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*", "")
This does not seem to work. How can I remove all of the spaces?
It works, you just have to assign the actual result/return value. Use one of the following variations:
I use
%s+as there’s no point in replacing an empty match (i.e. there’s no space). This just doesn’t make any sense, so I look for at least one space character (using the+quantifier).
