How do you add a space after every character in a string?

I don't really agree with Goulstem's solution. Forgive me for wanting better solutions.

local str = "This should have a space after every character"
local newstr = str:gsub('(.)','%1 ');

A character in this case is literally anything, meaning it will actually also insert spaces after spaces.

How does it work?

• (.) captures any character
• %1 stands for the character we captured
• puts a space after it.

To add a space after every character in a string, iterate through the string using gmatch. Use the string pattern %w to indicate an iteration on any found alphanumeric character. You can see a list of string patterns here.

While iterating, start creating a new string that consists of everything the old one had, but add a space in between.

local str = "Hello my name is Goulstem" --Your String
local newstr = "" --The new string

for i in str:gmatch("%w") do
    newstr = i.." " --Add a space
end
print(newstr);
