Re: Unknown marking in Roman print (1710)

Can you give a bit more context? What instrument? Can we see the signs at the 
bottom of the image? Who is the composer? The work? More clues would help.

On my phone, it looks like a blobby lower-case t, which makes sense in
context.

I'll do so ASAP. I'll have to sort out things as there were a number of
interesting things happening there, though.

Yes, it is written in C++, without dependencies and has been compiled to
a number of platforms. The one most commonly in use is JavaScript
(compiled to that through Emscripten).

I have seen a presentation/tutorial workshop this week, and I must
really say that is an incredible piece of software. It is able to do
near-instantaneous engraving *in* the browser, with rescaling,
reselecting and everything, at an enormous speed.

It has a completely different target than LilyPond, though, and will
probably never reach anything near publishing quality engraving.
Therefore the current trend in digital music edition is to pursue a
two-way path for user interfaces: use Verovio for everything in content
editing and (flexible) end-user visualization, and (hope for being able
to) use LilyPond for print-quality engraving of selected readings.

One extremely interesting kind of approach that is made possible through
Verovio is having score documents (in MEI format) retrieved through a
URI and render them in-place. There are also tools/specs available to
address specific parts of a score through a URL and have only that
engraved. Another thing I saw is that the displaying website can
retrieve exceprts from that remote document using XSLT or XPath queries
and have that rendered instantaneously.

I think for any application where
- SVG is a suitable option
- isntant re-engraving is an issue (mobile platforms for example)
- publication quality isn't the target
Verovio is definitely something to look into.

Switching the direction of slurs in tupletBracketToSlur

2016-05-21 Thread Richard Shann 
A while ago I asked about using slur-shaped tuplet brackets and someone
kindly posted the tupletBracketToSlur definition (pasted below).
This works nicely except that the slur is always on the same side as the
beams and stems, whereas it is usually placed on the opposite side.
I've been setting by hand but I wondered if I could set 

\override TupletBracket #'direction = #???

to some value that would result in the opposite choice to its "auto" one
in each case.

Richard

tupletBracketToSlur = {
  % Use slur-stencil
  \override TupletBracket.stencil = #ly:slur::print
  %% Use 'thickness from Slur
  \override TupletBracket.thickness = #1.2
  %% 'control-points need to be set
  \override TupletBracket.control-points =
#(lambda (grob)
  (let* ((x-pos (ly:grob-property grob 'X-positions))
 (pos (ly:grob-property grob 'positions))
 (x-ln (interval-length x-pos))
 (dir (ly:grob-property grob 'direction))
 ;; read out the height of the TupletBracket, maybe negative!
 (height (- (cdr pos) (car pos)))
 ;; height-corr is introduced because sometimes the shape of the
 ;; slur needs to be adjusted.
 ;; It is used in the 2nd/3rd control-point.
 ;; The value of 0.3 is found by trial and error
 (height-corr (* 0.3 dir height))
 (edge-height (ly:grob-property grob 'edge-height '(0.7 . 0.7)))
 (pad 1.0))
(list
  ;; first cp
  (cons
(+ (car x-pos) 0.5)
(- (+ (* dir pad) (+ (car pos) (* -1 dir (car edge-height
  (if (= dir -1)
  (if (> height 3)
(/ dir 2.0)
0.0)
  (if (< height -3)
(/ dir 2.0)
0.0
  ;; second cp
  (cons

  ;; third cp

  ;; fourth cp

  \override TupletBracket.staff-padding = #'()

As others have said it's rather unlikely that LilyPond might ever work
on iOS. And maybe it will not be the ideal tool for your use case either.

I suggest you have a look at the Verovio library (http://verovio.org),
which is a tool intended for high-speed flexible in-browser (for example
JavaScript) rendering of music.

Re: Embedding LilyPond in iOS app?

2016-05-21 Thread Robert Schmaus 

Hi John,

I'm not an iOS programmer, but fwiw, I remember a discussion about this 
topic from some years back.


One thing that came up is that, in iOS, it's not possible (i.e., 
allowed) to build a iOS lilypond app which is then called from some 
separate text-editor app. Thus if anything, one would have to build an 
editor and have lilypond running in that same app.
And as for inserting Lily output (png) into yet another app, I guess 
that would be forbidden as well, unless you think about pushing the 
output to - say - a Dropbox folder. Thus that app would need to contain 
all viewing capabilities itself, too. And of course there's the thing 
with file storage - Dropbox again?


Let me put it this way, there already was serious interest in having 
Lilypond in iOS, and I'm pretty sure we would have some sort of example 
of that already, if it were a realistic thing to do. That's no proof, of 
course ...


Again, I'm no expert on this, just what I remember.
Best,
Robert
