Concatinate string literals using IntelliJ IDEA Structural Replace

Question

I am trying to search static concatenation of strings and combine them into single string using Structural Search Replace.

For instance I want to search replace "String1"+"String2"+"String3" and replace with "String1String2String3" .But it should not replace strings in comments.

public class Main {
    public static void main(String[] args) {
        String s =    "String1"+"String2"
                      +"String3";

        System.out.println(CONSTANT);
    }

//    private static final String CONSTANT ="String1"
// +"String2"+"String3"
}

If I search for

"$String1$"

It results in 1 occurrences for above string However

"$String1$"+"$String2$"

Doesn't match above string

How does Structural Search Replace work? How to refer to variables found in Search string in Replace String

Good question, but it seems to me that it is unneeded, as java compiler concatinates such strings by itself. You can compile your example and look into the decompiled class file. — Vic, Nov 16 '14 at 08:38
Thanks I am aware of that, this Question is more around Structural Search Replace and understanding how it works, as there is not much documentation around this. — Prashant Bhate, Nov 17 '14 at 15:42

It looks like Structural Search does not currently support your use case exactly. You can match your string using the query:

"$String1$"+"$String2$"+"$String3$"

and replace with:

"$String1$$String2$$String3$"

But this will only find string concatenations of three string literals. You may want to file a bug report at http://youtrack.jetbrains.com
