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

Answer 1

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
