tmux refresh display after terminal width change
tmux does not currently support “reflow” or “rewrap” (following the behavior of xterm).
The author of tmux has written several times that he does not personally like the reflow behavior of screen, but that he would consider incorporating it into tmux (as an option, presumably) if someone else were to implement it.
Mailing list references (older first; not an exhaustive list, just what I pulled up with a bit of searching):
- Text Redraw/Reflow tmux vs screen
- 2 questions about working with tmux
- Redo line wrapping on resize
As of February 2013, reflow is supported by tmux!
Here's the commit.
