When running suckless' st terminal with the scrollback patch in conjunction with dvtm or tmux, the scrollback (patch) only shows blank lines (empty black space).

This doesn't seem to be a problem when running GNU screen. Is there a way to fix it?

tmux: https://github.com/tmux/tmux/wiki

  • Did you ever figure this out? – ram May 15 '21 at 00:09
  • Nope :(. I think may have something to do with TMUX spawning its own process. More on that [here](https://unix.stackexchange.com/questions/591756/suckless-dwm-swallow-patch-tmux). Not too sure about DVTM though, sorry. – T N May 16 '21 at 04:36

    I haven't looked at the code, but this repo has st working with scrollback in tmux. The commit says something about external piping. And I've officially switched to st https://github.com/lukesmithxyz/st – ram May 16 '21 at 07:24
  • [This](https://github.com/LukeSmithxyz/st/commit/7e6e779130327e065fcf587afa80f13150d0de31) looks like modification to two existing patches, [externalpipe](https://st.suckless.org/patches/externalpipe/) and [scrollback](https://st.suckless.org/patches/scrollback/). Didn't work for me when I applied a similar modification, but I'll dig deeper into it later. Thanks heaps for sharing though :)! – T N May 17 '21 at 08:56
  • No worries. Let me know if you figure it out exactly. – ram May 18 '21 at 02:00
