Adding option to pandoc call from RStudio

+1
−0

If ones uses RStudio to convert a rmarkdown file to pdf, RStudio will call pandoc with arguments like this:

/opt/homebrew/bin/pandoc +RTS -K512m -RTS Untitled.knit.md --to beamer --from markdown+autolink_bare_uris+tex_math_single_backslash --output Untitled.tex --lua-filter /Library/Frameworks/R.framework/Versions/4.1-arm64/Resources/library/rmarkdown/rmarkdown/lua/pagebreak.lua --lua-filter /Library/Frameworks/R.framework/Versions/4.1-arm64/Resources/library/rmarkdown/rmarkdown/lua/latex-div.lua --highlight-style tango --pdf-engine pdflatex --embed-resources --standalone

Is there an environment variable or setting which can be used to add the --verbose option to this call?

I'm aware that one can set pandoc arguments within the yaml header of a rmarkdown file, but I'm looking for a way to automatically invoke the verbose option for all files.


RStudio version: 2021.09.0+351

Does rstudio invoke pandoc using an absolute path? (2 comments)

Building slightly on Olin Lathrop's suggestion, does rstudio actually invoke pandoc using an absolute path? I'm thinking that if it doesn't, you could put a small script in some directory that occurs before /opt/homebrew/bin in your $PATH. On the other hand, if it does, consider from where it gets the full path. Maybe that can be configured? (It doesn't sound like you are trying to make a change that would break anything if it isn't applied on invocation.)

Canina‭ Nice idea! As far as I can tell Rstudio uses an absolute path, but it turns out this path can be customised in .Rprofile via Sys.setenv(RSTUDIO_PANDOC="/path/to/some/folder/"), so I could point it to a wrapper script which adds the verbose option to the call. If you would like to write an answer, I'd be happy to mark it as "Works for me"!
