 Posted: Sun Sep 10, 2017 7:33 pm Post subject: Copy text from terminal outputs ^C |
 |
|
Hallo!
I am new to gentoo and have started to set up my installation last August.
From the days when I started to work with linux in the early 2000s I have used Ctrl+Shift+C in terminals for copying text. At least I can't remember that I have ever had trouble with Ctrl+Shift+C / Ctrl+Shift+V for Copy and Paste.
Now with my first gentoo I am annoyed by the strange behaviour in lxterminal that outputs ^C when copying text. Regrettably I did not succeed with my searches in the net to find a solution.
My DE is lxde.
Could you please help.
Karl

| I use several DE's (not LXDE howver). I never had trouble highlighting text with the mouse (left mouse down then drag the mouse), then right clicking the mouse to get the menu which should include "copy" and also "paste". |

Thanks for your reply. But that doesn't answer my question. It is not my mouse that is making trouble. It is entering Ctrl+Shift+C in the keyboard!
I avoid using the mouse as much as I can. Sorry, that I missed to mention this antiquated habit.

| Whether Ctrl+Shift+C is handled specially depends on the terminal and on its configuration. All terminals I remember using pass it through as a regular ^C. On the system that treated that as copy, was that also LXDE with lxterminal? If not, what terminal did you use before? |

Yes, as I mentioned in my first post it was lxterminal. By the way, I just checked in SystemRescueCd where Xfce Terminal Emulator is used. Ctrl+Shift+C goes without ^C. The same in Xterm.
I have found a good explanation on
https://wiki.archlinux.org/index.php/Copying_text_from_a_terminal
But I couldn't figure out how to change this behaviour. |

| Not sure if you still couldn't copy: With most X11 virtual terminals, selecting the text will put it in the non-desktop clipboard. Use middle mouse to paste. There is generally a menu for keyboard chords in a terminal emulator (unless it's something like urxvt). Have you found it? |

I am sorry for having caused misunderstandings.
The issue is not that it’s not possible to copy and paste. The issue is that entering Ctrl+Shift+C in the keyboard is accompanied with the output of the string “^C” to the terminal + opening a newline.
That’s inconvenient for instance when one wants to compose a command by selecting snippets from other elements already appearing in the terminal and pasting them to the command line. |

Afraid not. lxterminal is rather minimalistic and does not contain any shortcut key configurability.

You could try adding the shortcuts to ~/.Xresources then logout and login again for them to take effect.
| Code: | $ cat ~/.Xresources
XTerm*vt100*translations: #override \n \
Shift Ctrl <KeyPress>C: copy-selection(CLIPBOARD) \n \
Shift Ctrl <KeyPress>V: insert-selection(CLIPBOARD) \n |
That stops lxterminal issuing ^C in my case, and does indeed copy the highlighted text.

Regrettably this doesn't help either.
And my guess is that this behaviour depends on the compilation of some of the components involved in lxterminal. This seems most probable to me because I didn't need a Xresources-file before when I used other Distros.
But where to dig further? |

What key bindings do you have in in your ~/.config/openbox/rc.xml file?
EDIT: Something along the following lines in the keyboard section of rc.xml might do it:
| Code: | <keyboard>
...
<!-- Ctrl+Shift+c Copy X selection to clipboard -->
<keybind key="C-S-c">
<action name="Execute">
<command>sh -c 'xsel -o | xsel --clipboard'</command>
</action>
</keybind>
...
</keyboard> |

Thanks for your message (Mo Sep 11, 2017 7:00 pm).
With the keybind you recommended it finally works!
EDIT: Reporting a success was to early! The behaviour now changed so that Ctrl+Shift+V does not paste any more. The same in gvim. Copying with Ctrl+Shift+C can only be used together with Shift+Ins. |

Try adding a key binding for pasting, then:
| Code: | <keyboard>
...
<!-- Ctrl+Shift+v Paste clipboard contents -->
<keybind key="C-S-v">
<action name="Execute">
<command>sh -c 'xsel -o | xvkbd -xsendevent -file -'</command>
</action>
</keybind>
...
</keyboard> |
If not already installed, you'll need to install xvkbd as well as xsel.
EDIT: Added missing '-o' option to xsel command.
EDIT2: Tested in LXDE/Openbox in a VirtualBox VM and it works for me.

Fitzcarraldo, thank you once again. I have already noticed the thread of PQPGuy.
I have made a test with the key bindings you recommended and they work. But as I have noticed Ctrl+Shift+C / Ctrl+Shift+V is only useful within the terminal. To transfer some text from lxterminal to another program did not work. For instance to take text from lxterminal and paste it into the address line of pcmanfm or to gvim did not work.
The version was lxterminal 0.1.11. Being frustrated I have downloaded the version 0.3.0 from lxde and compiled by myself. Now everything works fine. Sorry for my impatience. |

| OP: so the ebuilds linked in lxde-base/lxterminal-0.3.0 version bump (and shown in lxde-base/lxterminal: Bump to 0.3.0) are sufficient for the new version? Based on some of the comments in the bug, it was a bit unclear if the earlier attempts work, and the automated test rejected charles17's work (though the output looks like a spurious rejection due to bad luck/timing), which may discourage the maintainer from pulling it promptly. If the ebuild worked for you, that might encourage the maintainers to merge it. |

Hu,
I did not use an ebuild, I was not even aware that some lxde-base/lxterminal-0.3.0 version existed! In my /usr/portage I have found only 0.2.0-r1.ebuild and 0.1.11.ebuild. As mentioned at the beginning I am new to gentoo.
What I did was to download the source code from lxde.org and compiled and installed lxterminal by myself. |

| To what path did you install it? Installing programs system-wide outside control of the package manager is discouraged because Portage will not consider the requirements of those programs when maintaining the system. Installing under your home directory is fine, if you do not mind managing the dependencies by hand. In general, using an ebuild (from a reputable overlay, if necessary) is preferred so that Portage has a complete view of what is installed on the system. |

I use these two aliases to modify and read the clipboard from my terminal.
| Code: | getclip='xclip -selection clipboard -o'
setclip='xclip -selection c' |

Hu,
you are right, of course. It was brute and dirty what I did.
And I am aware that now - from portage point of view - lxterminal doesn't exist at all on my installation. (I have unmerged lxterminal.0.1.11 in advance and have now /usr/local/bin/lxterminal, i.e. system-wide.)
But reading the line "Fixed issue with 'ctrl-shift-c' accel sending 'ctrl-c' to terminal" in the NEWS document of lxterminal-0.3.0.tar.xz was exactly what I was looking for. So, why should I reinvent the wheel and fiddle with workarounds when the work was already done by the developers? On the other hand, the situation with lxterminal seems somewhat exceptional to me as nothing depends from lxterminal. So, I have thought that this shouldn't be a big issue and I can resolve the problem sometime in the future.
Thank you for your advice. |
