Hi there!
I can’t find out how to remove linebreaks using string.gsub.
Example, my string is:
"Hello
World"
I’d like to have “Hello World”.
I’ve tried this:
local str = [string here withouth the brackets]
str = string.gsub(str,"\n"," ")
print(str)
That didn’t work. (I get the string by requesting it from the web, and I’m sure it’s correct.)
Thanks in advance, and kind regards,
Jonas
Your solution works on your example, but my guess is that \n isn’t the only character you want to replace with spaces. Try str = str:gsub("[\n\r]", " ") to also find carriage return characters.
Hmm, that removed the whole string. 
I’m debugging, as it’s most likely my fault. I’ll keep you posted!
Awesome, that did the trick! What about tabs? Is it just the tab inside quotes, or a special code too?
Tab is \t, but if you just want to match all whitespace then you can use str:gsub("%s+", " ")
Thanks! I used \t because the other one also erased all spaces.
