Lua string split for 5.2

Question

I'm having some trouble with what I believe is this commonly used string split function for 5.1:

utils = {
split = function(str, pat)
   local t = {}  -- NOTE: use {n = 0} in Lua-5.0
   local fpat = "(.-)" .. pat
   local last_end = 1
   local s, e, cap = str:find(fpat, 1)
   while s do
      if s ~= 1 or cap ~= "" then
     table.insert(t,cap)
      end
      last_end = e+1
      s, e, cap = str:find(fpat, last_end)
   end
   if last_end <= #str then
      cap = str:sub(last_end)
      table.insert(t, cap)
   end
   return t
end
}

I'm using Lua version 5.2 and I was wondering if anyone has or knows of a string split function for 5.2, or if they could confirm or deny if this code would experience problems running in 5.2? Here's a link to my original problem for reference.

Answer 1

There will be no issues with that split function, from my POV.

note comment will be added, because of old(5.0) table length syntax. http://www.lua.org/pil/19.1.html

There was nothing, that can cause an error in such split implementation( It's known utility function, and I used in in multiple 5.2 projects, never have any problem's)
