Erase bottom line at exit

Erase bottom line at exit

[okbob]

Can you describe more your idea? I am using pspg years from psql and I hadn't like this necessity.

How do you use pspg?

[Ximalas]

I run pspg from within psql, and to me it looks cleaner if the bottom line isn't a mix of the psql command prompt and the key hint bar when I exit pspg.

on my terminal pspg doesn't do this. Can you send screenshots? On my screenshots you can see the screen after leaving pspg, and there are not any key hints. What is your platform? What is your terminal? I remember that some BSD platforms don't correctly implement alternate screen in terminals.

I'm using FreeBSD current, MATE, Alacritty, and screen. See https://ximalas.info/~trond/pspg/pspg-001.png.

Yes, I thought so. https://unix.stackexchange.com/questions/235635/alternate-screen-on-freebsds-sc-and-vt Maybe I will write some workarounds. Unfortunately, I am not BSD user, and I don't know usual design for this issue. As workaround you can use option -X for pspg export PSQL_PAGER="pspg -X" psql It is not without unwanted visual artefacts, but it is better than without it (I think)

Actually, -X isn't that bad. Yes, it strips off the colours when I hit the q key, but the bottom line is erased before psql displays its command prompt.

[okbob]

now you can use options --at-end-clean, --at-end-reset and --at-end-erase-line.

export PSQL_PAGER="pspg --at-end-erase-line"
psql ...

please, check

I tried --at-end-erase-line and it's perfect. There is a typo for --at-end-erase-line in the help text, args.c, line 381. https://github.com/okbob/pspg/blob/master/src/args.c#L381

[Ximalas]

Maybe saying on exit is better than saying at end.

should be fixed now

This looks good to me. I hope others find this as a useful change.
