General issues with non-ncurses programs about abduco

[martanne]

Sorry for the late reply, I was busy with other things. abduco git switches to the alternate screen buffer before executing the given command. The issue you describe happens if the terminal doesn't support the alternate screen buffer in which case the cursor is most likely just placed at the left top most position, thus overwriting previous output.

As far as I know all modern terminal emulators are xterm compatible in this regard and support the alternate screen buffer. I tested it in st and dvtm git without problem. The one notable exception is the linux framebuffer console. Which terminal are you using?

It would be possible to query the terminfo database for the smcup/rmcup entries to use for the switch to the alternate screen buffer instead of hard coding xterm specific values. However I would like to avoid a dependency on termcap/terminfo libraries if possible. A somewhat hacky but less invasive change would be to check for $TERM=linux and avoid the use of the alternate screen buffer in this case.

I'm using st (0.5) and dvtm (0.12). This issue doesn't happen when running plain st without dvtm. Perhaps it is something to do with dvtm-0.12? I'll install dvtm-git later and report back.

Okay, yep. With dvtm-git installed, the issue disappears. I'll run on the git package for now then.
