Here's the section on equality (eq? eqv? and equal?):
https://www.gnu.org/software/guile/manual/guile.html#Equality

I've found the guile manual to be a helpful resource for learning to use
Scheme.

Re: lilypond-user Digest, Vol 142, Issue 80

Hi, Jay--

i'm not sure of everything you're trying to do, but change your layout block to
this:

\layout {
  \context {
\Voice
\remove Note_heads_engraver
\remove Rest_engraver
\consists Completion_heads_engraver
\consists Completion_rest_engraver
  }
  \context {
\Staff
\remove Time_signature_engraver
  }
}

You'll get rid of all time signatures--err, at least i did, and i'm not the most
advanced user.  You can also erase your \override command for the time
signature.

i recently used the compound meter.  i thought that Lilypond added the "in
between" barlines by default and used bar checks inside the compound meter, only
to find that i was getting time signature errors when compiling the file.  The
output didn't have any of those "in between" barlines, so i deleted the bar
checks and added the missing lines manually.  i did this all in my music
variable.  i suspect there is a way to get Lilypond to change its default
behavior and add those barlines, itself, but as i said, i'm not the most
advanced of users.  i hope this little bit helps, though.

Take care,
bill

Perhaps it's your choice of comparison by eq?  I can't say what it does
with strings, but it generally tests that an object is the same object as
another, rather than simply equivalent.  (If you want more on these, you
can read up on them in the Guile manual).

string=? seems to work.  Try the following--is it what you want?

 #(define (myNoteNames size nsiz)
   (lambda (grob)
 (let* (
 ;; bindings
 (default-name (ly:grob-property grob 'text))
 (new-name (assoc-get default-name newnames))
 (cause (event-cause grob))
 (duration (ly:prob-property cause 'duration))
 (duration-log (ly:duration-log duration))
 (suffix
  (case duration-log
((1) (if (= nsiz 1)
 (if (or (eqv? new-name "R")
 (eqv? default-name "b"))
 "i"
 "a")
 "")) ;; half note
((2) (if (= nsiz 2) "a" "")) ;; quarter note
((3) (if (= nsiz 3) "a" "")) ;; eighth note
(else "")))
 (suffix2
  (if
   (or (string=? default-name "b")
   (string=? default-name "d"))
   "i"
   ""))
 (text (string-append new-name suffix suffix2))
 )
   (display default-name)
   (display (eq? default-name "d"))

Re: Programming Question

[Jay Vara]

> I am not top-posting

David,

I defined a second variable nsiz which is 1, 2 or 3 

Tried

(case duration-log
 ((nsiz) "a" )
  (else "")))

This condition was never succeeding although I printed out nsiz and 
duration-log and they were the same.

Then I changed it into an if statement - that worked. This is to add a 
suffix to note name for half notes in normal duration, quarter notes in 
halved durations, and eighth notes when durations are further halved. It 
should be obvious from the output that it has worked. 

Then further, I wanted the suffix to be "i" if the note was d or b. I 
tried various if statements and they are all failing for some reason. 
default-name which is equal to "d" gives a #f when tested, for example.
Not sure what to do to make it work.

Here is the code:

\version "2.18.2"

music =  \relative c' {d2 b2 b4 d} % {c4 d2 e f g2 g a4 b c c b a g f e 
d c}

Re: Automatic fixing of note between measures

[David Bellows]

>Is there a reason not to use Completion_heads_engraver all the time or

I think the expectation is that most composers most of the time do not want
notes split up automatically as it probably means a mistake was made when
entering the notes. Basically they'll split when they want to. It's just
you and I working with generated scores where this other behavior is
preferred.

>I am also using a compound metre. Hopefully this will work with that.

I have no idea about that! For me I'm just using the bar lines and
automatic breaking more for aesthetic reasons or as a help to the performer
to see where they are than I am for any musical reasons. So for me 4/4 is
all I'm using. Naively I would assume that it should work for more complex
time signatures.

>In one case I have repeating measures of 5/4 + 3/4 + 2/4. I have succeeded
in getting the bar lines printed after 5th and 8th quarter notes in a 10/4
time scale by adding a voice with bar lines at those places. May be there
is a different method of achieving this effect.

I'm not quite getting what you're trying to do, do have a picture or some
code?

Fantastic!

I can not claim to understand what you have done. The display command is

Just insert this outside of the let block (and before the last expression

(display text) (newline)

You can do fancier things with format:

(format #t "default name: ~a new name: ~a~%" default-name text)

You should see the output in the log.

compoundMeter - how to get lilypond to recognize the bar line in the middle

[Jay Vara]

>I am not top-posting

I am using a compoundMeter - 5/4 + 2/4. I would like to see a bar line 
after 5 quarter notes (and after 7 quarter notes). Plus I would like 
Completion_heads_engraver to recognize the bar line after the 5 quarter 
notes.

I was able to artificially achieve getting the bar lines by adding a 
silent voice with those bar lines.

However I was not able to find anything that would make the fifth note 
g2 in the following example to be automatically replaced by g4~g4 [tied 
quarter notes] as happens for the seventh note where a2 is replaced by 
a4~a4.

Also, in the code below, I tried to prevent the time signature from 
printing - does not seem to work for compoundMeter. Also not sure why I 
got a couple of extra staff lines, plus how it got the 7/4 meter for the 
extra staves.

\version "2.18.2"
fooBar = { s1 s4\bar "!"  s2 \bar "||" }
music =  \relative c' {c4 d e f g2 a b4 c c b a g2 f4 e d c b a g a b}
\score {
  
  <<
   \override Staff.TimeSignature #'stencil = ##f 
   \compoundMeter #'((5 4) (2 4) )
\set Timing.beatStructure = #'(5  2 )
   
\new Voice = "theBarLines" { \fooBar \fooBar \bar "|." }
 
 \new voice \music   
 \shiftDurations #1 #0 {\music}

  }

The point is that LilyPond doesn't recognize medium font-series. When you set

David,

That works. Malte also suggested something similar. 

Is there a reason not to use Completion_heads_engraver all the time or 
atleast as a default?

I am also using a compound metre. Hopefully this will work with that.

In one case I have repeating measures of 5/4 + 3/4 + 2/4. I have succeeded 
in getting the bar lines printed after 5th and 8th quarter notes in a 10/4

Re: Automatic fixing of note between measures

[David Bellows]

The project I'm working on right now also automatically generates music and
I ran into the same problem. Here's what my software automatically
generates now to deal with it:

\score {
  \new PianoStaff <<
\new Staff = "upper" <<
\new Voice = "first" \with {\remove "Note_heads_engraver" \consists
"Completion_heads_engraver" \remove "Rest_engraver" \consists
"Completion_rest_engraver"}
\voice_one  >>
\new Staff = "lower" <<
\new Voice = "second" \with {\remove "Note_heads_engraver" \consists
"Completion_heads_engraver" \remove "Rest_engraver" \consists
"Completion_rest_engraver"}
\voice_five  >>
>>
  \layout{ragged-bottom = ##t ragged-right = ##t }
}

What you're looking for is the stuff starting at "\with {\remove
...\consists "Completion_rest_engraver"}

This is a lifesaver.

David,

You are way too good!

Is this the way I enter it? For some reason, does not seem to be working 
- it seems to be ignoring the suffix.

If I wanted to display new-name as the program runs, is there a command 
for that?

Thanks

Re: Programming Question

[Jay Vara]

David,

Wow! The power of programming knowledge! Yeah, size can be set based on 
duration. In my particular case, this is giving some unwanted effects 
since the duration of all my notes are not the same (unlike in the small 
example I made up for this post). So I will be using your earlier 
suggestion.

On the other hand, what would be nice is if the NoteName could be changed 
based on duration. In particular, if the note is a half note, I would like 
to add a character (say a "-" or a "a") to the note name. This could be 
more involved probably.

Yay! I tried the "cryptic" version you suggested, and it works nicely. The

When lilypond displays an error, is it possible to know which line of code

Here's how you could add an argument for 'font-size to your function:

 \version "2.18.2"

music =  \relative c' {c2 d e f g a b c c b a g f e d c}


newnames =
#`(("c" . "S")
   ("d" . "R")
   ("e" . "G")
   ("f" . "M")
   ("g" . "P")
   ("a" . "D")
   ("b" . "N")
   )

myNoteNames =
#(lambda (size)
   (lambda (grob)

 (let* (
 ;; bindings
 (default-name (ly:grob-property grob 'text))
 (new-name (assoc-get default-name newnames))
 )
   ;; body
   (ly:grob-set-property! grob 'text new-name)
   (ly:grob-set-property! grob 'font-size size)
   (ly:text-interface::print grob)
   )
 ))

#(define (myNoteNames size)
   (lambda (grob)

 (let* (
 ;; bindings
 (default-name (ly:grob-property grob 'text))
 (new-name (assoc-get default-name newnames))
 )
   ;; body
   (ly:grob-set-property! grob 'text new-name)
   (ly:grob-set-property! grob 'font-size size)
   (ly:text-interface::print grob)
   )
 ))


\new Staff {
  <<
\new Voice {
  \music
  \shiftDurations #1 #0 {\music }
  \shiftDurations #2 #0 {\music \music }
}
\context NoteNames {

  \override NoteName.stencil = #(myNoteNames 1)
  \music

  \override NoteName.stencil = #(myNoteNames -2)
  \shiftDurations #1 #0 {\music }

  \override NoteName.stencil = #(myNoteNames -4)
  \shiftDurations #2 #0 {\music \music }

}
  >>
}

%%
Notice that I've given two versions of myNoteNames.  They are equivalent.
 (I find the second easier to use, but maybe that's just me.)

Now, if you want to have LilyPond detect the note durations and make the
fontsize decisions for you, I don't believe you'll be able to use the
NoteNames grob as it stands.  It would be nice if a NoteNames object had a
pointer to a NoteHead, from which information like duration could be
gleaned, but it doesn't.

Hope this helps.

I am using NoteNames context to print the note names automatically for 
scales of half notes, quarter notes and eighth notes. I have redefined 
the NoteNames using override NoteName.Stencil.

I need different font sizes for the note names of half, quarter and 
eighth notes. Currently I have got this working by using three different 
versions of the myNoteNames function. The only change between them is 
the fontsize of text. Is there a way to combine the three functions - 
perhaps have two arguments. I tried this and since the syntax of 
defining the function and of using it were not clear, I was not able to 
get it to work.

Here is the code:

\version "2.18.2"

music =  \relative c' {c2 d e f g a b c c b a g f e d c}
  
  
newnames =
#`(("c" . "S")
   ("d" . "R")
   ("e" . "G")
   ("f" . "M")
   ("g" . "P")
   ("a" . "D")
   ("b" . "N")
   )
   
  
myNoteNames =
#(lambda (grob)
   (let* (
  ;; bindings
  (default-name (ly:grob-property grob 'text))
  (new-name (assoc-get default-name newnames))
 )  
  ;; body
 (ly:grob-set-property! grob 'text new-name)
 (ly:text-interface::print grob)
 )
   )
myNoteNamesS =
#(lambda (grob)
   (let* (
  ;; bindings
  (default-name (ly:grob-property grob 'text))
  (new-name (assoc-get default-name newnames))
 )  
  ;; body
 (ly:grob-set-property! grob 'text (markup #:fontsize -2 new-
name))
 (ly:text-interface::print grob)
 )
   )

myNoteNamesT =
#(lambda (grob)
   (let* (
  ;; bindings
  (default-name (ly:grob-property grob 'text))
  (new-name (assoc-get default-name newnames))
 )  
  ;; body
 (ly:grob-set-property! grob 'text (markup #:fontsize -4 new-
name))
 (ly:text-interface::print grob)
 )
   )

\new Staff {
  <<
 \new Voice {
   \music 
 \shiftDurations #1 #0 {\music } 
 \shiftDurations #2 #0 {\music \music }
 }
\context NoteNames {
  
  \override NoteName.stencil = #myNoteNames
\music 

   \override NoteName.stencil = #myNoteNamesS
\shiftDurations #1 #0 {\music } 

\override NoteName.stencil = #myNoteNamesT
\shiftDurations #2 #0 {\music \music }

}
  >>
}
