'VLC-LUA: using net.stat

I am trying to write a function that finds the first .waste dir in one of the parent dirs (e.g. .. ../.. ../../..).

For this I need to see if the dir exists. For that I would imagine net.stat would be useful.

But this fails:

vlc.net.stat("/")

with:

lua warning: Error while running script /home/tange/.local/share/vlc/lua/extensions/WasteBasket.lua, function activate(): /home/tange/.local/share/vlc/lua/extensions/WasteBasket.lua:42: attempt to index field 'net' (a nil value)

From the error it almost looks as if vlc.net does not contain vlc.net.stat - but net.stat is listed on: https://www.videolan.org/developers/vlc/share/lua/README.txt

An example using net.stat for VLC-LUA will be very appreciated.

I ended up using os.execute("cd " .. dir) to see if a dir exists.

It works, but I regard it as a hack.

function directory_exists(dir)
  -- Simple checker if dir exists
  -- shell quote the dirname
  dir, _ = dir:gsub("([\002-\009\011-\026\\#?`(){}%[%]^*<>=~|; \"!$&'\130-\255])", "\\%1")
  dir, _ = dir:gsub("\n", "'\n'")
  return os.execute("cd " .. dir)
end
