Re: [jdt-core-dev] Strange formatting when using JDT core DOM infrastruc

Thanks Olivier!

Changing my code to:

        declaration.modifiers().add(0, annotation);

indeed moved the annotation before the public declaration.

Now for your second advise (to format the code after I get it from the document). I tried to follow this great forum discussion:

http://www.eclipse.org/forums/index.php/m/829341/

However, if I create my TextEdit this way:

        CodeFormatter formatter = ToolFactory.createCodeFormatter(null);

        TextEdit edit = formatter.format(0, document.get(), 0, document.get().length(), 0, null);

        edit.apply(document);

Then I lose all the modifications that I did in the lines before and get the initial class (now formatted):

public class JavaClass {

}

I tried to call unit.rewrite(document, null); before formatter.format, but without luck.

Could someone tell me how do you format my document?

Thanks again!

Ivan

P.S. I saw also that there is this package org.eclipse.jface.text.formatter, which has some ContentFormatter classes. While I am using org.eclipse.jdt.core.formatter.CodeFormatter. What is the correct way?

Hi,

You can add the annotation in the first position inside the modifiers. You can format the code at the end once you get the source from the document.

Hi folks!

I'm working on the JBoss Forge tool (https://docs.jboss.org/author/display/FORGE/Home). For some of its features it uses JDT core tooling to generate or modify Java classes. For example, it may create JPA entities. However, the final format is quite weird:

package com.example.test;

import javax.persistence.Entity;public @Entity class Employee {}

I would expect something like that:

package com.example.test;

import javax.persistence.Entity;

@Entity
public class Employee {}

You noticed how in the generated input the import, the annotation and the class declaration are on a single line? And @Entity is placed between the public and class words?

I have attached here a sample class, which demonstrates how we use the JDT parser API. Could you please tell me what I am doing wrong? And is it possible to have more beautiful formatting?

Thanks and regards,
