[book] Text of PARTS.qmd are missing in epub

[produnis]

Hi there,
my book follows this structure:

  chapters:
    - index.qmd
    - part: "R und RStudio"
      chapters:
        - installation.qmd
    - part: grundelgende-r-befehle.qmd
      chapters:
        - rechnen-mit-r.qmd

while everything works fine with PDF or HTML output,
all text in qmd-files of a "part" (e.g. part "grundelgende-r-befehle.qmd") are missing in output format "epub".

Is there a way to render to epub with these part.qmd-files?

I believe "parts" are not supported in books in general. We should probably do a better job at validating the yaml, but it's my understanding that book chapters need to be a flat structure, as shown here.

thx for pointing this out... however, in output HTML it is working... ;)

We do support parts for HTML / PDF output, but Word and epub don't really have the concepts of 'parts', so we don't support this for those output types. It would be good to update the docs to note this in the section on parts, which I will do!
