I believe that tricks of the trade includes a similar solution to this one:


s = "sdf;sd;a;;b;;c"

for p in s:gsub(";;", "\0"):gmatch("([^\0]+)") do
   print(p)
end

I'm not aware of a way for Lua's pattern matching system to do what
you're asking for in one step (although, like you, I wouldn't be
surprised to find a simple answer from someone else.)

LPEG can do this in one step, but this might be better for such a
straightforward case.
