QUESTION

How to have IntelliJ formatter wrap code after the . separator?

Asked 2022-Mar-31 at 15:19

Is it possible to configure the IntelliJ java formatter to wrap lines after the . separator instead of before it?

Example

String s = new StringBuilder("User{").
    append("Name=").append(name).append(",")
    append("Email=").append(email).append(",")
    append("Phone=").append(phone).
    append("}").toString();

Yes this formatting is odd, but I have inherited this formatting along with the CheckStyle NoWhitespaceBeforeCheck on a DOT which enforces it.

We do use Eclipse formatting so if there is an option in there, that would be useful.

No, that's not possible. There's a feature request for that, you can follow it here https://youtrack.jetbrains.com/issue/IDEA-123881
