function string:split(delimiter) | |
local result = {} | |
local from = 1 | |
local delim_from, delim_to = string.find(self, delimiter, from, true) | |
while delim_from do | |
if (delim_from ~= 1) then | |
table.insert(result, string.sub(self, from, delim_from-1)) | |
end | |
from = delim_to + 1 | |
delim_from, delim_to = string.find(self, delimiter, from, true) | |
end | |
if (from <= #self) then table.insert(result, string.sub(self, from)) end | |
return result | |

local example = '&$var.example.&$var'
example:split('&$var')
This will return '.example.' instead of ' ', '.example.', ' ' as before.
Alternatively, can be change to return '', '.example.', '' if pleased.
