Php annotation regexp

Question

I need to parse php docComment annotations with regexp. Possible annotations: ``` /** * @Annotation() * @Annotation\Name("var1", "var2") * @Annotation(["var1", "var2"], "var3") * @Annotation\Filter\Name(["var1", "var2"], "var3", {"var4": "var5"}) */ ``` Basically `@Annotation(<json>)`. In php I decode it like this `json_decode('['.$json.']')` Now I use regexp `/@(\w+[\\\w+]*)$([^$]*)?\)/` but this is not always true. For example: ``` @Annotation("name()") ``` What regexp should I use? Is it possible to parse more than one annotation in the line? ``` /** * @a() @b("var1") * .... */ ``` UPDATE: How to write this in regexp: ``` # match annotation name # if brackets are empty # match ()[space|newline] # (else) if something is in brackets # match everything until: # ")[space|newline] # or })[space|newline] # or ])[space|newline] ``` UPDATE 2 What about this regexp `@((\w+)([\\\w+]*))(?:$\s*$|$(.*?["\}\]])(?:\s|$)*$)(?:\s|$)`. Can it be simplified? demo
