Hi Kieren,

Well obviously I couldn't use your suggestion because I'm a total idiot!

Thanks for your help. Much appreciated.

All the best,

edition-engraver commit error (was Re: Edition Engraver tweak error)

[Jan-Peter Voigt]

Hi Craig,

Kieren already answered, but I want to assure that you where not caught 
by I mistake I made on Monday: There is a commit that ought to be in its 
own branch for development that accidentally disabled overrides. So 
please do switch to the previous commit (Feb 1 "issue #19") if this is 
the case.


I am sorry for any inconvenience for any user of the edition-engraver!

I repaired the repository, so any users that did not pull between Monday 
5. Mar 21h CET and 7. Mar 8:30h CET should not be affected by this mistake.


Best
Jan-Peter

The Notation Reference (at 4.3.1) suggests:

For line breaks at regular intervals use \break separated by skips 
and repeated with \repeat.
For example, this would cause the following 28 measures (assuming 4/4 
time) to be broken every 4 measures, and only there:

<<
  \repeat unfold 7 {

I assume you’d want to use a MultiMeasureRest (i.e., R2.), and override the 
stencil to look like you want it to.

Hope that puts you on the right path!

Moving the cursor like that can also loose the instrumentation.  Instead
of midi's interpretation of the correct orchestration you end up with an
anodyne piano-ish sound.  Much, very much, better than nothing, but
annoying on occasions.

Can't ignore-collisions on a tuplet

[paolo prete]

Hello,

in the below snippet I would like to keep the same distance between all the
notes of the 2/6 tuplet.
Instead, e' and e' in \voiceOne have a bigger distance because of the note
between them, in \voiceTwo.
How can I avoid that?
No problem if there will be collisions.

I tried to set several ignore-collision properties (  \override
NoteColumn.ignore-collision = ##t, \override NoteHead.ignore-collision =
##t, \override Ste.ignore-collision = ##t ) but the result is the same...

Thanks

I suspect this is just because failed assertions now make LilyPond abort
with an error message and you previously ignored them (which was almost a
given since distributed binaries of LilyPond completely omitted them).

Hi Omri,

There is no dead-simple, built-in way… but there are many ways of accomplishing 
what you want, each with pros and cons depending on exactly what functionality 
and flexibility you want.

For a constant number of measures per system, my favourite is David K's 
\bar-keeper, which I’ve shown in the snippet below. 

(Aside: I’m not sure why this isn’t in the main base code… Given that David K 
coded it, I imagine it’s the most elegant solution possible to the problem he 
was tasked to solve. And it is a function that many, many users would 
appreciate having access to.)

Hope this helps!

I second Andrew's suspicion that it is not related to Frescobaldi at all. If 
Frescobaldi fails you would either get an error pop-up or in severe cases the 
Window might disappear.
If you can read about an error in the log window it's most likely a LilyPond 
error.

Please compile your files directly using LilyPond from the command line, then 
report what is happening.

RE: Frescobaldi sudden failures on all machines

David

Nope I did not ignore any previous error messages. Something about Windows
10 and file permissions may be at the root. I had to run Fresco with
Administrator Privileges in the past. One possibility that may shed some
light is that I have installed Kaspersky Secure connection on both machines
just before disaster struck (just to watch football).

I have since re-installed Lily  from an old 2.19.56 installation package
followed by Fresco again. This time when I run Fresco a new popup appears
"running Lilypond this could take some time - nothing else happens.

I will try running from a command prompt but as it stands "Lilypond does not
exist" is the response.

Re: Frescobaldi sudden failures on all machines

Hi Peter,

I'm not at all an expert on any of this (or even really competent) but some
quick googling returns this thread:
http://lilypond.1069038.n5.nabble.com/Strange-return-code-and-compilation-fail-td145362.html

where they say that error is an access violation from within Lilypond (ie,
it's not Frescobaldi).

If it's happening on old .ly files, have you tried running convert-ly on
them? Have you tried creating a MWE just to make sure your Lily is working
at all?

HTH,

A

Frescobaldi sudden failures on all machines

[peter.gentry]

I have been using Frescobaldi for years but today re-running old files I see
the following behaviour.

 

The compilation proceeds for a while then halts with error -1073741819. This
happens on two different Windows 10 machines with different OS versions. It
happens when attempting to recompile old .ly files.

 

Frescobaldi error messages are notoriously obscure.  I have uninstalled ad
re-installed Frescobaldi and rebooted to no effect.

 

Does anyone have any suggestions to isolate this issue. I suspect it may be
about file permissions but that is just a suspicion.

Yes, you can move the frescobaldi midi player cursor (with the mouse) at
the position you like BUT each time you re-compile you lost the position
and you have to set it again it is doable but not practical. What I
personally do is to comment out the part of the score I don't want to
listen.  So, it would be great to be able to set the score begin to a

Re: Change the duration of a chord defined as a variable

[paolo prete]

David,

I wonder if is there another solution for obtaining the same result,
because the discussed one is too much unstable. Here's the template, below.
I googled how to change a chord duration, but I found nothing.




chord = 4 -> \mp

newChord =
{
  %  add \chord with a new fixed duration and with its articulations
}



I was thinking about taking the articulations from each NoteEvent of the
chord, iterating with a (map (lambda (x) ), and putting them into a new
list, but it seems overkill to me...
What do you think?


Thanks for your help

I was more thinking of \thevoice and \thelyrics here but indeed no
variants of that work.  Not really sure just what the function of the
"scopes" for books and bookparts as established in lily/parser.yy
actually is.

It works in master in that \mp ends up in the expression, but indeed it
does so as a note articulation rather than a chord articulation, and
LilyPond just drops \mf on the floor in that position.  Sorry for that.
At any rate, try

\displayMusic  \mp

in order to see the structures being used.  Working with \displayMusic
should help getting more of a clue about what happens here.

You may be right. But still, *sometimes* I use such a function for files 
which are included and which *might* throw an error otherwise.



Now books and bookparts actually have a \header with associated scopes.

That might look like this?

\bookpart {

thelyrics = \lyricmode { la la la la }
  }
  <<
\new Voice = "heinz" { \headerVal thevoice }
\new Lyrics \lyricsto "heinz" { \headerVal thelyrics }
  >>
}

This might be useful and essentially lead to something. Now, I am used 
to my own toolchain and prefer delegating score- and bookpart-creation 
to music- and scheme-functions. And I really don't like using the header 
for content. (Btw. I didn't follow the whole thread so maybe nobody was 
asking for that)

Take a look at the PDF.  They are there.  And I'd suggest using

\displayMusic

on music expressions you want to see analyzed.  "display" is unreadable
in contrast.

Have you even tried what happens with articulations?

Asking LilyPond should is usually the proper first recourse since it
means you waste only your own computer's time.  As a bonus, you get no

Re: bookparts

[Jan-Peter Voigt]

Hi all,

in this mail the thing with defining variables inside of curly brackets 
popped up the first time in this thread - so I hook here. (If it was 
mentioned in the former mails it doesn't matter ;-) )


IISC a major change to the codebase would be needed to allow something 
like this: \bookpart { music = { c''4 } { \music } }

but there are a lot users who would like to use it this way.
I don't want to talk about scopes and coding style, but want to show how 
I deal with it:
Using void-functions is a great thing because the can be called 
anywhere. So if you want to define something inside a file that is to be 
included inside curly brackets you can use a function like this:

--
\version "2.19.80"

def = #(define-void-function (sym val)(symbol? scheme?)
 (ly:parser-define! sym val))

\bookpart {
  \def music { c''4 } % this might be part of an included file
  { \music }
}
--
(In lily stable (<2.19) you have to add the parser and location arguments)

Still we have the global scope (OK, I do talk about scope) of the 
current parser. Now if you want to use some kind of templating mechanism 
you have two competing needs for the variable names. One approach to 
create templates is to prepare files to include which use well-named 
variables. For the piano the file might reference the variables 
piano_left and piano_right which have to be assigned beforehand. My 
first scores where for choir. So I was looking for a more flexible 
templates and I started to write music-functions which store the music 
in a tree so that my template functions are called "inside" or "on" a 
base branch. The branches of the tree are the scopes in which the 
template functions are called. This has the advantage that I can define 
several pieces of music with several instruments and then can quite 
easily create a book with several pieces all with there own 
instrumentation. You can have a look on the result here: 
https://github.com/jpvoigt/lalily-templates

(I am going to move this OLL-module to the OLL-GitHub-organization)


These are some very rough and quite unstructured thoughts ...
To conclude:
1. defining variables with music- or void-functions is a way to overcome 
the obstacle of defining variables only on the top-level
2. if the store behind the function allows for hierarchical storage 
templates (files or functions) can make use of a scope that is not on 
coding but on a semantic level ... or the like. This should be reworded 
somehow - I hope you get what I mean.

\version "2.18.0"
chord =
#(define-music-function (parser location dur) (ly:duration?)
#{  $dur #})

For recent 2.19, you can leave out the "parser location" blurb.

I am not sure whether this kind of usage might be common enough to
warrant creating an \etc syntax for it, like

chord =  \etc

{ \chord 8 }

It might actually be desirable for guitar chord variants outside of
\chordmode.  Or even in \chordmode.
