According to NR 4.1.4 
,
 the reference point of top-level markups is indeed their highest point, not 
the baseline (as opposed to, e.g., Lyrics lines).

Yes, unfortunately. If you want consistent spacing (assuming that you don't put 
anything fancy in your titles, such as graphics or multi-line stuff, and that 
you use a font with sane glyph heights), you should be fine with an additional 
\strut in the title (see 
).

  title = \markup \concat { \strut "Title" }
  title = \markup \concat { \strut "e" }

You could also adjust bookTitleMarkup or scoreTitleMarkup (see NR 3.2.2 

 and /usr/share/lilypond/*/ly/titling-init.ly or the equivalent on your system 
for the default) to take that into account; e.g., change the line

  \fromproperty #'header:title
to
  \concat { \strut \fromproperty #'header:title }

in the definition of bookTitleMarkup.

thanks for your information. Unfortunately, it didn't fix the problem.
The installation program offered to deinstall or repair-install the

I've tried to repair it (no luck), afterwards to deinstall and 
re-install it, and finally even deinstalled the x64 version that was on 
my system as well.

The problem with frescobaldi persists.

Is there a way to check if all components of the Redistribution pack are 
correctly available to the system?

Re: Differing header position depending on tallest letter

2017-03-10 Thread Peter Crighton 
Hmm, that doesn’t seem to work.
I didn’t know about \strut before, and I’m not sure if I
correctly understand how it works, but doesn’t the size of the box depend
on the whitespace character and not on the tallest character? I don’t know
which height, if any, a whitespace character in a font normally has, but at
least with LilyPond’s standard text font and with Gentium Book Basic, which
is the one I’m currently using, it doesn’t work.

Push note column to the right when it has a broken tie/slur attached

2017-03-10 Thread Urs Liska 
Hi all,

Is it possible to push the first note column of a system to the right
when it ends a tie or slur?

I'm working on a custom stencil for ties and slurs and in this situation
it needs much space between the Time/key/clef and the first note. I
assume that when overriding the stencil I can't move the note column
anymore, is that correct?

So is there another option to determine that a note column is

* the first in a line and
* ends a broken tie/slur

and still being able to move it?

TIA
Urs

I once solved a lyrics spacing problem using a strut of my own making.
Something like:

Yes, this would indeed work, but the approach is quite ugly:

\header {
  title = \markup \overlay {
\transparent \fontsize #1 "|"
"Title"
  }
}

Also, the PDF file’s title would be “| Title”, which is annoying (but could
probably be avoided by adjusting \bookTitleMarkup).

I don’t suppose there is a way to change a markup’s reference point to
being the baseline?

Hi Peter,

You should really handle the presentation manipulation in the presentation 
layer, not the content layer:

\version "2.19.54"

\paper {
  scoreTitleMarkup = \markup {
\combine \fromproperty #'header:title \transparent "Tj"
  }
}

\header {
  title = "Title"
}

{ c'4 }

Hope this helps!

A markup's reference point _is_ the baseline.  It's more a question of
what to do with _stacks_ of markups because a single reference point
cannot simultaneously represent the height of the top line and the depth
of the bottom line.

Hi David,

Really??

> It's more a question of what to do with _stacks_ of markups

These aren’t stacked:

\version "2.19.54"

{
\override Score.RehearsalMark.extra-spacing-width = #'(-0.5 . 1)
\override Score.RehearsalMark.self-alignment-X = #LEFT
\mark "ALL CAPS"
c''1
\mark "jumping"
c''1
\mark "the big dig"
c''1
}

So why aren’t they baseline aligned?

Thanks,

Because there isn't enough room for that?

Try

  \override Score.RehearsalMark.Y-offset = 4

and you'll see the baselines aligning.

LilyPond does not actually track colors in any manner if I remember
correctly.  It just passes them through.  So take a look at how RGB
support is done, and CMYK support should be straightforward to add.
Instead of adding new user-level commands, you could just permit the
color commands to accept lists with 4 members as well as three and then
just let the backends emit different commands.

That's minimally invasive but would not allow us to use RGBA in a
similar manner.  But maybe partial transparency is better dealt with
using separate primitives anyway.

Re: CMYK colours

2017-03-10 Thread Andrew Bernard 
Hi Urs,

Not directly the answer to your question, but. Adobe Acrobat DC allows one
to convert the colour model in a PDF to  large set of choices, including
CMYK. Therefore it is possible to post process lilypond colour output to
CMYK. Granted, not an open source solution, but the pre-press technology is
certainly readily available.

Do you really want CMYK colours or is it that you want spot colours in your
output?

Most professional print shops will do RGB to CMYK conversion nowadays as
required for their particular print devices. What is the reason for wanting
to specify CMYK rather than RGB in the lilypond source?

Andrew

Control of spacing between left edge and first note

2017-03-10 Thread Thomas Liggett 
Hi all,

I have a staff without any initial clef, time signature or key signature, and 
want to increase the space between the left edge of the stave and the first 
note. The method below works for the first system, but then reverts to the 
default (closer) spacing for the second system.

I’ve referred to the manuals and this snippet: 
http://lsr.di.unimi.it/LSR/Item?id=648

(I could only seem to control the spacing by retaining the clef (although made 
invisible as a point-stencil) between the left edge and the first note, 
although it would seem preferable to omit it if possible.)

Thanks,
Thomas

left edge and clef

Hi Thomas,

Try this perhaps.

[You have to retain clefs and barlines and render them transparent, so that
they exist to reference off. One ought to be able to just set the value
(key-signature extra-space . 8) say, but I am not sure why we need the
whole shebang alist.]
