parser location inTab

[Gack McShite]

Trying to clean up errors.  I see this pattern a lot, so I assume it
should work.

TrackAVoiceAMusic = #(define-music-function (parser location inTab) (boolean?)
#{
   \tempo 4=106
   \clef #(if $inTab "tab" "treble_8")

and then later

   \context Voice = "TrackAVoiceAMusic" {
  \TrackAVoiceAMusic ##f
   }


or

   \context TabVoice = "TrackAVoiceAMusic" {
  \removeWithTag #'chords
  \removeWithTag #'texts
  \TrackAVoiceAMusic ##t
   }

Originally had \version "2.14.0"
changed to \version "2.18.0"
Same result.

Thanks for hints.

Oh, thank you! Did you also build the LilyPond PDF manuals in that
Google Drive share? I notice they are 2.19.82 without the defects in
the notation images currently found on the website copies. I'm glad to
see all the GUB work happening, hopefully there can soon be a clean
build of LilyPond that gets proper PDFs put up again.

In case it helps your friend, I've attached a PDF of the Guile 1.8.7
docs which can be used as a more technical reference for the specific
flavor of Scheme used by LilyPond.

The other day I was putting together a set of PDFs for my own offline
reference and found that the GNU website only includes a PDF download
for the latest version.  As there are some differences from the
version LilyPond employs, I had to download the source and manually
run the docs through texi2pdf.

Re: Text spanner shorten-pair

[Carl Sorensen]

From: Andrew Bernard 
Date: Friday, January 25, 2019 at 6:21 AM
To: lilypond-user Mailinglist 
Subject: Re: Text spanner shorten-pair

Hi Aaron,

I know. This then implies the NR is in error. Do we report a bug? [For the 
reason that being thrown off the scent I spent hours looking all in the 
interfaces to no avail.]

I think this is absolutely a bug.  It should not say shorten-pair applies to 
TextSpanners when it does not.

There are three possible solutions I can see:


  1.  Fix the description of shorten-pair to indicate which spanners it applies 
to
  2.  Create a new interface e.g. shortenable-spanner-interface that contains 
shorten-pair, and then give that interface to all the grobs that accept 
shorten-pair (see dynamic-line-spanner-interface for a similar single-property 
interface).

The padding works. Seems inconsistent to me. Why do we leave TextSpanners out 
of the group?

  1.  Add the shorten-pair property to the spanner-interface (or maybe the 
text-spanner interface) and make sure it works with all of the objects having 
that interface.

My preference right now would probably be #2.

I have not made an exhaustive study of this, but my initial thought is that 
there are two kinds of spanners.

Spanner type A goes from one grob to another (e.g. TextSpanner, glissando).  
These spanners can be shortened by adding padding, because they will need to 
move away from the grobs that they connect when the padding is increased.

Spanner type B goes from one column to another (e.g. hairpin, pedal bracket).  
These spanners don’t have grobs at their ends, so padding will not be effective 
at shortening them.  Hence the need for another method, as met by the 
shorten-pair property.

One could add the shorten-pair property to the type A spanners, but it’s not 
necessary to do so to shorten them.

I don’t know what I prefer for the long-term solution.  It would take more 
study and consideration of the pros and cons of each method.

Thanks,

Carl

Re: harp basic muffle

[Rachel Knight]

Hi all,

In super old scores, an asterisk was used, but that is not true of scores 
today. The example below that says English Ballad is from 1942. The next one is 
from 2005 and seems to be what is standard. The final one is one I created last 
year with Finale so you could see what proportions they chose. (It is extra 
large as the book is for younger students.)

After studying these examples more, I adjusted the settings to make it 
consistent with current examples.

mufflePath= \markup \path #'0.15 #'((moveto -1.125 0)
(lineto 1.125 0)
(moveto 0 -1.125)
(lineto 0 1.125))

muffleMarkup= \markup \translate #'(1.2 . -1.5) 
 \combine \mufflePath \draw-circle #.75 #0.15 ##f

It would be wonderful for harpists if this glyph could be added.

Best,
Rachel

At least here
\usepackage[debug=true, nofragment, noragged-right, 
program=C:/LilyPond/usr/bin/lilypond.exe, 
includepaths=C:/Users/mgd/Documents/lilypond-Noten/include]{lyluatex}
works while
\usepackage[debug=true, nofragment, noragged-right, program={C:/Program Files 
(x86)/LilyPond/usr/bin/lilypond.exe}, 
includepaths=C:/Users/mgd/Documents/lilypond-Noten/include]
{lyluatex}
doesn't. However the errormsg seems to indicate that when enclosed in {} the 
problem is that when invoking LP the path would either need to be enclosed in 
'' or the spaces should be escaped.

Kind regards,
Michael

It's not listed under any of the interfaces that TextSpanner supports.  
Instead, it looks like Hairpin, HorizontalBracket, OttavaBracket, 
PianoPedalBracket, TupletBracket, and VoltaBracket are the only things

That all said, it looks like bound-details.left/right support padding:

Text spanner shorten-pair

[Andrew Bernard]

Do TextSpanners support shorten-pair?

The NR for 2.19.82 says:

shorten-pair (pair of numbers)
The lengths to shorten on both sides a hairpin or text-spanner such as a
pedal bracket. Positive values shorten the hairpin or text-spanner, while
negative values lengthen it.

This does not work:

\version "2.19.82"

{
  \override TextSpanner.shorten-pair = #'(-3 . 2)
  c''4\startTextSpan
  c''4
  c''
  c''\stopTextSpan
}

What's happening? Did this work in the past?

Unfortunately not.


I know it's incomplete, but I still consider it the best resource for

That's basically correct.




That does look like it needs changes to project settings, though. I 
tried cloning or downloading the GitLab repository so I could do that 
myself, but the private GitLab instance appears to not allow that. The 
downloads save as empty files and git clone gave an HTTP error of some 
sort.


This is a configuration problem of the Gitlab instance on that 
particular server, for some reason (unknown to me) both downloading and 
cloning is only possible through SSH with a registered SSH key. I was 
basically interrupted in the middle of moving all my stuff to a new 
server and didn't really recover from that shakeup.


What I *can* do is move this repository to my new server where it should 
be possible to get the code - but ...




Comments? If this project wasn't intended for availability as a PDF, 
I'll just omit it from the collection I'm gathering.


... I would be happy to provide this resource as a PDF too, and yet, 
Gitbook allows to do that.


However, the "other" thing I got stuck with at some point is that I 
couldn't get Gitbook working anymore. The basic Gitbook process would 
still work, but I didn't manage to get my custom plugin to work that 
uses python-ly to produce the syntax highlighting. That shouldn't be 
rocket science, but I didn't have the time to familiarize myself more 
with the matter.
(In addition this means that a number of fixes that I applied after 
people pointed me to them aren't available in the online version of the 
book).


In fact I would consider switching from Gitbook to another build system, 
for example based on Pandoc, maybe readthedocs.org would also be an 
alternative. The content is encoded as a bunch of Markdown files, with 
one "TOC" file organizing them to a hierarchy. The specific syntax for 
including stuff like code examples should easily be convertible with 
'sed' or similar tools, so that should in fact be a viable solution - 
provided there's someone who'd be willing to help me with the transition.
