Put ... at the end of a string if it gets too large

[ben434]

I'm really bad with manipulating strings and I was wondering if I could get some help with something. How would I see if a string is larger than 11 characters and if it is, go to 8 characters and replace the last three characters with "..."?

[lua]
local str = "This is a very large string!"

if str:len() > 11 then
str = str:sub(1, 8) .. "..."
end

print(str) -- This is ...
[/lua]
