Re: Increase distance from staff for dynamics

[B~M]

Simon is there a similar command which fixes the padding for text spanners,
or does the command you posted do that anyway ?

Page numbers in ‘number’ style

[Simon Albrecht]

Hello,

I just wanted to share this idea with you: Often, the visual distinction 
between page and bar numbers, which may be very close to each other, 
poses a problem. By chance, I noticed in a reproduced volume from the 
1920’s Brahms edition that it uses a typical ‘number’ font like in time 
signatures  for the page numbers. Which is nice, because a) I like 
this kind of font, b) they’re very visually prominent and legible at 
small sizes and c) they are clearly different from bar numbers that way.


So my standard style sheet now features these lines (adjusted from 
ly/titling-init.ly):



\paper {
  oddHeaderMarkup = \markup
  \fill-line {
""
\on-the-fly #not-part-first-page \fromproperty #'header:instrument
\on-the-fly #print-page-number-check-first \number \fromproperty 
#'page:page-number-string

  }

  %% evenHeaderMarkup would inherit the value of
  %% oddHeaderMarkup if it were not defined here
  evenHeaderMarkup = \markup
  \fill-line {
\on-the-fly #print-page-number-check-first \number \fromproperty 
#'page:page-number-string

\on-the-fly #not-part-first-page \fromproperty #'header:instrument
""
  }
}
%

Best, Simon

This would only work if the dynamics were in a Dynamics context of their

Re: Using .info documentation in emacs

[Kevin Barry]

OK so I downloaded the tarball from the lilypond website and added the
info directory to the Info-default-directory-list, but that didn't
work, even after adding all of Hwaen's suggested entries to the dir
file (is there a reason this is empty?).

I can manually open the dir file with Info and I can follow menu
entries, but images don't appear and the normal info navigation
doesn't work properly. I don't know what I'm doing wrong.

Re: Version 2.18 vs.2.19 speed and W10

[tisimst]

Just thought I'd add my two cents. I'm using Windows 8 and I only see a small
speed increase between older versions and 2.19.47.

Using:

\repeat unfold 200 { \tuplet 5/4 { c'4 d' e' f' g' } }

and compiling in "publish" mode (i.e., no point-and-click links) I get the
following results:

2.18.2 - 6.5 seconds
2.19.36 - 2.7 seconds
2.19.47 - 3.0 seconds

FWIW,
Abraham

If I point info to the dir file with C-u then it will load the
lilypond entries (although the images didn't appear). I will try
downloading the info docs off the web and using those and see if that
works.

Good catch, I overlooked this.

Well, at first it's a matter of code-hygiene. Those variables were
filled by the engraver doing it's work, why not clear them?
Additional I fear bleeding over, if the same engraver is used while
compiling multiple scores/files. Or if he is put into multiple
contexts of the same score.
Not entirely sure about this, but better be a paranoiac ;)


Thanks for your thorough review.
I think I'll follow your suggestion and put it in the LSR.

Tags and chord repetition

[Peter Crighton]

Hello all,

I came upon some unexpected behaviour when using a tag on, for example, a
markup that is attached to a chord repetition symbol (see below).
How can I fix this, so only the markup and not also the chord repetition
symbol gets tagged?


\version "2.19.47"

x = \tag #'tabstaff ^x

music = \relative c {
  c4 c c c\x
 \x
  q q q q\x
}

\new StaffGroup <<
  \new Staff \keepWithTag #'staff <<
\clef "treble_8"
\music
  >>
  \new TabStaff \keepWithTag #'tabstaff <<
\tabFullNotation
\music
  >>

Peter

The problem with this is (as Harm pointed out already rather at the
beginning of this thread) that there may be elements at the wrong size
at the changing spot. See

  SNIPPET BEGINS
\version "2.19"

\header {
  tagline = ##f
}

\layout {
  indent = 0
  \context {
\Score
\remove "Bar_number_engraver"
\omit TimeSignature
  }
}

{
  c'4 d' e' f' g' a' b' c''
  \magnifyStaff #(magstep 3)
  \break
  \key a \major
  \repeat unfold 13 { s1 }
}
  SNIPPET ENDS

When you want the second system to be empty (for someone to fill in) you
won't have the key signature, but the barline is also at the wrong size.

Hi Harm,  Nice work!  I'd say this is a good candidate for the LSR, 
particularly because it demonstrates listeners, acknowledgers, and 
finalize in one engraver.


One little thing I noticed is that

  (if duration-marks

should be something like

  (if (not (null? duration-marks))

Because:

  \version "2.19.42"
  #(define empty-list '())
  #(display (if empty-list #t #f))
  % --> #t
  #(display (if (not (null? empty-list)) #t #f))
  % --> #f

Also, I wonder, where you clear out these variables at the end of the 
finalize stage:


 (set! evts '())
 (set! last-evt #f)
 (set! tempo-change-evts '())
 (set! duration-marks '())

Of course, it doesn't hurt, but is it necessary?  If so I need to do 
that in my code.

I’m not sure “bizarre” was a necessary descriptor… On a mailing list (such as 
this one) where people are generously donating their time to help people who 
post, those kinds of words can often be counterproductive.

The following version does not require the creation of a new score.

Did you restart Emacs?  There are also key sequences for rereading the

If that doesn't help, obviously the provided lilypond-doc package is
