How to swap words in a parentheses "()" using regex in Notepad++

Question

How can I replace the words like:

something(name_one,name_two).

into

something(name_two,name_one).

I've tried something like ^(.+),(.+)$ and replace with \2,\1, but not success and it turns out to be like this:

name_two).,something(name_one

Answer 1

You have to exclude from the capturing groups what you don't want to be swapped.

Replace

something\((.+),(.+)\)

with

something(\2,\1)

(see demo)

Or

Replace

\((.+),(.+)\)

with

(\2,\1)

(see demo)

Please notice that \( and \) are escaped parentheses, so they will match literally an open parenthesis and a closed one.
