Hi,

regarding your mail-adress I suppose you typeset a piece from Sylvius
Leopold Weiss, copying an old transkription. From the image likely:
lute-tablature to guitar-notation.

If that's true, there would be no reason to exactly follow this
transkription. It is not the original anyway.

So I'd like to second Simon.

Though, my guess may be wrong. Afaik, S.L.Weiss never used harmonics ...

Cheers,
  Harm

Hi Thomas Morley!,

I’m typesetting a piece of Fernando Sor from a facsimile?/first?/19th 
century?/early edition 
(http://hz.imslp.info/files/imglnks/usimg/8/8c/IMSLP470312-PMLP93616-Sor_op.60.pdf).
  He uses various notations to indicate harmonics.  I’m well aware of the 
“modern” ways to indicate harmonics as well as their equivalents in LilyPond.  
I know the great flexibility of LilyPond and I’m convinced that it is possible 
to typeset even less common forms of notations.

I still would like to know how to achieve a dotted semicircle but it’s probably 
a matter of PostScript rather than LilyPond.  Unfortunately I’m not very 
proficient with PostScript and so far I haven’t found a solution in various 
internet researches. 

Thanks for your help!
Sylvius

Hi Sylvius,

I knew everybody would discourage you and suggest modern harmonic notation!
Anyway, I can do the postscript for you. Give me a couple of days. Although
it can be said that some performers stumble over old notations, I quite
like them, especially in the 17-18c works I engrave and play.

  \score { \music }


A couple of things to keep in mind.  In LilyPond, \postscript does not 
have any bounds or outline.  That is why you were seeing overlap with 
other things.  You will need to use \with-dimensions (or \with-outline) 
to explicitly define the bounds (or outline) so that LilyPond can know 
how to move things around.


The dash pattern here is a little more complicated, since I wanted to 
demonstrate how you can get rounded dots instead of boxy dashes.  
Otherwise, something like `[0.2] 0 setdash` (without setting the line 
cap) would have been sufficient to create an even dash the size of the 
line width, resulting in boxy "dots".


Finally, based on the transcription you linked, the lower arc wraps 
around the fingering number.  Note that in my example, I am "lying" 
about the true dimensions of the arc so that LilyPond will permit 
overlap of the vertical bounds.

Re: dotted semicircle indicating harmonics

[Pierre Perol-Schneider]

Hi All,

I'm not sure that a poscript would be ideal.
I'm thinking about a pattern markup command that would do :

\markup{
  \combine
  \null
  \combine
  \concat { \null \hspace #5 "." }
  \combine
  \rotate #(* 1 (/ 90 7)) \concat { \null \hspace #5 "." }
  \combine
  \rotate #(* 2 (/ 90 7)) \concat { \null \hspace #5 "." }
  \combine
  \rotate #(* 3 (/ 90 7)) \concat { \null \hspace #5 "." }
  \combine
  \rotate #(* 4 (/ 90 7)) \concat { \null \hspace #5 "." }
  \combine
  \rotate #(* 5 (/ 90 7)) \concat { \null \hspace #5 "." }
  \combine
  \rotate #(* 6 (/ 90 7)) \concat { \null \hspace #5 "." }
  \combine
  \rotate #(* 7 (/ 90 7)) \concat { \null \hspace #5 "." }
  \null
}

etc.
(Here it shows a 90° circled pattern with 7 dots (".") with radius 5)

My attempt is limited by my Scheme knowledge -- so not working -- but here
it goes:

%circled-pattern
#(define-markup-command
  (circled-pattern layout props radius long nbr arg)
  (number? number? number? string?)
  (let*
   ((elmt (/ 360 long))
(rep (- nbr (- nbr 1)))
(the-form
 (markup
(#:combine
 (#:null)
 (#:combine
   (#:concat (#:null #:hspace radius arg
   (fold
(lambda (i prev)
  (#:combine
   (#:rotate
(* rep (/ long nbr))
(#:concat (#:null #:hspace radius arg
prev)
'()
(iota nbr)
(#:null)
   (interpret-markup layout props
 (markup the-form

%% Test (markup a 90° cricled pattern with radius 5 and 7 dots) :
\markup\circled-pattern #5 #90 #7 "."

I think it'd be fun to have such pattern to add to the LSR.
Any idea to make it work ?
TIA, Cheers,

Pierre

Re: Custom bar numbering format

Hi David,

please read more carefully: the explanations in the manual are for that 
which Kyle said he can already do independently. Combining the two is 
the issue, which requires an approach like the one Noeck proposed.

I'm trying to get Lilypond to replicate the way that I number scores
personally.

When I number my own scores, the bars that get numbers are

1) The first bar of every staff/system
2) Every 10 bars Regardless of location

I can do these two things independently, but am having problems getting
them to work together.  The biggest problem I have is that
Score.barNumberVisibility doesn't seem to record its own position in the
system.  Does anyone have an idea of how I could accomplish this?

Bar numbers can be typeset at regular intervals instead of just at
the beginning of every line.  To do this the default behavior must be
overridden to permit bar numbers to be printed at places other than the
start of a line.  This is controlled by the ‘break-visibility’ property
of ‘BarNumber’.  This takes three values which may be set to ‘#t’ or
‘#f’ to specify whether the corresponding bar number is visible or not.
The order of the three values is ‘end of line visible’, ‘middle of line
visible’, ‘beginning of line visible’.  In the following example bar
numbers are printed at all possible places:

  \relative c' {
\override Score.BarNumber.break-visibility = ##(#t #t #t)
\set Score.currentBarNumber = #11
% Permit first bar number to be printed
\bar ""
c1 | c | c | c |
\break
c1 | c | c | c |
  }
  [image src="lilypond/5f/lily-65039a1d.png" alt="[image of music]" text="image 
of music"]


Selected Snippets
.

_Printing the bar number for the first measure_

By default, the first bar number in a score is suppressed if it is
less than or equal to ‘1’.  By setting ‘barNumberVisibility’ to
‘all-bar-numbers-visible’, any bar number can be printed for the first
measure and all subsequent measures.  Note that an empty bar line must
be inserted before the first note for this to work.

  \layout {
indent = 0
ragged-right = ##t
  }
  
  \relative c' {

\set Score.barNumberVisibility = #all-bar-numbers-visible
\bar ""
c1 | d | e | f \break
g1 | e | d | c
  }
  [image src="lilypond/ad/lily-527f7481.png" alt="[image of music]" text="image 
of music"]

_Printing bar numbers at regular intervals_

Bar numbers can be printed at regular intervals by setting the
property ‘barNumberVisibility’.  Here the bar numbers are printed every
two measures except at the end of the line.

  \relative c' {
\override Score.BarNumber.break-visibility = #end-of-line-invisible
\set Score.currentBarNumber = #11
% Permit first bar number to be printed
\bar ""
% Print a bar number every second measure
\set Score.barNumberVisibility = #(every-nth-bar-number-visible 2)
c1 | c | c | c | c
\break
c1 | c | c | c | c
  }
  [image src="lilypond/25/lily-572e320e.png" alt="[image of music]" text="image 
of music"]

_Printing bar numbers with changing regular intervals_

The bar number interval can be changed by changing the context
function ‘{set-bar-number-visibility}’.

  \relative c' {
\override Score.BarNumber.break-visibility = #end-of-line-invisible
\context Score \applyContext #(set-bar-number-visibility 4)
\repeat unfold 10 c'1
\context Score \applyContext #(set-bar-number-visibility 2)
\repeat unfold 10 c

Ok, the examples in the manual may not actually be the best here since
they just happen to have a number at the start of all lines in the
relevant examples.  So I thought this was already the case.  This seems
actually tricky to do since the algorithmic bar number visibility
(defaulting to everything being visible) is applied independently of the
line-break-based visibility (defaulting to only show line numbers at the
start of the line) and either only have the power to _remove_ line
numbers rather than to add them.

So this would likely require preparing a stencil in an unpure/pure
container that commits suicide when not at a line break or not of the
right kind.

Align above "current" staff

[Urs Liska]

Hi all,

I want a music function to produce an ossia staff. The NR states that in 
order to place that above alignAboveContext should be used:


\new Staff = "main" \relative {
  c''4 b d c
  <<
{ c4 b d c }

\new Staff \with {
  \remove "Time_signature_engraver"
  alignAboveContext = #"main"
  \magnifyStaff #2/3
  firstClef = ##f
}
{ e4 d f e }
  >>
  c4 b c2
}

But is that also possible when I  (or my music-function) doesn't know 
the staff's name - or if it is explicitly named at all?

I am using Lilypond Version 2.18.2-1

I don't think I have ever managed to get this to work with Preview, and my

Re: Custom bar numbering format

[Noeck]

Dear Kyle,

please reply to the list directly.

> why does it print the bar numbers as such? 

It will print the bar numbers at each beginning of a line by default
BarNumber.break-visibility is set to begin-of-line-visible
That means all other bar lines in the middle and at the end of a staff
line have not bar number.

What the extra voice does, is this:
It is silent and at the beginning of each 10th bar, it changes the bar
number visibility to visible (unless it is the end of a staff line). But
only \once, that means only for this point in time. All other times
print bar numbers as the default (described above) says.

So in short the rules are now:
1. bar numbers only at the beginning of a staff line
2. change the rules to "at the beginning and in the middle of a staff
line" at every 10th bar.

Cheers,
Joram

Well, not sure actually, since it's problematic with 0, 1 , -1.
So how about :

%circled-pattern
#(define-markup-command
  (circled-pattern layout props radius angle num arg)
  (number? number? number? string?)
  (let* ((rep (- (abs num) 1))
  (the-form

   (markup (#:null))
   (iota (1+ rep)
 (interpret-markup layout props the-form)))

testOne = \markup "."
testTwo = \markup { \rotate #45 "!" }

\markup\circled-pattern #5 #180 #15 \testOne

Also to avoid the 360° misscount :

%circled-pattern
#(define-markup-command
  (circled-pattern layout props radius angle num arg)
  (number? number? number? string?)
  (let* ((rep (if (eq? angle 360)(abs num)(- (abs num) 1)))

(if (eq? (abs num) 1) (markup arg)
(markup

  (fold
   (lambda (i prev)
(markup
 (#:combine
  (#:rotate
   (* i (/ angle rep))
   (#:concat (#:null #:hspace radius arg)))
  prev)))
   (markup (#:null))
   (iota (1+ rep)
 (interpret-markup layout props the-form)))

testOne = \markup "."
testTwo = \markup \with-color #red "!"

\markup\circled-pattern #5 #180 #15 \testOne

You can use \applyContext for getting it before you initiate your own

The ability to click on notes and lyrics in the preview screen, and 
have the exact point highlighted in the corresponding Lilypond file 
was so enormously useful, that the loss of this function has become 
a great barrier to efficient use of the program.


I am using Lilypond Version 2.18.2-1
Apple Macintosh System 10.11.6
Apple Preview Version 8.1 (877.7)
I don't think I have ever managed to get this to work with Preview, 
and my first attempt was way before Sierra, so I'm not sure it has 
ever worked. (10.11 is El Capitan, by the way ...)
I have used Acrobat Reader instead, but Preview updates the page when 
you rebuild, with Acrobat doesn't, so it's not ideal. Others have 
mentioned Skim, perhaps that's something to take a look at.




Today I had the chance to try my father's Mac.
I confirm that Acrobat Reader follows the textedit URIs and open the 
LilyPond app, but cannot refresh the document when the file is updated. 
I've read that this feature is only in the Pro version.


Ok, let's forget about proprietary software.
I've now installed Skim reader, which works great:

- it opens LilyPond app when you click on the notes
- it's opened by LilyPond app when you compile the music, if you set 
Skim as default PDF viewer

- you can set automatic refresh in the preferences

Now the last thing I'd like to change is the application to launch: I 
want to replace the (primitive) LilyPond app  with a more modern text 
editor.

Does anybody know how to do it?

I guess I'll write a small post on lilypondblog.org if I manage to get 
all working.


Thanks

You can use \applyContext for getting it before you initiate your own
(hopefully uniquely named) Staff.



Thank you for the suggestion, which looks like it's what I need. 
However, unfortunately I didn't get anywhere looking at the various 
examples in the docs. It's still a mystery to me what does what and 
evaluates to what and when that happens or not ...


OK, \applyContext passes the current context as the single argument to a 
function. Within that function one can access (retrieve and set) the 
properties of that context. I can sort of understand what that does in 
the example with "desaturating" colors.


But that function call always returns a (make-music 'ApplyContext ...) 
music expression, which is nothing I can use for my purposes, it seems 
everything is about the side-effects.


So I thought I'd define a variable and have the \applyContext function 
populate that variable with the context name, so I could use that later. 
But that doesn't work either, it looks like the \applyContext is only 
executed *after* I would need to use the variable:


\version "2.19.80"

ossia =
#(define-music-function
  (music ossia-music) (ly:music? ly:music?)
  (let ((name "initialized"))
#{
  \applyContext
  #(lambda (context)
 (set! name (ly:context-id (ly:context-parent context))) ; I know this 
has to be more robust ...
 (ly:message "1. context name inside \\applyContext: ~a" name)
 ; the following \new Staff has no effect
 #{ \new Staff { c' } #})
  #(ly:message "2. context name after \\applyContext was called: ~a" name)
  #music
  % Create \new Staff with ossia-music
#}))

\new Staff = "My Staff"
\relative {
  g'8 a b c
  \ossia { d c b a } { c b a g }
  g b d b g2
}

=>
Parsing...
2. context name after \applyContext was called: initialized
Interpreting music...
1. context name inside \applyContext: My Staff

I'm sorry, but I need more concrete pointers or even an example.

Re: Interactive PDF Link to Notes in Preview

[Zone Dremik]

Click-to-View was such a valuable feature. I could click on notes, chord 
symbols or lyrics, and the URI link would open the correct .ly file and 
highlight the exact text-code. (My oldest files date from 2009. I've been 
enjoying this feature a long time, and really miss it.)

This was with Mac OS 10.8.6 (Mountain Lion). I upgraded last month to OS 11 (El 
Capitan)

I would be interested to know how other users make corrections to the scores 
they have typeset. I am not enjoying the need to read through all the text to 
fix wrong notes and typos. (I have many!)

Switching to Skim or another PDF viewer is a logical suggestion. I would 
appreciate hearing from any users who who can verify whether the URIs properly. 
I suspect Apple is now suppressing any links and scripts embedded in PDFs for 
security reasons.

Sure.  And the side-effect you want is setting the alignAboveContext
context property.  Which is not trivial if the context does not even
exist yet.  Cough cough.  It would be possible to \once\set
alignAboveContext in the mother context and let it be inherited but if
the mother context does not yet have a vertical axis group of its own,
this is going to end up one ugly mess.

   This is being called during iteration.  It is only during
   iteration that contexts actually exist.

   The return value of applyContext, in this case a music
   expression, is not being used.

This is being called during input, even before LilyPond's parser
reads the following line (whatever may be in it and which ever
music expression or score it may end up being used or even not
used).

I'll do an example in the spirit of my hand-waving original proposal but
it's, well, not pretty.

\version "2.19.80"

ossia =
#(define-music-function
  (music ossia-music) (ly:music? ly:music?)
  (let ((name "initialized"))
#{
  \applyContext
  #(lambda (context)
 (set! name (ly:context-id (ly:context-find context 'Staff))) ; I know this has to be more robust ...
 (ly:message "1. context name inside \\applyContext: ~a" name))

  << \new Staff \with {
	#(ly:make-context-mod
	  `((apply ,(lambda (c)
		   (set! (ly:context-property c 'alignAboveContext) name)
		 (ly:message "2. context name after \\applyContext was called: ~a" name)
  } { #ossia-music }
  #music
  >>
  % Create \new Staff with ossia-music
#}))

\new Staff = "My Staff"
\relative {
  g'8 a b c
  \ossia { d c b a } { c b a g }
  g b d b g2
}

Kieren, I can't believe you use the text edito bundled in the LilyPond 
app! :-)

Which text editor are you using?
How did you set Skim to open the editor you want?

Hi David,

thank you for the explanations and the example.

On first sight it looks like I'll be able to get where I want with that. 
Although of course it'll be pretty complex (maybe "messy" would be more 
honest) once I try to transplant it from the MWE to the actual case ;-)


But I'll have to do that later ...

the mother context does not yet have a vertical axis group of its own,
this is going to end up one ugly mess.


So I thought I'd define a variable and have the \applyContext function
populate that variable with the context name, so I could use that
later. But that doesn't work either, it looks like the \applyContext
is only executed *after* I would need to use the variable:

\version "2.19.80"

ossia =
#(define-music-function
   (music ossia-music) (ly:music? ly:music?)
   (let ((name "initialized"))
 #{
   \applyContext
   #(lambda (context)
  (set! name (ly:context-id (ly:context-parent context))) ; I know this 
has to be more robust ...
  (ly:message "1. context name inside \\applyContext: ~a" name)

This is being called during iteration.  It is only during
iteration that contexts actually exist.


  ; the following \new Staff has no effect
  #{ \new Staff { c' } #})

The return value of applyContext, in this case a music
expression, is not being used.


   #(ly:message "2. context name after \\applyContext was called: ~a" name)

 This is being called during input, even before LilyPond's parser
 reads the following line (whatever may be in it and which ever
 music expression or score it may end up being used or even not
 used).


   #music
   % Create \new Staff with ossia-music
 #}))

\new Staff = "My Staff"
\relative {
   g'8 a b c
   \ossia { d c b a } { c b a g }
   g b d b g2
}

=>
Parsing...
2. context name after \applyContext was called: initialized
Interpreting music...
1. context name inside \applyContext: My Staff

I'm sorry, but I need more concrete pointers or even an example.

I'll do an example in the spirit of my hand-waving original proposal but
it's, well, not pretty.

I just manually launch the PDF in Skim once, and place it on my second screen 
(Frescobaldi takes up the first screen). After that, Skim automatically updates 
whenever Frescobaldi finishes compiling the PDF.

So you are not using point-and-click from Skim to Frescobaldi, right?

Ah! No… I use Skim for previewing, zooming in/out, pagination checks, etc. — 
it’s so much better than Frescobaldi’s previewer — and then use Frescobaldi’s 
previewer for point-and-click navigation. That combo works great for me, though 
I suppose I'd be even happier if either Skim linked back to the Frescobaldi 
code, or Frescobaldi’s PDF viewer were better.

Sorry for the noise!

Re: dotted semicircle indicating harmonics

[Orm Finnendahl]

Hi Pierre, Sylvius,

 I did some tests to get a better understanding of lilypond's handling
of markup. Below is an even more condensed version and also an
iterative solution in comparison for anybody interested in scheme
programming: Both functions should create the same result; the first
is somewhat more sexy not needing (re)assignment, but the second
version might be easier to understand for people not familiar with
functional expressions like "fold".

Sorry for the continued noise, but I thought I'd post it in case it is
helpful for somebody on the list.

Re: Interactive PDF Link to Notes in Preview

If you're looking to have this feature work, and are running linux, I was only 
able to do it by building an older version of xpdf (for the pdf viewer) and 
using GVim (not regular Vim) for the point and click feature.  It still works 
but it seems the feature hasn't been updated since most people use Frescobaldi. 
 I much prefer Vim

Huh?  Should work with anything you put in the EDITOR variable really.
Use it with emacsclient myself and a current version of Xpdf on Ubuntu.
I think it would also work with Evince et al (following instructions in
UG) but haven't tried recently.  Let me try:

Ok, refuses due to "permissions" in Evince, works in Atril.  Checking
the Evince setup according to UG...  It's set up like described.  But it
would appear like since I am not running GNOME actually (but xfce4) that
Evince is missing its infrastructure.  Like gnome-open or gvfs-open.

Evince works out of the box (without the need of any further

I've investigated a bit.
It does not depend on Skim:
https://sourceforge.net/p/skim-app/mailman/message/32211547/

This app:
http://www.rubicode.com/Software/RCDefaultApp/

allows to associate a command to textedit URLs.
I may assign lilypond-invoke-editor, but it doesn't work in Mac. A GUB 
issue¹, so I'm not optimist about a possible solution.


I wonder how the LilyPond app manages to pass the right command to open 
the URLS.
I've grepped textedit in the LilyPond.App dir and found something in 
the .plist file, but again it's too much for my first day as a 
temporary Mac user :-)



¹ Problems with lilypond-invoke-editor in Mac:

1. Wrong shebang:
$ head

#!/home/gub/NewGub/gub/target/tools/root/usr/bin/guile -s
!#

2. GUILE_LOAD_PATH must be manually set in ~/.profile

3. libguile error (I haven't solved this)
