Is it possible to add a breakable for cross referenced Code Block?

[joelvonrotz]

Description

Hello everyone

I'm in a bit of a pickle. After resolving #8519 , I'm trying to solve the next problem. The goal is to have a cross referenced, syntax highlighted code block which is multiple pages long. Right now, to have the syntax highlighting AND be cross referenced, the code block is put inside a cross referenced div. Now is it possible to adjust the codelisting float environment to correctly break up the code block?

What I like to have (with cross referencing)

I know this behavior is due to the usage of a float environment, but is there a possible workaround?

[mcanouil]

That's a LaTeX question.
You'll have to tinker LaTeX code directly. Use keep-tex: true and play with the LaTeX file.

I am not even sure it's possible in plain LaTeX with the current output.

[cscheid]

As far as I can tell, it's not. page-spanning environments in LaTeX are complicated (there's longtable for tables and that by itself introduces a ton of extra complications in the typesetting)

[joelvonrotz]

Ah okay, that makes sense. I've found a workaround for now. By creating an empty cross reference div, remove a bit of vertical spacing between the caption and the code block and add the caption into the div-information, I kind of get what I wanted!
