Text is not re-wrapped dynamically on terminal resize
Last modified: 2013-09-10 15:25:07 EDT
Description of problem: Text wrapped at column 80 (default) is not re-wrapped when the terminal is being resized. Earlier versions of Fedora supported this. This is a major problem since if you run a command which outputs a lot of long lines, you need to run it again in order to be able to make any sense of the output in a bigger window. Previously it was possible just to resize the terminal and lines would re-wrap automatically to match the terminal width. I'm not even sure this should be filed under termcap but it's really annoying. Version-Release number of selected component (if applicable): FC10 default How reproducible: Always Steps to Reproduce: 1. Start gnome-terminal or xterm or rxvt 2. Run the "export" shell command for example 3. Resize the terminal by expanding it horizontally by 10 or 20 columns Actual results: Text is cut off at column 80 and continued in a new line Expected results: Text re-wraps dynamically as the terminal is being resized, taking advantage of extra real estate Additional info: The same thing happens when the terminal size is being reduced instead of expanded. Text is not being re-wrapped.
This isn't related to termcap, it's a terminal emulator feature. I don't think xterm ever supported it, not sure about gnome-terminal. The only terminal I know that supports it is rxvt-unicode. Which versions of Fedora supported this?
I think FC7 supported this in gnome-terminal, I haven't used 8 or 9 extensively. I'm not 100% sure if it was a terinal feature though, but I'm sure that I could had dynamically wrapped text i.e. when logging in remotely. In fact, the bash command line re-wraps but the text which has already "been displayed" does not re-wrap. Where do you suggest I file this then? Sorry for troubling you.
Wrapping in bash command line is handled by readline, not the terminal. Ok, let's try reassigning it to gnome-terminal.
I'm 100% sure this never ever was implemented in gnome-terminal. I say that because I still don't know how to implement it without shovelling the entire vte code base. You probably piped it to less before. Anyway, the upstream bug for this is: http://bugzilla.gnome.org/show_bug.cgi?id=336238
I'm making great progress in implementing rewrapping in VTE (gnome-terminal etc.). Please see the upstream bug at https://bugzilla.gnome.org/show_bug.cgi?id=336238 , feel free to try my patch if you're a hacker kind. In case of any technical feedback, please comment in that upstream bug, thanks! Hopefully my work will soon end up in mainstream VTE.
