That doesn't work.

But after I install Octave ("sudo make install") it works again, w/o your suggestion in comment #8.
And after installing Octave, it now also works when using ./run-octave &

So it is probably as you explained in comment #6.

Thanks for your attention & help, Mike

I will leave it to you if you want to reopen this.

Please try the following after starting Octave to see if this brings back the behavior that you like:

readline_read_init_file (sprintf ("%s%s%s",
                                  __octave_config_info__ ("startupfiledir"),
                                  filesep, "inputrc"));

This is copied verbatim from scripts/startup/version-rcfile.

It changed -AFAICS- around the start, or shortly before the start, of OctConf and it was already in 4.3.0+

I usually run Octave on Linux using ./run-octave &  (and now with --force-gui).
The latest "real" 4.3.0+ installation (make install) on my box is from March 2 and it still works OK there.

I wouldn't know how to track down which dependencies were updated when. Mageia has rpm, when I have more time I can try to read up on that.
It's no big deal, it's only me who seems to be affected and I use Octave on Linux mainly for testing (my colleagues are all on Windows so I use Octave by far the most on that platform).

Do you have a ~/.inputrc file or an /etc/inputrc file?

When did you notice this last working? Has it only broken since the first time you did a make install of 4.5.0+?

This may be the behavior that was changed some time ago in the 4.3 development branch, but since Octave doesn't overwrite its configuration files on make install, you probably didn't see it until the version number changed, so the make install paths changed.

It still doesn't work on my Linux build box while it works on Windows.
Maybe a dependency on the Linux side is in error (several of those were upgraded very recently)

Somehow it does work again.
I have no idea what was happening but I'm happy.

Closing report.

I should be more clear, sorry: it isn tab but command line completion using Up Arrow.

When typing the first characters of a command that was entered previously, then entering Up Arrow, a previous command matching those characters would come up (the last command that fits those characters). Using Up Arrow one can step through the list of matching commands. That doesn't work anymore.
Instead one gets the previous command whether it matches or not, and Up Arrow just steps through the history.

When typing a few characters and pressing Tab one gets the usual Q: show all <big number> possibilities? y/n

GUI mode.
Cannot try CLI now (cross-building in linux), I'll report tomorrow.

It works for me on both default and stable branches. Is this in console or GUI mode?

Subject says all.
I think this stopped working before the switch to 4.5.0+
In a build from before OctConf 2018 it still worked, in a build on Thursday (still 4.3.0+) is doesn't work anymore.
