这个正则表达式做了什么？

Question

^.+\\(.*\\)

I am struggling to work this one out, any help would be greatly appreciated...

also is there a site that lets youu paste in a regular expression then spits out in plain text what it means?

Answer 1

Others have already described it's components, so I'll give you some examples - allthough I'm not sure what \\( and \\) stands for. It depends on your regexp-engine. If they match literal parenthesis, this regexp will match the following strings:

abc(def)
abcdef()

but won't match these:

abc
(abc)
abc(def)ghi
(abc)def

In case they match literal slashes and open/close a group, your regexp will match:

abc\def\
