Re: Bundling Lilypond with project
So I'm looking at the download page and I don't see any downloads for the 2.23 binaries. Am I missing something, or do I need to compile them myself?

Coloring just one note in a chord
I have a basic staff defined like so:
\version "2.22.2"
\language "english"
\new Staff {
\key c \major
\clef treble
\numericTimeSignature
<
f'
g'
d'
>1
\bar "|."
}
I want to make the g' note head colored in green, but if I try this, I get
syntax errors about an unexpected \override:
\override NoteHead.color = SeaGreen
\override Stem.color = SeaGreen
g'
\revert NoteHead.color
\revert Stem.color
What am I doing wrong?
Thanks,
Felix
Re: Bundling Lilypond with project
Awesome! Thank you! I've heard about the Cairo backend, but I kind of stopped once I found out I'd have to compile Lilypond on windows, mac, and linux myself. I have a windows machine, a linux VM, and a hackintosh, but even then the process seemed very in-depth so I gave up. However, I'm glad to hear that the release is approaching. Thank you so much for all this information. I also didn't know that 2.23 was static.

Bundling Lilypond with project
Hello, I'm making a python application that uses LilyPond, but in order to make it completely portable, I need to bundle LilyPond with my application. It's licensed under GPL, so if I'm reading this right I should be able to do that as long as I make my own project GPL (already done). I just want to double check I'm correct, and if I am, how can I minimize file-sizes when it comes to distributing the binaries? All I use is the lilypond command to compile a ly file into an SVG, none of the other bundled tools. Thanks, Felix

Ohhh, I missed the part about Cairo not working for cross-compilation yet. My bad.

Ah, I had to install a C compiler. I just found instructions for how to do
that on SO. So now I have make install ran, so how can I construct binaries
for various platforms from this? Can you even compile to a windows binary
from Linux?

Re: Piping contents of SVG directly to stdout
So I have my Ubuntu VM setup and per the link from Jean, I've ran autogen, but when I try to do "../configure --enable-cairo-backend", it says "configure: error: no acceptable C compiler found in $PATH". How should I fix this?

Re: Piping contents of SVG directly to stdout
Sorry. I think this should reply to all now. As for the example I sent,
that's the barebones type. The ones I need to generate dynamically will
have random notes and key signatures and what not. I'll try WSL though. I
didn't even think of using that. I'll give it a go and respond here if
something comes up.

Piping contents of SVG directly to stdout
Hello, I'm using lilypond to programmatically generate sheet music. I already have a system in place to crop the SVGs, but now I need to load them in my software. I could use the default behavior of letting lilypond write to some file, and then reading it, but file I/O tends to be pretty expensive, especially when you're doing it in bulk like I am, so I'd like to avoid that. My question is this: Is there a way to get lilypond to write the output to stdout to save on performance, or do I need to use a file as a middleman? For reference, my current command is: "lilypond --svg --loglevel=none file.ly" Thanks, Felix
