Add function to copy vignette assets

[cynthiahqy]

litr::add_vignettes() only copies across the .Rmd file, but sometimes extra files are needed render the vignette -- e.g. .bib files (see units package), or image files. It would be great to have a utility function to copy these assets over.

For example something like:

add_vignette_assets <- function(files){
  fs::dir_create("vignettes")
  mapply(fs::file_copy, files, "vignettes")
}

That could be used as:

add_vignette_assets("../xmap-source-files/using-xmaps.bib", "vignettes")

Hi @cynthiahqy Thanks for this suggestion. Good point. It turns out I believe it would actually work for you to simply pass these additional files to litr::add_vignettes() like so:

add_vignettes(c("source-files/my_vignette.Rmd", "../xmap-source-files/using-xmaps.bib"))

Of course there would be no way for you to know that, so I'll update the name of the argument from rmd_files to vignette_files and update the documentation. But before I do so, would you mind confirming that this works for you? Thanks!

Hi @jacobbien, your suggestion works for me. I was just adding my own function into my litr doc and calling that, but reusing the existing one is even better. Cheers!

4518687 closes this issue. I decided to leave rmd_files as an argument for backward compatibility; however, I added a second argument for other files. Thanks @cynthiahqy !
