.g. 
"sopranoMusic" or whatever).


Then you could
- run musicxml2ly on your xml file
- purge the \score block from it
  (check if that always comes last in the file,
   then it should be very easy)
- write different .ily ("include ly") files containing (only) different
  \score structures, one for each kind of output you want to have.
  (this should be done beforehand and only once)
- create different .ly files, one for each type of output.
  This should first include the generated and stripped conversion file
  and then the desired score block.
  creating these .ly files could be done programmatically by using a
  template file.

Doing all this with a Python script seems quite straightforward.
And I'm not sure whether you need to mangle the XML files first.

HTH

PS: Please always reply to the list or to all, so that everyone can 
share the discussion (I have already done this for the current message).




So for now, I' following David Kastrup's advice and working with the

Well, the point of MusicXML is doing manipulations as XML rather than
with regexps or similar.

Uh, XSLT scripts or something?

One can certainly also work well with LilyPond code itself, but when the
source of that LilyPond code is converted automatically from MusicXML
using musicxml2ly, it's likely somewhat clunky and unreliable to delve
in there as it will be missing distinctive marks and names and whatever.

Yes, that's where I'm headed for, but it must be in a completely 
automated way, from a MusicXML file...


The question is (probably better worded as) *how* would you create a .ly 
file with a single voice from a file (MusicXML or .ly) containing 
multiple voices, using a (Python) script...


So for now, I' following David Kastrup's advice and working with the

Import, edit and export a Lilypond file using Python

[Joachim Jablon]

Hello everyone,

I've asked a question on StackOverflow about Lilypond files and Python, 
and someone suggested that I ask the lilypond community directly.


For the long version, you can see the question here :
http://stackoverflow.com/questions/22883594/generating-pdf-midi-from-musicxml-using-python

For the short version :
I would like to import an existing Lilypond .ly file, remove some parts 
and export the resulting file as .ly/pdf/midi/mp3, using Python.
(in fact my input is a musicxml file but now I've discovered the 
musicxml2ly script so that's not a problem)
What would you suggest as the most appropriate tools (probably python 
libs) to do so ?


Thanks a lot,

So, yes, as you suggested, I should be able to :
1) Edit the XML using standard xml tools
2) make it a .ly file using the lilypond script
3) make it a beautiful partition using lilypond :)

I thought I would use a python lib that would manage the MusicXML part 
for me, but in the end, MusicXML is just XML, so I'll be able to do it 
myself.

Thanks, that should do fine as a workaround.

Does anyone else agree that the behavior I'm suggesting should be the default?

Manipulating LilyPond files is not trivial, and your description is not
at all useful for figuring out what "remove some parts" is even remotely
supposed to mean.

You might want to do your removal operation while still in MusicXML
using some standard XML manipulation tool, and only then convert to
LilyPond.

Re: Extra naturals in accidental-style teaching?

[Ariel Barton]

Thank you!

I think that what I want is not the forget style, but to have Lilypond
typeset everything in C major/A minor. I'd still sort of like to print
the true key signature; do you know if there's a way to print the D major
keysignature while it's in C? (\key d \major \key c \major produces an
error message unless I put something between the two key changes, \key d
\major s1 \key c \major makes my measure count off and also prints a
bunch of courtesy accidentals at the "key change" to C major; there
might be something I can do involving the "sharp=postitions" setting for
the "key-signature-interface" but I can't really figure out how Lilypond
wants me to phrase that.)

Thanks,
Ariel

Re: python 2.6 in GUB Re: LilyPond-Book on Windows

[Urs Liska]

There _is_ a "lilypond" "organization" on github already, created and owned by 
Janek.

We can easily fork the necessary repositories there and give all persons the 
necessary push access.

As to the merge question:
As Graham sais you shouldn't merge the request.
Rather add the respective fork as a remote to your local clone and pull the 
interesting branches there.
Then test and merge manually.

If I install lilypond on my Fedora 20 system using the version from the

that.


The installers from the Lilypond website are shipped with an older Python

Well, issue 1933

suggest that this is a bad idea.  Nothing substantially has changed
since then.  I'm currently trying to get the TEXINPUTS stuff integrated

course it is to be hoped that moving Python forward to 2.6 might make
that problem go away.  But it will take longer to figure that out.

Thanks Harm.

In SpanBar-Dynamics conflict I still prefer whiteout over 
DynamicText.extra-spacing-width = ##f. The only problem is that sometimes 
whiteout box does not cover the whole barline width. Function I'm asking for 
would allow to control the width of whiteout box.

BTW, In documentation for 2.19 it's written that default value for 
DynamicText.extra-spacing-width is '(+inf.0 . -inf.0), which is not true

Should you consider _what_ a bug?

There is a context called FretBoards that tends to work with grobs
called FretBoard.  Apparently this confuses you more than a context
called Voice that tends to work with grobs called NoteHead, Stem,
Accidental and so on.

There is not really a bug, but there might be a less than helpful naming
scheme.  Replace FretBoards with FretBoardStaff or FredBoardHolder in
your head and FretBoard with FretBoardItem and try reading the
documentation again with that distinction in mind.

Note that

\new FretBoards { \override FretBoard.whatever ... }

is equivalent to

\new FretBoards { \override Bottom.FretBoard.whatever ... }

and thus to

\new FretBoards { \override FretBoards.FretBoard.whatever ... }

The 2.16 syntax is probably more helpful in this case: there we have

\new FretBoards { \override FretBoard #'whatever ... }

equivalent to

\new FretBoards { \override Bottom.FretBoard #'whatever ... }

and

\new FretBoards { \override FretBoards.FretBoard #'whatever ... }


My original pitch at the new syntax was to have

\new FretBoards { \override FretBoard whatever ... }
\new FretBoards { \override Bottom.FretBoard whatever ... }
\new FretBoards { \override FretBoards.FretBoard whatever ... }

but people hated that.  And it's somewhat uglier for function arguments.

You can actually at the current moment write this alternatively (since
it is a part of backward compatibility with the old syntax), but it does
not transfer to functions like \overrideProperty and so on.

It is a dynamically typed language.  Not much programming in the
language itself, but a Scheme layer caters for that and provides all the
types.

The command line processes an input file, and certain things like
top-level music or scores cause actions.

No.  Neither is the above.  Both place a sequential music structure into
the respective variables.  Use

\void \displayMusic \allLyrics
\void \displayMusic \foo

to see what's in there.

Because \layout { ... } is not a music expression but rather an output
definition.  Different type.

There are no typed variables.  Types are associated with expressions
rather than variables: that's what using a dynamically typed language
like Scheme is about.  So there is no point in declaring a variable.
Its type is determined by what you place in there.

Check out the red manual.

Re: Question about FretBoards context

[Pierre Perol-Schneider]

Thanks Fedrico, but still I don't get it.
The FretBoards reference page says (
http://www.lilypond.org/doc/v2.18/Documentation/internals/fretboards) :
"This context creates the following layout object(s): FretBoard, etc."
So ?
Should I consider this as a bug ?

Understanding Lilypond language

[Harald Christiansen]

Hello,

Is there a manual for the lilypond language itself ?

I don't get it ... is it a programming language ... a macro expander ...
all of the above ?

I cannot build a mental model of how it works.

For example, let's take variables. I take the notation reference, I look
at the index and I see several entries.

One entry specifies:

3.1.5 File structure
[...]

A variable, such as

foo = { c4 d e d }

So far so good.

Another entry:

3.3.2 Different editions from one source
[...]
Using variables

allLyrics = \lyricmode {King of glo -- ry }

Is this just a macro substitution ?

But then in one of my own I have to declare

myLayout = \layout { ___
