Replace string inside curvy brackets - visual-studio-code

Question

I would need to replace the strings contained within the curved brackets with the same strings but with an initial prefix and curly brackets \fill{(test_string)}. Is this possible?
Example:
Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam
nonummy nibh euismod tincidunt ut laoreet dolore.
(first_string)
Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy
nibh euismod tincidunt ut laoreet dolore.
(second_string)
Transform in:
Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam
nonummy nibh euismod tincidunt ut laoreet dolore.
\fill{(first_string)}
Lorem ipsum dolor sit amet, consectetuer
adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore.
\fill{(second_string)}

As suggested, you could use a regex search and replace. A simple example of this can be found here. In your case, this should work:
The regular expression \(([^\)]+)\) does the following (as taken from this site - you'll need to paste the regex into the site to see the explanation):
\( matches the character literally (case sensitive)
1st Capturing Group ([^\)]+)
Match a single character not present in the list below [^\)]
+ matches the previous token between one and unlimited times, as many times as possible, giving back as needed (greedy)
\) matches the character ) literally (case sensitive)
\) matches the character ) literally (case sensitive)
In Visual Studio Code, if you enable regex search by clicking the .* icon in the search bar, you can put this regular expression in. Then, in the replace section, you can put \fill{($1)} where the $1 is the 1st Capturing Group mentioned previously (the first_string, second_string, etc. part found by the regular expression).
There are a lot of Regex posts here on Stackoverflow you may want to read. One notable one is Greedy versus Lazy.
