Order of process-music between Contexts

[Saul Tobin]

Hi all,

I'm trying to figure out the workings of engravers and contexts. Can anyone
point me to the relevant code, or better yet explain the order in which the
process-music step happens between engravers in child vs. parent contexts?
Is this set in stone, or can it be modified? Like, suppose I have a custom
Scheme engraver in a parent context, which uses process-music to set a
property that must then be read by an engraver in child context during its
own process-music. Is that possible to do? Or am I thinking about it
wrong/is there a better way to go about it?

I'd really appreciate some pointers here. Thanks!

Saul

Re: Emacs lilypond mode formatting and indenting

[Andrew Bernard]

Hi Caio,

For 2.19.82 refer to Section 4.1.1 Configuruing the system. It explains
what to do to enable point and click from the PDF viewer program, and how
to set the EDITOR variable to make emacs go to the right line and column. I
don't think it says it there and assumes you know what you are doing, but
running emacsclient for this means yo have to start emacs with
(server-start) in the init file. That's documented on the Emacs Wiki.

Start emacs, then open the PDF and click on an object. The source file will
open in emacs at the precise location. It's great!

Works splendidly on Debian 9.

Andrew

Greetings,
you probably need to add a Dynamics context above your staff and your
lyrics. You can fill this context by typing all your dynamics in it,
with spacer rests for example:

\new Dynamics { s1\p s1\< s1\! }

… Or if you have already entered all your dynamics with the notes, you
can just prevent them from being printed below (or above) the staff by
removing the engraver linked to your Voice, and just use the same
music in the Dynamics context (where the notes won’t be printed, only
the dynamics). Here’s an example:

%%%

music = {b1\< b\> b\p}

<<
  \new Dynamics \music
  \new Staff = "staff" \music
  \addlyrics {
\set Lyrics . alignAboveContext = "staff"
bla bla bla
  }
>>

\layout {
  \context {
\Voice
\remove Dynamic_engraver
  }
  \context {
\Dynamics
\remove Script_engraver
\remove Text_engraver
  }
}

%%%

Cheers and good luck!

Nope, it turned out to be a lot more idiotic: I was modifying the
'octavation property of some notes… then not taking that into account
when sorting the pitches. (And, as David noted, I was displacing the
pitches onto the notes without moving any articulations they might
have attached.)

Here’s the new updated function, now it sort of works!

Invisible notes changing how width a staff is printed

[Klaus Ethgen]

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA512

Hi,

Currently I have the problem that I set a partitur with guitar cords
only visible as ChordNames and FretBoards. I use `\set chordChanges =
##t` to only set the name and fret board when the cord changes.

For the begin I use the full takt size as note size (in 2/4 = half
notes). That was looking good but then I changed the cords to encode the
takt I use with the guitar. (e2:m -> e4:m e8:m e:m) to have the correct
voice in MIDI.

Unfortunately, after that the staffs are broken into more lines than
possible.

Any help is appreciated.

Here is the relevant snippet:

Yes, that is exactly what I was looking for, thanks very much! My next
problem is that this now overlaps the staff instrument names. I could fix
this with a bigger indent in the \paper block, but changing the left-margin

at all. I'm going to have to dig into it a bit.

you might try something like this:

Rotated StaffGroup InstrumentName?

[N. Andrew Walsh]

Hi List,

quick general question:

if I have a StaffGroup, like this in my score:
--
\new StaffGroup = "Staff_soloists"
<<
  \new Staff = "Staff_oboe_solo" <<
  \global \exTwoOboeMusic
>>
  \new Staff = "Staff_guitar_solo" <<
\global \exTwoGuitarMusic
  >>
  \new StaffGroup = "Staff_percussion_solo" \with {
systemStartDelimiter = #'SystemStartSquare
instrumentName = #"Perc. Solo"
shortInstrumentName = #"S.Prc."
  }
  <<
\new Staff = "percSoloOneUpper" <<
  \global \exTwoPercSoloOneMusicUpper
>>
\new Staff = "percSoloOneLower" <<
  \global \exTwoPercSoloOneMusicLower
>>
  >>

   \new Staff = "exTwoCbsSolo" <<
  \global \exTwoBassSoloMusic
>>
>>
---
Is there a way to put the group InstrumentName for that whole group, but
rotated 90°? This is something that would be useful, for example, in a
piece for orchestra with both chorus and soloists, or a concerto with more
than one soloist (in this case, these are four soloists within a larger
ensemble. The content is in a separate file, triggered by the variables,
and \global defining Staff settings).

What I would like would be for the toplevel StaffGroup "Staff_soloists" to
have a name, rotated 90° and extending to the left of the individual
instrument names. Is there any way to do that?

Cheers,

A

I have a computer repair shop. In my experience, it will be very hard to 
beat eBay for repair parts like this. Sometimes we have tried to buy 
parts from manufacturers, and even they told us to use eBay. Once a 
product is discontinued, they would usually far rather sell a new one 
than help fix an old one, and can't be bothered to keep in stock every 
part for every model ever made. But if the new machines have moved away 
from some near-Platonic-Ideal condition the old one had, repair might 
still be the way to go.


Several suggestions for parts sent privately.

Ok, in that case any glossyness wouldn't be of any concern. I'd say that
the inkjets (for sheet music) isn't suitable for prepress. They have
simply put to low resulotion. I'd be happy with the Kyocera for
prepress.

Hi Karl,

That was in response to David's point about inkjet images not being
waterproof or durable under handling, that's all. I thought you may be
preparing pages for pre-press work perhaps, in which case the paper is
handled with great care, or even being careful not to touch. Though
nowadays most prepress then goes straight to press without intermediary.

Aren't all prints "handled" ?

And I do want high quality printouts, regardless if they are for my 
own choir or for sale or for whatever reason.

Would a photographer be satisfied with printouts from a run of the mill
colour laser ?

Why should I expose singers and players with subpar sheet music, aren't
we artists of producing beautiful sheet music. There is no reason to
degrade your results by using, in the end, a bad printer.

I have a Minolta-QMS PagePro 9100 which I like wery much.
It would need a new network card: art.nr 4128-6055-01,
and a "paper take-up roller of the multi-purpose paper tray" (1710502-001 CRU).

I'd be fine for a printer in the 1000-2000 EUR price class.
My last printer was the Kyocera and it cost 2500-3000EUR.

I think that have been discussed elsewhere before.

Let's say I like postscript, I do some programming in it from time to 
time, I like the results I get with it, and I'm kind of tired of 
converting what I have just because the printer is too stupid to 
understand it. If possible I require all printers I buy to have 
postscript, the exception is large format inkjets.

As I wrote before, the HP pagewide and the Epson WF-C8190DTW do give my
perfect matte blacks, but they have problems with the resolution, the 
black edges are not straight. The blacks don't cover the whole black
area, there are small white dots all over where the the ink didn't get.
The Epson is a litte better.

Yes, I have their SC-P800 A2 printer, and I'm still having trouble to 
get it work, tried with gutenprint so far but only gets a cryptic
error code 0x1A36. The handling is really really subpar compared to
my usual postscript printers.

If you have any advice to get it working I'd be glad.

My only intent with it is posters, photos, covers, and large sheets of
music for organ works and such where you don't have a hand handy to
turn the page.

Sending it to the printer gave me a surplus of waste paper - so I kind

There are definitely users of Emacs and LilyPond who would not switch to
Frescobaldi anyway.  If you can improve Emacs in that area, it will be
appreciated whether or not the result turns out good enough to make
current Frescobaldi users switch (and it seems that whatever usability
issue causing a slowdown like that may be around, offering an option for
switching it off would seem more welcome like a wholesale switch to
most).

Uh, the resolution is where it aims, not where it hits and the ink

Re: select a note in a chord

Hi Valentin and everybody.

So, now the chord name is preserved when \dropNote or \raiseNote is 
applied once, but not when is applied twice or more.


It reminds me something that happens when a variable in lilypond is 
called with $ instead of # , but in scheme I don't see this difference.


Could it be something like that?

BTW I prefeer \riseNote instead of \raiseNote .

Hi Urs,

I split my score into files only ten pages long to avoid the issue to 
begin with, but it suddenly started happening. Perhaps some Debian 9 
Python change?



Other than with LilyPond the issue is not the complexity of the *score* 
but that of the *input files*, which correlates typically but not always.


I had this problem with two projects: one was a huge (150 page) 
orchestral score that was organized in >5.000 input files, the other had 
very short 2-3 page songs with one large input of several thousand lines 
each because (from auto-converted input) every element had a "\tweak id".


The basic error here in Frescobaldi's code is that (I think) upon every 
change the whole document is parsed again (following all includes) to 
provide the data for autocompletion and syntax highlighting. As this 
happens in the single application thread this is blocking everything else.


Essentially there should only be two (minor) things to be done to 
completely and instantly make the problem go away:


 * Make sure that the used data structure is only updated in the background
 * Make sure only *modified* parts of it are updated

While this is conceptually pretty clear I haven't dared yet to 
investigate it in the code base yet because I haven't understood yet how 
Frescobaldi actually does its highlighting. But I recently changed the 
way Frescobaldi handles external jobs/processes, and that might make it 
more straightforward and compartmentalized to approach the issue.


I can't afford starting this but if you (well, or anyone else) would be 
interested going after it I'd certainly be there to assist.

I would also think that this problem is *not* related to a change

files. The issue Federico links to is exactly the problem.

Fixing this issue should be comparably low-hanging fruit, especially
with some new code providing better control over external background
jobs. So maybe tackling *this* would give you earlier results ;-)
