Lua's patterns aren't regular expressions and don't handle the
complexity of a regexp. Perhaps you want:
local last
for s in string.gfind(str, '([^\n]+)') do
last = s
end
The for loop will iterate over all substrings that match the pattern,
returning the last one. I changed the '*' in the pattern to a '+' to
avoid matching "\n" and returning and empty string.
Cheers!
