python to lua code example

Example: python to lua converter

I wound up figuring it out on my own after some hardcore trial and error. The function rgb2short should have been:

 function rgb2short(rgb)
     -- Find closest xterm-256 approximation to the given RGB value
     _create_dicts()
     rgb = _strip_hash(rgb)
     local res = ""
     local equiv = ""

     local incs = {"0x00", "0x5f", "0x87", "0xaf", "0xd7", "0xff"}

     for part in string.gmatch(rgb, "(..)") do
         part = tonumber(part, 16)
         i = 1
         while i < #incs-1 do
             s, b = tonumber(incs[i]), tonumber(incs[i+1])
             if s <= part and part <= b then
                 s1 = math.abs(s - part)
                 b1 = math.abs(b - part)
                 --break
             --end

                 if s1 < b1 then
                     closest = s
                 else
                     closest = b
                 end
                 res = res .. string.format("%02x", closest)
                 break
             end
             i = i + 1
         end
     end


     equiv = rgb2short_dict[res]

     return equiv, res
 end
