Defining new contexts

[Jim Long]

I'm experimenting with defining and using custom contexts.

I have not succeeded in applying the example at:

http://lilypond.org/doc/v2.18/Documentation/notation/defining-new-contexts

to my tiny example below attempting the creation of a custom
ChordNames context.  The '\new XChords' line throws a warning:

GNU LilyPond 2.18.2
Processing `foo.ly'
Parsing...
Interpreting music...
Preprocessing graphical objects...
Interpreting music...
warning: cannot find or create new `XChords'
Preprocessing graphical objects...
Finding the ideal number of pages...
Fitting music on 1 page...
Drawing systems...
Layout output to `foo.ps'...
Converting to `./foo.pdf'...
Success: compilation successfully completed


How can I modify the second score's source to have the scores
engrave the same in the output file?

Thank you!

Jim


\version "2.18.2"

\score {
  \layout {
\context {
  \ChordNames
\override ChordName.font-size = #12
} % context
  } % layout
  <<
\new ChordNames \chordmode { c1 }
\new Staff  \chordmode { c1 }
  >>
}


\score {
  \layout {
\context {
  \name XChords
\alias ChordNames
\override ChordName.font-size = #12
\type "Engraver_group"
} % context
  } % layout
  <<
\new XChords \chordmode { c1 }
\new Staff   \chordmode { c1 }
  >>
}

Try the following, comments inline:

\score {
  <<
\new XChords \chordmode { c1 }
\new Staff   \chordmode { c1 }
  >>
  \layout {
\context {
  %% copies settings from ChordNames
  %% No need to create a new context from scratch
  \ChordNames
  \name XChords
  \alias ChordNames
  \override ChordName.font-size = #12
}
%% let Score accept XChords, likely need to let it be accepted by other
%% context as well. I.e. do the same for Pianostaff, GrandStaff, ChoirStaff,
%% maybe more, have a look in engraver-init.ly to see which contexts
%% accept the default ChordNames
\context {
\Score
\accepts XChords
}
  } % layout
}

Ambitus placement

[Simon Albrecht]

Hello together,

I like to use the Ambitus_engraver in choral scores, but I often find it 
confusing to read, since the ambitus is printed before everything else, 
although its meaning depends on both clef and key signature. From the 
manuals or some snippet I took the idea to \set Staff.key-signature = 
#'() and thus have every non-natural note in the ambitus get an 
accidental, but the context property was changed (?) to key-alterations 
and now this doesn’t work any more.
Thus I’d like to place the ambitus just before the time signature, after 
clef and key signature. How can I do that?


Thanks in advance,
Simon

Tiny example:

\version "2.19.8"

\score {
  \relative {
\time 3/8 \key c \minor
es'8 g c
  }
  \layout {
\context { \Staff
  \consists "Ambitus_engraver" }
  }
}
%%%

Hi Simon,

This should get your part of the way towards what you want. It puts the
ambitus after the key signature, but produces an error and non-optimal
spacing. The property you need to change is BreakAlignment, which
determines the order in which these things appear. Hopefully someone else
can help with the error.

\version "2.18.2"

\score {
  \relative {
\override Score.BreakAlignment #'break-align-orders =
#(make-vector 3 '(left-edge breathing-sign clef key-cancellation
key-signature ambitus time-signature staff-bar cue-clef custos))
\time 3/8 \key c \minor
es'8 g c
  }
  \layout {
\context { \Staff
   \consists "Ambitus_engraver" }
  }

Hi Jim, Looks like Harm has you covered.  See also this snippet that shows
how to define a custom staff context:
http://lsr.di.unimi.it/LSR/Item?id=882

If you are generating midi files you will also need to define your context
for midi as well as layout, as shown in that snippet.  Otherwise you will
get warnings.

HTH,
-Paul

OK so the space-alist property is what needed changing. This should do what
you want

\version "2.18.2"

\score {
  \relative {
\override Score.BreakAlignment #'break-align-orders =
#(make-vector 3 '(left-edge breathing-sign clef key-cancellation
key-signature ambitus time-signature staff-bar cue-clef custos))
\override Staff.KeySignature.space-alist =
#'((ambitus extra-space . 1) (time-signature extra-space . 1.15))
\override Staff.Ambitus.space-alist = #'((key-signature extra-space .
1))
\time 3/8 \key c \minor
es'8 g c
  }
  \layout {
\context { \Staff
   \consists "Ambitus_engraver" }

Thanks a lot, Kevin. That did it.
I further modified it to avoid the

programming error: No spacing entry from Item to `time-signature'

and included the other entries present in the default, so it now reads 
as in the attachment.

Right brace problem

[William Marchant]

Hi,
I want to bracket the three verses of a song, and follow with a single 
line of words that make up a chorus.  The following code puts the 
bracket in, but the bracket takes up a beat in the music as shown below; 
thus the chorus words are all out by one beat.  Is there a solution to this?

Re: Right brace problem

[Br. Samuel Springuel]

Someone provided me with the following trick for inserting a asterisk 
that doesn't occupy a note in lyrics:


aster = \set stanza = \markup{"*"}

Then I just place \aster between the words where I want the asterisk to 
appear.


Perhaps that can be adapted to your case (without compilable code I 
can't test).

Re: Ambitus placement

[Simon Albrecht]

Well, applying this on a multi-line score showed some defects still 
(resulting in a giant heap of programming errors), so I updated the 
information from the IR directly and now it should work for all 
conceivable cases without errors.

Learning by doing ;-)

Thank you.  But if I have to do all the \Score \accepts stuff,
then I guess I don't understand what '\alias ChordNames' does in
your example.  I'd like to find a simple way of declaring that
"my custom context X is just like built-in context Y, except that
it modifies these settings."  The appeal of that goes downhill
quickly if there are loose ends that have to be tied back into
Lilypond internals.

Is there a way I can define a context based on ChordNames and
have it automatically inherit all of the properties of a
ChordNames context, except the ones that I specifically change in
my custom definition?  In other words, a way to eliminate the
need for the second \context {} block in your example?

If I understand correctly, it allows your new context to accept any commands 
that a \ChordNames context does.

Yes: don’t give it a new name.  ;)

Tempo spanners

[Dominic]

(Lilypond 2.19.15)

Dear all,

As you can see from the image and the attached file, I have achieved an
independent text/tempo spanner by creating a special context containing only
the spanner and letting the Score context 'accept' it. I only understand
this technique about 70%, as I hacked it together from snippets I found
online.

Unfortunately, the "rall..." line is 'sitting' on top of an invisible line
created by the existence of the metronome mark. (Removing the metronome mark
allows the spanner to 'fall down' nearer to the staff.)

How can I get both the metronome mark and the tempo spanner to be
interpreted on a single line in the Score context AND still have full
independence of text spanners within individual staffs?

A crude and forced temporary solution would be to do
Score.TextSpanner.Y-offset = #(negative number) on a case-by-case basis, but
in a real-life situation this would not be practical (I am working on an
orchestral score with thousands of bars which needs to be robust)

Any help or insight would be greatly appreciated!

Thanks,

Dominic

I think your problem probably is in your newly-defined ScoreSpanner. Are
you sure you need to create a new context just for the tempo marks? I was
able to get the behaviour you wanted by simply using a Dynamics context
instead.

i.e. replace
\new ScoreSpanner { \tempoMarks }
with
 \new Dynamics { \tempoMarks }
and it should work.

If for some reason you really do need your own context then I'd say you
need to add some more options/properties to the one you defined.

Hi Dominic,

> Thanks, Kevin - that appears to work perfectly! 

Hmmm… When I try it, in the second score, the baselines of the tempo mark and 
the “rall” are not consistent.
Is that actually what you want?

Cheers,
Kieren.

Re: Tempo spanners

Anyway, it would be more confortable to have a "TempoTextSpanner", as
proposed in this issue:

I had a brainstorm -- the problem is SkipMusic which isn't handled
anywhere.  But we can use a SkipEvent instead, and it all works!!!

Durations occuring on their own within a music sequence

[Flaming Hakama by Elaine]

%{

Hello, all.

I found an unexpected behavior when using the new feature:
"Durations occuring on their own within a music sequence will take their
pitches from the preceding note or chord."

At least, it was unexpected by me.
Is this repetition of the cautionary accidental by design?

It seems to only occur when used within a chord.
When used with a single note, the accidental is not repeated.

%}

\version "2.19.15"

\relative c' {
r2 r4 fis | g4.^"ok as note" f?8 ~ 2 |
r2. fis4 | 4.^"? with chord" 8 ~ 2 |
r2. fis4 | 4.^"the old way" 8 ~ 2 |
}


Thanks,

David Elaine Alt
