XTend code generation and comments [message #1750734]

I noticed that the XTend infrastructure does not copy all comments over to the generated java file. Comments of the form "/*...*/" are copied but not comments of the form "//...".

Can I turn it on?
Is it implemented at all?

No you can't
The copying is done manually in the xtend impl

Actually comments are not always copied.

For example the xtend code below:

package flax.sandbox

/* comment 1 */
class Test {
    /* comment 2 */
    def void doSomething(String /* comment3 */ myParameter) {
        /* comment 4*/
    }
}

is transformed into:

package flax.sandbox;

/**
 * comment 1
 */
@SuppressWarnings("all")
public class Test {
  /**
   * comment 2
   */
  public void doSomething(final String myParameter) {
  }
}

This would be handy for IDE that parses stuff from comments (i.e IntelliJ IDEA todo feature).

Is that worth a feature request?

yes but xtext handles this (TODO/TASK Markers) stuff on the source base, not on the generated java base.
i dont know what is implemented in the xtext idea code base (there is no maintainer on it right now)

Apparenty nothing has been implemented yet with regards to TODO.

I am seriously considering contributing to the idea code base because there are many issues that need to get solved.

Who should I contact for that?

Hi. Additionally another question related to below code.

/* comment 1 */
class Test {
/* comment 2 */
def void doSomething(String /* comment3 */ myParameter) {
/* comment 4*/
}
}

Can we now convert all the block comments above from xtend to java or still comment 1 and comment 2 only converted yet ? Thanks in advance.
