Windows Vista and REPL caret disappearing

I have exactly the same problem! I experience it on both WinXP and
Win7 x64. It seems all versions of windows are affected. Very annoying
and almost rendering the REPL useless.

Win7 x64. It seems all versions of windows are affected. Very annoying
and almost rendering the REPL useless.

I see it too, and it's annoying, but nowhere near rendering REPL useless.

Ok, maybe I was exaggerating, but IMHO it is extremely annoying and
significantly hinders REPL usage.

I have the exact same problem with every console-based REPL I use on Windows, not just the Scala REPL.

So perhaps it is a library issue?
The builtin windows or native software is not affected - shell works ok,
edit works ok, psql interactive shell works ok, git console works
correctly, too.

Hmm, I've just found an open ticket for it #2547.

------------------

On Windows, scala interpreter does not show caret(or cursor) during
left/right arrow keys are pressed.

Suppose I typing like below.

scala> println("Helo scala"

Caret is end of line. When I try to go back few chars to correct "Helo"
to "Hello", scala interpreter does not showing caret, during left arrow
key pressed down.

I can't see where I am now during move around in line. I hope this to be
fixed.

Environment:

-Windows XP SP3 -Scala 2.7.7 final (I tried with some build of 2.8,
but situation does not seems to fixed)

---------------------

Have anyone told the jline developers to fix this?

Ok, I have added an issue to the jline bugtracker:
3019805

http://sourceforge.net/tracker/?group_id=64033&atid=506056

I hope, they will fix it soon.

Everything works on Linux. This seems to be Windows-only problem.

Ha, ha. jline has been abandonware for a long time. Many people have
forked it in various directions, us included. Recently nutter from
jruby has made an effort to consolidate the various fixes which are
spread around town. I tried rolling that branch a few weeks ago but for
whatever reason it didn't work at all with scala trunk and that was the
extent of my interest.

http://sourceforge.net/mailarchive/message.php?msg_name=AANLkTildXcat29J...

Anyway, it's buggy, we know, and waiting around for someone to fix it
has not been the slam-dunk strategy I've have thought. Maybe it will
work out better for you than it has for me!

Well, I swear I've seen it with Python and Ruby repls under Windows XP.

Hi,

another strange problem. I've noticed the cursor disappears when I move it in scala console and sbt console.

FYI, I'm using Console2 on Windows 7 and am not having this issue:
http://sourceforge.net/projects/console/
Might be worth a shot.-Mike

It works for me too! It solves the problem completely and additionally
enables nicer fonts. Thank you very very very much. :)
