The pkgdown and now blogdown packages have the super-nice copy to clipboard buttons for code blocks (see https://github.com/rstudio/bookdown/pull/776 and https://github.com/r-lib/pkgdown/pull/415 ). Is it possible to get something similar for standard Rmarkdown documents? Has anyone done this and has a MWE perhaps referencing appropriate .js and .css files?
Thanks for the reply @mattwarkentin. The klippy is OK but feels a bit hacky and bookdown is probably overkill (I also have a system for outputting questions in one HTML file and solutions in another HTML file, but all text in the same Rmd file that I don't think would work easily in bookdown).
What would be really nice is an option in the YAML to enable/disable copy to clipboard buttons (along the same lines as the code_folding option).
I ended up borrowing out the relevant js, css and html files from the pkgdown pull request and incorporated that into my RMarkdown website.
Unless I am misinterpreting, bookdown::html_document2() is essentially a drop-in replacement for rmarkdown::html_document() to get access to the additional bookdown features. I use pdf_document2() and html_document2() very often in place of their rmarkdown relatives, even when I am only creating single Rmd documents.
You can definitely define a new YAML parameter to toggle copy-to-clipboard if you are comfortable editing the template files.
I didn't know about the bookdown::html_document2, that's cool and might be useful in future. Unfortunately, it seems the copy to clipboard functionality is specific to bookdown::gitbook format, so doesn't come "for free" with bookdown::html_document2.
