Re: Piping contents of SVG directly to stdout

[William]

Hope you won’t mind me hopping in here a little late because this sounds similar to a project that I was using lilypond for. My workaround is, as you know, spinning up a temporary directory for the output and all the extra eps files, run lilypond, read the output file into program memory, delete the temporary directory, then serve over http via the buffer in memory. 

So to answer your question, there is no way to pipe output from lilypond, but the IO overhead even if you’re using something like a cloud provider HDD is very minimal compared to how long lilypond takes to render the output (more time would be saved by utilizing virtual host caching for the results, for example)

Felix, I’m curious what you mean by cropping the file. Sounds to me like you are trying to just write a small snippet of music, maybe a few measures, and not have the output flooded by whitespace all around the size of an A4 paper? This is also similar to what I was using lilypond for and there are ways to do this without any external apps. 

Thanks,

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
