Urgh. I love inconsistencies. :-(
Everything takes a screen number, but viewidx() wants a screen object.
New try:
function view_non_empty(step, s)
local s = s or 1
local scr = screen[s]
-- The following makes sure we don't go into an endless loop
-- if no clients are visible. I guess that case could be handled better,
-- but meh
local num_tags = #scr:tags()
for i=1, num_tags do
awful.tag.viewidx(step, scr)
if #awful.client.visible(s) == 0 then
return
end
end
end
(I also replaced awful.tag.visible with awful.client.visible)
