Commit f32ca0b causes markdowncv themes to break?

[monicathieu]

I updated vitae to 0.6.0 because I was excited to try Colton Baumler's new ccbaumler theme for the markdowncv format. However, my previously rendering CV (using the davewhipp theme) suddenly started to render to a "plain" R Markdown and the theming fails to apply! I haven't changed anything on my CV Rmd.

Also, the following pandoc warnings are now showing up on the Render tab:

[WARNING] Could not fetch resource media/../fonts/academicons.ttf
[WARNING] Could not fetch resource media/davewhippbootstrap-screen.css
[WARNING] Could not fetch resource media/davewhippbootstrap-print.css

This suggests pandoc is failing to find the theme CSS paths, but I sadly don't don't know enough about how vitae calls knitr and pandoc under the hood to know what exactly the issue is.

I have narrowed it down to something in commit f32ca0b, which definitely suggests it's a knitr-to-pandoc issue of some sort. The theme appears correctly when I reinstall vitae on the previous commit (no changes to the Rmd file or anything else).

Annoyingly, the previous commit has that duplication issue the offending commit fixes. I saw some comments in #254 suggesting the duplication was arising from a knitr update, but I checked through several package versions and I actually think it came from the xfun 0.44 update--maybe because xfun::write_utf8() now returns con, not NULL? I did confirm that the theme-less CV knitted after commit f32ca0b does not duplicate the CV contents.

Relevant version info:

R 4.3.1 pandoc 3.1.11 knitr 1.47 (but this issue also happens with 1.43) rmarkdown 2.25

Thanks for the thorough investigation @monicathieu! I'll look into f32ca0b01d6e3e93e0f21152268dd10a28c153ed again, especially with how we might be using xfun::write_utf8().

Hi! Thank you @mitchelloharawild for this super helpful package and @monicathieu for tracking down the error.

I get the same warnings with this setup in Emacs with ESS:
