Cleaning the docs/reference folder from the files that may be generated by the examples of the documentation

[choisy]

In this minimalist repexpkgdown R package, there is one function, hello(), and the example of its documentation creates a file on disk. A consequence of this is that, when using the pkgdown package to generate a website for the repexpkgdown package, the file created by the example of the hello()function is created in the docs/reference folder, which we would like to avoid. Is there a way to automatically avoid this?
Thanks for help.

You can prevent the example from running with \dontrun:

#' @examples
#' \dontrun{
#' write.csv(mtcars, "mtcars.csv")
#' }

Yes, we thought of that too, but \dontrun is not a satisfying solution for us as we would like the examples to be run when we look at the documentation of the functions. What we are doing now is that we have a wrapper around the pkgdown::build_site() function that cleans the docs/reference folder after the site is built. We were thinking that adding such a cleaning functionality directly to the pkgdown::build_site() function would be something you may consider.

You won't be able to get a package on CRAN if it writes to the working directory; I think that suggests this isn't pkgdown's problem to handle.

(Thanks for the minimal reprex package!!)

Ah? Thanks for the info about CRAN!
(and thanks for pkgdown too!)
