Tmux: Auto hide pane-border-status line when only one pane is displayed

[sc0ty]

Not a bug, a feature request.
The new pane-border-status option is great, I love it. But it would be even better if it had an auto-hide switch. It would hide border status line whenever only one pane is displayed (including zoomed pane).

This is why we wrote hook support.

Try these. you may need to tweak some of the values.

set-hook -g 'after-new-window' 'run-shell -b "if [ \#{window_panes} -eq 1 ]; then tmux set pane-border-status; fi"'
set-hook -g 'after-kill-pane' 'run-shell -b "if [ \#{window_panes} -eq 1 ]; then tmux set pane-border-status; fi"'
set-hook -g 'after-split-window' 'run-shell -b "if [ \#{window_panes} -gt 1 ]; then tmux set pane-border-status; fi"'

Nice trick! But, tmux set pane-border-status just toggles, so it doesn't work as expected. Plus, it needs to toggle when pane exits as well.

I've come up with:

# Auto hide pane-border-status line when only one pane is displayed (see tmux/tmux#566)
set-hook -g 'after-new-window'   'run-shell -b "if [ \#{window_panes} -eq 1 ]; then tmux set pane-border-status off; fi"'
set-hook -g 'after-kill-pane'    'run-shell -b "if [ \#{window_panes} -eq 1 ]; then tmux set pane-border-status off; fi"'
set-hook -g 'pane-exited'        'run-shell -b "if [ \#{window_panes} -eq 1 ]; then tmux set pane-border-status off; fi"'
set-hook -g 'after-split-window' 'run-shell -b "if [ \#{window_panes} -gt 1 ]; then tmux set pane-border-status top; fi"'

The OP also mentioned zoomed panes. This can be done with after-resize-pane. I've come up with this:

set-hook -g 'after-resize-pane'  "if-shell -F '#{||:#{==:#{window_panes},1},#{window_zoomed_flag}}' 'set -g pane-border-status off' 'set -g pane-border-status bottom'"

Using if-shell -F means that no sh process is even needed.
