Ah, you need to adjust the vertical extent in the other direction:
\markup \with-dimensions #'(0 . 0) #'(2.5 . 0)
\general-align #Y #UP "foo"
The vertical extents #'(0 . -2.5) and #'(2.5 . 0) both have the same
effective height of -2.5 units, however they have a different relative
starting point which is important for what may appear *below* the
markup. In my example, I needed the red rectangle to snugly fit with
the scores on both sides, so I apologize that it was not very clear how
the vertical extent had been altered to achieve that.
Also, do use \general-align to avoid futzing with \vspace in your
markup.

Excellent advice, thanks again.

On the other hand, it would be useful from time to time, and, as David has observed, both `\vspace` and `\hspace` accept negative values, which means that LilyPond is essentially ready to handle those cases. > Would it suffice for you to remove the global padding and manually > insert any spacing where it is needed as opposed to trying to remove > the padding in the spot where you do not need it? Yes, this will be the workaround I'm going to use eventually. Werner

I don't think so. The point of the Dynamics context is to align the dynamics
put into it on a common baseline. If there were another `^\markup ...` at the
point of that note with a ledger line, the alignment would force the first
markup to much higher (just add `s1 s1^"text"` in `MI` to see it). There is a
tradeoff between making the line of dynamics look like it's consistently above
the staff and not pushing it farther than necessary from the staff. I think
LilyPond's behavior here is legitimate, though perhaps the text script should
go higher than it does (with the ledgered note).

I am not yet sure if this is a bug or not.
However, I would like to hear about your actual use case. What do you want this

Perhaps `oddHeaderMarkup` will work better? This looks OK:

"foo"

top-system-spacing.minimum-distance = 0

I'd call it more of an inconsistency with regard to behavior of something for which (ly:stencil-empty ... #X) returns #t (namely vertical spacing). The behavior inside of markup itself is to space and pad the adjacent vertical elements as if the vertical spacing weren't there, then add the spacing. -- David Kastrup

What do > you want this for? I'm working on the visual index, and there is a place where markup is on the left, and a score on the right, but some lines of the score (via `InstrumentName`) reach into the markup. For example, lines 1, 3, and 5 on the left come from the markup, while lines 2 and 4 come from the score. Contrary to earlier versions, the new visual index will be split into two pages, and this special markup will positioned at the top of the second page. Previously, there was no problem in interweaving markup and space because it happened mid-page. However, moving it up as much as possible to the edge of the page doesn't work, as described in earlier e-mails. BTW, the reason to have no margin at all is to include the PDF as an image into the PDF version of the NR, making it as large as possible without exceeding the text height and width. As mentioned earlier I know how to work around the problem. It is just surprising that Aaron's solution works mid-page but not at the edge, and I would like to know the reason. Werner
Anybody else playing with GPT4 and Lilypond?
I've seen some examples of other people succeeding in getting ChatGPT with GPT4 to compose simple music in other text based music formats. I've had limited success getting it to output Lilypond code. It is able to correctly structure the code with a score block, nested contexts, and appropriately named variables, and bar checks at the end of each measure. It seems to struggle to create rhythms that fit within the time signature beyond extremely simple cases. It also seems to struggle a lot to understand what octave pitches will be in when using relative mode. It also seems to have a lot of trouble keeping track of the relationship between notes entered in different simultaneous expressions. Just asking it to repeat back which notes appear in each voice on each beat, GPT4 frequently gives stubbornly incorrect answers about the music it generated. This makes it very difficult to improve its output by giving feedback. I'm curious whether anybody else has tried playing with this. I have to imagine that GPT4 has the potential to produce higher quality Lilypond output, given some of the other impressive things it can do. Perhaps it needs to be provided with a large volume of musical repertoire in Lilypond format.
Re: Anybody else playing with GPT4 and Lilypond?
Hah yes. It once said \begn{music} and i said "are you making this up?"
"I'm sorry, you're correct. The start tag should be \begin{lilypond}.
Its super handy but you have to watch it. It can be a pathological liar. I
asked it how to do something on the Akai Mini Play and it said to use this
button On the upper left corner. when i asked for clarification instead of
admitting it was mistaken it said it was white and next to another button.
Twice it doubled down before admitting it was wrong.

I think that's been exaggerated. It's very good at generating
plausible-sounding text responses to prompts, everything else looks
cherry-picked.

Re: Anybody else playing with GPT4 and Lilypond?
HI Saul; I asked ChatGPT to write some ABC notation. The result was...'okay'. I then asked for a very simple arrangement of some children's tune and it got very confused about relative pitches. Since the rhythm for the piece of music I requested was so simple it didn't have a problem generating the score. I argued with ChatGPT about relative pitches in Lilypond, I told it to go back and read the manuals :-) I gave up asking ChatGPT about generating Lilypond scores after that.

For some real fun i asked it to generate code that a potential solution would be recursive (without suggesting a recursive solution). The first time I stumped it and it went off for two hours. I asked it again later and it camenback with an interative solution without getting stuck .

I think you may have that impression based on GPT3.5. GPT4 is already being
used to generate working non-trivial computer programs based only on a
brief text description.

Re: Anybody else playing with GPT4 and Lilypond?
I use chat.openai.com quite a bit for LilyPond. It almost never gives a correct or directly useful answer, but often gives me ideas where I can continue with LilyPond docs to figure out a solution. It's definitely good at explaining how code fragments work if you paste them in. This is a very similar situation to another esoteric language I use, OpenSCAD. These languages don't benefit from anywhere near the amount of training data that's available for languages like C++ and Python. That should improve over time, but for now it's a crap-shoot. Incidentally, I found Bing (supposedly based on GPT-4) is much worse than chat.openai.com, despite its ability to look up info on the web, and often just says it can't find anything.

Perhaps it needs to be provided with a large volume of musical repertoire in Lilypond format.
bookOutputName still gets "-1" suffix added to SVG file names
I've got to generate a thousand+ cropped SVG files with specified file names
from one lilypond compilation, so I'm wrapping each score in a \book with
its own \bookOutputName as in this MWE:
\version "2.24.1"
#(ly:set-option 'backend 'cairo)
#(ly:set-option 'separate-page-formats 'svg)
#(ly:set-option 'use-paper-size-for-page #f)
#(ly:set-option 'point-and-click #f)
\book {
\bookOutputName "Foo"
{ f' }
}
\book {
\bookOutputName "Abc"
{ a' }
}
\book {
\bookOutputName "Bar"
{ b' }
}
But the SVG files all have the extra -1 suffix as though there were additional
files from the same book that would collide:
32 -rwxrwxrwx+ 1 J None 32199 Mar 29 22:25 Foo-1.svg*
32 -rwxrwxrwx+ 1 J None 32190 Mar 29 22:25 Abc-1.svg*
32 -rwxrwxrwx+ 1 J None 32231 Mar 29 22:25 Bar-1.svg*
My MIDI files don't have this problem since they only add a suffix on
**subsequent** files with the same base name, and there's only one per book.
These "-1" suffices are messing with my URLs for the SVG files,
so I'd appreciate any ideas on how to get rid of them. Thx.
P.S. I get the same thing using 'backend 'svg
P.P.S I'm using Windows 10 Pro with Cygnus bash and Frescobaldi 3.1.1

Re: Anybody else playing with GPT4 and Lilypond?
re. "Anybody else playing with GPT4 and Lilypond?" I'm very much interested in exploring its use to generate graded sight-reading material. My own instrument is classical guitar and we're not the best sight-readers[1]... it would be nice to have daily sight-reading exercises generated for practice, with midi. I could donate the use of a QEMU/KVM server instance for working on a project of that sort. [1] Guitarist John Williams: "Another thing I’ve noticed in master classes, is that players will come on and play the most difficult solo works from memory, and yet if you give them a part to play in one of the easier Haydn String Quartets, as I often do, they’re lost in no time, and have a very poor sense of ensemble or timing. Guitarists are among the worst sight-readers I’ve come across. Julian Bream and I are both dead average sight-readers by orchestral standards, but among guitarists, we are [considered] outstanding!

They are there for good reason. If any of your `\book`s got output on multiple
pages, there would indeed be multiple files output.
If you never want separate pages, you should not use `separate-page-formats`
but `tall-page-formats`.
By the way, in addition to simplifying automation (like lilypond-book), having
`-1.svg` even on the first page makes it possible to use both
`separate-page-formats` and `tall-page-formats` at the same time.
