Description Christoph Burgmer 2009-01-20 06:57:40 UTC 
Version:            (using KDE 4.1.3)
OS:                Linux
Installed from:    Debian testing/unstable Packages

When copy and pasting strings with Konsole being the source, tabs "\t" (and from my experience probably other whitespace characters) occuring at the end of a line in Konsole get swallowed.


Testcase

In the following example I print an array of numbers separated by tabs three times, once at line size 80, then 82 and 84. See what happens when I paste the output into the bug report:

$ python

>>> print '\t'.join(b)
14      12      11      8       8       7       7       5       2       3      22       1       2       1       1       1       0       0       4
>>> print '\t'.join(b)

Comment 1 Christoph Burgmer 2009-03-13 07:33:31 UTC 
Still in KDE 4.2.1

I would appreciate confirmation from you developers. Thanks.

For the testcase above, I forgot the line:
>>> b = [u'14', u'12', u'11', u'8', u'8', u'7', u'7', u'5', u'2', u'3', u'2', u'2', u'1', u'2', u'1', u'1', u'1', u'0', u'0', u'4']
to initialize b first.

Can you try the latest 4.2.x?

Here's what I get on trunk

>>> print '\t'.join(b)
14      12      11      8       8       7       7       5       2       3      22       1       2       1       1       1       0       0       4
>>> print '\t'.join(b)
14      12      11      8       8       7       7       5       2       3      22       1       2       1       1       1       0       0       4
>>> print '\t'.join(b)
14      12      11      8       8       7       7       5       2       3      22       1       2       1       1       1       0       0       4

So the 2nd line shouldn't have '22' ?
Comment 3 Christoph Burgmer 2009-07-05 20:12:17 UTC 
KDE 4.2.4, Konsole 2.2.3

Correct, 2nd line should not have a 22.

I think you did the command three times and only then resized the window, as I can still reproduce my original findings. You should do Command, Resize, Command, Resize, Command.
Comment 4 Christoph Burgmer 2010-03-26 15:20:49 UTC 
Still present in 4.3.4

Created attachment 64483 [details]
results in various terminal emulators

well, I can reproduce the reported problem with konsole-2.7.2 . However, the reported problem also happens with almost the same result in every terminal emulator I have tested. So I am not sure whether this is a bug or an expected (wrong) behavior.

The attachment is the summary of the results in xterm/konsole/vte/rxvt-unicode/mlterm/putty .
Comment 6 Jekyll Wu 2012-02-25 17:51:39 UTC 
Close it as WONTFIX according to my observation in comment #5.
