How to check if there are two concatenated methods with regex?
What is the best way to check, if there are any lines with two methods concatenated? In my case between .where(*) and .first, .last, .single
For example,
I want to get: foo.where(smth).first()
But not: foo.where(smth).bar().first()
So if there two concatenated methods (.where with .first or .last or .single), I want get this line.
I've tried to make regex for it: .where(.*?).(first|last|single)
https://regex101.com/r/3a7SpE/1
But, as I understood, back tracking makes foo.where(smth).bar().first() also "correct".
What should I change to make this works, please?

Try.where([^()]*?).(?:first|last|single), but if the text inside parentheses can contain(or), the task becomes much harder. Do you need to match specific grammar?

Thanks, it got better. But unfortunately, another method is possible in .where(), and text inside parentheses could contain other parentheses..

Do you think matching any amount of nested paired parentheses will work for you? What is the programming language?
– Wiktor Stribiżew

I guess yes. As test case I use: a.where(x -> x.getName() != "something").first() Programming language is Java.

Ok, so, regex is not an option.
