How to get carriage return without line feed effect in Eclipse console?

Question

If I

System.out.print("something\r");

at console, I have cursor back at the beginning of line, and finally after

System.out.print("something\r");
System.out.print(" any\r");

I have

 anything

typed.

But at Eclipse console I get

something
 anything

as if it treated \r as CR/LF.

How can I setup this?

Seems like an unresolved bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=76936 — , Feb 09 '13 at 23:02
While I can understand the use of this, I ask why you need it to work in Eclipse. It might be inconvenient, but at some point I would imagine that you will just have to test it in a console window, presumably its final execution place anyway. Eclipse is capable of running external programs for testing - I have to do it all the time since my program runs via .bat file. (Sorry I can't be of more help.:/ ) — Tustin2121, Feb 12 '13 at 17:06

As Nishant already pointed out in the comments, you've found a bug here.

This bug initially was reported in 2004 (>9 years ago!?!!) and this bug seems not to be fixed very soon (or ever). I tested it on several Eclipse version, even on Eclipse Juno SR2, and the bug is still there.

Does not work in Eclipse Neon Release (4.6.0) (Build id: 20160613-1800) – TuringTux Aug 09 '16 at 16:15
As of Eclipse 2020-03, the bug is *still* present. I guess some bugs are literal cockroaches! – ViceroyFaust May 12 '20 at 13:26
The bug is fixed now. See another answer. – Nathan Apr 19 '21 at 15:46

The bug is fixed by now (Eclipse 2020-03). Just go to

Window ➺ Preferences ➺ Run/Debug ➺ Console

and make sure that both checkboxes

Interpret ASCII control characters

and

Interpret Carriage Return (\r) as control character

are enabled.

        System.out.print(" any\r");
    }
}

Output

Move the mouse pointer into the console area, click on the right mouse button, a popup menu opens. Click on "Preferences..." item. Check "Interpret Carriage Return (\r) as control character" box. Click on "Apply and Close" button.
