How to remove all whitespace " " from string?

  1. How could I remove all whitespace from my multiline string?

  2. I already tried string.gsub(str," “,”"), but it does not seem to work with multiline strings.

  3. I have tried string.gsub(str," “,”") which works for single line strings, but I need it for longer. Any alternative/modified solutions are welcome, thanks!

If you take a look at the string function documentation page, you’ll notice .gsub’s second argument is a string pattern instead of just a specific string. To pick up any “space or whitespace character”, you can use %s+

The end result would be: string.gsub(str, "%s+", "")
