function explode(input, separator) | |
if input:len() == 0 then return {} end | |
if input:len() == 1 then return { input } end | |
separator = type(separator) == "string" and separator:sub(1, 1) or tostring(separator) | |
local results = {} | |
local lastPos = 1 -- Note: in Lua, '1' is the start of everything, including strings | |
for i = 1, input:len() do -- or: for i = 1, string.len(input) do | |
if string.sub(input, i, i) == separator then -- or: if input:sub(i, i) == separator then | |
table.insert(results, string.sub(input, lastPos, i - 1)) | |
lastPos = i + 1 -- Not set to 'i' because that would be the comma itself | |
end | |
end | |
if string.len(input) ~= lastPos then | |
table.insert(results, string.sub(input, lastPos)) -- This is to get the very last argument | |
end | |
return results | |
end | |
for i, v in pairs( explode("hello,world,how,are,you") ) do | |
print(v) | |
