I have a string:

"whatever( here i com  ( asdfasDF ( ) ) ) go home"

I want to extract everything between the first "(" and last ")" which is:

" here i com  ( asdfasDF ( ) ) "

What is a good regular expression to extract that?

Update:

If my string contains newline chars the following works:

/\((([.|\s|\S])*)\)/

"whatever( here i com  ( asdfasDF ( ) ) ) go home"[/\((.*)\)/m, 1]

或者

"whatever( here i com  ( asdfasDF ( ) ) ) go home"[/(?<=\().*(?=\))/m]
