• Building CodeLite - Linux
In recent CodeLite versions on Linux, the terminal used to show any output from the debugged program is xterm. While this does work, it's not everyone's idea of a modern gui program; in particular by default it has no scrollbar, and standard keyboard shortcuts for Copy/Cute/Paste/SelectAll etc don't work.
Fortunately xterm is highly configurable. Some distros have started this process: debian, openSUSE and fedora use black-on-white colouration rather than the default 1980s white-on-black, and openSUSE and fedora also have a basic scrollbar.
It's not hard to make further improvements. All you have to do is to put appropriate settings into a
XTerm*VT100.translations: #override \n\ <Key>Prior: scroll-back(1,page) \n\ <Key>Next: scroll-forw(1,page) \n\ Ctrl<Key>Home: scroll-back(1000,page) \n\ Ctrl<Key>End: scroll-forw(1000,page) \n\ <Btn1Up>: select-end(PRIMARY, CLIPBOARD, CUT_BUFFER0) \n ! Make the scrollbar behave as it should in a modern gui XTerm*VT100.scrollbar.translations:#override \n\ <Btn5Down>:StartScroll(Forward) \n\ <Btn1Down>:StartScroll(Continuous) MoveThumb() NotifyThumb() \n\ <Btn4Down>:StartScroll(Backward) \n\ <Btn1Motion>:MoveThumb() NotifyThumb() \n\ <BtnUp>: NotifyScroll(Proportional) EndScroll() ! white text on black background XTerm.VT100*color0: white XTerm.VT100*color15: black ! Probably unnecessary, but to be safe: XTerm*foreground: rgb:FF/FF/FF XTerm*background: rgb:00/00/00 ! Scrollbar on the right XTerm*rightScrollBar: true XTerm*ScrollBar: true ! Prevent entering more text from causing a scroll-to-end XTerm*scrollTtyOutput: false ! Allow 5000 lines of history, rather than the default 64! XTerm*savelines: 5000 !Triple-click selects the whole history XTerm.vt100.on3Clicks: all !Use a nice and modern font xterm*faceName: Monospace:size=12:antialias=true
It won't take effect immediately unless you run the command:
$> xrdb -merge ~/.Xresources
This gives you:
The Btn1Up line makes the selection go both to the Primary selection and to the Clipboard.
I've not bothered with a Cut shortcut, which is unlikely to be useful in this situation. However I've so far failed to make Ctrl-A do Select-All (if you find a way, please let me know). Instead the XTerm.vt100.on3Clicks: all line makes Select-All happen for a mouse left triple-click.
There are plenty more options that you can set if you wish; see the xterm man page and many other places that your favourite search-engine will find for you.
