DEL key not working

The keys HOME, END and DEL do not work in gnuplot. They output H, F and 3~ respectively.

I confirm the bug with feisty and gnuplot 4.0.0-5.

No, this not because gnuplot is not compiled with GNU readline. The builtin readline can handle those keys (it cannot handle autocompletion and perhaps history). However, it should handle HOME, END and DEL.

Yes, I've read that upstream bug, however I don't quite believe what is claimed there.

Can you please point out which Linux system has gnuplot compiled with builtin readline and have HOME, END, and DELETE keys working? In the upstream bug only the upstream developer can make it work in kconsole. The upstream bug reporter uses Gentoo, and Debian and Ubuntu both have this problem. It's a bit hard to imagine that all these distributions have "broken configuration".

Anyway, I'm not going to argue on this point since it's not my bug and it doesn't bother me.

Either the builtin readline supports HOME, END and DELETE, so this is a real bug in Ubuntu. Or either it doesn't and this is invalid since nobody can legally distribute binaries of gnuplot + gnu-readline. It is really sad that gnuplot developers do not wish to solve this issue: either change the license of gnuplot or drop support for gnu-readline so the builtin readline gets more attention).

Is there anything that can be done to move this along? It's over a year since the last comment and it's still a problem!

This is almost fixed in Jaunty, which has gnuplot 4.2.4-4 built with libedit. Only the DEL key doesn't work.

as of ibex, in gnuplot 4.2.3-1 HOME, END, DEL are still not working, but what is more annoying is when long gnuplot command line gets broken into several lines in current terminal width, the LEFT, RIGHT navigation also gets broken and it is impossible to edit such long lines. the only solution is resizing the terminal, but you can guess this does not go very far... i am sorry to say, but i am doing all my gnuplots on a gentoo box...

Darko, this has been fixed in Jaunty. I have some backported packages for Hardy in my PPA, maybe they will work on Intrepid.

Confirmed. Using Hardy Heron. gnuplot 4.2.4 compiled from source.

All keys work, except for DEL, which produces a tilde.

I'm running gnuplot 4.2 patchlevel 4, installed with apt-get, on Ubuntu 9.04 (Jaunty) 64 bits (AMD64).

I have a Compaq Presario V2000, with Jaunty and jJust got hit with this bug, my Del, Pg Up, Pg Dn, End, side arrow keys do not work.

I have tried changing the keyboard layout, Xorg, and running XEV, but no key stroke registers there.

Any suggestions?

Lacho: If you don't get keystrokes in Xev, then your problem is not a Gnuplot bug, and surely not this bug.

You'll probably have more luck amongst the Xserver bugs.

Thank you for taking the time to report this bug and helping to make Ubuntu better. I noticed that the package version your bugging is updated in Maverick. Please update via www.ubuntu.com repost a detailed error report, and update the bug status. Thanks!

I confirm, DEL produce ~.
Ubuntu 10.04 LTS; gnuplot 4.4.0-1~ppa2
