you won't like this:
It is not meant to be compiled natively.

If you want to do that anyway you'd have to do the porting all for
yourself.

Note I'm not saying it can't be done.

Kind regards,

How to build LilyPond.app on macOS?

[Mojca Miklavec]

Hi,

Can someone please provide me a hint about how to build LilyPond.app
on macOS (natively, without any cross-compiling, ideally without
compiling any dependencies like ghostscript etc.)?

I checked lilypond-2.19.51.tar.gz, but it's not clear to me where the
sources for that would be. There is no obvious configure option and I
didn't find the relevant/needed files like Info.plist.

I found
http://lilypond.org/doc/v2.18/Documentation/contributor-big-page
(didn't read it all) and only suspect that some logic might live in
GUB, but I'm pretty much lost for the moment.

I would like to see LilyPond.app being distributed in a package
manager, but for that to happen I first need to understand how to
build it.

Bonus question (I'll probably ask separately). PDF viewer shows hyperlinks to
textedit://path/to/file.ly
How does the OS know that it has to open LilyPond.app for that as is
there a way to configure that, so that the file gets opened in another
editor? I configured the system to open my favourite text editor on
double-clicking, but it has no effect when I click on a hyperlink.

Thank you,
Mojca

(please CC me)

Thanks for this. Seems to work perfectly.
I renamed your parenthesize function because it would break the regular
\parenthesize command.

\cadenzaNotes takes three arguments. The first is a boolean, set it
false to get rid of the fermata over the MultiMeasureRest.

Thanks for finding this! Ideally it would be nice to not have the fermatas
over the rests, but if that's tricky to do, then this version is fine.

Yep.
\headers can be set at very different levels, I simply don't know how

Falling back to markup-commands may work. See below.
Though, I fear you'll have no difficulties to get it broken. Regard it

#(define-markup-command (my-with-url layout props url arg)

 ;; be aware: not recursing!!!
 (url-string
   (if (string? possible-url-string)
   (if (null? proc)
   possible-url-string
   (proc possible-url-string))
   ""))
 (url-expr
   (list 'url-link url-string `(quote ,xextent) `(quote ,yextent
(ly:stencil-add (ly:make-stencil url-expr xextent yextent) stil)))

#(define test-proc
  (lambda (strg)

strg)))

\header {

This is invalid syntax, you probably meant:
\new Staff \with { \consists Mark_engraver }

'\new \Score' is invalid syntax as well, but

\new Score \with { \remove "Mark_engraver" }
<<
\new Staff
  \relative c'' { c4 \mark \default s c2 }
\new Staff \with { \consists "Mark_engraver" }
  \relative c'' { c4 s \mark \default c2 }
>>

works fine. Though, it could easily be written like:

\score {
  <<
  \new Staff
\relative c'' { c4 \mark \default s c2 }
  \new Staff \with { \consists "Mark_engraver" }
\relative c'' { c4 s \mark \default c2 }
  >>
  \layout {
\context {
  \Score
  \remove "Mark_engraver"
}
  }
}

I vagely remember discussions about the topic years ago. Everyone
agreed, so the possibility to write
\new Score \with ...
is not mentioned anywhere at all, but still valid syntax.

Nope, not for the engravers being in the context or not.
You have to go for properties of context/grob/whatever read/written by
the relevant engravers.

Well, "spacer rests" don't create a NoteColumn, as opposed to Rests
(visible or not) and no grob is assigned to them.
No bug but a feature.

This becomes important once we want to deal with fancy glissandi.
(There may be other use cases apart from glissandi. It's just the one
I use sometimes.)

In the following example only the first measure puts out a glissando at all:

{
  c''4\glissando s c'''2
  \omit Rest
  c''4\glissando r c'''2
  \override Rest.after-line-breaking = #ly:grob-suicide!
  c''4\glissando r c'''2
  \override Rest.before-line-breaking = #ly:grob-suicide!
  c''4\glissando r c'''2
}

Currently I've no idea how we could keep that behavior _and_ giving
spacers some extend of there own, without creating a grob for them.

For the name, "spacer" may be ill-named, internally they are called
SkipEvents, which comes closer. Maybe "timer" would even more
appropiate, but sounds even more strange.

  Harm

It completely avoids \cadenzaOn/Off, because of the hassle you experienced.

Well, since writing the last email I found several posts on the Mint
forums where it is clearly stated that doing this is more or less
*guaranteed* to break the installation.

And I also found a longer article which made me realize one thing: when
I initially installed LMDE it was exactly because it was based on Debian
testing, as a rolling release. Obviously they incrementally stepped back
until they reached the point of basing on Debian stable, which
definitely isn't what I intended.

Exactly. Recreating the tools I use, partially compiled from source,
partially from downloaded packages, partially from the distro's repos.

Additionally, I'm not so sure how I should proceed:
I have one "smaller" partition with ~30 GB, mounted as "/" and used for
the LMDE system. Unfortunately this is marked as the boot partition.
Then there's another partition of about the same size where I have
currently installed Ubuntu Mate (to test Frescobaldi 3), but I'd happily
replace that again with Debian.

Questions:
a) how to proceed with the boot flag? Can I simply mark the "new"
partition as bootable when installing Debian, will I then still be able
to boot into LMDE (which I'd want until I know everything works)?
b) how would I proceed with the (big) /home partition? What I don't like
about dual LInux-Linux boots is sharing a home partition. Well, this is
cool, but I find the configuration files disturbing and potentially
confusing.

In this code, the spacer rest takes up space in the proportional spacing

Hi Brin,

You are correct, however I just thought perhaps you could find it useful if
you knew at least I was not seeing any errors like you were - perhaps you
can try your score in a 2.19 version just as a test? Not sure what's changed
but, no errors here. :) Let us know what happens.

Yes, I agree that a transparent rest would be better called a spacer 
rest,

as it creates space for the rest.

However, with strict proportional spacing, I am surprised that an
invisible rest (s4) doesn't take up space.  I haven't looked at the code
to see why, but I would expect it to, as the music elements should be
printed exactly according to their start moment in proportional spacing.


Good - a relief to hear the surprise isn't all mine!
So I must now send you this score's setup commands,
which do include some custom stuff c/o You Guys.
Later today


And please on-list.

Hello,

Not sure this 100% answers your question, but for what it's worth, I just
copied and pasted your code into my Frescobaldi and the log showed no errors
and it engraved "correctly" as is. No "programming error" at all.

I used LilyPond 2.19.52.

Though, on a technical note, I'm unsure of the best way to handle the
pattern of repeatedly modifying a variable's value which the C++
source does in stencil functions.  I've tried to avoid use of set! --
instead declaring new variables in the course of a let* block.  But
maybe set! isn't so un-schemic and is better for eliminating levels of
nesting?

Good causes can be made for both. Using attachments prevents mangling of 
the code underway due to e.g. encoding issues or reformatting, and you 
can just open the file in Frescobaldi instead of having to copy & paste.


In fact, Thunderbird displays text attachments (and images) without 
having to open them externally, normal attachments as well as the kind 
of ‘inline attachment’ that is apparently supported by the e-mail

Here's another option for you that I created recently that creates brackets
roughly the same size as the real parentheses glyphs, so I think it (the
second one I describe in that message) tends to look a little better than
relying on the stencil of the accidental because, for example, you'll get

Yes, you can find more on the debian wiki.

The transition was smooth.

No rollback, as far as I know.

I guess more than a risk, but you'd better ask on Mint support channels.





 My suggestion is switching to Debian testing.
 Why did you choose Linux Mint? Because of desktop environments
 alternative to Gnome which were not available in Debian?


Actually I don't really recall what was the trigger for me to switch.
Maybe I had some issue with the Debian/Gnome setup I had, or I just
wanted to try out something different after reading about Mint?
Anyway I chose LMDE, which is a Mint based on Debian instead of Ubuntu

I liked the Cinnamon desktop, and maybe that wasn't (isn't) available

If I don't have to fear transition quirks I'd also be open to try out
others, though.


Cinnamon is available in stable and testing as well:
https://packages.debian.org/search?keywords=cinnamon

I would install debian testing from scratch.
What is keeping you from doing so? Migrating your configurations is 
boring?

Yes, this works fine here since two divs are needed.  There doesn't seem 
to be a way to produce a single div with both an id and classes (as is 
routine in HTML).  Ideally we'd have a single macro for divs that let 
you assign an id (or not) and classes (or not) to the div. That would be 
more intuitive for those used to HTML.



The macros could be easily extended to add multiple classes (if they
don't do that already; I can't recall).


The uses of divClass in the itexi files appear to have just a single 
class, but I took a look at the divClass macro in common-macros.itexi 
and tested it and it already works for multiple classes:


@divClass {first-class second-class}

And looking at the other macros I see how to write a macro that creates 
a div with ID and classes:


@div {an-id,first-class second-class}

I'll post a proposal on the dev list and/or prepare a patch.

Cheers,
-Paul

mmrest-of-length and \cadenzaOn

[Brin Solomon]

Hello all,

I'm trying to typeset a piece where one player has an unmetered cadenza
while every other player rests. I'm trying to use mmrest-of-length to
generate the rests, but if I use \cadenzaOn, I get the error "programming
error: Multi_measure_rest::get_rods (): I am not spanned!" and the rests
are not printed. This error doesn't happen if I use skip-of-rest instead,
but in that case, I don't get the rests.

Here is a minimal example that demonstrates the problem:

%%

\version "2.18.2"

MyCadenza = \relative c' {
  c4 d8 e f g g4
  f2 g4 g \bar "|"
}

\new GrandStaff <<
  \new Staff {
\cadenzaOn
\MyCadenza
\cadenzaOff c'1
  }
  \new Staff {
\cadenzaOn
#(mmrest-of-length MyCadenza)
\cadenzaOff
c'1
  }
>>

%%%

I'm running version 2.18.2 on Mac OS 10.11.6. Is there a different command
I should be using to get a full measure rest while I'm using \cadenzaOn?

Thanks in advance,
Brin

Mmmmh, I see.

Actually I don't like any of these ...



I've used Debian testing for several years (switched to Fedora last 
year) and I can tell that it's stable.
I can't remember any big problem or instability issues. If you happen 
to be hit by a bug in some package, it will be fixed quickly, because 
it's a rolling release, often updated (this may be seen as a drawback, 
because upgrades and downloads of packages are more frequent than in 
stable releases).
Debian stable has a very slow release cycle. I've never been able to 
use it because of this.


My suggestion is switching to Debian testing.
Why did you choose Linux Mint? Because of desktop environments 
alternative to Gnome which were not available in Debian? Both Mate and 
LxQt are available in testing/stretch:

https://packages.debian.org/testing/lxqt

Changing context plugins

[David Sumbler]

This question arises out of a problem I had in the piece I am currently
setting.  I have certain marks I wish to appear above a bar-line.  I
want one of them to appear only in the lower stave.  In this particular
instance I can get the result I want thus:

%%
\version "2.19.48"

\language "english"

firstmark  = \mark \markup { \whiteout "First" }
secondmark = \mark \markup { \whiteout "Second" }

\score {
  \new StaffGroup {
<<\new Staff { R1 \firstmark R R }
  \new Staff { R1 R \secondmark  R }
>> }
  \layout {
\context { \Score
   \remove Mark_engraver }
\context { \Staff
   \consists Mark_engraver }
  }
}
%%

But two questions have occurred to me arising out of this.

1) Plug-ins for most contexts can be added or removed either in a
\layout block, as above, or when creating the context, e.g.

\new \Staff \with { consists Mark_engraver }

But this second method can't, so far as I can see, be used with a Score
context, because '\new \Score' is not allowed.  Can Score plug-ins only
be added or removed within a \layout block?

2) More importantly, is it possible to change these settings at an
arbitrary point in the music, i.e. after the context has been created?
 I can't find any way to do that, although with my limited
understanding of the internal workings of Lilypond, there doesn't seem
to be any reason why it should not be possible.  (This is what I
started off attempting to do in my piece, without success.  I then
realized that in this particular case I could work around the problem,
as shown above, but in another case one might need to change things
part of the way through a piece.)

Re: Accidental in brackets

[Mike Solomon]

Hey!

Total hack, but if you check out scm/stencil.scm, you’ll see how parentheses 
are made…

(define-public (parenthesize-stencil
                stencil half-thickness width angularity padding)
  "Add parentheses around @var{stencil}, returning a new stencil."
  (let* ((y-extent (ly:stencil-extent stencil Y))
         (lp (make-parenthesis-stencil
              y-extent half-thickness (- width) angularity))
         (rp (make-parenthesis-stencil
              y-extent half-thickness width angularity)))
    (set! stencil (ly:stencil-combine-at-edge stencil X LEFT lp padding))
    (set! stencil (ly:stencil-combine-at-edge stencil X RIGHT rp padding))
    stencil))

So it looks like you can substitute in make-connected-path-stencil for 
make-parenthesis-stencil, using sensible parameters for the connected path 
based on the y extent and the width.

Re: Creating marginal comments?

[Knut Petersen]

Hi Tapani!

Two problems:
1. I'm producing a hymnal with 100s of entries. To keep things tidy, those
hymns are in separate .ly files, and I then use lilypond-book to compile
them into one document. To embed every music file in a single (massive) .tex
document is not realistic at this stage of the project.


Well, I agree that it is a good idea to keep the hymns in separate files. TeX knows 
"\input".
But I do not know how much work would it be to edit your scores. It might be an 
easy
automatic process using sed, it might be complicated ...


2. I'm too much of a newbie to understand /how/ your method works. Would you
be able to explain it to me in simple/ish terms, or do I just have to go
away and buy a LaTeX manual and really learn the language properly? OR,
alternatively, can I just insert the \newcount commands into my preamble and
use the \def\callback[etc.] argument in the document?

I prepared a somewhat commented version of hymex.tex. Having a LaTex manual
as well as the TeXbook is always a good idea.

Sorry, I didn't really know how to do a helpful example as I couldn't find
anything close to what I was after.

\shortVocalName gives me the vocal name at the start of each line, which is
not quite what I was after - I wanted to show exactly where (mid-bar) it
changes from one to the other.  Marc's suggestion does what I'm after.

I must say I'm a little bit worried because it's not just PyQt but

But

I must admit I don't really see through that.


 Don't know how Linux Mint works...


I *think* that with regard to packaging it should behave basically 
like

Debian itself. For example, unlike Ubuntu you can't add PPAs.


I found some wiki pages where it was recommended even the opposite, 
that is adding mint repositories to a debian system. So they should 
work fine together.
You may give it a try. aptitude will tell you what it's going to do 
before proceeding and you'll be able to say no if you see too many 
conflicts with other packages.


Your system is based on debian 8.4, that is Jessie, current stable.
So try appending this line to /etc/apt/sources.list:

deb http://httpredir.debian.org/debian testing main contrib

Then enable this repo only for the packages you want to take from there.
Create the file /etc/apt/preferences and try with these lines:

Package: python3-pyqt5
Pin: release a=testing
Pin-Priority: 900

Package: *
Pin: release a=testing
Pin-Priority: 1

Then update the repositories list and check if the pinning is correct:

aptitude update
apt-cache policy
apt-cache policy python3-pyqt5

I think that `aptitude upgrade` should automatically update the package.
If it doesn't, you can force the upgrade.

Now the problem is how many dependencies you need to upgrade and the 
conflicts that will occur.

Non-lyric text in lyrics

[Tom Cook]

I've googled for this, and looked through the lilypond snippets repository,
and can't find anything.

I'm trying to insert instructions mixed up with lyrics.  Actually its just
the name of the singer, but the name changes half-way through and changing
vocalName doesn't seem to do the right thing.

In case that's not very clear, I'm trying to set a duet in three stanzas.
In each stanza, one singer sings the first half and then both sing the
second half together.  I'm trying to put 'Singer 1', 'Singer 2' etc at the
start of the lyrics for each stanza, then 'Both' in half-way through, in a
way that doesn't count as a syllable and creates some extra space in the
notation.

Thanks for any advice.

Ah, of course, tags! Somehow I hoped that Lilypond had some hidden trick 
to achieve this automatically, but tags will work too. Thanks for the 
tip about the bar numbering: not in issue in this particular piece, but 
might be in other scores.


Thanks!
