How to remove spaces from a string in Lua?

Question

I want to remove all spaces from a string in Lua. This is what I have tried:

string.gsub(str, \"\", \"\")
string.gsub(str, \"% \", \"\")
string.gsub(str, \"%s*\"         


        

Answer 1

If anyone is looking to remove all spaces in a bunch of strings, and remove spaces in the middle of the string, this this works for me:

function noSpace(str)

  local normalisedString = string.gsub(str, "%s+", "")

  return normalisedString

end

test = "te st"

print(noSpace(test))

Might be that there is an easier way though, I'm no expert!
