[SOLVED] How can I 'match whole word only'?
Most audios that have been amplified have 'loud' in the title. I have a boombox and I want to prevent these audios being played. I have made it so that if it finds 'loud' in the title or description then it gets refused. The ROBLOX studio search (CTRL+F) lets you search for a whole word only so it can't be included in a word, as 'loud' is in 'cloud'. I can't think of a way to do this, my current code searches for the word, but not just the word, so these are the results when searching for loud:
1 | 'cloud' --> true |
2 | 'cloud.' --> true |
3 | 'louder' --> true |
4 | 'louder.' --> true |
5 | 'loud' --> true |
6 | 'loud.' --> true |
But these are the results I want:
1 | 'cloud' --> false |
2 | 'cloud.' --> false |
3 | 'louder' --> false |
4 | 'louder.' --> false |
5 | 'loud' --> true |
6 | 'loud.' --> true |
I can't work out a method for achieving this, I hope you can help!

You should 1st look at Character Classes as you will need to understand how string patterns work.
The main problem is knowing when a new word has started which is why cloud would match.
The pattern %f[%l]loud%f[%L]%.? this will look for the whole word loud in lower case %l I have also added '%.?% which will look for 0 or one match of the literal '.'
My testing:-
01 | local test = { |
02 | 'loud', 'loud.', 'Loud', 'Loud.', |
03 | ' loud', ' loud.', ' Loud', ' Loud.', |
04 | ' loud ', ' loud. ', ' Loud ', ' Loud. ', |
05 | 'cloud', 'a loud', 'very' |
06 | } |
07 |
08 | local pattern = '%f[%l]loud%f[%L]%.?' |
09 |
10 | for i, str in pairs(test) do |
11 | local match = str:match(pattern) |
12 | if match then |
13 | print('String found index', i,'String ', str, 'Res', match) |
14 | else |
15 | print('Did not find', str) |
16 | end |
17 | end |
I hope this helps.
Hey, this is gonna be a short answer because, I literally have like 1 minute but, here are the scripts that I managed to come up with: If you don't understand anything please post it in the comment below.
01 | -- Won't print anything |
02 | local matching = "loud" |
03 | local name = "cloud" |
04 |
05 | for w in string.gmatch(name, matching) do |
06 | if #w == #name then |
07 | print(w) |
08 | end |
09 | end |
10 |
11 | -- Will print "loud" |
12 | local matching = "loud" |
13 | local name = "loud" |
14 |
15 | for w in string.gmatch(name, matching) do |
16 | if #w == #name then |
17 | print(w) |
18 | end |
19 | end |
Thank you for your time and I am sorry this is a really messy answer but, it should be helpful. Don't forget if you don't understand anything, comment below.
