[FR] Syntax highlighting for odt_document (and bookdown::odt_document2)

[naikymen]

Hello!

As a LibreOffice user, I would like to have Knitted ODT documents with syntax-highlighted code chunks.

The word_document has this feature, but the odt_document output does not seem to have it.

Here is a reprex, I've knitted to DOCX and ODT, using rmakrdown and bookdown: reprex.zip

I'm not certain if this is a feature request or a bug.

It may be a bug, according to this Bookdown issue: https://github.com/rstudio/bookdown/issues/1394#issuecomment-1370134795

I'd like to stick to ODT, since using DOCX as an intermediary is nightmarish.

Is highlighting possible with odt_document or odt_document2? Are there workarounds?

Thanks!

Thanks for opening the new issue. It makes things clearer to track for us.

I checked with Pandoc as the highlighting feature comes from it, and it seems it does not support highlighting for ODT. From: https://pandoc.org/MANUAL.html#syntax-highlighting

Currently highlighting is supported only for HTML, EPUB, Docx, Ms, and LaTeX/PDF output.

This mean you can't use the standard highlighting mechanism provided by Pandoc, that most of the document rely on.

I don't think we have a solution for that... Not sure there is an external tool to highlight code for ODT document. I'll do some research.

For context on the Pandoc side

It seems it is still an open feature request:

• https://github.com/jgm/pandoc/issues/6710

with already only inline code highlighted

• https://github.com/jgm/pandoc/pull/6711

But code block is still not

• https://github.com/jgm/pandoc/pull/6717

It seems it needs to be reactivated and it is stale 🤔
