Hi list,

I started using Lua 5.3 for some things and I noticed that the
function "splitlines" in my LUA_INIT file doesn't work in 5.3. Here
its definition (warning: I wrote these functions 15+ years ago!

  split = function (str, pat)
      local arr = {}
      string.gsub(str, pat or "([^%s]+)", function (word)
          table.insert(arr, word)
      return arr
  splitlines = function (bigstr)
      local arr = split(bigstr, "([^\n]*)\n?")
      return arr

It seems that the behavior of string.gsub changed from 5.2 to 5.3. In
5.1 and 5.2 the

  arr = split(bigstr, "([^\n]*)\n?")

would always generate an sequence with an empty string at its end, and
table.remove would delete it.

I remember ___veeeery___ vaguely a discussion here in the list about a
change in string.gsub that made it stop substituting the empty sting
at the end, but I'm not being able to find it now... anyone has a
pointer to it? I don't know how to fix my code in an elegant way to
make it work in 5.2 and 5.3 and I would like to take a look at the

  Thanks in advance,
