argument 3.  Expecting music, found #>
   c1
 \startTextSpan \lyricmode { ral -- len -- tan -- do }"

upon compiling. And I don’t know what my mistake would be…

It's the last line before %%% EXAMPLES where you enter some strange
recursion.  You probably should first save the old value of
\startTextSpan in some differently named variable and use that.  But
really: reusing an existing command name is a bad idea to start with.



I think it’s eventually a good idea to replace the definition of 
\startTextSpan, firstly because it’s the most convenient sort of 
interface for this custom function. And secondly: _Any_ sensible use of 
text spanners now requires a quite complicated \override, even most 
common cases:

%%%
\relative {
  \override TextSpanner.bound-details.left.text = "rit."
  b'1\startTextSpan
  e,\stopTextSpan
}
%%%
Being able to input the same as
%%%
\relative {
  b'1\startTextSpan \lyricmode { rit. }
  e,\stopTextSpan
}
%%%
would be a huge improvement IMO.
I think it’s not often that one only needs a text to end the spanner, so
\startTextSpan \lyricmode { "" -- "back to normal" }
would be acceptable.

Drawback: it’s impossible to provide backward compatibility then, isn’t it?

But you were right and storing the default value in an extra variable 
solved the problem. I overlooked that I was introducing a recursion 
instead of redefining a variable. Thanks.

‘new text-spanner’ development

[Simon Albrecht]

Hello,

as the other thread was becoming a monster, I start up a new one.
I’ve now got a version of text-span-spread.ly, as I call it, and it 
compiles now. However, a new problem appeared, which I assume has to do 
with variable scope and seems to be over my head: The first call to the 
\startTextSpan music function sets the texts for _all_ the subsequent 
calls. Even more suspiciously, the tweak to font-shape in line 725 
(ugh…) is also applied to all these instances.
I’m sorry to call for help so soon again, but I just don’t have enough 
experience and background to troubleshoot this with any degree of 
efficiency. Any hints are welcome! :-)

Well, I don't know who is responsible for this particular idiom
encountered frequently in here, but the following open-coded loop is
both opaque and inefficient (namely O(n^2) as _appending_ to a list is
an O(n) operation):

extractLyricEventInfo =
#(define-scheme-function (lst) (ly:music?)
   "Given a music expression @var{lst}, return a list of pairs.  The
@code{car} of each pair is the text of any @code{LyricEvent}, and the
@code{cdr} is a boolean representing presence or absence of a hyphen
associated with that @code{LyricEvent}."
   ;; TODO: include duration info, skips?
   (let ((grist (extract-named-music lst '(LyricEvent
 (let mill ((grist grist) (flour '()))
   (if (null? grist)
   flour
   (let* ((text (ly:music-property (car grist) 'text))
  (hyphen (extract-named-music (car grist) 'HyphenEvent))
  (hyphen? (not (null? hyphen
 (mill (cdr grist)
   (append flour (list (cons text hyphen?)

Open-coded, you are much better off writing:

   (let ((grist (extract-named-music lst '(LyricEvent
 (let mill ((grist grist) (flour '()))
   (if (null? grist)
   (reverse! flour)
   (let* ((text (ly:music-property (car grist) 'text))
  (hyphen (extract-named-music (car grist) 'HyphenEvent))
  (hyphen? (not (null? hyphen
 (mill (cdr grist)
   (cons (cons text hyphen?) flour))

Since cons is O(1) and the final reverse! O(n) is only done once, you
arrive at O(n) for all.  But why open-code in the first place?

  (map (lambda (elt)
 (let* ((text (ly:music-property elt 'text))
(hyphen (extract-named-music elt 'HyphenEvent))
(hyphen? (pair? hyphen)))
(cons text hyphen)))
   (extract-named-music lst 'LyricEvent)))

For something that is one-on-one, this is far more transparent.  And
even for something that is one-to-some (namely resulting in possibly 0,
1, or more elements), (append-map (lambda (elt) ...) ...) tends to be
much clearer.

Compiling Nenuvar Editions (was: Re: lilypond-user Digest, Vol 154, Issue 123)

Hi Michael,

please always edit the subject line when replying to e-mail digests. Or 
just turn off digest mode – I find (using Thunderbird’s filtering and

Did you clone/copy the entire repository? IIUC, you took only the 
Messiah folder and copied it to ~/Documents on your machine, right? This 
will (a) not work because there are \includes in there pointing outside 
the directory; and (b) you’d need to change the path you pass to make.

So you _might_ try just running
make
inside the Messiah directory,
(or ‘make ~/Documents/Messiah’ from anywhere)
but it’s unlikely to work.

double time signature with single-digit

C 3 with both mensural sign and number centered around the central noteline.

How about this (based on LSR #725):

%
%% see http://lsr.di.unimi.it/LSR/Item?id=725
%% see also http://lilypond.org/doc/v2.18/Documentation/snippets/rhythms

\relative c' {
   \override Score.TimeSignature.stencil =
   #(double-time-signature  "timesig.mensural44" "3")
   \time 3/4
   c8 b c d e f g4 g g g4 a8 g f e d2. \bar "|."
}
%



Adjust the \fontsize value to taste (0 means default size, BTW).

Best,
Abraham

Since this seems to be more complicated than anticipated,

here a full rundown of what I did.

1. I'm on Linux with make installed. Not sure about other OS'es. You
 also need a commandline (bash in my case)
2. I've downloaded the whole zip from https://github.com/nsceaux/nenuvar
 As of yesterday it was almost 8MB in size.
3. I've extracted this zip. That created a directory nenuvar-master in
 the current directory. I cd'd into it (cd nenuvar-master)
 [it is completely irrelevant where in your filesystem this located
 as everything below nenuvar-master is self contained -- in other words
 nenuvar-master is freely relocateable]
4. Inside .../nenuvar-master I issued
 make Haendel/Oratorio/Messiah
 and that created said score (with some warnings)

All references to files are relative to .../nenuvar-master

I'm pretty sure compiling the score requires LP 2.19.x to compile
out-of-the-box. I'm using 2.19.27. I haven't tested 2.18.2 but would not
be surprised if that fails.

As I already wrote in another mail, you could get a complete list of
valid make targets when you issue (inside ../nenuvar-master)
grep ":" Makefile | grep -v .PHONY | sed -e "s/:.*//"

When you do not get a rather lengthy list (in my case 396 lines) with
targets then you are either not in the correct directory or have
downloaded the wrong file. Or something completely different ;)

Last not least the score requires the scorlatti font.
Either get it from http://fonts.openlilylib.org/
or remove the \paper block in common/common.ily lines 18-22


HTH,
Michael

PS: Please trim your mails in that you copy only the stuff into your
mail, that is somewhat relevant to your issue. There is no need to
include msg regarding textspanner when you ask about Compiling
Nenuvar Editions.

No, just that I did at one point of time work on that.

Hi Simon,

this may give you a starting point:

\version "2.19.27"

test =
#(define-scheme-function (mus) (ly:music?)
   (ly:book-process
 (ly:make-book-part (list (ly:make-score mus)))
 $defaultpaper
 $defaultlayout
 (ly:parser-output-name)))

m = { c'4 }

\test \m


Shoot, I did find a flaw: I need a \bookpart {}, not a \book, but it 
needs to contain a \paper block. How can I do that?

If you have a rather recent version, you can write the following:

\version "2.19.25"

tir = \rightHandFinger \etc
apo = \tweak digit-names ##("P" "I" "M" "A" "X") \rightHandFinger \etc

{ c'\tir2 f' \apo4 }

If it's less recent, it's a few lines more.

After figuring out that the $defaultpaper variable contains an empty

How about this (based on LSR #725):

Adjust the \fontsize value to taste (0 means default size, BTW).

Problems with text alignment

[Mark Veltzer]

Hello all,

I have a problem and a solution to it which does is not very stable.

My problem is that I want music sheets to be followed by their text. Since
these are
songs I arrange the text in several columns to save space. The text is RTL
(hebrew in this case).

What is the problem? I want the columns to be aligned to the right on the
screen.
I can do it but the only way I found to do it is by inserting bogus not
deterministic
number of empty columns and using 'fill-line'.

My question is this: Is there a better solution?

Attached are the input and output files.

The input file contains a more detailed description of the problem.


Cheers,
   Mark
%{

This example shows the problem of aligning text to the right in lilypond.
Without the following two empty 'right-column' entires this example
would show up with one column aligned to the right of the screen
and the other to the left (internally alight to the right)
with lots of space in between.

I am not aware of any other means to get at the result that you get
from this example which does not involved the two 'right-column' entires.

This is an unstable solution since the number of 'right-column' entries
involved is a function of the page width.

Is there a way in lilypond for a more straight forward solution to this
problem?

Re: Compiling Nenuvar Editions

[Michael Dykes]

Please forgive my ignorance but I have updated to Lily 2.19.27-1 and 
downloaded the Scorlatti file. However, not sure for lack of a better 
way of wording it "where to install it"/where to put the font files and 
which folder(s) I need to out where. Again forgive my ignorance here.

 Subject: Re: Compiling Nenuvar Editions 
Message-ID: <1946334.bza5fid5Jh@hamiller> Content-Type: text/plain; 
charset="us-ascii" Since this seems to be more complicated than 
anticipated,

I have now downloaded his entire zip file and am using the code
suggested by Simon (I think) which is:

thedoctor818@TARDIS:~/Documents/nenuvar-master/Haendel$ m

and keep getting the error message:

make: *** No rule to make target 'Haendel/Oratorio/Messiah'.  Stop.

I am trying this in the directory: Documents/Haendel

I also tried this in Documents/Haendel/Oratorio/Messiah but to no avail.

here a full rundown of what I did.

1. I'm on Linux with make installed. Not sure about other OS'es. You
  also need a commandline (bash in my case)
2. I've downloaded the whole zip from https://github.com/nsceaux/nenuvar
  As of yesterday it was almost 8MB in size.
3. I've extracted this zip. That created a directory nenuvar-master in
  the current directory. I cd'd into it (cd nenuvar-master)
  [it is completely irrelevant where in your filesystem this located
  as everything below nenuvar-master is self contained -- in other words
  nenuvar-master is freely relocateable]
4. Inside .../nenuvar-master I issued
  make Haendel/Oratorio/Messiah
  and that created said score (with some warnings)

All references to files are relative to .../nenuvar-master

I'm pretty sure compiling the score requires LP 2.19.x to compile
out-of-the-box. I'm using 2.19.27. I haven't tested 2.18.2 but would not
be surprised if that fails.

As I already wrote in another mail, you could get a complete list of
valid make targets when you issue (inside ../nenuvar-master)
grep ":" Makefile | grep -v .PHONY | sed -e "s/:.*//"

When you do not get a rather lengthy list (in my case 396 lines) with
targets then you are either not in the correct directory or have
downloaded the wrong file. Or something completely different ;)

Last not least the score requires the scorlatti font.
Either get it from http://fonts.openlilylib.org/
or remove the \paper block in common/common.ily lines 18-22


HTH,
Michael

PS: Please trim your mails in that you copy only the stuff into your
mail, that is somewhat relevant to your issue. There is no need to
include msg regarding textspanner when you ask about Compiling

Did you read the documentation at fonts.openlilylib.org? There's a section
that tells you precisely where to put them (and make sure you install all
the scorlatti-XX files, not just one of them.

Pass the finger number as a parameter:

But I've never seen upper case letters used to indicate stroke 
fingering, and there must be several hundred commercially engraved 
guitar scores in my collection. For lower case stroke fingering, the 
following is much simpler to enter and easier to read (you can't use 
lower case p or a, as p is a dynamic indication and a is a note name, so 
I use upper case for the shortcuts):


P=\rightHandFinger #1
I=\rightHandFinger #2
M=\rightHandFinger #3
A=\rightHandFinger #4

{ c'\P f'\I }

Is the attached more what you want? It's tricky to tell as I'm not
familiar with editing RTL in emacs. (I changed the 3 As to XYZ to
distinguish the paragraphs.)
