Can't enable cache on local board

[wklimowicz]

First off, thanks for your work on this package!

I'm in the same situation as #669, where I want to enable caching for a slow network drive. The two functions suggested in #669 create a board, and create a folder inside ~/.cache/pins/, but the cache doesn't populate with any files. I've created a reprex repo here with a GitHub action showing that no file get's created after pin_read. Am I misunderstanding when the caching is intended to happen?

Oh yes, you are definitely right. Adding a cache path to the board isn't the only thing that needs to happen. What I said here about this just working is definitely wrong. I'm not sure why I thought that. Apologies to both you and the original poster!

Instead, what we would need to do is to set up board_folder() to act more like board_url(), for example, the caching that is implemented in http_download() here:

pins-r/R/board_url.R

Line 326 in 58082a3

http_download <- function(url, path_dir, path_file, ...,

I'll mark this as a feature request once more and we can again collect feedback on it. Thanks for your understanding!
