clipr does not work on Wayland

[she3o]

It seems that the package can't tell that I am on Wayland

You probably have xclip installed. clipr first looks for xclip, then checks for xsel, and if neither is available, it falls back to wl-clipboard.

X11_write_clip <- function(content, object_type, breaks, eos, return_new, ...) {
  if (has_xclip()) {
    con <- pipe("xclip -i -sel p -f | xclip -i -sel c", "w")
  } else if (has_xsel()) {
    con <- pipe("xsel --clipboard --input", "w")
  } else if (has_wl_copy()) {
    con <- pipe("wl-copy", "w")
  } else {
    notify_no_cb()
  }

  .dots <- list(...)

  write_nix(content, object_type, breaks, eos, return_new, con, .dots)
}

I'm on Wayland, same error and I do indeed have xclip installed. I could swear it used to work even with this setup. However, I now removed xclip from my system and generally rely instead on wl-clipboard. Clipr started working again!
