Does Quarto (re)install its own version of Pandoc?

[mgiugliano]

I wonder whether I can safely play and explore Quarto, without affecting my existing Pandoc installation and experimenting.

I am under macOs and I install everything with Homebrew (cask). Should I worry for conflicts, for multiple versions, etc.?

Quarto bundles its own version of pandoc, which shouldn't conflict with anything in your filesystem.

Also, if you want to access the version of pandoc bundled with Quarto you can do so with:

quarto pandoc <any-pandoc-args>

For example:

quarto pandoc --version
quarto pandoc --list-output-formats
quarto pandoc foo.md --to gfm --citeproc

Thank you both!

While the following might NOT actually qualify as a "conflict", but I just posted on the RStudio community forums my experience with Pandoc failures after upgrading RStudio IDE: https://community.rstudio.com/t/rstudio-update-causes-r-command-line-failure-to-find-pandoc-which-has-been-moved-to-quarto-folder/150846

It's not a "conflict", and I'm not sure how command line executed R using rmarkdown originally knew where to find Pandoc, but it couldn't find it any more after the change in location.

Packages (including rmarkdown) generally check the RSTUDIO_PANDOC environment variable to determine the location of Pandoc bundled with RStudio, so a change of location shouldn't cause a problem (assuming this variable is being properly checked). Not sure what is going on in the scenario you are describing.
