string.split()

thinkrichroy

I think a string.split() function would be a nice edition to LuaRT. I've been working on a project for a while now, and I realized a string.split() function would be helpful for the project, and so save some time for future projects.

It would basically go like this:
local x = string.split("Hello world!", " ") Output: {"Hello", "world!"}

Hi thinkrichroy,

You can achieve this with the string.gmatch() function like this :

function split (str, sep)
        local  sep = sep or "%s"
        local result = { }
        for word in str:gmatch("(%w+)"..sep.."?") do
                table.insert(result, word)
        end
        return result
end

But I agree that a split function will be better and easier for newcomers. I will see if I can include it in LuaRT 1.8.0

PS : You can use string.gumatch() to respect UTF8 encoding

You can rename this function to "string.split()" and put it in a separate module like "stringextension". Load the module with "require("stringextension")". Then you can use it in the same way as the other string functions:

request("stringextension")

sting.split()

string.format()

It's done and will be available in LuaRT 1.8.0.
The function will support UTF8 strings splitting for both the string and the separator
