How do I detect only spaces in strings?
I was wondering what should I do to detect if a string only contains spaces only like for example if a TextBox Text would be like:
TextBox.Text = " "
Also, if someone does like:
TextBox.Text = "Hi "
It would be ok since the result isn't only blank.
Not sure if string.gmatch(TextBox.Text,'+%s-%w-%p') would be right but I would need advice on how this would be executed, thanks!

What I did to counter this was set up a for loop, then loop through the string and see if it isn't all strings. For example:
local AllIsSpaces = true
local String = ' '
for i = 1, #String do
if String:sub(i, i) ~= ' ' then
AllIsSpaces = false
end
end
if AllIsSpaces then
print('It\'s all just flippin spaces! D:<<')
else
print('Accepted! ^^')
end
There's probably better ways out there, but this's the solution I've come up with thus far. :P If you have any questions, please ask away! ^^
I hope this helped! :D
if string.match("here's a string with non-whitespace characters", "%S") then
-- code
end
The %s character class matches all whitespace characters, and the %S character class matches the complement (all non-whitespace characters).
