Bug 146175

Description Juergen Kremp 2006-06-09 02:45:05 EDT

Hello, 

I reported this issue already two years ago when 3.0 was out (cannot find it now. Probably deleted). It was closed with comment "Post 3.1". Now with 3.2 I still have the same error.

Eclipse 3.x is unable to produce the same Code Formatter results as Eclipse 2.1.2, even though there is a "Eclipse 2.1" mode and although there are many tweak settings. This causes me to have thousands of code differences in my source-code-revision system to appear as soon as I format older code (created in 2.1.2) with the new version. 

I have created an artificial example that demonstrates my main problem. 

This is the code as produced and formatted by 2.1.2:

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
package demo.formatter;

public class FormatterDemo {

    public void fooBar() {
        SomeOtherClass instanceOfOtherClass = new SomeOtherClass();

        /* The following statement demonstrates the formatter issue */
        SomeOtherClass.someMethodInInnerClass(
            instanceOfOtherClass.anotherMethod("Value of paramter 1"),
            instanceOfOtherClass.anotherMethod("Value of paramter 2"));

    }

    private static class SomeOtherClass {
        public static void someMethodInInnerClass(
            String param1,
            String param2) {
        }
        public String anotherMethod(String par) {
            return par;
        }
    }

}
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<

The critical part is the method invocation.

The best I can get out of Eclipse 3.x looks like this:

        /* The following statement demonstrates the formatter issue */
        SomeOtherClass.someMethodInInnerClass(instanceOfOtherClass
            .anotherMethod("Value of paramter 1"), instanceOfOtherClass
            .anotherMethod("Value of paramter 2"));

Besides that it creates many differences in source-code-revision system, it is also quite bad in visual style compared to the Eclipse 2.1.2 result. 

Kind regards,
Juergen Kremp
