Description mindrones 2010-05-19 15:24:03 UTC
Version:            (using KDE 4.3.5)
OS:                Linux
Installed from:    Mandriva RPMs

As the description says.

The major problem is that when you press ctrl-C because you remember that you have to do something, if the cursor is not at the end of the line but in the middle of at the beginning, and you press it while writing 

$ cd my/tmp/f|older
             ^ representation of the cursor position

you get 

$ cd my/tmp/f^Colder

and so if you wanna copy it to repaste after you've done the extra step you have to delete the ^C

Very annoying, in kde 4.3.5 it's wasn't like that, pressing ctrl-C just did the interruption without printouts

Might be cause by settings in konsole/settings/edit current profile/input tab.

There, I have currently "default (xfree4)"

But, in there, there is no ctrl-C mentioned as control char to sbe sent to the shell

Regards
Luca

Did you upgrade any other software at the same time as KDE?

Hi, no, it waslike that at first Mandriva 2010.0 install. After that I did the upgrades from mandriva but it's still the same.

Sorry for the double post.

Forgot to say that it happens also when the cursor is at the end or at 
the beginning of the line, not just when it's in the middle.

Thanks.

Hi, some other small issues

1) shift-home gives an "H" (I'm quite sure this is not a bug but reporting anyway just in case)

2) ctrl-backspace doesnt delete words backward, this is done by alt-backspace. But, since ctrl-leftarrow moves the cursor 1 word backward I think it would be more consistent if erasing backward was ctrl-backspace, which is also done by many text-editors and open-office, hence one could have this habit (not sure if this has historical reason tho)

Many thanks, Luca

When you used the previous version of KDE / Konsole that did not exhibit the problem, were you running a different version of other software besides KDE?  If you used KDE that was part of Mandriva < 2010.0 then the answer is likely to be yes.

Does the problem occur in xterm or gnome-terminal?

You mean GNOME? If so, no. I pretty much hate working in GNOME.

If you mean if I had software using GTK libraries how this should have something to do with this bug? :)

These 2 apps aren't installed on my system.

I've forgot to say, ctrl-canc erase words, so again, seems more natural to have
- ctrl-canc:        erase a word forward
- ctrl-backspace:   erase a word backward (now it's alt-backspace)
- ctrl-right-arrow: move cursor a word forward
- ctrl-left-arrow:  move cursor a word backward

If needed, and if you consider this a bug I can file a separate bug report.

Thanks.

The ^C problem is not a Konsole bug.

It happens the same with xterm and is related to your shell.

Bash in Ubuntu Lucid prints "^C", but zsh does not.

IIRC this is configurable somehow, but my main point here is: not a Konsole bug.


First zsh, then bash: - this comes from xterm, but it's the same with Konsole.
% foobar
% bash
$ foo^Cr

I have asked a question regarding this at superusers:
http://superuser.com/questions/146815/prevent-c-from-being-printed-when-aborting-editing-current-prompt

I am closing this bug as invalid. Please report any remaining issues in a new bug.
However, from skimming them, they appear to be related to shell configuration, too.
You really want to verify if "xterm", "gnome-terminal" etc behave differently, before filing a bug against Konsole.

Indeed putting 

stty -ctlecho

in ~/.bashrc did it

Sometimes it's just hard to keep up with everysingle cofiguration thing :)

Many thanks, Luca
